Help! Macbook Pro Ram installed at Wrong Speed

[Ozes]

Hello Macbook pro masters... I need some help!

I have a late 2009 Macbook Pro. Its system requirement for ram is: DDR3 1066mhz

Today I went into a computer shop to buy some ram for my macbook pro to upgrade from 4gb to 8gb. He said that he would install some kingston ram 4b DDR3 1066mhz but would need to run a test on it to make sure it works... after 45 min the test failed and he then put in a pair of Trancend 4gb in. The 2nd test was over 1hour and a half long but it passed. First I was a little upset because i dont know anything about transcend ram. And then I saw the package for it was 1333mhz. I asked him about the speed and he said it wasnt a problem and my mac would downgrade the speed.

Is this ok for my mac?

If the RAM test passed, it should be fine.

In fact, it's quite nice of the shop to actually run a memory test after installing it (which is the right thing to do but not every shop does it).

Yes, that's perfectly fine for your Mac. The faster RAM will run at the bus speed of your Mac; 1066MHz.

Technically it is running at the right speed since your Mac is not capable of running at 1333MHz.

Your computer can run at the faster 1333MHz.

you're fine. you got a slightly more expensive ram for less since it more capable. your computer will just downgrade the speed to the right bus speed if needed.

Thanks so much!

Thanks so much! For all your help Now all i need to figure out is why I only get 1 1/2 hour battery life!!!

What is your current battery health?

On a 2009 MBP it's probably because your battery is just old.

What is your current battery health?

I get a message that says service your battery. But other times it says my battery health is normal. I still have warranty will this be covered?

Thanks

If the battery doesn't have a huge number of cycles, Apple might exchange it for free. It's worth a try.

Very unlikely. A 3 year old laptop still retaining 1.5 hours is pretty reasonable to me. How many cycles has it done?

For an old model, maybe (they were rated at just 300 cycles).

However, my 2.5 years old uMBP still does 6h at ~400 cycles.

For the 2009+ unibody MBPs, Apple claims: "The built-in battery in the new 13-, 15-, and 17-inch MacBook Pro is designed to retain up to 80% of its original capacity at up to 1000 full charge and discharge cycles.".
