cpu misread?

Gordon J. Rattray

Hi there,

I've got an Asus P4S8X-MX motherboard with a 2.4 Ghz P4 CPU in it.

The bios and Windows picks it up as being type 2.4 Ghz and speed as 1600
Mhz.

Why is there a difference? I would have thought the speed would be matching
at 2400 Mhz as that's what it is.....

The bios is the latest, and no overclocking set up in the machine at all....

Any ideas why this machine, and CPU, is running slower than it should be?

Thanks,

Gordon

Enter the BIOS (use "Delete" key at power up).

In Advanced:JumperFree Configuration -->

Set "AI Overclock Tuner" to [Manual]

A new setting should appear, CPU Frequency.

Set "CPU Frequency" to 200MHz. (Right now, it is running at
133MHz, and that is why the core is at 1600 instead of 2400.)

For safety, you can set "AGP/PCI" to [66.6/33.3]
(If you use clock values other than 133MHZ or 200MHz for
the CPU Frequency, such as an intermediate value, then it
becomes more important to lock the AGP/PCI to 66.6 and 33.3
respectively. 66.6 and 33.3 are the normal values.)

I wouldn't bother adjusting the DDR memory frequency, until
you've had a chance to boot into Windows and use a program
like CPUZ ( www.cpuid.com ) to verify what the motherboard
is doing with the memory frequency.

Since this is in many ways like overclocking, if I was doing
this with my computer, on the first reboot I would run
memtest86+ ( www.memtest.org ) as a means of seeing if the
new settings are stable. If, for any reason, there is a
problem with the new settings, you would not want to corrupt
your hard drive because of it. Using a floppy or a CD with the
memtest86+ program loaded on it, gives you a chance to verify
that the computer works OK, without having to use your hard
drive to prove it.

Another way to prove stability, is to download a Knoppix or a
Ubuntu Live CD. The download is 700MB (knopper.net or ubuntu.com)
and for people on dialup networking, that is a lot to expect. If
you are on broadband, it takes maybe an hour to download, depending
on the mirror server you use. Either Knoppix or Ubuntu Live CD's
don't need a hard drive to work either, so those Linux operating
systems are another way to prove the computer is stable at the
new settings.

Bang On, Paul! That's what did it.....now it's running at what it should
be....

Many thanks,

Gordon

It appears this is a new build you have with possibly a Core2 DUO processor , don't
know - can't say, you haven't provided much info.
The 1600Mhz is the SideBus which = 800Mhz per core.

That's so wrong I don't even know where to begin telling you why you're
wrong.

You've _GOT_ to be kidding this guy right? He's a personal friend and you've
got some kind of bet on what sort of inane replies you can give to his
questions, right?

wow. just wow.

Truly, I believe you don't know where to begin, I won't question you on that.

This guy? Personal friend? Yeah right! If you know how wrong I am, what's
keeping you from rectifying the question put forth? Perhaps you've got some kind of
bet on what sort of inane replies you can give.

Nah, I'm just busy having fun marvelling at how much the MVP program has
gone downhill lately. Seems they'll let anyone in these days.
