Folding@Home News 15th October - 22nd October 2010

Its my main machine at home, so everyone uses it, shouldn't really use it for bigadv but I cannae help it.

Problem is you get a few too many bigadv deaths on one host and you stop getting them on all of your machines :(

Might drop the O/C down a bit on this one see if it helps.
 
Yes, such blanket decisions by the work server cost me some valuable production in the past. I wish there was a more controlled way of ordering your personal work queue, so as to schedule the heavy bigadv loads overnight, say. It would certainly help your multi user case, Biffa. But f@h seems to be evolving very slowly on the usability front, and I doubt things like that will become default for a while.

I'm sticking to the normal smp units until I am certain the second cruncher can tackle bigadv without babysitting on my part. It has been a very unstable customer in the past! But to bigadv fold is its ultimate destiny, or I be damned!
 
Well the difference between bigadv + GPU3 and advmethods + GPU3 can be a few thousand points only if you get the right WU's but thats the fun of it I guess, a good bigadv + GPU3 can net that machine (Mars) near 35K PPD, but a slow bigadv can drop that down by 10K. Same with regular SMP A3 Wu's, a good SMP gives me similar output to the poor bigadv PPD, but a bad SMP can knock PPD down to as low as 22K. (Remember this is 13K on the GPU and the rest on the CPU)

All related to my specific setup, thats a i7 920@4Ghz and a GTX460. Split 7 cores for CPU and one for GPU. YMMV of course :D

Cheers for the heads-up, Biffa. I will be clocking my Xeon instead - lower power draw - to hit a similar mental target I have .

920 is a great chip, but at 130W tdp at stock, it is not exactly 24/7 friendly. I run mine at 3.5ish or 3.6 on occassion whilst topping the power draw from it at around 147W at peak, but that is at low volts. I can see it going horribly overboard with extra juice needed for 4GHz or 3.8, which is spiffy for bigadv.
 
Just a feeble x3440. I was looking at an i5-760 originally, but picked up an x3440 for twenty quid less with delivery. Quite like the little bugger now. It has a naff multiplier, but I found settings to work around it. Just waiting for some better cooling to slap on top of it.
 
Nice, 95W :D

I've got two of the same wattage (different arch) arriving in a few days, so will have two i7 920's to get rid of :)
 
What? And help my nemesis!!

No no sir, you shall have only feeble X2 Athlons and Intel Atoms :D

Yep, that TDP rating was a deal breaker for me. :D (not to mention HT!) Xeons are exceptionally good value if you can get them for the same or lesser sums than their desktop counter-parts.
 
Although it doesn't always work out, I had a Core2Quad Xeon when everyone was gettin Q6600s and it was pants, ran hot as the sun, ended up RMA'ing it for a Q6600 as soon as :)
 
Biffa, I just bought a SR-2 paired with two E5645 (6C/12T @ 2.4GHz). It's different to X5650s but I hope to overclock to 3.4-3.5GHz out of it. Can you help (as I don't have much experience with Intel bios), and provide me all your the voltage/frequency settings? Cheers.
 
Holy thread necro Batman! :D

Well they are basically i7's so its just multi/turbo and fsb overclocking with a bit of voltage thrown in for fun :) And like all overclocking each chip is different so you will get different results even using the same chip type.

You could use my settings but your best of starting where I did with the [H] SR-2 optimisation thread.

My settings are pretty much based on the ones in that thread.

Will you be running Linux on this puppy?
 
Thanks for the quick response and helpful links.

No, I'll run it on Win 7 Enterprise64. I'm not good working on linux. :p
 
I have problems with noctua NH-U12DX coolers on the SR-2. The screw hole & thread size seems to be different between the fastening bracket (noctua) and the backplate (evga).
 
No idea mate, I removed the Xeon mounting plates and put the i7 stock plates on and used normal i7 water blocks.
