For the most part it should be easy for a memory assembler to use PC2-6400 parts and just encode the serial presence detect EEPROM as PC2-5300. However - PC2-5300 is being phased out and there's a good chance that they simply label it as such to avoid having to produce inventory that's been phased out. Kingston ValueRAM seems to be notorious for it. I didn't think that Crucial would do that.
What WILL NOT work is putting a single 8gb RAM chip into one slot. By itself, it doesn't know what to do with PC2-6400. Your Mid 2009 Macbook Pro can run PC3-8500, PC3-10600, PC3-12800 (1066mhz, 1333mhz, 1600mhz) literally anything above 8500 in the PC3 format will work.Higher speed RAM clocks down, or reduces speed to match your computer capability. Once a true PC2-5300 module is used in the pair, the memory controller knows to default both modules in the system to the slower setting.
The last thing that I did with it was update it to Mountain Lion, which turned out to be somewhat of a mistake because it is now painfully slow (which is why I havent touched it in a while). I pasted the hardware a software specs below. Sounds like a classic case where a PC2-6400 (DDR2 800) module was labeled as PC2-5300 (DDR2 667) - and then is used with one of the Intel chipsets (the NVIDIA chipsets don't have this problem and reportedly will run PC2-6400 at full speed). Im trying to revive my old college laptop which is a white macbook from early 2009.

Upgrade bundle includes all the parts and tools needed to mod your iMac. If that helps here is the information from the System profiler: Max your iMac Intel 20' EMC 2266 (Early 2009) with 8 GB RAM. Crucial also recommended me to check directly with Apple on the matter. I sent an email to Crucial and they suggested that I ensure I have the latest firmware as it seems to be a limitation/restrictions on the motherboard. I just don't understand why it would work only while inserting one of the original modules?ĭuring the purchase, I made sure that I selected the correct memory modules using Crucial tool and I also checked that I got the correct speed (PC2-5300 667MHz). As such, the Macbook works properly and recognise 3gb.Ĭlearly, the memory modules are not faulty. The only way to make it work is by inserting 1x2gb and 1x1gb (original module) in any of the slots. Upgrade bundle includes all the parts and tools needed to mod your laptop. 128GB SanDisk Ultra SSD, I had 10.6.8 and 10.10 on there, but eventually settled with Yosemite since my cousin likes the new look and features despite lack of TRIM support.

If I install only one of the 2gb module in any of the slots it doesn't work either. Max your MacBook Pro 15' Unibody Late 2008 and Early 2009 with 8 GB RAM. Like others have reported, when I install the 2x2gb the computer can turn on but do not boot up and get stuck on a black screen. I recently purchased two 2GB memory modules from Crucial. I'm experiencing similar issues as others trying to upgrade my MacBook to 4gb RAM.
