Hi Guys,
I've just bought 6 RX580 from Sapphire (nitro+ 8gb) and I discovered that the memory is HYNIX.
I've played around for some days to achieve a good hasrate but unfortunately the maximum I've got is 25.2 / 25.5.
I've seen a lot of video on youtube, read tons of threrad here but when I flash bios and change some value on GPU clock or Memory I can't get more.
I read for the HYNIX memory the value to change on timings is the 2:1750 to 2:2000 and actually it's the only way to get more (instead of changing 1:1750 to 1:2000).
My problem is when I try to change memory clock (standard 2000mhz) every mhz up will be result on worst hashrate.
A good compromise is underclok the GPU (1066 or 1033 mhz) and undervolt it (-100mv) while the memory is always 2000mhz and I got 25mh/s on 95w.
Any suggestions?
Thanks in advance
Try 1625Mhz or even 1500MHz, but it couldn't work at all, try it on 1 card and only for 2000MHz. You could try some performance optimized timings, but they are hard to find. Best is UberMix but this one is only for Samsung.
Uh... 1625Mhz, on THAT Hynix (the shit kind rated for 2000 actual and ending in MJR) is not gonna work well. 1500Mhz timings are gonna suck worse.
