I have a MSI MS-6368 mobo that I've installed a 566 celeron in.

Is that a coppermine celly?


However, the only options in the BIOS (Award V.6) are to increase FSB
to 68/34 or 75/37. How can I get this sucker to 100Mhz FSB?

By jumper perhaps? However, if it isn't a coppermine and there is no
facility for raising the vcore then you have no chance.


This is a fairly new BIOS (dated last summer), but I'm disappointed
in its overclocking options.

Anyone have any suggestions??

A lot depends on what revision your mobo is. That board came out in

several

different flavours ranging from 1.0 revision through to 5.x and they vary
considerably in what they are capable of.


It's version 5.


Ok, just done some home-work, it has to be a coppermine celly as the board
doesn't support earlier CPUs. MSI state that the board supports a FSB of
66/100/133 so I'm assuming it'll be by jumper. If you don't have the

manual

and want to download it go he

No jumpers available. Only jumpers on the board are for clearing CMOS and
enabling front audio ports.

In the BIOS, under Frequency/Voltage control, there are three options:
1. Autodetect DIMM/PCI clock (enabled or disabled)
2. Spread Spectrum (enabled or disabled)
3. CPU Host / PCI clock (default, 66/33, 68/34, 75/37)

MSI says it automatically detects CPU clock (which is 66Mhz).... maybe
that's why it isn't letting me go to 100Mhz FSB? Maybe MSI's allowed
overclock is limited to 14% or something weird like that....

This seems to be a common 'feature' of some BIOS versions. For some reason
they get it into their head no one would want to encroach on the next
legitimate FSB so the only options they allow are 'up to' the next
'automatic' setting. In your case, whatever FSB choices they have available
up to 100 MHz FSB, since that's the next 'legitimate' one.

My chaintechs do the same thing but, as irritating as it is, they at least
have the FSB jumpers to over-ride the CPU.


Would raising the vCore change what MSI sees as the CPU clock or allows for
overclocking? I can raise it to 1.75v by wrapping a coupla pins on the
processor.

Changing Vcore isn't going to make it 'think' it's a different processor.
The BSel pins on the processor tell the motherboard what FSB to run at and
that's what it will run at unless the BIOS has some option to over-ride it.

What you need to do is isolate the Bsel0 pin (AJ33) so it goes high and
tells the motherboard it wants 100 MHz FSB.


Right now, I have it running at 8.5x75 for 638Mhz. I understand most folks
are running these at 8.5x100 for 850Mhz. I'd like to know how to get it
to run at 100Mhz with this MSI mobo.... maybe time for an email to MSI
(doubt they'll help, though).
