I'm hoping someone here can advise me on buying new RAM for my laptop (Dell Latitude D400). I'm thoroughly confused about specs & compatibility. It came with a single 512MB module (plus one open slot). Here's the specs Dell listed for the module I have:

1 K4124 DUAL IN-LINE MEMORY MODULE, 512, 266, 64X64, 8K, 200, 512

Not very informative. I ran Crucial's memory configurator and it says if I want to get another 512MB, this is what I need:

512MB, 200-pin SODIMM, DDR PC2700

The Sysoftware Sandra system analyzer identifies what I currently have as:

512MB DDR-SDRAM
Memory Bus Speed: 2x 133MHz (266 MHz data rate)
DIMM Synchronous DDR-SDRAM 512MB/64@266Mts

One option is just to get another 512MB module for the open slot, but I'm not sure what speed or PCxxxx it can/should be to be compatible with my existing module. Crucial wants $53 for their 512MB module. I'm thinking a better option might be to spend a little more and get two 1GB modules (discarding the 512MB one I currently have), but I canít tell if the 1GB modules I see advertised many places will work for me. Some list speed; some just list PC- or PC2-(whatever) Ė Iím lost. Can anyone help?

Here is an example from newegg:

http://www.newegg.com/Product/Product.aspx...N82E16820150633

much better prices than direct from crucial.
The name says it all -- 59 and holding permanently

There are benefits to ordering from Crucial.com
1) Lifetime guarantee
2) Rapid delivery - and rapid replacement if the shipment gets lost
3) Not too much more expensive than NewEgg
4) Guarantee'd compatibility
5) Comes with instructions
6) Good tech support

Thanks, guys. I'm wondering if I can maybe get the best of both worlds with this 1GB Crucial module that's currently only $50 after rebate at Buy.com:

http://www.buy.com/prod/crucial_1gb_pc2700...2/10393180.html

I suppose I should see if I can return it if it doesn't work.

If you can find out the CAS latency of your current chip, it will decently improve your performance to get the second chip at the same latency.

The Buy.com RAM appears to have the same specs as the RAM that Crucial recommends for your system - but the part number is different. In short, it'll fit but I'd expect warranty issues to be a bit confusing.
