Modified GPU BIOS for Mining

[Ozzy1927]

I found a good deal on gigabyte 580 8gb gaming card 340$ each  and ordered 3 do you think this card can achieve 29-30mh/s even Hynix ?

Does anyone have problems in windows with weird clock speeds on custom bios cards?

I modded a Saphire 570 ITX 4 Gb Elpida memory to 1100/2000 clocks and 900mv, stable 24/7 in linux with those clocks.

However, in Windows 10, both with blockchain drivers and newest ones, sometimes card is clocked at something like 300 / 533 Mhz core with huge loss of performance, and I can't set clock speed manually with Radeon settings or MSI afterburner.

Huge PIA.

Anyone?

^^^ Try the new adrenalin drivers with compute enabled. Post your original bios I'll mod it with a custom strap and set the voltage/frequencies.

@notbatman

took the time and went through all the posts. Im hunting a bios for my Saphire RX570 Pulse ITX (mini) and did not found it here.

Here is my org bios:

tried like 8 different bioses on anorak.tech but nothing... The highest hashrate i could achieve was 25,7 eth and 450 on sia coin...

Many thanks for any help...

Here it is.... thanks for any help

Saphire RX570 Pulse ITX

I tried latest adrenalin drivers, same behaviour.

Anyway, this is a windows only behaviour. As I said, with Linux, core is always @ 1100 Mhz.

I'm satisfied with performance, 28,7 MH/s in ETH, not bad with Elpida memory @ 2000 Mhz.

is this result of 28,7 single mining or same result also for dual mining? Looking for some time for a working bios but nothing worked for me atm.... Would be grateful for any help.....

Single, but it can do it dual mining as well if you adjust -dcri in Claymore's.

Here is the modded bios I use now. Pay attention this Pulse ITX has Elpida memory.

hi there, sorry for the late response... Tried the bios you shared (many thanks for it). On the blockchain driver 23 august i got an error similar to yours but on the mem clock running around 533Mhz.... (instead of 2000) and on the 17.11.1 driver its the same like you described in your post with the latest adrenaline driver.... I tried it just on win 10.... If i find any working edition let you know Hope that @notbatman can fix it

Try this one

https://drive.google.com/open?id=1buFOCC3j87tw5U5809KLqxQUQPflHuiQ

It's 1200/2000, not so hard on undervolting, it seems not to have those strange clock issues in Windows.

It gives me 29+ MH/s on ETH.

As I said I'm not unhappy with performance, but power consumption optimization.

The card is more than stable @ 1100 core and 900 mv or less. No problem in Linux, but Windows drivers somehow mess up with clocks with this undervolting.

Thanks for sharing, finally some hope Im able to get 28-29 mhs an latest adrenaline driver, will test it a bit more and had also a funny experience with it on blockchain  driver where the flashed card where mining 75-101 Mhs (single!!!) would be nice but unreal....

I will test it more and will give you my feedback

Thank you very much for your help.

i got 4 rx 580 nitro+ 8gb and they all have Micron memory .I couldn't find a good bios for them can you help me?

[notbatman]

I need a mod bios for my rx 580 8gb card that came with my bios. I am getting close to 27mh on overclock was hoping closer to 30mh. I have Samsung memory. Here is my current bios:

HI,

Gigabyte Rx580 Gaming 8gb card with 1500 timing.
I would like to ask for help in bios mode.
I watched videos about it. Everywhere 2000 timing but i have 1500 timing.
I backup the  bios, and I opened it with the polaris  and one click timing patch. Changed from 24 to 25 mh/s ETH.

Driver: Win10-64Bit-Crimson-ReLive-Beta-Blockchain-Workloads-Aug23.

^^^ sure I'm going through them slowly now.

[notbatman]

OK I got 13 14 of them, any more requests?

14 bios request? Or what 14?

if so is the Saphire RX570 Pulse ITX included?

Ty for any info....

You can mod your bios easily with my guide https://bitcointalk.org/index.php?board=160.0 or with the one click timing patch in PBE 1.6
I also started my new store with mining bios that I slowly upload there... prices starts on 5 USD.

Why such price difference between models?
