do you know any benefits from DDR to DDR2?

DDR2 has a faster data rate, faster bus frequency, it uses less voltage, it's prefetch size is 4 bits instead of 2bits that regular DDR has. It's all around faster.

Your new RAM must be DDR2...Besides, nothing else will fit as DDR2 has 240 pins, DDR has 184 pins and older SDRAM has 168 pins (for desktops anyway...laptops have a different number of pins than desktops, but each type still carries a separate number of pins from the other types).  Use the recommended speed as Dell computers are built only to handle a certain speed and, generally, are not upgradeable much less downgradeable.  Using memory of a different speed can cause your computer not to boot up and could possibly cause damage to the memory and/or motherboard.  Placing them in pairs is not absolutely necessary nor is using identical memory size chips, however, if you do use 2 sticks of identical memory, it gives the added benefit of using Dual-Channel which significantly enhances the performance of your memory and processor and, thus, your whole system.

There are no 2Gig RAM in a single module except for servers. A high quality DDR PC3200 1 Gig module is around $100, although the highly rated Corsair Value select is only $77 for a gig. Very cheap compared to the old days!

The GamePC website has this to say.\nhttp://www.gamepc.com/labs/view_content.asp?id=noconaopteron&page=4&cookie%5Ftest=1\n\n"For those who are wondering, DDR-2 slots are not backwards compatible with DDR."

Yes. DDR 2100 equals to DDR266. Its not DDR2100, but PC2100. 2100 is the thoroughput/bandwidth, 2100MB/second, and 266 is the speed (266 MHz effective, 133MHz X2 because its DDR (Double Data Rate)). So its PC2100 and DDR266. Don't mix them up.\nDDR333 is PC2700, and DDR400 is PC3200.

don't do it. slows stuff down. RAM is cheap. if you use multiple sticks, match by size, speed and manufacturer.

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.

2GB is the most memory your machine can handle

Not unless you're gonna be overclocking your computer.\nBut if you're not, get memory with the same specs (at least): DDR2 PC2-3200. Before you do, check to see if you can add memory. If you can add memory, buy memory of the same brand and model (other brands/models are likely to have different timings, causing all sorts of problems).

as long as it's DDR you'll be fine ... even if it's faster DDR like for example PC400 it will still "clock back" to the 266 that your board uses ....

I've played DDR for two and a half years now, since it first entered the local arcade.\nI play it for about two hours a week, on Heavy mode, up to the easier ten-footers. I haven't noticed a huge weight loss, but my calves are in really great shape, lol. I've also noticed that my endurance and reflexes have improved dramatically.\nI recently bought a home version (Ultramix 2) and the home-style pads, which includes a calorie-burner mode and a special exercise mode. Those are very helpful, to get some definite exercise in.\n\nI also play In The Groove whenever I get a chance, and it has much longer songs, much harder difficulties (up to 13 feet, I believe) and bigger pads (which is good, I'm tall). If you get a chance to play it, try this game out - it's great.\n\nIf you're looking for a little fun exercise, it's a great game. There's a huge fanbase all across the world, you can find someone to do it with, and it's really entertaining to watch how fast your feet can really move!

Whenever you upgrade your memory, you should take into consideration the number of slots you have,\nwhether you plan to upgrade again in the future, and the current prices for memory modules. Because\nthe memory market can fluctuate quite a bit, it is sometimes less expensive to purchase a higher\ndensity part, like a 128MB module, while at other times it is less expensive to purchase two lower\ndensity parts, like two 64MB modules. If you are planning to keep your system for several more years\nand think you might want to add more memory later, look at how many open slots are left in your\nsystem. If you have quite a few open slots, it probably doesn't matter whether you buy the low- or\nhigh-density modules. However, if you only have one or two open slots left, you may want to purchase\nthe higher density module now.

Speed and type of RAM used is dependent on the chipset used to make the mainboard. \n\nIn your case, the answer is "no way". DDR2 didn't exist back then except in a lab.

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.

The latest are DDR2 memories equipped with a crucial chipset. They are really fast, but you'll need passive cooling to support them. For mor einformation check this link:

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...

Makes no difference.\n\nThe only thing it affects is the price as 2*1gb would cost more.
