I have 2 GB of 800 Mhz kingston value ram.Cpu Z shows some very strange timings 6-6-6-31-24.I have an Asus P5N-D and a E8400 Oc'ed to 3.6GHZ with memory linked sync mode.This is my memory but with CL=6 not 5 I didn't find the specs for my memory they're no longer available on the kingston site.
What timigs should I use ,voltage and should I change some other settings in my bois? Cpu vcore =1.1875 ,NB=1,42,SB=1,60,HT=1,46.

I think your specs is still on kingston site, but as a PDF file. Google the model & click cache instead of the actual link. Cache is on Google.

They a a model similar to mine  with CL=5   but mine has CL=6
