ať to hledám, jak to hledám, nikde to nemůžu v BIOSu najít...
btw někde na foru jsem se dočetl tohle:

Ok you change the AGP voltage in Freqency/Voltage Control in your BIOS. Set it to +0.3.
You alter your AGP setting in SMARTGART which is in the
Catalyst Control Centre.
I have a VIA chipset in my Gigabyte board. Which means I cannot run
at AGPx8 during gameplay.

So alter your settings in SMARTGART as follows:

AGP Speed: OFF
Fast Writes: OFF
AGP Read: OFF
AGP Write: OFF

PCI Write: ON
PCI Read: ON

--- tou +0,3 můžu nějak závažně pokazit PC, že ?
