The bottom line? The results of our testing did not support Apple's recommendation and rather make it very clear that in addition to the potential economic advantages, there are real performance advantages to having more memory - even if it means not having a pair. It is only the models with GMA950 which Apple recommends the pairs for and from that we'd infer the recommendation is related to impact on video performance.
Of note is that rather than having its own dedicated Video Memory, the GMA950 shares its 64MB VRAM allocation for the main system memory.Īll of Apple's current Core 2 Duo Models (same is true between Core Duo equipped Mac models) share the same processor bus and memory controller. The models Apple recommends paired memory for all have the Intel GMA950 integrated video chipset in common. In December of 2006, we did testing to establish why Apple had recommended Pairs for MacBook, Mac mini, and certain iMac models.
