XL201 - How much RAM supports?

[d8b]

Hi all,

Sony say 3GB, but crucial.com say 4.

What is the truth?

[Nobody-in-particular]

I would go with crucial as they guarantee the RAM's compatibility

[d8b]

So have you installed 4GB?

It's 3Gb in the userguide available from Club Vaio. Last week Crucial didn't even recognise the VGX-XLxxx series on their search tool, so don't trust them! 😉

3GB max for sure.

Thanks Chalky,

I bought 2x1GB.

What is the truth?

The truth is that Windows XP and Vista (32bit) can only use 3GB and a little bit more. No problem, to put a 1GB module into each of the 4 memory slots.
If you want to save money, put 1 x 1GB and 1 x 512MB module into each memory bank. That gives you the maximum of 3GB and provides dual channel memory access.

Thanks FHB,
I installed 2x1GB on the empty slots.
So, my configuration is 512-1-512-1
it might providing dual channel memory access.

Hi d8b,

Crucial.com are normally spot on with there Crucial Memory Advisor™ tool..

However I am unable to find any reference to the VGX-XL series on their site..

Hi Thalamus,

adding 2GB in my opinion is the best solution.

Otherwise you have to remove the 512MB dimms.
