Hmm, thats a shame
The IP-35 is an amazing overclocker board too.
Strangely though, a magazine that stated it was an amazing overclocker in a previous issue, stated in the latest issue that it wasn't that good of an overclocker... Still, its done well for me.
Maybe theres something you aren't trying, but it should definietly get to 3.0ghz. If not, you've been very unlucky indeed.
Is yours the G0 edition or the older B3 edition?
