Ryzen + RAM stability testing

[pitA]

At what point can a system be considered stable?

 

Running mprime blend test failed after about 7 hours. The small FFT test has been running for ~15 hours with no errors. mprime's documentation suggests failing the blend test but not failing the small FFT test may indicate memory issues.

 

Aside from the mprime test fail, I have not had any problems/crashes so far while using the system. It still bugs me though.

 

Ryzen 2700X

Crosshair VII Hero Wifi

2 X 16GB G.Skill F4-3200C14D-32GTZ (set by DOCP to the kit's rated specs of 3200MT/s, 14-14-14-34, 1.35V)

Do things you normally do any if it crashes it isn't stable.

I agree with this. If it does everything you need it to without problems, then it could be considered stable.

Honestly I have had it where something like this would happen to me during stress test and it would crash after a long time. Then I kept the settings and it never crashed under my normal use. Stress tests are exactly what the name implys. It stessses your system to make sure the system is stable under any conditions. Because my normal use isn't nearly as stressful as the stress test I was fine. I mean honestly if the thing can last 16 hours strait of stress testing before it crashes then I would say there is a good chance that it may never crash from normal use.

Practical people.

 

It's a new system so I haven't used it extensively but so far no crashes or issues in normal use. But normal could be browsing web pages, or it could be training machine learning models for hours (haven't tried that yet). ML isn't generally sensitive to small errors, but the thought of my computer being inconsistent still bugs me.

 

Considering running Memtest later.

 

Given Ryzen's past troubles with RAM, I want to make sure RAM is ok at its rated specs before tuning other parts of the system.

It passed Memtest86. 7 hours and 4 passes of all tests with no errors.

 

I noticed there's a BIOS entry for DRAM power limits (100% to 130% in 10% increments) and it suggests increasing the limit for current-intensive memory stress testing. I might try mprime blend test again with 110%.

[pitA]

Still got fails at DOCP + DRAM current limit at 110%.

 

At default JEDEC settings (2133MT/s, CL15/16?, 1.2V, etc), mprime blend test had no errors in over 24 hours.

 

Any tips on tuning memory to get XMP stable?

 

Also, I read a post by Raja@ASUS on the ROG forum from a few years back recommending Google's stressapptest for memory testing, and that it was preferred over HCI. Is that still true, and valid for Ryzen?
