Review: Great price - Made a big difference on my laptop and easy to install
Review: Crucial 8GB Single DDR3/DDR3L - Works Great! - Today I upgraded my 2015 HP Pavilion model 13-a012cl "X360" laptop computer using the Crucial 8GB Single DDR3/DDR3L 1866 MT/s (PC3-14900) Unbuffered SODIMM 204-Pin memory chip. 8GB is the max my laptop can support. The upgrade was flawless. The difference between DDR3 and DDR4 is the number of pins on the chip that connect it to the socket. DDR3 has 240, and DDR4 has 288. Besides the pin number, DDR3 and DDR4 look physically different in length and width. Google your computer's model number or contact the manufacturer to determine which your specific model requires. My laptop is about 5 years old, and usually I have it tethered to an external 22" LG LCD monitor, so the unit functions more like a desktop box would. I thought about getting a new laptop, but opted to purchase the Cruicial RAM chip -$44, a Cruicial MX 500 1 TB 2.5" solid state drive (SSD) (CT 1000MX500SSSD1) - $120, and a new fan- $17. I also bought a Unitek USB to SATA USB-3 adapter to clone drives - $19. So for around $200, I have essentially a new computer. Numerous publications over the years have cited adding additional RAM memory as the single best - easiest - improvement one can make in improving computer perfomance. Add to that SSD and a new cooling fan, and I ought to be golden for another five years. I don't do payroll for the State of California, nor do I track license plate numbers for Bejing, so to me, this was a cost-efficient upgrade. Thanks Cruicial and Adorama for the sales and support!
