MSI GTX 1070 Aero 8G unequal hashrate

[Herb1030]

Hello guys,

At the moment I am using 6x GTX 1070 graphic cards. My system is Win10 pro 1709, H270 plus mainboard, 2x 750w corsair power supply. Graphic card driver version 390.77

My hashrate goes up and down, it isn´t running stable. I have tried different overclock settings. At this moment it is set to TDP 75% , core clock stock, mem clock + 600.

Here you can check the hashrate going up/down all the time: https://imgur.com/a/strgd


Thanks in advance for your help!

why are you mining eth with nvidia?

try  mining equihash  at 75% tdp 100 core and 500 ram

1. Mining ETH on nvidia is a bad idea.

2. Mining on Windows is a bad idea.

If you want stability and reliability you need to run linux.

I want to object this 2 point of yours. This with Windows 10 is only a myth now that only Linux runs stable. I have my mining rigs which if configured properly are running from many months without any restart (of course Windows update is disabled). Beside that Linux uses 5% more of electricity which can be another burden if your electricity price is too high.

Now to OP, +200 core clock and +500 memory is the max a GTX 1070 can handle with stable hashrate. While mining only ETH is not a good idea, dual mining ETH+DCR/SIA etc is a better idea compared to mining Zcash only.

Switch to 388.13 drivers and see how you get on. Found them the most stable at the moment for my 1070tis

Thanks for your help. I switched to 388.13 and also changed the OC setting, and it works better now. I only have to check where are the huge amount of stale shares from. I get about 8-10% stale shares. Rig is connected directly with cable (no wifi)
