Are there different types of DDR2 RAM?
PC2- indicates the module uses DDR2 memory; PC- indicates the module uses DDR memory. Other common speeds for DDR2 SDRAM modules include PC2-3200 (DDR2-400; 3200Mbps throughput); PC2-5300 (DDR2-667); PC2-6400 (DDR2-800); and PC2-8500 (DDR2-1066).
What happens if RAM is faster than motherboard?
Your computer will work just fine if you install the faster RAM. It will simply run at the slower 1333Mhz speed. Your motherboard will recognize those faster RAM sticks as being compatible (because they are) and allow the system to boot up and operate normally after you install them.
What does PC2 5300 mean?
DDR2 PC2-5300 (commonly referred to as DDR2-667) memory is DDR2 designed for use in systems with a 333MHz front-side bus (providing a 667MT/s data transfer rate). The “5300” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 5300MB/s, or 5.3GB/s.
What is the difference between ECC and non-ECC memory?
The failure rate of non-ECC memory is higher than that of ECC in the past 3 years. The main cause for non-ECC memory failure are memory errors, incorrect size/speed, and misc. Reboot during the memory test is the primary reason for the ECC memory failure.
Does ECC RAM work on desktop computers?
Though most server and workstation motherboards require ECC RAM, the majority of desktop systems either work at all with ECC memory or the ECC functionality is disabled. According to tests, ECC RAM is slightly slower than non-ECC RAM.
What is ECC (error correction code) memory?
Error Correction Code ( ECC) memory, a kind of computer data storage, can detect and correct n-bit data corruption. That is to say the ECC memory can protect a memory system from being affected by bit errors. The ECC memory is often found on workstations and servers.
How much does ECC affect performance?
Using ECC decreases your computer’s performance by about 2 percent. Current technology DRAM is very stable, and memory errors are rare, so unless you have a need for ECC, you are better served with non-parity (non-ECC) memory. ©2019 Micron Technology, Inc.
