*.force RAM + Dimension 2400 problem - Please help!

[refined]

Hi there:

I am having trouble upgrading ram on my dad's Dell Dimension 2400 PC.

It's a 2.66ghz with 256mb ram PC2700 stock ram.

I tried sticking a 512mb *.skill DDR (http://www.newegg.com/Product/Product.asp?Item=N82E16820231026)
That's PC3200..

Everytime I boot up the computer with the new 512 chip next to the 256 one (I know it's in correctly .. am used to swapping ram) it beeps like 5 times and the computer won't do anything and I know it doesn't work.

WHat am I doing wrong? I tried upgrading the BIOS to the latest version on my dimension 2400 but still; same thing.

Please help!

Thanks!

Look in the motherboard manual -- check out the beep code you're getting, and what it means. Also check out the different memory configurations that are listed, and make sure you're using the right slots...

I had a dell with the exact same problem. the 512 (3200) and the 256 (2700) worked when they was in there by themselves though, but they would not work together. I sold the dell
