Do tighter timings call for more Vdimm?

post #1 of 2
Thread Starter 
Should I raise Vdimm when I tighten timings? Or is Vdimm only for frequency?

Yes. Say, if you had DDR2 800 5-5-5-15 @ 1.90v, you could try running them at 4-4-4-12 @ 2.20v or 2.30v.

But also remember at what ratio you'll be running the RAM, it doesn't necessarily mean you'll always have to run the highest RAM frequency possible unless you step into 400fsb territory. Than both, CPU & RAM will require somewhat a high Vc and Vdimm.
