## Questions & Answers

**Q: Does the full 6gb read (meaning being used) on the macbook pro once installed? i heard the mbp mid 2007 has a max of 4gb and thats all it will use.**
A: I don't know about MacBook Pro. But I successfully installed this 6GB dual card (4GB + 2GB) for RAM expansion in my mid-2007 20" iMac. According to Apple support, my mid 2007 iMac's RAM could only be expanded to 4GB. So far so good with the 6GB expansion. I breathed a little more life out of my iMac.....

**Q: Is this compatible with Mac Pro 1,1?**
A: Hi Renee!  Unfortunately this would not be the proper RAM upgrade for this computer.  The Mac Pro takes full-size DIMMs, which is available on Amazon. If you have more detailed questions feel free to get in touch with our expert support team at owcdigital.com/supportHave a great day!

**Q: what is the warranty on this? Is it the same lifetime warranty as on Macsales.com? Or is it less?**
A: yes it  has lifetime warranty

**Q: Why is the 4GB sticks so much more expensive than the others?  Is it manufactured differently or is this simply supply and demand economics?**
A: The memory modules required to make the 4GB sticks are very hard to come by today, it is simple supply and demand.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Reviving an old Netbook - this works nicely
*by C***S on June 20, 2023*

I found an old netbook at a pawnshop for $20. It worked but not well. I had the exact same one in 2009 when they were brand new and I loved that old thing - still have it in fact, but wanted another one for... stuff...Anyway, got it home, found out it only had 512k - so got a 1gb ram (max out) and did the tear down to get it in. I should note I gave this 5 stars for "easy to install" - it's not the rams fault that you have to basically disassemble the machine to get to the ram slot. Once you get there, it just snaps in, though...Swapped this, the battery, put an SSD drive in it, and it is a great little appliance type tool for about the cost of a new tablet. And it will run Linux great as well as Win10.

### ⭐⭐⭐⭐⭐ High quality RAM at a great price!!
*by M***L on January 20, 2016*

I ordered this RAM for my daughter who has an older Macbook. The RAM came in VERY quickly and was exactly as I ordered. I have heard that OWC has some of the best products on the market, and I wasn't disappointed with the memory upgrade kit.The installation is quick and very easy. The memory itself doesn't come with any installation instructions, but just refer to the Apple website or do a quick search for how to install the memory. It will require a coin (to unlock the battery) and a VERY small phillips screwdriver.The installation took less than five minutes, and after install the computer functioned flawlessly and recognized the new RAM with no issues. I highly recommend OWC products for all your computer needs.

### ⭐⭐⭐⭐⭐ Fits A1811 macbook
*by L***E on July 4, 2019*

Used to upgrade my old Macbook and repurpose it as a Linux machine. Fits A1811 perfectly - although Apple officially only supports 4 GB on these models, tinkerers have discovered that the MoBo will actually take up to 6 GB without issues (beyond that, performance nosedives). This mismatched combination (4 + 2 GB) is the perfect solution to the problem I had, and this is why I bought it. Works great! My machine running Lubuntu can see/use all 6 gigs no problem.
