All I know is it is physically disabled.

It's not possible on this laptop. You can overclock the lower P-states a bit in Nvidia Inspector but you'll never get full power on battery.

LOL Brian just went full fanboy.

Yes it does. Technically LCD overclocking works on any laptop without switchable graphics.

Modded BIOS won't give you access to iGPU, it's locked out at the hardware level.

That's bollocks. Hardware whitelist is far from being the only thing that's crippled with the stock BIOS.

Yes.

Go to sound settings in Windows Control Panel, double-click on speakers, Dolby tab, click power button to turn off:

You sure about that? I seem to remember there's something in the Realtek HD Audio Manager. Also try turning off Dolby Home Theater.

Yeah turn down the gain and then see what happens.

Your motherboard is FUBAR. Time to get a new one. Lesson of the day: Don't ever run the battery gauge reset. :\

Gotcha. Regarding my CPU temps, I do have Ivy Bridge instead of Haswell, so...

Damn, those are some pretty high idle temps. I'm at about 40C on CPU and both GPU's. Do you live somewhere hot? LOL 750M SLI with only the 768p screen. That's overkill.

Is this actually stable on an overnight run of Unigine Heaven at max settings?! o_O Pretty crazy if true. You must've lucked out and gotten a golden sample or something. That's by far the highest overclock I've ever seen on stock voltage. I can only get 1150 MHz core @ 1.050 V and 2250 MHz memory on my 650M SLI. 78.0% and 84.5% ASIC quality on primary and Ultrabay respectively.

One of the VRAM chips on the Ultrabay card is missing a thermal pad for whatever reason. You should put one on.

I've always heard to stop the fans when blowing them out so as to not damage the bearings. Yeah if you don't have the mesh removed it's probably a good idea to remove the bottom cover. Just be careful as the plastic tabs holding it in place break easily. Wedge your fingers in between there and gently pry up and in as you work your way around the edges. It's very tight the first time you do it but gets easier after that.

You can also toggle it at will with the hotkey.

I don't take anything apart. I have the cloth mesh removed, so I just stick a couple pins through the dust cover to stop the fans and blow through the exhaust vents and I/O ports with a can of compressed air.

Inspector is an indispensable program for power users because of its game profile tool. If you want to set custom AA and SLI flags or assign different profiles to games, you need Inspector. Considering the sorry state of SLI support for most new titles (and many older titles) and the lack of AA options, you couldn't pry Inspector from my cold dead hands if you wanted to. The GeForce 3D Profile Manager is much less intuitive since you're basically just editing the raw XML file. Afterburner and Precision are designed for desktop cards and can't adjust voltage or power and temperature targets on most mobile GPU's even with a modded vBIOS. And I don't believe you can individually adjust cards in SLI either. Afterburner has really beefy hardware monitoring and game/desktop recording functionality as well as much better support from the developer. Precision was abandoned by that same developer and the most recent release was taken down due to EVGA's plagiarism. I personally stick with Inspector and Afterburner.

And how much increase does DDR3-1866 give you, 0.5 FPS at most? Seems like a poor investment from price/performance standpoint. Anyway, Intel's iGPU's aren't fast enough to gain much benefit from faster RAM, especially a bump as small as 1600 to 1866. With Kaveri, though, I can understand since it's more bandwidth bound and can really benefit from fast RAM, especially if you can OC the memory controller.

Do you game on iGPU?

He's on vacation I think?

LOL didn't know this forum had a language filter, I thought that was NBR's thing.

Definitely not right. You should be getting at least 1000 points higher than that at stock, more if you OC. Check my sig, even my 3630QM got a higher score.

Sure, if you count hitting a measly 425 MHz while still running hot and barely outperforming a Mobility 5870 at twice the TDP something to brag about.
