2p Recommendations (4p not possible)

Trying to get into the folding scene seeing as how I constantly read these boards and ever since college have had a dedicated server for files, web, etc..

I've done a lot of reading on topics already and settled that a 4p system is just more than what I want. I like the availability of the cases for 2p systems along with the abundant pci-x slots for the 2p systems as well. Please keep in mind that along with folding the system will also still be running the above mentioned services.

After much deliberation I'm stuck as to whether the 2p g34 magny cours, 2p g34 interlagos, or 2p sr2 will offer best ppd / buck while still meeting the above parameters. The sr2 would be configured with hex cores.

I found this thread to be somewhat relevant but wanted to get into more detail / opinions.

Well, budget and how thrifty of a shopper you are largely govern how quickly and cheaply you can get into folding.

Can you elaborate on a working budget a little?
 
I'd like to keep it realistically around the $1500 mark and piecing it together over time as deals present themselves is definitely doable.
 
Hmm, well, I did my SR2 for roughly that budget.

$400 per CPU
$300 for SR2 mobo
$250 for memory
$100 for PSU
$60 for the CPU Coolers
$20 for the GPU
spare HDD laying around.

You could do something similar with a 2P G34 setup, but finding the right processors would be the killer.
 
Well, greatly depends on which Intel chips you get, how good your SR2 is at overclocking.

Alternatively, greatly depends on which G34 Magny-Cours or Interlagos chips you get your hands on, ES chips are very difficult, but the best and only real overclocking option currently on 2P G34 systems.

The chips are your basis for comparison, if you can get your mitts on some crazy awesome Intel Xseries hexacores, they go for an SR2. If you can get your paws onto some awesome G34 chips for a steal of a price, go that route.
 
I know both sr2 and g34 p2 would be able to meet the core limit for bigadv but would either or both systems be capable of making the time restriction?
 
My 1P octo core 2011 makes the time limit for bonus points, in addition, my SR2 would make the time limit for bonus points (dual hexacores at 3.6ghz)
 
You wouldn't need X series hexacores in an SR-2, L series are just fine, you might not get the same overclock but they are a lot cheaper. I think musky got his to 3.6 from 2.26, and they still work fine now even though they are at stock
 
True, I was not insinuating that only X series processors are worth while. L, E or X series would work just fine. However, having said that, Some SR2s do not overclock well, few OC very well (meaning north of 200 base clock).

I have been tempted to try another SR2 board to see if I can get better results that my previous board.
 
You do know you can run a 4P board with 1, 2, 3 or 4 CPUs to get you started. Since you mentioned piecing it together as you go, all you need is the motherboard and a single CPU to get the system up and running, then as time permits add CPUs and RAM until it's a complete 4P.

You can do a 4P now for about $1500:

- SM H8QGi+-F = $650
- (4) 6128 CPUs = $410
- (16) 2GB DDR3-1333 = $260
- (4) 212+ HS = $120
- PSU = $200
---------------------------
Total = $1640

And a 2 CPU version about be: $1240 with room to grow into.
 
True, that is an option, but I do not believe that is his path intended, so I was restricting conversation down to 2P options. Having said that, 402blownstroker is very correct about room for growth option. :)
 
The only problem with going the 4p route is the limited availability of cases and most importantly pci-x slots. I have been unable to find any 4p motherboards with more than 2 pci-x slots. I currently need to be able to support at least one dedicated graphics card for remotefx capability, 2 ceton tuners, intel pro for 802.1q capability, and SAS expansion card.
 
They do exist, I an not intimately familiar with the model number for the SM board that has more, I think four pci-e slots. Someone else can chime in about which specific model that is, but I do know that it exists.

H8QGL-6F

6x PCI-E and SAS RAID on-board

That is why we are here - to talk people into buying thing they don't want for the greater good...:D

You'll pay a couple hundred more for the 6 PCI-e slot version, but you would still be under budget with two 6128 CPUs. And, a HAF 932 doesn't look THAT bad... :)
 
Twitch twitch....
PCIE = PCI Express PCI-X = PCI eXtended
http://en.wikipedia.org/wiki/PCI-X

Sr-2 has no PCI-X ....
neither do the SM g34 boards or the tyan ones...
HAF can fit 4p and so can the Elysium ...they are not THAT much bigger than an SR2...

The higher end G34 boards tend to have a LSI2008 SAS chip onboard.
 
Well he could go with a single 6174, single set of 4x2GB kit of DDR3 1333/1600, single CM 212+, PSU and SuperMicro H8QGL-6F+ motherboard for like ~$1700.

Then as time goes on, each CPU and RAM kit will be an additional ~$560.

thats pretty amazing for the price

What do you need a PCI-X slot for? That technology was so like 10 years ago :eek:

Yeah I'm wondering if the OP meant PCI-e. Especially since I doubt it would be easy to find PCI-X cards, when you could just buy the PCI-e equivalent card and it most likely be faster and more efficient.

I am hoping he doesn't and just misspoke ...
He grouped discrete gfx and sas raid card which leads me to believe he meant pcie.
 
Found this information posted by Nathan_P with stats on the minimum to make bigadv and figured I'd put it here in case anybody else stumbles across this thread in the future:

16 Thread intel xeon based on Nehalem-EP, only if you can get clock speed up to 3.6
24 thread intel xeon based on westmere-EP - only at a clock speed of 2.66ghz or better, 16 thread westmere, see above
16 thread AMD 61xx Magy cours, only if you can get clock speed up to 3ghz
24 thread AMD 61xx Magny cours, only if you are running 6172's or faster
16 thread AMD intelagos - only if you can get clock speed upto 3ghz
24 thread AMD intelagos - 2.3 ghz or better

Looks like he summarized my posts ... did a better job lol...
I am do not have enough data on the new units to know if those numbers need to be adjusted.
I made those comments based on 8101 data.
Also... YMMV as those numbers do not include Upload time.

https://docs.google.com/spreadsheet/ccc?key=0Aspl6-RkaxtFdHdTdUdmUjhWalpXWVZ2S2xvejBDcHc
 
Think I posted that on FF a while ago, these were posted with 8101 in mind but i haven't seen enough performance data on the new WU to update anyway.

Patriot is right as these do not include upload time and the statements were also partly made based on the spreadsheet he linked to in his post
 
I'm running an ASUS KGPE with a couple of G34 6168 dodecas and I crunch 8101's meeting the deadline without issue, so I'm not sure the note about the 6172's being the lowest CPU's that will meet the deadline is very accurate.

Thanks Ax, i shall update accordingly

I think even 6164s were borderline.
 
I'm afraid that a 16 thread intelagos @3.0GHz rig couldn't meet BA16(p8101)'s preferred deadline, 3.5~3.7GHz is probably needed.

Thank you for catching that... I didn't even see it.
Not even at 3.7ghz could a dual octo IL make the 2.4 day deadline...
based on Brainbugs numbers of 2p IL 16core @ 3.7ghz = 1.22 days.

New list would be greatly appreciated. It's a nice cheat sheet to have when trying to make decisions

Just remember those decisions probably won't be good for the lifetime of the system since PG seems to be changing things more rapidly as time goes on.
