RAM Upgrade

1.35 or 1.5 v (preferably the former) and CL11 for DDR3 1600 MHz.

As Kappy said.

Have a look here (crucial) and here (owc) so you can decide what to install and where to buy it from.

good luck.

RAM upgrades for the mid-2012 MBP 2.6GHz: OWC shows RAM with CL=9 and Crucial shows it as CL=11. Which is correct?

CL=11, I believe. I'd go with Crucial anyway...

Both are correct. CL-11 are the ones you need but going with CL-9 from OWC would work too since OWC is a large MAC reseller - I would however, go with Clinton on this one since I too use Crucial. 2 nanosecond is not really noticeable.

thanks for the quick responses at this hour. I did more research on CL so for those stumbling onto this discussion in the future, according to Crucial's website, lower is faster:

"CL — CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL."

The 2 extra 'clock cycles' doesn't sound like much, but I'm using this MBP for video editing. I have projects that sometimes now take 4 hours to render, so I'm looking to squeeze as much as I can out of it so I'll probably go with the OWC with 18% less CAS Latency. Not sure what that translates to in actual time, but a less CAS Latent life sounds good to me.

Crucial is the more reputable brand (I use a Crucial SSD without problems). Both have a lifetime warranty - OWC offers advance replacement, not sure about Crucial. Crucial charges tax in CA so the total price is almost 20% higher than OWC.

No worries......

Use whatever works for you.....I use Crucial 16GB in one of my Macbook and Patriot Signature 16GB in my other Macbook with no issues. Patriot being CL 9.

Not sure how much it cost in your area for RAM but I just picked up my 16GB Patriot RAM for $100.

good luck.

Very interesting. Local Fry's has the Patriot sticks for $100. I'll have to see what Patriot's warranty is. Thanks!

Patriot has a lifetime warranty in their RAM.

Just checked out Fry's they have your RAM there for $100 - Patriot Signature Series.

Better get them before people find out about the low prices.

Corsair (which I have in my latest MBP) also has a pair of 2012 sticks at Amazon for $115. It's the Vengence series - good stuff.
