so they should run 350 ok with stock PSU?
Thats what I do  Cool


lasted around 45mins on 350 then machine got SICK..... the pic says ALIVE but before i refreshed it did say SICK



Be careful, sick is something I used to receive before my GPU died totally

The power consumption depends a lot on ambient temperature. My stock PSU consumes 850W at night and 950W during the day.
Upgraded to the Seasonic X-650 Gold 750W, and day power consumption reduced to 870W. All at 350MHz.

850 W sounds like a lot for 3 hashing modules @ 350 MHz. This is at 120 V?

I am at 230 V and my default Batch #2 units with the 850 W power supply (enermax) pulls 765 W and the units I converted to a SilverStone Technology Strider Gold ST1200-G run at 735 W (92% power factor)

yes, 120V. There is a chance that my P3killawatt is off. I will verify with my FLUKE DMM.

To be honest I am thinking of upgrading from corsair AX860i to AX1200i so I can test oc settings in the 375+

The AX860i is rather impressive and puts out little heat.

Batch 1 users did you put new thermal paste? or are you running stock? I might want to add new thermal paste and maybe set the fan speed lower if I can get Temps under 45...

no new thermal paste here. Just upgraded power supply

I'm using Strombom firmware stable @ 11h 11m 33s 83647.44 @ 350 on slush Suggested difficulty set to 32 my temps are alot lower 46

Fans are not set @ 100% Fan1 2400 Fan2 3960 Fan3 3720


How did you change the fan setting from 100% to auto? Thanks

I flashed using Strombom firmware and just changed 300 to 350 and that was the define Fan speed
im using openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory_20130519b.bin

can anyone recommend replacement fans for  batch one?
I am interested as well. These look like they can reach 4000rpm max. Will buy a couple in case one fails.


what temps do your batch 1 normally run at on 300?

Is the measured consumption for 3 or 4 module Avalon? And what should be the recommended PSU wattage for 350 Mhz and 4 modules?

This is for 3 module avalon batch#2 black (stock 750W PSU). Just calculate the Wattage for 3 module to 1 and you know what it will be for 4 module  Wink

Hmm 720W IMO seems to be too much for 750W PSU in the long term usage.

I think 750W is output power of the PSU. Should be ~900W@Wall.

At the moment I calculate 720W@Wall with ~80% effiziency = 576W PSU output. Thats fine I think.

so they should run 350 ok with stock PSU?

Erm you are right. I haven't realized you measured it on the PSU input. My mistake.

325 should be ok on 750 psu?

There is 14% reserve, so that should be OK. But it depends on quality of PSU.
