Memory spec terms
If you're not sure if a module is right for your system, use Memory America configurator for a list of guaranteed compatible modules.
NON-ECC/Non-parity — Most desktop and laptop computers take NON-ECC or Non-parity memory.
ECC/Parity — ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.
Unbuffered — Most PCs and workstations use unbuffered memory which is faster than registered memory.
Registered/Buffered — Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.
Fully buffered — Designed for next-generation servers, features an advanced memory buffer.
CL — CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.
Component configuration — (For example: 64Meg x 64) Indicates the size of the memory chip components on the module.
Voltage — For example 2.6V. Indicates the power used by the module. The lower the better.

- Return for refund within: 30 days
- Return for replacement within: lifetime
For a return for credit, this item must be returned to Memory America within 30 days of the invoice date for this policy to apply. For a replacement, we offer a Lifetime warranty and support on all memory upgrades. “Return” constitutes receipt of the product by Memory America, and not the mere issuance of an RMA.
The following conditions are not acceptable for return, and will result in the merchandise you have returned to Memory America being returned to you:
- Modules exhibiting physical damage
- Modules that are missing the manufacturer label containing model number, part number or serial number
- Modules that are missing the manufacturer warranty label
DDR SDRAM
Double Data Rate synchronous dynamic random access memory (or also known as DDR SDRAM) is a class of memory integrated circuits used in computers. It achieves nearly twice the bandwidth of the preceding single data rate (SDR) SDRAM by double pumping (transferring data on the rising and falling edges of the clock signal) without increasing the clock frequency.
With data being transferred 64 bits at a time, DDR SDRAM gives a transfer rate of (memory bus clock rate) x 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus, with a bus frequency of 100 MHz, DDR SDRAM gives a maximum transfer rate of 1600 MB/s.
"Beginning in 1996 and concluding in June 2000, JEDEC developed the DDR (Double Data Rate) SDRAM specification (JESD79)."[1] JEDEC has set standards for data rates of DDR SDRAM, divided into two parts. The first specification is for memory chips, and the second is for memory modules. As DDR SDRAM is superseded by the newer DDR2 SDRAM, the older DDR version is sometimes referred to as DDR1 SDRAM.
