Great guide btw, Improved my Heaven score by about 180 points smile.gif
The overclock and fan settings are only active when precision-X is open and running (minimized to the tool-try is fine). So yes, this is normal and yes, you will need to launch precision-X after each computer restart.

Really? I know the voltage is never there but the OC and fan settings are always there. If you check "load at startup" (whatever that checkbox says), it should load it. Now, having said that, I noticed that until I loaded the 304.48 beta drivers that is was consistent in doing this.

Went through the quick and dirty route of overclocking my 670's, and this is what I got. Does it look like they're pulling in a good score?

I've been experimenting with my ASUS 670 Top and think it is a dud.

I'm using the latest BIOS for the Top (which seems to lower Kepler Boost around 43MHz??) and my Kepler Boost is only +26! I've been able to overclock to a Max Boost of 1202 for several runs of Heaven before it crashes on max settings @ 2560x1440, but can't go more than about half an hour. So... to keep it stable, I have to keep it around 1163-1180 MHZ, which is under where it would have been running stock with the first BIOS -- (which would have been around 1205 based on a 26-43 = 69 Kepler Boost. I'm thinking that, had I not updated the BIOS immediately (I updated before testing), I would have had an unstable card at stock settings.

I'm using Precision X and setting the voltage to max and power target to 117%. My idle temps are around 30C, and I rarely get above 60C under load.

My monitor is 2560x1440 (my iMac) and even at stock clocks, Heaven does not run all that smoothly at that resolution. It's not awful, but seems to give me tearing and some stutter (not sure what the appropriate lingo is as I am new to this). I've been scoring around 770-790 at just over 30 fps at that resolution. At 1920x1080 (but still using my iMac as a monitor), I get scores between 1170 and 1190 at around 45 fps. I haven't been able to stably boost my memory much at all . . . maybe +100.

It seems as if I have one of the slowest still functional 670 Tops out there. I'm wondering if I should I return to Newegg and try again, or if should I be happy with what I have. I had a standard EVGA 670 before this, but it sounded like someone put trading cards in the spokes of a bicycle that had a dyson vacuum cleaner strapped to it. It's been running Skyrim pretty well (as long as I have VSync on - otherwise I get major tearing).

As a final consideration, I am getting noticeable coil whine from the card after I quit to the credits screen in heaven.

What do yo think? Bail out while I can?

BTW, awesome guide. Thanks to SeanPoe!

I just assumed he didn't have the load at startup box checked because of his question. Sometimes even with load to startup on it still doesn't actually send the OC to the card until you hit apply again.

If you had bought the Asus non-top, i would say that that's just the nature of things and it would be somewhat unethical to send it back, but with the TOP version, you technically paid for a card that's supposed to hit around 1242MHz. Asus really dropped the ball here with the TOP models, they're not binned properly (or at all), and they're selling a product that's not capable of performing as advertised. I would send it back for a replacement or a refund if it was me personally.

I have a Reference Galaxy GTX 670, managed to get this overclock. Mainly play Battlefield 3, working out BF3 settings so I never go below the 60FPS then will switch on Adaptive V-Sync (works well) this will then tone down the amount of activity my card does and hopefully prolong the life of the card!

My boost will go to around 1293 to 1306 in Battlefield 3, hovers around 65-70c (Adaptive V-Sync off)

I have played with clocks for a while this night, not using the Guide tonguesmiley.gif
GB 670 OC

600

My monitors are 1680s so I had to test in windowed mode but that way it uses 1920/1034thinking.gif
This is at +95(1215max boost) and +600 Memory. I need to test for a longer period of time to see is it stable enough.


Just a question? At +100 my max boost is 1227, at +95 its 1215. Is it normal. Temps dont go above 65.
And why are there different max power targets? Mine is 112%. And I have seen 120ish. cavalier9976 is at 122%.

is 41 degrees C OK as an idle temp?

That seems pretty high. It won't cause any damage or anything but it might be worth investigating why it's so high. Are your load temps still under 70C? What's your ambient temps (room temperature)? What's your idle fan speed like? What case do you have and do you have good airflow?

I still haven't figured out why the offset doesn't linearly change the max boost. Even without getting throttled it's not linear. I tried to figure out a pattern, but it seemed pretty random (sometimes 1 offset = 1 MHz, other times 1 offset = up to 5 MHz change). For example, you're seeing a ~2.4MHz change per offset. So to answer your question, yes, that's normal.

Presumably the max power target is set when the GPU chip is made. It's really the only explanation why GPU's from the same manufacture and same exact model number have varying power target ranges. Though, it does seem that each model actually has it's preferred power target range (like Gigabyte's are mostly at 111%, Asus' are mostly at 117%, Galaxy's are mostly at 122%, and EVGA's are mostly at ~132%). At least that's the pattern I've observed. So i think it would be more precise to say that the maximum power target is set when the GPU chip is made and then manufactures can choose their own maximum (this is also my theory for Kepler Boost too).
