    Question:How to fine tune IOQD,following this tip after running sandra.
    PC running on WinXP PRO with Pentium3_800Mz,VIA APOLLO chip set,

    Thanks in advance for any help you may provide.
    Warning W231 - The IOQD (Host Bus In-Order Queue Depth) is set too low, most likely 1, i.e. no queue. This indicates the depth of the host bus pipelining; thus 1 indicates that no pipelining is to be done on the bus. This reduces the performance of the host bus which is crucial to performance. P6 (Pentium Pro, II, III, Celeron) has an IOQD depth of 8 while the P4 has an IOQD of 12. Most chipsets have an IOQD of 4 or more.

    Fix: Check that BIOS settings were not reset or set to Fail-Safe defaults. Reset them to Optimised or Normal

    Hello wah fkir,

    IOQD is the same as In-Order Queue Depth. Click here to check out the details.
