Hi all, I've been browsing the forum watching several posts on Windows
Vista and 4Gb memory issues, but couldn't find a solution. I have a Sony
Vaio NR210FH. I upgraded memory to 4 Gb (2 x 2Gb). BIOS recognizes ok,
but Vista Home Basic doesn't start. If I only use one 2Gb, it works ok.
I'll be glad to reach the 3.5 Gb that other's complain about  ...
Anyone can help on this?

Hi,
Are they a matched pair?
Are you using dual channel memory?
Are the sticks the same speed?
How about if you swap their slots?

The "3.5" GB is not related to your issue. That refers to some of the 4GB
being reserved by the BIOS for memory-mapped IO and the remainder being
3.5GB or so.
What does Sony say? I take it that this model is available in Latin America
but not in the US.
Is the upgrade ram the same brand and latencies as the original ram? Was it
shipped to you by Sony?

Are both sticks exactly the same..... manufacturer/type/speed/class etc etc.

Thanks Collin!
Yes, indeed this Sony VAIO was purchased in Argentina. Originally, it
came with 2 Nanya NT512T64UH8B0FN (5300) of 512 each. This Vaio has 2
memory banks.
I purchased on Circuit City, 2 *CEN 2GB667LT Centon 2GB PC2-5300
(667Mhz).*
With only one installed (2 Gb.) works fine. When I place the second one
in the other bank, the BIOS recognizes the 4 Gb. ok, but Vista never
starts, puts a bluescreen and whenit tries to restart, goes to the
emergency start screen. None of the ways (safe mode, etc.) manages to
start Vista.
Kind Regards from Latin America.
Gustavo.

The fact that the BIOS sees it is no guarantee that it does not have an
issue when being accessed by software.
You mentioned that it runs fine with one stick but the second is the
problem. Call the first stick A and the extra stick B. Can you reverse the
sticks? Does it run with B in the first slot? If it works with B what
happens if you then insert A in the second slot?
Have you checked on the computer manufacturer's website for a BIOS update
that might address the issue?

A couple things to try, first off, have you tried each of the 2GB sticks
individually in slot 1? If that works, try either alone in slot 2.
Next, insert both sticks, and run MemTest86+ from
http://www.memtest.org/ and see if this yields any clues.

Thanks DevilsPGD. I've tried inserting the 2 Gb sticks on either slots
and the same happens. To do the other thing you suggest, I'll need to
boot my notebook somehow. With both sticks on, it never gets to start
Vista, so I don't know how could I run a memtest. Any guidance? Thanks.

Run the memtest on each stick individually. It's all you can do at the
moment.
