PC2100 DDR Memory question

[biggestmuff]

I'm putting together a new pc with the ASUS A7M266 and a 1.2 GHz TBird. I'll be putting the PC2100 memory on the board and have found a few different types of memory. What's the difference between Unbuffered non-parity and registered ECC? What's the difference and which kind should I get? Thanks!

From what I've heard ECC (Error Correction Code) RAM is meant for servers. It is a little more stable, but costs more and is slower. For home use, the "Unbuffered non-parity" stuff is fine. It's what's included in all home computers from companies like Dell, Compaq, Gateway, and so on.

<< Description:

What is the difference between ECC and non-parity memory?

Solution:

ECC is indicated by a 36 or 72 in our part number. Non-parity is designated with a 32 or 64. If you already have a PC and are unsure which type you have, count the number of black chips mounted on one of your existing DIMMs. If the number of chips is evenly divisible by three, then you need ECC. If the number of chips is NOT evenly divisible by three, you have non-parity memory.

If you are building a PC and deciding which type to use, the following guidelines should help. If you plan to use your system as a server or a similar mission critical type machine, it is to your advantage to use ECC. If you plan to use your PC for regular home, office, or gaming applications, you are better off with non-parity.

ECC (error correcting code) memory performs &quot;double bit detection and single bit correction&quot;. This means that if you have a single bit memory error, the chipset and memory will find and repair the error on the fly without you knowing that it happened. If you have a double bit memory error, it will detect and report it. Using ECC decreases your PC's performance by about 2%. 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 SDRAM.

You can use both types in that board of yours,but I would go with un-buffered it`s cheaper and slightly faster.

Kudos to the fast responses. I'll be picking up some non-parity then!
