Score: 1150
Min: 21.3
Max: 118.8

The GPU clock is much more stable than before but oscillates in some areas. http://cdn.overclock.net/4/4b/4b637587_precisionx.png Got flat lines in most areas at 1250Mhz.

Whoa, so stock clocks, ref 670, and it boosts to 1254... I think the "problem" may be you have a considerably faster than average chip smile.gif

That's awesome. My ftw card didn't boost over 1175 until applying offsets for comparison. The wiggles down in clock on your latest run are due to power usage, you can see it topped out at 149% usage at some point, but the gpu clock is mostly flat at its max boost. Also got warmer running at these speeds but not too hot. So your gpu boost clocks up pretty high already with no offset, adding mem offset will help it do more work faster, but probably also increase power usage inducing throttling again. You're probably going to be held back somewhat by only being able to dial in 122% as the max power target. Your card looks like it varies in a good way smile.gif

Haha, that's great to hear smile.gif Feeling more relieved now lol. Anyway what might be causing the card to go over the power target of 122%? Could it be because of the GPU boost?

I think so, it just uses more power to run at the higher speeds that it happily wants to boost up to. At least that's how it looks to me. I'm curious what gpuz reports as the ASIC quality of your chip? If you right-click the title bar in gpuz, there's a menu item that says "Read ASIC quality...". I'm guessing it will report a nice high number, but am curious to know what it really says. I got 73%. Also curious about what gpuz reports as your default and boost clocks?

I'm not one for patching bios's usually, but it may be that for you to get the absolute most out of the card you have, a bios that allows you to dial in a power target greater than 122% might be just the thing. A card that runs at 1254 at stock clocks seems pretty sweet to me. How you deal with overclocking it will be a little different than what most folks do. You realize that in many cases, the goal is more or less where you're starting.

Got an ASIC quality of 80.1%. Default Clock of 915Mhz and boost clock of 980Mhz. http://cdn.overclock.net/7/77/77fe7f4d_gpuz.png Wow, so you're saying that there's not much need for me to overclock?

Right, its already running pretty fast, but you might want to increase mem clock to balance things out.

Your card is practically running a +175 core offset already. It boosts to clocks that most people would need a hefty offset like that to reach.

Probably your gpu is capable of running at yet higher core clocks, can't know that w/o trying. But when trying you'll quickly run into your power target limit and it'll throttle (that's what happened on you when you tried to run up the clocks to start with).

For comparison, with my ftw card
at stock, default: 1006, boost: 1085 --> max realized boost 1175
at oc in sig, default: 1101, boost: 1180 --> max realized boost 1267
i put my power target at 130%, the factory ftw bios lets me run it up to 145%

You card's kepler boost is way better than mine.

Unless you want to void the warranty and flash a different bios, I think you might want to leave the core offset at zero (or only very small increments like +13 +26).

yes bent, see how high you can get your memory. start at 300mhz and run heaven 3 then heaven 4 then valley all at highest settings. see if any of those give you artifacts. post your results here. thats a pretty nice card. raising your memory clock will give a good boost.

its kinda low ,right?

seems like a hefty mem clock to me and core ain't bad at all, if you reduce mem can you get more on core?

That's awesome. My ftw card didn't boost over 1175 until applying offsets for comparison. The wiggles down in clock on your latest run are due to power usage, you can see it topped out at 149% usage at some point, but the gpu clock is mostly flat at its max boost. Also got warmer running at these speeds but not too hot. So your gpu boost clocks up pretty high already with no offset, adding mem offset will help it do more work faster, but probably also increase power usage inducing throttling again. You're probably going to be held back somewhat by only being able to dial in 122% as the max power target. Your card looks like it varies in a good way smile.gif

I think there's been a mistake. If you look closely at the graph again the GPU clock cannot be at 1254 Mhz. If it was 1254 the line would be somewhere in the middle of the vertical axis. I did another run on heaven3 on default settings and here it is http://cdn.overclock.net/6/6c/6ccd8594_heaven3.png That reading of 1254 Mhz could have been an earlier reading. I still got the same result though.

Hi, here are the results at default GPU clock and +300 memory clock:

Heaven 3:
FPS: 47.1 Score 1187 Min 22.7 Max 120.4

Heaven 4:
FPS: 34.9 Score 880 Min 17.3 Max 78.4

Valley 1.0:
FPS: 43.3 Score 1810 Min 24.3 Max 78.3

Are these results ok?

I ran Heaven 3 again at +150 GPU clock offset, +200 Memory clock offset and got these results:
