The issue I'm talking about isn't the temp itself, its the fact the fans don't spin up until a much higher temp than they did with the stock vbios. Once they kick on it can cool itself OK, but that's currently happening at 87'c, so it gets there much faster under load than if they'd come on earlier. I can force them to spin up with the old fn+1 trick, but having to do that all the time is a bit annoying. I only really see those extreme temps when running benchmarks which hammer the hell out of it (around 80'c is the most I tend to see when actually gaming). I'm currently using I-C Diamond 7 paste, and before I applied this stuff I was seeing 90+ core temp on stock clocks, never mind the insane OC I'm now running with your modded vbios, so I think the paste job is pretty good.

What happened to your card? I flashed the modded vbios and had a very strange mad bout of 'I thought I'd killed it' artifacting on my 780M when I tried to push the core clock over 1GHz, but once the card had re-set itself due to optimus it came back from the grave, and I'm now running it OK at 980Mhz core / 2800 MHz memory (Clevo P170SM chassis).

So I got the modded vbios installed on my 780M, and it works fine and has fixed the throttling issue I was having, so thanks very much for that! I have one problem though in that it seems to have modified the thermal targets for the fans on my machine. They seem to currently bit kiking up to high-speed at 87'c, which is a bit warm if you ask me. With the stock bios they come on to full blast around 75. I don't seem to have any option to set a manual fan speed profile through NVidia Inspector or MSI Afterburner. Is this something casued by the bios? Can anyone recommend a speed controller program which works with the Clevo P170SM chassis?

I'd also recommend getting the latest version of the Intel graphics driver for your iGP, since as best I understand it the two drivers have to talk to each-other for optimus to work correctly. You can force an application to use a particular GPU via the NVidia control-panel (just create a profile for the application under 3d application settings and set the preferred GPU to 'High Performance NVidia'), or in some cases via a windows context menu. My biggest problem with Optimus is trying to get good results with vsync. Forcing vsync in the NVidia panel enables it for some things, but others (most specifically OpenGL applications) refuse to sync but still cap to 60fps, resulting in horrendous right-in-the-centre-of-your-screen tearing. If anyone has a good solution to that one I'm all ears.

If you're even remotely a fan of '80's action' style movies (think anything featuring Arnie or Stallone) then get Blood Dragon, its a great time. Same FarCry3 gameplay just boiled down. Shame the campaign isn't longer (those missions are the best part), but its worth the price of entry.

Hi guys, I'm going to give the 780M vbios a shot. I'm currently getting reasonable results at 954MHz core, although pushing it any higher than that causes it to throttle, and trying to push any on the memory makes it throttle even harder. I'm a bit concerned about my temps though, currently it evens out at 85'c in Ungine Valley, and that's with I-C Diamond 7 paste (I'm running a Clevo P170SM chassis). I've read of people getting amazing results on the same chassis with even higher clocks. I never get any artifacting or other signs of the chip being defective. Anyone running a similar chassis getting better temps?

I'd recommend the 'medium' texture quality if you want to avoid the texture thrashing problems. Watch_Dogs eats VRAM like its going out of fashion, I get these issues on the 'high' setting and I'm running 4GB VRAM.

I got real lucky on a i7-2920XM CPU for my R3, works a charm, so any i7 CPU will be fine. I can run this at 3.6Ghz without the temps getting too high. Just about to replace the AMD 6990M I have now with a 680M from an R4. Hopefully that'll be a simple change.
