PocketMatrix

Well, I've been attempting to overclock my new iPaq hx2755 in an effort to squeeze out a few extra frames in various programs, and I've found that, for some reason, it locks up whenever the speed goes over 700 mhz. I've tried both Pocket Hack Master 2005 and XCPUScalar 2.82, both to no avail. I have my BIOS updated to 1.10.09, too, incase that has anything to do with it.

Anyone know how to actually successfully overclock this thing? Or is it locked under 700 mhz?
