Here is my build: - Ryzen 1600 (non x) - ASRock AB350M Pro4 AM4 AMD Promontory B350 Micro ATX AMD motherboard - EVGA GTX1060 6gb videocard - WD Black 500gb 7200 rpm 64mb cache hard disk drive - Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD - Corsair CP-9020122-NA 650W ATX12V 80 PLUS BRONZE Certified Active PFC Power Supply -G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) and the model number is F4-3200C16D-16GVKB I've updated the motherboard bios to version 2.4. I cannot get this thing to post with anything above 2133MHz for the RAM. I'm almost positive I have the RAM in the proper slots on the motherboard. Here is a vertical visualization of where I have the 2 sticks of 8gb. CPU A1 slot (empty) A2 slot (1 stick) B1 slot (empty) B2 slot (1 stick) Any thoughts on what I need to do? I'd obviously love to get the RAM up to 3200 or 2933. Heck, I'd even be happy with 2667 at this point. Thanks in advance. |

" rel="nofollow - I use slot A1 and B1 on my AB350M-Pro4, I get 2400mhz stable with 16gb G.skill f4-2800c15-8grbb , anything over 2400 won't boot. I tried another Crucial set 4x4gb 2400mhz (don't have the partnr handy) and it also booted 2400, but wasn't stable at all, even down to 1866mhz I got all kinds of errors and strange behavior. Also sometimes when I go in the bios, I can't navigate with the keyboard and have to use mouse. This happens at random it seems. As I mentioned in my thread, I also get horrible vdroop on the vcore.. I set 1.375v trying to get my 1700 stable at 4ghz, it reads 1.41v idle and then under load it drops down to 1.31v! Another thing is I get screen tear pretty bad with this setup when I scroll down and such, tho I'm guessing that is more driver related..? Hoping they can fix these issues in bios updates soon :) |

Ok, so I've got some more information on this board. It only currently supports 2400 MHz ram if you have dual channel ram. Mine is dual channel. If you have single channel....well I cannot say what your max should be because I have not researched that. Although the instruction book seems to indicate 2667MHz if you have single channel RAM (use slots A2 and B2). @TAMW - I'm pretty sure you should be using RAM slots A2 and B2. Give that a shot and see what you can do. By the way, even if you don't get higher RAM frequencies you should probably leave your RAM in slots A2 and B2 because you might get better results when the BIOS updates come out sometime this month (May 2017). Our motherboard does not currently have an option to adjust load line calibration. That is too bad because it is what you need to attempt to address that vdroop. I haven't found any options in the BIOS for adjusting the uncore voltage. Does anyone see this? (I'm pretty sure it does not exist at this time and they may never give us access since this is a budget board).

I whould think we should be getting VTT/uncore, pch voltage, and load line adjustments in the future, even the sub $100 z97m Anniversity I had with a 2+1 phase vrm had those options.. But I'm sure such features on these lowend boards aren't priority one over at ASrock. Fingers crossed. |

If you check your board's Memory QVL List, you'll find memory models up to 3000 that are supported in dual channel mode: http://www.asrock.com/mb/AMD/AB350M%20Pro4/index.asp#Memory" rel="nofollow - http://www.asrock.com/mb/AMD/AB350M%20Pro4/index.asp#Memory Memory compatibility is the biggest issue currently with Ryzen. If you check G.SKILL's list of compatible memory for the AB350M Pro4, you get this (sorry for the text link, some URLs fail in the forum editor link tool): http://www.gskill.com/en/configurator?manu=52&chip=2999&model=2993 A2 and B2 are the correct slots to use. I believe I recall another user of Ripjaws V memory in his Ryzen board also had poor results. The best description I've read about Ryzen memory compatibility is that it is a "crap shoot", meaning pure luck if it works or not. All of the existing (pre-Ryzen) DDR4 memory was designed for Intel systems, and the XMP profile data does not work with Ryzen. Memory that uses Samsung B-die memory chips has the best chance of working well with Ryzen. How are you configuring your memory, manually? Did you increase the DRAM voltage to 1.35V? What VCore voltage setting are you using? Auto, Offset, or Fixed? On some boards the LLC option won't appear when Auto is used. "Uncore" is really an Intel term, do you mean the SoC voltage? Hopefully your board will get an LLC option when the new AGESA 1.0.0.6 CPU microcode is released in May by AMD, but when that will happen, who knows? ------------- http://valid.x86.fr/48rujh" rel="nofollow">

@Parsec, Yes, I have been manually raising the DRAM voltage to 1.35 (I even tried 1.4 which I think is the max on this board at the moment). I also tried to up the ohms through the ProcODT setting by increasing it to 60. Robert Hallock from AMD gave a really nice overclocking 101 class. Here is the youtube link (start around minute 30) https://www.youtube.com/watch%3cv=KT8BQaQmL1U" rel="nofollow - https://www.youtube.com/watch?v=KT8BQaQmL1U He says never go over 80 for ProcODT. For VCore I was using 1.37 (which comes out to like 1.3685 or something) I change it from "Auto" to "Manual" which only opens up 2 new fields. (1) The CPU frequency and (2) the cpu voltage to allow for adjustments. The LLC does not appear when doing so. Yes, I do mean SoC voltage. Unfortunately, there is no option currently available for this board. The only voltage options besides the CPU voltage are further down the page under the RAM options and they are (1) DRAM voltage (2) 1.8 voltage and (3) VDDP voltage. I don't even mess with #2 and #3 when attempting to overclock the RAM. |

I'll try the a2b2 slots then. I've only tried up to 1.3v DRAM, as the spd only says 1.25v, will give 1.35v a go. And yes, I configure memory manual, tho there aren't a lot of settings, just the main timings, not even command rate. There is only Auto and Manual vcore settings for this board, but I guess manual is the same as fixed. I use manual of course. Btw, what exactly is VDDP voltage? The only voltage settings in the bios are Vcore, DRAM, "1.8v", and VDDP. |

| @TAMW, I don't have a good grasp of what VDDP voltage is, but the Youtube video I linked is of an AMD employee explaining many motherboard settings including VDDP voltage. I think his name is Robert Hallock. Check it out. |

" rel="nofollow - Might have to copy the links and paste/go. So here is the link to the above(mentioned by murander) long version... very informative. It is titled "MSI & AMD Dragon Squad | Robert Hallock?�s Entire Talk on Ryzen & Overclocking". https://www.youtube.com/watch?v=KT8BQaQmL1U Here is a link that contains the shorter version. It is titled "We Got Inside AMD?�s Texas Home - & Learned How To Overclock RAM on Ryzen - #DragonSquad". https://www.youtube.com/watch?v=vZgpHTaQ10k I watched them both just to see if there was any 'break thru' for my DDR4 @3200mhz that is currently running @2400mhz. It was a nice thought though, right? |

Yea, think we'll just have to wait for a more mature bios for this fukker.. :P With Load Line Calibration, Soc voltage adjustments and better ram support, this will be one hell of a budget board! :) |

I've got to ask you guys if you have tried any CPU overclocking and how successful you have been as far as stability with your overclocks. I have the Ryzen 1600 (non x). I cant get 3950 or even 3900 stable even at 1.39 volts. I should rephrase...i can boot into windows with those settings and run some stability tests, but invariably one of my stability tests will eventually fail.
I got off 3 successful cinebench runs but the 4th gave an error message midway through. No problems with any AiDA64 extreme benchmarks or handbrake rendering of a 350mb video. Prime95 can go for a couple hours but eventually fails. I'm kind of bummed because all my temperatures were fine. Under 65 celsius. I think they peaked around 62. |

Great job just to get to 3.9. If you can, adjust the core offset option to 0625 or 1250. Id also try CPU load line calibration to 4, possibly 3(if not set there already) to handle voltage drop. Also, 1.4v may be necessary for your CPU - perhaps even higher. I can get my 1800x to just over 4.1 stable but I don't want the high temps so I run at 3.95 and rarely see above 58c with a Noctua Air cooler. I'm not a 'big time' OC'-er as it is, so 3.95 is more than ok for my usage. In the video's mentioned earlier in the thread these things are covered well. Hope they help your efforts to reach your goal, because your temps are great. |

@Kevin A I'm surprised my temps are so good. I'm just using a stock cooler, but I did meticulously replace the stock thermal paste with some cooler master thermal paste I had. I also took time to cover the entire CPU except for a small portion of the diameter. I rubbed it in the best I could because I know its important to prevent air gaps. Anyway, you don't have the ASRock AB350M Pro 4 motherboard, do you? I should have done more research =( because this board has no options to adjust soc voltage or load line calibration. What do you mean by "core offset"? I'm pretty sure this board doesn't have that option either. |

In the UEFI of some ASRock Ryzen boards, the VCore option settings are Auto, Manual, and Offset. As you said, your board's UEFI does not have that setting. When Offset is selected, another option appears, Offset Voltage. Just another way to set VCore. VDDP is a memory related voltage for Ryzen, which is all I can tell you about it for now. Question for you, you are using the stock Wraith CPU cooler? You said it works well for you, how did you configure the fan speed in the UEFI? Using a default profile, or a custom one you created in the FAN-Tastic Tuning feature in the HW Monitoring screen? At least I hope your board has that feature. You could also configure the CPU fan speeds with the standard options in the HW Monitoring screen ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Ha, murander...you don't need to  . You have a 'great' overclock! The rest now will be DDR4 speeds and microcode updates over time from AMD/AsRock, Microsoft/Linux updates and then general Software/Game developer updates as the platform matures. You are off to a great start with the Ryzen 1600 that you have. The Wraith Spire is a decent cooler for the Ryzen CPU's that come with it. And your B350 supports overclocking, I checked the manual for your motherboard and right now it doesn't appear to be 'feature' rich in the UEFI/Bios(OC Tweaker Screen,that is...). But who knows, you may get more options as new Bios updates occur. Also, it is on the 'OC Tweaker Screen' that the options I mentioned in my earlier post are. My Fatality X370 Professional Gaming is heavily populated with options on that screen. Again, great job on your OC and temps. ---btw, your temps 'inspired' me to look into my own temps. I removed and cleaned my Noctua DH-14, applied some IC Diamond(used the Noctua NH-1 previously), re-oriented two 140mm case fans for more air in my Lian Li and ran a stress test over night. 52C was the high! @3.95 Not a bad 6C turn around

I have my 1700 running 3.8ghz, tried for 4ghz (which this cpu is definitely capable of) but because of the severe vdroop I'm getting, I just went back to 3.8. When LLC and Soc adjustments become availeble, I'll hit 4ghz+ for sure. You may experience the same problem as mine.. Try setting 1.39v like you did for 3.9ghz, but set cpu at 3.7 or something thats stable and check how the voltage behave under load (use hwinfo64 to check voltages). |

if you do get llc for your bios it shouldnt be too hard to get 3.9 ghz at 1.300 volts my cpu is there and quite happy about it as well ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

What speed I get at a spesific voltage is all chip related (assuming good enough cooling), some just overclocks better than others. I know I'll get 4ghz on this chip, as it held up for 10-20 seconds prime on 1.31v (1.375 set in bios).. Actually, this is cpu belongs to a friend, mine is on the way so I hope it oc's just as good.  I also bought a couple of vrm waterblocks dirt cheap used with variable mounting, hoping it will fit this board.. Just need them bios options  |

I had similar issues when i used GSkill Ripjaws memory F4-3000C15D-16GVKB. PC4 2400.. AFTER I SETUP SYSTEM WITH AMD A12 APU started having crashes.. I tried different things until i noticed the voltage on the mobo said auto at 1.20 when memory said 1.35v. I changed the voltage manually and that fixed the issue so far.. I been testing games and pushing it to confirm.. This memory is supposed to be XMP and the board supports it but it seems to be finicky about it. Asrock ab350m pro4 latest bios Amd A12 apu Gskill ripjaws v 3000 1 gig WD black Evga 500 power 80+ Note. Memory soes not reach full porential on the APU.

| Switched cpu to Ryzen 5 1400, new more stable board and still have issues with stability with this memory. I been using Corsair 2666 memory for now until i see if i can find a setting that will be stable. Have latest bios to this date. XMP reads the chips to almost 3000 mhz but do crash after few minutes.. Will try o. 1.2v at 2133 to see if gets stable. The issues with the A12-9800 went away, but the memory limitation of the cpu does not let u get faster ram. |
