Plz Help me...About SDRAM

Hi all,
    I have a Micron 512MB ECC PC-133 SDRAM,which has double sides with 9 chips in each.And my problem is that,it can't be fully used on my intel440BX mainboard.Only half capability of it,256MB,can be recognised.
    Anyone can give me a list of the popular chipests which support this Micron?Or anyone can suggest me how to solve this problem?
    Thanks to you*_^

Regards,
Reno

Any newer mobo that will still support SDRAM will support a 512M chip.  Do you know it is good?  Did it read 512M on the machine that it came out of?
Reno,

As far as i know, most Intel 440BX-based motherboards can only accept a MAXIMUM of 256MB module per bank. That is the reason why your 512MB module will only register 256MB.

If you want to use that module, you have to buy a motherboard that will support it. The only motherboard I know that will support such size is the Intel S815EBM1 (server board) otherwise, sell or return it and buy a 256MB module.

Next time when you consider buying a RAM upgrade, ALWAYS check your motherboard manual what modules it can use.

Personally, I like Micron (Crucial) modules. I consider them as the Mercedes-Benz in the PC memory industry. =)
Reading from my FIC manual (AZ11EA)

Accepts up to 1.5G DRAM using three DIMMs of 32,64,128,256,512MB with support for lightening-fast SDRAM (100/133MHz).

It sounds like this board will support your 512M SDRAM.
As far as i remember 440BX motherboards only support single sided ram. Basicly 1/2 of your ram is not working.

Great thanks to you all guys.I'll sell it then and purchase one 256MB later.
I considered that maybe I could buy one ServerWorks chipest which supports 512M,but it seems that Memorys must be employed in couple on mainbord uses that chipest,right?
Then the only thing I could do is to sell it,so pity :'(
Goodbye to this Micron though I do love it,sigh.
So who got the points =)
What do you mean,the modder?^^

Just FYI to the experts here:  Technically, none of you have the correct answer, though I do want your input here.

So you understand, having nine chips means this Memory has parity -  Which is not normally supported on any BX board.  It has nothing to do with double-sided/single sided or whether the board supports Max. 256 or 512Mb modules.  The fact is the board would possibly support a 512Mb NP and NON-ECC module, but it would most certainly not support an ECC Parity module, regardless of if it was a 512Mb or 256Mb module -   and that's the actual problem.

My inclination is to have it PAQ'd and refunded.  But what do you all think?
