Hi, I have had a ryzen 2700x since the release day, and there has been a stutter problem with the CPU, that requires complete restart for it to unlock.
it usually happens when CPU utilization jumps from idle, to full load... - the screen freezes, with all commands not functioning (num lock doesnt work either). So far I've waited upto a minute, and it still wouldnt "unlock".
I tried finding a solution on reddit, and someone suggested changing the power mode in bios to "classic" or something along those lines, but it didnt help much. So here I am trying to find a solution.
I tried stress testing ram and gpu but none of them show any problems.
also, its not overheating... the temps are in 40-60 range. - no overclock.
The error happens on most CPU intensive apps, but for me most common is in 3DS max. Happens at least once every 4-6 hours of normal work load.
Also, the software is not to blame, since works on all other computers I've worked with.
my setup is
gigabyte 470x aorus gaming 7
16gb of 3000 ram (g skill)
titan X (pascal)
750 watt corsair PSU.
Unfortunately I can't post a solution but I can say it's (almost) what I am fighting with at the moment. For me, Maya is also being unstable at times and randomly locks up.
There have been 3 bios releases for your motherboard, please advise your bios version so people can get an idea on your system. Also include your power plan from Power option as it seems it gets choked from idle to full load. May I suggest that you download KeyShot and run the benchmark camera test and let it render for 10 mins and rotate and let it render again, this will test all your cores. regards.
hi, thanks for the reply.
At the time of writing that post, I was still using F4G bios (the mbo came with it, and I had it basically since first week 2700x was released), and had updated to F4 last week.
since then, I havent used the computer enough to have scientific certainty, but so far I've had few friezes while using "power saver" profile -me not being certain is because at those particular moments, computer was really at its limit, so the freeze could have been caused by ram or gpu getting flooded (although they rarely misbehaved in the past).
I'll switch to "Ryzen balanced" in a few days and let you know how it goes on each of the power setting modes.
as for benchmarking, I'm running 3Ds max and Vray on it, and multiple instances of it, and other software -so it's getting properly "abused" as is. But the bug is not instantly repeatable. Sometimes it'd happen after 2 mins since turning the PC on from standby, sometimes after 20 min. And I would not need to wait for it to render.. it'd happen instantly when I pressed the render button - in the exact same moment when the "cpu load spike" happens.
updating sooner then I thought.
I had a busy day today... and I've reverted back to F4G.
When using photoshop, the pc started acting up. It started to behave erratic, with crashes after 5-15 mins of use. no matter if computer was in stand by beforehand.
(the crashes were different then before. The PC wouldnt actually crash, but windows would stop behaving properly. With different parts of UI not functioning properly).
1) using ryzen master to put it to both in gaming and productivity mode... no difference
2) tried using performance, power saver and ryzen balanced power settings ... kept crashing
3) tried manually setting DRAM Vcore to 1.35 ... kept crashing
4) tried optimized defaults in bios ... kept crashing
5) reseated ram, reseated GPU ...kept crashing
now I'm back to F4G bios (I keep reading it l33t ), and it's working without a glitch as long as I dont go into stand by.
I'll try F4 again in a few days when I have more time on my hands... since I still leave some doubt that I might have f* something up. Will try it with my old gtx 580 and 1 by 1 stick of ram to exclude anything else being an issue (and yes, I've got ram inserted in correct slots). In that case, I really hope someone could direct me to an AMD representative...
Also, there was a weird glitch when PC was booting... the "_" cursor that's usually pops up for few seconds top left corner, would appear slightly offset toward mid screen.
After few days of intensive work load that caused 10s of crashes, or temporary stalls, I can confirm that F4 patch didnt help at all, as I had gone back to F4G, and then F4 again without noticing serious improvement.
To remove any doubt, I tried re-seating ram, and working with only 1 stick at the time
I also tried different graphics card, then 2 graphic card same time, neither helped.
I also tried unplugging hard drives, that didnt
I did a fresh windows install; That didnt help either.
In the end, I resorted to tinkering through bios on my own, and I over-volted few parameters of CPU and DRAM slightly above stock values. And it seems to be working far better then anything before (24h without hickups attm).
my best guess at what's going on with the freezes is this:
1) during standby, PC temp drops low (20C,30C)
2) when I turn on the PC, it boots up, and keeps a conservative speed
3) when I start a CPU intensive app, the MBO/CPU senses it can "go faster", based on current idle tem
4) MBO/CPU based on that raise the speed, but keep the voltage of components low
5) the freeze happens, either because CPU or DRAM is not getting enough voltage
current bios settings are:
Host BCLK 104.5 (upped it from 100)
CPU speed: 3920
DRAM frequency: 2925
CPU vcore - auto (1.225V)
VCORE SOC 1.20625 V
CPU VDD18 1.92 V
DRAM Voltage 1.25V
DRAM Termination 0.7V
CPU VCORE Loadline calibration Turbo
VCORE SOC Loadline calibration Turbo
Is there a way for me to disable PBO2 to see if that helps?
And where can I find all AMD recommended CPU voltages, since I'm afraid the MBO Auto settings might be screwing things up.
sort of.I havent had a freeze for 3 weeks now, but I also disabled standby mode completely, so cant be certain that it wont start freezing once I go into standby again
I did everything possible, so I'm not sure which one did the trick exactly, but I suspect my motherboard tinkering is most important I still suggest reading the whole list to make sure you did all the simple things first:
1) I have flashed the BIOS to the latest version
2) I re-seated all components (CPU, RAM, GPU)
3) I set windows power mode to "High performance power mode" - make sure your processor is set to "minimum processor state 100%"
4) I downloaded the latest chipset driver; take note that AMD's official web site didnt have the latest one, but I got the latest one from Gigabyte's website.
5) I uninstalled all diagnostics and control tools from windows (such as CPU/GPU Z, afterburner, ryzen master, and bios tools, since I've noticed that they cause instability in the system
I changed these settings in BIOS:
6) I set the CPU and RAM speed manually;
CPU @ 3800 mhz, and ram @ 3000 mhz
CPU VCORE Loadline calibration Turbo (I think this is the most important part) (it doesnt need to be turbo, but anything higher then default)
VCORE SOC Loadline calibration Turbo (I think this is the most important part) (it doesnt need to be turbo, but anything higher then default)
I'll take a look in my bios settings, and report if there's something else I forgot to mention.
If nothing from the above helps, I suggest you try setting all possible CPU settings manually to conservative values, and if it works slowly roll back to Auto, to see if that helps at all.
P.S. please report how it goes for you after making all the tweaks; Or if you manage to diagnose that one of the bullets I recomended had higher impact then the others. also, you might go directly to Loadline calibration settings, to see if that stops the problem instantly, since I didnt get a chance to benchmark it alone... and would be helpfull for others if that turns out to be the sole fix.
Thank you for your reply.
I am on 2700x stock, ROG Crosshair Hero VI, g.skil tridentz 3200 cl16 (@3400 cl16 v1.36, tested 10h in nemtest = 100%RS),Rx580, AX760w. Even if I keep all the system stock (ram 2133 etc) it doesn't help at all.
I have already done step 1, 2 & 4. Also I just fresh install windows 10 (I thought it was the problem cause I swap a lot of cpu , mb and ram in the last month without formatting).
I will try the power plan " performance ", actually I am on balanced (25%-100%).
I am on lvl5 (the highest) cause I notice it helps with these system locks, but still have the issue. Never try SOC LLC so I will give it a try.
I will try also the 5th step and I will also set the clock manually.
I'll start with LLC then step by step trying all the others advices you suggest.
Thank you for your time.
I'll keep you update.
Have a nice day
