what is the speed of your RAM? PC133 requires 7.5ns at least, I don't know
there is any pc100 7.5ns RAM. your RAM should be rated 8ns, which should not
run at 133, even I have seen report that high quality 8ns RAM can operate at
133, my opinion is do not try your luck as overclock RAM may result system
corruption.

Run your system at 112 is offensive to any PCI card, since PCI card has to
run at 37mhz, which is beyond PCI spec, most PCI cards can operate at this
speed without any problem, but if you have any SCSI or IDE controller card,
it is highly recommended that never overclock the PCI bus.

Subject: [PCBUILD] Overclocking PC100 SDRAMS


I recently replaced my PII 350 100MHz CPU with an Intel PIII 533B 133MHz
CPU.  My motherboard is a Tekram P6B40-A4X v1.04.  This Tekram board has the
ability to to extend the bus clock from 100MHz to 103, 112, or 133.3 MHz
"for internal test only."  If the clock speed is raised to 133.3MHz would
the other components be damaged or have the operating life drastically
shortened?  The video card is an ATI Xpert at Play 8Mb AGP w/TV out.  The
two SDRAMS are PC100 64M and 128M.  I ran at 112 MHz for about 8 hours with
no sign of instability or error detected.  I would like to go to 133 MHz if
possible without buying PC133 SDRAMS.  If that is not possible, would
continued operation at 112MHz be acceptable?
