      How to Test Memory

      When something begins to go wrong with a computer and things start acting differently than they should, the first thing to test should be the computer’s memory. Problems, even small ones, in the computer’s memory can lead to very erratic behavior from the computer, even causing it to crash. Memory Testing Software Memtest86 is our

    • CAS Latency

      CAS Latency

      CAS latency is short for Column Address Strobe latency. CAS latency is the time (in clock cycles) required to access a column of memory on a DRAM memory module. A CAS3 rated memory module requires 3 clock cycles to address a column of memory, where a CAS2 rated memory module can accomplish the same task

    • DRAM (Dynamic Random Access Memory)

      DRAM (Dynamic Random Access Memory)

      DRAM is Dynamic Random Access Memory. DRAM is the most common form of RAM. When someone says that a computer has "one gigabyte of RAM", what they really mean is that the computer has one gigabyte of DRAM. DRAM is called dynamic because it must constantly be refreshed or it will lose the data which

    • What is a Hypervisor?

      What is a Hypervisor?

      A hypervisor is a virtualization technique that runs multiple operating systems on the device. While non-hypervisor virtualization techniques run multiple operating systems on domestic computers and hand-held devices, hypervisors are used exclusively on devices whose sole task is to run multiple guest operating systems for commercial or industrial purposes. Hypervisors are used in gaming technologies,

    • CMOS RAM

      CMOS RAM

      When the computer boots up, certain amounts of information are needed to ensure that the computer boots properly. This includes hard disk types, keyboard and display type, chip set and the time and data. For example, the hard drive booting properly means that the operating system boots properly. This is important to understand because it

    • NVRAM (Non-Volatile Random Access Memory)

      NVRAM (Non-Volatile Random Access Memory)

      NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from

    • DIMM (Dual In-line Memory Module)

      DIMM (Dual In-line Memory Module)

      Dual Inline Memory Module or DIMM is a series of Random Access Memory (RAM) chips mounted on a small printed circuit board. The entire circuit collectively forms a memory module. DIMMs are commonly used in personal computers, servers, and high-end workstations. The DIMM makes physical contact with the computer’s data bus through teeth like connectors

    • SDHC (Secure Digital High Capacity)

      SDHC (Secure Digital High Capacity)

      SDHC stands for Secure Digital High Capacity. It is a format for new memory cards that is based on the 2.00 specification of the SDA (Secure Digital Association).The name Secure Digital is due to their ability to protect copyright, using digital copyright management. This has made these memory cards a favorite choice in the audiovisual

    • ECC Memory

      ECC Memory

      ECC (Error Correction Codes) is a method used to detect and correct errors introduced during data storage or transmission. Certain kinds of RAM chips inside a computer implement this technique to correct data errors and are known as ECC Memory. ECC Memory chips are predominantly used in servers rather than in client computers. Memory errors

    • Firmware

      Firmware

      We all use electronic devices, whether they are mobile phones, computer routers, MP3 players, cable boxes, etc. These electronic devices include hardware, the physical electronic components and software, programs that help these components run effectively. Firmware is a mix of both. Firmware Firmware is usually defined as a type of program that runs within an
