Title: Second gpu is slower than the first one. EVGA Gtx 1070 OC Post by: MatrixCoinMining on December 03, 2017, 07:57:30 AM Hi everyone ;D
So i'm relatively new at this mining journey.. :-\ If i use 1 gtx 1070 (GPU0) it has a hash rate of X per second, then the second gpu is about at least 30% less sometimes 50% less or more. I tried with ccminer, nicehash, awesome miner, and some other tutorials i found before. It's always the same problem. I also tried switching the gpu on the motherboard but it's still the second one that's slower (GPU1) Any idea what could cause this? ??? This is the settings i see: Quote GPU_FORCE_64BIT_PTR 0 GPU_MAX_HEAP_SIZE 100 GPU_USE_SYNC_OBJECTS 1 GPU_MAX_ALLOC_PERCENT 100 GPU_SINGLE_ALLOC_PERCENT 100 Awesome Miner Diagnostic Quote Starting Diagnostics Starting Mining Software Setting up Miner Engine.

Although, mining Bitcoins with GPU are hardly profitable anymore your profit will be gone for electricity costs, I suggest to try your luck at altcoins instead.

If with all these other miners you are getting the same results try changing the PCIE configuration to X1 in your motherboard BIOS. Title: Re: Second gpu is slower than the first one. EVGA Gtx 1070 OC Post by: gt_addict on December 03, 2017, 12:04:44 PM I have a similar issue but my third 1070ti would cause the system to restart. Had to clock it lower than the first two.

Code: setx GPU_FORCE_64BIT_PTR 0 second insert your second gpu to x1 slot nearest to the cpu and first gpu in x16 slot third set the same clocks for both gpu and set the intensity -i 21 in miner bat file |
