They sometimes have weird issues. Could be. I do know the official SR2PC spec for the E5 1660 V4 memory speed is only 2400Mhz. The official SR2PC memory spec for the i7-6850K is only 2400Mhz too. But my motherboard allows memory speeds up to 3333Mhz on Broadwell-E cpus. I am able to run the 6850K stable at XMP 3000 clocks and timings. I was never able to get the memory stable at 3200Mhz. G.

My almost 3yr old 3GB 1060's have an APR of 1300 GFLOPS while those 1660Ti's have APR's of 880.83 GFLOPS and 935.45 GFLOPS respectively. The 2 examples that I linked earlier on is what should be expected and they have APR's of 2,207.75 GFLOPS and 1,679.89 GFLOPS respectively (depending on -nobs being on or off). No matter what is the problem is, those GPU's just arn't happy (or performing up to scratch) for some reason. Cheers. ID: 2017105 ·

I once 3experimentded with 2 tasks per gpu but it never panned out, performance just didnt add at all. My 1660 ti's seems to be preforming quite well, it takes about 1:00 to 1:30 to do each task and actual RAC average is climbing dramatically since i made the changes above. my GTX 1660 Ti's show (just checked): i7-3960X Average processing rate 2,303.31 GFLOPS i9-9900k Average processing rate 2,341.84 GFLOPS ID: 2017903 ·
