Higher multiplier not detected

PLEASE HELP!

On my mainboard I can set a multiplier higher than the CPU's default,
yet, the CPU will not run faster. What can I do?

I have an Asus A7V266 board with an Athlon XP 2400+ CPU (@ 133x15).

When I up the multiplier in the BIOS, e.g. to run at 133x16, the CPU
still runs at 133x15 (checked with WCPUID).

Setting the multiplier to 14 on the other hand, DOES work.

Anyone any idea what is happening? How can I solve this?

Kind regards,
Bart

The board is set to support XP (lower voltage, higher mulipliers),
so I *do* get the higher numbers in the bios,
i can even set and save them
(which cannot be done if a CPU is locked).

Yet, the CPU will not 'recognize' a higher multiplier
than its default value of 15.

So, a BIOS setting of 17x133 results in 2000 MHz... (15x133...)

Anyone any clue? Please?

There are jumpers on yhe board that have to be adjusted to achieve the
higher multipliers.

Well, I can tell you the problem. Your board dosesn't properly support the
5th multiplier bit. What's the best workaround with your board? I don't
know. But it will sure help if understand how the multipliers work. Only
one thing is for sure. It can be made to work at different multipliers.
Might try setting the multipliers to different settings on the board
itself. See Multiplier Cross ref. in link below to determine how they
translate on boards that only support 4 multiplier bits.

Wes, John,

Thank you for your replies. The A7V266 officially supports multipliers
up to 24. The board has a jumpersetting: you can choose bewteen the
lower numbers (3 to 12,5) and the higher numbers (13 to 24).

I do can try the lower number region and see if the mobo correctly
"translates" 9 into 17. I'll keep you posted of my progress.

Just a thought: could the board or the CPU be defective?

Sounds like a novel problem, so bear with the "thinking out loud
comments", not trying to be cute.
Locked cpu/open L1s for example should have nothing to do with bios
setting operation. But we are surprised that your "266" mobo has such
high multiplier options as 17X. Is it at all possible that bios
Multiplier option could be in "Auto" mode (not User-defined) and still
allow you to manipulate "the numbers"?? That would explain...(except
positive 14X result).

Which means the default LO-LO-LO-HI-HI 15X signals are not being
changed to
LO-LO-HI-HI-HI 17X signals, but do change to LO-HI-HI-LO-HI 14X
signals when so set in bios...this "is" very strange". Try setting 8X
in bios and see if you get 16X or 8X...just a "hunch"...if 16X then 9X
might get 17x.

Most PC133 will work at 143, why not try 143x15=2145? That will just about
max out what you're system is probably capable of.

Did you look for a BIOS upgrade?
