Ok.

New rom release, tighter timings.

Tests have been done on 15.12 drivers which i find are the overall best drivers available.
Also done a test on 16.4.1 and that's also ok.

16.1.1 & 16.6.* not. So if you have these, speed won't be the same.


Before, per card @ core 800 , speed Ethereum: 22Mh
Now, 23.5Mh.

Power draw, exactly the same.

Included a few roms in the package.

Link: -Here-


Greetings!

Thanks for sharing. I run the miner at 900/260 MHz, hash rate is 26.4MHz. I changed to the latest BIOS. There is no difference.

How are the memory straps? Is that every 125 MHz or something else?

Is that a ROM for the R9 nano? This is very impressive.

Thank you Satlite and Antantti for both of your help. In your opinion which R9 390 brand has that high asic quality?

It is all random. For my XFX 390, the ASIC is from 62 to 79. Mostly in the middle. The difference of brand should not affect the ASIC.

True, it is one big lottery.

Japinat, what is your voltage on those 62 and 79 cards under load?


I have a few. For the same frequency, the voltage on the 62 is around 1.00V, the 79 is 0.945V for 972 MHz. So 5% voltage, 10% power difference.

They go that low? Worst XFX I have is 76, need to take another look at them...


You are so lucky.  The highest  have is 74.7.

I have the XFX 1000, 1015 and 1050 cards. It noticed that 1000MHz cards have highest proportion of high ASIC GPU, the 1050 is lowest.

Have you guys tried the OP's 390 rom mod?

I haven't because I am happy with my 390`s @ -100mV. It is really easy though, just make sure you have cards with bios switch so you can always revert back if something goes wrong.

Hawaii cards with high asic quality can have default bios with up to -100mV compared low asic quality cards.

160w needs 0.97 volts and 960/1000 clocks, hashrate is ~27MH by then. Best cards do that with -100mV.

Is a there a rom for the xfx r9 390? I read that a few members where able to get 27.5 mh/s at 160 watts with the following settings .0977v 97x/1000mhz, was this achieved by just using trixx or a by a mod rom? Does the 97x mean 970 -979? Thank you for you help.

You have to use a BIOS mod to do that. Otherwise, you need to use the Trixx to reduce the voltage by 200 mV. But that will not get to 980 to 995 mV. 97x means 970 to 977.
