I have an E Systems 3115 laptop and have a few questions which they cant answer for me:

It has 1 gb memory installed. Having taken the back off the laptop I cannot see any and believe it may be onboard memory, is this possible? Have never heard of this before.

I ran the crucial memory checker and the results were this:

Maximum Memory Capacity: 3145728 MB

Am I right in thinking this means I can fit 3gb in the machine?

Lastly, the alleged already installed memory is DDR2 533. If I was to fit 667mhz memory, would it run at the slower of the two speeds?

Thanks
