I did not know there was a precompiled version. What is the link? Only the 256 bit version gives this speed, I also compiled the 128 bit version and only get 60 Million keys/s. As far as the type of equipment I would like to keep the GPU type to myself for now, once I am sure it works and I find something then I don't mind. The CPU types are run of the mill I-3 intels
60 MK/s is probably right. If you only have 1 or 2 GPUs, I can tell you that speed on the version you compiled is wrong.
The estimate is, 256 V100 GPUs would take 46-60 days to solve #120. Each V100 gets 1500 MK/s. So with 256 the speed would be 384,000 MK/s so unless you have more than 256 of those, your speed in your compiled version is wrong.
Precompiled is here:
