    Post What does the PC(number) mean in RAM

    What does the PC100 PC133 Mean in ram? Ive high numbers for very cheap prices. Oh yea, and do I need ECC, the error checking stuff?

    PC100 = 100Mhz
    PC133 = 133Mhz

    It's the speed the memory runs at.

    And ECC isn't necessary at all. Save yourself the money and buy non-ECC. Some mobo's do require it, but those are usually more expensive and are meant for servers.

    So would that mean that RAM running at 1600MHZ would be really cool?

    PC1600 is the DDR type of ram, and that requires a specific type of motherboard with specific types of memory dimm slots.

    Effectively there are 3 types of memory out there (4 if you count ECC):
    1. SDRAM: This includes PC66, PC100, PC133, and PC150. These numbers are supposed to relate the max bus speed that they run at.

    2. RDRAM (aka: Rambus): PC600, PC700, PC800 are the designates on these types. This system memory is used onthe i820 and i850 motherboards from Intel. Almost twice as much $$$ than equivalent SDRAM.

    3. DDR (Double Data Rate): A new specification that is going to be in full swing, likely by months end. It is designated by PC1600 and PC2100. These represent the theorhetical throughput of the memory (PC1600 = 1.6GB/sec, PC2100=2.1GB/sec).

    So, speed used to be the way memory was sold, but now it is a marketing game. Make sure you understand what you are buying before you plunk down your hard earned cashola!
