Hi all

I'm trying to get me 2 sapphire R9 290 cards over 900 kh/s.

I'm currently at 890-895.  I just want to make 900  Grin

Currently running at

thread-concurrency 20481
I 20
gpu-engine 1015
gpu-memclock 1500
gpu-powertune 20

Temps are on 68c

I've tried adjusting everything plus and minus abit each way, but either says the same or drops.

It's the  R9 290 4GB GDDR5 BATTLEFIELD 4 EDITION.

I've been searching the net all weekend and trying different setups,   So far I haven't found anyone over the 900kh/s mark with this card.

1 trick I found was to remove the mounting plate which lets the air flow out the back quicker.  This dropped the temp by about 5c which in turn drop the power usage by 10w per card.

insignificant difference, move along, nothing else to do here but watch it hash.

Very true,  I will even be slowing it down a bit once I've done it.  I'll happily run at 850 day in day out because I know I can trust that to run 24/7


It's just the fun of the challenge
