Morning All, At the moment I have a Dell Precision 490 with 2 x Xeon 5160's in and a GTX 470 GPU. This rig doesn't fold at the moment as i am waiting to upgrade the heat-sink on the GPU as she runs too Hot for 24/7 folding. Me being me, and apparently suffering from Lizards upgrade addiction, was thinking about changing the CPUs to 2 x Xeon E5459's http://ark.intel.com/Product.aspx?id=33083&processor=E5450&spec-codes=SLANQ,SLBBM Ebay being the probable source for these would mean spending around £ 300.00 for two of them (if i get lucky). My question is, what sort of PPD would you expect, and would 8 physical cores at 3ghz be enough to handle BIG ADV? Cheers all,
firstly: you can edit your posts you know... secondly... i think you may be pushing it running bigadv, though others on here will have more experience with bigadv
Although I have no experience with bigadv, just by looking at the specs I think it's safe to say it will be faster than any i7 at stock speed. Will it be faster than a 2600k @5GHz? Probably not. If you only had a few overclocking 'knobs to turn' on that Precision...
You'll definitely be able to run the bigadv client and get some bonus points on those chips (I used to have a similar rig... it's now retired), but given the price (even on ebay) I reckon an i5-2500K on a cheap P67 motherboard would get you more points at a much lower electricity cost.
Would i need VM ware though? Remember there would be two CPU's both of which have 4 cores. Anyway who needs BIG ADV when a little GT440 gets some good work units........LOL 12kPPD The proof is on an album I made, but couldn't figure out how to insert the image into the string.
LOL its now down to 6k now. I am assuming a couple of easy units were thrown at me. If someone can tell me how to insert images into the strings then i can prove it!!
Found some other chips now. Proper cheap @ £ 40.00 each, and they are 5060's @ 3.2 ghz but with HT. That would mean 8 threads. Im sure this would complete big adv but just want to check. This would enable me to upgrade my second rig which isnt folding yet to a big adv system with minimal costs. Thoughts please?
Running and i7-920@3.8 it comfortably does bigadv units if running 24/7. So yours should do it as long as it engages boths CPUs for the one project, based on the clock speeds of 3.2GHz. A bigadv usually takes around 33min a fold, so around 55 hours to complete on mine. Usually I get 72-84 hours to do it. Adding advmethod changes that. I just did one and it was 45min/fold 75 hours total and it was around 90 hours deadline.
They probably are, but to take a none folding rig at the moment and create a big adv capable one for £ 80.00..............cant be a bad thing, now can it?
It would essentially be a 4 core netburst machine. Capable of SMP, but it would be hammered by -bigadv units. I think you would be lucky to get them done within the preferred deadline, so don't count on any bonus points.
You could try Thishttp://sites.amd.com/us/promo/processors/Pages/fx-processor.aspx when it comes out. shouldn't be TOO much.
