7990 Custom Bios - Remove Throttling

_lecro_ said:
Flash ok but absolutely refused to install newest beta drivers
had to go back to original before they would install.
I might try again tomoz but cant think what the problem could be.

W7 btw

If you have multiple monitors unplug them... (worked for me and a friend, I know it's odd and should make no difference).

Use UDD tool to remove existing drivers and then try and install beta.

What happens when you try to install the drivers?
 
OK so I seem to have run into a problem.

Matt, I added your BIOS to my card about a week ago, it seemed to go fine. Since then I have only played football manager 14 in windowed mode so it hasn't been pushed.

I have just tried to run Heaven and Valley and my screen goes crazy, I seem to have a loss of image quality and what looks like scanlines constantly going up the screen quite fast.

I switched back to the original BIOS and they run fine, although now I get a high pitched whirring noise when closing down a graphically intense programme.

Also (This is on the cards factory BIOS) Does this look normal? Why is the secondary GPU in GPUz showing 300MHz core clock and 150MHz memory clock when running anything? Also there seems to be about an 8 degree difference in temps on afterburner. Is this normal?

Any ideas please? I'm a little worried. :(

Things look pretty normal to me on those screenshots. Crossfire only works in full screen mode. The bios doesn't change anything that could break the card as it uses stock clocks and voltage settings. It merely enables the card to run without throttling, if you so desire.
 
Hi, flashed the bios and all seemed to go ok, restarted and installed the latest beta drivers but still seems to be throttled, gpu-z still stuck on 950Mhz and cgminer (litecoin) also stuck on 950. Any thoughts, is there anyway for me to identify its flashed ok?

Yes, can you adjust power tune to +50% in afterburner?
 
ah yes, just whacked that up to 50% and its now showing 1000/1500. So do i have to keep that on all the time or do i need to tweak it.

damn cant wait to watercool this hot mama next week, cant sleep with this mining all day like a hoover next to my ear lol.

So you have no idea why on your BIOS i get problems when running benchmarking software? Any sort of idea what would cause that?

Also I am running Heaven / Valley in full screen but according to the GPU-Z logs the 2nd GPU is only running 300MHz core clock and 150MHz memory clock unless I am reading it wrong.

Is there a program which I can run full screen which will show both GPU's current core and memory speed so I can ensure they both are actually hitting 1000/1500?

Sounds like a software/ULPS issue to me. Setup some overlays so you can monitor whats going on while running Unigine.

Right, switched back to the custom BIOS, uninstalled old drivers conpletely, installed the latest AMD beta drivers for this card. UPLS is definitely disabled and this is what I get on anything graphically intense. Have tried a few different things.

I have also noticed on Heaven/Valley GPU usage on GPU1 bounces between 70% and 100% and GPU2 stays stable at 100%.

On Saints Row 3 for example GPU1 operates at about 25% less than GPU2 :(
 
Right, i've flashed both rom's but i've still got core throttling on one core, it's going to 99% then down to 64% constantly when mining yet the other stays at a solid 99%, setting to 50%+ on boost doesn't seem to have helped either, any suggestions or should I be looking at a re-flash?
 
Matt, i have a separate question. I've looked at your custom bios, I just don't trust myself to get your bios thing right, and i don't want to be without a card if i mess things up.

Just wondering without the custom bios would increasing the voltage by 20% reduce throttling, with stock clocking speeds?

Would the 20% voltage increase heat?

What are some stable Clocks for the card with 20% voltage, without your custom bios?

BF4 runs well could be smoother though

I've been monitoring the usage in both Witcher 2 & BF4. both GPU1 & GPU2 Run at 60% - 50%.

My Specs ~

GPU: 7990 gigabyte

MB: MSI Z68A-GD65

CPU: i5 2500k 4.6ghz sandybridge quadcore

Make sure ULPS is disabled and try lowering the voltage to see if that helps. If not i will give you a different bios version to try.

If my above suggestion doesn't work try this. A new bios with a higher TDP limit matching a typical 7970ghz edition card. You still might have to use 50% power tune, suck it and see.

I don't think its possible to mess things up. It will either flash correctly or it won't. If it doesn't you have the second bios switch with the fail safe back up bios.

That said if you lowered voltage and ran with +20% all the time you should be able to manage stock clocks without too much throttling.

+20% is power tune. Nothing to do with voltage. It merely increases the power limit which stops the card from throttling.
 
ULPS is disabled according to AB, and dropping doesn't seem to help (i'm testing at stock clocks after flash which are 1000/1500/1200mv, i'm going to switch over to bios 2 and confirm it does it at stock, then try a re-flash from the start just in case it's me being a tool.
