DFI Lan Party: Resetting the battery / OC Problem

[ijesse]

From Anandtech review of the DFI Lan Party 875 Pro MB:
"The only downside about FSB overclocking with the PRO875 is that recovering from too high a FSB value isn?t all that good. Clearing the CMOS via jumper doesn?t do the trick; you must uninstall and reinstall battery as well."

I ran into this trouble today when I was trying to OC my new system. After taking out the battery (the big round one), putting it back in, and then resetting the CMOS, I am able to run my computer again as normal except for one really strange problem: When I try to bump up the FSB in the BIOS, and then save and restart, the computer still goes back to the default 200mhz. IS there a certain order I must clear the CMOS and remove the battery? Is there another battery I'm missing? What am I doing wrong?!

System:
DFI "Lan Party" 875Pro
2.6c P4
2x 512 Corsair XMS
Radeon 9800
160 GB SATA
Pioneer 4X DVD-RW

Thanks for your help!

I also just tried it with a 2.4b and have the same problem- when I bump up the FSB from 133 to 135 for example, then save and restart, it boots at 133 again, while saving all other BIOS settings.
