As dph314 said, that is normal for the regular stock bios, with any card the true voltage is rarely the same as software reported voltage.

Ah, better luck next time dude. Thanks dph314 and ftw for the info

Well so far i've managed to record max 1304Mhz on the core using ~1.260v stable in bf3 (played for about 30 minutes) and did a few runs of heaven. Yet to do 3dmark 11 or vantage, they seem to hate 680 cards and always give me errors when i start them up.

Now that i've got to the 1300 mark I think its a good time to stretch out the memory for a bit. Whats safe amount of voltage to do on the memory? The MM reads about 1.617V when under heaven.
And another bit of guidance please smile.gif can anyone give me a heads up on potentially having an unstable card if both memory and core are fine when overclocking each individually, but get unstable applying both stable overclocks at the same time? I'm not a total noob at overclocking biggrin.gif, but i'm by no means an expert smile.gif

Thanks!
I usually OC the core first & then overclock the memory while the core is overclocked. Testing max memory by itself & then using that with max overclocked core can be unstable, they have to be somewhat balanced to play nice with each other.
I haven't touched memory voltage while the card is under normal cooling, can't help much there.

I should be getting my 680 Lightning sometime this next week. I'm a GPU OC noob, but this thread seems to have a lot of awesome info and helpful people. Looking forward to joining the ranks and contributing any helpful tips I pick up on my way to becoming a pokémon overclocking master!

Welcome aboard, I'm dumber than a bag of hammers and I did OK OCing these things!

Hello guys

After trying some luck with msi 670 pe I decide that I want to step up to 680L. The nvidia forced bios make me sick I'm glad there is a way with bios flashing . I believe I read somewhere on guru3d forums that never batch of cards could be hardware limited to go only 1.175v I'm not a pro so I'm asking you is it possible my 680L is in mail and I'm concern now. I appreciate your answer.. thumb.gif

If it does come with a voltage limiting bios, you can flash an unlocked bios on it & get full control. Haven't heard of anyone getting a locked one yet though.

Hey Guys! I just recently received my lightning 680. After a week of trying to push the card to its max, I ended up with 1310 core and 6800 mem as my max. I am definitely disappointed, and wondering if this is the norm. I have heard of people pushing mem over 7000 and core past 1350. I did notice my power usage is only about 65% sometimes 70%. Is that normal? I had an EVGA SC Sig 680 before this card and I had a 1300 core and 7100 mem, so I see this as an expensive downgrade. I was using the ln2 bios with voltage maxed out at like 1.289 or something like that. Thanks for any insight!

Check what the bios number is? You might just have a locked bios and the max voltage might only be 1.1750...

Did you check up with th MM ? Max voltage shold be around 1.36-1.37 on LN2 BIOS.
Every chip is not the same and the overclock is not guaranteed smile.gif

1.289v in software? That's not really reliable. I'm not home now, so I forgot what voltage I'm running when Afterburner shows 1.289v.
