Hi All,

ATI farmer here, got 290s, 280x and 270x Toxic's in my farm. Sold off 7 rigs of 290s and 280x cards, replacing em with 750ti's, just want to touch base and find out the deal is with nvidia mining before I un-box all these lovely new cards?

Had some good success with under-volting and under clocking the AMD cards, do most of you under-volt the 750ti's?

I got each 280x down to 92 watts @ 3.93 Mh/s on x11, 270x down to 63 watts @ 2.7 Mh/s.

Took me a very long time to find stable clock settings and levels for under-volting, is it the same deal with the Nvidia range of cards?

Because they suck less power do most people bother with under-volting?

Until 14.7 came out, there was an inf mod you needed to get 6 AMD cards working in windows, same deal with Nvidia?

Got a nice stack of Giga Black's waiting for me to show them some lovin but I'm going to do my research first

Any help/guides/advice would be much appreciated Cheesy

Good news! Welcome to Nvidia mining.

I also had 280xs in the past which I also undervolted in order to save some precious energy. Sold all of them and bought the less power hungry GTX 750ti - 60 watt top, so really no need to undervolt them. To my knowledge people are not really undervolting these cards. Actually some are even increasing the TDP in order to be able to get all the juice out of this cards as it seems the default TDP is not actually at its 100%. I don't bother with that though, not worth it in my opinion and haven't honestly looked at it closely. We however OC those 750ti but the OC might vary on each algo. For example I am OCing my cards at +135 core /+ 200 mem (for XCN). I am sure I could OC the Memory more but I just don't want to lose time doing that I wont get much hash out of it anyways so I averaged the values and did a -5% to be safe. Depending on your brand/model you might be able to OC more or less. It's all about testing them.

As for having 6 GPUs on the same mobo, I have absolutely no problem with that and need no hacking of any kind in order for all of them to mine properly. I am running Windows 7 Ultimate 64x on a 990FXA-UD3
