Yes.  Your's is Elpida memory.  GPU mfg made a common BIOS as the board might have either of memory and they didn't want to figure it out and load memory specific BIOS.

quick question.. after dumping my bios and launched polaris

my Asus ROG StrikeX RX570 Gaming has two types of memory

EDW4032BAB (ELPIDA)
H5GC4H24AJ (HYNIX_1)

is this normal ? GPU-Z only displays Elpida

Try this https://github.com/jaschaknack/PolarisBiosEditor for Windows you just need the PolarisBiosEditor.exe

It's Sapphire RX560 4g Pulse with H5GC8H24MJR memory .So it probably won't work or will it ?

Edit:tried timings from the bios you recomended didn't change anything still 11,8 MH/s

If it's a Powercolor RX 560 Red Dragon you could try this https://anorak.tech/t/powercolor-rx-560-red-dragon/35822

Hello, I need help with rx560 4Gb hynix memory. No matter what i do i can't get it past 11,8 MH/s. Tried timings posted here @1950MHz but hashrate was same as stock bios.
Thank you for any help or information

The issue was the UberMix 3.1 timings - that one card cannot handle them timings. Any suggestion to other timings I can use?

did you play with the TDP or power numbers?  What's the voltage and clocks on this particular card when mining.  most likely the card's throttling.

Hi Mattthev,

like many others I am new to mining and GPU OC.

Here is the situation:
Recently I discovered
and I actually have great success mining Cryptonight with zawawa's miner.

I mean a hash rate of 1,070 h/s for each RX 580 is not bad at all.
With Claymore's I never had more than 1,017 h/s, which is also not bad.
Ethash is working ok at 28.5 mh/s (Claymore's 29.2 mh/s).
If I understood correctly zawawa is currently implementing Equihash.

Anyway, with some recent release zawawa's miner became unstable on my rig (6 x MSI Radeon RX580 Gaming X 8GB with Samsung memory).
With v1.1.14 the miner stopped once a day (with i'm using right now with a batch in a loop because the monitor is not reliable).
But with v.1.1.19 the miner restarted 13 time last night (with the monitor working perfect).

To remove support requests (of my kind, I guess) zawawa does not support bios modded toward Claymore's any longer.
Which is fair enough.

Zawawa is doing a tremendous job answering all forum posts, bug fixing and implementing new features etc. all at the same time.
Therefore I belief zawawa deserves the 1% devfee and I really want to bear with him.

Currently my bios is modded with the UberMix 2.3 timing strap copied to 1:1500 and up taken from the source code of jaschaknack's PolarisBiosEditor v.1.6.4:

And the Good HYNIX_2 copied into 2:1500 and up (which was necessary I have learned afterwords):

Would you be able to mod the bios for my RX580 specific for Zawawa's miner?
If so, how many beer's would be required?

Cheers

I am new to this website but have followed and read some great stuff but I am stumped and wondered if anyone could help me?

I have 5 x RX570 Nitro + cards and have modded the bios for 2 of them, managing 29MHs. The issue I have is my 3rd card, with the exact same memory and bios, has a hashrate of 12 Mhs reducing to around 5/6Mhs. With no bios mod it manages around 24 Mh/s Any ideas?

I have used the same modded bios on all cards, then modded only the memory timings which also reduced the hasrate. I have also switched the risers and no luck. I am unsure why a bios mod kills the hashrate when it increases the other cards which are exactly the same

Hell what a brilliant thread.... One question how do I know which bios is which on the RX570 .... I believe  the silent one cannot be flash as a precautionary measure. ..Hence my question which is the starting point .....closest to front of the card or the position towards the middle. My Rx580 seems fine ...just need to sort the Sapphire Rx570 with bios switch.

Should I switch BIOS to silent on my cards before HEX flashing timings?
