I purchased this kit and installed both of them quite easily. I immediately noticed a huge speed increase and no more freezing up or moving slow was identified. This product arrived quickly and well packaged. The customer service was fantastic. I highly recommend Crucial for ram.

If all this confuses you, then I recommend going to crucial.com from the computer you intend to upgrade and find the Crucial Memory Advisor(tm) tool. Click on "scan your computer" at the bottom of the window that contains the advisor. And remember this:
1. There are different generations of DDR (or double data rate... the new standard) memory. There's DDR1 (simply referred to as DDR), DDR2, DDR3, DDR4, and DDR5 (I believe DDR4 and 5 are used primarily for high end video cards at this time - late 2010). Find out (for SURE) what generation of DDR RAM you are using, as the different generations are not compatible with each other. The memory stick would not fit in your machine..
2. Rather a memory stick be too fast, than too slow. example: 667Mhz memory installed on a motherboard that supports 533Mhz memory will auto adjust the memory to 533Mhz, and will work fine. But 533Mhz memory sticks designed for boards that desire 800MHz sticks means your memory will have to work above and beyond what it was intended for.. So even though they're both (let's say) DDR2, you could run into serious problems if your memory isn't as fast as it needs to be.
3. Make sure the pin count is correct. DDR2 is a 240-pin module. DDR is a 184-pin module. Notebooks have 200-pin modules for DDR and DDR2, however the notch on DDR modules is in a slightly different position than that on DDR2 modules. Don't buy mobile (laptop) memory, if you need memory for a desktop, and visa versa. Mobile memory example: PC2-6400 DDR2 SO-DIMM (for notebooks)
4. If "kits" and "dual-channel" confuse you, then you should probably buy kits (kits are identical pairs). If your computer NEEDs dual channel memory (a FEATURE), and doesn't receive it, it probably won't run. But if your computer will run memory that is not identical, then the kit will not hurt anyway. Make sense?
5. I believe most home computers use non-ECC (error correction checking). unbuffered memory, because it is much more cost effective. Servers use ECC, buffered, because it's mission critical.
6. "What's this PC2-5300 stuff?" ... without a long explanation, just divide the last number by 8 to find out the actual speed of the RAM. Multiply the speed by 8 to find the bandwidth (in MB per second). Some shops display only bandwidth, and others only speed. Hence, PC2-5300 is DDR2 667MHz (give or take a few MHz, which is allowed). Likewise PC3-10600 would be DDR3 1333MHz (even though it comes out to 1325MHz...) Make sense?
If, after all this, you still have reservations, then I would recommend letting your local computer geek (like myself, were I in your neighborhood) have a look at your machine. A RAM memory upgrade is actually a relatively simple process, to someone who follows computer technology on a regular basis (and preferably worked with more than just one machine).
Wow. My review turned into an instruction manual...

I started using the windows processor/memory widget and quickly realised during the times of solid hard drive activity the memory usage (2GB total) was close to maximum but the processor (AMD Athlon 64 X2 4200+) was only around 30% used which made me think that swap files are the issue. I duly invested in 4GB of Crucial Memory which was fitted in a couple of minutes and the computer now runs really well with hard drive activity significantly reduced.
For the cost of around £50 if I get another 12 months of non-frustrating use out of the PC it is will be well worth it, however if I experience any issues such as BSOD I will report them here.
For info the motherboard is an ASUS M2A-VM HDMI for anyone with the same who is wondering if the memory is compatible.
(Maximum allowed in two slots provided). Came quickly, worked perfectly.
Decided to upgrade my Home/office spec HP XP Pro PC from 2 x 500 Mb to 4 x 1 Gb in four slots provided.
Used Crucial scanner to determine exact DIMMs required. Couldn't find these on Amazon so ordered from Crucial direct.
Same speed of delivery and delivery cost (zero) and price difference not worth worrying about.
Ordered two 2 x 1GB upgrade kits.
Installed, worked, but My Computer, Properties, General showed only 3 Gb memory.
Before trying permutations of only two DIMMs to see if 2 Gb showed and thus eliminating any possibility of faulty DIMM (unlikely) I telephoned Crucial support.
Having ascertained that I had 32 bit Win XP Pro , they explained that I had fallen into the 3 Gb switch trap. I leave you to research this, but (simplified) without making BIOS changes and worrying about video card memory overlap questions, the 32 bit version of XP limits RAM to 3 Gb.
They explained I could get 3 Gb by using two of my new 1Gb DIMMs in the primary slots and putting my existing two 500 Mb DIMMs in the secondary slots.
I said it was a pity then that the technical info on the PC had led me to buy twice as much memory as I needed.
No problem they said, emailed me a returns code, I sent it back and they promptly (presumably after checking the memory) have refunded half my outlay.
So, as other reviewers have said, "crucial to buy Crucial". It works and they know how to treat their customers.
This Crucial DDR2 is not one of those exciting memory products with cooling fins, colourful designs and a name more suitable for a dodgy sports car or something worrying from Anne Summers. It is very unexciting, exactly as it should be. You stick it in the slots, close the case, and your PC works as desired for years and years.
I bought this to upgrade an old PC which had 2GB of good quality PC2-5400. Replacing it with 4GB of PC2-6400 brings a very obvious improvement, especially when running image editing software or other apps which cache large amounts of data. The PC no longer swaps to disk even under load so this is a major improvement. It also lets me allocate a bit more system memory to the PC's integrated graphics so I can play silly games with better settings.
I see that some reviewers feel the price is too high but actually it's pretty decent for good quality RAM. Using cheap RAM, as often found in generic or home built or own brand PCs, is an invitation to unreliablity and instability and almost never the bargain it can seem.
More RAM is probably the best upgrade available for many older PCs and I think this Crucial product is of good quality and reasonable value.
I have had Word, Excel, Access, Media Player, AutoCAD, plus a couiple of minor graphics programs and up to 7 active tabs in Internet Explorer all running at the same time and the PC barley falters. Ram has to be upgraded in matched pairs so I had top buy another 2GB to get best performance from the RAM upgrade. Crucial do a RAM checker to see what your Motherboard and exisitng RAM are to make sure you get the right RAM for an upgrade. THe Crucail web site says one price, while Amazon sell the same product from Crucail at a slighlty lower price. Use sopme common sense here where you buy it from. My order arrived after 3 working days. Packaging was not good but it survived and worked fine out-of-the-box.
My bottom line line here is that my RAM upgrade WAS worthwhile (even if 1GB appears to be wasted) and my PC is performing better for it.
