adding memory

["Gene L Reynolds/GYR/CC01/INEEL/US" <GYR inel gov>]

Hi all, I have an Intell p3/500 Running Rh6.1. I had 2 256mg double sided
ram chips. I installed a 128 single sided chipset , both the same speed. I
tried to boot and got an error something about kernel hash table wrong when
booting.  The box checked out the MEM ok.  Do I have to build a new kernel
to add new memory............. thanks all
