Anyone here mining with E5-2660 V2? They're cheap

Motherboards for those processors are relatively rare and expensive. Good mining chip, though. A full system would probably run in the $500-600 range, which means you would likely be better off with traditional graphics cards in profitability.

Natex still has lots of motherboards for this cpu

Sure, but...
s2600cp2j = $199
2660v2x2 = $240
case, psu, mem, heatsinks = ~$100-200
Total = ~$550-650

Which means that...

Put another way, this build would likely do ~1000h/s on Monero, while spending another $100-200 would get a Vega 64 (1800-2000 h/s) if you're patient. Aeon might be better though, plus you'd still need other stuff to light the Vega.

Better option is the Quanta gear, but those may or may not accept V2 processors, plus getting 240v power isn't quite as easy.

These things are dirt cheap at $113 each SR1AB INTEL XEON E5-2660V2 10 CORE 2.20GHz 95W PROCESSOR FOR DELL T5600 C8220 | eBay

RAM need 1 x 4GB per so that's cheap

Systems are cheap.

Is power high? They're 22nm right? They've gotta be profitable.
I put a E5-2660V2 system mining AEON last night. They are 22nm. This has 2x E5-2660V2 on a X9DRD-7LN4F in a SC846 with just a boot SSD. According to IPMI the whole system is pulling 244W and it is hashing 3075 H/s (1555+1520) with 12 threads per CPU. @funkywizard reported somewhere that he had achieved 3500 H/s with a dual E5-2660V2, but I haven't been able to match that. I haven't done a lot of tinkering with the settings yet.

Vega GPUs are killing CPUs ROI, profits

I have over 30 nodes miners using dual E5 v1 CPU.
Today, I am spending new investment with Vega card.
If E5 v2 is cheap as v1 CPU, I may upgrade the CPU to v2 to save power.

Are you using Quanta boards or something else?

Did you turn on huge pages? I'm also getting 3600 H/s with dual E5-2660V2, 12 threads each.

E5-2660v2 with 8 cores enabled will use the same power mining 3400H/s as E5-2660v1 with 6 cores enabled mining 2800H/s. Are your nodes compatible with v2's?

I've seen 3400 with 8 cores, 3500 with 10 cores active (uses 20w more power, so not worth it in my opinion).

Yes , the Intel nodes has support for v2 CPU. They still update bios almost every quarter for 3-4 years old hardware.

Actually, I am running a pair of E5-2650 v2 right now in one node

I found those to be really picky about mining configuration to get decent performance. Best I could get on Dual E5-2650v2 was 3350 H/s with all cores enaeld, which I was pretty happy with.

Personally I like the E5-2680v2 as it has the highest hash per watt and is a reasonable price.

Total system cost, the $/hash not quite as good on the E5-2680v2, but when you factor in power costs, the value of your time, residual value down the road, and the per-server cost of miscellaneous hardware, the E5-2680v2 is more appealing.

I saw your post in the other thread and tried using your docker settings to get there, but wasn't able to get mine higher. I just took a look at that system to verify no power management stuff was on in the BIOS. It wasn't, but I noticed the DRAM was running at 1333 Mhz. I'm going to check and see if that might be the issue later tonight.

sometimes it's fiddly. try adding or removing a thread to one cpu or the other. sometimes that helps, randomly.

also, if one docker instance is running slower than expected, restart it, and see if that helps.

In testing, I tried one docker instance per thread (real pain in the rear). first cpu, half the threads went super slow (20% below normal). second cpu, all threads ok.

I sorted the threads by speed, and restarted half of the slow ones. Checked speeds, all the threads on cpu1 were now running fast, even the previously slow ones I hadn't restarted.

Bottom line, the whole thing is fiddly. Sometimes all thats needed is to restart the miners.

The majority of the ram I own is 1333, so most likely most or all my miners are using 1333. So I doubt that's the problem. I did notice with monero mining, my servers with 8gb ram were more likely to need me to restart xmr-stak multiple times to achieve "normal" hash rates, compared to servers with 64gb ram. Maybe with low ram, the process is less likely to successfully pin the ram to the correct numa node? At least for monero, restarting the miner a few times (and checking if performance meets expectations after the restart) eventually fixes it.

It's all fiddly, so fiddle with it a bit : )

So I'm considering going down the CPU mining rabbit hole; any best practices for deploying to a large number of (EDIT: identical) headless nodes?

Eventual goal is potentially colo.

If you have less than maybe 1000 nodes, I'd just make each a docker host, then use the xmrig docker image deployed using a docker swarm. You could even use Portainer as the UI on a small node to monitor all of the hosts which is sick. With docker and swarm it's easy to push new mining images across a cluster.

I've been debating the 2660V2 and the 2651v2 with 12 cores and 30mb l3 cache

That looks good too.
