Hi all,

I didn't really know where to put this.... So I figured here.
I am going to upgrade from 4 gigs to 8 gigs of ram, it's only like $45 and I figured is would make this thing even better(not that it needs it). My question is...when I go to crucial there are two packages and the only difference is 1.35V and 1.50V. Can anyone tell me what the difference is? I looked on my "about this Mac" system preferences. I didn't see anything about this.

Thanks in advance...
Flu

Your post was moved here to "Apple Notebooks" since you own a MBP. It did not belong in "Schweb's Lounge".

More details needed there are some twelve or so 15" MBP from Core Duo to i7. Check out OWC for correct model and memory details.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Sorry, I really just wanted to know what the difference between the 1.35V and 1.50V was.

Well i just upgraded my RAM from crucial and wondering the same thing. I went with 1.35v. As far as i know it's just how much power it will consume.

I'm sure someone with knowledge on this will chime in.

Just for the record the 1.35v works great with my 15" MBP (late 2011) 2.2

Your MBP user manual should provide that information, however this is the memory you need:-


Upgrade Memory for Apple MacBook Pro to 8GB, 12GB, or 16GB DDR3 1333MHz SDRAM + SSD and Drive options up to 1.0TB - for all 13

Can'y help with the voltage difference.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

DDR3 spec voltage is 1.5v, now there is other standards.
Two low voltage DDR3 standards have been introduced by JEDEC. The DDR3L standard operates with a default voltage of 1.35V, using at least 15% less power than standard voltage (1.5V) DDR3. Modules with DDR3L are labeled ’’PC3L’’, and examples include DDR3L‐800, DDR3L‐1066, DDR3L‐1333, and DDR3L‐1600.

Any performance difference between 1.35 and 1.5 that you know of?

Lower voltage will not alter the performance level given the same specs to 1.5v eg, your cas, tcas ratings etc.
There may be some miniscule battery gains as it's not requiring as much juice to power the modules etc.
Lower volts also means less heat, though how much by I can't tell you.

Lower voltage usually comes from improvements in the product itself, be it the silicon, circuitry, manufacturing process and what have you.

Go the Mac!!
