Mismatched RAM in a G5

2010-02-20 Thread Eric Volker
I currently have a dual 1.8GHz G5 that I'm in the repurposing. In the
process, I removed 1GB (2x512) of DDR400 RAM leaving 1GB in place. I do have
2 extra 256MB sticks of RAM, but one is DDR 400 and the other DDR 333. If I
drop the mismatched pair in the G5, will it automatically downclock the
entire bus to 333, or will chaos ensue?

Thanks,

Eric

Minimum ram support for that system is DDR400. I have not tried this 
with a G5, but based on past experience, if you install that DDR333 
module in it, it will render the system either unusable or it will 
ignore both of the modules and boot up and show empty slots. Most often 
it wont even allow the system to boot or post thus rendering it unusable.
