Instead, it recognized all 24gb of ram, but the system under clocked all of it to 1600. This is what it says in the RAM overview: 24 GB 1600 MHz DDR3 So it seems that unless you match the 1867 mhz of the original apple ram, and you leave the apple sticks in there.

Click to expand.Again: - JEDEC standard is 1866 MHz (or PC3-14900). The actual frequency is 18777 (1866 + 2/3) MHz. Apple marketing at work here. - 1866 MHz = 1867 MHz - DDR memory is accessed in pairs by the memory controller. So Slot A+B = channel 1, slots C+D = channel 2. - Don't mix and match SODIMMs with different clocks and CAS latencies. DDR controllers usually have two channels and to operate efficiently, it's recommended to have identical modules in all four slots.

A config of: Slot A: 4GB Apple SO-DIMM @ 1866 MHz (or 1600 MHz) Slot B: 4GB Apple SO-DIMM @ 1866 MHz (or 1600 MHz) Slot C: 8 GB Brand X SO-DIMM @ 1866 MHz (or 1600 MHz) Slot D: 8 GB Brand X SO-DIMM @ 1866 MHz (or 1600 MHz) is ok. I would also keep the Apple SO-DIMMs in the lower slots. AFAIK, the original 1600 MHz DDR3 modules were CL11, NON-ECC, DDR3L (@ 1.35V). Looks like OWC is selling 1866 MHz modules with CL11 for the 2015 models. Click to expand.It is because of CAS latency indeed: I don't know why, but the controller prioritize CL over speed. When you mix CL13 and CL10 modules, the controller runs all modules @CL10, and to do so, it must slows down the 'Apple RAM' module, which can't support CL10 at 1866/1867 MHz.

So everybody runs @ 1600 CL10. That's why when we learned the 'Apple RAM' was CL13 I told you to buy 1866 MHz CL13 modules if you mix with stock RAM, and to take faster modules (frequency or low latency) if you remove stock RAM.

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 laptop memory The fastest, easiest way to improve your laptop‚s performance There‚s an easy cure for a slow computer: more memory. Designed to help your system run faster and smoother, Crucial Laptop Memory is one of the easiest and most affordable ways to improve your system‚s performance. Load programs faster. Increase responsiveness.

Run data-intensive applications with ease, and increase your laptop‚s multitasking capabilities. Make everything on your computer faster Memory is a component in your computer that allows for short-term data access. Since your system‚s moment-to-moment operations rely on short-term data access – loading applications, browsing the Web or editing a spreadsheet – the speed and amount of memory in your system plays a critical role. Load apps in seconds by increasing the speed of your memory and installing more of it. Multitask with ease If you‚re like us, you use your computer to do lots of things at once. You might be editing a document, while also looking at pictures and browsing the Internet. This naturally leads to a performance problem: every app you‚re running requires memory and competes for a limited pool of resources.

Overcome this by installing high-density modules in each memory slot for seamless multitasking. Extend battery life One of the most important aspects of laptop performance is battery life. By upgrading your memory, you can potentially take advantage of lower voltage modules – and increase energy efficiency by up to 40% when using the latest memory technology. 1 What‚s more, by simply installing more memory, you‚ll reduce the number of times your system has to access the hard drive (paging).
