Generally that limitation is a function of the BIOS. XP and Vista 32-bit are limited to 3Gb in any event, so you are already in pretty good shape. ... Thinkpads_User<br />

the design of the motherboard will be such that it cannot address chips larger than 1GB each.

The chipset is the final limitation since it restricts the number of RAm channels available. The OEM can make the restriction even smaller if they only supply a certain number of slots.<br />
<br />
No way around these limitations.<br />

I hope this helps !

The PHYSICAL memory limit for ALL Windows 32-bit OS's is 4 GB. --&gt; FOUR GB!<br />
-<br />
- Slightly less is -AVAILABLE- to Windows ,,, But the -LIMIT- is still 4GB.<br />
[That does not include Server versions that can use PAE.]<br />

Thanks!!! That's what was confusing me.. I knew the chipset would support 4GB, I couldn't understand what was limiting it. Many thanks ;-)

Why does my Dell laptop limit me to 2GB RAM?

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
