just a thought

just a thought:
what is the highest clocked cpu in your Intel folding rigs?
what is the highest clocked cpu in your AMD folding rigs?
how many ppd does it make with what clients?
what kind of cooling are you using, what temps?

this is overclockers after all.

I was only able to 3.6GHz on my Q9300, although it was not folding stable at that speed. I get about 6.4k PPD running it at 3.5GHz.

I'm sure that there are some people getting over 10k PPD with an i7.

I'm about the same as edward2. My Q6600 @ 3.6 pulls 6k from two of NotFred's VMs.

I have my E8400 @ 4.3ghz folding. But it only pulls 1760 PPD using the SMP client

Q9550 running at 4.0GHz. Right now, I have two VM instances, one with 2669 and the other with 2675, both getting around 3600 PPD.

My Pentium D pulled over 2k on a single VM at 4.5Ghz, you really should jump on the VM bandwagon. You'd pick up another 1k ppd at the minimum.

Ok, well I just started my ATI on the GPU client. Ill see how this goes and if no problems, maybe ill start VM tomorrow.

i was going for just cpu, im trying to see how much cpu clock and client configuration affects ppd.

My rigs:

Duel E8400 @ 3.6, XP & SMP (Not VM) getting 1900 ppd
Quad Q6600 @ 2.8, Vista & SMP (Not VM) getting 2600 ppd
Quad Q6600 @ 2.4, Vista & SMP (Not VM) getting 2100 ppd
Quad Q9550 @ 3.5, Ubuntu & SMP (Not VM) getting 6582 ppd :santa:

GPU's
GTS 280 stock XP 5000 ppd
GTS 250 stock Vista 4088 ppd

Hope it helps :beer:

SMP performance scales pretty much linearly with cpu speed within a processor family. The Yorkfields are about 5% faster than Kentsfields at the same clock rate. The Nehalems are about 50% faster than the Kentsfields at the same clock.

doz · May 3, 2009

Well that kind of sucks. My PPD on my CPU went from 1760 to 500 after I started my GPU client.

Adjust your prioities with your clients and you will get that right back.
Or if you are using old drivers switch to new ones. The latest approved drivers use very little cpu.

Max production running ATi cards on dual cores with SMP requires the use of 9.3 or higher Cats and the enviromment variables FLUSH_INTERVAL, BROOK_YIELD, CAL_NO_FLUSH, CAL_PRE_FLUSH. The values of the variables can be set to minimize cpu utilization. For the 4870 the flush interval should be 192, yield 2, no flush 1 and pre flush 1. Playing with these variables may be required to balance SMP and GPU production.
THere is a 19 page thread on OCF about ATi core 1.24 and these variables.

well thats great info for you intel folders but what about us weird AMD folders?

tgxiii · May 3, 2009

I fold on my AMD rigs as well. OP just asked for the highest clocked processor, and since all of my AMD chips are pre-Phenom II, they don't overclock very high.

In any case, my highest clocked AMD chip is a 4850e running at 3 GHz, and it's getting around 1800 PPD on a 2669.

dark bishop · May 3, 2009

guess i should edit my original post to be a little more specific. ill have my results up when my 4gigs get here amd i can set up some vm's.

Bon3thugz43v3r · May 3, 2009

2,800 ppd - e8400 @ 4.0ghz on notfreds vm client and im also ati folding (2,500 to 4,000 ppd) :beer:

satansangel114 · May 3, 2009

I get ~5000 ppd out of my 9950BE @ 3ghz

doz · May 3, 2009

Cool, thanks for those settings CHASR. Fixed the CPU usage problem

2500 PPD on my cpu right now (no VM) and 1500-2000 PPD for my GPU!
