Crucial 8GB Single DDR3/DDR3L 1600 MT/s (PC3-12800) SODIMM 204-Pin Memory For Mac - CT8G3S160BM

The memory modules eventually worked perfectly and rock solid, but it took awhile to get there. What I really appreciate about this order is the speed with which the retailer shipped the memory. I placed the order on a Thursday and the memory sticks were delivered by USPS on Saturday. This was for standard non-Prime shipping. Plus, the price was very affordable in an era of unbelievable prices for system memory. Granted, this is only DDR3/DDR3L memory, so way below the radar in the memory world for AI systems. The Crucial memory modules eventually worked fine, but I had to adjust the BIOS settings on my old Intel DQ77KB motherboard PC from "XMS1600" to "Automatic". Once I tried that setting, the system POSTed as it should and life has been much, much better at 16GB memory. I don't know why or what changed, but lately my system was hanging if I had even four tabs open in Chrome. Maybe Microsoft made a change in how Windows 10 handles program memory, I don't know, but I do know having 16GB of system memory makes this old system much more usable. At least, up until October 14, 2026 when update support ends. My system memory usage with Chrome with four tabs open now is in the 8.5GB-9GB range, which is no problem with the 16GB of RAM. My recommendation, if you can't upgrade memory on your old system, is to use Brave in place of Chrome. FWIW.

Works great.

I replaced an older iMac with a Late 2013 27" iMac (3.2 GHz i7, GTX 780M 4GB, 1.28TB Fusion Drive) with 16GB of RAM in November. I planned on upgrading to the max 32GB of RAM at a later date. I held off upgrading due to mixed messages about the differences between the Crucial RAM Amazon was selling here and the recommended RAM on Crucial's website (which was more expensive). It seems like the dust had settled so I ordered two individual 8GB modules since the price was slightly less than the two-pack package at the time. Although I had concerns about fit, etc., my main concern was voltage requirements since higher voltage generally means more heat; heat being an enemy of electronics, particularly computer components. My understanding is that my particular model of iMac employs 1.35v RAM. Crucial's website specifically states that their recommend RAM is 1.35v. The Crucial RAM Amazon sells here is listed as 1.35v/1.5v. Just prior to ordering I contacted Crucial directly to be sure the RAM Amazon was selling was compatible with my model of iMac. MY EMAIL TO CRUCIAL: "Hello, Can you please tell me what the difference is between Crucial Part Number CT4951624 and Crucial Part Number CT2K8G3S160BM? Specifically I want to buy a 1.35v model. Part Number CT2K8G3S160BM is listed as 1.35V/1.5V. Thank you very much!" CRUCIAL'S REPLY: "Thank you for contacting Crucial. I have looked at both of the part numbers you sent in your email, and these are actually the same. The difference between the number CT4951624 and CT2K8G3S160BM is that the smaller one tells us that CT2K8G3S160BM is guaranteed compatible with your specific system. The longer part number, is considered a general part number that can be compatible with thousands of types of computers. That smaller number can vary from system to system, but the the general part number will not change. Essentially, CT4951624 simply tells us that this module is compatible with your system. Regarding the voltage, the fact that it is listed as 1.35v/1.5v means that it will work with either voltage. So, if you are looking for a module compatible with 1.35v you can buy that part. Additionally, if you were looking for one that worked at 1.5v this part would still be compatible. I hope this information has been helpful. " I also read several reports about the Crucial/Amazon modules being hard to seat...needing some force to get them in. Mine slipped in without any pressure at all, a perfect and easy fit. Other reviewers also mentioned having to wait a long time for a reboot or having to reboot twice with the Crucial/Amazon RAM. My iMac booted up normally the first time. So Crucial may have changed some of the specs from what was being sold here early on. SUMMARY: Since installing this Crucial RAM my iMac has been running flawlessly. So based on my personal experience the Crucial RAM being sold here by Amazon is a perfect fit! I'll update my post should I run into anything unusual. Hope that helps anyone that follows!

I installed it myself last month. So far, so good! I'm very pleased.

Purchased x2 8 gb ram sticks to upgrade my late 2012 mac mini and it works great!

Very good quality and fast delivery. Thank you so much.

It didn't greatly improve the games I expected too, but it did greatly improve other games and the main thing is that it works.

If I knew it was going to be so easy to change out I would have done it years ago. Not being to hardware savvy I balked at the idea of replacing my 4gb ram on my MacBook Pro until I got tired of watching the color spiral of delay as programs fought to get ram to load. I read a review on this product and saw a simple tutorial and I can't tell you how much faster my Mac is running. MY computer had 2-2gb ram cards and i replaced 1 card with this 8gb card and am now running 10gb and problems solved. If you have 15 minutes,a table,micro/mini phillip screwdriver(eyeglasses screwdriver),you turn off your Mac completely,and unscrew bottom cover,remove it and the ram slot has 2 little hinges 1 on each side that you press and the installed factory cards will pop up.Simply pull 1 or both out and insert new ram and your done.! I highly recommend this product!

Ero alla ricerca di una ram da sostituire in un vecchio macbook del 2012, dato che le sue originali 4 ram non bastavano più per le ricerche quotidiane. Ho optato quindi per le crucial che si dimostrano ancora essere una sicurezza. L'imballaggio non è chissà cosa di fantastico, anzi molto classico e standard. Si mostra in un suo piccolo contenitore con copertura in plastica, facile da aprire. La ram è stata facile da montare e non ho avuto nessun problema. Il computer ringrazia.

This item is good - thank you No issues

In my experience, Crucial is a good brand for RAM and SSD products. Very reliable and robust. I bought this product for increasing the RAM on my old Lenovo Thinkpad X230 which has now seen a new lease of life with this 8GB RAM. Most people don’t realise that they can increase the performance of old laptops by just increasing the RAM and upgrading storage to SSD as most time consuming operations are RAM and disk read/write operations.

I ordered a couple of these to place in my Synology DS1817+ and upgrade it to 16gb of RAM. At the time, it turned out to be cheaper than buying a 16gb set. Works great in that device.

I picked up a 2012 MBP on the cheap with hopes of putting 8gb of RAM in and an SSD to bring it up to speed for modern tasks. One 8gb stick of this was a pretty cheap upgrade, so I went for that so I have the option to install another 8gb stick in future if needed. It arrived safely packaged and took me all of 5 minutes to install. Booted up no trouble and has given me a considerable boost in performance (even without an SSD).
