Polaris Bios Editing ( RX5xx / RX4xx ) - Page 44

post #431 of 3385
AMD seems to think high 80s are ok by their drivers. I know my card lost some oc headroom/needed more voltage over 85. I gained 10mhz for same voltage under 70 degrees. I mostly run in the 50s to 60s now under water at 1.22v

Edit: In game is much lower. I'm talking about benches.

Could anyone post a tutorial of how to flash RX480 OC bios on a normal XFX RX 480?
post #433 of 3385
Can anyone with a 470 see if the current 480 atiflash works with it? If you can also post the BIOS would be great to take a look at it!

Just got a 470 in...can confirm that flash tool works with 470, and this bios is locked down as well :/

First time poster here.

Just got a Sapphire Radeon Rx 480 Nitro+ 4GB card and I was wondering if it is possible to flash this to 8GB. The box has a sticker with the 4GB on it, and 8GB underneath, but I guess that is probably not a rule saying it is a 8GB card.

Anyone know if the Nitro+ cards can be flashed to 8GB? Anyone know which BIOS I can use (and where to find it)?
post #439 of 3385
I'm having black screen problems with my 4GB card flashed to 8GB when GPU is on idle state (300mhz core, 300mhz memory). It usually happens browsing web. Never has happened when I am gaming. Once after messing with power states GPU core locked into max mhz and seemed to be stable (memory did downclock to 300mhz though). I wasn't able to recreate that lock after reboot. I am using 4K@60 resolution with HDMI if it matters. Now I'm testing if black screens occur on lower resolutions. Occurs on lower resolutions too. I'm using crossfire.

Is there any way to overclock the idle state by a bit or force higher clocks for possible temporary fix? Wattman controls P1-P7 states, but NOT P0 state so it underclocks to 300mhz even though I set P1-P7 states to identical clock and voltage. I have also tried setting MSI Afterburner "force constant voltage" but it doesn't seem to work and Asus GPU Tweak II doesn't even have an option for "force 3d clocks" with RX 480. mad.gif I guess it could be fixed permanently with custom bios but not yet flashable? frown.gif

EDIT: http://www.guru3d.com/files-details/clockblocker-download.html This utility forces max clocks! It should fix this temporarily. Power consumption will be a bit high until there is a better solution though.

Lordkag's patched atikmdag.sys is working to allow custom ROM usage biggrin.gif , confirmed by @Eliovp .
