Zen 4 diagnostic - your thoughts? (Patreon)
Content
I think many of you have encountered the problem when the values after diagnostics for CO are positive, not even 0.
Here is my example, the core has already a value of +2. So the factory values are unstable?
Let's get to the bottom of this.
Prime95 is currently being used to diagnose the processor. I am neither its developer nor co-author. I and other well-known enthusiasts in the process of research have set up settings that effectively find errors. As it happens, the current load level created by Prime95 in AVX mode demonstrates even the instability of the stock processor, and temperatures are at the threshold of 95 degrees.
AVX in Prime95 turns out to be even heavier than AVX512. SSE = AVX2. There are 3 outcomes of this event:
1) Wait for Prime95 author to make adjustments to the code of his product or AMD to make throttling adjustments for such scenarios. I don't believe any of them will do anything.
2) Continue to use this approach and get information that some cores are unstable even in stock, but in this case even a super mega heavy stress test will be passed.
3) Refuse to use AVX for Zen 4 in Prime95. Test with SSE and get results that will satisfy stability in 3D Mark, Games, Cinebench R23 and so on. The problem with this approach is that users who are used to testing in mega-heavy super-stress tests will get instability, and as a consequence a flurry of indignation in all forums and chats.
What to do in this case?
Note 1. Fortunately Zen 3 is past such a problem, Prime 95 generates the appropriate load. The problem only exists for Zen 4.
Note 2. OCCT I do not consider it because the problem is similar there + error detection as such is absent (except of course for scenarios of super mega load activation which will prove that CO 0 is unstable).

Alternative. At the moment I'm doing research that might be a solution to the Zen 4 diagnostic problem. No details yet, but keep your fingers crossed for me.
