title says it all. my cpu folding score is extremely low. like at 800 ppd right now on project 7647. im overclocked to 4.5 and its not overheating at all. i have my 6950 going as well and its getting about 9000 ppd. idk if that normal but its a lot better.

what can the problem be?

There can be a pretty big variation of PPD depending on the WU you are processing

on F@H forums I saw Grandpa_01 : i7 2700K @ 4.8Ghz smp gets between 12,000 (WU 7611) and 27,000 (WU 803x) PPD

so it sounds like you are floating around the right ballpark

in the past using Hyperthreading while folding was beneficial, but currently running SMP on all virtual cores will actually hurt your PPD - as they do not have floating point registers and the extra workload falls to your Physical cores slowing the overall processing of WU's
as you get a disproportionately large reward for Fast completion of WU's... running hyperthreaded SMP cores looses you the Fast completion even though you do more work.

People often reduce the number of virtual...

Do you have any flags set?

I'd probably cancel the WU by deleting the SMP slot in config and setting up a new one... and hope I get something more suited to the machine. That looks like some kind of bigadv WU.

what is a flag. im new to all of this stuff. ill delete and start a new one.

Im probably confusing because im confused lol.

it seems like i am in the right ball park just want some verification. is there any tricks or secrets that i could be informed on?

also i decided that from what i read i should get about 28k from cpu alone and about 20k from cpu + a gpu and if my gpu will get about 9k then id rather save the electricity and go just cpu but after finishing and deleting the gpu slot my smp8 process will only use 7 threads. is that because thats what the slot started out at and cant go higher or what?

If you're wanting to run with only full SMP, click 'finish' so it won't automatically start folding a new WU. When it's done, edit your SMP slot in config and set it to 8. You previously weren't able to run 8 due to your ATI/AMD GPU. You'll probably have to quit and restart the program for it to take effect.

Actually, it may work if you just pause it too. Pause, edit, quit, restart.

People often reduce the number of virtual cores running by 2+ to improve distribution of system resources and does not lower PPD + can improve it.

If you want to use your (ATi) GPU you must set aside a CPU core to "speak" to you Ati/AMD 6950 or you will get Very Low SMP PPD
The Spare unused virtual cores are enough to help feed the 6950 successfully I believe

Soon i need to upgrade my system, more PPD and less power usage, electricity costs too much here in the UK...
am currently stuck on those nasty 7611 SMP projects for the last 2 days, has lowered my PPD by maybe 20%

Well, have an experiment and good luck on your folding :)

best answer to you.

you basically covered what i was looking for. i am in the ball park as ive completed 2 11k jobs since 11 last night and am hovering around 25k right now.

why thank you :)

I finally got off that nasty string of 7611 SMP projects (2935 PPD)... now on a 7010 - giving my SMP PPD about 6,000
and my 5850 is pulling about 6,500 on the 11293 project.
Makes for my Best overall PPD so far of around 12,000 once it settles down ^^



Just to add one thing for others...
...NVidia GFx cards do not have the need of the extra CPU core or virtual cores to feed them data, is something only ATi cards require
