First of all hello everyone I used to be on the old CPC forums a few years back but started university 2 years ago and the world of PCs became very distant to me as all I had to tinker with was my laptop Now however I have managed to get my rig I built back in 2008 through to uni and have started folding again I know my PPD is nowhere near everyone in the top ranks' but I'd like to do everything I can to maximise the points I can squeeze out of my current hardware! Now I know people are saying "GPU folding is almost dead" but since I don't have and can't afford a more powerful CPU based setup at the moment my GPU is my biggest producer. The GPU I'm running is a BFG 8800GT OC2 Core Clock: 675MHz Memory Clock: 975MHz Shader Clock: 1674MHz Currently using the v7 client for the GPU (used to use the GPU2 client - have had no difference in tpf between the two clients) and have no flags set up on this client. I've got two main issues: 1) Most people seem to be averaging 4500-5000ppd with an 8800GT and I'm currently showing a 4200ppd with a TPF of 1m 38s. The only WUs I've been getting lately have been Project 10122 based with 494 points per unit. 2) I've been browsing the Folding forum for a while and couldn't find much about GPU overclocking and it's affect on PPD. Does one clock speed affect the GPU's folding capability more than the others? Also I've tried overclocking the GPU further (checking the OC for stability first using 3DMark06) but any further overclock only has a detrimental effect on the TPF moving it to 1m 44s. My main concern is that my PPD seems to be decidedly lower than other 8800GT users and was wondering if anyone had any idea how I can resolve this? (without buying new hardware before anyone tries to be smart ) If anyone wants/needs more information just let me know Thanks in advance!
