Very cool to see I'm not the only insane person who lays in bed at night trying to hash (hah!) this stuff out in my head.
Thank you for putting so much work into it.
It looks like the prices for the Wiwynn stuff has gone up and even the procs are looking like $70 each so I went for the following:
I got some 1U HP dual E5-2450L @ 1.80GHz.
Totals: 620.2 619.0 619.7 H/s
Highest: 629.1 H/s
They are running 150W full load.
4.13 H/s per watt.
2.00 H/s per $1
(all I had to do was install Ubuntu to a SDHC card I slid onto the motherboard and plug them into the kill-a-watt
(edit: scratch this, they are all dual slot cards
I'm seriously considering adding a GTX 1050 to get me closer to 1K. It should fit in the PCI-e slot just fine and I don't think it needs external power.
That should get me to 960H/s and
4.26 H/s per watt
2.12 H/s per $1
What do ya'll think?
