  • Administration

    • Welcome! Please Sign In.

    • What the SIG is…and is not.

      • Is – an information resource for computer users and potential computer users

      • Is NOT – a way to get your computer built or repaired (contact the GSBUG Daytime Hardware SIG)

    • Log – Random Access/Q&A (First Come…)

  • Administration (continued):

    • Presentation materials will be posted at:

GSBUG Hardware Info SIG

  • System RAM: 2003 Update

    • “System RAM” – the off-processor (off-processor- module), random access memory (RAM) used to store instructions and data.

    • “DRAM” – dynamic RAM (only retains data when power is applied/refreshed)

    • Primary types:

      • SDRAM (synchronous DRAM)

      • RDRAM (Rambus DRAM) or DRDRAM (Direct Rambus DRAM)


Gsbug hardware info sig5

GSBUG Hardware Info SIG

  • System RAM: 2003 Update (continued)

    • CAS Latency (CL) – definition per Crucial Technology (division of Micron):

      • “The amount of time in nanoseconds (often measured in clock cycles) between a request to read the memory, and when it is actually output. SDRAMs are typically referred to as CL 2 or CL 3, with CL 2 parts being faster.”

      • Today, frequently also CL 2.5

    • Unbuffered vs Registered vs Registered ECC – consult your motherboard manual for what you need. For the curious, see http://www.crucial.com/library/glossary.asp


Gsbug hardware info sig6

GSBUG Hardware Info SIG

  • System RAM: 2003 Update (continued)

  • System RAM: 2003 Update (continued)

    • RDRAM (continued)

      • Compatible chipsets – currently only Intel 850, 850E and 860, SiS R658 (SiS R659 announced)

      • Installed in pairs (dual channel)

      • NOW priced at roughly 2x the cost of quality DDR400

      • Performance – depending on the configuration and application, may be faster than other forms of DRAM


Gsbug hardware info sig10

GSBUG Hardware Info SIG

  • System RAM: 2003 Update (continued)

    • Memory bandwidth:

      pipe width (in bytes) x speed (in MHz) x

      number of channels =

      memory bandwidth (in GB/sec)

      “speed” is “effective speed”; e.g., 100MHz SDR, 200MHz DDR (both on a 100MHz clock)

    • Example:

      PC2100 DDR SDRAM

      8 bytes x 266MHz (133MHz DDR) x 1 channel

      = 2128MB/sec (2.1GB/sec)
