Selecting the correct computer memory upgrade is overwhelming. There are about a million different sizes, speeds, types and manufacturers. This is why we found approval winning Crucial to be such an outstanding product. The search option on the main website is phenomenal and you will be able to quickly find the right RAM upgrade for your computer. The website and the reliability of this product help it stand out from the competition.
Because there are so many different computer memory upgrades available, we chose to review a DDR3 product with a speed of 1600. This speed and size is common and usable in quite a few different motherboards. However, before purchasing a RAM upgrade, it is important to make sure it is compatible with your motherboard. On Crucial’s website there is a tool on the homepage that will help you find the right upgrade for you. You can search by manufacturer or let the program scan your computer. Both options are quick and will help you find the correct RAM.
The DDR3, 1600 RAM from Crucial was not as fast as some of the other products. The latency figure measures how quickly data can be accessed on a given location on the RAM. Latency is measured in clock cycles. The lower the number, the faster the RAM can access the data. The Crucial product is slightly slower than other similar devices, but only those that are overclocking and benchmarking would be able to tell any difference. The Crucial RAM upgrade is still very fast and will help speed up your computer significantly.
The Crucial upgrade has a voltage of 1.6 volts, which is standard measurement for all the devices we reviewed. Again, the lower the voltage helps the computer move faster. This measurement is how much power is used by the module.
The actual speed measurement of the module is DDR3-1600, PC3-12800. This measures the bandwidth available with the RAM. The DDR3-1600 stands for the data transfer rate. This number is measured in megatransfers per second (MT/s). A megatransfer is one million data transfers per second. The PC3-12800 measurement refers to theoretical bandwidth measurements. The bandwidth is calculated by taking the speed (1600) and multiplying it by eight. This is done because the modules transfer data one byte at a time and there are 8 bits per byte.
The double data rate three (DDR3) and synchronous dynamic random access memory (SDRAM) is the latest and greatest in storing data for computers or other devices. Not all computers use DDR3, many still use DDR2 and the two are not compatible. DDR3 modules use less power and have a higher bandwidth than DDR2. One other thing to keep in mind is that latencies are measured differently for DDR3 and DDR2 devices. DDR3s have a higher because the clock cycles are shorter.
We reviewed products that all have the same capacity. This is not to say that these computer memory upgrades are perfect fits for everyone. We recommend going to the manufacturer???s website to find the computer memory upgrade that works best for your needs. However, the products we reviewed all had very similar capacities.
The upgrade we made was to add a dual-channel 4 GB RAM module. This means there are two sticks of RAM that both have 2 GB of memory. Dual channel doubles the data input by putting the two modules side by side. The two modules do not have to be the same speed and size, but the motherboard will run at the speed of the slowest one installed. To speed up your computer, make sure the two RAM modules match and have a high speed with a low latency.
The modules we reviewed are all non-error correcting code (non-ECC), also known as non-parity. ECC or parity modules find errors in servers and are usually used in large networks. Some personal computers use the parity modules but the RAM is more expensive, and so is the motherboard that is ECC compatible.
We also stuck with dual in-line memory modules (DIMM). These modules are quickly replacing the single in-line memory modules (SIMM). The main difference on the DIMM is that there are separate contacts on either side of the module. SIMMs also use a 64-bit data setup where DIMMs had a 32-bit path.
The Crucial device we reviewed has a heat spreader. Because the heat generated by constant use of the RAM can damage the device, there is a cover, usually aluminum or brass, which will absorb the heat.
The RAM modules we reviewed are also unbuffered. This RAM is used by personal computers, not networks or servers. With unbuffered products, the data is accessed directly. Buffered RAM stores the data in caches to be accessed at a later time. Data is more swiftly accessed with unbuffered devices.
Help & Support
The support options offered by Crucial are by far the best of all the products we reviewed. Whether you are shopping for RAM or installing a product you already purchased, Crucial has an option to help.
We strongly recommend using the live chat option when you have a question. We tested this option on a variety of occasions and found the response time to be minimal and the representatives to be knowledgeable. We also tried calling the support line and we were connected instantly to friendly customer service representatives who helped solve all the problems we came across.
On top of all the fantastic customer support options, Crucial is actually the only product we reviewed that comes directly from the RAM manufacturer. There are only a handful of RAM manufacturers in the world. Most distributors of computer memory upgrades purchase the RAM from manufacturers such as Hyundai, Micron and Samsung. However, Micron distributes its entire consumer branded RAM selection through Crucial. Because RAM upgrades are all so similar, it is important to find a manufacturer and distributor you can trust, and we trust Crucial.
The Crucial computer memory upgrade is the most comprehensive, reliable product we reviewed. The speed is among the best and the help options are outstanding. Whether you are a computer novice or expert, you are sure to find a suitable RAM upgrade with Crucial.
