Group Buy : Arima 4 Socket Opteron Boards

I was wondering if anyone was interested in starting a group buy for some of these motherboards.

http://www.ebay.co.uk/itm/Arima-AMD-...tem5649db4df2I

should hopefully be able to get the seller down to $40 a piece for boards (maybe even lower) and if we buy in sufficiency quantity than the price for delivery of each one would be significantly lowered.

these are 4 socket opteron boards that take quad core barcelonas. there for they meet the requirements to do bigadv units. these will put out the same PPD as a GTX580 at lower cost and lower running costs . with processors,ram and power supply the total cost should come in at less than 200 and they use ~200w fully loaded with 8347HE opterons that cost ~15 each. the cost for the bare board will be about ~80inc vat.

you can read more about the boards here: http://www.xtremesystems.org/forums/...d.php?t=258619

Re: Group Buy : Arima 4 Socket Opteron Boards

Quite interested yes.

From the look of the threads its fairly simple to get running if you're not a complete novice at building stuff.

Let me sort a few things out and we shall see.,

Re: Group Buy : Arima 4 Socket Opteron Boards

They dont really fit in a case. the best way to mount the i have seen is on threaded rod through the mount holes. cardboard works equally well i have been told.

Re: Group Buy : Arima 4 Socket Opteron Boards

Ah, a good old "open" PC.. Nice.

I would probably try and botch together some kind of protection for it, cos the last thing I would want to to see it blow up along with one one of my cats.

Re: Group Buy : Arima 4 Socket Opteron Boards

FAQ
What is the warranty on these boards like?

These boards come with a 7 day DOA warranty from the supplier. There for I will test every board before it is sent out. I will then warranty the boards for 30 days.

Can these boards run windows ?

No, due to the ACPI implementation in the bios being geared towards Linux the references towards windows are incomplete, windows server cannot boot on the bare metal on these boards but it can run virtualized on a hypervisor like Citrix Xen Server(which is Linux at its core).

Where are these boards coming from?

Houston , Texas

How Will the Boards be distributed?

These boards will be distributed by me from within the UK, I will handle importation and testing when they arrive.

Is there a limit to how many I can buy ?


Within Reason, no

I need Processors and I am not sure what to buy?
This board Accepts Barcelona core quad core opteron processors with a stepping code of BA or B3. Avoid Chips with Stepping code B1 or B2 and “shanghai” core processors (Stepping code Cx). The chips with a B1 and B2 Stepping code will work but will lower performance due to the TLB bug fix (~20%)

What ram should I buy?
The Motherboards require ECC Registered Modules that are filled in pairs you do not need to fill every bank but doing so with matched modules will increase performance.

I don’t live in the uk can I still join in ?

Sure if you’re in Europe I will handle shipping as normal just with a small price increase. Otherwise I will make special arrangement to ship straight from the supplier.

Re: Group Buy : Arima 4 Socket Opteron Boards

Having a read on the folding forums and apparently some 24 thread boxes are now struggling with the latest bigadv units, not being able to finish them in time

Re: Group Buy : Arima 4 Socket Opteron Boards

I may have a way around that using Linux HPC but you would need at least 2 Boards and there is no guarantee it will work but people have done it with some sucess

Re: Group Buy : Arima 4 Socket Opteron Boards

Hi new member here, very interested in this board. Have you tried it yet? Have you still got any?

Would it work with the 6core opteron chips? If not whats the fastest quad core that will work in it?

I'm wanting to use it for Boinc WCG, is it even worth it? I mean vs a 2600k system for example, can be had relatively cheap these days.

Thanks Adam
