Can you tell us a bit more, about the rom?

+43.75mV VDDC.
Maximum TDP has been raised
Power limit has been raised
TDC limit has been raised
Fan profile adjusted
Slightly different timings.

So what is this rom exactly in terms of parameters - I thought it was undervolt one?

Check above..

Nope, this is not an undervolted one. With an undervolt it is impossible to reach +32-33Mh, let alone 38-39.. (Ethereum).

Do you have a version of this Bios that will work on a Asus r9 390 strix?

Your work is much appreciated!

Sorry i don't, as i don't own that card

Hi Eliovp,

I tried your ROM but it shows the same effect. I was able to change the core to 900mhz but once I started claymore's miner, the whole system crashed.

I really wonder why no other experiences this issue. What's your program to display your remote desktop? I use ultraVNC. I somehow suspect that the system still uses the GPU to render the remote desktop and causes the issue. Again, once I use internal graphics, no core/mem clock is shown in afterburner and I can't change the core to 1000.

Before I flashed the 75/75 rom, I just let it mine with the -100mv mem@800mhz bios and it worked @ 22mhz. Of course, I want to reach the 30mhz...
Do you think it can be due to asics quality?....

Talan,

From what i read there. (System freezing)

You have a power issue.

I've got over 100 Nano's, there's isn't a single one that can't handle 1000 core @ -100mV VDDC.

Obviously 800 core will run fine, it consumes practically nothing :p

If you raise your core clock, your power usage will go up. And not by a little, it will go up a lot if you compare it to 800 core clock.

So again, you're experiencing power issues.

How many nano's was that? 2, 3?
What kind of power supply do you use?
How did you connect your PCI power cables to your PSU? (2 on the same rail can cause it to crash..)
Have you tried just running 1 (1 connected to your motherboard "without a riser")?
What kind of motherboard is that? H81 pro btc? Molex connectors connected to the motherboard if you use non powered risers? Or if they're powered risers, than don't connect those molex connectors..

I can sum up so many things..

you'll have to figure out where it's going wrong mate..

Greetings!

Can you mod for an undervolt one - that is especially important for this power hungry r9 390?
