extract your card's bios using gpu-z and open it with hawaii bios reader

make it look exactly like this:

save the bios and flash it

now open afterburner and in settings/monitoring set "hardware polling period" to 100 and close settings

then detach MSI AB hardware monitoring and make its window very big (like more than half of your screen)
now U have an @idle memory torture test biggrin.gif

then start UVing with sapphire trixx until blackscreen happens

shut down the system and switch bios using physical switch on your graphics card ( unless windows wont boot )
when windows booted up , shut down the system and switch bios to the modded one
(u have to this step every time U get blackscreen)

now set "the voltage that caused blackscreen+12mV" and fire up a benchmark like unigine valley
let it run for a while and if there were artifacts,BS,driver crash,etc.. start underclocking
if there were no artifact then u are so damn lucky and overclock the core

then start lowering power limit untill u got what u want tongue.gif

hope that helps thumb.gifrolleyes.gif

Hi,
I'm very interested in this... but I don't understand the Voltage Table.

Where do you find the voltage corresponding to each of your dpm frequency?
Is this voltage table in fact 3 voltage tables, each used for a certain asic quality? And i have to find out which one I use.

Can i change value directly in the "Hawaii Bios Reader" or do I have to fiddle whith the Hex editor?

Thank you

(for now I have only changed the offset value and fan curve in hex editor)

Since some guys have experimented with low voltages and refined your bioses, i want to share some things that you can do. If you put a 'middle' Clock that take care of the low voltages, you can run a high memory Clock on low voltage under load. I hope the Pictures explain this a Little bit better. The memory wasn't supposed to be at 1000 mhz at idle, i messed up since Hawaii bios reader messed up the clockspeeds with this bios, but this is just a Quick bios mod to show something that you can do. Notice the voltages and the clockspeeds. It made it through firestrike without a problem http://www.3dmark.com/fs/6411494.

So I update to win 10 and my CF setup is completelly broken.
FS is running very badly, clocks fluctuating like crazy, gpu usage too.....bahhh
im on 15.11 drivers

After upgrading to windows 10, it's a good idea to uninstall (completely) and reinstall the latest drivers. That's at least where I would start.

Thats what I did. 15.11 drivers are not working fine for me.
I reverted back to official 15.7.1 and all is good. Even better than on win 7.
Very pleased.

Clocks are 100% now.
Voltage regulation is awesome.
27500GPU points in FS! yay




EDIT://
it looks like its caused by freesync...

Ah, maybe there's a problem with 15.11 then. I'm on 15.9.1 with windows 10 and all is well.

I'm testing now and it looks like the problem is caused by "freesync".
If you enable it it's causing all this crap...rolleyes.gif

I'm confused about versions though. I did a clean install of Windows 10 and it automatically installed Catalyst 15.201.1151. Benchmarks are about where they should be, just a tad slower than the latest stable version I was running under Windows 8.1.

AMD Gaming Evolved tells me I should upgrade to 15.7.1 (stable) or 15.11 (beta). But CCC tells me what I have is up to date.

So, should I keep 15.201.1151 or go to 15.7.1?

If I do install 15.7.1, Windows won't think that's an older version and just reinstall 15.201.1151?

there's no need to change voltage under bios
just set a middle clock for memory and do the voltage adjustments with sapphire trixx

yes this is exactly what i came up with thumb.gifbiggrin.gif

my card just gets 1.01V under load biggrin.gif with -33% power limit and 950/1500mHz with a very very very slight throttling
but overall performance is higher than stock thumb.gif
