PPD for a Q6600?

hmm I get about 4400-4500 PPD using 2 instances of windows SMP clients with my Q6600 @ 3.56ghz under Vista 64

Not meaning to question that but how??:eek::eek:

I get a fraction over 3k ppd with a Q6600 @ 3.15ghz running 24/7 and 2 win smp clients. i can't imagine that another 400mhz can produce a jump of 1500ppd

What is your average frame time?
 
For comparison, I'm running 2 WinSMP clients on one of my Q6600s at stock (the useless clocking one) while I'm at home and am getting about 18-18.5 mins per frame for a PPD of 2,700-2,800.

This would mean booyaka getting an extra 300-400 PPD for 750MHz and gurusan getting an extra 1700 PPD for 1160MHz. Something's not right somewhere - either booyaka's rig isn't performing as it should or gurusan's is punching well above it's weight.
 
booyaka. I think there's either something wrong with your setup or you're using the rig for other purposes or something. Looks like gurusan's PPD is about right.

I've set up 2 WinSMP clients on my other Q6600 @ 3.0GHz and it's taking 13.5 mins per frame, giving me a total PPD of about 3750. I've just tweaked the memory timings and will see if that edges it up any (got the RAM running at 833MHz at 4-4-4-12 @2.1V - not bad for cheapo Geil stuff).

The second rig is on a fresh Windows install with very little else on it, which may make a slight difference but not that much. I decided to switch because all my quads are getting on Linux SMP just now are the P306* WUs which were giving me a total PPD of about 2500 running 2 clients - I'm now getting 1 1/2 times that running WinSMP clients (always seem to get P2653s on Win SMP). I won't be switching back until the weedy WUs are finished.
 
hmmm - well my ram is 4-4-4-12 @ 2.2v running 1:1 with FSB @350.

It is used also for some gaming etc etc but not heavily - maybe 90mins a day or so.

-- f@h number 1 --

Avg. Time / Frame : 15mn 13s - 1665.54 ppd
-- f@h number 2 --

Avg. Time / Frame : 17mn 57s - 1411.92 ppd

One is running slightly slower than the other ( running from 2 seperate drives) but nothing else major running during the nighttime or day time when i'm at work etc.

Also killed off a few un-needed processes in windows etc see if that helps.

weird.

Very.

Tightening the timings has knocked off about 10s per frame so far - giving me an extra 50 PPD or so - up to 3800 now.

Your RAM is running slower than mine but that should be cancelled out by your extra 150MHz CPU speed. Maybe your gaming is having a bigger impact than you think :confused:

Well I dunno...but this is according to FAH

Looks good to me mate. Seems to correlate with my experience. I get 1000 PPD more from a 600MHz OC with tighter timings which would seem to suggest that your 520MHz extra with the faster RAM would easily get you the extra 600PPD over mine.

Nice OC btw :)
 
running my Q6600 @ 3780, RAM @ 4-4-4-12 with 2 WIN SMP Clients, each client is pushing a unit out on average at 11 mins 51 seconds

Edit:

Well enough units done now, recons my PPD is: Client 1: 2539 Client 2: 2573

anyways late time for bed :)

Edit 2:
Last super sneaky edit before bed (Turned a load of rubbish off!):

Avg. Time / Frame : 10mn 19s

Avg. Time / Frame : 10mn 08s

thanks - will have a look at this later today.

Also does having a higher FSB, i.e 400x 8 help rather than 352x9 (both being roughly 3.2ghz)???

I always prefer higher FSB clocks because they help out benchmarks...I'd imagine they would help folding a bit as well, but by how much I couldn't tell you.
 
would imagine that where a process has a lot of communication between CPU <-> RAM that the high FSB would produce "faster speeds" if this is noticable in the "real world" I have no idea

Also I would imagine this effect would be greater on a quadcore where the CPU is "doing more" and potentially using more RAM

well optimiser installed and wahey - what a difference!!!:p:p

amazing effect on my system now!:D:D:D:D
