OWC offers 6gb ram kit for 4 gig max rated 'puter?

[shedshrine]

Do these kits for a computer Apple has rated at 4 gigs ram max really access an additional 2 more gigs of ram with this configuration? Anybody tried these?
(This is a newbie question isn't it, I'll ask there, would delete here if could..)

“Apple factory specification maximum 4.0GB, OWC tested to support 6.0GB maximum RAM. “

ram kit 6 gig

Should work fine. The "maximum" RAM figures were probably correct for the largest parts you could buy when that model came out. And for maximum RAM performance, 4 GB probably is the maximum; on many chipsets, you get a speed benefit by having a matched pair.

Unfortunately, 8 GB is probably a bad idea on that machine, since AFAIK it currently isn't supported by the 64-bit kernel.

Thanks "dgatwood", I tried to find out more, this link seems to show it's 64 bit capable (64 bit architecture and EFI), and maximum etended usable ram is 6 GB..

but cannot boot in 64 bit mode..

"I have the iMac 7,1, 2.4GHz and this application - 32 or 64 bit Kernel Startup Mode Selector - as does the terminal command show that the EFI is 64bit capable.

Apple has not enabled 64 bit boot mode for this iMac.

So the mid 2007 iMacs get no 64bit boot love."
