Ram voltage

ok what is the point of this?? i understand there sometimes can be Vdroop and so on so forth but does that means this applys to the ram too? i mean if i set the ration of FSB:Ram to 1:1 and ram is DDR2 800MHz and FSB = 400 then it should be fine shouldn't it? why would you want to tweak Ram voltages?

To basically get them working on their recommended settings and for stability I think when doing CPU stress tests.

Normally you only need to alter ram voltages when you want to overclock your ram or run tighter timings than stock. Sometimes the Motherboard doesn't select the right votage and you need to adjust it yourself.

the northbidge also helps with overclocking the RAM too

soooo increasing voltage will stablize it and get it running at its proper speed and decreasing the voltage is oppsite?? so how do i know how much should it be and when should i increase/decrease?

and same question for northbridge what does it do when i increase/decrease and how much should i increase/decrease?

and same for south bridge, and same of any other bridge i can do that too and to anything that can improve overclockability XD

I run 4GB of Ram that is rated at 1.9-2.2v at only 1.8v / 4-4-4-12 and its perfectly stable after a whole night of memtest and every stress test I have done.

The official DDR2 spec is 1.8v, but due to performance memory that runs quicker and has tighter timings, they may need a bit more. Most performance memory runs 2.0-2.1v.
