May I ask what determines load? I have two Antminers,
#1 using cat5 connection and its wifi connection disabled has:
loads of 2.70, 2.56, 2.51,
hashrate 441.03,
DIFF 354,
Fan/Temp 3000/41 & 2220/41 room
Temp/Humidity 83°/-%;
and #2 at some distance running via wifi has:
loads of 1.62, 1.47. 1.42,
hashrate 440.80,
DIFF 367,
Fan/Temp 2040/40 & 1860/39,
room Temp/Humidity 80°/39%.
So the first has loads 147% higher than the second? Both S3's at stock frequency.
The biggest load is on an Antminer is cgminer, because it does all the work.
Installing the latest cgminer (which does NOT void your warranty) will, it has been shown, reduce the load by a significant margin.
I am actually surprised at your results, I would have thought the wifi connected antminer would have a higher load than the cat5 connected one, and that it would be reflected in the Diff that has been allocated by the pool, aka I would have expected the cat5 connected ant to have a higher Diff. Could you check your pool-side speeds and see if they reflect the GUI speeds? Also, what are the DiffR numbers for each? (PS. I'll expect a slightly higher DiffR on the wifi connected ant, assuming they are connected to the same pool)
Reading the last few pages I opted to install the latest cgminer on what had been the problem S3, #2. Before doing so I ran opkg list-installed | grep cgminer on both S3's so as to ascertain the present version. Both had 3.12.0-1. I downloaded the latest version on #2 and ran opkg list-installed again. Right now I'm guessing that installing via wget and rebooting doesn't update the installed listing as after installation of the latest cgminer the installed list still showed 3.12.0-1. Since that has the lower loads it could be the more efficient miner.
I will install the latest cgminer on #1 and check back a little later today.
The poolside hashrate show #1 to be lower now, GUI 438.38, # 1 having the higher load (2.46) and hardware errors. #1, cat5 connected, seems to have rebooted 22 minutes ago for no reason, now has a low hardware error count (of course only running 22 minutes) of 5, DIFF 449, DiffA 165394, DiffR 0, DiffS 0.
#2 poolside hashrate higher by 11.7%, GUI 440.28, wifi connected, lower load (1.39), DIFF 367, DiffA 6,986,294, DiffR 5505, DiffS 0.
#2 has new thermal paste applied yesterday. I'll be picking more up today and might rip #1 apart to change. Again, I'll download the cgminer to #1 and get back later with new stats.
