OK for crossfire I had to back down clocks to 1310 sounds funny right that's basically 480 clocks of the original 1303mhz of the msi rx 480 gaming x 8gb well the results are fricken awesome! Better than a core i-7 4790k with sli 980's and i'm using a fx-8370 at 4.8ghz

After further testing, I decided to go back to 480 bios.

I've seen i can get 5-10MHz more with the same voltage and very high clocks don't artifact as much as before (I even managed to play GTA V at 1500MHz 1.25V for a few seconds).

But I see a small loss of performance in DX11, checked with firestrike (300 points less), Superposition (30 points less) and GTA V (0.5-1fps less). VRM temperatures are too high (+100ºC). Power consumption is broken. Core voltage is more inconsistent with spikes of +50mV and I see a bigger vdroop than with the 480 bios (1.156V while gaming and 1.18V with GPU-Z test with same MSI profile).

Hey, could you please open a TPU RX 580 .ROM file that you've tweaked with Polaris Bios Editor and post its screenshot here?
Because i'm really confused with some major differences between rom-s....

For the crash with relive, maybe try lower clocks. If it doesn't crash you might have a borderline unstable overclock, because relive uses some gpu to encode.

@robnitro Now i got more free time, give +20 Power Limit on Wattman and works now xD No crash nothing xD Thank you AMD, for this Free card by Download lol


Edit:

WoW my Vrm goes hot changing the Power Limit while benchmarking xD Before 72 Degrees xD

I think the reason I am not getting video after modding the bios fan curves and temp points is because my system is setup as UEFI only, modding the bios breaks UEFI?

Hi guys, i got a Sapphire Nitro+ RX 480 4gb with samsung memory and i seen that this model with samsung memorys sometimes are 8gb but bios locked? I modified my bios for 8gb and he loads well and shows 8gb but eny game i play that goes to 4gb ram simply crashes. Does it mean i only got 4gb or a problem with drivers? is it possible the Gpu-z telling me i got 8gb when in reality i only got 4gb and bios working like this?

I tried that too in the past as I have one too. It cannot be flashed to 8GB (even though the memory can be easily clocked over 2000 MHz), and no matter if you modify bios value to make it think it has 8GB.
Eventually, I removed the cooler and realized that the memory chips themselves (8 of them) are 512 MByte chips, i.e. 4 gigabit. Their code begins with K4G4.
