Even when using a modified vBIOS?

TDP is technically the max amount of power the cooling system needs to dissipate in order to keep the chip at or below its maximum temperature. The default for the 670 is 170W i believe and if you go higher than that the card will throttle to keep it cool so raising the TDP slider will let you go over that to prevent it from happening.

Hey guys i have a problem similar to ClemC
I have a new ASUS GTX670-DC2-2GD5 with voltage seted to 1150 mV and power limit at 122% ( the poer limit never pass 100-103% in games or heaven benchmark ) the problem is that the card crash at lower core clocks in games/heaven benchmark but it can run at higher clocks in kombustor-evga oc scanner- occt 100% stable for hours. The only difference from games-heaven benchmark and kombustor-evgaocscanner is the power limit, on kombustor-evagocscanner go up to 128% and in games to 100-103%.
I'm using Windows 7 64bit - EVGA Precision 4.1 - Geforce Drivers 314.22
Any ideas?

Sorry for my horrible English!!

I would say that neither the MSI nor the EVGA testing tools are of any use really. I can hit 1280 - 1306 Mhz while testing with them and Heaven 4 wont even load the test with anything above 1241 Mhz.

no. TOP cards are nothing more than factory overclocked cards.

Can anyone confirm this ? I cant even get the voltage slider to do anything on my end frown.gif

My card is a 670 FTW, which uses the 680's reference PCB.

Looks like you have something blowing on to the card still to cool memory/vrm?

EDIT: Durr you said you have the bracket with the fan mount.

Thanks for this guide!

I am in the process of using this on my new 670. I am a bit confused. I see 3 different clocks happening:

GPU-Z says my boost is 1140, but the sensor reads ~1251. Afterburner reads ~1215, and Valley 1.0 says ~1320. Which one is correct?

Thanks in advance!
