Since I won the Antec Three Hundred Two case and the Antec 750W High Current Gammer Series power supply, I have been thinking of builing a 2P folding machine. I currently have been looking at this motherboard and cpus.

I have been looking around trying to figure out if the Lisbon core cpu's are any good for folding in a dual C32 setup. I seen this thread http://hardforum.com/showthread.php?t=1707547, but I am still not sure if I should spend the money and build this system or not. I figured if I build this system I will do a 280 rad in front and a 120 rad in back. I could then also retire my socket A system and move my hard drives into this system and it can also be my media and back up server.

Truely is it worth the money vs PPD or just get rid of this case and power supply and save up for a 4P G34 and have a custom UFO case made to hold the board. I have a Enermax 1000w Revolution sitting doing nothing so I have a power supply I could use for a 4P build.
 
What is your budget?

Looking at the prices you are considering, you could afford a 2p G34 setup, though I'd wonder if the EATX boards would fit in the case. Though, once you consider the price of a 2P board vs 4P, you might as well do the 4P and leave 2 sockets open until your budget allows you to fill them...
 
Personally I would go with a Asus KGPE-D16. There is a good chance tear might develop an OC BIOS for it. [H] Link

The KGPE-D16 is a lbit more( Newegg Link ) but a set of 6128 Opterons you can make up most of that price and get better performace ( 8c vs 6c ).

Just my $0.02 :)

This could complicate things.

The KGPE is an EATX board though....

I don't know of any ATX 2P motherboards...

The C32 board that the OP linked is ATX based upon the spec page.

I've got a 2P PIII and a 2P Athlon MP ATX boards in my collection as well :D
 
Yeah, actually, it appears that there are quite a number of them. That's pretty cool... learn something new everyday.
 
Could look at the intel alternative, depending on CPU budget they can be good for 120k PPD
 
I think I have two old C32 CPUs that I never even opened from the shipping package.
 
So, what is the general consensus on a dual C32 rig for SMP folding?
Forget about bigadv (and the new ridiculous requirements), what if all is being done is SMP and the budget is $1,200-1,300?

For $1,300, I can build this,

ASUS KMCA-D8
Opteron 4820 (2)
Cooler Master Hyper 212+ (2)
GSkill 4x4GB 1333MHz Memory (non-ECC of course)
WD 250GB 7,200RPM Hard Drive
Corsair 400R Case
Corsair 600W PSU
MSI GTX 550ti (cheap but capable card for GPU folding, about 9-10k PPD)

I'd say that's a pretty nice folding rig for $1,300.

for that you could almost build a 4P rig :eek:

Here are the details:
Motherboard: Supermicro H8QGi+-F $663.13
Processors: 4x Opteron 6128s $100/ea (ebay, from seller microtechcomp, just made an offer and he accepted it.)
Memory: G.Skill ripjaws 8gb, 4x2gb, DDR3 1333, CAS7 $239.96
Heatsinks: 4x CoolerMaster Hyper 212+ total $95 from Amazon (the price is up to $25.39 now, but they were $23.75 when I bought them.)
Power supply: AX750 $75 (bought here on the forums)

Total $1473.09

I still like G34 over C32 unless you have a line on dirt-cheap C32 hexes, even if you are only looking at a 2p. The question of whether or not you can shoe-horn an E-ATX into a normal mid-tower case is obviously an issue (I was actually going to try to do this with my Antec 300, but never got around to it.) Even the $100 6128s are going to be faster than any C32 chip.

Yes! I got the C32 CPUs in AMD mania back in the day. Ended up never buying the $150 open box special to put them to use.

Sometimes EATX size boards do work in chassis that they were not meant to. I fit my P9X79 WS into a Corsair Carbide 500R. Big impact was the SATA ports which you can see in that link.

And 6128 Opterons can be found for $100 to $120 a piece here on the forums and usually about $140 on Ebay. +1 for your suggestion 402blownstroker!
 
The 6128 have double the L3 cache as the 4184 and makes a big difference in folding. Though cores are import, they are not the only factor. The C32 board only supports dual-channel memory and the G34 supports quad-channel. That is another HUGE factor.
 
For same money (2 C32's vs 1 G34) 4184's will have same amount cache and memory channels plus 40% more speed (2.8 vs 2.0). G34 basically is 2 C32's under same roof.
Dual G34's can't fit ATX case ( as requested by OP), dual C32's can.
