Advice 1: How to determine frequency of RAM

Memory computer has its own volume and frequency (speed) of work that determine the performance of the operating system. The higher these numbers, the better the system will work. If RAM memory is known to many users, the frequency of operation is not known to all. Meanwhile, you can find it quite simple.
How to determine frequency of RAM
You will need
  • Computer, memory, screwdriver, CPU-Z, Internet access.
The fastest way to know the frequency of the operational memory, without resorting to the use of various programs, is to look at the module memory. To do this, remove the system cover by unscrewing the two fixing screws on the rear panel of the computer case. On some chassis cover can be secured with latches. On the motherboard find DDR inscription. There will be ports for modules of memory. Remove one of the modules of memory. To do this, simply push down the latches on both sides on the port.
Now look on the memory the inscription DDR. The frequency of the memory will be written next. For example, DDR-400 MHz or DDR2-800 MHz. The figure at the end of the row is the index of the frequency operational memory. Please note that some modules memory , you can find row PC, and then numbers, for example, PC2-6400. Each value PC meets the definition of an operational frequency of the memory. For example, PC2-6400 so that the RAM runs at 800 MHz. If you have a module of memory inscription PC, find the Internet a table of the characteristics of the operational memory. In this table, just see what frequency the memory matches your PC.
If you don't want to open the system cover, can use the program CPU-Z. you can find this utility for free. Install the software on your computer and then run it. After the first run the program takes a few seconds to gather information about the system. When you get to the main menu, select the Memory tab. Then find the line Dram frequency. The figure opposite is a frequency of the operational memory. At the top of the program window provides information about the type of operational memory.
Remove the cover of the system unit only when the power is off the computer!

Advice 2 : How to determine the type of RAM

Sometimes user is required to determine the type of operational memory, which is located in his computer or lying in front of him, i.e. to define on external appearance. This can be done using simple analysis.
How to determine the type of RAM
You will need
  • Strap memory.
At the moment there are several types of memorythat is actively used in the Assembly of computers to this day: DDR3, DDR2, DDR DIMM and SIMM. You should make a reservation that the last 2 types of memory used in the system blocks until now, but such rarities have not to buy.
SIMM. Strap this type of memory is designed for 30 contact. Scope — computers with processors 286, 386 and 486. There is also a kind - SIMM 72 contact, which was set to the 486 processor series and Pentium-I.
DIMM. This type of memory is merely another name for the type of SDRAM. DIMMs have become the basis for Intel Pentium and was actively manufactured until 2001. If SIMM has only a single groove, like other modern motherboards, the DIMM contains 2 grooves on the contact track. This is the only significant difference in appearance.
DDR SDRAM came after and became his follower. First appearance dated 2001. The novelty of this type of memory was to double the data transfer for one clock cycle. In external appearance it becomes clear that with the emergence of new models of strips of memory, the number of contacts significantly increased. For DDRmemory , this value is 184.
DDR2 is an improved version of DDR. The key difference is double the increase in the speed of data transmission for one clock cycle. When inspecting memory DDR2 note the strip of contacts, their number is 240.
DDR3. Externally, this model would be difficult to distinguish from the model of the last series is related to the similarity of the contact position. However, the same number of contacts does not make their electronic counterparts. The only sign by which to distinguish one memory from another — direction grooves to the contact line. If the fillet looks at the chip, this plank contains DDR3 otherwise DDR2.
