XMR STAK's hashrate goes down :(((

[crazymagicmushroom]

Hi folks, I have an issue that could not solved for weeks and still trying. I have 2 xeon CPUs and 5 GPUs on my rig.

I am using XMR STAK for just my CPUs and the hashrate is around "1800 h/s" on CPUs with Xmr stak running only.

But The hashrate goes below "250 h/s" when I open EWBF or DSTM miner for GPUs and make them both running at the same time.

Seems like EWBF and DSTM consuming a lot of CPU but it doesn't mine with CPU!!!

Please tell me your opinion.

Thank you

Hi When I decrease the power limit of the GPUs my CPU hashrate is going higher.

So GPUs power limit effects directly to the cpu's hashrate

My power supply is on %50 load
