My g.skill 2GB DDRII800 kit is rated as 5-5-5-15. I can run it at 4-4-4-12 no problems but, out of curiousity, was wondering is it OK to change the CAS latency independently of the other timings? I know it will work - but is there any "formula" that says "if the CAS timing is X the other timings should be Y" etc etc. I just don't want to waste my tweaking time too much 
Thx.
