4 GB DDR2 RAM question 800 or 1066 MHz?

Currently I have 2 GB DDR2-800 (1x2), 8800GT 512 MB, E8400 and a P35 mobo. I was thinking about going 4 GB (with Vista 64bit). The current 1x2 GB modules will be transfered to another computer, so I am not losing anything.

The question however is this: I am getting 2x2 GB modules, shall I go for 1066? The thing is that currently, my modules are Kingston ValueRAM 800 MHz 5-5-5-18 modules, and they are working great, really great and they are 1.8v. The 1066 MHz modules that I am are planing to buy are (please be advised that I live in Egypt and we don't have a newegg here!!!) Kingston HyperX 1066 MHz 7-7-7-21 modules. I have checked those on newegg and found that many users complain that they are not true 1066 MHz modules and that they require plenty of tweaking to work at 1066 MHz with acceptable timings.

So, will I be gaining anything from going 1066 MHz when I can easily (and cheaply) get 2x2 800 MHz modules? I want real framerate difference in games, not 3DMark numbers. My motherboard is a Gigabyte P35-DS3R which supports RAM up to 1200 MHz.

Thanks a lot.

1066 wont really give you more fps, maybe loading times will be slightly faster. And, correct me if im wrong. but if you OC your CPU a bit you RAM becomes OC'd to higher frequencies too.Dr_Brocoli

So, should I just go for 800 MHz?

If higher frequencies don't provide actual increase in framerates, then what's their point?

OK. Silly me!

I did a search in past messages in this forum and found out what I needed to know.

Thanks to everyone.

It's safer to unlink them.RFOMownage

If you are going to overclock a fair bit - get the 1066. If you aren't just get the 800.JosamaBinEating

For 3.8 you would need the RAM at 845MHz for a 1:1 ratio. Now decent RAM should be able to OC that far, but there is always the chance it would not be able to. IMHO, if you can find the 1066 for just a little more than 800 than it could be worth it. But I would not spend a lot extra for it.opamando
