Two GPU no SLI GA-B75M-D3H

[arnaud1241]

Hello,

I have a Gigabyte GA-B75M-D3H motherboard which doesn't support SLI. I am already mining Zcoin with a GTX 1060 and would like to add a GTX 1080 TI.

I have read that SLI is not needed as long as there is no need to pool the power of the cards together. Apparently the fact that I have only one pcie16x and other one is a 4x doesn't really matter as well for mining as the bandwith usage is negligeable for mining.

I am only wondering if you think there will be a lot of configuration to be done in the BIOS or anything particulary complex with this MB to do in order to mine with both cards ?

There is no additional BIOS configuration needed. Just make sure your PSU can handle 2 graphics cards.
With low quality insufficient wattage PSU you can blow up all your expensive system.

Thanks! One thing I have just spotted though is the sata connectors are would prevent a second card to fit in... I am afraid I would have to change my mobo and proc

Nope. Sata connectors would not interfere.
But your case (if it is matx form factor) might not be large enough.

The case is big enough I have just bought a bequiet : https://www.bequiet.com/en/case/pure-base/919 and it's quite big.

I thought it wouldn't fit not looking at the Mobo really carefully but after I paying more attention of a picture found on internet I think you are right !

I will make sure the PSU can handle it, I have a 500 watts but will upgrade to 750... I have 6 HDDs, 2 x 8gb ram 1.35v, I7 3770 3.4 ghz, 1 gtx 1860 and a gtx 1080 ti.
