Hi, what is the voltage of the RAM voltage 1.35 or 1.5v? I have a late 2011 Macbook Pro 15" and was told to only use RAM with 1.35v. Correct? Thanks

I don't really have your answer, although the Apple web-site should. Remember, sometimes manufacturers change parts specifications depending on the exact model# and serial# within a specific model#. There are RAM buying websites that offer more detailed info. about which RAM for a specific Model & Serial # & year of manufacture. Some have really good guides. Some have actual human beings to answer this type of question. Sorry I could not be of more help.

only will work with 1.35V volts http://www.amazon.com/Kingston-Technology-16-PC3-12800-KHX16LS9P1K2/dp/B009W0ZFUY/ref=sr_1_5?s=electronics&ie=UTF8&qid=1392017209&sr=1-5&keywords=1.35v+16gb+ddr3 http://www.amazon.com/Crucial-Ballistix-PC3-14900-204-Pin-BLS2K8G3N18AES4/dp/B00DSGLMSM/ref=sr_1_10?s=electronics&ie=UTF8&qid=1392017209&sr=1-10&keywords=1.35v+16gb+ddr3

I'm no expert, but I did work on computers for about a decade. Bus voltages are pretty important and I would think the bus voltage of 1.6v would not be enough to drive the 1.8v RAM. The difference in voltage to could lead to unpredictable results which in computer speak means things might be really screwed up, and intermittently so that you might never trace computer problems to a difference in RAM bus voltage. If at all possible, my recommendation would be to stick to the 1.6v. Once you open RAM it's not returnable so buying and trying in not an option - at least not for me. Sorry if this doesn't help.

Thanks for your question! This RAM is fully compatible with that MacBook Pro model, and will upgrade it to 8 GB. Thanks!

Hi Jason,The DRAM Voltage can be adjusted in the BIOS of your system. The default specification of the memory is 1.5V and the XMP 1600 profile runs at 1.65V. So it should be able to run at 1.65V without an issue. Although, there is no guarantee that it will work properly with other RAM.Thank you for using HyperX memory.-Jewel @ HyperX Technical Support

Worked on MacBook Pro 17" 2013.... Does your book use DDR 3 1600 MHz 1.3-1.35 volts? If so then should be fine

I wouldn't recommend it. This is CL10 memory and at 1.5v. Ideally I think the mac mini wants 1.35v at CL11. I've actually tried CL9 before and the mac mini was not happy. CL10 is cutting it close.

Thank you for your interest with our product. Even though Original battery is rated at 7.2V because each cells contain 3.6V. With New technology nowadays each cells can make with 3.6V/3.7V for Macbook Pro aftermarket battery. Therefore, 7.2V and 7.4V will not produce any damage to your laptop at all. Your satisfaction is extremely important to us. It is how we measure the success of our firm. If you have any questions please feel free to contact us at (626)698-8163. Thank you for your support and it's our pleasure to assist you.

By default, these sticks run at 1.65volts. I know some AM3 boards have issues running quad channel ram at this voltage rating. I would personally look to see if you could find sticks in the 1.5 volts if you were going quad channel. 2x8gbs would work regardless of voltage

I only can tell you , that this is working in a 13-inch MacBook Pro Mid 2012.I replaced my two 2GB Ram's against 1 8GB Kingston Module. It is working perfect.

Hello Changhwan. I wish I could help you, but I used this Ram for a PC/laptop not for a Mac. It was a great addition though. I run graphic software, so it really helped boost performance going from 6 to 8GB. Hope this helps in anyway.

Hi M Long,COuld I ask exacetly what you did to upgrade your ram yourself? I know that if we do upgrades ourself and break or damage anything, that could cause the warrenty for the lap top to be void by apple, so I just wanted to make sure I could do it or rather take the right stepthanksKenny

No. Your Macbook Pro requires RAM running at 1066mhz... This RAM runs at 1600...

I would say that they're the same thing. Looking at your laptop specs, it does support low voltage RAM. I don't know why you might need so much RAM with a slow processor, cause you wouldn't be able to do anything intensive, and so you won't really get the most out of it...unless you're using it as a RAM drive. But yeah it should work.

Just want to chime in for anybody wanting to upgrade their Macbook Pros. Both answers are correct here. Usually faster RAM would not affect compatibility. This time however it does. If you are using a Mid 2009 Macbook Pro you need to buy RAM that is the same speed as the RAM currently in your system.

Yes, at first I thought that it was different memory I bought for my Mac, but looks like it was the same. Works fine in a late-2011 MacBook Pro.

I had to use a flash hack to roll back to earlier macbook pro 15 firmware that set it for 1.5GBs, it seems to work ok. I did read where some folks on forum said it was the SATA cable on the Macbook Pro that was the problem and they bought a newer cable and swapped it to fix it
