After reading about youngpro I had an idea.

[Movieman]

There are many thousands of you here at this forum who have recently read about our member Youngpro being diagnosed with Leukemia.
Nasty disease to get and to see this happen in one so young and full of promise is a sad thing.
As many of you know my passion in life is in doing medical research with the hope that the work we do today can help the next generation.
I also sit back and see 80,000+ members here but only a small fraction of those participate in the work we do.
I wondered why and thought on this quite a while.
Some think the work is useless as it doesn't give an instant response to the work done and I can understand that a little.
It's like building a house and we've just completed the foundation.
I also thought that many here aren't interested in or financially capable of having "electrical sucking, heat producing" machines running 24/7 in their homes.
I have an answer to that problem.
If you are capable of spending app $300.00( and have some common parts laying around) then read on.

A while back I happened onto a little system that intrigued me.
It was a dual socket server quality board that used what are essentially 2 Yonah laptop cpu's.
31w each and at 100% load run at 34C, draw 117w and can run quietly and generate essentially no heat.Even if a cpu fan failed it will run passive.
This is literally one of those systems you can sit on a shelf and forget it.
The problem at the time was cost. Server boards aren't cheap but times change.
I found a supplier for the boards at $29.00 shipped( Yes, $29.00) out in California. I've bought from them and straight to do business with.
http://www.centrix-intl.com/details.asp?productid=4675
The cpu's come in two flavors: 1667 and 2000mhz..
The 1667's can be found here for $120.00/pair:
http://www.itxchange.com/itxchange/p..._no=39Y6598-02
The special stepped heatsinks for these are available from OEMXS:
http://oemxs.us/shopping/index.php?t...oduct_id=29943 for $10.00 each plus shipping BUT they tend to charge $25.00 to ship 2 heatsinks.
The good part is that they are 19 miles from my home and I can do a "pick up"
I just recently grabbed 8 of them.
Last is memory, the board uses DDR2-400 ECC REG and thats available from Newegg for $72.00 shipped for 2x1 gig.
http://www.newegg.com/Product/Produc...82E16820134272
Now you will need a EATX case,and a PSU with 24 and 8 pin board connectors.
When complete you have a machine with app 60-65% the computational power of a Q6600 at 3600mhz.
mhz for mhz it is actually dead equal to the Q6600, just has 1/2 the mhz.
It makes almost no heat, runs dead quiet,is server grade dependable and it's cheap to build.
I have built two of these, one I sold to a member and one I have running in my unairconditionaed office.
I stuck a 36 gig raptor I had sitting around in it for the OS and I doubt I'll have to touch it for months if at all.
I use this on the WCG(World Community Grid) that does aids and cancer research amongst others.
If you want to make a positive contribution then this is a way that is doable.
Hixie here at the forum has started an account at WCG in Youngpro's name.
You can contact either he or I, or actually anyone in the WCG section if you have questions.
Thanks for reading.
Dave
Edit:
Here's a pic of the system. I call it 'Sammy" ..

The cpu's are technically Sossaman's so Sammy Sossa the baseball player came to mind.

Nice!! Great post Dave!!

Once I get a few things in order, I will be fighting for a cure.

edit: Those few things being a badly needed car, and a needed DSLR.

But after that, I plan on getting some cheap, low power crunchers (the mini-ITX, Intel Atom powered ones look attractive)

[hixie]

Where is the picture of original Sammy? That "heatsink" is a lot more attractive

The only difference is on the first one I used one of those blue plastic 120mm to 80mm adapters with the 120mm side down covering both heatsinks.
I didn't have the adapter on hand this time so I just screwed the 2-80's to the HS.. Same effect and actually same temps.
The one fan method is a little cheaper on the elec though in the long run..

[hixie]

That picture shows off the "heatsink" better.
Or should i say a very thin, finned piece of aluminium

Yes, agreed..and special to this board..has a step on the bottom to make it work right as these are a different height from the other duals.
Let me see if I can find the pic..

[Movieman]

Ok, here's some pics of the first Sammy:





and if you want an 'Xtreme" cooler for Sammy...

[hixie]

That's what i want to see! Almost passive under full load!!
The cheapest good looking E-ATX case i can find at the moment;

I have mine in this, a Lian LI PC62..EATX version of the PC60
Nice quiet stated class I think.
Not that great for a high heat system as it is just 2-80's front and one 80 rear but perfect for Sammy..
And not that bad in price now:

I bought one of these, plain crunching case Cheap and effective, well built

Now thats perfect and $53.99 shipped you can't beat!

Another one;
http://www.newegg.com/Product/Produc...82E16811215006
with the 250mm fan in front and the 360mm fan on the side panel i don't think you need a fan over the heatsink

HOLY CRAP BATMAN!
That thing looks like it's ready to take off and fly itself!
Yea, that you probably could run without HS fans..

Great idea, i have my ws at work folding 24/7, but happens someone use it and then shut it down

Lets fold for youngpro guys!

Easy solution.
A post-it taped to the machine saying:
DO NOT SHUT DOWN!
Medical research in progress"
Also stuck to the edge of the monitor will help.
If that doesn't then a electrical charge to the chair when the machine shuts down.
400-500v should do it!

Another option when the Sossamans run out is that Opties are going for as little as 50 a pair on Ebay. I'm getting DC Opties for my WA6 for 66 a pair, and the better ones aren't too much more expensive. A bit of searching and you can build a dually for close to that price.

Seeing as I'm benefiting from the research as well, I have no problem dedicating what it takes to the cause. There have been breakthroughs that can give me a new aorta, which would mean a natural lifespan, and a new drug that will keep me from coughing up my lungs-both of which mean I can live a full lifespan. That's not too bad, all told. Proof it works.

When my setup is live, I'll switch over to YoungPro's team. I have time, he may not. I'll give all I got.

The only issue with the Opties is heat and electrical draw.
This runs so cool that it doesn't heat up your house, draws like one 100w lightbulb and is so simple there's not much to go wrong.
Like I said, even if a cpu fan dies it will run passive.
Add in that the board is server quality and that this system was orginally designed to be in a 1U rackmount in an unairconditioned envirionment and it is a total winner.

If you would have started this thread now..

If you build a gpu crunching rig Dave, you will be cheaper and crunching faster... Most work done for science for the least money is the point of this thread? Then you can not dismiss Gpu folding imo.

There are some AMD based boards which can have 4 dual slot cards, and allot of board who can house 3. if you pair it with a cheap dual core and run vista, it can even feed four 280's ( or 3 9800gx's as the max supported gpu clients iirc atm is just 6 ).

That's allot of crunching power for allot less money needed to get it through the cpu in any project.

Edit:

I think I only adjusted the 'more science part' not the 'cheap' part.

Currently I think you can get a 8600gt for 50 bucks or so, and it will go in any running system you have already. That 50 bucks pos gpu will outscore most current cpu's which cost's allot more. My 90 euro's 9600gt I think would outscore your permawood causing intel rig, maybe that's an even more striking point to make?

Yes, but GPU's take a lot of electrical power and make a lot of heat.
This system is for the person who isn't your "average" cruncher as we are and doesn't want a high electrical or high heat system
This is for the average Joe or Mary to build, set on a shelf and forget it.
For that use it can't be beat.

[Marvin_The_Martian]

In that case, the high performance clients are out as they do require allot of attention

But, Angra measured his 9800gx2 at 43w per core I think, that's 86w in total for 9000ppd in Folding at home. Sorry I have to bring in points, but they should always reflect the science being done and we don't have any comparisons. Let's just say a higly clocked quad with dual smp is capable of 4500 max I think ( don't know, can't clock this high enough and thus run single smp for quick return times ) and that's about 3.6 or up. Kentsfield ( most would run with those still I assume ) will draw more at load.

Offcourse, compared to sossaman, it is still high, but considerbly less then I think most people assume. I though it would be the max wattage as defined by the manufacturer but the actual draw is allot less.

Edit: btw I should really change me saying my card would outscore your dually, as it actually wouldn't if you ran it tweaked. Though with just two smp's (instead of four clients) I would still feel capable of taking it on

That'll work

Or, if you want to get more creative there are plenty of ideas here

Nice thread, Dave.

[cabbspapp]

First impulse (sort of) system buy ever for me. I just ordered it and I already can't wait, I've never built a dual-socket system before.

Excellent! all you have to do now is to join YoungPro's sub-team and your destined for greatness
