difference in ballistix for pc and mac???

I was wondering if there is any difference in pc4000 ballistix memory for a mac g5 and the standard for a pc? all specs seem same, crucial says they are the same but i just wanted some reassurance before buying.
link for the g5 mac memory part # CT413224

link for pc4000 pc mem part # BL12864Z503

any help is appreciated.

They are the same, we have verified and tested them in the G5 and know they work fine. That is the reason for the different part number. CT413224 is an external part number that is designated for a tested system so you will know the memory is compatible with your computer.

I hope this helps.

thanks for the reply I just got some for a steal.
