will sodimm DDR2700 work in a DDR2100 laptop?

Consult your laptops manufacturor's website, they should be able to tell you!

Correct, on notebook memory DDR and DDR2 is physically seperated from going into each others slots by that .5mm difference.  Return it and get DDR2 4200 / 533 RAM.  It is better and faster than 333 RAM.

Yes I have a Sempron Sad to say and you can Mismatch any type of PC3200 DDR 400 in a sempron all you have to do is add it in a available memory bank and if one is not available you will have to take a old one out and replace with a higher capacity one.

dont use ur old stuff unless its ddr2 ... if its older than 6 months it isnt ... dont mix the types or you'll slow everything down , just add another 512 if you have a SINGLE stick, and check out the site the guy above mentioned to get the same speed memory ... if you have two sticks of mem now they are 256 each and most likely in dual channel configuration ... in that case i would get the same speed memory but buy (2) 512s' or (2)1gig sticks ... if you break up a pair of sticks in dual channel or add a third you will slow things down also ...

No, DDRam and SDRam are two different and uncompatible types of Ram.  If your new motherboard takes DDR and you only have SDR, you will have to go out and purchase DDR.  Sorry.

The technical answer... DIMM = Dual Inline Memory Module.  DDR = Double Data Rate.  Really, they are independant of each other.  To really confuse you, DDR (and DDR2 for that matter) memory comes on a DIMM.  The DIMM can have different configurations, and as mentioned already... different speeds, different timings, etc etc.  So, the answer is not a simple one.  The best thing to do, as mentioned already, is to check your motherboard manual to figure out what kind of memory will work.  If you bought a "manufactured" PC from a big company, this may not be in your manual.  You may have to go to a memory manufacture's website to figure it out.  See my link in the Sources section below.\n\nThanks,\n\nGraham.

you can put two 512mb ddr-266 dimms for a total of 1 gb pc2100 memory

The differences between these memory chips are speed, types, and compatibility.  In addition to the DDR (double data rate), there is also speed, usually follow by DDR3200 or DDR4200.  The higher the number, the higher the speed.  You should check what is the maximum the memory the laptop can take. Most laptops only allow memory upgrade up to 2 Gigs.

go to http://www.crucial.com put the name and model of your computer in the search place and it will show/tell you

yeah as long as its ddr. 333 and 400 are the speeds. the ram will only go as fast as your motherboard allows. i have a sd 2700 512mb on a 333mhz board. it wont go 2700 but instead slows down to 333

You might be better off going to Crucial.com or one of the other good memory sites and letting them test your machine.  They can tell you exactly which configuration will and won't work on your motherboard.  It's possible to save a lot of money by getting an expert's advice on that.

Well it depends on what type of RAM you have, not what OS you have.  Check out www.shopper.com or www.pricewatch.com for the latest RAM prices for your type of memory.

Yes of course!  You can install different RAM modules for as long as the have the same model (or speed or timing) to be safe always use the same brand - for example you can use varying capacities of PC2700 DDR and have them installed on your machine.  Your system will simply add them up together...

the brand is irrelevant except that it indicates the quality of manufacturing and therefore the price.\n\nyou must first check what the max memory is for your machine from the user guide. the guide will also tell you the specification of the memory modules like:\n\n- no. of available expansion slots (usually 1 or 2 in a laptop)\n- basic technology e.g. sdram, ddr, rambus\n- number of pins e.g. 168 pin\n- ram speed e.g. 133 mhz or 533 mhz\n\nit's first about matching the right specification and then deciding which brand you can affford
