Speed with Intel Dual Xeon E5-2620v3

i have dedicated server with Intel Dual Xeon E5-2620v3 (12x2.4GHz) cpu,

i use windows 10 64 bit and nheqminer with supervoa pool,
my max speed is 18 h/s
is it normal speed? and is it good?

it doesn’t seem good to me. I would take the trash off your computer and install linux and see how that goes.

I get 14 Sol/s on my older 1st gen Xeon E3 12XX via 6 threads…for reference.

At work I’m getting 22 Sol/s on Xeon E3 12XX v3 via 6 threads.

Hell my dual core w/ HT 3rd gen i7 gets 10 Sol/s…


To get the most out of your Xeons for mining ZCash you must increase the memory.

I was getting like 16 Sol/s with a 12 core/24 Thread E5-2658v3 in each slot until I realized I only had a single 8GB stick in. Once I populated the other 7 slots for a total of 64GB I am now getting 130 Sol/s


if its memory bandwidth . quad channel only 4 time single channel on your xeon. from 16 to 130 h/s doesnt make any sence.

get some ECC ram already.
Mining using my dual 2650v3, got 50+H/s

i have 32 gig memory

@swminer26 wminer26 how i can use all of my server memory?

is there something wrong here? doing lscpu returns the following:

Only 4 cores, and 1 thread per core?

Its speed per CPU? or dual cpu server speed?

He had only 8 GB to begin with. With 24 threads, he might have needed more (but I thought only 160 MB per thread was needed which would be only 4 GB). But I think the problem was using only 1 of his 2 slots in the first channel. 8 slots x 16 Sol/s per slot = 128 Sol/s

23.5 Sol/s on old $215 i5-3770 desktop (80 Watt system)

I have on this cpu is only about 20. What the miner u using?

nheqminer xenoncat DDR3 1600 Mhz (“12800”). Ranged from 23 to 24.5 this morning while connected to nanopool. I think it’s a dell optiplex. I run it on 9 threads. 8 to 12 threads seemed to be about the same. I think the difference is that I have 4 memory cards at 2 GB each instead of 2 at 8GB. Ubutun 14 with the GUI running. I just turned it off via ‘sudo service lightdm stop’ (Ubuntu 14 but maybe not on Ubuntu 16) to see if that makes any difference.

For whatever reason, different sessions make different CPUs work better. Changes from 16 to 18.5 in old i5’s for no reason. Session can last 2 days at 18.5. Stop, then start, then it’s at 16 for 2 days. And vice versa on a different machine I see today.

Thansk, I have DDR3 1333, equihash very sensitive to memory bandwidth.

I have a xeon x3440 overclocked to 3.8Ghz from 2.5 and 4Gb of ram at 1600 Mhz(2:8) and i barely get 10Sol/s, should i add more ram¿?

Im getting 19Sol/h in total adding the hashrate of my gtx 560 (9 Sol/s) :frowning:

I have UBUNTU 16.04 Dual e5 -2650v2 2,6Ghz ( 3,0GHz) RAM 32 Gb (1866, but works on 1333) 2CPU - 2*8CORE -16x2 Threads - 35-40Sol/s per CPU

for maximise results turn CPU to Turbobust in bios
2650v2 (2.6Ghz nomina,l 3.2Ghz turbo mode, but ubuntu no set more than 2.999)
