We at NEMIX Corp understand that RAM can be a little confusing at times and NEMIX wanted to be able to provide some common asked questions about your systems computer Random Access Memory.  

How to know it’s time for a memory upgrade?


There are multiple signs that can indicate it may be time to upgrade your memory. One key indicator is If you see your mouse pointer turn into an hourglass for an extended period of time, if you hear your hard drive running, or if your computer seems to work more slowly than you expect, the reason is probably insufficient memory. When physical memory is insufficient, the system uses Hard Disk Space as memory. This is called "Virtual Memory". Since access time of Physical memory is in tens of NanoSeconds and Access time of Hard Disk is in MilliSeconds, the system slows down considerably.

Why Does the storage in RAM erase every time the computer is shut down?


The data stored on your RAM is volatile that is not saved once it is no longer receiving electrical power.

1. It is faster to write data onto a blank slot than to delete data from a filled slot and refill it up with another set of data. Since the data it loads to the RAM is different for each session, it is pointless to store those data permanently in the RAM only to delete them on the next boot up.

2. RAM has a much high frequency than hard disk, which makes it ideal to store temporary files so the CPU can process them faster without having to wait for the slow hard disk. With an initial empty state, the system will be able to load as many temporary files as possible onto the RAM without slowing down the whole loading process.


What is the Key Benefit of Upgrading Computers Memory?


Upgrading your memory is typically the easiest and least expensive way to upgrade your computer for a significant increase in system performance. The computer's RAM memory is its workspace, or where all of the instructions it needs to act on are stored temporarily. A memory upgrade is particularly helpful for users who work with large files, have more than one program open at one time, or use memory-intensive applications such as games or graphics and video editing software. The extra memory becomes allocated to the opening of several programs at the same time. RAM upgrades are thought to speed up a computer; however, helps your system to avoid bottlenecking when trying to run a lot of high-memory programs.

What is the difference of Sdram and Rdram?


SDRAM stands for Synchronous Dynamic Random-Access Memory. RDRAM stands for Rambus Dynamic Access Memory. Two totally different types of memory with different technologies. RDRAM was developed by a company called Rambus, Inc. RDRAM. Extremely fast and uses a high bandwidth channel to transmit data speeds much faster than SDRAM.

What is Sdram?


SDRAM is designed to synchronize itself with the timing of the CPU. This enables the memory controller to know the exact clock cycle when the requested data will be ready, so the CPU no longer has to wait between memory accesses. The clock is used to drive an internal finite state machine that pipelines incoming commands. The data storage area is divided into several banks, allowing the chip to work on several memory access commands at a time, interleaved among the separate banks. This allows higher data access rates than an asynchronous DRAM.

What are RAM speeds?


Memory Speed is the amount of time that it takes RAM to receive a request from the processor and then read or write data. Generally, the faster the RAM, the faster the processing speed. For example, NEMIX RAM page has categories for DDR3 RAM running at 1,066MHz, 1,333MHz, 1,600MHz, 1,866MHz and 2,000MHz and over. The higher the speed, or frequency, the faster the RAM can read and write data, and the faster your programs will run. Check your motherboard’s manual to see what RAM speeds it can cope with, or just make sure the RAM you buy matches the speed of any RAM already in your computer: after all, there’s no point buying fancy fast RAM if you’re not going to run it at its rated maximum.  


What is it the difference between RAM vs. ROM


Read-only memory, or ROM, is computer memory containing data that can only be read, not written to. ROM contains boot-up programming that is used each time a computer is turned on. It generally can't be altered or reprogrammed. The data in ROM is nonvolatile and isn't lost when the computer power is turned off. As a result, read-only memory is used for permanent data storage. Random Access Memory, on the other hand, can only hold data temporarily. ROM is generally several megabytes of storage, while RAM is several gigabytes.

We at NEMIX RAM offer reliable, high-performance memory designed to fit your needs. We offer a wide variety of options in DDR, DDR2, DDR3, and DDR4 UDIMM form factors with speeds ranging from 266MHz (PC-2100) up to 2666MHz (PC4-21300) and capacities from 1GB all the way up to 64GB.
