Polaris Bios Editing ( RX5xx / RX4xx ) - Page 267

I mean generaleramons Modded BIOS V2.1 (see first post) works fine with the today released AMD Crimson 17.4.4 driver. ;-)

Tested with "4k Optimized" Superposition Benchmark 3707Pt
+50-70pt more than Uber v2.3 (+2-3%)

I'm a bit late to the party, but I've got to say thanks for your work. Going from 2.1v to 3v increases bandwidth in OCLmembench from 239GB/s to 241GB/s. Valley sees a bit of an improvement as well, averaging out 3 runs it's roughly 30 points. Going from 58.9FPS to 59.7FPS.

EDIT: Superposition 1080P Extreme preset score doesn't budge at all, and I have no point of reference for other presets.

is like the timings of your system ram

777000000000000022CC1C00AD615B41C0570E152DCB7508006007000B031420FA8900A00300000010123A46B9354019

is a hex rappresentation of the vram timings.

https://docs.google.com/document/d/1CB8AtN0LhfR-kH0hi4pm6eMJfE3CNLLHB2bYt-nGpHI/edit?usp=sharing ( some test i've done to understand those values with ohgodadecode.exe)

you need a tool like polaris bios editor (or a hex editor and do it manually) to modify your bios and use those timings.

thank you for your answer,

how aggressive are those timings? is it gonna alter the longevity of the card in any way?
do they need more volt?

those timings work on any rx 480? (i got the sapphire nitro+ 8gb with 1306mhz boost) without errors (i mean errors like the ones from ram in memtest).

Ram voltage is fixed(1.5V ?). The timings are pretty aggressive so Max mem OC is 2100Mhz. usually 2030-2070Mhz. Timings can't alter the longevity of the card.
should work in any 8Gb card with samsung memory

last question: so "maxing" the mem timings is better than "maxing" the memory speed in terms of performance?

for example: these memory timings (but stock memory clocks) VS max memory clocks most of our cards can do in average = whats best?

thank you for your help.

it varies by card. Depends on the quality of vram chips themselves and the IMC.
I'm getting more bandwidth from 2125MHz + custom timings, than 2300MHz + stock timings. 241GB/s vs. 234GB/s. And then there's the added benefit of no errors; at 2300MHz I'd start to see slight artifacting.

the fact is that usually our cards can't do more than 2175-2200mhz without errors... so we overclock the vram only little and optimize the timings. It's usually better, because you need a 2250+Mhz mem oc to have the same level performance wink.gif

thanks guys, you are the best wink.gif
