How To Check Faulty Ram Slot
How to fix a faulty ram slot - posted in Internal Hardware: ok ive got this laptop, when i use a specific ram slot the screen dosnt work. Is there any way i could fix this problem? Pop off the bottom cover and inspect the bottom cover plastic captures on the mid-plane seen here: One or both maybe broken, if they are you'll need to find a replacement to prevent the bottom cover from crushing the RAM slot. You may also need to check the cover its self to make sure it's not dented or bowed inwards. Windows comes with its own memory diagnostic tool. Use the Search tool that came with your version of Windows (for instance, Start Search in Windows 7, or the Cortana field next to the Start. 1) Ok you get the ram and you try each stick in the apparent dead slot. The sticks are tested and known to be good. 2) If it still appears dead, boot the PC with a stick in the good slot and clear your CMOS, enter bios and 'load default Values' and reboot. Power down, remove the ram stick and try point 1) again. You can post with Memory in only slots 3 and 5. So try one stick in only one of those slots. Also Check for bent CPU pins, what this also does is reseat the CPU and remounts the heat sink in case you have a bad mount. To me though, sounds like a dead slot.
I have a late 2011 15' MacBook Pro that at the end of 2016 had the logic board replaced under the GPU replacement program. So the Logic board is 7 months old. The computer is in great condition, never dropped or misused. Randomly the machine wouldn't start and it was giving me the three beeps, signaling a RAM issue. I tried reseating, replacing, cleaning the sticks and the slots. Nothing. Then I used just one stick and it worked. The bottom slot (when the computer is laying on its lid) is faulty and is not allowing the machine to boot, it'll only boot with one stick installed in the slot closest to the back case. What can I do to make both work? Or is one 8Gb stick a good option, will it perform as if there were two 4Gb sticks (Im worried that if one slot has went bad that the other will too.)? I'm very upset that a virtually new logic board is having this issue and that apple refuses to work on it because it is 'too old'.
Replacing the logic board is a way to costly option, so not really an option.
Ive tried loosening the logic board screws, as some have said that that has helped the slot read the ram, nothing.
