Hello everyone,

I have 6x XFX RX580 8GB all with Hynix memory. Out the box they hash at about 22.1-22.7 MH/s. I updated the drivers to latest. I am testing two cards in my gaming pc until the TB-250 gets here. I have tried to under-clock the cclock and it does not affect the hashrate so pretty sure I'm good there. But in trying to overclock the memory, I put it up to 2050, and I drop to 19.5 MH/s. Only on the first card, GPU0, the second card typically doesn't get affected. I am doing this with the AMD settings desktop app. I tried also with MSI Afterburner but same results. Played around with under-volting and got decent power consumption drop.

Finally I patched the drivers, loaded up ATIWinFlash and modded bios(flipped switch on GPU toward rear) by copying the 1:1750 timings to the 1:2000 timings. Saved and loaded and still same hashrate while same situation as far as overclocking while dropping in MH/s rate.

If anyone can help it would be greatly appreciated!!

22MH/s for stock is possible, it should be more like 24Mh/s, but it could be also the motherboard, TB-250 will push it more. Hynix is the main problem, but you should be running at least 28MH/s with good timings. PM me if you want it.

Why the MB TB-250 will push more hash?
