Have any of you guys played around with editing HBM2 memory timings on linux?
If anyone has a reference V64/V56/FE card with Samsung Mem on linux and is feeling adventurous, could you guys try the following timings?
--rp 10 --rc 45 --rfc 290
Please keep in mind that editing timings can result in damage to your cards.
These timings work for me on my Vega FE, but there's no guarantee they will work for other cards.
In particular, I'm curious what your cn trtl results are. Timings currently have a very limited impact on our other kernels.
any idea on the reason it can damage? heat?
I get 40+ KHs on VII on cn-trtl without the memory mods @ 1450 core and 1295 HBM2.
Do you know who manufactured your mem? I seem to have gotten Hynix, and I only saw 32 kh/s - Granted I only went to 1200, but the diff between 1050 and 1200 was maybe 2kh/s tops, so not sure how another 100mhz would make such a big difference.
