Why is DDR2 800Mhz 1.8V better than DDR2 1066Mhz 2.1V?

[szala11]

As far as i understood we have much more overclocking potential on the 800Mhz 1.8V kits than on the 1066Mhz 2.1V. Right? Also the 1.8V chips have better quailty and lifespan than the 2.1. Are just these two things that make 800Mhz 1.8V brands "superior"?

I have to write the quick version of this as I have to get to work. "best" overclocking happens when you sync your ram to the FSB, and overclock it. Nearly every Intel board out there right now can hit 400MHz FSB pretty easily. Seeing as your ram is DDR, thats 800MHz. In this case, your 1066MHz ram will be underclocked. If you choose to stop there, your 1066MHz ram MIGHT not volt down to 1.8v. (most should) The other problem is that 1066 ram tends to be more expensive then 800MHz ram.

Seeing as there is no JEDEC standard for 1066MHz ram, it is assumed that these are simply 800MHz ram thats overclocked. The quality should be the same, as should the lifespan. The 800 is superior because thats all most of us really need.

When overclocking, its best to set the fsb:ram ratio to 1:1. If you buy 1066mhz ram, then you will have to underclock it to be able to sync it 1:1 with the fsb (unless you have a mobo and cpu that can reach 533mhz fsb ). Also, you are better off buying 800mhz ram with low timings than 1066mhz ram with higher timings. Beyond 800mhz ram, the timings are more important than the bandwidth.
