Does the brand of memory on gpu matter?

Can you get rid of the ATI settings entirely and set the GPU to compute with a third party tool (I don't think OverdriveNTool does it)?

Yeah, just unpack driver that you want to use, install said driver via device manager (RMB on gpu > update driver > browse my computer > choose path where you unpacked drivers (\Packages\Drivers\Display\WT6A_INF) > install)  or via pnputil /add-driver <\Packages\Drivers\Display\WT6A_INF\C0324065.inf> /install
Activate compute workload via registry ([HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000] 0000 for first gpu, 0001 for second, etc. key name is "KMD_EnableInternalLargePage"=dword:00000002)
There was a tool written for same task on this forum, but simple batch script will suffice, if you don't want to do in manually. I mean even simple reg file will suffice (example for 6 gpu):

Code:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]

Samsung is the best

Micron is the worst.

It definitely matters, but not a ton.  1 or 2 Mh/s if you bios mod them correctly for ETH.

Samsung cards are way better for Cryptonite, at least in my experience.

I had the luck of having 3 of my GPU's being Micron and surprisingly, they were all capable of being modded, in fact I had more trouble modding one of my samsung GPUs (which came OC by the manufacturer). The majority of Micron GPus that I have work just as intended. I only have a trouble with one of my Micron GPUs pulliing around 24-28 Mh/s , there's no work around for it - i've tried everything so I just have to deal with it. None the less I don't see Micron to be that bad.
