Proper RAM Voltage in New MacBookPro (1.35 vs. 1.5)

Thank you. OWC is more expensive than Crucial, 148 vs. 92. Why do you recommend OWC ?

OWC ($148): http://eshop.macsales.com/item/Other%20World%20Computing/1600DDR3S16P/

CRUCIAL ($92): http://www.crucial.com/store/listparts.aspx?model=MacBook%20Pro%202.6GHz%20Intel %20Core%20i7%20(15-inch%20DDR3)%20Mid-2012&Cat=RAM

Because as a vendor they are better than anyone else, if it is cheap you want go elsewhere.

They are both great. I've used both several times, I've never had a problem with the ram from either. If you do, they will both replace it, not problem. I tend to OWC because they are usually just a tad less expensive than Crucial, but maybe not this time.

This pair, purchased on a $75 offer from Amazon,

tonite is nestled comfortably here:

Tried to eat up 16GB of RAM a little while ago. Ran out of apps to run, and still had 3GB unused.....

Fine. What makes them "better" ? Have you had personal experience with them, or did you read reviews ?

I have purchased from OWC for a very long time, ram, drives, other accessories. So far my experience with them is flawless and at this point (even though I have nothing to say against crucial) I would pay the extra money and buy from OWC

Personally I wouldn't. Even if the price for something was the same or a little less.

Simple fact is both Mac and Win PCs use the exact same hardware. There is No hardware in a Mac that would not work in a PC. There is No hardware in a PC that would not work in a Mac. At leat not any hardware that cane be user bought and replaced. So this whole thing about a vendor being Mac Specific is just a bunch of BS. Although they advertise as the pplace to buy Mac parts. Those same parts can be bought anywhere. That is unless they are originally designed to only fit inside a specific Mac notebook. But the same goes fopr a Dell notebook. You couldn't install a Mac specific design part in a Dell notebook.

Service counts but for RAM Crucial has a Life Time Warranty. And although I have only seen it used once, by a friend on RAM that was 4+ years old and died from heat (because my friend had his desktop computer in a cabinet with the door closed), Crucial sent out the new RAM with a return label and once the old RAM was returned his CC was not charged.

None of which has anything to do with the fact that in my dealings with them OWC have been better in all respects, you can buy what you want where you want but note that I don't agree, thanks.

There is very little poor-quality, failure-prone RAM on the market today. Reports of folks getting RAM that will not work in their Mac are almost exclusively due to getting the wrong parts for their Mac from a Vendor who is clueless about requirements for Macs. The issue is not "best quality" but rather "correct modules to work in your specific model".

Despite arguments to the contrary, the airflow in a Mac Pro is not the same as that in most PCs (it is lower), so Apple-rated heat spreaders are required for that Application. In addition, Apple-qualified temperature sensors are required for use in all Macs, to ensure proper fan control. Modules with the wrong heat sensors or no heat sensors may get too hot (leading to premature failure) or may run the fans at top speed all the time.

I stand by my statements above:

• Buy from Vendors with specific Mac expertise. This includes OWC, Crucial, Kingston, and Data Memory Systems, among others. In my opinion it does not include direct purchase from Memory-makers such as Hynix, unless they offer "Guaranteed or your money back" warranty. (They get it right because It costs them money to get it wrong.)

• Vendors should offer a Lifetime warranty. (This ensures they never sell junk memory, because it costs them money to replace it if it fails before your computer is obsolete.)

If I have these guarantees from the vendor, I can buy memory from any reputable Vendor, anywhere these terms are met.

Again there is NO specific RAM just for Mac's. It is based on the Intel chipset used in the computer. If a Mac and a Win PC use the same Intel chipset the same RAM will work in both systems without problems.

This is Fact Not Fiction.

Memory that meets my recommendations above is not substantially more expensive, and comes to you risk-free.

Why take chances?

Actually it is the same from Crucial. No chances taken when buying from them.

32GB is the actual maximum ram on the model. But no 2x16GB memory sticks are available right now...

Dear MAC support,

I use mac mini 2012 late. Today im change 1 ram bank(2 Gb Hynix 1.5 v) to 8 Gb Corsair CMSA(1.35v for Apple PCs). Now i have 8Gb Corsair(1.35v) at BANK 0 and 2 Gb Hynix (1.5v) at BANK 1 and working freg. is 1600 Mhz.

This is normaly?? Can i using 2 different memory in one mac mini?? Or Im must remove old 2Gb RAM form mac mini ASAP??

Vekslyarsky, Dmitry,

No one from Apple here - we're users just like you.

You may want to post in the Mac mini forum ->https://discussions.apple.com/community/desktop_computers/mac_mini as this is the MacBook Pro forum. And start your own thread - you're more likely to get responses with your own thread.

Good luck,

Clinton
