'Select Proper Boot Device'

Limehouse · 4 Feb 2007 at 12:50

Today i've been OC'ing my P4 2.8 Prescott and I've gotten the Cpu Freq up from 200 to 241, but as soon as I get it over 241, a message comes up saying 'Reboot and select proper boot device or insert boot media in selected boot drive', I'm OC'ing in Sync so my PCI-E frequency is 120, if I chose async. I'm using an Asrock 945g-DVI Motherboard.

Thanks,
Limehouse.

try upping the chipset or cpu vcore, the pci-e bus should have anything to do with that.

basically it sounds like you've overcooked the overclock, sometime a pc won't POST sometimes it says stuff like "select proper boot device" and behaves like there's no hard drive there.

In this BIOS, there isn't actually an option to set values for the voltages, just 'high, medium, low and auto.' Put it onto high, and I managed to get to a magical....242, i more than when it was set to auto, marvellous.
