is a table providing information on the different types of DDR
motherboard's manual provides the information on the types of
RAM that the motherboard can run. You must set the RAM clock speed
(in the BIOS, or by setting jumpers on the motherboard) to the
speed of the RAM that your purchase. This is 133MHz for PC2100
and 166MHz for PC2700 DDR RAM.
it matter which slots I plug my new module in?
general, you will get the best performance if you put the largest
module (in megabytes) in the lowest-numbered slot. For example,
if your computer comes with 256MB of removable memory and you
want to add 512MB, it would be best to put the 512MB module
into slot 0 and the 256MB module into slot 1.
Does the Price of Memory Fluctuate?
and demand. Occasional changes in market demands will alter
inventories and, therefore, raise or lower prices.
you mix and match ECC and non-parity modules?
When adding new memory, you need to match what is already in
your system. You can determine if your system has parity by
simply counting the number of black memory chips on each module.
Parity and ECC memory modules have a chip count divisible by
three or five. Any chip count not divisible by three or five
indicates a non-parity memory module.
DDR and SDRAM be used in the same system at the same time?
Even though there are systems that support both technologies,
you can't have DDR and SDRAM in the same system at the same
time. You'll have to choose one or the other.
You can use some of the easy tools to find your exact DDR or DDR2 Memory Upgrades for your Desktop, Laptop or Servers.
Use the Memory Selector to find compatible DDR or DDR2 Memory Upgrades, or the all new system scanner tool to scan your system to find exact matching DDR RAM. If you need more help use the Live Chat Support
