Polaris Bios Editing ( RX5xx / RX4xx ) - Page 63

post #621 of 3298
Try to backup your own BIOS and open it using PolarisBIOSEditor.
Start copying the memory timings from lower memory clock timings to 1750 and 2000.
Finally, save it and flash it to your card.
Always backup and save using ATIFlash.

I don't have the same card as yours.
So, try one by one and find the best timing for your card.

I was thinkig about that, is it going to work?, are there memory voltages included...say i copy paste the lowest timings from 1000 Mhz to 1750 ...but in the hex adress or how we call it, arent there numbers for voltage control ? Maybe it will be low voltage for such frequency ?

I don't know if it includes the memory voltage. But that is what people do for mining.
For example for RX 470 4GB they copied 1500 timings to 2000, for RX 480 they copied 1650 to 2000.

Does the voltage tables for gpu clock work on the bios editor?

I can get my card stable to 1400mhz with +30mv (gpu-z shows it running at 1.15V) (1.12V stock) Problem is when ever windows restarts it doesnt reapply the voltage. Or if the card plays and game then quit the voltage defaults back to stock which makes it crash next time you try play a game.

Seems like it would be a lot easier to just flash my overclock to the bios and be able to remove Trixx since it also causes a problem with stopping the fans if you close it.
Wattman refuses to work at all.

No voltage in VRAM_Info, even if you use hex editor and not polaris bios editor app. The polaris bios editor app is only selecting timings for you to modify.

the card must be "hardware" 8gb. You can't flash a 8gb bios on a 4gb hardware

Hello.. I have a launch day 4GB Sapphire RX 480 Reference flashed to 8GB and I want to overclock it a bit. Pointers in the general direction would be great.. I hear conflicting reports about whether oc'ing the chip or the ram is better.. AFAIK this is a bandwidth starved card so I am thinking of undervolting the gpu, increading the power limit to +50 and pushing the VRAM up towards 2150-2200? Some advice on how the ram performs at what voltage, and how far I can undervolt and OC the GPU would be great. Most articles on 480 overclocking are from the launch window and not worth a crap unfortunately.. ANd reading through this thread has been more confusing than it was informative..
what this post mean,its post 165 in oc thread.

Hello, i recently purchased a rx 480 too, and although i read through some pages here i still have some questions bugging me.

I noticed that if i clock the memory from 4075mhz in wattman to 4100mhz, the performance actually decreases, at least in the witcher where i tested it.
Is this normal behavior, i read that the memory timings change when you up the memory clock, possibly resulting in a worse overall performance, is this true?
Should i leave the clock at stock or up it a bit (to 4050-4075) as long as i dont get any memory errors (hwinfo)
