The funny part is that the E3 wasn't much more efficient than a well-tuned GPU rig - and if you have GTX 1070ti cards it STILL isn't (gtx 1070 has lost efficiency, you either lose 10% hashrate running at 110- watts or you have to bump power up over 10% to get back to 30 - GTX 1070ti has not changed), while being less efficient than some newer-gen cards.


I am in the middle of rebuilding all of my rigs, for a few reasons.
1) I am taking posession of a new place tomorrow - in a county that does NOT have a "cryptocoin-specific" ripoff electric rate.
2) The county I am in now did NOT have an issue with Folding@Home (and by extension Curecoin), so I had swapped most of them over to Folding for the last year and change.
3) Folding income has collapsed, due to the massive influx of new folders due to COVID-19 OVERLOADING their ability to generate work units.

An interesting factoid showed up in the process.

My GTX 1070 cards (still have a bunch of them DESPITE ever Gigabyte Mini card DYING) now need at least 122 and more commonly 125-130 watts to achieve full hashrate (about 30 Mh) instead of the under-110 they used to use.
At 106 watts they're mostly around 27 Mh - not horrible, but a noticeable loss on efficiency.

My GTX 1070 ti cards are STILL happy pushing 31 Mh at 106 watts.
I am now wishing I'd bought MORE of those....
