I got the 2630Lv2 chips for exactly those reasons. They are very cheap, low power use, and “good enough” clock speed to run GPUs. I don’t run any CPU WUs anymore.


I am beginning to feel price sensitive about my electricity costs. If I still want to run cpu Seti tasks will the cpu still run with less power at full cpu loads? I should know by Christmas if my operations change has dropped my electricity costs enough. If not, sounds like another reasonable step while still running 2 cpus would be back-grade to a couple of 2630Lv2 chips.

Yes I am confident with fewer threads and slower cpu speeds the cpu production would drop. But would it put me into a good budget place.

I could be wrong but i see no reason to use big CPU's and very expensive MB & cases to crunch, from all i know, a single GPU will do the same (or more) work with a lot less power and cost. Ian & TBar hosts are a live prove of that.

My 2 cents.

I understand that but every once in a while I get "cpu envy" and my 2nd choice Bonic project only does cpu crunching. Just thinking about a compromise between my cpu envy and my power bill :)

Tom M asked me to post with my config. This is my all-purpose Linux system at work:

HP Z820 (a beast @ 55lbs)
1125 watt PS
HP v1 motherboard (p/n 708464-001)
Intel C602 Chipset
2x E5-2620 @ 2.00GHz
Piles of ram
1 GTX 1070Ti
1 low-end ATI FireGL card, maybe a 3000.

https://setiathome.berkeley.edu/show_host_detail.php?hostid=8668207

Overall impressions, this system runs quiet, cool, and very reliable. It's running 24x7, been that way for months. It was in use as a video editing system for 5-6 years before I snagged it.

Ebay has a fair number listed, expect to pa ybetween 500 and 1000 USD + shipping for a dual-cpu config.

The power supply should support 3 dual-width cards, but I haven't had the slack time to give it a go.

The V1 version of the motherboard doesn't support the later E5 Xeon's. That would let me use some of the later lower-power cpus. Only noodling, haven't looked at the tradeoffs seriously.

What else would you like to know?

Kean

this is what I have currently.

AZZA 9000B case(a beast @ 60-65lbs as equipped)
Seasonic Snow Silent 1050 watt PSU(Enermax Maxrevo 1500w ready to go in, once I can lift this beast as I'm having surgery soon on My left elbow joint, I have a bone fragment there and it's very painful)
EVGA X79 Dark
Intel x79 Chipset
Deepcool Captain 360EX cpu cooler(idles at 30-33C, 45-55C when running)
3-Noctua Industrial 3000rpm 120x25mm fans
1x E5-1650 v2 @ 3.70GHz(this cpu is not supported by the bios, so 3.7GHz is the best overclock this cpu can do with this 2.14 Bios)
32GB Corsair Vengeance 4x8GB 1866MHz ram @ 1.6v(1.5v was tried, I got a b7 error as do others, so I took 2 out, rebooted, set ram at 1.6v in the bios, turned the PC off and inserted the 2 dimms I took out and it runs)
1-Asus GTX 970 Turbo
1-Palit GTX 970

Upgrades to come to the Beast(Pegasus):
Enermax Maxrevo 1500w psu(waiting on a shelf as I type this)
E5-2687W v2 3.4GHz(supported in the Bios) 150w instead of 130w
Alphacool ST30 480 v.2 Radiator(to replace a 240 in an Alphacool Eisbaer cpu cooler that needs some work due to a leak, leak since fixed)
3- PNY/Zotac 2080 Super or 3-2080 Ti Blowers(Zotac does not make a super blower though PNY does, if Zotac did I'd buy it, eventually)

I already have one 1500w installed in one PC and another will also have a 1500w psu, I have 3 Enermax 1500w Gold psus total.
