So what're we at? I've been running my Thunder x3 for a while now, tempted to get some 8.5x8.5mm heatsinks and redoing the thermal paste. If anything I'm hoping I can possibly reduce the HW rate... I did some probing around, though it uses a different chip for line regulation, mine seems to be set at ~1.3V, though at the end of the chain, I was getting a 1.19V reading.
This is running at 344, showing 32.25MH/s (1.511MH/s Blizzard equivalent) with ~5% HW yielding ~30.5MH/s and the pool count reflects approximately that number. Typically I use 1024 difficulty but occasionally I use 384 when I feel I might miss out on the lucky blocks.
I'm using cgminer 4.3.5 w/zeus support. --zeus-nocheck-golden for decreased startup time/risk. Occasionally it doesn't recognize correctly.
Power supply:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182285cgminer 4.3.5 @ 344MHz, Win 7
Ambient temp 74-78F, middle of blade heatsink temp: 100-105F
Vc:1.3 to 1.19V end of chain under load (considering beefing up the connection from the beginning to the end of the chain)
Power draw: 1100W from the wall, verified. I might measure the DC draw later. If I upgrade/mod I'll run two 800W PSUs or something.
So, does anyone think I could reduce my HW rate by beefing up the heatsink/other mods?
