Advice needed on modding Sapphire Rx 570 nitro + 4gb

[Golfmad]

I have been going through the forums over the last few days trying to work out how to mod my cards so that I can increase the hash rate from 22mhs. The problem is that no matter what I try I cant get the hash rate to increase, i'm probably missing a step and was hoping that someone here might be able to help.

My main issue here is that I am a little unsure as to what to put down for timings values. I have 2 sets (1: andd 2:) with hynix memory and so far I have copied 1:1500 to 1:2000 and 2:1500 to 2:2000. Is this correct for this type of card? As mentioned when I then flash the bios I see no change in the MH rate and Im stuck on 22!

Thanks for the help, been on this for a few days.

Did you reinstalled graphics drivers?

I downloaded the latest Crimson driver 17.4.4. Also patched the system so that the modded rom would be recognised. It is Windows 10 btw

For this particular card should I be copying both the 1: and 2: from 1500 - 2000? Still had no luck in shifting the hash rate.
