A lot of people don’t know about these settings. Even the average person doesn’t know about these settings. Even though they aren’t very important, they still play a role in how quickly and quickly your memory works. If you are building a very powerful PC, you will also need to compare them. Memory delay times, or how long it takes for one thing to happen before another, are called “memory hours.”
CAS: The amount of RAM highlighted in the picture. The first number indicates the CAS, which is the most important at different times. The CAS column stands for Address Select, indicating the time it takes for the memory to respond to a request for information. The numbers you see printed on memory do not indicate the time in milliseconds, they are actually cycles, which means less CAS is better. However, we do know that memories all move at different speeds and if we want to know how much we need to take care of them in nanoseconds. The formula is as follows: (CAS Latency / Memory Frequency) x2000. So slow RAM, for example, may have some delay benefits, but in general everyday use, the frequency will play a big role.
tRCD: is the second number reported on timings, I write it as you see it mentioned in your mainboard BIOS. To explain what this means, it is necessary to first form a basis: RAM is distributed like a grid, imagine an excel sheet, and a special row before the PC finds this column. Should have access to which contains the information required by the system. The acronym for TRCD may be a somewhat approximate translation of “delay between row and column” and in fact, time indicates a delay between accessing the row and finding the column containing the information.
TRP: Number three indicates a delay in opening a new line, this is the time that passes between reading one line and another line.
TRAS: The last number indicates the minimum time, in cycles, in which a line must be “open” to allow the information to be read correctly. It explains why this is the most expensive time.
XMP and AMP. Both the speed and timing of RAM have to be set manually in the mainboard BIOS, not to mention that the Mainboard automatically recognizes them with the RAM memory’s SPD chip. If you have XMP (Xtreme memory profile technology developed by Intel) or AMP (AMD memory profile) profiles in your RAM by enabling XMP or AMD entry in the motherboard BIOS, then all RAM parameters are automatically manufactured by the manufacturer. Will be configured as provided. . If they are not in your memory, you should check them manually. If the mainboard sets the parameters worse than expected, your performance will be less than if you can set everything correctly. If, on the other hand, the mainboard sets better parameters than this, you may experience instability in the system. This is rare, but if you have blue screens at the end of the assembly, it may be helpful to keep this in mind.
Dual channel and quad channel
Just talking about frequency, we have seen the term dual channel. This technology was developed in 2003 to reduce the barrier between CPU and RAM, which basically allows to double the bandwidth between RAM and CPU, further distributing between motherboard channels. To install RAM modules, which are then simultaneously queried. For this reason, it is commonly used on most performing computers to divide the amount of RAM between at least 2 modules, for example by installing 8 GB of RAM. Prefer 2 4 byte modules. To avoid problems in the system, the memory channels must be identical to each other.
In addition to dual channels, there are also triple and quad channels. The Triple Channel was actually a top-notch development on the Intel LGA1366 socket and is no longer used, actually replacing the Quad Channel on the highest performing Intel and AMD systems, while the more classic Intel and AMD designers on PCs. Prefer to have dual-channel format.
It is important to keep the following in mind: RAM manufacturers sell their modules in kits to ensure their dual channel operation. If you combine separately purchased cabinets, even if they are identical to each other, the manufacturer does not guarantee that they will work properly in a multi-channel system. This does not mean that you will definitely get in trouble, but that if you upgrade by adding RAM module and do not take your place in the price of a new kit, then it is good. You have to test to make sure everything is working properly. Stable way ..
Why does Ram die so quickly?
Under perfect conditions, RAM has a long lifespan. The same 2016 HardWare.fr study found an incredibly low incidence of RAM return, down 0.20% for Kingston and 1.08% for Corsair. Given the astonishing amount of RAM used worldwide, this figure is extremely low.
But two things can eliminate a working RAM module in the blink of an eye: an increase in temperature and power.
Most RAM modules have an operating temperature between 0 and 85 degrees Celsius. If you go beyond these temperature limits, you can damage your RAM. It won’t happen immediately, and it would be ridiculous to suggest otherwise. But prolonged exposure to “extreme” temperatures shortens the life of your RAM.
Power outages from faulty motherboards, faulty power supplies, and electrical spikes can also cause failure.
How long does RAM last?
In a typical PC or laptop, RAM lasts a long time, usually for at least 10 years, if not 20, then most of the time RAM will be the last piece of hardware, which is more than all other hardware. Performs better. Bought with it.
So, let’s make a summary. Before buying your RAM, identify the following well to buy the right module for you:
- Module version (DDR2.DDR3, DDR4)
- Fixed or for notebook (Dimm or So-Dimm)
- Check if you have trouble with high profile memory.
- Possibly buy a kit to take advantage of all the RAM channels (double channel, quad channel) on your main board.
- Choose technical features, such as speed and time, to suit your performance or value for money.
When assembling, pay attention to how you handle the RAM, test it after adding some RAM to your system.
