I have 3 GPU SKU: 11260-20 sapphire rx480 8GB, and so far I do not get any romantic modification to reach 30 Hash, does anyone know how to modify the blips of these cards with micron memories? Has anyone tried the insider procedure in this post? For this GPU model

A question reading the forum indicate that you should use an application in windows in any case I have my rig in ethos as would do to have the modified rom so that it reaches 30 hash? The modified rom is the one you already have published in this post? Can i flash?

Which of these would you expect to be faster? What memory/GPU clocks do you think are optimal? I'm running your 1750 straps, with mem set to 2040 and clocks set to 1025. Getting about 27.5-28. should I try the 1625 straps?

yes use 1625 straps will work fine Wink !

No, it 's a obvious sign of too much OC.
Hynix won't be stable over 1950 MHz with the common timkng straps.
Even with custom straps you are lucky if you can go over 2000 Mhz.
1950Mhz with 1500 timing should bring you about 28 mh/s.




ok so i have gone back to 2150 its stable now and getting 26.5-8xx 



how do i set custom straps   ?

u need to edit the bios first and looks like u didn't do that :S

UPDATE

so after setting memory clock to 2180 mhz and mv  to 1000, through WattTool   i could go to 27.1xx while having some screen flickering issues sometimes   if i overclock it 2200   pc crashes


should i ignore flickering issue ? is it normal ?

@insider00 - My stock bios for these cards is here
https://www.dropbox.com/s/84uznpkx3gpmt38/Hynix%20470%204GB%20Stock.rom?dl=0
Any help will be appreciated as the best I could achieve was 27.313 MH/s at 1950 Mem and a core clock of 1242 using the 1750 Straps.


@lazyboi - Post your bios and I can do some simple mem edits and can see what I can do.

after overclocking through wattman  memclock to 2000 and gpu clock to 1350 i get max 25.200 and temp goes 80+ (iam from india here temperature is 40C)

Eth received, Thank you.  I enjoy bios modding on my cards however it has always been a pain with some memory types. For example on rx 470 4gb Hynix cards I can't get them to hash over 27Mh but all my rx 470 4gb samsung cards hash at 29-30MH.


i think i can help u with the Hynix memory i have edited the bios before and getting 28.8XX, RX 470 4gb Smiley
