Asrock Killer SLI/AC X370 cannot get higher than 2133 - Page 7

post #61 of 169
Ok.....today's project...leaving RAM at 3200, but might try lowering CAS to 15 (I know, I'm being greedy!)

Let's have Lazerus make us some money!




3.8@ 1.325 v. (thanks for post last night, lowered voltage today).

Nicehash only hits CPU at 50% - stable as all hell. GPU (RX480 4GB) is at 100% - I have it clocked at 1350/ 1800 currently - 72C as you can see.

I don't pay for electricity at this place! Lol....time to experiment!

Hey all, new-ish to OCN but just chiming in here with my experience with this board.

Got this board paired with a 1700 and 2x8GB PNY Anarchy 2400MHz CAS 14 1.2v. Had it for basically since launch and still having trouble with memory stability. Getting blue screens on a daily basis relating to memory management, system exception, and the like. I've reinstalled Windows, tried nearly every BIOS version, overvolted and underclocked RAM, and tried everything I can think of. Usually will crash when change in load such as launching/closing a program and do it several times if I don't reset BIOS or let it sit off for a while. CPU overclock has no effect on it, can run CPU-Z stable at 3.9GHz or overvolted at stock, same thing. I'll have several days of light usage like Netflix without issue but gaming or any significant usage will freak it out. RAM does not officially support XMP but BIOS reads it as XMP and either setting it to that or manually will be unstable.

Was able to test with a kit of 2x4GB Kingston HyperX 2133 CAS 14 1.2V and runs flawlessly. Can stress at 3.9GHz and it's rock solid. About to give up on this RAM but will need to sell it so would like to get it working if possible. Ran a pass of Memtest+ and it's passed so pretty sure it just doesn't cooperate with my board and the rAM itself is fine.

Anything else I can try? Just wait for newer BIOS? Might try really overvolting the RAM but don't want to damage it.

Also weird side note but I installed W10 in UEFI mode with CSM disabled and onto an SSD. Worked fine and BIOS would boot in 2-3 seconds. Noticed after a week or so that CSM was back on again and if I disabled it I'd get 5 beeps and no POST. Anybody else had issues like that? Don't want to reinstall Windows if I don't have to.

Hey guys, quick update on my end. I've just updated to the 2.00 BIOS but it has made no difference with my RAM (GSKILL 3200 CL16 32GB Kit) 2933MHz CL18 is still my limit so I've reverted back to my old 2666MHz CL14 setting for now as I prefer to believe it's faster than 2933/18.

On the CPU side all my settings are still the same and stable. I did notice CPUZ and HWMONITOR now report the full voltage rather than half voltages and having a computer do math for me no matter how simple always makes me happy biggrin.gif

If you're already stable on an older BIOS then I don't think you need to rush out and update to 2.0, at least I haven't seen any difference yet other than some minor superficial improvements.

by what I am seeing, the faster MT/s is more important on the Ryzen than the latency. (fabric speeds)
I know you prefer to think 2666/cl14 is faster than 2933/cl18 - but no test will show this.
have you attempted 2933/cl16?

Still stuck at 2133 anything higher than that system is unstable. this ram issue really is getting old. I am tired of having to use such slow speeds on my ram. no matter what i set my clock speeds at i will at best only get one boot before it become unstable and reverts back to 2133.

Yes; 2933/15-15-15-15-35, 2933/16-15-15-15-35 and 2933/16-16-16-16-36(stock timings) all failed but oddly 2933/17-15-15-15-35 will boot but is read as 18-15-15-15-35 in CPU-Z. Btw I set my DRAM Voltage to 1.39v but found, 1.355v and even AUTO boots just fine with these settings.

Do you mean benchmark tests are in fact showing 2933/18 beating out 2666/14 on Ryzen or that there is no test that can isolate the effects of latency vs clock speeds?

It's taking too long for the agesa 1.0.0.4 update for this board... Well, for all Asrock boards in fact, come on Asrock!

Maybe they waited a bit to test with the new build of windows, the creators update.

you guys do know the AGESA 1.0.0.4a is in 2.00 right?
