I recently bought Z370 Extreme4 mobo and after upgrading the BIOS to 1.30 XMP stopped working properly. Windows would randomly freeze (almost always after stopping a CPU benchmark). Turning off XMP profile worked and I didn't experience any crashes after that. Later I downgraded BIOS to 1.22 and again turned on XMP. After the downgrade everything was fine so I'm sure there is an issue with the newest BIOS. My specs: CPU i7-8700K Motherboard ASRock Z370 Extreme4 RAM Corsair Vengeance LPX 16GB 3200MHz GPU MSI GeForce GTX 970 GAMING 4G Storage Samsung 850 Pro 256GB, WD Blue 1TB PSU Corsair RM650X Cooling Noctua NH-D15S Operating System Windows 10 Pro |

Thanks for sharing! I'm encountering a very similar issue with the following specs: 8700k/Z370 Extreme 4/GSKill TridentZ RGB 3200 14 CAS 2x8Gb/Gaming X Trio 1080 Ti/Seasonic Focus Plus Gold 850W. The RAM shows the Extreme 4 on its QVL list. I've tried every BIOS version, XMP/manual, bumping voltage to 1.4+, loosened timings; always crashes after a minute or two, guaranteed instant crash when stopping Prime95. Sometimes it even locks up at POST. If I drop the frequency down to 3000, however, it's completely stable. Took the same sticks, put them in a 7600k/Z270 Extreme 4, and the XMP settings work perfectly at 3200, passing every "stop a benchmark" test I could throw at it with no trouble whatsoever. I hope they address this soon, because I'm really wishing I'd gone with the Taichi or Gaming 7 at this point!

This is the first report of this situation with your board and UEFI version, although it has only been available for a week. While it might be an issue/bug, it is also possible that this occurs with your model of memory, but not others. That could still be a bug with your memory in particular. You said that XMP stopped working, but what does enabling the XMP profile do? It applies a built in over clock of the memory speed, sets some of the memory timings as needed for that speed, and increases the DRAM voltage. When the XMP profile is not enabled, the memory is running at its stock, default speed which is easier on the memory controller. What is really happening is your memory overclock seems to be causing Windows to freeze randomly after closing a CPU benchmark. Yes, the previous UEFI version with XMP enabled did not seem to cause the freezing in Windows. Are you absolutely certain that the UEFI option settings you used between the previous and new UEFI versions are absolutely identical? Including manually set voltages? Any comparison between the two must be identical. Can you see any differences in the memory settings and memory related voltages between the two UEFI versions with the XMP profile enabled? If you believe there is an issue, please file a support request with ASRock on this page, or via the support site for your region of the world: https://event.asrock.com/tsd.asp" rel="nofollow - https://event.asrock.com/tsd.asp ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Hello and sorry me again, i found out the the xmp profile on the 1.3 bios for extreme 4 board has set vccio and vccsa way to high. was set to 1.2 and 1.25 by default xmp. For me this was the reason why the system could not boot into windows and was unstable. I have now set xmp profile for my ram (3200) and then manually lowered vccio to 1.1V and vccsa to 1.15. Not the system is rock stable again ram running finally with xmp speeds corretly. Maybe this is helping one or another of you guys. Best regards flode |

Same issues here with G.Skill RipJaws V 2x16GB (=32GB total), DDR4-3200, CL14-14-14-34 (F4-3200C14D-16GVK) Windows freezes often when idle, the led of my keyboard goes off, screen stays on. My vccio was already set to 1.1. But vccsa was 1.2 so I'll try with 1.15. If I can't resolve this I have to return the board -.- |

" rel="nofollow - Hi, I just registered to report the same problem. I built my new system yesterday. i5-8600K 16GB G.Skill Flare X 14 3200 ( F4-3200C14D-16GFX ) Z370 Extreme 4 GTX 1080 Win 10 The board came with 1.10 and I flashed 1.30 immediately. Didn't know that it could be unstable, downloaded newest BIOS from official site. After installing Win 10 and everything, I went back to the UEFI and set XMP Profile from "Auto" to "Profile 1". After like 3-5 minutes in Windows, the system froze. Setting it back to "Auto", which makes my expensive RAM run with 2400Mhz, and everything is stable since then. Since my system is brand new, I didn't toy with any voltage settings in the UEFI at all. There seems to be something wrong with 1.30 and XMP Profiles. I didn't buy "3200-14-14-14-34" RAM to let it run at "2400-16-16-16-39". Is is possible to roll back to an older BIOS version without any issues? How fast will this be fixed? I have like 10 days left on my return policy. Oh, and PS: I really like ASRock Boards. I had a P67 Pro3 and after that, for many years, a Z77 Extreme4 with which I was very satisfied. Both served my good old Sandy Bridge well for many years. I wanted to be loyal, read some impressions of the Extreme4 and went with it. Hopefully this can be fixed. best regards Doc |

Me again. I tried the suggestion here from Flode. Loaded XMP Profile 1 and went to Voltage settings and set VCCIO to 1.10 and VCCSA to 1.15. Windows booted and I just ran a few minutes of custom/448-4096K/12000MB/not in place Prime95 run and it worked, no errors, did not freeze. So it pretty much must be those voltages. Hey ASRock, thank us later for finding that out for you ;) <3 |

These posts seem to confirm the issue. I say "seem" only because it is unusual for an issue to apply 100% of the time when there are hardware variables involved. The variables here are different models of memory, with differing OC speeds applied by the XMP profile. Enabling the XMP profile causes an automatic increase in the VCCIO and VCCSA voltages. That is not caused by the XMP profile itself, but the code in the UEFI. That is a standard adjustment when over clocking memory, it normally enhances stability. The interesting thing here is, all three users posting about this issue are using 3200 speed memory. My guess is the voltage values used for VCCIO and VCCSA when the XMP profile is enabled is simply one voltage value, regardless of the memory OC speed. A memory OC of 3200 is not a very high memory over clock relative to Intel Z370 and Z270 boards and the Kaby Lake and Coffee Lake processor's memory controllers. Memory over clocks for Z370 and some Z270 systems of over 4000 are possible. The high VCCIO and VCCSA voltages are more appropriate for use with memory over clocks over ~3600. The purpose of the high VCCIO and VCCSA voltages applied when the XMP profile is enabled is to insure (as much as possible) a memory OC will POST successfully. As we see with CPU over clocks, more VCore is needed, but too much is unnecessary and we reduce it to an appropriate value. The problem is all users are not aware of the need to configure the VCCIO and VCCSA voltages with memory over clocks. The memory OC potential of the memory controller is also a factor. The compromised solution is to set them on the high side. VCCIO and VCCSA voltages also tend to be "sweet spot" type voltages, the optimum values need to be dialed in for the memory being used, and the OC speed. Increasing them worked with memory over clocks, but too much was not known to cause stability issues, at least with Z270 systems. My ASRock Z270 board's UEFI also set the VCCIO and VCCSA voltages higher than was needed with my G.SKILL 3600 memory. But I did not experience any of the freezing issues described here. talos reported the same experience with his Z270 system. I am surprised that reducing those voltages caused the freezing to stop, given past experience. I'm glad that it did. It seems things have changed with the memory controllers in Coffee Lake processors. FYI, you can check the actual applied VCCIO and VCCSA voltages in the H/W Monitoring screen in the UEFI, and in Windows with programs such as HWiNFO64. My point is the actual/resulting voltage tends to be a bit more than the value entered for either option, according to the readings. You might want to select a slightly lower value for the option, to achieve a perfect result for your memory. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

I fully understand that those variables are important for overclocking memory also 3600 and 4000 speeds. But the issue here is people expect to select a XMP profile and then the system "should" be somewhat stable and not crashing. It took me some headache  to find out these values were to high for my system and caused the trouble. I also spent 200 bucks for a new memory kit because i thought the old one caused the problem.And yes actual voltage seems to be higher i set vccio 1.1 and it shows 1.12 in hwinfo. Same with vccsa.

HI, I can also verify that reducing the VCCIO and VCCSA voltage works and gets rid of the Windows 10 hangs. I am using G. Skill F4-3600c16-8GVK. Dropped the voltages to 1.12 and 1.17, respectively. Thanks to Flode from me also.

Same problem and working solution: - Asrock Z370 Extreme4 - 2x8Gb Patriot 3200Mhz PV416G320C6K - Intel i3-8100 - Ubuntu 17.10 Hangs up system every few hours, needs reboot. Though strangely error-less and solid in Memtest86+. Lowering the before mentioned voltages makes it solid as a rock at XMP profile. @Flode : you are THE man. Thanks |

My system specs: Intel Core i7 7700K @ stock ASRock z270 Extreme4 bios P2.30 G.SKILL Ripjaws V Series 32GB F4-3200C16D-32GVK (16GBx2) I dropped mine to 1.02V and 1.07V(same as yours but i took out a 1 and added a 0) and it seems to have stabilized XMP 3200 like the rest of you have reported. It would freeze within 20 seconds of me starting a game but that no longer happens so it must be fixed. Also should I increase my voltage or since its working fine should I just leave it alone? Its actually hard to even get the board to boot to even check out what the bios set them to when XMP was enabled so I just kind of set it to that to see what it would do. Also thank you flode!

" rel="nofollow - Hi everyone, I am using Mainboard ASROCK Z370 Pro4 updated to latest BIOS 1.5 with Intel I3-8100 I have this RAM VENGEANCE® RGB DDR4 DRAM 3000 MHz C15 (1x8GB) The XMP profile auto setting makes my PUBG PC 1.0 games always crash. ArcheAge also crashes. Even Dota 2 crashes too every 5-10 mins with FPS 200+ I have tried to set VCCIO to 1.1V and VCCSA to 1.15 but it no works.

Things first, 3000Mhz memory is OC and not guaranteed to work out of the box. 1 stick of memory has to go in slot A2 i believe. Do load the XMP profile, but manually refine it. Start with a safe setting that is stable and work your way up. Lowering the mem clock may help. It may also be possible to lower timings to counter the negative effect. Or do vice versa, raise them. Raise voltages of VCCSA or VDIMM Lower the CPU clock or cache clock may help. Im sure 3000mhz memory is easy to achieve, even on an "entry" board like this. Make sure you run prime95 and memtest a bit to make sure your system is stable. These tests are good. |

Just registered this account to say the Flode solution worked for me. I had been pulling my hair out trying to get my setup to work at 3200MHz but kept getting hit with complete freeze-ups at seemingly random times. Thanks to Flodes solution not only have I been able to run my ram at 3200MHz but I'm also able to maintain a 4.5GHz overclock on the CPU as well -- something I hadn't been able to do before. Just to reiterate -- my problem was fixed by entering the BIOS and selecting XMP Profile 1 for 3200MHz, then I went to advanced settings and manually edited the voltage settings of VCCIO to 1.1V and VCCSA to 1.15V. For reference, my build is as follows: -CPU: Intel i7-8700k -Memory: G.SKILL TridentZ RGB Series 16GB (2 x 8GB) DDR4 3200 (PC4 25600), Model F4-3200C14D-16GTZR -Motherboard: ASRock Z370 Extreme4 (obviously) -Storage: Samsung 850 Evo - 500gb -GFx Card: EVGA GTX 1080 SC -PSU: EVGA G2 850W I'll be running some more stress tests on the setup but it seems to be holding quite well. I cannot thank Flode and this community enough. I'll make sure to report back here if I run into any problems. (knock on wood)

Adjusting VCCIO and VCCSA voltages also seems to have worked for my recently built 8700K system. Still need to run a more thorough test to be sure, but no problems for about an hour now. Before, Windows would freeze up within 5 minutes of boot when using the XMP profile. Worked fine at Auto setting with much lower speed and higher timings. Unfortunately, I was not aware of this solution 3 weeks ago and spent a lot of time and stress troubleshooting/sending in the G.Skill RAM (Model F4-3200C14D-16GTZKW, which has the Extreme4 listed on the G.Skill QVL) for RMA only for the replacement sticks to behave exactly the same with this mobo. First ASRock product I've ever owned and I already regret it. |

Just wanted to chime back in 2 days after discovering this fix to say the problem has not reoccurred since applying the changes Flode sugguested. I have run MemTest86+ and Prime95 for hours to help confirm. I've been playing around with the settings since then and have actually been able to overclock my 8700k to 5.0GHz comfortably at 1.35V with idle temperatures hovering between 27-35C. I can go over the settings if there's any interest? It's crazy to think that just 2 days ago I was struggling just to keep this PC from freezing every 15 minutes. Anyway, thanks again to Flode -- because of you I am now able to fully enjoy my first PC build.  |

| Thanks for the fix Flode - I was seeing the same thing on my new board with an 8600k (no overclocking yet) while using 2x8GB 3200MHz G-Skill F4-3200C16D-16GTZB. I was crashing after about two minutes on any 3D app running the 1.10 BIOS out of the box. 1.10V and 1.15V did not work for me but 1.02V and 1.07V did after I flashed it to 1.30. I just replaced my ASRock Extreme4 Z77 and it ran like a tank for the last 5 years. Fix it soon ASRock, I've been bragging on you for a while now! |

Hmm i have been able to increase VCCSA to something like 1,32V to Support 3700Mhz RAM. But my VCCIO is at 1,15V. I initially had Problems but it appears that VCCSA wasnt the cause. |

I had to up my voltages to the recommended 1.1(1.096V in bios) 1.15(1.14V in bios) because I had my computer bsod after like 4 days uptime and at idle "PAGE_FAULT_IN_NONPAGED_AREA 0x00000050" The ASRock bios actually sets the voltages just a bit higher so I set them a bit lower and then its almost spot on. So those lower voltages may be slightly too low at least on my board which is a gen older Z270 Extreme4. After I set them up higher I then ran 4 passes with memtest86 and no errors within 5 hours of testing. Of course it was stable before but eventually showed signs on instability days later but hopefully its finally stable. I will update here if it crashes again.

Hello everyone, Just registered to post my thanks to Flode for the solution. Mine is a newly build machine with 8700K, Z370 Extreme 4, and G.SKILL F4-3600C16D-16GTZR (I didn't want the RGB, but those were much cheaper than the GTZ version...) After getting all the components and putting them together, the first thing I did was boot to BIOS and update to the latest available version. All seemed fine, and Windows installed on the new nVME drive without any issues. Then the problems started! I got exactly the same problem as in the first few posts in this topic - the machine would boot to Windows, and will run some tests/benches, but will freeze when left to idle or immediately after stopping say Prime95 (9 out of 10 times). My VCCIO and VCCSA voltages were set to 1.2 and 1.25 respectively after activating the memory XMP profile. As my XMP profile is at a bit higher speeds than the one in the original post - I lowered them both with just 0.1 to 1.1 and 1.15, and the machine is now rock stable! No matter what benches I throw at it or how long I leave it to idle! So the problem appears to happen with various ram modules certified for various XMP speeds, so maybe the new memory controllers just don't need that much voltage as older ones!!! Cheers! |

" rel="nofollow - hello, i just registered here to tell you that i had the same problem with my Extreme4/8700k and also fixed it by lowering voltages. Got Crucial B.

I would get freezes on my OC while it's rock stable with OCCT software. I manually changed all the voltages to the settings below and it stopped all freezes. Copy all my settings except DRAM voltage and CPU core voltage. Might want to lower VCCIO and VCCSA depending on your overclock. I'm running at 5.1 GHZ and 4200mhz on ram. You can reproduce the freezing with OCCT software pretty fast. If it doesn't freeze for 10 mins you're good.   |

" rel="nofollow - Just registered here say that I too am experiencing the same issue. I was so relieved to find this thread. I had built a new system last week using the Z370 Extreme4 with the i7 8700k and Corsair CMK16GX4M2B3200C16 Vengeance LPX 16 GB (2x8 GB). I started experiencing these random freezes whilst the system was idle. I had changed the ram to XMP Profile in the bios. I was initially running 1.1 but updated to 1.4 and as everything reverted to default in the bios the issue seemed fixed. I then went and readjusted my settings in the bios to the previous (custom fan speed and xmp etc) and the issue returned. It was then I did some specific googling and found this. Amazes this hasn't been fixed by asrock as of yet? Do they even monitor these forums? |

Probably not very actively, Did you attempt to fix your issue by adjusting the VCCIO and VCCSA as suggested by Flode on page 1? thats pretty much the only thing you can do now unless they push out another bios update including that fix.

| Looks like the main reason I don't freeze is because of using offset voltage instead of fixed voltage and lowering Cache ratio. |

Made the changes to the RAM voltage suggested by Flode. So far it seems rock solid. Many thanks to Flode for his work. My machine is now stable. Even have it OC'd to 5GHz with 50 millivolt offset. So far everything is rock solid. Using an air cooler and keeping temperatures around 75 or 76 under load. |

Glad I found this thread. Just built my first pc: Asrock z370 extreme 4 Intel i7 8700k 2x 8gb G.skill ripjaws V 3200mhz ddr4 MSI Geforce GTX 1080 Samsung 850 evo 500gb ssd Windows 10 The system ran fine at stock ram speed of 2133mhz. But trying to use the xmp profile I ran into the following problems: -System hangup anywhere from 10 seconds to 3 minutes after startup. No mouse or keyboard response. -No mouse response in bios -shutting down in Windows would turn the monitor off but the tower would stay on indefinitely until you hood down the power button. -mouse and or keyboard would shut off completely, no more backlight. -bios would revert to stock ram speed on its own I used Flodes suggested settings and haven't had an issue since!

I had a very similar issue, although not with the Z370 Extreme Pro4 but with the Z370 Taichi, but i builded around 15th of january and installed P1.4 from initial boot. Motherboard: Asrock Z370 Taichi CPU: Intel i7 8700K (delided) Memory: G.SKILL TridentZ RGB Series 32GB (2 x 16GB) DDR4 3200Mhz DIMM F4-3200C14D-32GTZR GPU: Asus GTX1080Ti Strix PSU: Seasonic Prime Titanium 750W SSD: Samsung 850 Pro 1TB HDD: WD RED 3TB OS: Windows 10 Home 64bit I had the random freezing for a week, but i did try other memory 2133 and still had the issue, mine did with xmp or not also. I since have reverted to P1.3 and i havent experience a full freeze yet, but it seems its not fixed fully, as i do get some time the busy cursor signal not doing anything, just it doesnt reach to a freeze. Ill be doing FLODE suggestion on chaning the voltages on the vccio/vccsa to see if its fixes it for me. Hope asrock test this issues for a future bios update for the Extreme4 and Taichi.

To be sure, I would also clear cmos (short the jumper), especially after a UEFI downgrade. Just to be sure. clear cmos (turn off, short the jumper with screwdriver/jumper) go to uefi and load defaults start from there, load XMP, manually lower VA and IO. |

I was about to rip my hair out.. I too have a z370 extreme 4 board and my ram is G Skills Ripjaws V 2x8gb (with a 3200 xmp profile) and I was having random freezes. Mine are veeery random though, and don't have a particular pattern. Anyway, on 1.3 and 1.4 I've been having these random freezing issues. (I'm still on 1.3) Decided to try that Flode guys voltage fix. The issue with my freezes is that they're so random that I can't force one.. so I won't know if its actually fixed for quite some time. If I don't experience a freeze over the next few days, I'll assume the issue has been resolved. Wish me luck! I'll update this post with my results. Update: So no freezing thus far. I even managed to finish my backups, which kept freezing but don't now. Changing the VCCIO to 1.10 and VCCSA to 1.15 actually managed to work successfully. Thanks again for the veeeery helpful tip Flode! |

" rel="nofollow - Did anyone had this issue try different memory slots? (Long story below), for my mobo, A1 will cause issue, A2, B1, B2 will work. IDK if it is a memory slot issue or defective or whatever, i ship my mobo back to replacement (to vendor, not AsRock RMA) *The memory is GSkill F4-3600C16D-16GTZ, GSkill list this mobo in QVL, although AsRock didn't I'd say it is the same issue, once XMP is enabled, it will not boot. I tried everything i can think, even bought a magnifier just to check bent pin. Because it works fine without XMP profile, so I never bother to try to switch slot.

But it still won't boot even i copy the working setting over Also there were a few weird things for the package. (So i didn't do the MIB, luckily I can do the replacement because of that..) There is no seal of any kind on the box nor the mobo bag. And the bios version is already the latest 1.3 (let's omit 1.4 for now). Bios version is ok, but i never had any Asus mobo box came with no seal at all. Is this normal for AsRock mobo?

I've only got two ram sticks so they're in A2 and B2. But, if you're noticing weird VCCSA and VCCIO voltages, just change them. If A1 lowers the voltages, higher them. VCCIO should be 1.1 or so (at least for me at 3200 xmp) and VCCSA should be about 1.15. |

" rel="nofollow - I'm having this issue with 2x8 Viper 3200's. I had G.Skill Tridents about a week ago but the motherboard completely crapped out on me. I got the replacement Z370 Extreme4 and ended up discovering that one of my RAM sticks was bad. Instead of waiting another bloody week waiting for new parts, I'm refunding the sticks and just bought these Vipers (PV416G320C5K) and I can't get XMP to work. Nor with Flode's suggestion. With my original G.Skill's, I was able to just toggle XMP and run with whatever stuff was automatically set, however, I was upgraded to 1.4. I did notice that once I got this replacement board, 1.4 was gone. So, my new board is 1.3 and I can't XMP. What do? :c They're in A2+B2 and seated properly. EDIT: This is what everything is set at by default without XMP. DRAM Voltage: 1.350V/Auto DRAM Activating Power Supply: 2.500V/Auto PCH +1.0 Voltage: 1.000V/Auto VCCIO: 0.950V/Auto VCCST: 1.000V/Auto VCCSA: 1.050V/Auto VCCPLL: 1.200V/Auto When it comes to computer knowledge, as an A+ Technician, RAM is a foggy area for me, no less the topic of voltages as well. I'm not sure if these voltages seem too high or too low and what to bump up or down. |

Don't tell people to try that.. there's a small chance that version can cause bricking, due to a change in the microcode for the Spectre/Meltdown issues. Why do you think they removed it in the first place, dude? That, and because it was fairly unstable and had a wealth of other problems. |

" rel="nofollow - [URL=][/URL]Good morning, I recently built my first proper System, I7 8700k Z370 extreme 4 Gskill Ripjaw v 3200 16GB (2PC) (Slots A2+B2) GTX1080 Seasonic prime 650W PSU Of course I´m having the XMP issue, but none of the Adjustments here suggested works for me. Even with a complety untouched Bios and a clean Windows install the System freeze within Seconds/Minutes. Only way to get it stable was setting VCCIO 1.10, VCCST 1.05, VCCSA 1.15, but of course only at 2333mhz without XMP. If I change any of these values by only a margin the system doesn´t even boot and I have to do a CMOS reset. Setting up the timings and mhz manually, PC won´t boot..... CMOS reset Tried 3000mhz/28.../26.. etc. Tried every available Bios version. It´s quite frustrating. It run´s perfectly with 2333mhz, rocksolid etc, but It kinda feels like driving a 1000HP Bugatti with only 800HP :-) It´s great, but it could be better. Do you guys have any suggestions ? Any help would be appreciated. Greetings from Germany Matthias |

Like in my other post I enabled XMP the first time and got BSoD's for days, and then I used memtest86, and it was throwing errors out, like an allyoucaneat buffet. I tried removing sticks, placing them in different places; nothing helped. I went back and inserted my RAM pieces back into slots A2,B2, and then enabled OC mode for CPU, and so far I haven't had issues with stresses, or anything else, yet. I am also however, receiving a replacement pack for my RAM, i'll see how it goes, and update from there(with stock CPU speed). |

Just wanted to chime in here by saying I had a complete new system built two weeks ago with the Z370 Extreme 4 mobo and was having the system freeze up several times every day...until yesterday. Yesterday I went into the BIOS and disabled C-State. I never touched the voltages or anything else in there (except for upping the fan speeds one notch for safety...this room gets hot in the Summer), but once I flipped the switch on C-States ALL of the freezing problems disappeared. I don't know if this will solve the problem for many of you--or if you WANT to solve it in this manner--but perhaps it will be of some use to someone. |

I also don't understand why ASRock is not fixing their buggy xmp voltage configurations. I have the z370 killer sli/ac and it also has voltage setting inconsistancies that make it very difficult to troubleshoot and get the xmp values. I have used two different sets of RAM, both on the QVL list, and had issues. With one of them the xmp auto actually overclocks the bclk frequency and I had to go in and manually fix it (set it back to 100 from 103). If they don't update the bios soon to fix these issues I won't purchase an ASROCK MB again. I have built a lot of systems over the years and had just come back to using ASRock again and this was dissapointing.

I feel the same way. I don't get what is so hard to fix about changing the default xmp voltages that they can't accomplish.. If they don't fix it by the time I plan to purchase a new mobo, I'm just avoiding ASRock mobos altogether.
