Topic: What is the best way to compare PCs? (HP DL385 G7) (Read 106 times)

I have 3 HP DL385 G7 and I would like to compare them and see what is causing the differences between hash rates.

All are...
HP DL385 G7
Win10
8G Ram (4x2G 2Rx8 PC3-10600R-9-10-B0)
xmr-stak 2.4.3 3272f16
no other cards

Machine #1 - 6234x2 - last config line - { "low_power_mode" : true, "no_prefetch" : false, "affine_to_cpu" : 22 },

I want to compare machines #1 or #2 to machine #3 so I can figure out why the 6234 and 6238 are hashing at a higher rate than the 6272. What is the best way to approach this?

Thanks!
