run the D-A-L hardware scan to find your mobo model #.

the dell has Intel boards. so once you have the #, search Intel for the board specs.

D-A-L Hardware Scan

Intel Motherboards

i found this:

Motherboard:
Property Value
Manufacturer Dell Computer Corp.
Model
Name Base Board
Part Number
Product 0G1548
Serial Number ..CN7082138NA0O0.
Version A00

when i searched for CN7082138NA0O0, it did not find anything

i have also been on the dell website-Nothing didnt find any processor upgrades i am prety sure you cant upgrade the processor on my pc
If only they did external processors lol :-p

is it possible to just upgrade the Cache rather than the processor?

Here's a link to a technical spec sheet for the Dell Dimension 2400:

http://support.ap.dell.com/docs/syst...m_en/specs.htm

It says that it can run the following processors:

400MHz FSB:
Intel® Pentium® 4 2.2 or 2.4 GHz
Intel Celeron® 2.0, 2.2, 2.3, 2.4, 2.5, 2.6, or 2.7 GHz

533MHz FSB:
Intel® Pentium® 4 2.266, 2.4, 2.53, 2.66, 2.8, or 3.06 GHz

I can't warrant that this information is definitely accurate for your specific system but it seems pretty likely

thanks verry much DJNafey
