GTX 680 GPU Boost levels - what's yours?

[watto_uk]

Same. 1124. After 2 hours of Skyrim. Max temp 53C. (Water)

[QuadDamage]

yes everything @stock(100% power and 0 on GPU and MEM.)

Same here.

Plus, my boost at +220 results in 1344Mhz effective core frequency and 1344 - 220 = 1124. I've already posted multiple screenshots in the "owners" thread.

Mine (and probably Val's and watto's also) chips are very good clockers well above average. I've seen people needing 1.4V to reach 1400Mhz core and that's on water while mine can do 1344Mhz at only 1.175V on stock air.

On Unigine Heaven and Furmark mine stays at a consistent 1110. It sometimes stays at 1123 but not as frequently. I have 2 Gigabyte GTX 680

Does the boost work when you overclock your card beyond average boost? What if you overclock below average boost - would it still boost higher?

The dynamic overclocking works like this:
- Set the desired baseclock, the GPU will try to reach it if possible, if not, it'll settle for whatever it can reach below it. You can help it reaching higher clocks by putting the max poweruse limiter higher
- Boost clock always comes on top of this, and is active when possible

The dynamic overclocking works like this:

It's not "dynamic overclocking" at all. Gpu Boost bumps the clocks to Nvidias rated speed. Overclocking is taking the clocks higher than what the manufacturer recommends, GPU Boost does not do this.

The "dynamic part" is where you set the desired baseclock which the GPU tries to reach within set powerlimits. The GPU Boost, like I said, comes on top of this when possible and isn't "overclocking", but as Gvidon asked how it acts when OC'ing, I thought it should be included. Maybe I should have put it in there some other way, as at least you apparently misunderstood what I meant.

I misunderstood nothing, you implied the cards were akin to factory overclocked, they aren't. It does not "dynamically overclock," the chips are rated for the speeds they run. For example, we don't say the 2500k is overclocking itself when the turbo kicks in and ups the clocks, because it was designed that way, same thing here. Just clarifying what you're saying.

I didn't imply it "dynamically overclocks" to the boosts, the boost is separate, but the overclocking itself when you overclock is dynamic.

Manually setting a specific GPU clock on the GeForce GTX 680 is not possible. You can only define a certain offset that the dynamic overclocking algorithm will _try_ to respect. If the card runs into the power limit or something else comes up, the clocks will be lower than requested. Think of it more as a "best effort plzplz" value than a hard setting.

IE, baseclock is 1006MHz, you set your OC target to 1100MHz, it'll try to reach it, but if it can't do it within the set powerlimit, it won't be 1100MHz, but something between 1006 and 1100MHz (or even under 1006MHz if necessary)
The boost clock comes on top of the clockrate it achieves, example:
Let's assume your chip gets just to the "average boost" of 1058MHz from the baseclock of 1006MHz
You set your target to 1100MHz but the card only reaches 1050MHz, then your boostclock would be 1102MHz.

I don't trust Wizzard/techpowerup and their reviews. What does he mean by "something else comes up" anyway?

Any frequency can easily be achieved as long as the card stays within its thermal limits. It's simple : Set your desired frequency, max out your power limit and make sure your card stays at or under 70C.
