Does anyone on TA own a SR-2 cruncher?

[ZipSpeed]

I visit the distributed computing forums on eVGA, [Hard], Hardware Canucks and NCIX from time to time and it makes me quite jealous that many of their team members have SR-2 folding hardware and I don't! :biggrin: Some guy one team eVGA has three SR-2s! I don't recall anyone on TA owning any SR-2 rigs.

Personally, I'd love to lay my paws on such a setup but it's extremely cost prohibitive. Anyone else ever consider a SR-2 system?

 

[brownstone]

I considered it long enough to see the cost of just the motherboard on Newegg... the next blow came when I looked at the cost of one of the processors and realized that I'd have to double that. :\ Needless to say, I'll be folding on the current "cheaper" setup for awhile to come.

I fold for a different team, but and SR-2 system would be awesome (2 hexacore Xeons, some nice overclocking and running -bigadv). But, alas, this is but a win the lottery wet dream [in which case I'd build lots of them ].

Imagine an SR-2 system on sr2sieve!

I wish I had an SR-2, but the SuperMicro X8DTH-6F is a good cruncher replacement. I have the X8DTH-6F with dual E5520's and 24GB of ECC DDR3. The SR-2 has a single 5520 chipset with NF200 for the 7x x16/x8 slots. The X8DTH has 7 x8 slots with x16 physical because it has dual 5520 chipsets. Also, it's EATX form factor vs the EVGA larger form factor so the board fits in more standard cases. Sure, it's not a gaming rig, but it does damn well as a cruncher and you can fit 4 dual-slot cards on it too!

Oooooooooooooo... As a Yeti, I can't complain! :biggrin: Single or dual-CPU?

Well, the little brown truck will be here thursday, and my ppd at 10pm should be over 200k ! and SR2 doesn't worry me !

Single for a week or two. I'm working on my OC right now.

I'm hoping for a baby SR-2 one day. An E-ATX board that will fit into cases withouts mods and hopefully retain most of what makes the SR-2 so great to begin with. I take it your SuperMicro board is not overclockable?

I fold for my Mom's team (at night only), but I run an SR-2 with 5620s (32nm Quads) @ 3.4 and 2x GTX580s. The HPTX form-factor is a major fail for me.

No, it's not. It's meant to be a rock-solid server board, which it is.
The X8DTH-6F has an onboard LSI SAS2008 controller but you can get it cheaper without. But the nice thing is the IPMI interface. If it hangs or goes down, I can just log into the IPMI interface and power cycle it remotely. Then, if I need to do GUI work, I can use the remote KVM-over-IP java applet to run a 1280x1024 session.

Still just 1 CPU but so far I'm liking this. Currently @4.1GHz & got TPF less than 2 min on 6051, just over 4.5 min for 6701, and currently just over 21 min for 6900.

 

[Markfw]

I gave up on the whole idea. For $600 (mobo) and $400 each for cpu's I can do way better PPD wise with 2 950's and 2 x58-ud3r's (which I now have) and for way less money ($400 less total)

Not to mention the case cost. Memory would be the same, PSU's maybe $100 more, but considering the case ($400 vs 2 x $100) I am still ahead $500

Good to know. I'm currently getting about 31:30 TPF on a 4 GHz 950 with a 6900 WU so I should be able to shave a good 10 minutes on a 4 GHz 970.

CPU folding..pshhh. I let my quad cores idle till they fix the GPU - CPU folding problems.

 

[GLeeM]

and currently just over 21 min for 6900.

OOOoooh!
That's 93K per WU
64k per day

1.46 days per WU

Not even close according to the numbers I've seen. Assuming I can get both CPUs at 4GHz+, I should be looking at 150k ppd on the good bigadv WU.

 

[theAnimal]

Less than 31 min TPF for 2684.

My 2nd CPU was delayed a few weeks but should be here next week. I've got the 1st one folding now @ 4.3 GHz on 1.3V with temps hitting 70C on air. We'll see what I can do once I get the 2nd one going.

Edit: TPF on 6900 now about 20:25.

 

[CupCak3]

Very nice :thumbsup;

 

[biodoc]

I was cruising the folding forum and found this for you all with multi-processor rigs: Turn OFF NUMA and turn ON UMA in the bios. BIG gains in tpf.

Thanks for the heads-up! Going to try this.

15:14 TPF on 6900 @ stock.

Nice! What's your clockspeeds on your CPUs?
