Did I overclocking 6800ultra without reflashing bios?

Looks fine to me. But if you can get a newer version of BIOS then go for it - never hurt. Ever heard about Coolbits?

cheers ...

Past drivers 129 I think, nvidia made overclocking standard again even on locked bioses.

The major problem isn't downgrading performance, it's frying your GPU and / or memory. These cards already run extremely hot by default. Raise the temp too high then the attachment balls between the GPU and card can separate shorting your card. Some have had to resort to different hacks to save their cards like baking in an oven or under infrared lamps.

If that doesn't kill it, the GPU itself can short as the silicon wears out and the gates fail. There are hundreds of burned out Nvidia Go cards on the market precisely because of such abuse. Most on eBay now are refurbs / repairs from those units that failed in the field not from working pulls.

If you think I'm kidding do a search. You'll see hundreds of horror stories of failed nvidia laptop cards. So many in fact that there have been several attempted class action suits. Nvidia thus far has been successful fighting them of because they've been able to show most failures are self inflicted (do to overclocking).

In fact, a small cottage industry has arisen on eBay and elsewhere on the net by folks who charge $75-150 just repairing Nvidia laptop cards. The better more reputable places have high-tech machines to do the repairs. Unfortunately, others are just fly-by-night and just use lamps or bake them. So the quality of the repairs vary greatly.

Why have I gone through this long spiel? To inform you that unless you've got money to burn or plan on replacing your laptop soon anyway, it's not worth overclocking at all with these cards. The slight performance gained isn't worth killing your card. Get a newer machine with a faster GPU instead.

Learn from the others who've screwed up their rigs.

I hope this helps.

Ciao.

Worst case scenario you need to bake one day and then you just keep it downclocked forever till you get a new card / lappy. Never overclock long term an integrated vcard unless u dont care about the lappy.
