You are very lucky. My 4770k lidded cannot mantain stability at anything over 4.5GHZ (Even with VCCIN @ 2.0-2.1V and VCore @ 1.4V+). At 1.4V I'm only hitting 80*C, so IMO it's stupid to even think about the possibility of higher clocks because it'd require an insane voltage bump for 100-200mhz gain.

You are correct...probably not worth delidding that chip....Good candidates are ones that can hit 4.6 @1.2V....If you have a chip that can do that...It might be worth delidding.....Mine also had a very low VID at stock of .95V....

I like the fearless delidding approach! I'd probably go with heatgun + straight edge razor though.

So you just left the IHS off right? You did not redo the TIM and put it back on?

Ok. Thanks. I will try that.

Can you explain what is happening from a technical perspective?

I never run valley... but try again with a lower memory overclock, try +300MHz.

svl7,

I just flashed your r00 bios on my 780 SC ACX....Awesome BIOS!

My card is running a +330 offset core (1228 in shown in precision and +700 offset memory)

Everything looks great, but about 75% into the Valley benchmark run, the cards framerates drop dramatically and the Power % drops from 80% down to below 50%....Any idea what is happening here? I'm guessing some type of throttle, but that does not make sense if I'm only hitting 80% max....

Any thoughts? Thanks!

Delidded my 4770k and temps dropped around 20C. Put in under water and I'm able to hit 5.0Ghz...

Here is how I delidded..

Here's mine...new build with M6E Z87 and 4770k @ 5.0ghz

svl7,

I have EVGA GTX 780 SC ACX with bios .37. Is it OK to flash your latest Rev 03 bios on this card?
