I have a gtx680 lightning, i use the normal bios, and i have oc'ed to +67 on core and +400 on mem with +63mV I bumped up the power limit to 133% And i must ask, why when i play games, i have spikes for 1 second from 133% power to, for example 145% or 177% The msi afterburner graph shows a spike to that power level for just one second, then the power limit is back to below 133%. Is normal to have more than 133% power spikes ? If i let the card on stock, i don't have spikes...
If i switch to LN2 bios which as 300% power limit, then in games the power never goes up from 120 max. So it's a bug when i use the normal bios ?
For example if i switch to LN2 and i use the same OC setting and volts, the power is nice and stable, with no spikes.
