SPD Question

    On an Abit BF6 (or in general), do memory settings in the system bios
    (CAS2 or 3, etc) override what's programmed on a dimm's SPD chip?
    How about if the SPD chip is gone altogether?

    I got a good deal on two Infineon 256MB PC133 CL3 SDRAMs,
    which has no problems running at CL2 at 133MHz. One of the dimms
    gave a "Warning - SPD not found" error during boot. On closer
    inspection I discovered the SPD chip was skewed upwards (probably
    due to improper insertion) and when I tried to realign it, it popped off.
    The dimm works perfectly otherwise and I'm wondering if it's still
    running at system bios settings (CL2) or will the system bios revert it
    to conservative defaults (CL3)?

    Will SiSandra, Aida32 etc tell me whether the memory is running at
    CL2 or CL3?

    Thanks a lot,

    Thanks Jens. It's good quality memory (HYB39S128800CT-7.5 chips)
    and reviews claim the dimms should run fine at 133MHz CL2. Still, I
    will run memtest86.
