More than happy to host it for you until May 2012! Just let me know what you would like to pay (base this off of your current electricity usage, and I will be lower). The cabinet comes with 5Mbps bandwidth as well.

Sounds good. I appreciate the help.

Sent PM. Let me know if you are interested, since this is a *almost free* rental since I just want to get someone in there instead of wasting it on nothing. It is close to where you are, just on the other side of Point of the Mountain near Provo Canyon.

Can't really help you. If I add any more service to the cabinet (different voltage, bandwidth, etc) then it extends the lease term.

I have 90A @ 110V available, with 9 public IPs. I can provide remote hands/assistance. This is located in Utah. Please message me and let me know if you are interested - cheap rent (cheaper than the price of electricity)!

I have the whole 42U rack prepaid until May 2012 and just want to have someone fill it.

Utah, and I sold my systems to help fund an engineering effort.

Comes with up to 9 public IP addresses, .5MB/s throughput, and 90A service @ 110VAC! The cabinet is cooled and can house up to 42U worth of systems.

I had 6x dual 6990 systems in this rack with 1500W PSUs and it had no issue.

I can provide "remote hands" service to help get your system up and running with minimal downtime.

Please PM me (or post on this thread) if interested! I have this until May 2012 and am willing to give a really great deal to anyone out there since I am paying for the cabinet anyways! Think of this as having almost free electricity, which will give you more profit at the end!

Last full system that has a Silverstone has been saved to sell. I have another loose Silverstone PSU and will need to test before I can sell. I still have 6x systems that have the Ultra X4 PSU (I have not had many issues with this unit) in the HAF 922 case, 1x that has no PSUs and dual 6990s in a HAF 922 case, and a Cablesaurus case that has 3x 6990s.

Thank you! It was a lot of fun getting these together. I did have a rig that had 2x 6990s running with a watercooler kit from Koolance, but that was too much and the data center couldn't take a cooling kit unless I had my own suite... so I sold the kit and moved to fan cooled (A/C and internal).

I have 7 systems at the data center and can take those photos if you would like as well.

Send offers!

#haploid23: Ultra X4 1600W and Silverstone ST1500 1500W PSUs. Photos will be up this weekend. I am selling the parts on Reddit (http://www.reddit.com/r/BitMarket/comments/k9j6m/wts_6x_radeon_6990s_whole_system_or_parts/) as well and can be reached there as 'bahnfire'. What do you mean by references?

#trentzb: I have 7x complete working systems, and 1x more that has no PSU. I also have a Cablesaurus mining box/chassis (it is OK, would not buy a new one again since it has its own issues) that has 2x Radeo 6990s and a i7 950 3.06GHz Processorwith a EVGA X58 4-way SLI STX motherboard (and same 32GB SSD HDD and 2GB RAM), but that one does not have any PSUs as well.

They would ship from Utah (USA) via USPS/UPS/FedEx ground, and would have signature, tracking, and insurance. If you are within 300 miles of Provo, UT I can deliver if you would like.

I am selling several 2x Radeon 6990 mining rigs.

Specifications:
1x AMD Phenom II X4 810 processor
1x 1GB RAM
1x OCZ 32GB SATA II SSD
1x Asus M4A88T-V EVO USB3 motherboard (or equivalent)
2x XFX Radeon HD6990 video cards
1x PSU (1400W+)
1x HAF 922M ATX case

Systems all wired and ready to go. Just install Linux/Windows and get the miner software working! I have been using these for mining, but am selling to pay for some FPGA development.

Each system can mine around 1200MH/s (I never overclocked since I did not want to overheat the cards).

$1200 OBO. Paypal, BTC, and can list on eBay if you would like.

Video cards separate are $630 each OBO.

For the MSP430 code - what functions will need to be written (have not looked at updated schematic yet). What clock rates will the communication bus need to run at? Do I need to come up with a protocol, or will this be a community effort? How do the community envision the USB connection (CDC, HID, etc)? For the connection to the mainboard - what will the packet look like?

Sorry about the delay in replying back - I was supposed to come back Friday night/Saturday morning from vacation and ended up coming back late Sunday night. I will look over the multiple pages posts and will see if anything major changed and where we are in the design.

I am willing to invest some of my resources as needed - I have access to many supply chains and resources (my company has a factory in China and I can help purchase items from there). I also have a full test lab (oscilloscopes, testers, etc) and have contacts with many US and China PCB/SMT houses for prototype and production.

What I was saying RE: the extra pins was to take as many as you can and connect to individual test points not to just one. If you are working on a prototype this is the way to do it since you have easy access to pins if you need extras and will not need to do a whole new board spin (especially since this is a BGA). For production you can remove as many of these points as you can without sacrificing your future debug capability.

My opinion (and based on many years of experience): The goal should NOT be to design the first prototype(s) with the final dimensions (PCB size) as this will bit you later. You should always build a larger PCB that has all components and maybe a few extra items for testing to allow for easier debugging, dead bugging, and testing. Once the prototype is proven you can move to a smaller iteration of the PCB. Designs similar to this module could take several PCB runs from prototype to production.

If we do not do this we will run the risk of this adventure costing a lot of money and time.

Agree - but this can be taken care of by using a directed pour and many vias. I will need to gain access to the dropbox to check the FPGA routing, but you normall do not want to have long traces from the FPGA balls - you would just use a slight offset and a via to the GND layer.

I would change the unused pins to either be jumpered to GND or leave open with a testpoint/pad. This way you do not design yourself into a hole/corner.
