Comments about Crucial 16GB Kit (2 x 8GB) DDR4-2400 SODIMM Memory for Mac: 'Works fine by itself in new 2017 27 inch imac, but computer will not start if installed with the 2 4gb original memory modules. Items 1 - 9 of 9 - Crucial 16GB DDR4-2400 (PC4-19200) CL17 SO-DIMM Laptop Memory. ECC Unbuffered CL13 Desktop Memory Module for Mac Pro Systems.
Memory spec terms If you're not sure if a module is right for your system, use the for a list of guaranteed compatible modules. NON-ECC/Non-parity Most desktop and laptop computers take NON-ECC or Non-parity memory. ECC/Parity ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses. Unbuffered Most PCs and workstations use unbuffered memory which is faster than registered memory. Registered/Buffered Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.
Fully buffered Designed for next-generation servers, features an advanced memory buffer. CL CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.
Component configuration (For example: 64Meg x 64) Indicates the size of the memory chip components on the module. Voltage For example 2.6V. Indicates the power used by the module. The lower the better. Check the and for more detailed definitions. Crucial DDR4 SODIMMs Product Highlights 1. Speeds start at 2133 MT/s.
Increase bandwidth by up to 30%. Reduce power consumption by up to 40% and extend battery life. Faster burst access speeds for improved sequential data throughput. Optimized for next generation processors and platforms. Available in modules up to 8GB and kits up to 32GB. Limited lifetime warranty 2 More speed.
More battery life. More memory capacity. Fuel your next-gen laptop. In the ever-changing world of technology, any component more than five years old is usually in need of an update. At seven years old and counting, that‚s where DDR3 memory is at: laptops can only do so much with it.
Since the introduction of DDR3 memory technology in 2007, processors have doubled in capability, SSDs have revolutionized throughput, and graphics cards have drastically increased frame rates, leaving memory as a limiting factor. With Crucial DDR4 SODIMMs, crush the DDR3 memory bottleneck and unlock a new standard of performance. More Energy Efficient Extend battery life by using less power. Operating at just 1.2V compared to 1.5V for standard DDR3 memory, Crucial DDR4 SODIMMs consume 20% less voltage than standard DDR3 technology. Crucial DDR4 SODIMMs also contain other efficiency features, for an overall power reduction of up to 40%. 1 More Density Pack more memory into your laptop than ever before.
Capacity Of Ddr4 Memory
Crucial DDR4 SODIMMs debut in densities up to 8GB, and as DDR4 technology develops, modules are projected to hit 32GB — allowing you to install twice as much memory as you could in a DDR3 system. Since laptops only have 1-2 memory slots, high-density Crucial DDR4 SODIMMs allow you to overcome this limitation and install more memory for faster mobile performance. More Speed Load applications faster and run demanding programs without lag. Crucial DDR4 SODIMMs debut at 2133 MT/s —more than 30% faster than DDR3 modules. 1 More Bandwidth Effortlessly multitask between apps and empower your system to fire on all cylinders. Crucial DDR4 SODIMMs increase memory bandwidth by over 30%, allowing your system to handle more data at once. Crucial DDR4 SODIMMs are optimized for next-gen platforms, allowing you to maximize bandwidth.
Crucial Memory For Mac
1Product performance and efficiency improvements are noted as comparisons between DDR3 and DDR4 memory technology. As of May 2014, standard DDR3 memory achieved speeds of 1600 MT/s and operated at 1.5V, compared to DDR4-2133, which will operate at 1.2V. When voltage reductions and all other energy-saving DDR4 features are factored in, DDR4 modules are projected to consume up to 40% less power. As DDR4 technology matures, speeds and bandwidths are projected to respectively hit 3200 MT/s and 25.6 GB/s – twice what was possible on DDR3 technology. 2Limited lifetime warranty valid everywhere except Germany, where warranty is valid for ten years from date of purchase.
Comments about Crucial 16GB DDR4-2400 SODIMM: My installed 128GB SSD was near capacity. The 528GB SATA 2.5' SSD offered by Crucial was a cost effective upgrade to significantly extend the life of another wise very functional, yet four year old, i7 laptop.
Ddr4 Memory Sizes
Installation was more complicated than in the documentation because the oem SSD was a micro SSD, and the bios was protected - which required downloading and using a boot loader, and ultimately removing the original oem-micro SSD. Additional challenges occurred during cloning because of recovery partitions on the oem SSD 'to the right' of the primary partition. All in all, in the end I got it done. If you are minimally proficient at following instructions and can use a #0 Phillips screwdriver (for my Acer laptop) while a bit time consuming - which I planned for - this is an easy upgrade that is well worth it.
