Haven't you ever noticed that has tested higher configurations that what was technically specified by Apple? Depending on the type, the logic board and the memory modules available at the time may impose a limit less than what the CPU can address. If you notice, Intel states that it's determined by the "type of memory." This is where the logic board comes into play. For example, on an original i7-920 CPU, the maximum amount of memory that can be addressed is 24GB of RAM. There has even been conjecture on the "additional (physical) space" required for the new chips.įirst and foremost, the memory limit is primarily determined by the CPU. There has been a lot of speculation as to how much memory a computer can address. The key here is how accurately the rework station can deliver the heat necessary to flow the solder.īecause the heated air or infrared light is focused directly to the work piece, heat damage to the remainder of the board is mitigatedĪs for my personal experience, I have had GPU's replaced in Apple logic boards that weren't covered by Apple's GPU replacement program using this exact method and not only got a year's warranty on the work, but the logic boards lasted for years after. A quick search on Amazon yields both infrared and hot air rework stations that vary in price from $150 to $6,000 depending on the the bells and whistles you want. However, obtaining a BGA rework station is not out of the realm of possibility either. It doesn't need to go back to the factory as doing BGA rework doesn't damage the board.Īre you going to do this with a soldering iron/gun that you get from Radio Shack or your local electronics supply store? No. 1 You actually don't need a significant amount of "electronic engineering" skill to remove a chip and replace it with another. Replacing a chip is actually quite an easy process if you have a BGA rework station and a little bit of practice. No idea how much memory can be addressed.Basically, they all revolve around one of the following three themes:
Unfortunately, there is a lot of misinformation out there.
MACBOOK PRO RETINA MID 2015 MEMORY UPGRADE UPGRADE
There's a ton of responses out there whether you can/cannot re-solder memory chips to Apple logic boards in an attempt to upgrade RAM. The short answer is yes (anything is possible), but is it feasible?
