Processor Upgrade.....BIG ADV?

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,

 

:edit:

E5450's

 

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.

 

For bigadv he'll need the 2600K won't he?

 

Not if you follow Tarka Dahl's method of using a VM

 

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.

 

GT440 netting 12k PPD, no freaking way!

my 460 is getting 12k PPD!

 

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!!

 

It might be those 925s making an appearance. Your 460 will jump upto 15500ish with them.

 

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.

Those are Dempsey Xeons... don't bother - Basically a Presler core (Pentium 4 end of life).

 

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?

 

except those chips were slow [clock-for-clock] and generated about as much heat as the sun

 

Bah to it then,

I shall just save for a newer system

 

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.
