Question: MacBook Pro Mid-2012 Faultly Unexplained RAM Problem?

So I have had this MacBook Pro mid-2012 since 2014. I have been through the thick and thin with it because its been such a pain in the (you know what) for me.


My problem is whenever I turn my MacBook Pro on it will after 5 minutes freeze/show lines on the screen which are usually blueish. It will then proceed to beep 3 times simultaniously with a 5 second break. And I have to force turn it off with the power button. How do I fix this?


I have had AppleCare say to me its a problem with the RAM in the Graphics Card (is there really RAM in the graphics card?). But, on top of that theres this thread and other threads on the Apple Support website saying its just the usual RAM and something to do with a faulty Logic Board.


I don’t really want to have to pay for Apple to service this for me when theres so many people with the same model MacBook as me experiencing the same problem. Its got 18 pages of comments!


The thread I’ve been surfing through: - https://discussions.apple.com/thread/6481657?start=50&tstart=0


Please help me fix this! I am a BA (Hons) Uni student trying to study a degree amd I need my computer ASAP!

Answer:
Answer:

If you buy from a Mac-centric Vendor, they will tell you you could use more than what Apple originally recommended (up to two 8GB modules). Use a Vendor who says:


"It works in YOUR Mac,

or your money BACK."

The three beeps normally means a fault in the Ram.

There is the general Ram, there is Ram (512MB) in the Graphics controller on your main board shared with the general Ram, and there is a separate Graphics controller, not on the main board, with Ram (in your mac 1GB).

Changing the main board is very costly. Changing the separate GPU (NVidia in your case) is less but still considerable costly. Changing the main Ram is easy, and cheap, you can do that yourself:

For the main Ram go to macsales.co or crucial.com and use their offers, when giving the specs of your mac; the Ram specs should be exactly what is prescribed for your mac (204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM). Buy two chips of 4 or 8GB and replace them. You can see how on the two websites I gave .

There is an app that can check your main ram: Rember (http://www.kelleycomputing.net/rember/). It is very slow. Try that.

The graphics subsystem on that Mac is described as:

"integrated" Intel HD Graphics 4000 graphics processor that shares system memory

from:

https://everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-i5-2.5-13- mid-2012-unibody-usb3-specs.html

So the only graphics chip is built into the CPU chip, and it uses main RAM memory for the display buffer. With this sort of architecture, problems in main RAM memory can show themselves as wonky patterns on the screen (which is just what you are showing).


Debugging could involve running the Hardware diagnostics, and/or substituting known good RAM memory modules.


Because MacOS ElCapitan and above run much better with MORE than 4GB of RAM you have now, you should consider adding more RAM memory. The "three beeps" symptom may be an indication that one or both of your current memory DIMM modules (the little cards with multiple chips on them) may be faulty.

Unless you are majoring in counseling, it does not make sense to look through 18 pages of a thread that does not have a clear solution already posted. You may not have the same problem as all the others.

If you read the most of the thread correctly. You would find most of the pages don’t have official solutions. But ones that they have found through their own research & testing.

And moving on to the actual point. My computers a MacBook Pro (mid-2012), 2.5 GHz, 4 GB RAM, 500GB HDD, intel core i5.


I wiped the Macintosh HD drive and after about 1 week of using it after that It started having this problem.

You have posted the specs for the 15-in model with dual graphics. I think S4MMZ has a 13-in model, which is very different inside.

Hi Grant, thanks for the information! I am currently running my macbook now using just 2 GB of RAM because I took the other 2 GB out as of 20 minutes ago. This is because on that thread I was talking about I posted a link on in the main question I asked. One of the people said taking out the closest RAM chip to the keybord will help it not crash. Though I’m still not certain at all that it will not crash again.


I have just done an EtreCheck and I’ll send it to this thread now.


How do I do an Hardware Debug (or whatever you called it)? Will that possibly fix my RAM?


Thanks for your help :) my MacBook Pro says it’s upgradeable to 8 GB (max) does that mean I can still upgrade more into the RAM module itself? Like to 16 GB?

Yes, correct, the 13" does not have the discrete graphics. How did you find out that it is the 13" model?

We both agree that new (and more) Ram may solve the issue, without much cost. Imho replacing the main board is too expensive to do.

2GB of Ram is by far not enough, follow our advice and upgrade the Ram to 8GB at least, replace both 2GB chips with 2 4GB chips, of the exact specification.

Tunnelbear is superfluous, if you must have more privacy, use another VPN.

Wondershare is not "wonder", sloppy programmed and often causing issues, uninstall it completely, as it is doing nothing for you.

You have already demonstrated you do not need a "matched pair" by running with one module. My experience with most MacBook Pro of that era is that they will accept two modules of different sizes. If money is tight, you could add one module of a larger size (I am running an 8GB and a 2GB in a similar MacBook Pro).


There is a very slight increase in speed with two matched modules, but the speedup in imperceptible in real-world use.

Ok, for now I'll just use my MacBook with one slot of 2 GB RAM. But for the future (just a few days) I will upgrade to two 4 GB chips which is what my MacBook can only take 8GB (max RAM). Thank you for all your help guys and if anything else goes wrong with my RAM when I upgrade I'll keep you posted on here.
