16gb in mid 2010 7.1 macbook pro

hi all.

I have a macbook white unibody mid 2010.
recently I bought the RAM from ebay germany.
this is the link:

http://www.ebay.de/itm/2x-8GB-16GB-DDR3-1066-Mhz-1067-Apple-MacBook-Pro-iMac-mac -mini-PC3-8500S-SO-DIMM-/351041951314?pt=DE_Technik_Computerzubeh%C3%B6r_Arbeits speicher&hash=item51bbbb1652
(It is the same as bought "gunnar-mobimation")
The brand is CSX.
2x8gb
I had understood that I had to install osx lion or higher system in order to accept the ram. for that reason, I installed mavericks.

but...

The mac never worked. Just heard a beep that comes and goes.
and I already tried:
- Install two RAM memory (2x8gb). nothing.
- Install only one ram (1x8gb). nothing.
- Insert a memory 8gb ram with another 1gb (Original apple ram). nothing.
also I try updating the EFI to the latest version. but nothing happened.
I leave you the specs of my mac.
Greetings and thanks!

Well, if you will look at my previous posts, I would not order RAM from an unknown source as Macs are extremely finicky about their RAM - here are the notes on the supported RAM:

Going over the recommended RAM amount (which is only 4 GB), I would only order it from a source which had actually tested the RAM - and the amount - in the same model, not some ebay seller.

Return the RAM and order it from a recommended source.

Just in case someone faces the same problem (generic brand 16gb not working on MacBook mid-2010), I used Rember to test each 8gb module separately together with a working 2gb and what happened is that one of the modules was defective, but the other one is working fine. So now I have 10GB working which apparently is more than enough.

Thank you very much gunnar for the ebay seller link and your testimony. I bought from this German seller then, and have just put the 16GB in my Macbook Pro 13" mid 2010, working perfectly. Am a very happy man. Now gonna test out StarCraft 2 performance 🙂

Hi Matias, from your specifications, I'd say that the problem is the SMC, the latest version is 1.62f7 (SMC 1.6) and you seem to have a previous one. You can update it via apple. Here's link (in French): Mises à jour ** programme interne de l’EFI et ** SMC sur les ordinateurs Mac à processeur Intel - Assistance Apple

Hi Mr Ng,

Thanks for the information.

I was thinking of buying the above - mentioned German seller's memory cards... But first, I want to make sure that it is the right one.

I have a Macbook Pro Mid 2010 with a 2.4 Ghz Processor.

Is yours the same model as mine, with similar processing speed at 2.4Ghz?

Best regards.

Hi mobimation,

Thanks for the information.

Was your Macbook Pro 13" Core Duo Mid 2010, fitted with a 2.4 Ghz processor or a 2.6 Ghz processor when you installed the 16GB...?

I want to be sure before I buy the 16GB from the recommended seller above.

Hope to hear from you soon 🙂

Thank you & best regards

Do they work regardless of the processor speed?
