this is on a supermicro 8048b-tr3f..i just set affinity of each instance of xmrig to individual processor groups..suprising at 80% load the server is not screaming but i have added some dynatron r27 coolers inside..

What CPUs are in this machine? 900hash per cpu is pretty nice. E7-4809 v2 ?

no these are e7-8890 v4's . it will do bit over 4000 h/s if i turn up the intensity somethin like $14 day monero..i just run it at night when im not using the server

Ok, 60mb cache :) Thats a lot of cache... 20 threads. I get 600h/s with my e5-2680v2 that has only 25mb cache running 12 threads.

So, it really seems it's just about the cache. You have 1.6 times the threads... and almost 1.6 times higher hashrate. Your max peaks are almost spot on with the 1.6 more.

I think you might be able to get a bit more, as your max rates are so much higher.

How are you getting 600 on your 2680s? Mine have topped around 450 no matter what I do.

I have strange issue with x5677 CPU. One has Vmware installed, and a virtual machine with 6 vCPU has lscpu output,

And a single 6-thread STH container give me 300H/s.

Another one has Ubuntu installed on bare metal, lscpu output,

I use CPU 1,2,5,7,9,10 for 1st container, and 0,3,4,6,8,11 for 2nd container, but each only gives me 230H/s. The NUMA node CPU ID just look weird on bare metal.

Yes.

I took a few more stabs in the dark and got 580 h/s (1P nodes) with xmr-stak, 9 threads with 0-2 low power.

Got my hands on a dual Xeon E5-2667v2 (8 cores, 25MB L3, 3.6GHz all-core turbo)
Each CPU runs at around 710H/s, consuming a total of 305W for the whole system. It has 16x16GB DDR3-1866, so power draw could certainly be improved for mining only.

Try xmrig, it usually gives a bit more. And at least in windows, you really need to open the miners first thing when you boot up, to get all the available cache. It seems to be the magic trick in getting constant 600h/s.

And yes, if you got two cpus then you need to run two miners on both nodes and affine the cores.

~460 H/s is pretty normal for 5600 series processors. You could probably get ~500 if you ran bare metal without the vt-D.

I mine with X5660, X5670, and X5675. Currently ordered a bunch of L5640 ($10 each) to replace in all of my old servers, and then plan to sell off the X56xx series processors. You can squeeze out a bit under ~420 H/s for 2x L5640 @ 150 watts for a system.

I was able to get 500 H/s on the X5675 @ 200 watts. Running 2x xmrig processors affined to each cpu (0x555 and 0xAAA).

Code:
./xmrig -o <redact> -u <redact> -k -t 6 --av=1 --cpu-priority=5 --max-cpu-usage=9 --nicehash --cpu-affinity=0x555 &
./xmrig -o <redact> -u <redact> -k -t 6 --av=1 --cpu-priority=5 --max-cpu-usage=9 --nicehash --cpu-affinity=0xAAA

In Bios: HT off, C-states off, power managed - performance, turbo on, speed step on. (HP Dl380 G7, and Dell R710)

If I didn't get 300H/s on a virtual machine on same CPU (VM is assigned 6 vCPU and runs 6 threads xmrig), I would probably be happy with ~230H/s. But anyways, E-26xx v2 are much more efficient than X56xx.

There is no doubt they are more efficient, but they also still have a $200-$300 barrier of entry. And the E5-26xx have went up to $70-$90 a CPU for an E5-2660. Factor in a used chasis with psu or open compute, you end up spending almost as much as a regular GPU rig. The V2 is not worth the premium, you pay twice as much for an E5-2660 v2 vs the v1, and you only win about 150 extra H/s and 7 watts less, and also the hardware to run V2.

Or. Score a X56xx loaded server for ~100-200 locally. Dell R710 or HP DL380 G7. Strip it of the processors, strip it of the redundent PSU, strip it of the ram and RAID cache module. Sell it all off, you will break even or possibly make some money. And toss in 2x L5640, 2gb of RAM, and litterally pay just electicity.

2x L5640 / ~400 H/s / 150 watts isn't bad.

My Open compute nodes 2x E5-2660 / ~800 H/s / 150-200 watts. Obviously do double the hash for almost the same wattage, but again barrier of entry.

Tons of options if your electricity is cheap.
  • Go to an e-recycling center and get lucky like I have with 6 servers, strip them yourself and end up with some power hungry, but free machines.
  • Go the open compute route with E5-26xx V1 processors
  • Buy a pallet of Lenovo s30/d30/c30 and HP Z*20 (Dual/Single socket 2011 v1 only), much quieter than open compute but take up much more space
But in hindsight, with the latest RX 550 bios mod results (up to 500 H/s for a $80 GPU), and the price hike of E5 v1 and v2s on ebay. GPU rigs seem to make more sense, the viability of CPU based mining is extinguished come March/April - then you'll have to move on to a pumped altcoin mine it and trade it for XMR.

Can you post some info on this bios mod that gets 500 h/s from rx 550?
People are going to hate me as this is just as efficient as the Open Compute node fight club. Never talk about it ^^.

Not sure if I would derail the thread or not, but pretty much any RX 550 run through polaris with an undervolt, and 1500+ timing straps can get anywhere from ~450-500 when run against the Aug 23rd block chain drivers with sgminer.

Here is a shot of my 6 card rig. About ~475 on each card, with sgminer I get ~495 a card. But I hate sgminer with a passion it's so clunky and I need api endpoints for my daemon monitors.

Thanks for the info, i'm looking for a card for my desktop that could also mine at nights. And don't want to waste a vega for it.

This might be an interesting card, as it games enough fine for me and is cheap & has low power consumption.

Does anyone know how much does an E5-2650L v2 or an E5-2651 v2 hash? Considering these as alternatives for e5-2680v2 that does 600h/s, but are they up for it?
