SDRAM not recognizing properly

[Mocker]

I've just installed an additional dimm of PC133 SDRAM in my friends computer. It had 128 and I added 256, but the 256 is being recognized as 128 (both in the BIOS and by CPU-Z).
Does this mean the system isn't using the full 384 or is it just not being recognized.
I researched the ram type thoroughly so I don't think compatability is the problem.
Any ideas?

I don't have complete specs on hand but...

HP Pavilion 512n
Celeron 1.4
810 chipset
ASUS ?ATUW?
164 pin PC133 SDRAM

Thanks!

try reseating both sticks of ram. Try with only the 256 stick. Try switching around with the slots.

I installed one 256 in my friend computer too. He had 192 and now he only have 330. It's pretty weird. The 256 says it is a 128. I think these system can't support PC133 or 256.

i had a p3-450 system that could support up to 768mb (in 3*256) sticks.

My friend computer SAYS that he can support it.... but he can't.
