Here is my system specs. (For motherboard details, click here)

I want to upgrade my systems memory.

enter image description here

As you see on item specs page, this mainboard supports non-ECC, un-buffered memory.


Now, I got a question about this mainboard:

  • What if I buy a 2GB 240-pin DDR2 PC3200 400MHz ECC REG RAM module ? Will mainboard support this? I mean, will the mainboard support ECC memory modules? Please explain why you think so.

  • What about 2GB 240-pin DDR2 PC5300 667MHz non-ECC memory?

  • Explain to me what the difference between non ECC and ECC memory modules is.

Please specify the make and model number of the RAM instead of linking to an eBay auction. Secondly, to make this question more useful, please specify which specifications of the RAM module you're concerned about. Otherwise, this becomes a "will this specific memory module work with this specific mobo?" -type question, which is far too localized IMO. – Lèse majesté Apr 20 '12 at 15:27

  1. You can use error-correcting code (ECC) memory in a non-ECC motherboard. Obviously, the error correction functionality won't work.

    However, the first RAM modules presents two problems:

    • The RAM is also registered. It might work, but there's no guarantee.

    • It has only 400 MHz clock speed, which won't be enough for the CPUs that fit in your motherboard.

  2. Perfect fit.

  3. ECC memory can detect errors (such as single bit flips) that may cause a system crash or data corruption.

    For more information, I suggest you read the Wikipedia article ECC memory.

Oh.. really confused. Answer 1 says there is no chance that 1st link will work. You say it will work. 2nd 2x more expensive then 1st. – Tural Aliyev Apr 20 '12 at 15:11
I just said that ECC memory in general will work. The first RAM module is registered and too slow. So no, it will not work. – Dennis Apr 20 '12 at 15:12
@TuralTeyyuboglu My bad, I confused ECC and registered RAM. Dennis is correct, ECC memory will work in a non-ECC motherboard, the error correction will simply be disabled. – Indrek Apr 20 '12 at 15:13
What about this one ? Or, please look at this search result (Select Azerbaijan if the shipping window will pop up) . Please advice some 1x 2gb memory module with MINIMUM price that fit with this MB. Thx in advance – Tural Aliyev Apr 20 '12 at 15:17
The first memory is fast enough, but it is registered (REG). It might work, it might not. Any 240-pin DDR2 memory with sufficient clock speed that is not registered will do. What CPU do you have? – Dennis Apr 20 '12 at 15:22
