How do I overclock an Asus Nvidia GTX 670 DirectCU II?

I installed the ASUS GPU Tweak program and I'm using an AsRock Extreme4 z77 mobo.

I've no idea what to do? Any help is appreciated.
 
turn up the power limit to max and raise the core clock. try raising it 100mhz and then go up in 15-20mhz increments. run a stress test such as furmark or run folding@home for half an hour and if its stable and nothing bad happens, raise it up again and repeat until stability is not achieved. and thats your highest overclock
 
I recommend finding a youtube video on the subject.

A video is going to be a LOT more descriptive, and thus a lot more helpful, than what we could give you through words alone for something like overclocking a video card. That being said, don't expect too much out of it - Kepler doesn't overclock very well at all.

Thanx guys for the information! I probably won't overclock anytime soon until i'm completely sure I know what I'm doing anyway

OMG! that is so nice to hear for once! LMAO Read the stickies in the forum - great info and gives you a good handle on basic concepts to start you out
 


thats total bs. my 670 from gigabyte can never go above 1300mhz, yet the highest temps i can get is 60c.

Well - not sure what branding you are using or what OC software, but I have seen proof of them stable over 1300. *shrug* dunno - maybe limitation of your card or software. Highest I have seen is 1364 - so far....

And on air cool have seen them hit 80+ on load - but again - depends on your cooling solution and ambient case factors, external exhaust or internal, etc... many variables can all play in. But certainly not BS... *finger wag* lol
 
im using afterburner, the software that asus makes their gpu tweak off of. i dont use case fans and im running a corsair 550D which is supposedly hot as hell.

ive seen higher with 1450mhz on a msi power edition with voltage unlocked. and it still doesnt run above 70c.

i have never seen any reviewer ever get thermal lmited with their kelper cards. they are always voltage limited and silicon limited. so basically, kelper being thermal limited is total bs.

For you - all of that may be true - I have seen differently - hence the forum - lots of experience all gather in one place. As you see in the statement, I specifically said OP limitation - not limitation of chip or card. Unless you are omnipotent, there are situations, variables, and realities outside of your experience. You also stated not possible for it to go above 1300 - i know that is not true as well, and is verifiable. This OP is just heading into world of OC, and therefore may not have full grasp of what can happen or have a case tweak to handle. Gearing my answer toward a newbie certainly is no reason to denounce nor claim not possible. In other words... Chill man... relax... kinda coming off hostile - it's a big world out there

not what I said - I said I would not advise OC on a stock. Two reasons: 1) The stock cooler on his card is an internal exhaust - depending on HIS case setup, this may cause other issues 2) Generating additional heat does put additional stress on the card, shortening longevity - basic of OC - the lower the temp the better. Upgrading cooler will address both. I never said not possible or never do it - I said I wouldn't advise
 
dude, i have a corsair 550D with no case fans. the gigabyte windforce 3x dumps all of its air inside the case, yet i never reach above 60 unless i max out the clocks and run folding@home for a week straight. and in general, my case has worse airflow. unless he has IDE cables flying every where, you arent going to get any worse airflow than what i have.

 
so if you are saying that overclocking with a stock cooler isnt recommended, that would mean every single aftermarket solution out there is basically pointless when they can clearly perform 10 degrees or more than the reference cooler and at the same time become 10 dba quieter.
