[Solved] I need help on my RAM Timing

I bought a Kingston Value Ram (1Gig) with this product ID KVR800D2N5
which I believe has the Timing og 5-5-5-18-23 (shown below)

I already have a 2Gig Kingston Value Ram (KVR800D2N6) memory installed on my system, which I also believe has the timing of 6-6-6-18-24

What correct timing setting should I apply? Should I used the 5-5-5 timing or the 6-6-6? Or, are this two modules compatible?

I am currently using this timing 4-4-4-12-16

Thanks OverClkr.... just a few more questions..

Does the 4-4-4-12-16 setting would cause my system to run under-performance? And does the timing setting affect the FSB of my system?

Thnks in advance

If you are mixing memory speeds, you may need to go with the slower. What I would do is relax your timings to 6-6-6-18, increase RAM voltage by a tenth, then install the new memory. Then test and work your settings downward until your system becomes unstable.
