RAM Speed Issues

[Lord_Snax]

Howdy All,
I have have a RAM issue with my new build.

My Build,
CPU: Ryzen 5 1600

mobo: ASRock AB350M Pro4 BIOS ver. P2.40

RAM: 16GB 2666MHz 2x8GB

SSD: Samsung 840 EVO 250GB

HDD: WD Blue 1TB 7200RPM

GPU: EVGA Nvidia 1060 6GB SSC

PSU: Corsair CX600M 600 Watt

Case: Master Case Pro 3 by Cooler Master

The RAM I originally purchased was a 2666MHz 16GB RAM kit by G.Skill. As I was testing I could not get the RAM to run any faster than 2133MHz. When I would try to set the motherboard to run the RAM at 2666MHz via the XMP profile settings, the motherboard would not POST.

Checking the RAM compatibility list on ASRock's website, something I should have done the first time, I noticed that my G.Skill RAM kit was not on the list. After some research I picked up a Corsiar Vengeance LPX 16GB 2666MHz kit that was labeled on the compatibility list.

After much trial and error, I am back at square one. I still cannot get the Corsair kit to run faster than 2133MHz. I was able to get it to run at 2400MHz but the RAM was very unstable. Even at 1.3v, the highest my motherboard would go before it starts red flagging my settings.

I really wanted to run my RAM at 2666MHz, but I am at a loss here, and am unsure what to do next. Any help would be greatly appreciated.

Thanks,

Lord Snax

Any BIOS updates to push?

RAM speed on Ryzen has been finicky, though it is improving. I find you usually have to train the RAM speed in. Try upping it in the smallest increments possible, and then burning it in with a stress test each time, while overestimating voltage to the limit of safe. Once you manage a full burn in with 2666, you'll usually be able to slowly dial the voltage back down while remaining stable.

I am running the latest version listed on the ASRock website. BIOS ver. 2.40.

How far should I push the voltage? My motherboard red flags the voltage field when I try to input anything higher than 1.3 volts.

I've heard 1.35v as the recommended limit for normal people

AsRock BIOSs red flag most voltages that are outside spec, so I wouldn't worry about that. XMP certification can be done at up to 1.5V, though that wouldn't be a good idea, especially for a B350 board. Try 1.36V for starters at 2400 and see if you can get it to run stable in a stress test. If you can, try bumping it up to 2666 at the same voltage, and see how it goes.

 

Let us know how far you get with these.

My motherboard strangely only jumps in .05 volt increments, I tried 2400MHz at 1.35 volts but didn't get anywhere.

 

I am also working with ASRock Tech Support and he is having me run with one stick and see if that helps. So far, he had me enable XMP profile at 2400MHz and it is much more stable with a few random restarts here and there, but no restarts yet with aida64 stress test.

One stick is always more stable at a given voltage, for multiple reasons like the voltage not being divided, and single channel RAM operation is less complex. Don't worry too much about bumping up the voltage as long as it's under 1.5V. Get it stable in AIDA64, then try dropping it. You'll usually find that burning it in, then dropping it will work best, and it really seems to be the case on Ryzen.

 

I highly doubt your memory is bad either, the memory controller microcode of Ryzen is just known for being a pain. I believe there was a recent update to the X370 BIOSs, so B350 might just be lagging behind and getting it soon, which should help.

Thanks for the info.

 

I just started up Witcher 3 shortly after posting my last post and my PC crashed. So still not stable enough.

Well, ASRock says their Corsair Vengeance kit works at 2666MHz with no issues, and they are suggesting that I exchange the motherboard and RAM.

 

What do you guys think?

[bcguru9384]

your mobo says if 2667 single or double density ram then only dimm A2 maybe populated

if 2100mhz then multi dimm population is possible

i did bing search on your mobo this was info from asrock site

I see on the website and in the motherboard's manual a listing about single rank and dual rank modules. I have no idea witch rank I have as its not listed on the RAM sticks. So if I understand what you are saying correctly, I should get faster RAM?

 

 

[bcguru9384]

no

you need to put just one of your 2 sticks into the A2 ram slot since very likely you have ddr ram not sdr ram.

ram will have only one slot populated

empty populate empty empty

if you have sdr ram 

empty populate empty populate

2100mhz sd ram you may populate all 4 dimm slots

the website has spec chart with 3 symbols,,,, - means empty slot ,,, s means single density ,,, d means double density

What are you calling "sdr" and "ddr"? Single rank and duel rank?

The RAM I have is single rank RAM.

 

According to ASRock tech support, the RAM kit I have should work. They got their test machine with the same model motherboard and RAM to run at 2666Mhz. So I followed their advice to RMA the board. The new one should be here Monday (the 22nd) and I will see if that fixes the issue.

Yup! ASRock just released an update (P2.50) that fixed my memory issue. I am running both RAM sticks at 2667Mhz with no problem.

 

Thanks for the help everybody!
