Vista Home basic will not install with 2 Gigabytes of ram

[grandpa_simpson]

I had 1 Gigabyte of ram installed on my computer.  I recently added another Gigabyte so now I'm running in dual channel mode, and obviously have twice as much memory.

I had to reinstall Vista (home basic) and could not get it to work unless I removed the extra ram module.  I don't remember exactly what the errors were, but they prevented Vista from installing.  After the installation I added the module back in and it works fine.
 
Is this a ram compatibility issue ?

If so, how do you find compatibility lists for OEM motherboards, if there are any ?  This is an eMachines T5088

The ram I'm using is  Corsair DDR2 533 MHz, 1 Gigabyte each.  Part # VS1GB533D2

Why did you need to reinstall Vista?

I'm not sure what happened.  But after I added the new ram Vista crashed shortly after booting and running some apps.  I tried restarting but it was no good.  Tried last known good configuration and it said the Vista kernal was corrupted and vista failed to start.  A start up repair with the vista recovery environment disc was unable to fix it. 

I had linux dual booted with Vista and even linux would not boot up.  I ran memtest86 and ran hard drive diagnostics and the memory and hard drive turned out ok..

Wow,, well Vista and ubuntu on the same hard drive is not what I would chose. I have seen to many boot issues with them on the same drive since they usually share the same MBR.

You can run a full repair install of Vista from the DVD and it may overwrite the MBR at the same time leading to more issues fixing that.

Not sure if you have back ups of files from both OS's or not but you may want to start fresh to save time and effort. (and put ubuntu on another hard drive)...just a thought and my advice from experience.

any more info to add, developments?
