Why to upgrade RAM - Boosting Your Mac's Performance.

The ideal way to increase Your Apple Systems - MacBook / MacBook Air, MacBook Pro, iMac, Mac Mini and Mac Pro is to upgrade RAM Memory and Storage Memory. 

Unlike Non-Mac PCs and Notebooks, Apple has been revolutionary in making their hardware and software remain sophisticated. Surprisingly, it is easier to upgrade RAM memory on all Macs for a novice user. 

Before we start finding a compatible memory for Your Mac, we'll start with a brief introduction to Memory, RAM Memory and Storage memory

Memory is information or data acquired, retrieved. In order to store this data, we need storage memory such as Hard Disk or SSD (Solid State Disk).

To process this data back and forth, we need a temporary storage device known as RAM memory.

When data builds up in storage, we need more space to continue saving data. Likewise, when huge data is processed, RAM memory will run low. Usually, we are accustomed to delete data from storage to make way for more data, or close other applications to make way for a certain data or applcation to work better. Subsequently, the Mac or PC will slow down and end in 'low memory' errors*

To counter this issue, it is necesarry to upgrade RAM memory with a faster speed, better throughput, less latency RAM memory. Standard memory that ships with Macs can be 4 GB or 8GB. Sometimes, standard memory can be the maximum memory supported.

To find the maximum size, memory type, memory speed supported, you can visit for technical specs or enter your Apple Serial Number in a popular, trusted website as everymac is a informative website that provides specification for any mac. Standard and Maximum RAM supported can be viewed in both these sites.

With a few exceptions for some Models, upgrading RAM memory for your Mac does not void Apple Warranty. 

One other easy way is to contact our RAM memory Experts at Memorystock. We provide support by live chat, email and phone. 

It takes very little effort to speed up your Mac, dramatically. So why wait, log on to for compatible, inexpensive quality RAM for your Mac. While it is easy to find cheap RAM memory, we recommend to purchase from a reliable source, especially for Mac.

To further increase your Mac Performance, you can upgrade the Processor of your mac, but it is not inexpensive or easy as upgrading RAM memory.

*low on memory errors can also be a flaw in the software.

DDR3 RAM memory for desktops and laptops - MemoryStock

22. April 2016

DDR3 RAM Memory for laptops and desktops were introducted to market during 2007 and has been in use since then to the present.

Sucessor to the DDR2 memory, these are all based on SDRAM (Synchronous Dynamic Random Access Memory). DDR stands for Double Data Rate - meaning data is transferred twice the time. The actual clock rate at which a memory under DDR3 design works is double, to the speed at which it can operate. A PC3-8500 1066 MHz memory is double the speed of the actual speed at which it works, 533 MHz and so they are labeled as 1066MHz speed rather than the real maximum clock which is 400 MHz.

If a certain system was designed to acess memory system at 1066 MHz, then a 1333 MHz Ram memory will not work at 1333 MHz, it will instead read at 1066 MHz, and in some cases, the system will remain incompatible to due to the higher speed, unsupported by the system.

The naming system of DDR3 memory is PC3-*****. ***** stands for the maximum bandwidth of that memory. Maximum bandwidth or throughput is the number of bytes transferred in a second between the memory controller and the memory module. Note that, the maximum bandwidth is a theoretical value, and it may never transfer data at such lengths.

Alternatively, DDR3 memory is also labeled by memory speed, labeled at MHz. DDR3 PC3-10600 has the memory speed of 1333 MHz,

Some commonly used DDR3 RAM memory are:

PC3-8500 1066 MHz

PC3-10600 1333 MHz and

PC3-12800 1600 MHz

There are other faster speeds as well, designed specically for systems that support the faster memory though overclocking. DDR3 memory operates twice the speed of the DDR2 and they have a 8 Bit Prefetch. All memory designed to be DDR3 will only fit on DDR3 Slot. 

As DDR3 RAM memory came into prominence, an even low voltage consuming RAM was released in the last few years, the speeds remained the same, except for the low voltage consumption - DDR3L.The usual DDR3 consumes 1.5v, lower than it's predeccessor DDR2, while the DDR3L RAM consumes at 1.35v. The lower voltage memory will work on both DDR3 and DDR3L slot, but not the other way around. 

DDR3 memory for laptop can be identified by the size of the memory, as well as the number of pins present in a DDR3 SODIMM memory  - 204 Pin. And,

DDR3 memory for the desktop has 240 pins and is usually reffered as DIMM. They both are non-interchangeable due to the physical dimension difference.

DIMM is for Desktops and SODIMMs for laptops / All-in-One PC's and some motherboards.

There are other terms related to DDR3, GDDR3 is for the Graphics DDR3 Video memory; LPDDR3 for the mobile DDR3 RAM.

To find memory for your laptop or dekstop supporting DDR3, check out our website or contact our live chat support with the model number and we shall assint to a relevant, compatibe speed recommended by the manufacturer of your system.

RAM Memory Latency vs Throughput - A real deal.

20. April 2016

Latency - The time required to perform an action or to produce a result.

It is measured in units of time - Hours, minutes, seconds, nanoseconds and clocks.

Throughput - The number of actions performed or results produced in a unit of time.

It is referred as Bandwidth in RAM memory. The actions / results per unit of time.

Example: Boeing manufacturing 777 Airbus.

Boeing Factory manufactures an Aircraft in 83 days. The Factory manufactures 730 Aircrafts in 365 days.

Latency is 83 days. Throughput is 2 aircrafts / day or 60 aircrafts / month

Latency and throughput in RAM

Eg: DDR3 PC3-12800 CL 7

12800 MB/Sec - Maximum theoretical transfer rate. CAS Latency 7 tells us it will take 7 clock cycles delay to return a requested data.

There are other common latencies 6,8,9,11

The lesser the latency, the faster the RAM performs.

So, the next time you are searching for a faster RAM, you might want to check for a less latency compatible RAM.

Find one here at now, or use our memory scanner for an 100% compatible RAM.
