MacBook (white) PC6400 as PC5300?

[Vir]

Hi,

We've just bought a MacBook 13" 2.13Ghz with 4GB PC6400 ram, the guy at the apple store build it in, when we came home I turned it on only to find the About this mac screen showing 4GB PC5300 (667Mhz) and 1066Mhz FSB. We went back to the store to confront them with it, they had no idea why it was this way.

Is this normal or should we return it, reinstall osx or change some setting?

Thanks in advance...

Well no, but I know 667Mhz is PC5300. It says 667Mhz at the About this mac screen. At the About this mac screen you can open a link to a sort of computer information tool. In that tool it says the memory, both slots are 667Mhz.

The guy at the apple store showed me that there were PC6400 (800Mhz) dimm's in there. But they have no clue why it shows 667Mhz in OSx. Also I found that the bus speed is 1,07Ghz, which tells me it's at 1066Mhz

I'm gonna do a bit of searching myself in a minute, but my experience with PC's tells me this is NOT correct.

I asked the guys over at the store if no one else had reported this in, and they said "Nah, most Apple buyers have no clue what is inside the mac, they just buy it because it is apple"... I was like ... "ehm... ok...."


EDIT:
I've just looked it up, the FSB should be 1066Mhz, it says this on the site:

# 1066MHz frontside bus
# 2GB (two 1GB SO-DIMMs) of 800MHz DDR2 SDRAM; two SO-DIMM slots support up to 4GB

Can it be that it supports 2GB 2x1GB of 800Mhz but when using 4GB it can't support 800Mhz but falls back to 667Mhz or something ? :S


EDIT2:

I've just found out on the Apple forums that the white macbook does NOT support 800Mhz RAM. So basically it's for marketing reasons. I'm kinda ****ed off about it but hey, the macbook runs fine so...
