Modded R9 390X BIOS for R9 290/290X (Updated 02/16/2016) - Page 195

post #1941 of 1994
minimum I can go is between 950-970mv @ 900mhz gpu / 1100mhz memory for mining stability. Still, it reads ~90w in GPU-Z and 180walls in the wall (system consumption already deducted).

I really tried to have it @150w but no go.

Still great cards. I wonder how to disable ROPS and stuff we dont need for mining.

Do you want to reduce power consumption or heat ? You want highest mining rate with minimum power consumption?

Send your bios.

yes max hashrate with min power

V1.8_gpu900_mem1100_vdcc1000mv_v2.zip 99k .zip file

This bios gives me 25.3 mh/s @ 180 watts at the wall. Under load it reads 978mv. I can do it with 938mv (under load) but it needs to be very cool and noisy.

I have settled with 840mhz @ 938mv 76ºc 32% fan for 23.6mh/s. Really quiet!




So I think the undervolt is already at the limit. The other way to decrease a few more watts would be to disabled ROPS. I think the_stilt made bios with them disabled

Do you have your original rom? Your hash rate is a bit low but silent that's good.

I need your original rom to speed it up & cool it down & reduce power consumption

Hey chris89 you really seem to know what's up.

Do you think you could get me going with a few BIOSs? The front page BIOSs on here don't work for me because I guess I don't have a reference PCB as I've got the PowerColor R9 290 PCS+.

If it's not too much to ask I'd love to see if we can get The Stilt's MLU BIOS/s working since I'd love lower VRM temps, but I've got Hynix BFR so I'm not sure if it's possible or not. Whether an MLU BIOS is or isn't possible though, could you also make higher/a higher performance gaming BIOS/s, and mining/a mining BIOS/s? (I don't know whether I need to try one or multiple so forgive the forward slashes)

Here's my current BIOS: CurrentBIOS.zip 99k .zip file where I made a slight change to keep the fans from going above 50%.
Here's some techpowerup info on the BIOS https://www.techpowerup.com/vgabios/161224/powercolor-r9290-4096-140226

Cheers. smile.gif

Thanks dude!

Is that an MLU, gaming performance, or a mining BIOS?
