54398	2002-06-14 09:55:00	Is it possible to overclock a Pentium 3 800MHz Coppermine CPU? I have searched the net and have had no joy. Everything I have read seems to say that Intel locked the Multiplier at it's set rate. There is nothing in the BIOS that lets you change this setting. The only thing I can find in the motherboard that might resemble the multiplier is 'Ratio of Processor Core to System Bus Frequency' Is this what I am looking for? I changed the jumpers from 6 to 8 But this made no difference to speed. I have since changed this setting back for safety. Any help would be much appreciated. It is not my machine I am doing it for a friend, and they don't care if I stuff the machine, all the same I would like to know how to do it before I go and start aimlessly changing settings :)	Guest (0)

Next step will be 6.5, giving 866 Mhz which would be outside the likelihood of safe overclocking anyway. Having said that I think some PIII chips are multiplier locked (or it may occur as a Motherboard function?) If you could then it may screw up other peripherals? Gain would barely be noticeable as well.	Guest (0)

54401	2002-06-14 11:09:00	'Gain would barely be noticeable as well' DOUBT IT ;-) p3's are multiplyer locked so you can only overclock with the fsb. the 800mhz came in two flavors. the 8x100 and 6x133 ver. how far you can overclock depends on the chipset you have(motherboard). don't forget (depending on motherboar) you can lower the multiplyer and increase the fsb if the total mhz gets to be to high.

54402	2002-06-14 11:33:00	There is a way to do the overclocking, without altering Motherboard jumpers. Get a NVIDIA GeForce MX/MX 400 AGP Graphics card to replace your existing graphics card. I use a 64MB memory card as above. It arrives with 'Winfox' software, which icon resides in the system Tray. Left click on the icon, select 'Advanced Tools' and increase your CPU & Graphics speeds.... Try it a bit at a time, though. If you increase too much your system may become unstable. Cheers.	Guest (0)
54403	2002-06-14 11:53:00	sorry but no. thats only overclocking the video card. winfox comes with the leadtek cards but a lot of others come with their own overclocking/tweaking software. or you can just enable nvida's 'coolbits'.	Guest (0)
