Pointers for running SMP and GPU silmultaneously

Today I started running the GPU and SMP clients simultaneously on my machine to up my PPD. I'm relatively new to serious folding, previously only having used it to test machines using the default (wimpy) client. I started folding every day about 7-8 weeks ago after seeing the latest HardOCP boxen giveaway during one of my daily visits to HardOCP.

My folding machine's stats:

Intel Core 2 Quad 2833mhz
4GB RAM
Radeon 5750
Windows 7 Pro

I'm running the 6.32GPU3 client and the 6.32 SMP client, both with unique machine ID's. Is there anything I might want/need to adjust to make this rig run as good as possible? Is running these two clients too much for this machine?

Pointers and advice appreciated. Thanks!

From my experience, I would skip folding with ATI cards, it isn't worth it. Just fold the SMP client.
 
I had been folding on the 5750 for week or two after using the standard client, and the GPU client yielded much higher PPD than the regular client. A couple of days ago I started running just the SMP client, and I didn't feel that the SMP client PPD was as high, so I switched back. This morning I got the bright idea that I'd run both.

Thanks for the input.
 
Have you folded 10 SMP units successfully within the bonus deadline yet?

I agree that you should stick with just the SMP client for now. Are you able to overclock that C2Q any higher?

The problem is that the ATI GPU client just plain sucks, and you won't be producing very much. I don't remember, but I think an overclocked 5850 was doing less than 4000ppd a while back.

if you want to run both.. i highly suggest you take a look at this thread.. should help you and improve performance on the smp and gpu client..

(ill find the [H] version of this but its the same information and im to lazy to search for it right now)
 
So folding the SMP client only is better than eating cycles with the GPU client and taking whatever points it gives? Hmm. May have to rethink my strategy here.
 
What are you using to monitor your ppd? Most folks around here are fond of HFM.NET. Don't have a link handy, but a forum search should find it easily.
 
SirMonkey, read that thread after it was posted elsewhere. Unless I missed something, that thread seemed to address stability problems, which I haven't had the week or so I ran the client.

I will bow to the experienced hands here. If the consensus is that I should just run the SMP client by itself, then that's what I'm going to do. I think I'm going to let the two clients run overnight and see what happens at the updates.

I've just been going to my personal HardFolding stats page.
 
Check out hfm. That is really the best way to figure out the best configuration for your equipment. It only takes a minute to install.

Just for comparison, a stock Q9650 can get anywhere between 5500-8000 ppd, depending on WU.

With the Ati client it is indeed, unfortunately. Not the case with nVidia for two main reasons. First, the nVidia client requires far lower CPU cycles and second, nVidia cards are monster producers that attain PPD anywhere from the high 3000s to a stupefying 15k+ capability with some Fermis. Simply no contest.

its stability and CPU usage.. the current ATI client uses way to much cpu cycles to run the work units.. why PG refuses to release an updated client/ATI DLL's for ATI cards with this fix implemented i have no clue..

found the [H] version of the fix.. forgot to mention this fix only works on vista/7 not XP..

definately download hfm.net

It makes it a look more fun and easier to optimize your configuration.

Also make sure you got your passkey here.
 
How can I pin the SMB client down to a set number of processors?

I have a Q6600 and when running 4 processes the memory bandwidth is almost completely swamped, when running 3 my PPD is much higher.
So I run 3 copies of the single CPU client.

Core2 architecture has issues with the SMP client because of poor memory subsystem performance which hampers it. You can still run the SMP client with 3 threads by using the -smp 3 flag. You should see superior production in comparison to 3 regular clients. To pin down 3 threads to specific cores, use an affinity manager tool to permanently set which CPU cores to have it run.
