With what can I replace my RAM?

Hi everyone !

I’d like to boost my iMac 21,5”, 3.06GHZ, INTEL CORE i3 (>mid 2010) ; I already installed a new SSHD and I’d like to change the RAM. I have a few questions though :

The original RAM is 2GB DDR3 1333MHZ PC3-10600S SODIMM, serial number M471B 5673 FHO-CH9 SAMSUNG

1. Is it possible to upgrade the RAM and use 4GB DDR other than 1333 MHZ PC3-10600S ?

2. Is the serial number important ? Do I have to get the exact same ?

3. Do i have to use the SAMSUNG brand or any other brand like Crucial is compatible for my mac ?

4. Can i Replace CORE i3 by CORE i5 ? Is it compatible with the initial motherboard ?

Thanks everyone ! Thank you for the very useful tutorial !

As for your Q's heres a bit more:

#1 - I wouldn't say sensitive its more the fact the logic board is not tunable like an over-clocker board is so going with the ultra-fast RAM is just not possible. This is no different what a standard Compaq or Dell system would be limited to. Basically, the RAS & CAS is locked.

#2 - S/N of the RAM chips is unique per module and has no bearing.

#3 - Just make sure the RAM you get is claimed to be compatible with your system

#4 - You are limited to the chips Apple used Jumping to the i7 is what I recommend for either a i3 or i5 system otherwise it makes little sense to upgrade.

I would also go with a SSD if you want some zip!

• No Macs are sensitive to the speed. Even if you did upgrade to faster RAM, it wouldn't run faster. You can upgrade to 4gb or 8gb chips.

2. Is the serial number important ? Do I have to get the exact same ?

Serial numbers do not need to match.

3. Do i have to use the SAMSUNG brand or any other brand like Crucial is compatible for my mac ?

Brand doesn't matter, but I've seen issues with some Corsair chips. Crucial is a good brand.

4. Can i Replace CORE i3 by CORE i5 ? Is it compatible with the initial motherboard ?

@danj should answer the question. Simple answer is yes, you should be able to replace the i3 with the same generation i5 or i7, given that the CPU is not soldered on to the motherboard.
