While waiting for reply from Asus tech support, I did some more tests today.
Using offset mode and ac/dc settings, I marked down few stable configurations.
Common settings: Multiplier - 50x, AVX offset - 0, MCE - remove all limits, LLC - 4, Voltage mode - offset, xmp is disabled
Offset mV, ac mOhm, dc mOhm -- temp C, vcore, current A (avg values under load p95 40k)
A. 10, 0.5, 1.3 -- 95.0, 1.186, 190.5
B. 20, 4.5, 1.3 -- 94.6, 1.182, 189.0
C. 30, 4.0, 1.3 -- 93.8, 1.182, 188.8
So far so good, but ... In the late afternoon I did retest the same settings, and each of them is giving the same voltages, temperature and current, but they fail (usually in the first 5 minutes)!!!!
The ambient temperature at home is about 24-25 degrees all the time. The VRM temperatures are also close. The PC has been running from the morning and I think that the issue may be related to the temperature of the motherboard component that is making problems when it gets hot.
Set VCCIO to 1.20v. VCCSA to 1.25v, PLL Terminiation to 1.10v, Internal PLL Voltage to 1.0v, PLL Bandwidth to level 0, Standby voltage to 1.05v then test again.
Hi Falkentyne. Thanks. I followed your advice and did those settings.
Tested the "C" option and it failed after 7minutes (prime95 40k, error).
Option "B" passes the 12minutes threshold.
Ok I reconfigured for fixed voltage again
BIOS: vcore 1.35, llc 5, ac/dc 0.01, svid best case
HWinfo: VID in idle 1.210, vcore in idle 1.332
Will do the LinX test, but I am pretty sure that it will not be ok on 1.35
p.s. see the attachment, it is different on the third run...
1.35v was ok the first day, but now I dont know .. 1.37v was not enough in p95, 1.38 have not tried. That is why I decided to move to explore the possibilities with offset mode.
I dont use XMP yet. Just pure jdec 2133. First I want to get my cpu stable, then I'll deal with memory.
My dimms is in the QVL list - 2x16 gskill 3200 c14 ripjaws
Yesterday I had doubts about memory and tested with another 2x8 kit again without xmp. It didnt help at all.
About the avx or fma3 - I dont know - i think it is the FMA3 - see the attached screenshot - it is currently running.
Some years ago I also used the linkpack to validate max temperature, but I think nowdays the prime 95 is the most power and temperature stress test.
I discovered 40k ffts with many experiments with my previous cpus.
I dint knew about that method for evaluation of binning (vid on idle), usually i disregard the VID and use the vcore (or vrout) on GB board for comparing the cpus.
So at the end - my unit is just named KS, but actually is piece of sh*t 😞 ?
