OC to 800MHz and screen res changes

[FastEd]

My new 533 FC OC's great on my ABIT BM6, but sometimes it changes the screen res to huge. Only seems to do it above 100MHz FSB. I have a ATI 128 16MB card. Anybody know whats going on? Thanks in advance for any help!

Try 105 mhz bus. Your board might not be doing 1/3 pci divider yet so it is going nuts on 50 mhz pci bus

Are you suggesting that coconuts migrate?

OK- I'll check. I was sure I had 1/3PCI & 2/3 AGP

Nope- that wasn't it. Still does it. running now at 75MHz FSB and it's perfect. I sure would like to run it at 800+
