DDR4 RAM 8GB 2666MHz PC4-21300 SODIMM Laptop Memory | Non-ECC PC4-2666V CL19 260-Pin SO-DIMM 1.2V Notebook Computer Memory Upgrade Module

Bought this to give my 2019 27-inch iMac some breathing room, and it delivered. Installation was straightforward, the iMac recognized the full 32GB right away, and the difference was obvious the first time I sat down to work — apps open faster, switching between a pile of browser tabs and editing windows doesn't bog down the way it used to, and the whole thing just feels less "stuck." Honest caveat: I've only had it installed two days. But RAM isn't really a "break-in" component — it either runs clean and stable or it doesn't, and so far this has been rock solid with zero hiccups. The only thing two days can't tell me is long-term reliability, so I'll come back and update if anything changes. Who I'd recommend it to: if you do real work on your computer — lots of tabs, photo or content editing, anything heavy — this is a genuinely worthwhile upgrade and cheaper than I expected. If you're mostly browsing and email, you may not feel it as much. Honestly, next computer I buy, I'd put this in from the start.

Purchased this RAM to add to my QNAP NAS. They were easy to install and proved to be a solid upgrade. I noticed an improvement in performance from the 8GB that came with the unit. The RAM shows up as 32GB as stated. One thing to note - the NAS specs noted a max RAM capacity of 16GB, but some online research indicated that 32 would work. I can verify that the NAS has run flawlessly for the past month with this RAM installed. I'm happy with my purchase!

Bought this to add to a Dell laptop that needed an extra stick of memory. It seems to be 100% compatible with the stick that was already in the laptop, as claimed by the manufacturer. The laptop is still working great about a month after the memory was installed.

Works great hooked it up right away my laptop is running a lot faster now

memory worked on me HP 15-bs212wm I tried to use 32gb and 16gb memories and they didn't work because my laptop is only compatible up to 8gb, previously I had a 4GB one and the performance was very low, with this new 8GB memory the speed improved considerably, I was thinking of throwing away the laptop but now with the new 8GB memory I am giving it a new opportunity

note: This is in response to the other review titled "Scam Stick Sent" that was posted on August 20, 2021. I also bought the same RAM from Amazon and installed it in my laptop, only to see 5.9GB free/available for the system to use ...so why is the advertised/printed 8GB not being shown? What’s going on!?! If you look at one of the pictures that the other reviewer posted, specifically the one that shows the BIOS (i.e. shows that they have an Acer Aspire A515-43), you'll notice near the top that this laptop has an AMD Ryzen 3 in it. I don't have the same exact laptop as this other reviewer, but mine has an AMD Ryzen 3 in it as well. This is important to note because these AMD Ryzen 3 chips are actually APUs (Accelerated Processing Units) which in very basic terms combines the functions of the CPU and GPU on a single die. In other words, this APU also serves as the iGPU (integrated Graphics Processing Unit) for the system. The reason why we're seeing 5.9GB of available RAM is because a portion of the installed 8GB system memory has been allocated for the APU/iGPU to use since it doesn't have its own dedicated memory, a design called "shared graphics memory" (go ahead and Google it for more info). If you’re lucky, you might have a setting in your BIOS that allows you to adjust how much memory to allocate to the iGPU (though you won’t get the full 8GB back since the iGPU still needs some memory allocated/shared to it so it can function in the first place). Unfortunately, I did not have that setting in my BIOS so I ended up buying a 16GB RAM stick off Amazon from a different manufacturer (Team Group for the curious out there). To no surprise, the system reports only 13.9GB of memory being available! (This is plenty sufficient for my use case, though.) What’s more important after installing any new RAM in your system is to boot MemTest86 off of USB or CD and test your newly-installed memory for any errors. As of this writing, the current version of MemTest86 (from Passmark Software) runs 4 “passes” of tests on the RAM. If you can get through all passes with no errors, then it is safe to say that your RAM is stable. If not, then return/replace it right away with Amazon’s hassle-free return process. Even if you passed the return window, most manufacturers offer a “lifetime warranty” on their RAM so you’ll have to deal with them instead (and your mileage may vary in that regard). Oh yeah, there's a similar test program called MemTest86+ which is a fork of the one from Passmark. It's also great, but I don't use it because it's not being actively updated (the latest version is a beta from 12/4/2020). My motivation for writing this review is to clear up some confusion and dispel any worries because that other review may mislead others into thinking they’ve been “scammed” when that might not necessarily be the case. I’m not saying the other person didn’t get scammed, but it seems highly unlikely given the fact that A-Tech is a reputable company, Amazon is handling/fulfilling the order, and the white label on the package (as shown on the first image) acts as a tamper-proof seal so you’ll know right away if the package has been opened already. tl;dr If you have an AMD APU in your laptop, you won't get the full advertised 8GB available for your system because some of it is being shared/allocated to the APU. (If your BIOS has that particular setting available, then you can adjust that allocation amount). Also, run MemTest86 immediately to check your RAM for errors!

Installed along with SSD in Dell laptop. Works well.

Fit my Dell desktop micro tower, the dram installed easily. Great product and the maximum capacity that the computer will handle. the company offers great Tech support. Great price at the time.
