Re: Upgade Dimension 2400 from 2.4g Celeron?

Check the CPU you bought. The 2400 will support 400 and 533 CPUs, but only Northwood (512K) and earlier.

If you bought a Prescott CPU (1M cache), that's why it doesn't work.

The 2.8/533/512K will work - the fastest one that will is the 3.06/533/512K. None of the P4s with over-512K caches will work.

Well,

I did a couple searches and found that the Dimension 2400 that ships with the lowly 2.4ghz Celeron is suppose to support up to 3Ghz P4 at 533 FSB and PC2700 RAM.

I ordered a P4/2.8ghz/533 and 512MB of PC2700 from my local supplier.

I removed the Dell Celron and 512MB and installed the new - when I turned on the power I get all LED's illuminated on the front and nothing for video/sounds - the Fan runs, the unit appears to have power, but nothing.

Suspecting that the new P4 CPU was bad, even though it was a New Retail CPU, I installed it in another computer (not a Dell Dimension, an ASUS motherboard) and it detected the CPU and RAM correctly.

So, I suspected that the DELL PSU was not powerful enough to run the new P4 CPU - replaced the Dell PSU with an ANTEC 480W PSU and tried the P4 again in the Dell - same thing, NADA, nothing, don't work. In order to validate the new Antec PSU I reinstalled the old Celeron and RAM and it worked fine. So, I tried the P4 and the old RAM, nada.....

I called Dell support in Panama and was told that the machine does indeed support P4/3ghz/533 and PC2700 RAM......

Anyone upgrade one of these with a faster CPU and get it working?
