ARC A750 short run time

[eldritchdeli]

So I recently gotten the intel arc gpu (yes, i'm a beta tester lol) and was using the nanominer to test it's hash rates. I found that not overclocking the a750 goes to about 200w, hits 50.7 mh/s and is stable enough to last around a day without interference. I then tired to reduce the the power limit to 140w, increase Vm to +15 and increase the memory clock to +4 in the arc performance slider. It didn't even last for two hours before the system crashed. The gpu temps were around 67c and the vram was at 80c so temps weren't a issue. Is the tunning mechanism in nanominer causing the crash or arc driver instability? Is tuning the Vm an issue or tuning the memory clock?

So an update, I just used the power limit slider to reduce the amount of wats that the card uses, brought it down to 150w, crashed after 2 hours. I can now say for sure its the arc drivers, it's causing system instability even without the arc gpu installed. I'm also replaced the arc gpu with rx 580 and a rx 480 so the system sensitivity may be due to Polaris architecture which is a very sensitive and doesn't like other nvidia or even rdna 1 gpus.

Hi eldritchdeli,

I have also the Arc750 from Asrock OC variant, i used another mining tool, nanominer wont find my Gpu. But with the other mining software, i use following tweaks via Arc Control Panel and it works like a charme.

Watt down to 140 and GPU Power +50

With Watts you can go down to 110 too, and Hashrate drops down to 43Mh/s so no big difference. GPU Power same +50

GPU Temp is 56 c and VRAM Temp is 76c

Hashrate between 46 Mh/s and 48 Mh/s

@eldritchdeli did @Rom1122 's tuning work for you?
