Fairly new to the forum, tried searching this thread for similar issues and couldn't find anything, I'll admit I haven't gone through all 1800+ pages, but the search tool didn't give me anything to work with.

Got myself a MSI 780 Gaming (N780 TF 3GD5/OC) a few days ago and I'm having an issue with overclocking. It handled up to 1302 core, with memory at 6832, at 1.175v, according to Afterburner . I ran Kombustor's stress tests for a fairly long time (~6hrs), fully stable 99% load (iirc, i used the flame test with 400k particles), no problem whatsoever, at around 60ºC after 30min and for the remaining duration of the test, fans at 75%.

I decided to go with 1241MHz instead to make sure things go smoothly and everything's fine clock-wise on stress tests, even gpu-z's render test gets the clock to 1241. But when I run games or the Heaven benchmark.. It clocks down to 901MHz, sometimes lower, sometimes spikes up to 1180'ish.. . I can get it to 1241 for a while if I run the stress tests with the game running, but if I turn the stress test off it's a matter of 1-2minutes until it downclocks again. It's as if the card thinks the game/benchmark doesn't need that much power, even if I'm under 50fps at the moment and it clearly goes up after I artificially raise it with the stress test.

Being new to a lot in overclocking GPU's (my old 560 Ti didn't downclock regardless of what I did with it, not even idle iirc) I'm unsure of what to do at this point.
I am using the stock BIOS since I have zero experience flashing GPU bios and I'm not sure what's compatible with each version.

Any help deeply appreciated!

Read my guide for a few pointers:
OCCAMRAZOR ADVANCED GK110 OC GUIDE

You could be hitting a TDP limit!

Read also my article on TDP:

"The PT is the increase of TDP (thermal design power) which is determined by the chips maker (GK110 =250W) but this is not a fixed value, refers to the maximum amount of power the cooling system, in this case a chip, is required to dissipate. The TDP is typically not the most power the chip could ever draw, but the maximum power that it would draw when running "real applications". This ensures the chip will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power.
"TDP is meant to be the wattage of the processor at load. I say "wattage" because it is unclear if this is meant to correspond most immediately to how much power is consumed in watts, or how much heat is produced in watts, but as near as I can tell the TDP is pretty much meant to indicate both" GL



(where C is capacitance, f is frequency and V is voltage)

Now, you dont have to make complicated calculus or anything like that because you have this chip here:



It monitors real-time voltage and power draw and its where AB gets its reading from the VRM´s! wink.gif

Stock bios come with 250W TDP (AKA PT) so when its at 100% you will have 250W of power draw, if you increase it to the max stock 106% youll get: 250x106%=265W
The same is with modded 300/400/500W bios what you see in AB or precisionX is the percentage above what you set!
Ex: with a 500W bios (Slider set to maximum of course) you see 60% usage, this equals to: 500x60%=300W
YOU CAN DIRECTLY CONTROL TDP WITH THE SLIDER! thumb.gif

Now, why has AB a 300% slider while PrecisionX uses 200% for the same bios with the same PT?
Well, AB and precision have different interfaces so the readings are different for the same thing, just keep in mind the base TDP value and make your calculations from there
It doesnt matter what the % slider is in any program, just increase it if you having stutters or frame drops and when making calculations always make them from the base TPD:

aW x b% = cW (a= bios base TDP, b= OSD TDP, c= aproximate power draw)"

Can anyone clarify for me that these resistors, or whatever they are, are damaged and is the reason my card wont work at 16x I looked in the box it came in and was able to find one of those little peices

16X PCIe 2.0 with SB.


Open GPU-Z and start the render test. Check your link speed then.

Hmm, I got most of that, I think. But
I'll definitely take time and read your full advanced guide that I somehow missed on the very first post, as it seems to be the best way to go about this. Love a well-structured guide.

That said, wouldn't the TDP limit be hit when doing the stress tests as well? (currently the Power Limit is at 103%, which is the maximum on AB, likely due to me having the Stock BIOS, I'd wager.)
It's just odd (for me tongue.gif) to have such a great result out of stress testing with high loads and then have it go down during real gaming scenarios with comparatively lower loads on the gpu.

its showing 8x at 2.0

Mine also idles @ 1.1 speed: Warning: Spoiler! (Click to show)

However I just read your edit and finding that small resistor in your Mobo's box is a little discerning.
But if it works as it should then I guess no need to worry about it.

I can not get the card to boot in the primary pcie slot unless there is another card in the case along with it, it will boot in the secondary pcie slot but my secondary runs at only 8x, I cant get this card to run 16 lanes and if you count those resitors there are 16 on there and 2 are busted so is that possibly why im not able to run the card at 16x? In my primary pcie slot this card wont even turn the monitor on when computer boots, no bios logo, no nothing, but the card runs fine as long as its put in an 8x environment

Is there any way to save the stock bios? Just in case

Yes; you can save your stock bios with GPU-Z; click on the little icon next to BIOS version.
