which memory straps are you using if you dont mind me asking.
I have a few hynix cards that cant get anywhere near those numbers

Gonna post them tomorrow, my rig is in a separate building.
Basically after some attempts, I noticed that overclocking and undervolting directly the rom is much more stable than doing it with softwares/claymore config.
The straps are self made btw.

I believe that I read somewhere that overclocking and undervolting directly the rom is not good (maybe from ethOS). It's great that you can test it.
I have one card accidentally modded directly to rom and it's stable but not good hashrate though.
Keep me posted, thanks.

Hey guys!
I just finally completed my first 12x gpu rig (finishing the second 12x one tomorrow), and I'd like to share my results to understand if they're good or if something can be improved.

The GPUs I used in the first rig were Sapphire Pulse 8GB with Hynix memory. I tryed different bios, made some myself aswell. At the end, that's what I got:

31,5 MH/s ETH and 475 SC (only eth 140W from wall, dual 150W from wall).
I'm using 1200 clock and 2250 memory, at 850v and 875v.
The temperature never gets over 62°.
I could run even 825v on memory on some GPUs, but 2-3 of them get instable, so I just set them all on 875v.
Out of the 12 GPUs, only 1 is giving memory errors (nothing but, about 5/minute), the other 11 gave 0 errors in 2 hours.

I'd also like to ask a thing, aren't those GPUs supposed to get about 100-130w on the voltage I applyed?

Comments and suggestions are welcome as allways!
