Dual/Multiple CPU’s

As you probably already know (or are about to) Windows 2000 supports multiple processors. What affect does this have on the Page File? Quite a lot actually - Multiple CPU’s means multiple (more) L1 & L2 cache. L1/2 cache is significantly faster than RAM & the Page File is, as a result having more of this will mean less Page File usage.

If you upgrade your current system to one that has multiple CPU’s then you’ll need to take the following procedure as you’ll need to update the HAL (Hardware Abstraction Layer) to be able to support these extra CPU(s).

Before doing so check whether or not your manufacturer offers a specific HAL update for this purpose. NOTE – Some of the following information can be read in this MSKB article.

1.       Right click on My Computer, select Properties.

2.       Click the Hardware tab, then click the Device Manager button.

3.       Open Computer & then double click on the computer type that is listed there, e.g. on my system that would be Advanced Configuration and Power Interface (ACPI) PC.

4.       Select the Driver tab, then the Update Driver button. Finally, click the Next button.

5.       Select Display a list of known drivers for this device, then select the Show all hardware of this device class button.

6.       Select the Manufacturer & Model as appropriate (one that matches your current type, except for multiple CPUs), click Next, and then click Finish.
