P5GPL: memory upgrade problem

Hello everyone
I have a PC with ASUS P5GPL motherboard and 2x256MB Kingston DDR RAM. Today I've bought 2x512MB Kingston DDR, because I wanted to have 1,5GB of memory. Unfortunately, my BIOS detects only 1024MB, and every time I boot I get a message: "Due to chipset limitation, this motherboard can only support maximum 2GB and 4 ranks memory.". But why? AFAIK 1,5GB<2GB ;-) I'm sure that my new RAM works fine, I've already tried to boot without my old 2x256.
I did a thing called "Crucial system scan", and, surprisingly, it detected whole memory properly:
256 MB
DDR PC3200
512 MB
DDR PC3200
256 MB
DDR PC3200
512 MB
DDR PC3200
But bios, windows and cachemanXP say that I have only 1024MB :-(
I've already upgraded my bios, it didn't change anything.
I'm totally confused... Does anybody have any idea what should I do?
Thanks in advance for any help.

Hey I have the exact same model motherboard, I have had my ram at 1GB and I decided to max it out at 2GB with 4 x 512MB sticks at all four slots, well the stupid board gives me the same message. I also did the crucial scan and it also detected all sticks properly. I don’t know at least my two extra 512 sticks were free. But I’m glad I am not the only one with this problem.
