Most of mine are running at stock, but I think it would be wise to underclock them slightly for the sake of efficiency. I think these are ok with running hot though, but I could be wrong. The exhaust temps are always high and I believe they were designed like that cause hotter slow moving air is easier to exhaust.
So far all of mine have a starting voltage of 0.69 and a max of 0.75. With that setting nearly none of them run at over 1600. Most run at 1550 to 1570.
I gotta get a 220v power meter or hook one up to a switched PDU and see what each one consumes currently at the wall.
What voltage do you run yours to get 1000 watts DC consumption? I think there is an efficiency chart SP-Tech published somewhere though.
Starting voltage between .685-.69, using wattage per loop to limit instead of max voltage. I would keep the rear two loops a little lower wattage to keep them from getting too hot. I think I had the loops at 265W front and 245W rear, I can't remember exactly. I'll see if I have a screenshot from when I had them running. I sold them all too soon with these last few cushy difficulty changes
I kept all chips below 100C, and fans @ 100%. I noticed a few percent decrease in power consumption @ given hashrate by dropping the temps by ~20C with fan at 100 instead of on auto setting. I do not trust the auto setting, keeps the chips too hot IMO.
That was quick teeGumes! Congrats, thanks for the easy transaction on the S4/Sp10.
