I don't think: the strangest thing is that with the drivers up to version 18.3.4 everything works perfectly, the right white balance, perfect contrast and colors, even in the 3D it is unexceptionable. From version 18.4.1 panic, the contrast becomes unwatchable and I also have numerous crashes during the 3d benchmark!

I tried all the possible combinations of pixel format / color depth in display settings, same thing,some solution to the problem ?

I see some values related to gamma, contrast and brightness into amd driver windows registry key in: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4d36e968-e325-11ce-bfc1-08002be10318}\0000



the ones for my 590 and 19.3.2 drivers are:


AutoColorDepthReduction_NA = 1



ColourDesktopBrightness_DEF = 0 0 0


ColourDesktopContrast_DEF = 1.0 1.0 1.0


ColourDesktopGamma_DEF = 1.0 1.0 1.0


ColourFullscreenBrightness_DEF = 0 0 0


ColourFullscreenContrast_DEF = 1.0 1.0 1.0


ColourFullscreenGamma_DEF = 1.0 1.0 1.0


DALGameGammaScale = 646464


Gamma_NA = 1


StaticGamma_NA = 0


Edited: I also see more values related to it into:


HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\UMD



and HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4d36e968-e325-11ce-bfc1-08002be10318}\0000\UMD\DXVA



Are they different of the 18.3.4 values ones?.


I don't remember to see changes about the color / contrast with my 380 with 18.3.4 drivers. The gamma can't be changes with the driver now, but I don't remember when they had erased the option.

I bought 6 rx570s on Ebay, and it Looks like im running memory timings for ether, and the crytonight algo doesnt like it, got a lot of rejected shares which resulted in the IP ban from the mining pool, im Going to use Polaris bios editor, do I need to start with stock bios to do the tuning or can I just reconfigure the modded bios thats already on there ? As far as the 1 click memory timing goes, is that optimized for xmr only? Is eth tuning a different method?

Edit: Also I read that xmr likes low GPU clock high memeory clock? So 1150gpu and 2100 memory? I think my current tune is running a high GPU clock

Depending on the memory manufacturer, there are available public timings on Bitcointalk. Also, 1150 Mhz core is too low. Something around 1200-1250 at around 0.875-0.9V is best. Memory speed is depending entirely on the strap and memory manufacturer.

Hey. Can someone help me disable LLC in my bios? Cant seem to find out how to find the values. It's the last mod I would like to try but information is scarce. Bios is posted below.

Probably not a good idea to disable LLC due to transient spikes you can not see in software.

I've just increased LLC 1 level so see how that goes for you.

Guide here, if you want to disable LLC.

Thanks, I'm trying to fix a really weird problem with my card thats tied to the voltage. Basically if I use a 240hz monitor and play a game if the voltage peaks to a certain point the signal will go black. It's the reason why I'm looking into this, just trying to keep my card useful for a year or two until I upgrade. Thanks again!

AFAIK no.
Current status shouyld be UEFI yes - Secure Boot no.

Can you please tell me how? Maybe my bitlocker drive would work with just the UEFI ...


Thanks
