Hi all !

A few days ago, I replace the original 240 MHz 603e PPC processor with a 300
Mhz one.
And it's working fine on 330 Mhz frequency. ( but works at 350 MHz maximum
frequency)

Speed results:

603e

240Mhz(old) 300Mhz(new) 330Mhz(overclk.) 350Mhz(overclk.) 366Mhz(unstable)
--------------------------------------------------------------------------
295Mips     368Mips     406Mips          430Mips          450Mips  
182MFLoops  227MFLoops  251MFLoops       266MFLoops       278MFLoops



Can anybody help me in increasing the PPC RAM access speed ?

Unfortunately I didn't use more than 60Mhz bus clock frequency with the
G-Rex board. Before G-Rex, my PPC+Bvision worked fluently at 66.6667 Mhz
bus clock frequency.
