Without XMP those voltages seem normal.. I guess.
The XMP on my ram is 3200 as well, but I have 2x8gb G Skill Ripjaws V. My voltages with XMP turned on are: DRAM Voltage: 1.350v/Auto DRAM Activating PS: 2.500v/Auto PCH +1.0 Voltage: 1.000v/Auto VCCIO: 1.100v/Manual VCCST: 1.150v/Auto(?) VCCSA: 1.150v/Manual VCCPL: 1.200v/Auto Those voltages work for me.. before, with XMP VCCIO was 1.2v and VCCSA was 1.25v. But that caused random freezing for me. Altered them like the guy on page one said, and it works brilliant. |

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. Edited by DomoSapienXD - 02 Feb 2018 at 4:33pm |

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.

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. Somehow This is the voltage setting when A1 is inserted: https://i.imgur.com/t7B8T6c.png This is the voltage setting when A1 is NOT inserted: https://i.imgur.com/LzRNTL8.png *VCCSA is 1.25 from auto, accidentally typed it again The reason is A1 reads incorrect setting, cause unknown. 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 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! Edited by eballen - 30 Jan 2018 at 12:42pm |

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. Edited by DocBrown - 28 Jan 2018 at 11:44pm |

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.

Then I think I am lucky I didn't update to 1.40.

1.4 was taken down because Intel f***d up big time with spectre patch (random reboots)
