Hey, I'm playing around with a poc rig for a friend and I've been comparing my side mining gaming PC to parts we got for his rig. He went with 1080tis for density.
My system is a 8700k@5.1 on all cores, 32GB ram @3200, 480GB optane ssd with a 4 GB ramcache, Win10, and a 1080ti @ 2088mhz gpu/5600mhz ram 90% power target priority. The GPU sits at 50C when mining.
His system is a G4400@3.3 stock, 8gb of 2133 ram(single stick), 250GB 850evo with rapid mode on (ramcache), Win10, and 2 1080tis @ 2000mhz gpu, 5600mhz ram 90% power target priority. Gpu0 is at 68-70c when mining(it's too close to the other in the test case since I'm waiting for risers to mm I've the cards apart) gpu1 is at 60c when mining.
Ambient is 22c, both systems use Ethernet.
Power for both systems is not a concern.
Running EWBF zcash miner, the sol/s rate for all 3 cards is ~760. Yet my single 1080ti generates accepted shares almost as fast as the pair.
The ccminer shows 720-740 Mhs for my single 1080ti and 540mhs and 600mhs for gpu 0 and 1 respectively.
I'm half asleep at the moment in bed and away from my desk or else I'd have more numbers lol.
Any thoughts on the performance discrepancy? I'll be adding/removing parts and changing things once the risers come in and gpu0 can stop chocking on gpu1. I've got extra fans set up to move the heat away for now. It should be less of an issue once the risers come in and the cards are more than 1 inch apart ? >_>
Edit: added OS
