Why should the CPU-Z report my memory's DRAM Frequency as 333.3? The JEDEC #1 is 333.3, and #2 is 400. But I don't understand this. The "Max Bandwidth" section says: PC2-6400 (400 MHz)

I had got a single stick of 2mB of RAM installed that should have been of 800 mhz. Is this the case? Because I had thought that 800 x 2mB would become 1600 mhz! Earlier I had 667 MHz.

  1. Can you post a screen shot of what you are talking about?

    Also, have you went into your BIOS and adjusted the memory settings to match what is on the RAM (voltage, timings and speed)??
  2. Here is the info on the "Memory" tab:


    Type: DDR2
    Size: 2048 MBytes
    Channels #: Single
    DC Mode: empty
    NB Frequency: empty
    DRAM Frequency: 333.3 MHz
    FSB : DRAM: 4:5
    CAS# Latency (CL): 5.0 clocks
    RAS# to CAS# Delay (tRCD): 5 clocks
    RAS# Precharge (tRP): 5 clocks
    Cycle Time (tRAS): 15 clocks
    Bank Cycle Time (tRC): 21 clocks

    [The last four rows "Command Rate (CR)", "DRAM Idle Timer", "Total CAS# tRDRAM)", and "Row To Column (tRCD)", are empty.]
