Scratch that, gave it a little nudge and topped out at 87 degree temps. This one scored 8384 on the graphics with a final score of 7925. Might back it off a bit, but I will play a few games on it like that.

Awesome! Ty. Just got done running 3DMark and I hit 8089 on graphics with a +105 and +100 from you were at. I had to raise the voltage a bit, but temps are in the mid 80's at most it looks like. I may leave it right there as that is already a gain of almost 700 from what I did on my stock bios OC. About 1000 score gain from the stock clock.

Sorry for a delay in posting this Klem. Here is my stock vbios. Looks like it is just power capping right now. I would like to squeeze out a bit more. I have the same machine as the original poster in this thread.

Pretty good though, I have yet to reach anywhere near. Especially on the physics score. I have the same processor, but always sit at around 6800. You are beating my on the graphics score by about 700 though too. I settled at +75 and +550 and am nowhere near that number.

Thank you very much Klem.

I've used that bios you made for me as guideline for customizing with Kepler Bios Tweaker and what I discovered is that the third and fourth to last entries in the power table are actual power targets(already saw that in the OC Bios but since that was heavily customized I wasn't sure).

So what I ended up doing was setting the Def and Max of those 2 entries to 125000mW(That's all I've modified from stock). Doing so gave me some pretty impressive results as I was able to go 1050Mhz on the core and 2750Mhz on the VRAM using inspector, what is more impressive though is that gpu boost was doing his own job with the voltages so that it was stable under stress(3D Mark11) by giving it automaticly 1.37V. Temps never even reached 80C.

The 3D Mark11 score was also very good as it reached a score of 7807 in the Graphic Score and all of this while still being able to run any games on battery.

Have you taken the OC any further to see what it is capable of? Also, I noticed I could play around at least a little bit with the battery settings in the nvidia console, but that only made a minor improvement to games on battery only.

Yes that's because the stock bios regulates the frequency according to power consumption which means that under 3d mark11 it won't run at +80 on the core for most of the time since it's a very intensive task. You could easily see that if you use msi afterburner overlay to see gpu frequency while you're running the test. You can solve this with the OC Edition bios of svl7 however that, atleast at me, breaks the ability to play any games while on battery. To my understanding if the power target could be increased it would be possible to run up to 1050MHz on the core as the maximum voltage it applies is 1.37 which is enough for that kind of OC(hence why you crash if you go past +80). You could go even higher if the voltage was unlocked however you might wanna make sure you got temperature room for that.

May I kindly ask you for that modification too?(This vbios is from my XMG P504)

Ah, ok, it has been perfectly stable at 80+ and 550+ the last week. I have not seen my GPU temps ever go higher than 83c even after a few straight hours of gaming, so I think I have a little head room still. Thx for posting the stock vbios for modification. I can't download attachments yet it looks like.

Hello, I just recently received my new NP8278-S with the 870M. I downloaded Nvidia Inspector to do a little overclocking as well as 3DMark 2011. I was able to get up to +80 core offset and +650 Memory, but anything higher and 3DMark starts crashing. Voltage does not seem to be making much of a difference. My highest score I could obtain for the graphics was 7478 with a final score of 7268 combined. Any help would be much appreciated. Let me know what you need.

Hello, I just received my new NP8278-S earlier this week with a 870M. I attempted to overclock it as well and ended up with +80 on the core clock offset and +650 on the memory. I unable to go any further without crashing 3DMark 2011 and the voltage adjustment does not seem to make a difference. Also, my graphics score ended up being 7478 with a final score of 7268. Which is a bit lower than some of the others I see here. Any advise or help would be much appreciated.
