@Klee Why dont you change to mining other coin instead of XMR? because as I have checked, sumokoin has better profit than XMR coin atm.
And I decide to buy a Wiwynn system in CN because it's cheaper and easier to ship to me.
Sorry for bad English
Are you running your nodes headless? Three of my nodes run headless and get the 945 number, the fourth node doubles as my desktop (I VNC into it, so it has an X server running, etc) and it trends closer to 850-900 h/s. It's a weird node though, since it's also a proxmox node and the deskto/miner are running in one of the LXC containers, which probably doesn't help.

For E5-2670 v1, I also see 975H/s
For E5-2660 v1 = 866H/s
You may want to double check which CPU in the machine?
Note that Windows assigns cores differently than linux on HT machines so this may be what's causing the confusion.@polyfractal - Interesting. When I run with your config I do get approximately 930H/s, still a little short of 945H/s but not very close to 975H/s that Marsh is getting, but certainly better then before.
The difference with your config is that i had my CPU affinity on even numbers instead of sequential.
I.E. 0,2,4,6,8,10 vs yours as in 0,1,2,3,4,5 so on and so forth. Not sure what the logic is behind that, but I had set up even numbers after reading one of the sample config files way back several months ago. Something to do with picking the physical cores vs the hyperthreads or so. Also, not sure why your config chooses to use threads 24 and 25 specifically with a gap in between.
I noticed with your config it pushes CPU #1 all the way and just a little of CPU #2. Wonder if that's intended behavior....
Now I guess it's time to tweak the whole lot.... Thanks!
The other thing that's helpful is to run two separate instances of your miner, affined to the cores of each NUMA node.Yeah, not sure either. I also tried fiddling with the config to do every-other and similar arrangements... could never beat the auto-configuration that does it (mostly) sequential. Really not sure why it likes this, or why it seems to prefer loading up one socket more than the other. Perhaps to minimize inter-socket communication?
It's been on my todo list to write a quick simulated annealing solver to see if the config can be optimized some more, but I haven't found time yet. I want to dig into the xmr-stak code a bit more first to see how it's using hwlock to determine these configs.
Glad it helped, goodluck!
Oh, interesting, even with xmr-stak? I knew you had to do that with xmrig because it didn't handle NUMA well, but I thought xmr-stak did NUMA correctly with it's affine settings.? Should I instead be running two xmr-stak instances each assigned to a socket's worth of threads (in my case, the relevant 8 physical + 2 HT threads)The other thing that's helpful is to run two separate instances of your miner, affined to the cores of each NUMA node.
Wow, I feel pretty stupid now. Thanks Joel for clearing that up!Note that Windows assigns cores differently than linux on HT machines so this may be what's causing the confusion.
Windows: Even numbered cores are physical cores (0,2,4...) and odd are HT (1,3,5...).
Linux: Physical cores are first, then HT cores. So for a 2x 2670 it would be: 0-7 (CPU0), 8-15 (CPU1), 16-23 (CPU0 HT cores), 24-31 (CPU1 HT cores)
How is temp on your E5-2651 v2?Wow, I feel pretty stupid now. Thanks Joel for clearing that up!
I think I've been able to increase hashrate another 15% or so at least, especially on the larger multicore procs like the E5-2651v2. from 750 to 885. Pretty significant.
HiBased on the $199 Quanta thread seems that was a result of Video output, I ended up ordering two of these Wiwynn i'll give it a go once I have them setup as headless, maybe try using PCI-e risers I have laying around.
I ended up going the transformer route, but even then I fear I will be maxing out my dinky 20A 120v outlet that is already powering my Home Server rack that has a pfSense box, an R710, and a GPU mining rig.
That magical outlet you found, is it a simple 12-2 single phase? Or is that a fancier 12-3 setup that was used for a Washer / Furnace?

Pools are gone tooA note for anyone thinking about mining Sumo: the only real exchange that I'm aware of for sumo is Cryptopia... which appears to be flaky at best. I deposited a few SUMO there as a test, and it still hasn't showed up after a few days. Seems to be a reoccurring issue with them, according to reddit posts.
So... eh. It may look more profitable on paper, but I'm leery of wasting much time on a coin which is only usable at one flaky and illiquid exchange.
I just recently found out about LiveCoin after having similar issues with Cryptopia (for some reason I'm not getting 2FA codes any more).A note for anyone thinking about mining Sumo: the only real exchange that I'm aware of for sumo is Cryptopia... which appears to be flaky at best.
