Wow, 180S/s? ? ? ?

And you ran the thing a whole 16 seconds? Daaamn man, that's some stable shit right there!!

Can't wait to try it out  

Not...

[mo35]

i understand thos are for 17-20G cards , in your opinion roms are ok to use for 01-20G OC versions ?

Actually that is in minutes if you know how to read Claymore's debug data

And here is after 56 minutes

I think you might have it wrong, isn't the "17-20G" a 200 Series Card?

This firmware if the Device ID 0x67DF which is the "11260-07-20G" SKU or "Sapphire RX 480 Nitro+ OC 8GB" I'm not sure what card the "01-20G OC" is.

Can you upload the stock firmware for your card?

What core clock is this running at?

[ps_jb]

Warning to all

I have 6 rx 480 Nitro+. My set has two different BIOSes. xxxx.X51 and xxxx.053

And in my case BIOSes for each card should be different

So dont be stupid just to flash your card with that one

This is normal if you have different SKU numbers, can you post the SKU numbers?

Cool, is this ROM the silent or oc version?

Cause this card should have dual bios setup.

What core clock is this running at?

The rom files say the Core Clock and the Memory Clock + Millivolts for Core and the Timing Hash (Last 6 Digits)

[mo35]

rom i posted is normal OC one (not silent) , one im keeping untouched.

[jadefalke]

does that really matter in what Slot you push a Bios (Silent/OC)?

It matter to you as preference, like, you might want to keep the OC bios stock so you always have it as a fallback stable option.

BTW, I checked the stock ROM that you uploaded, it seems to be non standard size, are you sure it's not corrupted? It's only 256KBytes and the standard size for the bios roms on RX 480s I've seem are normally 512KBytes

[Q_R_V]

It doesn't matter, other half of 512 KB bios is blank anyway.

Did not know this, thanks.

BTW, I think the smaller sized ROM is a dump from GPU-Z?

ATIWinFlash dumps a full 512KB version.

[ioglnx]

MY Sapphire RX480 Nitro+ DG5 OC (1342) doesn't even run stable  - fan is doing a low frequency oscillation noise very annoying.
ETH she crash fast and on zec in few minutes. Besides nothing touch just stock as she comes.

I think I will return it

Sounds like you need to get that RMAed ASAP.

Exactly, but if your gpu-z dump for polaris is smaller than 256KB then your dump is corrupted.

How did you undervolt it? I was trying all possible combos with PBE but no effect at all. A fellow member suggested Hex editor should be used to be able to undervolt within .rom. I intend to use it under Linux and there is no tool yet that can do manual undervolt(like Trixxx for example)
