Hey man what is your powerdraw like. I have a C7000 set up with BL685 G7 blades, with the same processor. You say you only run 9 threads out of 12. Do you think running all 12 threads will make a significant diff in wattage?
I'm trying to keep my wattage down, but still get a pretty high hash rate.
EDIT: Sorry didn't read your last posts properly. I'm a noob. How do you check your power usage and hash rate in XMR-STAK
Joel,
I run both the 6 cores, but with of the hyperthreads running as well, so the recommended config is 18 threads
{ "low_power_mode" : true, "no_prefetch" : true, "affine_to_cpu" : 0 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 1 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 2 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 3 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 4 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 6 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 8 },

{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 23 },
The 24 hour numbers are:
idle wattage is 144 watts
18 threads running:
mining 281 watts
24 hour run total wattage 6.95Kwh
hashrate average 817.7 h/s
hashrate/watt 2.94
Just started with running only the physical cores per Klee suggestion
12 threads

Initial numbers:
mining 263 watts
hashrate average 722.7 h/s
hashrate/watt 2.74
Estimate electric cost difference per month of $1.55
Just a note, I don't expect the hashrate/sec to change when I originally ran the 12 threads last week, it was pretty rock solid at that rate. So the 18 threads consumes about 18 more watts, for a .2 increase of hash/watt.
I am still playing around with the thread configuration a few hours on the weekend, but these older AMD opterons don't have a lot of wiggle room for tweaking.
I sat with my system hardware people last week looking at AMD Epyc versus Intel scalable processors for some upgrade projects, and got to talking to them about the my crypto mining rig during a break. They were pretty much in agreement, what I am seeing is the upper limits of practical configuration, without overclocking and sending power consumption thru the roof.
