Polaris Bios Editing ( RX5xx / RX4xx ) - Page 92

post #911 of 3451
hey guys, does anyone know what speed I could get my vram chips with a bios mod?

I have 4GB RX 480 from MSI and default clock is 1750 (7gbps effective). It says I have the Hynix vram modules on there, and I'm attaching the bios here.

People have been saying that anything past 1750 will change timings, is that true for these modules? I've tried 1930 for memory and its worked for a while if i add voltage to the memory controller and increase power limit. I haven't bench marked so I don't know if that is actually making my card slower.

Any help is appreciated.

Hello.
I have Sapphire RX 480 Nitro+ 8G, default 1342 MHz / 1150 mV maximum.
I changed DPM table in PBE at -75mV. After flashing bios, clocks/voltage settings was default (it's not changed). Why?
The new settings was applied only after pressing Reset button in MSI Afterburner or Strixx.
Then if I play with voltage in Strixx, card may be crashed. And after rebooting clocks/voltage is default (stock) again!! Why?? What should I do to clocks/voltage were always the ones that I setup in DPM?

I have to apply these heatsinks on rx 480 vrms, can u guys advise a thermal adhesive or something to avoid short circuit and also these are pure aluminium heatsinks so they are conductor.

Any idea how to set timings at higher than 2000mhz? Since I overclock the memory I'm gonna need to adjust the timing for that aswell. I need to add timings for say 2100, 2200.

Hi,

is there a way to bios-unbrick rx 480 reference ? I heard different, some say it only works with BLACKCAT usb.

I tried the paperclip method and i could reflash with ATIflash on windows 10 (the stock bios rom from the web, didnt saved mine) sucessfuly , but my card is still not working.

Here you goes . It's Arctic Silver thermal epoxy. Comes in 2 parts. You mix 2 equal parts and attach the sinks to desired spots. Give it at least 8 hrs to fully cure and after that they'll never come off. thumb.gif

Ok but one thing that im worried about is that. Is there any risk of shorting the card by applying these heatsinks because they are aluminium and any gud guide that shows how to apply? Im doing this the first time and i dun wanna ruin my gpu.

not unless you put them in an obviously bad spot, putting them on with thermal epoxy on the vrms and ram won't hurt anything Just make sure that's all they're contacting

I've been looking around this thread and can't seem to find one. But I have the RX480 Nitro+ OC and was wondering if there is an unlocked bios for it. Since I am putting it on a custom loop, I would like to be able to push it more than what is currently available.

Cheers

The Nitro 480 shouldnt be too locked down, also there is a bios switch you might want to flip to the turbo/not quiet mode. You can edit the bios your self its fairly simple with the tools in OP
