ASUS A7V400-MX - Won't Recognise New Memory Modules

Hi

 

I have a custom built tower with an ASUS A7V400-MX motherboard, which had 2x500mb cards. I got 2 new 'Crucial' memory modules brand new in static packs, which were DDR (not DD2/3) and 1 gig each, which is what the manual says this motherboard can take max.

 

So I put the 2 new 1 Gig modules in and turned PC on and it started a slow repetitive beeping. Then took memory out and put one of the old 512mb back and this time it booted. Finally turned it of and put one of the new 1 gig ones in as well, rebooted and checked task manager and it only seemed to be using 500mb.

 

Can't work out why it won't recognise new memory. I checked upgrade for this motherboard on crucial site (link below) and it lists the memory module, but I noticed this said (NON-ECC) and the new mosule says ECC on it. Is it this that is causing the problem perhaps or is there something else I can do to check why it is not recognising?

Many thanks for any suggestions

If the board/system calls for non-ECC RAM...that's what you need to install.  The motherboard specs determine the proper type of RAM for the board to function properly.

Contact Crucial, return the purchased RAM for the correct modules...they are reasonable.

Swapped memory quite a few times between PCs and never heard of this EEC thing. Just to be clear so Crucial doesn't get a negative image they never supplied me directly, it was someone's old stock.

 

Thanks

If you use Google...you can read all you want about EEC vs non-EEC RAM.  In a nutshell...EEC RAM might be used by a server, while the vast majority of PCs use non-EEC RAM modules.

 

No point in having RAM which doesn't work with your motherboard, free or not, purchased, or otherwise acquired.
