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?
When it does, try putting the RAM stick you took out in place of another RAM stick (leaving its original slot empty). If the PC malfunctions again, then you know it’s the RAM stick that’s the problem. If the PC works fine, then you know it’s the RAM slot and your Mobo’s faulty. Faulty Video ports (HDMI, VGI, DVI, etc.). Second RAM slot is not working! I try put there 2 different DDR3 (original Samsung and Kingston). Both of them working fine in the first slot. But not working in the second one. Not working separate in second one, and not working together with the first slot. First slot separate working fin.
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.
Has anyone else encountered this issue? What did you do. What do you recommend?
Thanks.
How To Check Faulty Ram Slots
Is this a good question?
How To Check Faulty Ram Slot Speed
I've got an Asus P5B Deluxe motherboard. Today I tried adding some new RAM to take it from 4GB to 8GB. The board is about 6 years' old. I've never used the black RAM slots before, only the yellow ones (2x2GB in slots 1 and 3).
My system only sees 6GB, not 8GB. I've tried various combinations of the RAM, get the same result.
To check the new RAM wasn't defective, I tried it in slot 1, a known good slot. All 4 sticks of RAM worked in slot 1, so the RAM wasn't faulty.
All 4 sticks work in every slot except slot 2 (the first black RAM slot). If I put any stick in slot 2 - old or new - the PC is dead, it won't even boot to the BIOS.
So it looks like I have a defective RAM slot.
Does anyone know of any way to fix this? The board is too old to RMA. I've tried an emery board down the defective slot, and I've tried squirting WD40 down it. No improvement.
Does anyone have any other ideas on how to get that bad slot working?
Thanks!
