My high end dedicated folding rig is getting a very low PPD

post #1 of 10
Thread Starter 
First off I'll start by sharing the specs of it.

i5-2500
EVGA GTX570 HD (2.5gb)
Asus GTX285 (1gb)
2GB of ram

I recently learned from a user on another website that has an i5-2500k and a gtx570 that he is getting more points than I am total. I noticed that the 570 seemed to be less effective than it should. Are there any ways I can improve the performance of my rig? Its producing too little for me to justify the heat and energy its using.
I was told to try GPU tracker Which got both cards running at the same time but I still seem to be producing way less than I should. I remember using the 570 once for folding before and hitting 30kppd on it.

Any help would be appreciated.

I am currently not folding for OCN, but if Im able to get the rig folding as it should I'll gladly switch to OCN's team.


This is what another User is getting with a similar less powerful configuration: http://i.imgur.com/N0EyCM8.png

Here is a picture of my machine's configuration.

You may find that the GTX 285 is causing the low PPD on your 570.

Hello,

That does look a little low for the 570 on a 762x WU. Your 2500 could do better also.

I've got a 3570@4.5 that folds in a Linux VM and a GTX 660 Ti. Combined, and on what I consider good WU's right now, they do about 63K PPD. However they aren't always getting the 25K PPD SMP WU's and 38K PPD GPU WU's... sometimes the CPU has a WU that's more like 18K PPD and the GPU one that's more like 26K PPD. For that matter I hear of i5's and i7's doing 40-60K PPD on some WU's, although I've yet to see one of those. So actual PPD is going to vary.

What you can do about it-

Very basic- Do you have a passkey? If you don't get one and put it in with your identity in GPU tracker so that you receive a Quick Return Bonus for SMP work.

Hardware config- Why did you disable 1 CPU from folding? I think your 2500 could do at least 12-15K PPD. If you have the ability to overclock it, it can do even better, even if the only option is just a small BCLK adjustment. Overclocking the graphics cards (if they aren't already) might also give a small PPD gain. The faster your CPU can finish its WU's the more bonus points adjustment you'll get. Sometimes CPU and GPU can fight over CPU resources, make sure their priorities are GPU > CPU. With one CPU core not folding, this shouldn't be a problem. So if you turn that core back on to folding, keep an eye on your GPU loads and make sure they're staying pegged at 99-100%. Its an easy configuration fix if they aren't.

OS config- Use Linux. Folding in Linux usually sees a small PPD gain (~10%), even if you just run it as a virtual machine on a Windows host. If using the free vmware player, adding the option:
priority.ungrabbed = "idle"
to the VMX file will make sure the CPU's yield the tiny bit the GPU's need to fold at full speed, and that the VM otherwise operates very unselfishly when it comes to resources while the VM is minimized.


FYI, I'm just a visitor from team 32. Good luck with your folding endeavors.

What is your GPU utilization? My 570 gets 3x what that screenshot shows.

If you upgrade to v7 you can get a4 units. And you could probably run SMP4. And as mentioned, a passkey and Linux SMP folding help a lot.

I have 1 core disabled because I was told it would allow the gpus to do better. I also have a passkey. Ill try some of the tips.

Also how would removing the GTX 285 help? Im curious.

Well you can try SMP3 and SMP4 to see which one gives you more SMP PPD. It kinda depends on how much CPU utilization is being taken from the SMP WU.

You definitely have something screwing up your GTX570 PPD and it is not your CPU utilization either.
I have run mixed setups with fermi and older GPUs recently and the fermi GPU took a dive in PPD.
What does it show you for GPU core usage using a program such as MSI afterburner to monitor it?

Currently my 560Ti is getting 25k ppd on one of the lower point units... I will throw one of my old 200 series cards in with it to test this out for you.


Edit:
I did not get my PPD to crap out by adding the second card ... but it could be something to do with the configuration...

Not sure if there is a way to specify GPU/Cuda IDs in GPU Tracker but sometimes it helps with different types of cards in 1 system.

This is how its done for V7

Run v7 and see what you get.
As mmonnin suggested, you will have to do some wizardry to get fermi and non-fermi to play nice in v7; very simple tho.

I will give v7 a shot again Thanks for all the help everyone.
