Core a0

Does anyone else use the uniprocessor client?

Mine have been picking up the new gromacs33 units and they seem terribly inefficient and slow for the PPD they're producing.

Its somewhere around half what AMBER or GROMACS cores produce.

Time to laugh but heres what I have folding.

Eeepc 701SD 961mhz
T1500 1.8ghz ( 2 Clients) I'd try SMP but as its not on enough I dont think it would make deadlines
Athlon XP 3800+ 2.4ghz

I have an athlon II 240 system coming shortly that will overclocked by a reasonable amount and I'm going to see what that run SMP like.

While I'm here the Athlon II is being built on a tight budget and wondered what you would advise as best PPD/£ GPU I dont mind buying used either.

So far I'm looking at GTS250 or 9800GT Green

Didnt know there was a premium on them, as I understood as they we're underclocked they would run cooler and draw less power and I could gain a few more PPD by overclocking the shader core.

Looking at the graph on this page http://www.bit-tech.net/bits/2009/08/03/how-to-build-the-best-folding-rig/4 how does the GTS250 beat the GTX260 when its 128 vs 216 shader cores. Is this due to the 600mhz difference in shader clocks?

But then I can still find GTS250s for £5 less than the 9800GT and it performs better according to Bit-tech

Entire rig or GPU wise?

Frozennova · 9 Apr 2010 at 19:10

Its being built in stages as its acutally for the misses and she's on a low income being at sixth form, but she's letting me fold on it.

so far its

Asus TA-861
Gigabyte GA-MA78LMT-S2
OCZ StealthXstreme 400w

£110

Then I'll be adding

Athlon II 240 - £50 ( 3.2Ghz overclock maybe more once I buy a new cooler)
Patriot Sector 4Gb £86.99

GPU cost will be minimal as she only wants to play Sims 3, So I'm looking at no more than £100

I'll also be upgrading it to a quad once I've sorted my finances and moved into her parents house, and it'll be replacing the laptop with the T1500 mentioned above

She's not great at leaving money in the bank account untouched like my self so its easier to buy bits each time she gets paid. I think her parents are paying for the rest part earlier birthday present and she's getting £100 for her current laptop as well.

I've found the GTS250 green for around £80

Second hand is always an option when building a rig so I'll be keeping an eye out on MM for a 9800 of some description or a 250.

Whats the crack with folding on two GPU's do they have to be in SLi or does it not matter?

Frozennova · 9 Apr 2010 at 20:15

So I should in theory have no problems running say a GTS250 in the PCI-e 16x slot then another say 8800 or 9800 in PCI-e 1x slot due to the GTS250 being a refresh?

Frozennova · 9 Apr 2010 at 20:22

From a quick search they're both G92 cards so they should be compatible.

However a GTS250 and a 9800GTX+ will be pushing the PSU a little ( 355 watts system total @ 100% load)

Looks like I'll be making a dummy plug as its only gunna be a cheapy monitor
