AGP/PCI lock

I'd really like to push my overclock to the max, but I just read that not having the AGP/PCI buses locked at 66/33 mhz can cause data corruption.

If there is no setting to manually lock the PCI/AGP buses in the BIOS, am I SOL as far as overclocking goes?

If I do overclock without these bus speeds locked, what are the possible conflicts it can cause?
 
You might be able to get a very mild overclock without harming the rest of your system, but in general, you shouldn't overclock if you can't lock those down to 66/33. The harmful results that may occur wouldn't be worth it IMO.
 
What board/chipset do you have?

I had an old epox 8KHA+ that I overclocked my 1700+ tbred CPU to 1.68GHz with, the PCI was running at about 38MHz and really hated me if I went any further but right there it worked fine. YMMV though.
 
Which motherboard & what cpu? You may mod the cpu to boot at higher FSB w/o affecting the bus speed.
 
your the guy with the Asus mobo A8V Deluxe. i wrote my review in the other column you wrote, sorry bud but this board has a VIA chipset. see the other post you wrote. believe i tried and corrupted my hard drive at 220 so i am surprised you got up too 230. but back her down before its too late and you loose everything.

To whom are you replying?
 
He was replying to me. I had asked the same question in another topic, but I thought the thread was pretty much dead so I started this one. 🙂

And ya know... now that I think of it, it did have to chkdsk to fix some stuff, but I thought that was because it locked up while windows was loading. Heh, guess I'll stay at 2.2ghz for a while.
 
It depends on which revision of that board you have. The revision 2.00 boards supported async bus frequencies. The revision is printed prominently on the board itself. I used to have one of those at one point and got about 270 out of it, but that's pretty much the limit of the chipset.
 
I actually damaged an SATA hard drive by overclocking the pci bus too far. My PATA drives were all fine though.
