Hi everybody, I have a problem with new revision (rev. 2.0) of Gigabyte Geforce GTX 1070 G1 Gaming 8G Windforce OC.
I built over 10 rigs with previous GTX 1070 G1 Gaming revision (rev. 1.0) and also other nvidia gtx 1070 cards (EVGA, MSI, Asus) and I did not stumble upon this problem that I am having with new revision from Gigabyte.
All previous cards had around 25-26mhs @ stock settings and around 30-31mhs with OC. This new revision has around 21mhs @ stock settings and 25-26mhs with OC. Tried with Windows 10 build 1607, Windows 10 build 1703 and Windows 10 build 1709 and also different driver versions (latest installed via Windows Update, manual install - 382.05, 382.33, 388.31 / everytime I installed new drivers I removed prevoius with DDU in safe mode) - no succes, I did not manage to increase hash speed, still 21mhs @ stock settings and 25-26mhs with OC. I have 6 same cards all perfoming the same so we can exclude that the error is on the graphics card.
Does anyone have the same graphics and the same problem and was able to resolve it...? I'm getting little frustrated, I have already spent two days and I can not solve the problem
I also called the supplier today and they told me that there is a possibility that manufacturer locked BIOS for mining performance, because they make other models (same chipset) for mining, but mining cards have 3 months warranty and these have 1 year warranty - I personally never heard that before...
Any suggestions would be highly appreciated...
