spondoolies-tech SP20 overclock

[vortexz]

Hi.Can anyone tell me how to OC the SP20 ?
Just got 2 of them, took me 2 mins to configure them, excelent working pieces of hardware
I have 1 SP20 that is run by 2x 1000W PSUs, and I belive there is some room to OC this one
Can anyone tell me the exact stepts I need to do in order to OC ?
Thanks !

... excelent working pieces of hardware ...

Thank you.

you are most welcome, I am very happy with your miners
Can you let me know how to OC the chips ?

you mayhave better luck in the actual spondoolies thread. generally speaking, you can do it two ways:
1) via the web interface - you can adjust the starting/max voltage and the peak power draw allowed per pcie connection (be careful over 250W, as you might burn up thiner wiring on some power supplies)
2) via ssh - this is more for in-depth tuning, and not for beginners

go to settings page set fan to 90
 Speed

Set your starting voltage no more then 10 mv under your stable working voltage (from ASIC stats page)

Start Volts Unit 1(0.64-0.80)  try .715

Start Volts Unit 2(0.64-0.80)  try .715

Start Volts Unit 3(0.58-0.80) try .71

Start Volts Unit 4(0.58-0.80) try .71

Set your Maximum voltage to 0.790 for maximum mining or less for economy mode
Maximum Voltage (0.580-0.790)  try .73

Set PSU power to 120 and let the system learn the actual PSU limit.
Max PSU Power Unit 1 (70W - 288W) try 235

Max PSU Power Unit 2 (70W - 288W) try 235

Max PSU Power Unit 3 (70W - 288W) try 235

Max PSU Power Unit 4 (70W - 288W) try 235

Save

check the asic stats  page  look for temps 115 and lower

If we talk about hashrate, what would be the result of these settings?
I have a EVGA 750w and a 850w 80 bronce PSU's.
Will this config assure me the most hashrate possible?
