is there anything wrong with 800Mhz ram

I keep seeing forum posts DO NOT GET 800Mhz ram



is it disfunctional or what

Theres nothing wrong with DDR2-800 RAM (if thats what you mean).

Although I think I may know why they are saying that. When you have faster RAM, it requires either more voltage, looser timings, or both, so with DDR2-800 RAM vs say, DDR2-667, a lot of companies end up raising the voltage of their RAM anywhere from 2.0v-2.2v. And with a few motherboard types, they do not work well with RAM that is clocked over 1.8v-1.9v, and in some cases the computer simply doesnt boot.

A motherboard's RAM Bus will support up to 800Mhz, without overclocking, there is no reason not to get it.

Depends which motherboard and chipset your talking about.



But with such a wide variety of RAM to choose from, if your motherboard cant support RAM over 1.8-1.9v, then just look for DDR2-800 RAM which runs at 1.8v.
