If I take a stock OCZ stick of DDR2 667MHz PC2-5400 4-4-4-12@ 1.9v and overclock it to 2.2v - 2.3v does that technically automatically transform it into a stick of PC2-8000 1000mhz <-> PC2-8800 1100mhz. Because the PC2- 8000/8800 are generally rated stock @2.2v - 2.3v. If so, the sacrifice would be the low latency timings but is the gain in raw speed worth the cost? So the sacrifice of latency would be less if the initial PC2 - 5400 was instead say 3-3-3-12?

Overclocking from 1.9v to 2.3v guarantees increased speed, or lowers latency, or both, or I get to chose which I prefer?

Just increasing voltage by its self will not overclock your memory, overclocking is where you manually increase the spped of the memory (or cpu etc) either by the FSB (intel) or HTT (AMD) or you can change the ratio of the memory divider to increase memory speed. Again latency is changed manually in the BIOS too.

Try to do some more research into what overclocking is and how to go about doing it before you make any changes in you BIOS.

upping the voltage does not guarantee a really high speed. PC2-8000 and up are usally high quality ram that was specificly made to handle high voltage. your PC2-5400 may get up to 800mhz and higher but it all depends. I would say check some reviews of it and see what other people were able to get to. Also note that what other people were able to achieve, you may not be able to duplicate. its sometimes hit or miss.

PS 2.2 - 2.3v are really high voltage settings, you may kcuf up your ram cause of it. I would advise to stay away from those settings

I'm not sure I understand what you're saying here but I'll take a crack at it. Raising the voltage is not overclocking, it's over-volting, you overvolt in conjunction with overclocking to yield better results. When you overvolt it enables you to raise the frequency or tighten the timings. Raising the voltage alone will not increase performance. Also, those high speed DIMMs you mention are the best of the best, it's very unlikely that lower grade RAM you mentioned will make it anywhere near that. Read up a bit more before you go changing anything in your BIOS.

Yeah, if you can get the module up to 1000 Mhz at 2.2-2.3V, then you technically have a PC2-8000 ram....

But, usually memory vendors use different chips for their higher memory speeds. Say the PC2-8000 ram uses Micron or Samsung chips, while the PC2-5400 uses Elpida or Powerchip chips. The Micron and Samsung are usually very overclockable, and usually cost more for the vendor to buy to make their modules, hence the higher prices for the PC2-8000 rated sticks.

Now Elpida and Powerchip are much cheaper, but are not as overclockable, hence the vendor uses these on the PC2-5400....

Suppose I overclock my E6600 to 3000mhz 9x333, there would be no performance advantage for me to use DDR2 1000 over DDR2 667 ? Because for me to benefit from DDR2 1000 my cpu fsb must at least be @500?
