My i5 has a default of 20x for a multiplier. If I were to lower it to 16x, to get an overclock for my ram and my cpu, is there any negative effects with overall system performance?

Thanks.

How would lowering it improve anything?

You going to raise the fsb also? 200 * 20 seems doable.

In order for my to get my ram at 2000mhz, and get a minor cpu overclock, i'd have to lower it down to say 16x from the 20x its at now.

I'd say faster CPU than overclocking the ram.

Unless you want stock CPU and go minimum 16*163.


edit :

2000mhz on the ram would mean a fsb of 250? No?

with 10x ram multiplier, ram would be 1630. Thinking 16x cpu, 200 base clock, 10x ram multiplier.
