Anyone here with knowledge of CPU's and PCIe channel utilization? I ask because @Blackhawk67 over at the z.cash forum is claiming that he is getting an extra 70-100 sol/s per gpu out of his 1080ti's when mining with both cpu and gpu. Based on his post it looks like he is getting about 830 sol/s per gpu, but when just mining with gpu's he's back down to normal range. I suspect it has something to do with cpu and pcie channel utilization, but my knowledge only goes so far..

From the screen shots I see he is using nheqminer to mine on the
computer's CPU. IMO.
Is it worth it to use the CPU to mine?
Maybe if you have a spare one handy for replacement to restart your machine ASAP so
you dont lose too much hashing time.
Having a machine down for 3 to five 5 days waiting for a replacement CPU can be costly.
Direct link to external forum's are prohibited but an excerpt of @Blackhawk67's comment would have
been useful to form an enlightened opinion.
4x 1080 ti (GigaByte Aorus) + 1 1060 6G (Gigabyte)
Don't know how , but I've seen it "jump" even higher.
I'll try firing up a CPU miner and see what it does.
**edit**
Nehh, not the result I was hoping for. Could it be that my spikes are vardiff related?
Still a 200 Sol overall increase after letting "zcashd" do some mining.
