The latest version 1.8.7 works perfectly for upx2. CPU is not overloaded. On the contrary on the same rig running at the same time srbminer and xmrig.

Will try it out, i used the 1.8.6 version yesterday. Otherwise i will use the "old_mode" solution.

Thanks a lot:)

I tested the 1.8.7 version and the "old_mode" method and in my case none of them helped. Still the cpu is at 99% and it's throttling my gpu's. With "old_mode" : true the hashrate drops even further, around 22kh/s per card. Is there anything else i can do?

Doctor, did you found out what's causing the cpu overload?

Nah, not really possible that with old mode enabled still 99%. Yes, hashrate is little lower on some algos with it enabled because more work is done on the GPU, and almost none on the CPU.

I exactly know why it's giving more load on the cpu, because upx job round is done in less than 100ms, and a 1,2,4mb scratchpaded job is done in ~2s.
Rewriting some stuff to use intrinsics, so cpu load will be lower. But still old mode enabled should decrease your cpu load a lot.


Fixed the issue, my config was not properly structured and it didn't initialize old_mode. Now the hashrate is great and the cpu workload is around 55%.

Great job doctor.



Currently i achieved to lower the cpu usage by around 40% without the old_mode enabled, still working on it, maybe i can lower it more.
Weak CPU + lot of GPU's in rig + low difficulty can really make your CPU sweat.

I am surprised that your cpu usage is 55% with old_mode, that must be some really weak CPU in there Smiley

Checked again after a while and it's down to 30-35%. It's a Intel Celeron G3900, the most affordable one for mining. Sold my Ryzens.
As far as i read this ann, there's a lot of improvement for Vega cards but almost none for the RX series. Is there any juice left for you to squeeze out of them or should i start considering buying Vega's now when they are cheap?
