Reviewed: 32Gb of Kingston FBDIMMS (8x4Gb FBDIMM) in 2008 Mac Pro

2008-09-25T19:11:00.036+01:00

Here we review a FULLY stocked 2008 Mac Pro 8-core 2.8Ghz machine. Kingston Europe kindly donated 32Gb of part No: "KTAMP800K2/8G" Mac Pro FBDIMMs (8x4Gb) for the review; come back soon to find out how they scored, along with photos and GeekBench results. We are going to test the kit in the following configurations (in pairs of 2x4Gb modules at a time):

2x1Gb = 2Gb (Apple stock configuration)

2x4Gb = 8Gb

4x4Gb = 16Gb

6x4Gb = 24Gb

8x4Gb = 32Gb (Maximum configuration!)

Here we can see the idle temperatures of the FBDIMMs. The fan speed barely changed at all when upgrading from the stock 2x1Gb FBDIMMs, to a fully loaded 32Gb 8x4Gb Mac Pro:

Upper riser on the left, lower riser on the right:

Default 2Gb factory configuration: 2x1Gb FBDIMMs - one upper, one lower

8Gb Kingston: 2x4Gb FBDIMMs - one upper, one lower

16Gb Kingston: 4x4Gb FBDIMMs - two upper, two lower

24Gb Kingston: 6x4Gb FBDIMMs - four upper, two lower

32Gb Kingston: 8x4Gb FBDIMMs - *Maximum config* - four upper, four lower

GeekBench Scores (64 Bit)

2x1Gb factory config:
