Hey guys. Wondering if anyone could give me a hand on some issues I'm having.

-I'm on Win7 and I have 2 GTX 970s and I'm getting incredibly low hashrate of about 7MHs per GPU.
-I've tried like 5 different drivers including the 347.52 ones as well the most recent ones.
-I've tried both ethminer and claymore's dual miner on both nanopool and etherminer using both CUDA and OpenCL.
-Disabled SLI (completely froze windows until a disabled that).
-Finally I found out that there's a benchmark mode which I tried and low and behold I got 18-19mhs (which honestly is still quite low for a 1590mhz overclock, at that range i've seen people get 23MHs). But while mining it doesnt break 7mhs.
-Another oddity is only 1 of the cards overclock. Without an OC I'm at 1506mhz (base is 1506 as i flashed a modified bios a few years back to get more voltage) on the cards and with OC im at 1590. Either way only 1 card overcloks and the other stays at 1177mhz.
-Oh and I'm watercooled so temps dont leave the mid 30s celcius.

I've done everything I could find (which there isn't a whole lot of info, especially for my cards). I have had no issues in gaming or anything else. Overclock and everything else is rock solid stable.

Really appreciate any insight anyone can give.

Thank you.

Should give you a better hashrate, i configured a couple of GTX 970/980 a few weeks back for one of my friends, and we managed to double the hashrate on stock, running around 13-14MH/s, so with modded BIOS it should get you closer to where you need to be.

Hope this helps

Thank you.

I don't have the Optimize for compute performance option in nvidia control panel. Googling seems to say its for maxwell and win10. This is a maxwell card but im on win7 :/

None of the other suggestions seemed to work. Except perhaps the command prompt one. Both of my cards are now hitting the overclock clocks rather than just the one card. Perhaps coincidence but might help others.

I have the same 7 Mh using Windows 8.1 and single GTX 970 card. I have noticed that it is associated with EPOCH #. When mining with low EPOCH # I have decent 23 Mh, but for actual mining EPOCH #155 or 160 is set and hash rate drops to 7-8 Mh. I try to figure if I can control what EPOCH # is used but do not sucseed up to now.

This seems to be the issue. I tried epoch 110 in the benchmark and got 20-22MHs. I don't suppose epoch is something that can be changed in regular mining mode?

If not id love to hear of any others with 970s or maxwell cards that are getting normal hashrates.

PS: Using ethminer it says im getting 15mhs but i cant tell if thats for 1 card or both. In claymores it tells me the combined (which is around 15ish) but ethminer doesnt say.

Why not upgrade to Win 10. Last day to do so tomorrow 31/12/17!
