Mine has been hashing all night overclocked to 200 on the stock fan with no ducting and both boards are at 48.

how do you overclock? just received mine today

nevermind - figured it out. Next Q though, what's a good pool to use? I like btcguild, but not sure if the pps fee is a bit too high at 7.5% ?

Use PPLNS, only 2.5%

how much amp draws one blade, anyone clamp-measured that?

Around 250 through the wall for me.

Which advice? The part where I recommend not stabbing improperly sized and unstabilized terminals into high-current-capacity clips and trusting $1000+ hardware to it?

No, the potentially fatal advice that 12V (80A) isn't dangerous.

That's the plan. I would never sell it like it is, this was just a proof-of-concept. Currently finding and pricing insulated blade headers. I need to do a bit more testing to get it fully ironed out, but the final should have a daisy-chain option where one power supply will turn several on and off together. Also screw terminals for mounting your own wires, instead of cables hardwired to it.

If you mean something like this, I haven't quite finished inventing it yet. This is a prototype for driving two Cubes; the final will have screw terminals for hooking up whatever leads you need. If anyone's interested in something like this guy, let me know and it'll spur development a bit faster.

As a note, the 750W Dell supplies run about 90% efficient (http://www.plugloadsolutions.com/psu_reports/DELL%20INC_Z750P-00_750W_SO-81_80+_Report.pdf)

make a cleaner version that has a little bit of shielding between the terminals, and i would be strongly interested in 1 or 2 of them

Well, except it's at 12V which doesn't do much to skin; OSHA doesn't require gloves until 24V and those guys are freaking safety sticklers.

But also note this is a prototype for my own use and the final design will be a lot more enclosed.

Why I'd worry more about his terminals though, is because spreading those clips too wide by jamming crimped connectors in them could cause shorts a lot easier than using properly-sized blades, and because there's nothing except friction to keep one or more wires from popping out which would cause a current overload and fire hazard on the remaining lines. That's scarier than anything I'd recommend for anyone. What's demonstrated in that picture is a lot more likely to short or burn than what I have currently running, and a lot more likely than my final product is gonna be.

Its nothing to do with the voltage, holy shit. That current is seriously dangerous, as is your advice!

Nothing, yet. Just monitoring temperatures and refining the design; been running two high-clock Cubes for 10 hours straight now and nothing on the board is even warm. Obviously the final product is going to be more enclosed/polished.

I think the picture Crover posted looks a fair bit more dodgy. Looks like they just crimped some 1/4 quick-connect tabs and shoved them in place.

His the terminals are shielded from each other, yours currently could short SO easily. Touch the wrong spot and you'll have 70A go straight through you.

I should have a completed PCB design in the next couple days, need to find a reliable/affordable source for the blade terminals. I'll definitely keep you posted.

Also definitely looking forward to the next GB of these guys, I just barely missed the last one.

let me know when you get the final product up and running as really needing to sort out my power solutions.

Thanks

That looks quite unsafe, like a huge fire risk. What are you doing to prevent that?

Hi,

Looking to switch over to the DELL server PSU, can anyone tell me where to get the cables as shown by other users ?

Thanks

Link to a picture?
