I'm not sure I understand your post? Are you saying the top memory slot is not holding the module correctly and it's becoming dislodged? If that's what you mean, I have to ask.... are you using the correct modules?

According to Mactracker your machine takes:

Maximum Memory 8.0 GB
Memory Slots 2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM


If the slot itself is defective that would mean a logic board change. As far as using one module of 8GB instead of two modules of 4GB, yes it's possible but more expensive and probably will slow down memory access.

If you have a problem with the ram in one slot coming loose. Is the ram damaged or is the slot damaged?

If the ram is damaged...I would replace the ram. If it's the slot that's damaged...I would try to use some sort of tape (to keep the ram from getting loose)...and see if that is a long term solution.

Your understanding. I want to eliminate the use of the top slot and just use 1 (8gb) stick in the unit. (ive also uploaded a pic of the error)

Just so we are 100% clear...what are you currently doing when you get this message:

- What ram stick are you inserting?
- How many sticks of ram (1 or 2)?
- Which slot/slots (the good one or the bad one)?

I was going to post this answer earlier...but I wanted to wait and see how things turned out.

Max. ram for your MacBook Pro is 8gig. This means a max. ram/ram slot of 4gig (4gig + 4gig = 8gig). If each ram slot could handle 8gig sticks of ram...then your MacBook Pro's max. ram would be 16 gig (which it isn't).

So my answer to your earlier "max ram/ram slot" question would be 4gig.

Thus...if you're having an issue with one of your ram slots...with only one good ram slot available...then max. ram for this computer (with 1 bad ram slot)...will be 4gig.

I have to go with pigoo3 on that one. The most your machine will be able to handle is 4gb per slot.

It's also worth noting the the spec for your machine is DDR3 1066 (PC3-8500), you are using a 1600 module. In some machines you can get away with using the faster parts and in some machines it creates issues. I'd recommend going with the 1066 parts.

OK, now that I understand what's happening...... Nick is correct. You would only be able to use 4 GB not 8 GB. Also, take note of the type of memory I posted in my first reply to you. You're using incorrect memory which may be the reason for the KP. Buy your memory from either Crucial or OWC.

I was thinking the same thing. Incorrect ram density & incorrect ram type.

Back again guys,
So ive been experiencing the 3 beep issues for over a year. but just recently upgraded to the Crucial 8Gb memory at the recommended type for my 2010 MBP. I originally just thought i had a bunch of bad MEM (orig memory & Kingston Hyper X <!~ outta spec memory) that was causing the issue. I can accept the memory issues from the Kingston but here is my question....but got the 3 beeps , but the computer restarted normally and i was able to use it.. (normally would have to reseat the mem sticks)

WHY AM I STILL GETTING THE RANDOM 3 BEEPS ... Looking for other possible causes to this. RAM - changed... HD - changed New OS - installed.

Im aware that this is a memory data integrity issue but can this be caused by software. I use the MBP to dj using serato & this issue is driving me nuts.
