Samsung 16GB DDR4 PC4-21300, 2666MHz, 288 Pin DIMM, 1.2V, CL 19 Desktop RAM Memory Module

Recommended RAM for Dell XPS 8930.Dell limits the memory’s speed to 2666mhz. This is the fastest OEM recommended stick for the Dell XPS 8930 machine.Many sticks that have a higher rated speed actually have a low native speed (2133mhz) but are overclocked. The dell XPS 8930 will only recognize the native speed.This is the fastest memory I can buy and works flawlessly with my Dell XPS 8930. It’s also cheap.

I purchased memory for older desktop running as media server. Works perfectly. Shipped very quickly from seller. Memory arrived 2 days sooner than expected. It was also very well packed in bubble wrap.

This Genuine Samsung part was identified using CPU-Z as being authentic(see screen shots) and I don't think the best counterfeiters could possibly fool this program. The new UDIMM occupies Slot #1 in the attached photos.M378A2K43CB1-CTD matches with the stockM378A2K43DB1-CTDManufactured March 14, 2020 so it is new in the sealed plastic anti-static box, made in Philippines as it should be.64-Bit system now operates in dual channel mode quadrupling the clock rate.I'm totally happy with this easy and effective upgrade. Solid buy, easy install. The first boot takes a little longer since the BIOS needs to adjust to the new clock speed and memory addition. Be patient! It takes care of itself!

I have a pre-built system from HP, this is the ONLY memory I found that runs at 2666mhz SPD. 99% of memory out there has an SPD frequency of 2133mhz and relies on Intel XMP to get the memory to run faster. Since I do not have XMP in my bios this was the ONLY memory that would run at full 2666mhz speed.HUGE downside, the packing of the memory is terrible, wrapped in aluminum foil and plastic, sent in a bubble mailer. Seriously about as well as I could do at home. No cardboard or plastic tray to prevent flexing or cracking of the modules during shipping. I am amazed that it survived and now constantly worry if the memory will actually be reliable in my machine. Seller needs to step up and get some flex resistant trays or send them in a very small cardboard box, just something to prevent flex/bending of the sticks during shipping

wanted to speed up my 3 yr old HP Pavillion and HP got the CPU info wrong, but the RAM I just read the label and bought Samsung, since it worked in the past. So the PC picked up the pace a little.... since I can't get much off an Intel i3 or 3i with 4 cores. Very Happy this worked. :)

I liked the fact that this is Samsung memory, not some off-the-wall outfit that I never have heard of.I liked that was made in the Philippines, not China. I liked the price. In fact, I liked the improvement to my computer's performance that I just ordered another 16 Gb. Be advised that depending on your computer, it can take considerable effort to seat the memory in the socket. Mine is a Dell.

Works as described!

What is there to say. In my 40 years in technology I found that Samsung is synonymous with top-quality! All have the same CAS latency and have had no problems after running constantly for a couple weeks. I expect to get five-plus years out if this memory of 64GB!
