This question is similar to the following: But asking the broad question of who to believe when seeking memory upgrades?

What will happen if I install more RAM than specified in manual?

What happens when more RAM is installed than the motherboard supports?

An MSI-7309 (K9N6SGM-v) Has (2) slots to fill. I am not exactly sure of the capacity.  Included below are links to conflicting specs.  I know that it can hold at least 2 Gigabytes. I would like to get 4GB in there. Without having to pay for return shipping or a restocking fee.

2GB

The motherboard manufacturer latest manual version.

Please see that the BIOS section specifically notes memory installs of 4GB located here: http://www.msi.com/product/mb/K9N6SGM-V---K9N6PGM-FI---K9N6PGM-F.html#/?div=BIOS

The manual was last updated in 2006, while the BIOS was last updated in 2008. I would assume then that the manual and newegg were never updated to reflect the newest memory availability.

Hope this helps.

But is it possible that the Spec page for the board is trying to be too general, and apply to all the boards in that series? I saw that firmware update changeLog you mention. That seems to indicate that the reporting of what amount of memory was recognized. What about the memory config sites? –  TheSavo Feb 14 '12 at 16:16
    
Even if the BIOS was updated to accept more RAM, probably the mobo hardware was not. –  m0skit0 Feb 14 '12 at 16:32
    
It's possible, yes. But I'm willing to bet that around 2006-2007 2GB memory chips were not in the norm, and a BIOS update was needed to get that memory available to that system. It looks difficult to get very specific results for this, I don't think with my google-fu we're going to be able to determine verbatim if this is possible. –  jidar Feb 14 '12 at 16:38
    
Also keep in mind that the memory controller for these boards was on the CPU, not the mainboard. Hence BIOS changes allowing for more memory as it was not a CPU limitation. –  jidar Feb 14 '12 at 16:40
    
@jidar. So would looking @ the stats of the processor be more helpful? –  TheSavo Feb 14 '12 at 17:29
