Enligt den här tråden på MacRumors går det utmärkt att köra 6 eller 8 GB i en MacBook Pro om den är Santa Rosa (juni 2007) eller senare:
Okay, I'm going to clear up some of the questions for this since it appears there is SOOOO many threads being created about this.
YES 8GB WORKS IN THE MACBOOK PRO EVEN IF APPLE SAYS THEY DON'T OFFICIALLY SUPPORT IT.
You have 2 options above 4GB:
Nu är inte 4 GB-minnen så billiga, om jag inte tar fel (rätta mig i så fall) så skulle detta minne kunna fungera men det kostar därefter. Och nyttan av 8 GB är nog inte självklar för alla, om man inte kör många virtuella miljöer. Men det är lite kul att det verkar fungera iaf.
Det finns även en liten FAQ i tråden:
Will my MacBook Pro support 8GB?
- Only the Santa Rosa and Penryn (MacBook Pro 3,1 and 4,1) can support this much memory. The MacBook Pro 2,1 only supports upto 3.25GB ram accessible so adding in 8GB wouldn't matter since you can only access >4GB. Currently, OSX Leopard (10.5.x) seems to have trouble accessing above 4GB of ram. It is unclear if this will effect users attempting to use 6/8GB in their MacBook Pro.
How do I know when my MacBook Pro was purchased?
- Read this: MacBook Pro - Mac Guides
If you fall into Rev D or Rev E specs, you can support 8GB.
If I add 1x4GB and 1x2GB, totaling 6GB; or just using 1x4GB; do I lose dual channel?
- Yes, you do lose dual channel.
Is losing Dual Channel a huge performance hit?
- Not really. It all depends on what you use it for. If you're doing a lot of modeling/rendering, dual channel might be a great help. For an average user or someone who runs memory hungry apps such as Virtual Machines, it is not much of an hit.
Isn't Leopard (10.5.x) 32-bit?
- Yes and No. Leopard uses both 32 and 64-bit framework. It is not entirely just 32-bit therefore it can access and use all the 4+GB ram. Unlike Windows XP (for example) it is completely 32-bit and cannot read/write/access anything above 4GB. If you don't believe me, its on Leopard's page on apple.com.
- Currently, there is some problems with OSX Leopard (10.5.x) to allocate more then 4GB ram without going into swap. Initial tests shows OSX Snow Leopard (10.6) to not have this problem. Further testing is being done in Page 4 of this thread.
Will 6/8GB be supported on systems other then MacBook Pro and Mac Pro?
- In theory, the Santa Rosa and Penryn MacBook and current versions of the iMac should be able to use the 6/8GB extra ram. However, until we have a guinea pig to test it, it is just a theory. If anyone does test it, please tell me and I can update this FAQ.
