NIoSaT Posted August 11, 2019 Share Posted August 11, 2019 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? Greetings NIoSaT Quote Link to comment Share on other sites More sharing options...

My first move would be to try to get a replacement (or borrow one) PSU and check if it makes a difference. Quote Link to comment Share on other sites More sharing options...
NIoSaT Posted August 11, 2019 Author Share Posted August 11, 2019 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?

NIoSaT Posted August 11, 2019 Author Share Posted August 11, 2019 --UPDATE-- Ok tested it with a CoolerMaster 1000W PSU Same Problems Sometimes TimeSpy CPU runs sometimes it crashes Same for AIDA FPU Test Quote Link to comment Share on other sites More sharing options...
NIoSaT Posted August 11, 2019 Author Share Posted August 11, 2019 --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? Quote Link to comment Share on other sites More sharing options...
NIoSaT Posted August 12, 2019 Author Share Posted August 12, 2019 --UPDATE-- Went back up to xmp settings and Changed to PCIe Gen3 Still not 100% Stable with AIDA No problems in timespy so far Quote Link to comment Share on other sites More sharing options...

You may need to manually tweak the memory timings and DRAM voltage settings to make it stable. Quote Link to comment Share on other sites More sharing options...
NIoSaT Posted August 14, 2019 Author Share Posted August 14, 2019 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. Quote Link to comment Share on other sites More sharing options...
