[DDR2] Never had an issue (knocks wood) with OWC RAM.

[CL4] Just upgraded my QNAP TS-451 with this pair and it worked flawlessly. The specs match the Crucial 8GB kit, but at a cheaper price point.

[6 x 3.5 x 0.6"] This kit was easy to identify following the prompts and choices on the website. It arrived quickly, and was easy to install following Apple support guidance.

[2x 2 GB] Although I originally ordered this for my mac (that is until I found out, the ram is soldered to the motherboard), I found good use on my old laptop. It made it run way faster.

[1.8 V] I've been ordering from B&H for over a decade (photo+computer) - they have the best of the best technical support team - both as a 'Live Chat' or phone call. This is so important for my work and my students. They are generous with their time and sharing expertise.

[2x 2 GB] Just installed the new 'sticks' from OWC. My Mac desktop coughed, blinked and then hit the digital highway full speed ahead. The added RAM increased speed for my editing chores with Premiere and decreased my frustration with a timeline that constantly stuttered. Thanks OWC. And thanks to B&H for a painless on-line ordering experience and quick delivery.

[1.8 V] I had an older Macbook that needed memory. I couldn't figure out which ones to buy. I hit the chat button at B&H, gave them the model number and in less than 30 seconds i not only get an answer, I get the link to the memory. I click on it, order, pay, and in two days it is on my doorstep. Took 10 minutes to install, works perfect. Thanks B&H.

[4 GB] My Mac Mini (late 2012) was sluggish brand new out of the box. It was so frustratingly slow I have rarely used it since purchasing in 2013. So I finally decided to do this upgrade. Why on earth did I wait so long?! I am very pleased with this memory kit!

[DDR2] Bought these and an SSD to upgrade an old iMac 2010. The performance difference is so vastly amazing that it feels like a new computer. Almost threw it out before.... good thing I didn't

[2x 2 GB] I have an iMac, late 2014, had a total memory of 8GB (2 x 4G). Kept freezing during Lightroom, took me so much longer to do anything just waiting. I upgraded to 16 (2 x 8GB), everything’s working great now, no more freezing! I chatted online with someone at B&H to be sure these would work on my system. As always, B&H super helpful, easy to order, shipped quickly- even during the Coronavirus shutdown! I was shocked at how easy it was to replace in my system. Took under 5 minutes! Apple made it easy to, full description from system info.
These were reasonably priced and I feel like my older computer is new again!
