Hi Jussi, after rounds and rounds of testing I stepped down to 141avx release. In short 12900KS is a King and 141avx is its GOLDEN throne for stable 7ECv2@1024 performance (no CUDA)
I have posted very detailed write up on my set up and tests here, important to mention that contrary to ordinary 12900K, i did not have luck with your custom kernels with 12900KS.
IMPORTANT EDIT
After a little bit of careful settings release - hqplayerd_4.33.0-145avx2_amd64.deb is stable as a brick and runs non stop for 12+ hours with mixed playback on 7ECv2 @ SDM 1024 / 1x: ext3 / Nx: hires-mp and FIR2/Xfi for SDM with exact BIOS OC settings mentioned in my post in CA forum above. No issues!
This is possible with manual configuration in hqplayerd.xml file for “engine”:
- multicore=“1”
- (manually add) nblocks=“8”
I say in combination with 12900KS - we have HQPe 7ECv2 @ 1024 golden standard from @jussi_laako !
