== beyond its alleged 4 GB limit. Have to find the the specific link describing why you can use all of 6 GB but not 8 (via doubling-up some 1s --> 2s.)
Unclear if Any '4' could be used on this model and, apparently OS X gets all wonky at 8 GB on my mid-08, but 6 no es una problema. Hmmm.. Why IS that?

At ~ $120 to do swap, but for 50% more memory ... am pondering. And maybe their note re trade-ins!? can ameliorate sticker-shock.
I too habitually keep n tabs open, so more time before s w a p happens would be a Good thing.
(Or ... I could clean up may act by actual sane bookmark organization. After all these years. Fat chance, that.)

Maybe, similarly you also can over-clock / memory- ize on your teensy Server?


* Ed: except: mine is 800 MHz !='667', as in this kit for an '07 model ... gotta find link elsewhere re conversion of my 'iMac8,1' and its exact ID (via the sticker on bottom of pedestal). Details.. matter.

So then, here's the source of the wonkiness comment, re my 2.66 GHz model:

{sigh} 4 x '4x' would be Sixteen, but irrelevant. Seems I'd need also a 2x chip via their recipe, disposing of 4 x '1's. Bummer.
Maybe your gadget is more extra-expandable (?)

Some of those replies show a difference in brands, apparently for identical spec chips -- where one person swapped his MB and MM boards and both worked.

Turns out that my iMac has 2 x 2 GB, also just 2 slots..
Will likely settle for the 6 for now anyway; by time that extra-50% goodness wears off, the next 4 GB + trade-in creds will be a bargain.
Paying a tad more at iFixit is OK because that's how they pay for their superb How-tos and they guarantee at least the 6 GB kit.
(If the problem on iMac is also firmware, mayhap that too will happen by the time I need it.)
Ditto for you if MM problem is firmware, etc.

Thanks for the sleuthing.

A.

as sole problem re. MBP; I note that one replier asked re iMac but the OWC thread didn't digress there.. maybe part of OWC's not giving hints before kits are in stock.
Thanks for link -- maybe Apple will throw an iMac firmware rev. too, in some next update (and not Tell anyone?)

By the time I think I need the extra 2 GB -- 8 GB will be norm and the 4s should be bargains.
