I'm on my way to buying larger and superior memory for a Vista upgrade. My Dell notebook runs with an Intel Core 2 Duo T7200 CPU.

Looking at NewEgg, I see three options. I can choose between "DDR2 800 (PC2 6400)," "DDR2 667 (PC2 5400)," or "DDR2 667 (PC2 5300)." In terms of maximum compatibility and speed with my system, and notwithstanding cost, which of these three is the most superior buy?

Maybe you could post with your laptop model number, then (speaking for myself) I could recommend some part numbers with relative certainty.

It's the Dell E1505. Let me know if you need any more info.

Anything over DDR2 667 (PC2 5400) will just be down clocked because your laptop doesn't support frequencies any higher.

hey i'm building a pc for the first time and i googled this same question and came back to this friendly site, now my questions are how do i find out what the frequency of my system is?

you said "anything over DD2 667 (PC2 5400) would just be down clocked) does this mean that you can actually put any variation of pc2 5400/6400, their performance will just be limited to the frequency of you system?

also, if a mobo has DD2 DIMM slots (since every motherboard specs i have read say DIMM followed by Dual Channel im now assuming that if it says DIMM it's dual channel, please correct me if i'm wrong) i can put in a set of dual channel DDR2, however can i put in two regular sticks of DDR2 that are non-dual channel into a set of dual channel slots?

anyhelp would be appreciated thnx in advanced

Hi there,

Next time feel free to start a new topic, this thread is quite old now. It's also talking about laptop RAM, which is marked as SO-DIMM.

A simple test you can run online is at http://www.crucial.com/ Run the scanner and it will return with results on what type of RAM you have and what upgrades are available. You don't necessarily have to purchase their RAM, although Crucial do make good RAM, but just take down the information that you need.

If you are building a PC and don't have any parts yet, then the RAM specifications you need to know will be listed under the motherboard specifications. If you can't find it, post the motherboard make and model here and we'll help you.

Cheers
