Which Bios options for my Ram?

Hello together, a few days ago I overclocked my cpu with your help(E6300--> 2.5GHz), since I am a overclocking newbie I dind't change any clock times of my ram and left the Bios settings there on Auto.

"Kingston ValueRAM, 2x2GB Kit, DDR2-800, CL5" (Mainboard Asus p5b)

I've reckognized that in Cpu-Z it's written as 4-4-4-12 but I think that the initial clock speed would be 5-5-5-15.

The system system is stable and the ram are working as ddr2-720 (because of the 1:1 ratio)

My questions: should I change the numbers to 5-5-5-15 or leave them as they are set automaticaly by the Bios?

Which number should I enter as D-ram TRFC?

I don't really know if ram with a speed of 4-4-4-12 are better then ones with 5-5-5-15, could someone explaine the difference to me?

anything else I should change?

Thank you for your answers

Lol memtest 86 for 24 hours? Jesus christ. try maybe 3. Your ram is fine, you don't need to change anything.
