Got my 5800x finally to begin testing for a day, on Asus X570 plus bios 3405 using corsair h110i, ctr cinebench avx2 test hit 90C less than 1 min and terminated, can't really cool 142w on such a small die.
I watch the guide at
to quickly see what should be done as review doesn't discuss it in length.
CTR2.0 show my core as silver sample
Adjusting auto oc to 200 give me a max of 175 at 5025mhz with higher cppg rating, which every core is capable of hitting according to hwinfo.
With auto LLC, CTR warn of vdroop, so I am using level 2 at the moment only with CPU vcore at auto in BIOS.
The problem seem to be that two of the cores with no auto oc, no curve optimizer, disabled pbo, can't even pass p95 smallest fft at 2 threads by setting process affinity to the associated threads.
+200 test AVX2 p95 smallest fft, 1T ~4725, 2T ~4625
C01,2,4,5,7,8 pass a simple 0.5-1 hr avx2 1 or 2 thread affinity p95 test, but C03,06 fail pretty much immediately. The app simply crash without error which is great, at least it doesn't get BSOD this way.
C02 – T2/3 , -15 curve pass p95 smallest fft 0.5 hr 1/2 thread
C03 – T4/5, +5 2T 4550 fail, +10 2T 4480-4510 ok
C06 – T10/11 0 fail
So I actually have to set to +10 on C03 to make p95 happy by bending the frequency curve down when setting affinity to stress test a particular core at 2T level, will have to do the same for C06.
It looks like even though Windows Scheduler will assign low level tasks to my best core C02 C04 which I can do probably at -15 and more, but I have to add some positive evil volt to the curve on my worst core. So either Asus auto vcore is not enough or AMD latest QC isn't good as default volt/speed fail on some cores?
edit:
With LLC lvl2, +10 would still fail at C06. Setting LLC back to auto make it work. So it's LLC being too weak. +1 to the video, -1 to CTR, doesn't seem to be Asus/AMD fault.
Now I will have to start from the beginning with auto LLC. This is going to take a long time to play.
With auto LLC, weakest C03 is still failing without adding positive curve.
