ok i have a ecs pa1 mvp (heres the link)


http://www.ecs.com.cn/ECSWeb/Products/ProductsDetail.aspx?MenuID=0&LanID=9&DetailID=558&DetailName=Specification

it says it <Support DDR2 667/533/400 DDR2 SDRAM!>

but the thing is i wana get a <CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory> (hers the link)

my question is would i still be able to run this even thoe its running at 800 and my mother board supports up 667 only... would it still work?

thanks

It should work, but the memory will only be running at DDR2-667.

It depends.
Find out if your BIOS can go up to 400Mhz in memory. If it can, then, once the modules has POSTed (youll need some luck and relaxed SPD settings) you can set it to the advertised specs.

He's got an ECS board, and from the post it didn't sound like he's the OC sort...

i know this is a stupid question but how do u check if it can go up to 400mhz :? ?

 

[Mondoman]

If your MB has the settings to allow it, you try it and see if it works. To "see if it works," you run memtest86+ for a number of hours to check for errors, then PRIME95 (one per CPU core) in stress test mode to check for errors. Most likely, it will not work (because then ECS would have marketed the MB as supporting DDR2-800). Bottom line: don't even try it, as you might get into trouble.

yeah im prob not gona try to oc it sence i dont know how.. so i mean i should be able to run 800mhz on a 667mhz board right?? oh and i saw this on newegg its a 675 i should be able to run that right?

Just like you can always drive a Porsche at 35 mph, you can always run faster RAM at a slower speed.

Hold it. I looked at the site for the motherboard and it says that it supports DDR2 667/533/800. Since it says it supports DDR2 800, you should be able to use that memory without a problem. You may have to specify it in the BIOS, probably not, but either way, the board supports it. Go ahead with the 800 ram and enjoy.

Well if you arent going to be OCing at all, you dont need anything more than DDR2 533 to run it at the same speed of the FSB.
Expensive RAM only prooves a very slight improovement if you arent OCing, definetly not worth the price.
