Polaris Bios Editing ( RX5xx / RX4xx ) - Page 27

post #261 of 3339
The PCIe issue was never a problem, just the media causing a tempest in a teapot.

Yield issues certainly could be.

I woud agree that the voltages are high to make sure they are all stable.

I dont really see much of an issue there, as anyone who gives a damn is going to tweak it anyway.

Which im sure wa there reasoning anyway,

This could be a yield issue to make sure the cards run without any stability problems. But we don't really know how many of them are stable at lower voltages so it's hard to say for certain.

There was also the PCI-E power draw issue which was promptly corrected with a new driver. With these two things in combination we would have seen lower power consumption numbers in reviews and possibly higher levels of performance.

There are also 8GB models masquerading as 4GB cards, this might just be to do with the stock levels of the 4GB models, so to stock more of them they used the 4GB bios on the 8GB cards.

AMD have released CPUs and GPUs with unlockable cores in the past, this time it's unlockable memory with the RX 480, what a bargain!

I suppose it's the same as any new hardware launch, problems are worked out and things improve.

One thing the XFX rep said on reddit was that the 4gb cards coming with 8gb could have been ones just needed to fill pallets for shipment. Hence why they just flashed the bios and slapped a sticker on it. I guess we wont know until we see cards that dont have 8gb on them.

AFAIK, only xfx and sapphire had 8gb on the 4gb, the others were actually 4gb.

Has there been any confirmation of cards that only ship with 4gb yet?

i havent hear anything from the owners of the other AIBs one way or another.
post #266 of 3339
4GB were very rare, now shops sold stock or just have some left overs of 8GB and waiting for the AIBs to arrive. You can buy the 8GB reference but no chance finding and getting a 4GB version, not in Europe, no chance.

I am just curious if anyone has successfully flashed the 8 GB XFX OC'ed BIOS to non-XFX cards. My card, which is due for delivery by Tuesday, is a 4 GB Sapphire reference card.

Ah so no WattMan thank god i hate it any ways. I love good old Afterburner always use it.

The reference 8 GB BIOS worked fine and dandy, but the Black Edition one gave an error. It stated something along the lines of "id mismatch" or something to that effect. I will post a screenshot shortly.

You need to use the command shell:
Code:
atiflash -fs -p 0 xfx.rom

Here is the fixed XFX Black Edition 8GB bios:
xfx.zip 111k .zip file

So there is 256k bios files as well. OP might need to edit. Or is that because of the file type being different?
