Is anyone using 8GB to mine this coin using 5 or 6 GPUs?
Just for your info, I do have two rigs, each running 5 x 1080 Tis and both Ryzen 1700 and Ryzen 1600 (stock clock speeds) run fine. But both rigs are using 16GB RAM.
Yeah 5 x 1080ti on i7 4770 using 8gb and I need more as I get memory errors if I push the settings too high, only 620 avg per card with 16gb would hit 660per card.
I was using 4gb but had insane throttling. If you have 16gb in both just try with one stick of ram out.
It was going to be difficult to test on those rigs because those are my "special" rigs - one is my personal desktop PC and the other is the PC connected to TV. I have 4 long USB lines coming out of the PC case for 4 additional GPUs. So lots of things are installed on those machines consuming more RAM.
In your case though, did you confirm that you are getting higher hashrates with 16GB?
Also, sounds like at least you achieved stable 620 hashrate on 8GB. Correct?
