Too much RAM for processor problem?

I am not entirely sure of the motherboard chipset or any other hardware for that matter, but recently for my teacher I installed a pc133 128mb stick of RAM in a computer with pc100 256mb already in it. It had a P3 450mhz cpu in it.
It started up fine and ran fine. It registered the correct 384 mb and everything was good.
I got the extra RAM from this network guy at school. He comes back later and tells me that "the processor cannot handle the extra RAM." I myself have never heard of anything like that in my life, so I am curious if there is such a problem. I think he just let me put it in too soon and turns out for some reason he might not be allowed to do so or something.

Really? I thought I hadn't posted it or something because it didn't show up on mycomputing.net messages. I know I was in a rush when I did it last time, so I just figured I didn't post it.
Wonder why it didn't show up.. Oh well sorry about extra post guys.

Hey firedragom,
Did you deliberately spell your name with an M or was that a typo?
There *may* be issues with how much of the RAM can be cached, but I highly doubt the limit is as low as 384MB. When the cache limit is exceeded, the system takes a definite performance hit so it's generally best to stay within that limit.

Nah I always spelt it with an m. That was my email a long time ago and has been my username on many sites.
Anyway, ill do a little research. Like I said it is a p3 450mhz, real old.
Thanks

P3s in the 450-1000MHz (katmai, coppermine) range will cache up to 4GB of RAM. P3s in the 1133-1400MHz (Tualatin) range will cache up to 64GB.
You're fine with 384MB. 440BX boards usually take up to 1GB of low density RAM. 815 boards take up to 512MB of high density RAM. VIA PIII boards will take up to 3GB of high density memory. I've got a P3 system with 2GB of PC2700 DDR.
