Quad Opterons or 4 x 2600k?

post #1 of 27
Thread Starter 
Hey all, I'm thinking about adding another machine to my "hobby" farm.

Was looking at a quad opteron board and 4 x 8 core cpu's. The problem here is that there is no overclocking support on most server boards.

For the same money, I could get 4 2600k's on z68 and oc them to the sky.

So 32 Opteron cores at 2.0 Ghz and a ton of quad channel ram

or

16 hyperthreaded cores at 4.7-5 Ghz and faster dual channel ram


Which is better? Would be native linux obviously. Is it possible to run more than one motherboard per PSU?

I think the 2600k's would be faster.

Get the i7's. If you were crazy get i5 2500k's and get them to run Bigadv. You could add 1 extra rig possibly.

if your PSU is big enough, you can run two machines, but you are going to have to mod the main ATX outupts. (Double the wires and have a connector) I have done it at work, so I know for sure it works, atleast on older systems.

As far as the Opteron/2600k's. Not sure, but interested none the less.

I would go with the 2600K's. I have 4 of them folding @ 4.5ghz 24/7 on big bigadv's, and woah.... you're looking at 308K PPD or +1million points when they drop (all at the same time).

the 2600K's do cost less, the PPD they make are well worth the cost .vs perfomance

Depending on how much you pay, the Opteron option could be very positive
post #8 of 27
One of the advantages of the opteron board is that it will take Interlagos cpus. Those are going to be 12/16 core cpus. I imagine that by the time those come out AMD should have fixed a lot of the Bulldozer issues. Not to mention that you will only deal with 1 computer vs 4 individual machines and should have less problems with stability due to the fact that there is no overclocking involved.

If I had the money I'd def go for the Opteron option, partly because what mach1 and Desert posted. And the power draw would be lower on the Opteron (around 500W iirc) and a 2600k draws around 200W right, so 800W for four of 'em. And it's way cooler to have a 4 socket machine folding than a measly single socket.

I would like to say that the socket G34 motherboard build would be very good. If cost isn't a problem, then the G34 solution would make the most sense. * didn't see a budget *

As far as running multi. systems on 1 psu, I've seen 3 z67 motherboards on 1 psu. You need to have a special 24 pin Y cable and then wire the motherboards to all turn on at the same time. You can't have 1 just on and then turn the others on: It's all or nothing. I believe the build I saw, the guy used a Antec High Current 1200watt psu for that build.
