Solved Rx580 Low Hashrate Windows Drivers

[KrazyJ]

I have a 6 card, MSI Armor 4gb rx 580 rig, using Claymore 10.2 I get 27-28mh/s in Linux, but I don't know Linux well and it kept crashing, I got fed up and installed Windows for the time being.  I get 16mh/s stock and up to 20.5mh/s modded, no memory errors.  

I am going to assume I have the wrong drivers, what driver works in Windows 10 best and if that isn't my issue any idea where to look?  I wouldn't be annoyed if it were 5% or so, but 25% is definitely something wrong from what I can find.

For Driver Crimson blockchain series Driver. If you try modded, What are the type memory your GPUs?.Use GPU-Z to determine the brand of memory. If you have Samsung/Elpida memory, you will want to copy the 1:1750 to 1:2000 OR. Those will get you much better rates than just copying 1750 down. For Hynix only has a different optimum setting for strap, clock, and voltage.

Mostly Hynix sadly, one Samsung and Elpida, I've got them all stable modded which is why I think it's the drivers.  I thought I installed the correct ones but I'll reinstall in the morning again.

Dowload the driver from AMD site :
Radeon Software Crimson ReLive Edition Beta for Blockchain Compute Driver - Aug 23

Also make sure you set Virtual Memory size in Windows at least 16 GB...More is better sometimes
Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory

Im sure you alreday know if you using modded bios on widows with newer amd driver , you need to use atikmdag-patcher-1.4.6

That's what it was, I thought I installed that driver to begin with but apparently something wasn't right with it.  

Yeah I used polaris, atiflash and atipatcher.

Hynix can be good ! Just need good timing.
