Ditto on this, its just a cosmetic Open Firmware glitch, PCIe G5s do the same thing interestingly enough
also worth noting the DDR2 on the DLSD, was nothing but a marketing thing
it runs at 333Mhz regardless of what you put in the slots (well just whatever double the FSB is at) and has no speed advantage over regular DDR in this case, especially given the very slow by 2005 FSB of the PowerPC G4 CPU
I was wondering why my (downclocked) PC2-5300 RAM was running at 333MHz as opposed to 400...
