    Just did a quick test and I've figured it out... You're indeed correct (I've not bothered wth the HPET stuff yet).

    Ran three benches quick and I was able to extrapolate what happened.
    Boot speed: 3400. Software adjusted speed: 3800.
    3400/3800=.8947etcetc
    Memory Bandwidth at software-3800 CPU, 3200 DRAM = 53,686mb/s
    Memory Bandwidth at BIOS 3800 CPU, 3200 DRAM = 49,317mb/s
    Difference: .9155

    CPU Queen at Software CPU: 98822
    CPU Queen at BIOS CPU: 88380
    Difference: .8943

    CPU AES at Software CPU: 75230
    CPU AES at BIOS CPU: 67295
    Difference: .8945

    There was a slight difference in my memory timings between the runs, but not much. Enough that factored in with margin of error I think makes up for the variance. Otherwise, I'm sure if I ran all the other AIDA tests and ran the numbers, they'd all come out to being the same of only 10-thousands off from what the Clock difference is.

    Shame, I was really hoping I had come to some magical configuration T_T Yet now my configuration seems to be sub-par heh
    Oh well. Back to the drawing board

    UPDATE: More of notes, really...
    Turned off HPET in BIOS (not changed the Windows BCD option yet), which of note, on the Titanium is a hidden setting now.
    Left CPU Multi at 38x
    Noticed that due to changing it originally, it set the (also hidden) CPU Features option of Cool'n'Quiet to DISABLED... so I set it to ENABLED.
    In Windows, I fired up CPU-Z, noticed my CPU clock was a 3500. Odd. Set Power Plan to Balanced and Turbo kicked in, odder still. Seems their hidden C'n'Q option overrides any set Multi.

    Output the CPU-Z report since the Timers are listed there (though I had hoped to find that nifty stand-alone program that Christian used in his old Windows 8 RTC article).
    As booted, with HPET off (BIOS) and "38x" + C'n'Q
    on High Perf plan @ 3500MHz: ACPI: 3.58MHz, Perf: 3.58MHz, Sys 1KHz.
    on Bal plan (Boost)@ 3900MHz: ACPI: 3.58MHz, Perf: 3.58MHz, Sys 1KHz.
    Using K17TK and set FID to 38 (same Windows session as above):
    on EITHER plan @ 3800MHz: ACPI: 3.58MHz, Perf: 3.58MHz, Sys 1KHz.

    (CPUz was reopened before exporting each Report, so I'd imagine that these numbers aren't lingering in between runs; however, I can't say for certain)

    AIDA bench results coincide with the numbers put out with HPET ON and FID changed in Windows.
    I'll need to re-test CPU-Z's report of Timers with HPET turned back on in BIOS...

    If anyone has a link to that "Timers" program by the CPUID guy, that'd be helpful
