RAM upgrade not working

[Forred]

Hi Everyone,
I read how to upgrade my RAM, on forums and the Mac Help section on my MacBook Pro, and followed the instructions to the letter but still didn't work. When I turned the computer back on all I got was, "beep beep beep", pause, "beep beep beep." Now the old ram is back in, and I'm looking for clues as to what went wrong.
MacBook Pro:
13-inch, Mid 2009
Processor 2.26 GHz Intel Core 2 Duo
Memory 2 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 9400M 256MB
Software OS X 10.8.5 (12F2560)

Existing RAM:
1GB 1Rx8 PC3-8500S-07-10-B1
China M471B2873EH1-CF8 0917

New RAM:
4GB.DDR3.SODIMM.1600
Taiwan C0JKH PO 213499

I turned it off, removed the back, exchanged two old, for two new, closed it up, turned it back on and 3 beeps was all I got. I was sure to touch metal inside, the DVD drive, before touching anything else. I removed and replaced the new set a second time, same results. When I put the old pair back in it started right up.

Am I using the wrong RAM?
Any help would be great, you all rock.

Hello and welcome.

Three beeps is a RAM error.

Yes, it sounds to me like you may have purchased the incorrect RAM type. Your MBP requires RAM with the following spec: 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM. Officially, it supports two 4 GB sticks of RAM.

-What is the exact brand/spec of the RAM you bought?
-If you don't know the above for sure, can you tell us where you bought it and what their part number is?

Hi,



I agree with Cory, re incompatible /wrong RAM. I have just upgraded my white 2010 Macbooks Ram to 8 GB no issues. Although officially Apple only recommend 4 max.

Thanks Cory,
I tried my best to buy the correct RAM, following recommendations and not going over max amount, etc. Maybe you could help me buy the right one, if it's for sale.
Here is what I bought from Best Buy:
PNY - Performance 4GB 1.6GHz PC3-12800 DDR3 SoDIMM Laptop Memory - Green

If that is the wrong RAM, could someone lead me to the right one?

Yes, that is the wrong RAM.

I listed the correct RAM above: 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM.

Your MBP supports two 4 GB DIMMs for a total of 8 GB.

I don't believe Best Buy sells that any longer. You may have to get it online from a company like OWC.

I see. Ok I'll go get that kind of RAM. Fortunately this kind of hardware is not too expensive, just need to find the right one. Thank you very much Cory for helping out.
