Hello,

My 750ti's are being a tad bit weird. I have 8 cards in total, 6 on a rig and other 2 on personal pc's (and my gtx 760's.) But we will just pretend those arent there.

I have seen some high overclock settings on these and im just not having any luck. The GPU on the Single card pc gets 2950mh/s,  and one Single card on the mining rig gets about the same. Running the rig at +80 +400 , all cards same OC. The 5 other cards are 2600 or less mh/s , and cant get them to come above that it seems. Temps are low around 43 degrees C.

I am using EVGA precision X, and on the rig tried MSI afterburner to see if that made a difference which it did not. I know not every card is exactly the same etc etc.

Any tips/advice  Smiley?

What algorithm are you mining?  Are those for X11?  I find that I get better total hashes if I run a separate instance for each GPU using the -d 0, -d 1, -d 2 etc options.  Are you running 1 instance or many?

Running them all on the same window. I can try sectioning each card out on its own ccminer35-50.exe thread tonight.



Last night 6/26 i took off all overclocks and am getting pretty much the same hash rate with lots more stability
