Refresh me on what speed these blades get and can they be over clocked?
FYI for anyone wanting to buy from Philip I have sent to him upfront and deal went very well...trusted seller for sure.

They can be overclocked (voltmodded) to 7MH, but will need extra care like heatsinks on the power mosfets, and another heatsink on the bottom of the PCB where the power mosfets are located. Secondary side fan to cool the power mosfets is almost mandatory if you want to reach 7MH. I reached 7.2MH on the ones I modded.
Extra cooling of each individual chip may help reducing HW errors too.

You can have a look at my topic for overclocking Gridseed Blade to 7MH.
Basically, overclock = replacing 1 resistor on each PCB and adding heatsinks and a fan.

Why not use escrow then?

at freq 600 they do 4.8mh

at freq 838 they do 5.5mh-5.6mh this is the max over clock

I will cherry pick from the 14 I have and send the better ones for over clocking.

My power footprint for the 14 blades is around 1200 watts. just under 100 watts a blade. with platinum psu's

I want to cut down to 800 watts to allow me to run a pair of s-3s.

a few photos of the farm. here are the blades

power used to run the system. it is all the fans the pc the monitor and 14 blades

shot of hashing note some blades do well at the 838 over clock
some want to run at 800 freq
I will pick out 838 blades for the buyers

I have 14 gridseed blades.
I have decided to reduce my farm down to 10 gridseed blades.
So I will sell off 4 blades.

I would take btc only.

I will pay for the shipping >

I would like.

0.4 btc for 1 gridseed blade.

My trust rating is good. > https://bitcointalk.org/index.php?action=trust;u=64507

no escrow.

you pay me up front.

I have usb2 for them for free.

I have power cables for them. That will plug into an atx psu. for free

I have atx psu for them. that would be extra.

Make an offer that is reasonable I can go a little lower.
