Overclocking the 680m

What clocks are stable to use? I did +40 on both base clock and memory clock and my 3dmark11 score went up 300 points. What are you using?

 

+330 ish core and +800 mem at 1.05v.

 

Wow that's quite a bit. How did you change the volt?

 

Using a modified bios (each bios has a set voltage) and also to expand the clock range.

 

I'm currently maxing out on stock voltage, so thats 135 in the core and 480 on the mem, temps never go beyond 77.

Meaker, are those clocks damaging for the card when active 24/7?

 

You are using stock volts?

 

yep and thats as far as the clocks go on stock voltage (+135&+480)

 

my card at stock can hit +135/700. however you get severely diminishing returns after 500 on the mem clock

 

here I did a 3DMark 11 run for you, this one is stock: NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3610QM Processor,CLEVO P15xEMx score: P6134 3DMarks

and this one is with the 135/480 overclock: NVIDIA GeForce GTX 680M video card benchmark result - Intel Core i7-3610QM Processor,CLEVO P15xEMx score: P7128 3DMarks

As you can see the difference is quite remarkable, a 1100 points more and absolutely risk-free

edit: are those scores good btw?

 

What drivers are you using? I only ger 5750 something on stock clocks with the drivers that came pre-installed. I also have the 3610qm.

 

Those scores are right on the ball. i get almost the exact same using 306.23 official from nvidia

 

And when you push it:

NVIDIA GeForce GTX 680M video card benchmark result - Intel(R) Core(TM) i7-3740QM CPU @ 2.70GHz,CLEVO P170EM score: P8647 3DMarks

Basically it puts my system a generation ahead.

 

Mother of god.

 

NVIDIA GeForce GTX 680M video card benchmark result - Intel(R) Core(TM) i7-3740QM CPU @ 2.70GHz,CLEVO P170EM score: P29154 3DMarks

There's a vantage run.

I get the feeling the 680M is going to remain relevant for some time lol.

 

Is the free 3dmark11 test performance or entry?

 

Performance.

 

Wow, impressive Meaker! As the Core Clock is wrongly showing to be 324 Mhz, I take it you used the OC of your Sig?

Could you let me know the steps of your OC'ing, including vbios etc?

Just ordered a 680M myself, an Upgrade Kit from Eurocom for my x7200

 

how long do you think you can sustain that level of performance? I mean it cant be doing the card any good right? also what are temps like?

 

Thats pushing it up to 1087/2600, I use the clocks in my sig which net me around 8300-8400 3dmarks. Which is a sacrifice I know

Temps are in the 80s, would be less if I could modify the fan profile to work properly.....

 

You seriously can overclock to GTX 670 speeds with no issues?

 

I am running +135/+400 and my temps vary depending on the game. Witcher 2 and Anno 2070 are around 72C-80C, while Borderlands 2 is always in the mid 60s.

I don't understand how anyone running 1ghz+ on the GPU clock (AND a voltage increase) would not see temps through the roof.

I would consider using a modded BIOS but I am worried about temps and damaging the GPU or memory.

 

Depending on the game the clock is higher than a stock 670 boost clock....

 

Can someone please post or link exactly how and require vbioses for pushing the 680m past the MSI Afterburner limits? I've been trying to track down a central location for this, but am only finding bits here and pieces of information there. What I know so far:

- Out of the box, you can push 680m to +135mhz core/+1000mhz mem with Afterburner
- To go about out of the box OC, you need a specialized vbios

What I don't know:

- where to get the required vbios
- any particular issues or steps when flashing dual 680ms on an m18x

Any aggregation of info would be appreciated by me and, I'm sure, the larger community.

 

Techinferno got that covered
NVIDIA Kepler VBIOS mods - Overclocking Editions, modified clocks, voltage tweaks

 

Thanks. How the heck did I miss that...?
