Can I use 2GB + 8GB Ram with different frequency?
I wanted to upgrade my MAC Book (mid 2010 - 7.1) with 2x4 GB Ram chips from Kingston. I got the latest El Capitan running and even with just 2x2GB it's running actually very good.
I bought two Kingston KVR16LS11/4 - with 1600MHz. The dealer told me that it will work with any MACBook.
So I installed the two chips and nothing happened after I press the start button. ?!?!
I soon found out, that the frequency is the problem. (Stupid me). So I just entered one 2GB(1066MHz) + one 4GB(1600MHz). The system starts and gives me 6GB at 1066Mhz. I was working a little with the computer and everything seems to be fine. The startup take some more time - but this could be something else as well.
The problem is - I am in Peru and it's a friends computer. Here it's almost impossible to get chips with 1066MHz (tried Mercado Libre - like the Amazon of South America) 1333MHz is possible - but no 1066Mhz available.
Soooo - The question ist now if I could use 2GB(1066) + 8GB(1600) or 8GB(1333)
Because it will be much easier to exchange the two 4GB with one 8GB with our dealer - then finding two 4GB(1066)... The Apple homepage tells me that a MAcBook Pro 7.1 can handle up to 16GB.. Should work - shouldn't it?
The best would be to get one 8GB chip from OMC - unfortunately I didn't know about this before... I asked OMC already and they said that the 2GB(1066) + 8GB(1066) setup will run.
Ok - who has experience on this or even running a system with unequal DDR3 chips at different frequency.
I just wanted to tell you that I successfully installed a 8GB (1333Mhz) Ram in the MAC Book and it's running smooth and fast now. Yesterday I did some extensive testing with photo- and video editing software...
No Problems so far... LR5 runs as fast as on my MBRetina"2013"...
Is this a good question?
