Ryzen 3700X instant crash in FPU test

Recommended Posts

Hello,

I just build a new System
CPU: Ryzen 3700X, Wraith Prism cooler
MoBo: AsRock Taichi x570
Ram: G.Skill Trident Z 3600 (CL16)
GPU: GTX780 (will be upgraded with a custom 5700xt)
PUS: BeQuiet Dark Power 11 750W 80+Platinum

I enabled the XMP2 Profile for my Ram everything else is stock no OC or anything.

First I noticed a crash in 3DMark TimeSpys CPU Test - my system would just go black and restart, so ne freezes, no bluescreens.

Then I ran AIDA64 in CPU mode - no crashes (10 min Run)

Then I ran the FPU test - crash within seconds, agian no bluescreen just blackscreen and restart


Is this normal for the new Ryzen generation?
Or do I have a defective CPU?

It's not normal at all.  I suspect there's a power delivery issue that prevents your CPU from working stable under heavy load.  My first move would be to try to get a replacement (or borrow one) PSU and check if it makes a difference.

Thanks for the quick answer!

I will try to find another PSU to test.

But I did another test with Ryzen Master open, there I can see the Wattage, Current etc.
Wattage and Current seemed well within range, but the temps were rising quite steeply and I stopped the test at 90° CPU Temp

Could the temps be the problem?

--UPDATE--

Ok tested it with a CoolerMaster 1000W PSU
Same Problems

Sometimes TimeSpy CPU runs sometimes it crashes

Same for AIDA FPU Test

--UPDATE--

I now lowered my RAM Speeds - I disabled the XMP2.0 Profile

Now it seems stable - no crashes so far in TimeSpy and I could run the FPU Test in AIDA64 for 5 Minutes wihout a crash (at 93°C)

 

But should my RAM/System not be able to run with its XMP Profile?
Or are the XMP Profiles generally "bad" or less stabel than an manual OC?

--UPDATE--

Went back up to xmp settings and Changed to PCIe Gen3

Still not 100% Stable with AIDA

No problems in timespy so far

Not all RAM and motherboard combinations will work with the XMP profile.  You may need to manually tweak the memory timings and DRAM voltage settings to make it stable.

I am playing with the settings a bit at the moment.

I can get it stable in normal windows usage and I get no errors in Ram test, even for hours.

One other Idea I found is that it could be the Infintiy Fabric that is unstable, this would explain why dedicated Ram tests don't show any errors but I still get crashes under load.

AFAIK lowering DRAM clock will also put less stress on the Infinity Fabric.
