My Lightning shipped and is on the way wheee.gif

Is max voltage (+100 mV) ok for regular gaming? It appear the max clocks I can get on max voltage are 1280/6800, and any voltage lower than that brings artifacts. It seems like a LOT of voltage for such a "modest" overclock, but if I can't even run those clocks while gaming, I might as well not even overclock and play the games on the default 1202 MHz clock, which kind of defeats the purpose of purchasing this card.

This thread is huge and it's hard finding the information I need. I am thinking of purchasing this card and was wondering if someone could help.

1. Is there a guide of sorts on overclocking this particular card?
2. What is safe 24/7 voltage on these ?

I just got my cards so others will be better able to talk about voltage. But for an overclocking guide I'd use SeanPoe's GTX 670 Overclock Master-Guide. It doesn't go into voltage increasing, but gives a really good overview of how to start.

Yeah that's a good start if you want to go over all the basics. Voltage control and temperature monitoring is something you have to know about though with the Lightning, and also that they don't throttle so watching temperatures is up to you. Just go about overclocking the Lightning the same way the guide says to overclock a reference card, but when you crash, you can increase the voltage instead of being out of luck biggrin.gif Get Afterburner 2.2.3 and good luck. Just keep temps relatively low, in the 70Cs, which isn't hard.

You'll have to flash your card to the unlocked LN2 BIOS too I'm sure. There's a video on the other page on how to do it. It's pretty easy.

A little update on my overclocking. At max voltage on the core, memory, and aux, so far the best clock is +60 core (1254 MHz), +350 memory (~6600 MHz), power target +300%. When benchmarking, my GPU load is 99%, temperatures around 60 degrees (highest fan around 70%), but I noticed that my power percentage shown in Afterburner was only about 60%. Is the power percentage suppose to read that low?

My LN2 .3A bios doesn't work stable.. Why ?

No wonder u get a bad clock on 70% and 60 degrees is real bad, means you got 0% air flow so tha card sucks its hot air back again and back again. 680 should get get 40-50 degrees on 70% fan speed.
I dont understand why people like you buy this Lightning card and got zero percent airflow...

If you got a fast car you need some good wheels too,

this is on 1306/7800. Did 5 heaven runs on it / Fan speed 65%

I can get 8000mhz too but but need fan speed crazy high and only BF3 runs on it,
Ran BF3 for 3 hours on 8000mhz, says enough! But fan speed on 100% is bs tongue.gif.

And yea, anything above like 6700mhz is pretty high allready since 6000mhz is allready pretty maxed out

I can get 8000mhz too but only in BF3, heaven craps out on it in 1 minute

I don't understand your thought process. How is keeping my GPU temperatures around 60 degrees, and on my auto fan setting having the highest speed reach 70% (on my custom fan profile) an issue? Could you elaborate please? I wanted to also point out that my case is a Corsair Obsidian 550D, which uses sound dampening technology, which I've heard does an above average job on cooling even with the lower ventilation it provides.
