[Official] MSI GTX 680 Lightning Owners Club - Page 458

post #4571 of 7827
Hello guys,
I just try today to overclock my 680 Lightning to +140 gpu core and +250 memory using the AB v2.3.0.
But when i'm running 3DMark11 nvidia driver (310.70) crushes out.... Any suggestions? I think is not very high overclock for this card... or my card does not overclock well?

I'm using .3A LN2 unlocked bios.

Try to lower your core clock, my rule is that start as high as you think might go, and lower it by 15 or 10 each time it fails.

This is what im getting, am I missing something?

Temps seem way high and I cant seem to get anywhere near some of the oc's I see on here without getting artifacts about 5 minutes in.

how close are the card to other components that make heat?

Have the fans some room to blow the hot air out?

Thnx Moozoren for your answer. I think i'm stable only @1320 at unigine frown.gif
Also, i notice that the GPU Voltage does not increase if i set Core Voltage to +100, it stays at 1.2120 all time. Is this wrong?
post #4575 of 7827
Yes, it is not normal, when I set the core voltage to +93 (the maximum value when i hit apply button) and test with Unigine Heaven 3 or 3DMark11 the core voltage goes to 1.365V , measured with Digital multimeter. The values that MSI AB shows are not correct, do not trust them. Use multimeter to measure the voltages directly from the card.

And at GPU-Z core voltage is incorrect?



I'm not happy with my overclocking results....frown.gif

Is there any way to pass 1320?

Hi i have some problem with voltage, im on LN2 bios (80.04.28.00.3A) but on load and +99 coreV in cpuz show 1.1750 V (max) with AB 2.3, where is problem.

Don't trust in the AB read, that read isn't good. Use a multimeter and the voltage read points.

Hey guys, im having some temperature problems with my first card, before with default settings i get below 60c at full load. Then i was using my card with OC settings. +100clock and +300 mem. Full load was below 70c. Just now i decided to use the default clock settings again and same fan settings. But my temperature is going up to 70c+ now.. What seems to be the problem? I already did a fresh install of the drivers and still the same.. Both cards are on LN2 3a Bios, driver version 310.70. Using evga precision.

70+ is certainly a bad thing
