If the bios does not see all this extra memory I don't think the OS will have much luck either.
If there is no memory limiters on the mobo or in the bios I think I might visit the makers site and look for some info, like a bios update maybe.
Hi, I just installed a new 1gb 266mhz DDR memory stick to the 2nd DIMM slot in my computer meeting all the specifications. But for some strange reason the original memory, 512mb 266mhz DDR, is no longer recognized by Windows or BIOS. I tried switching the two sticks but it had no effect. My computer manual states several times that it can be expanded up to *2 gb of 266mhz DDR. I then read somewhere that the BOOT.INI might have a set maximum memory, but in msconfig it was unchecked, however when I checked it, I couldn't raise it above 1024mb, but it is certain that this motherboard can be expanded up to 2gb. It seems that both sticks are compatable. I'm at a loss and I'd appreciate any help.
