high sierramacbook promemory
So I have a Mid-2010 MacBook and I tried to upgrade the RAM. I put in 2 4GB sticks and it started to beep. I took out one, and it still beeped. When I put in one of the original 1GB sticks and a 4GB stick, it worked. Any help on getting it to 8GB?
Edit: I figured out only one of the 4GB sticks work in the 1/4 configuration.
I have upgraded the RAM to 8GB for my MBP470. See the config below. No problem happened. Be noticed that, 470 only support 1066MHz DDR3 RAM. Do not use 1333MHz RAM. The 8GB RAM is from Sumsung.
Typically you want to install memory in pairs (i.e. two 8 GB "sticks" or 4 GB "sticks") to make use of something called the dual-channel memory interface. What that in essence means from your perspective is that the computer can use two memory modules at once, one in each "channel," if they are matched. That gives better performance than using one and then the other.
The way Mac OS X works, your computer will use all of the available RAM when it can to cache things that it might need later--even if you don't need them in RAM right at the moment. The price of RAM what it is today, I would try to order another module of the exact same type as your 8 GB.

You should search for info about your mac on Everymac.com. I searched there for your mac and assuming I did it right I found this brief comment.
Sounds like it depends on which system you are running. I suggest you go there and see what else you can find or go to OtherWorldComputing or here which reports they sell upgrade kits for your specific Mac.
