Crucial 8GB DDR4 2666 MT/s (PC4-21300) SODIMM 260-Pin Memory - CT8G4SFRA266

Installed on Dell Inspiron 5590 to increase the memory and worked like a charm! Had no issues and was easy to install. No errors or stability issues with the laptop after the upgrade either.

Bought as an upgrade for my laptop MSI GL75 9SDKStarted working right after installation without any tuning.CPU-Z shows full match to the described characteristics. Dual-channel mode just works.The system looks to be pretty stable and fast.Wrt performance it's probably better to buy a smaller volume bars which may come with smaller timings, but 19 is already pretty good IMO. I any case I've bought this pack to have enough volume but not enough speed, and I've got exactly what was expecting.Maybe except the price which taking account the shipment and import clearance taxes turned out to be higher than from local retailers (overall local Belarus prices are 14% cheaper for the same memory)If anyone curious there is dmidecode below:Array Handle: 0x003AError Information Handle: Not ProvidedTotal Width: 64 bitsData Width: 64 bitsSize: 32 GBForm Factor: SODIMMSet: NoneLocator: ChannelB-DIMM0Bank Locator: BANK 2Type: DDR4Type Detail: SynchronousSpeed: 2667 MT/sManufacturer: MicronSerial Number: 2F3A12AEAsset Tag: 9876543210Part Number: 16ATF4G64HZ-2G6B4Rank: 2Configured Memory Speed: 2667 MT/sMinimum Voltage: 1.2 VMaximum Voltage: 1.2 VConfigured Voltage: 1.2 VMemory Technology: DRAMMemory Operating Mode Capability: Volatile memoryFirmware Version: Not SpecifiedModule Manufacturer ID: Bank 1, Hex 0x2CModule Product ID: UnknownMemory Subsystem Controller Manufacturer ID: UnknownMemory Subsystem Controller Product ID: UnknownNon-Volatile Size: NoneVolatile Size: 32767 MBCache Size: NoneLogical Size: None

As of the time that I'm writing this, it has been about 4 years since I bought this RAM stick. This RAM stick has survived and continued to work flawlessly for all the time that I have used it in my laptop. I'm only writing this review because I recently upgraded my RAM from this same vendor, and wanted to share that my previous purchase (this one) worked flawlessly for what I needed it to.

This Crucial 64GB Kit (2X32GB) DDR4 2666 MT/s CL19 SODIMM 260-Pin Memory - CT2K32G4SFD8266 - works with the 2 each 4 GB 1Rx16 (single rank) SK Hynix RAM modules (each Part Number: HMA851S6CJR6N-VK) supplied by Apple in my 2019 iMac 27 inch 3 GHz 6-Core Intel Core i5 system purchased from Apple in January 2020. The Amazon description notes that the 2 each 32 GB Crucial (Micron) RAM modules (each Part Number: 16ATF4G64HZ-2G6B2) are supposed to be "Single Rank", but they are clearly marked as "2Rx8" (dual rank) on the attached label. Utilizing existing 2 x 4 GB modules, 72 GB RAM total (all running at 2667 MHz) was installed in the following configuration (Bank 0 at bottom of cavity) in about 15 minutes: BANK 0/Channel A-DIMM0 32 GB Crucial, BANK 1/Channel A-DIMM1 4 GB SK Hynix, BANK 2/Channel B-DIMM0 32 GB Crucial, BANK 3/Channel B-DIMM1 4 GB SK Hynix. The initial system boot after RAM installation took at least 30 seconds longer than usual, but subsequent boots have been quick. Despite not being Single Rank modules as advertised, I'm happy that I'm able to use this kit with my existing Apple provided RAM at full speed.Thanks to 'darcy' for writing your review on January 1st, 2020, at Amazon.ca to confirm that this kit worked with this system! Your review was the only one anywhere across the Internet confirming this Crucial 2 x 32 GB kit in a 27 inch 2019 iMac. Hopefully the model numbers in this review are useful data points for future Crucial, Amazon, and Apple customers. Thanks for quickly delivering a quality product at a reasonable price.

Arrived just as I expected. Genuine packaging, easy installation

Las memorias Crucial tienen muy buena calidad, pero en mi caso no funcionaron correctamente con mi Acer Predator porque la velocidad que soporta mi PC es menor a la de estas memorias, así que fue más una mala decisión de mi parte.El sistema se colgaba durante el trabajo, pero el proceso de devolución fue muy eficiente.Este año ya conseguí unas que sí fueron 100% compatibles y funcionan perfecto.

Worked great for me.

Simplemente genial. Fácil de instalar, funciona a la perfección y la mejora de rendimiento es muy perceptible. Mi PC ahora se siente mucho más ágil. Crucial nunca decepciona.
