noob question - agp and pci locks

el_brato · 24 Feb 2006 at 09:51

hi everyone - okay i'm intending on breathing a little more life into my xp2400 before eventually upgrading. I have read the overclocking guide and can change the fsb and multiplier within the bios. However, before doing this the guide states:
"Firstly, you need to set AGP & PCI locks to on or AGP=66mhz and PCI=33mhz"
Yet i cannot find where these settings are! and if i try and lower the multiplier and increase fsb at the moment a small increase from 133 to 138 requires a CMOS reset - so i assume something is not right.
Thanks in advance

system:
athlon xp2400+ cooled by delta fan so temp not a problem
1gb geil value
9800 pro with arctic cooling
MSI KT4AV7 mb

If you can't find a setting for it in your bios then there's a good chance you can't lock it

Might be worth trying a google for it and see if anyone else has tried.

Your mobo has a VIA chipset that does not have AGP/PCI locks but it might have a 200Mhz divider that kicks in at FSB speeds above 200Mhz but if it doesn't have that you could mess up your harddisk due to a too high PCI speed.

Also ATI cards hate higher AGP speed so you might get instability very quickly.

mmmmmmmm - thanks for the help guys -
risk of needing a new hdd or going for 200mhz fsb is the question! Think i will burn everything off my hard disk and give it a go.

Are you suggesting for example putting the multiplier down to 10 and fsb to 200 to test this?

Anyone else tried this or can give me further advice

I would try 10x201Mhz (do not try 200 as it might kick in at >200Mhz, if you get missing files or BSOD stop straight away.

But before you do, make sure you have PC3200 memory, if not you have to run the memory at a divider.
