TEAM ELITE 4GB 2666MHz Laptop RAM

TEAM ELITE 4GB 2666MHz series has released an all-new DDR4 SO-DIMM product which is compliant with JEDEC international standard. With only 1.2V of working voltage, it can save electricity use by 20% compared to its last generation. Therefore, the heat generated from the product itself can also be reduced and maintain the surrounding temperature of the system. It is 100% compatible with INTEL's latest X99 & Skylake chipset. With selected high-quality IC chips and strict testing standard, it is the perfect choice for laptop users, who seek for excellent quality, optimal performance, stability and compatibility.

TEAM ELITE 4GB 2666MHz Laptop RAM Review

I bought this to upgrade my laptop from 8 to 16GB and it worked great. I picked this one because it was the cheapest LP-DDR4 2666 8GB I could find at the time. Installation was easy - just take the bottom of the laptop off, pop it in, and boot it up. Another review mentioned that the RAM shows up as being clocked at half the advertised speed - this is not false advertising or a mistake but the way RAM works. DDR RAM transmits data *twice* per clock cycle (Dual Data Rate - the "DDR" in DDR4). When you see RAM sold as 2400, 2666, 3200, etc, MHz this is the "effective" clock rate. Whatever it is , the actual clock speed of the RAM will be half of that (regardless of manufacturer) for DDR RAM. Listing RAM speeds in MHz is wrong and potentially confusing (it should be MT/s) but I can't take any points off for this since all the RAM manufacturers do it. Keep in mind when buying RAM that if you mix two different speeds (e.g. 1 stick of DDR4 2400 and 1 stick of DDR4 2666) it will work but both will be run at the slower speed of the two. If you're adding an extra stick of RAM, check what speed you have already before buying, and then buy that kind. Or, if you want faster RAM than what you already have, it's best to replace all your RAM sticks.
