I'd like to upgrade the RAM on my Mac Pro and I was hoping someone could point me to a place I can order the correct cards.
I currently have four 2GB cards, photo attached. I'd like to jump this machine up to 8 GB cards if possible.
Processor 3.2 GHz Quad-Core Intel Xeon
Memory 8 GB 1066 MHz DDR3 ECC
Graphics ATI Radeon HD 5770 1024 MB
Software OS X 10.9.5 (13F34)
Mac Pro, OS X Mavericks (10.9.5), Graphics ATI Radeon HD 5770 1024 MB
Thank you, sorry if this is a silly question:
Since it's in a 3 pack, is it okay to get these 3 and then keep the fourth slot as 2GB? Or do all four slots have to be equal amount?
They are not necessary to buy or come in 3-pack, but after all DDR3 means something, and what does 2GB buy you? Not triple channel for one thing, and not much upside to it.
Try without. Use Activity Monitor.
Keep the 4x2GB as backup set.
DDR3 means something
It certainly does.It means a later design than DDR2 and earlier than DDR4 or DDR5. But it has nothing to do with triple channel.
You can replace DIMMs in these Macs (silver tower Mac Pro 2009 through 2012) by the each. The speed penalty for running two or four instead of the optimum three is quite small.
8GB DIMMs cost about what 2*4GB DIMMS cost, so don't buy smaller than 8GB DIMM. And don't buy larger unless you are willing to throw all others away -- larger than 8GB are Registered DIMMs and do not 'play nice with others'.
