No custom milling needed if you just provide the right mounting holes on the board and position the chips correctly under the heatsink.

It is entirely possible to create 1.0v power supplies that deliver up to 120 amps with very little difficulty using polyphase buck converters. For instance, a 6 phase system need only handle 20 amps per mosfet/inductor, but once you have gone that far, it doesn't cost that much more in parts to have an independent 12-15 amp power supply for each chip.

I'm working on several designs as a part of a private BFL chip buy being operated for the members of the Eligius Pool. In the works are a modular design that can take from 1 to 8 chips, and an 8 chip board that is stackable up 8 boards for a total of 64 chips. The stackable boards will have per-chip programmable voltage control for over-volting/over-clocking. Chip cooling will use 2 CPU heatsinks so overclockers have the option to install water cooling or any other available CPU cooling system.

I'll be more than happy to provide fab services to any group buy that needs them. I expect to have pricing information within the next 2 weeks. Turn time from chip delivery to shipping is 3 weeks.

Up for your consideration is a Dell Rack with 4 chassis packed full of Dell 1855 blades.

The blades are a mix of 2.8 and 3.2 ghz quad core processors with 2g ram or more.
Some blades have SCSI drives, some are missing drive carriers.
Chassis are equipped with a mix of inboard 10M and 1G ethernet switches.
I have power cables that match the power supplies on the chassis.

This offer is for local pickup only and plan on bringing some help to load

I'm located in Dallas, Texas. Payment due at time of pickup.

Lets start at B5.00... let the bidding begin or buy it now for B10.000
"Auction" closes 6/7... pickup on 6/8

I've been asked to look into the feasibility of packing a core on to an XC3S50 and wanted to ask here before diving into trying to synth it myself. From what I've seen in the repo and this thread that device is probably far too small even for a tightly rolled hasher, but I'd like to hear it from the experts It doesn't matter how many cycles it takes per hash, just asking if it can be made to fit at all period. The person I'm asking for has some 500 of these chips sitting in a box

I had a similar problem with my dual HD7850s (OC 1090/1200 stock volts) -- I'm running BFGMiner and dialing up the "intensity" setting to 4 on both cards leveled the cards out at a higher rate than I was getting on the default settings (went from <610 to >630)
