The only thing that's special about the bottom slot is the plastic is black. You're going to have a harder time finding the correct part but it's not impossible. In terms of sourcing the part, this machine uses a uncommon socket style.
It's best to remove this and put it on wax paper to preserve it.

You will also lose the serial number sticker on the board if the top slot is bad if is is not transferred or it is burned, so try to keep it intact if possible. You also won't be able to find sockets that use the Apple OEM color, since Apple doesn't like 3rd parties being able to repair their stuff. The difficulty of sourcing the part and doing the repair depends on which socket is bad but the top slot is much harder to replace then the bottom slot. If you have tested both of these components and find notheing wrong, it's a memory socket problem. It most likely will not be and you'll be better off using the machine with one RAM slot for the rest of it's life or selling it for parts. However, if it is a bad northbridge, then you will need to decide if it is worthwhile to have the chipset replaced. In most cases, the problem lies with the RAM instead of the socket or chipsets. If this works, both memory modules likely have a problem and replacing the memory was enough to clear up the problem. The downside to this is you can run half of the memory you could before, but it's the easy fix to deal with a bad RAM slot.īefore you replace the RAM socket, check if the northbridge has an issue and use a completely different set of memory. The average person is better off running a single large memory module, since the repairs that are required to fix the board are very difficult. Unfortunately if you want to have both RAM slots available, you will need to have this repair done and you don't want to replace the motherboard. While it is beyond the skill level of most people, the RAM slots can be replaced. No matter where you push on the back plate at this point, the ram carriage as well as the wedges used to keep the ram in place will be protected from any kind of pressure. With out disturbing their arrangement, place the back cover on, put screws back in place, turn on. They do need to be thick enough to be held in place when you put the back cover on. Don't lay them on any component/capacitors, You'll have room. Lay one spacer right on the logic board parallel to the rear side of the ram carriage, and the other on the board perpendicular to the first. Next, get two pieces of spacer (I used a thin gauged bamboo knitting needle cut into two pieces no longer than the width of outside edges of the ram slot carriage.) Your spacers need to be non conductive, they need to be thicker than the rim of the ram carriage from board to top of carriage, but not so thick that they cause your back panel to warp. Wedge both sticks of ram in their slots with a shim in-between the ram and the battery housing.
