It is a type of system memory, called RAM (Random Access Memory)
Kingston is the manufacturer, or brand
Valueram is the product line, or model
2 GB means 'Two Gigabytes', or 2,048 megabytes
800 MHz is the RAM's speed.
DDR2 is the technology, 'Double Data Rate 2'.
PC2-6400 is a way of repeating speed, type, and tech. PC2 means 'DDR2' and -6400 is the speed (6400 MB/s, or 800 MHz. 100 MHz = 800 MB/s for DDR2)
CL5 is the 'CAS latency'. This is how quickly the ram responds. It is a second method of measuring speed. The frequency (800 MHz) is the 'top speed', while the CAS latency is the 'acceleration'. What this means is that the computer needs 5 cycles to prepare every read or write, before it begins to do so (at 6400 MB/s). Lower CAS latency means faster response time. Generally, the frequency (MHz) is more important than CAS. But if you have two types of RAM with different CL and the same frequency (MHz), the one with the lower CL will be faster. CL5 and CL6 are standard DDR2 speeds. CL5 is considered 'good'.

What is the speed rating in mhz for a dimm that has a PC rating of pc2-6400 what type of dimm is assigned a pc2 rating?
800MHz and DDR2 is the assigned DIMM
Which of these would describe a stick of DDR2 RAM that has 8 eight-bit chips operating at 800Mhz each?
PC6400 DDR2 memory runs at speeds 400 MHz or higher, which is where DDR memory left off. Popular modules of DDR2 memory at the time of this writing are PC3200 (400MHz), PC4200 (533MHz), PC5300 (666MHz), and PC6400 (800MHz).
Which is better Kingston ddr2 ram or corsair ddr2 ram?
Depends of which you want, I want consider one being better than the other.
What is a good memory module by kingston that is under $500.?
Kingston Technology 1 GB DDR2 SDRAM is great and has good ratings
What is the bandwidth supported by a 200 pin SODIMM module?
200 pin DDR2 SODIMM is likely going to be between 200-800mhz in speed.
When you upgrade RAM is it possible to buy a 4 GB kit and use it with an already installed 4 GB kit to get 8 GB RAM?
As long as they're the same type (DDR2, DDR3). The speed of the RAM should either be the same or higher than your original since the computer matches all installed RAM to the lowest speed. e.g. my computer currently has a 2GB 800MHz DDR2 as well as a 1GB 667MHz DDR2. But the RAM is set to 667MHz and isn't utilising the full 800MHz on the 2GB.
What are some popular brands of PC2 5300 DDR2 memories?
Some popular brands Of PC2 5300 DDR2 Memory are PNY Optima, Kingston, Hynix, and Crucial. These DDR2 Memory upgrades can help make a computer perform tasks faster.
Do Kingston Technology memore modules only work on certain laptops?
Kingston memory modules will work on any laptop, provided it's of the same memory type (DDR, DDR2, &tc.).
What are some examples of companies that produce 1GB sticks of DDR2 RAM?
Most of the manufacturers of DDR2 RAM now make 1Gb sticks for it. They include Samsung and Sony as well as Hynix and Kingston. These are all widely available.
Can you use DDR2 5300 on DDR2 800 motherboard?
Yes. They are backwards compatible. Even with the installed 800MHz ram It will still only run at 667MHz speeds.
what models will the 2GB DDR2 SO-DIMM Upgrade for Acer Aspire Notebooks fit?
The Kingston memory 2 gb will fit the Acer models and many others as well.
What does 4gb ddr2-800mhz sdram mean?
