Calling all RAM Experts - Help me with this plz

[luksi]

Following on from my previous thread where I asked about which RAM to buy for my 3 yr old Dell dimension 8400 desktop pc which came with,,,

samsung 256mb - 1R x 8 PC2-4200-U-444-10-A1 (2 sticks)

anyway i ended up purchasing this

http://www.scan.co.uk/Products/Produ...oductID=402849

with the understanding that even if it didn't run on 800 mhz , if i ever upgrade (likely) then i will benefit from the 800mhz then..

got the goods today from scan (well done for quick del guys @ scan) - but to my disappointment its only running on 533mhz !! ?? I have taken the old RAM out completely and currently just using the corsair sticks

my question is.. Can i possibly do something to increase the speed even to even 667mhz which what I was atleast expecting ??

as u can see on the following link crucial does say my MB can take
Each memory slot can hold DDR2 PC2-4200,DDR2 PC2-6400,DDR2 PC2-5300 with a maximum of 1GB per slot.*

so this info my crucial a load of cobblers ?


TIA

ok after reading the corsaier forums from other dell8400 users I FIGURED THAT my pc can max support pc4200 only (533mhz)

is it worth future proofing with RAM ? or pretty pointless, i dont think i will upgrade my comp for another yr atleast

also which slots do i need to put the ram in 1 and 3 or 1 and 2 ?

i am using the 2 corsair sticks only (1gb each)

thanks

PC6400 RAM will still be useful in a year's time. PC4200 probably won't. Install the RAM in slots 1&2.

cheers m8

i have it in 1 and 2

says dual interleaved, shouldn't it say dual mode ?

That's the same thing, interleaving is what you want (though it only really makes any difference when using integrated graphics).
