Q:I have a Dell Dimension 8400. I want to take out the memory and add 3GB of higher speed memory. These Crucial 1GB modules seem to have the same specs as memory which Dell says is compatible with my 8400. Yet Crucial's Memory Advisor says this module is not compatible. Is this correct?
A:Only PC2-5300 modules will work in this system:
Q:What does the 6400 stand for
A:PC2-4200 (DDR2-533), PC2-5300 (DDR2-667), PC2-6400 (DDR2-800), and PC2-8500 (DDR2-1066) memory are all types of Double Data Rate, second-generation SDRAM, usually referred to as DDR2. The varying numbers refer to the different speeds of memory your computer was designed for. PC2-6400 (DDR2-800), which has a bandwidth of 6.4GB/sec and is designed for use in systems and motherboards that require a 400MHz front-side bus, with an effective front-side bus speed of 800MHz.
A:Its referring to the speed of the ram itself in technical terms mostly labeled on the packaging of the item. A dimm module for example a 2gb 800mhz 240 pin PC2-6400 is clocked at 800mhz so the 800mhz is multiplied by 8 bit (smallest digital character) which equals 6400(800x8=6400), same thing goes for a dimm(ram) which is clocked at 667mhz then this would be 667x8=5336 but on the box of the ram you'll see PC2-5300.
A:The 6400 is basically the speed that the RAM runs at. Not sure what the speed is measured by (GHz or MB ect) but naturally the higher the better, however, if you are installing more RAM into a computer then the RAM will only go as fast as the slowest RAM already installed.
The memory I need has been out of stock for a really long time. Is there anything else that will work? Is there any way to cross reference Crucial kit part numbers (often available online at newegg.com or amazon.com) to be sure they are compatible before purchasing?
My data report came back as:
System specs as shipped by the manufacturer.
Scan your system to view your specific configuration
Maximum memory: 2048MB
Slots: 2 (2 banks of 1) [240-pin DDR2 DIMM Banking] and 2 (2 banks of 1) [184-pin DIMM Banking]
*Not to exceed manufacturer supported memory.
Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.
DDR and DDR2 modules can not be utilized at the same time. Each memory type is supported seperately.
Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.
Problem is, what RAM do I order?
I currently have 3 gigs, so I think I needjust 1 2 gig block to match the other 2 gig, to get the max 4 gig output.
I dont think using the other slot pairing would work.
There are 4 possible upgrades for this PC:
The only difference I can detect is the choice among specs denominated as Cl-11, CL-13, 9-9-9-24, or 10-10-10-30.
Can anyone explain their significance. PC wil be used as stand alone single user client device.
Many thanks for advice.

now giving up... !!!!!
I plan to upgrade the memory of my netbook ASUS Eee 1015PX to 2GB. From the factory it has one Hynix HMT112S6TFR8C-H9 memory.
I used the tool on your website to identify the required Crucial memory. It recommends:
2GB DDR3 PC3-12800 Unbuffered NON-ECC 1.35V part #:CT5630031
for the upgrade.
According to the description, that is 1.35V memory, whereas the Hynix memory is 1.5V (+/- 0,075V).
Will the Crucial memory work in my machine?
