A few GPU tests Sapphire 5xx. A few successes, but one problem.

I use:

Asus Z270F Strix - Without any problems, 7 GPUs work or MSI Z270-A Pro 6 GPU ready, I have tried, I currently operate about 10 Rigs without problem (RX 4xx)

SRBPolaris - BIOS editor
AtiFlash 2,74
atikmdag-patcher-1.4.5
Wattool o.92 does not function

Sapphire 570 4GB Nitro+ Hynix - strap 1750 - 1100/2050/-96mv-gpu/+20powertarget = 29,3MHs @ cca 156 on the wall

Sapphire 570 8GB Nitro+ Hynix - Strap 1750 - 1100/2100/-96mvgpu/+30powertarget = 29,6MHs

Sapphire 570 4GB Pulse Elpida - strap 1750 - 1100/1910/-96mv-gpu/+30powertarget = 24MHs @ cca 150-160 on the wall

Sapphire 580 8 GB Pulse Hynix - strap 1750 - 1100/2150/-96mv-gpu/+30powetarget = 27,3MHs @ Here I do not know exactly, a little more than 570, No more than 170

Sapphire 570 4GB Mini Elpida - strap 1750 - 1110/2040/-96mvgpu/30+target = 26,3-26,4 @ 164w on the wall = 169 USD newegg very nice

Sapphire 580 8GB Nitro+ - Hynix - Strap 1750 - 1100/2200/-96mvGPU/50powertarget = 27,8MHs

Hynix on 570 is better then Hynix on 580. Hynix on 570 timing 7777 @ 1750 but 580 hynix 999 @ 1750 but i have to check this because the problem is two different time sets 1: 1750 and 2: 1750 each for another set of memories.

This is my tests, But I have a little problem. The signature for the modified bios driver is ok. But it does not work at the same time 570 with 580 on one motherboard.

If the 4x 570 works and re-sign the driver, the 580 runs but does not run 570.

Simply, it works either it or it. It does not work together.

Does anyone have any advice or idea?

Maybe a new Atipatcher?

These numbers raise a few eyebrows... Can you please perhaps check the memory markings physically on the following cards and maybe take photos of the numbers:

Sapphire 580 8GB Nitro+ - Hynix
Sapphire 580 8 GB Pulse - Hynix
Sapphire 570 4GB Pulse - Elpida
Sapphire 570 4GB Mini - Elpida

Sapphire 580 8GB Nitro+ - Hynix - Strap 1750 - 1100/2200/-96mvGPU/50powertarget = 27,8MHs

A simple copy of the 1750 strap and I got up to 29.6 MHs in dual mode DCR with ver 9.3 at defualt DCRI - memory frequency was 2130 MHz and didn't even try pushing higher but I think it would go to 2200 for above 30 MHs.

So you have some errors in those numbers mate. Please redo your tests. Possibly you didn't edit the right timings so your scores are basically default timings with overclock

Expect much more from the 580 8gb cards. Please also tell us if the RX 580 Pulse radiator is bigger in size compared to its predecessor the Nitro without the +...

I have the same Sapphire 580 8GB Nitro+ - Hynix memory. Where do I find these memory straps to copy? Thanks for your help
