I need tweaks to pinch out 2 more WU's a day

The title says it all...until I take a deep breath and flash the bios on my ECS board it will remain a non O/C machine. How else in the meantime can i squeeze out 2 more WU's a day? my sig is below and of course I am using seti client. I was told that the cpu priority does not make that much of a difference...but will it help if i set to normal or high?
I can see Skyhook catching up on me and if I can match his wu's per day than maybe I can egg him into a race

Well... if you have an option in the BIOS to jack up the RAM speed to +33MHz, you could try that... otherwise, if the CAS timings are not at 2... you could put them at 2, but I don't think that either of these would help to put out two more WU's a day from one machine.

I flashed the BIOS on my ECS board without any problems. It's quite easy, just be sure to read the instructions well.
