Maybe somebody should test power consumption while adjusting power limit.

I feel like Nvidia just threw that power limit thing in there to make overclockers feel special because if they unlocked voltage control we'd be able to clock these things way faster than they intended. Or these chips melt with a little overvolting and again they threw it in to not piss us off.

As someone who's chip only does a pinch over 1200 it makes me really bitter voltage is locked.

hi!

dcII owners please try this tool http://www.galaxytech.com/files/XtremeTuner%20Plus%201.0.1_20120419.rar
this tool should allow you up to 1350mV on VGPU
If the program does not try "run as administrator"
please inform me if it works properly or not ... thanks thumb.gif

Here is my ASUS GTX 670 TOP 2GB score for 3D Mark 11:

GPU-z shows at stock the 670 TOP can boost up to 1254mhz tongue.gif

Amazing card!

Planning to grab a 2nd for sli!

So maybe you could test that 2500K at about 4700MHz (I can do about 4450MHz with my chip).

I didn't your message above after I started my benching but here are my results. My GPU is the Gigabyte GTX 670 WF3. The CPU speeds are 3.6GHz for stock and 4.9GHz for OC:
Heaven Comparisons (Click to show)
Stock CPU / Stock GPU
338

Max Clocked CPU / Stock GPU
338

For this next section, I noticed that I could not get higher than a +100 Core clock offset for the GPU when my CPU was stock. I did see small artifacts in Heaven when running with the +100 Core clock offset. I don't know if this is just my mobo or not as I currently do not have access to another mobo to test this against.

Stock CPU / OC GPU
338

Max Clocked GPU / OC GPU
338


I did some tweaking when it came to 3DMark11 as I would get better performance with a lesser GPU Core overclock. Like above, I used +100 offset. Here are the links: 3DMark11 Comparisons (Click to show)
Stock CPU / Stock GPU

Clocked CPU / Stock GPU

Stock CPU / Clocked GPU

Clocked CPU / Clocked GPU

Here is a maxed GPU clock and CPU. The Core clock is +118 offset
Clocked CPU / Clocked GPU w/ +118
As you see, the graphics score takes a beating.

As shown Heaven doesn't care about the CPU. 3DMark11 does take the CPU more of the CPU into account and seems more... sensitive to overclocking of the GPU.

My Asus Direct CU II TOP GTX 670 is reaching 108 on the power control stock so it must vary per card.

1310 Mhz with a 110+ boost. Still 100% stable, going to push it more to see when the card finally crashes. I am surprised that I actually got a good OCer for once. If I hit 1.35Ghz, that would be sweet.
