The MSI GTX 680 Lightning does not support overclocking.
Hey everyone. I just got an MSI GTX 680 Lightning, and it’s really good until I try to push it overclock. I use MSI Afterburner for overclocking and Unigine Valley for testing. It works okay at default speeds, usually around 45fps. But when I crank the core up by 10MHz, my frame rate drops to about 22fps on average. My settings are: core voltage +100mV, memory voltage +100Mv, auxiliary voltage +50Mv, power limit +133%, core clock +0MHz, memory clock +500MHz. Even after removing the overclock, it keeps dropping. I’ve uninstalled and reinstalled Afterburner and drivers from Nvidia’s site, using the newest versions. Anyone have a clue what’s happening? This machine is supposed to be a powerhouse for overclocking. Thanks!
you shouldn't increase the voltages to their maximum, just keep them at the default level, then you can overclock. once stability problems appear, raise the voltage by 0.5 volts. now that the voltage is higher, it becomes very hot, which causes it to slow down, resulting in lower FPS.
I increased all settings and monitored the temperatures; they remained consistent at 60C during the stress test. I’ll try your approach just to confirm if that’s the issue causing the low speeds. Do you have any idea why it doesn’t overclock on the core? I got it to +25MHz last night, but going to +26MHZ caused a crash.
you gonna cause damage, Your simply not supposed to give it that much voltage, try +1 on all the voltage settings, then overclock. You will see an improvement. Some one else did the same thing as you yesterday, and i told him the same thing. here the link:
Hey dude, I lowered all the voltage to stock, and everything stayed at the same temperature, but I still couldn't overclock. I kept raising the voltage in 25mv steps until I hit the max again—temperature didn’t change, and I still couldn’t get any overclock :/
Hey there,
I adjusted the voltage to the stock level, and everything stayed at the same temperature, but I still couldn't overclock. I kept raising the voltage in 25mv steps until I returned to the maximum, and the temperature didn’t change, yet I still couldn’t get any overclock :/
What tool are you using to check the GPU clock? Downloading the GPU Z will give you the real clock details.
I'm using both GPUZ and msi afterburner, and following the guide turned out to be exactly what I needed. I began from zero, gradually raising the core clock in 10MHz steps, and once it failed, I increased the voltage. I reached +26MHz before it crashed again, kept pushing the voltage higher, and it continued to fail, even with memory at +500mV. At full voltage and memory set, it crashed at +26MHz and then dropped to +25MHz with all previous settings intact, which now works properly. It's odd that this card was designed as the top overclocker, yet it doesn't keep going higher. :/
