Max memory on Asus M2N-MX SE?

by dugouha / August 5, 2009 2:25 AM PDT

Hello everyone,

I currently have 1x1GB DDR2 and I'm thinking about upgrading my RAM and making it dual channel, but I'm not sure about the max memory for my mobo (Asus M2N-MX SE).

According to the User Manual ( http://dlsvr01.asus.com/pub/ASUS/mb/socketAM2/M2N-MX%20SE/e3168_m2n-mx_se.zip ) it supports 2x1Gb, i.e. 2Gb total.
The same specs are on Asus' site:
"Dual channel memory architecture
2 x 240-pin DIMM, support max. 2GB DDR2 800/667/533 ECC and non-ECC,un-buffered memory"
( http://www.asus.com/product.aspx?P_ID=LqXTJVvWNyI6cj2d )

However, I've seen many reviews which state that it supports up to 4Gb DDR2 (2x2Gb), and The Crucial Memory Advisor? tool says the same.
( http://www.crucial.com/store/listparts.aspx?model=M2N-MX%20SE )
Now I don't know who to believe...

The question is: can I upgrade to 2x2Gb (2 x KVR800D2S6/2G)?
or should I go for 2x1Gb instead?

In case you need it, here's the CPU-Z report:

Thanks in advance!

Al I can add is

The nVidia nForce 430 MCP does support that much memory. Crucial is pretty good about it but WOULD YOU BE UPSET if Windows reported 2.75GB RAM?

Your choice here.

The manual and any "updated release addition" to the manual is the final word. Plus, you truly need to verify you're getting the correct mtrbd. info when at the support website, the version# and rev". The website usually has the latest word.

Crucial has made mistakes as there are so many variations and types of mtrbds. out there. Generally though it has been correct, but I have found some, like 2 ram slots vs. 4 slots(only 2 slots present).

Now, you can install the 2x2gb of ram but it may only see 2x1gb of ram. That maybe the result of not having the latest bios update and/or it supports ONLY 1GB per slot period. Alas, DDR2(if optionable) mode may need to be enabled as well for best operation, if not already. Play it safe and buy the 2x1gb of ram.

When I entered Asus M2N-MS SE(what you provided in post), I got:

http://www.google.com/search?q=Asus+M2N-MX+SE&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a

I got that listing but please notice that the 1st two hits show a listing for a "PLUS" version, so be sure what you got. While there is a Nvidia chipset present, Asus may not use the full-blown capabilities that chipset provides as the maker has that option to do so, its just their version. Which may result in 2x1gb ram vs. the 2x2gb install issue.

If Crucial says it will work and you purchase RAM for your

specific system (or motherboard) from Crucial...believe they will guarantee it will work or $$ back. Please check to confirm that before buying.

If you really need 4GB...I'd try it thru Crucial. If it doesn't work, return it and get another 1GB DIMM (matching the original if possible is best). Not much gain for most going from 2GB to 4GB

Let us know how it works.

First, thank you all for replies.

@Willy: Yeah, unfortunately M2N-MS SE with only 2 slots is exactly what I've got... Wink

I did some googling today and found out that M2N-MS SE *PLUS* apparently takes 4Gb, but even so, Asus recommends "total installed memory of less than 3GB" for reasons Bob mentioned.

@VAPCMD: Thanks for the tip! Alas, buying through Crucial is not an option, since I don't live in the States, and the shipment costs and possible customs fees would outweigh the MBG benefits.

So... I've decided to stop being greedy, listen to your advice and and go for a new 2Gb kit (2x1Gb) to get dual channel.
Since this PC is not used for heavy duty stuff, and I just want to speed it up a little, guess that'll be more than enough.

Thanks again for taking time to respond - you've been really helpful and I appreciate it Happy

Not that it makes much difference, but today I had problems with bios update. I tried first via ASUSUpdate, which I have used in the past, then using afudos, then EZ Flash... no use...

My current bios model is wrongly named M2N-MX (according to the new bios changelog: "Correct the product name under ASUS Update->Check BIOS Information."), and I'm unable to flash it to the latest version which is labelled M2N-MX SE...
Anyway, since changelog doesn't say anything about DDR2, and my version is working ok, not to mention the fact that i'm unable to flash it, I valiantly gave up on the idea.

Taking all this into account (plus this MB's chronic problems with USB) I'll just try to stay away from low-end Asus mobos in future.

Cheers!

Your actions to not continue the bios update is correct. However, if I understand you right you mentioned M2N-MX as the bios update, that's incorrect. You stated you have M2N-MX SE which the bios update you need. Which is why I mentioned in my earlier post to be sure what info to be gotten refers to the correct mtrbd. relating to the ram issue. These aren't necessary cross-exchangeable. The whole M2N listing is long so any future support website visits take heed.

And that's where the things get interesting...

Willy, I DO have M2N-MX SE here's the box, and I can assure you that the same thing is printed out on the mobo.
http://i26.tinypic.com/5x1uhl.jpg

However, for some unknown and mysterious reason, that mobo came with BIOS Version 0406, which, according to the ASUS site again, was eroneously labelled M2N-MX:

BIOS version: http://i26.tinypic.com/2hi8lkg.jpg

Asus site with updates: http://i29.tinypic.com/20mhdz.jpg

Now, when I try to update to v.0501 which has that name "error" corrected and is correctly labelled M2N-MX SE, I get the following:
http://i30.tinypic.com/33lphfc.jpg

and the update won't continue...

The current BIOS doesn't come with EZ flash 2 (there's no "tools" menu in bios) so I can't update from a pendrive, and EZ Flash doesn't recognize the new bios (v.0501) from a CD (I don't have a floppy drive).

Anyway, that's a whole different story altogether... and one that doesn't require a solution at the moment.

I apologize if I hijacked my own thread, I just felt the urge to explain the situation in detail Happy

Regards!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
