Around 220000MB/s allows me to reach 16k Firestrike Graphics, about 400 points more from generaleramon best mix. But I see a lot of texture corruption: http://www.3dmark.com/fs/11869882

Next week I will do further test and try 1625MHz strap.

What all settings are you turning off in Firestrike...as your score is not showing valid since you used custom settings?

Just changing a few settings in firestrike and I easily hit 16k +++ with that said it is not a valid comparison, as I can get even higher by further changing settings for the run..

Just for comparison valid run with the same settings using the firestirke defaults to make the run valid.

No settings changed, only disabled physics and combined because I only wanted to know graphics score.

Cool beans then...but had to ask....now to try your memory timing strap And I also appreciate the work you have put into this. I just replaced your strap with the mine in the 2000 strap. Testing tonight and more tomorrow.

My early testing is showing good results but only up to 1425/ 2200

Previously any strap I tried other then copying the 1750 directly to the 2000 would results in many gpu memory errors at 2200. So far these are not showing errors at 2200. Tomorrow will be testing with what I play.

What are clocks at?

Do you guys know any cookie cutter ways to remove the memory bandwidth cap on the 480? I'm not really looking for getting the highest numbers in mhz on my card, just the best performance that it has to offer. I have the day one reference 480 with Samsung memory if that means anything. What's the best memory on these things anyways? This thread is just so vast I can't seem to find any concise information. Just a general point in the right direction like PBE setting would be appreciated.

Cheers!

Hi! I purchased from Amazon an XFX RX480 RS 4Gb videocard (RX-480P4J), now i try to save a bios by GPU-Z and AtifFash 2.7.4 but all time the size of bios is 256 bytes. What i'm doing wrong?

And, please, can someone give me a correct bios for my card to unlock +4Gb?

My bios: https://yadi.sk/d/W92NS0Z63F53nm sorry to have not a chance to upload bios here with error "AJAX response unable to be parsed as valid JSON object".

Thanks.

PS. Link to vendor site http://xfxforce.com/en-us/products/amd-radeon-rx-400-series/rx-480-rs-4gb-core-rx-480p4jfc6

Your card has Elpida EDW4032BABG so you can't unlock your card to 8Gb

Thank for you answer. I try to unlock 8Gb today by PolarisBiosEditor-master with change in bios file graphs: Size (Mb) and Density. After successful flashing bios in GPU-Z and other software i see 8Gb memory, but Radeon drivers didn't install correct and take an error when i try open Radeon Crimson software.

YOu need to patch the drivers with ATI Pixel Patch to sign the driver for use with custom bios.
