I tried your BIOS . But no luck. Video card does not start . Returned to the original BIOS. Maybe you can edit my BIOS ? Can I write you a PM ? (380x, Elpida)

I tried today also his BIOS, but seems he uploaded an unmodified BIOS. I get less MH than the original BIOS. Perhaps he uploaded the original BIOS by mistake.

Nah, i uploaded a modified one. Trust me.

Bios is modified in such a way that you need to set specific clocks or it won't make any difference.
I can however do so that the speed changes on any clock you set.

Read a few posts up.

I'll quote it.

I've tested Eliovp's rom on 380X (GV-R938XG1)

GPU shows 21.3 MH with an official rom
With a new rom I've got 22.9 MH (Memory Clock 1650)
Though the system is unstable and there were couple reboots and driver crashes.

I ended up with Memory Clock 1600 and 22.6 MH so I'm going to see GPU performance with these settings for a while.



So just set your core clock to 950 and your memory clock to 1600
To compare, set those clocks with the stock rom, run your miner. Flash your card and do it over. You'll see a significant increase.



To everyone else.

The positive thing (in my case) about sharing roms now and then, for free, is that i can do mods whenever i feel like Wink

You can send me pm's, i don't mind, i'll reply when i find some time, but it's impossible for me to modify each and every one of your roms.
That doesn't mean that i don't want to though Smiley Just need some patience.

Or... you could put one up for sale, as soon as i see that, i'll put one up for free  Wink


Greetings!

Eliovp BIOS works very well and it takes ~30-35w less power compared to stock bios ^^ Only thing that there is a unlockable 4 CU's so we need same bios mod for 380x cards Smiley
Rig is 2x 380x with Eliovp bios mod and 1 sapphire radeon r9 290x trix OC full with MSI r9 290x original bios(speed is same (31.6mh/s) but consumes ~20w less power.
