CPU is unworkable after Radeon install

Dwilly · 26 Jan 2008 at 00:22

I just installed a HIS Radeon 3870 into my Fatalty F-190HD. To fit it in I had to switch one of the SATA drive ports to make room for this gigantic card.

Now on boot up I'm getting a 'CPU has changed or is unworkable' BIOS error, boots into Vista OK but I get intermittent system crashes. Do I need to do something in the CMOS to account for the SATA switch? Or anything else?

Thanks

"CPU is unworkable or has been changed" is quite normal on an abit usually on 1st install, clearing CMOS etc.
Usually it's just a matter of going into the BIOS, selecting optimised defaults & saving. (however, on a DDR2 mobo make sure that the RAM voltage is set to the manufacturer's recommended voltage & not the JEDEC 1.8V)

Thanks, got rid of the BIOS error, but Vista is crashing now the odd time (complete restart of the system). Seems to be sometimes when games run in 1920x1080. ATI Catalyst seems to be up to date. Anything else I can do? Cheers

it's hard to say without knowing the system specs.
