Graphic Cards Overclocking HD 6770

i bought a new graphic card gigabyte 6770 , it was only availaible in my budget

now its slightly underclocked i.e. core 775 Mhz , memory 1000 mHz

AMD over drive contains an option for overclocking upto 960/1200

i want to know if i overclock it will the warranty be voided and upto wat limit i can safely overclock it ?

and what are the consequences if there is any ?
 
As far as the card isnt physically damaged or overclocked over its extent, warranty doesnt void.

Before proceeding, post your system specs and esp. your psu. It all depends on it.
 
#[member='nikhilkdipsar'], don't worry mate, warranty will be not be void. In case the card givesup, just don't tell anyone that you have OCed.

The manufacturer can't determine, whether it has been OCed or not.

Is that the Coolermaster extreme power 600W? Its an overrated unit and not something i would overclock on.

Do you want to overclock because you're suffering from poor performance? I would suggest first upgrading your PSU and maybe getting a better card.

If you just want to experiment with overclocking, then use something like Furmark (http://www.ozone3d.net/benchmarks/fur/) to stress test stability and monitor temperatures. Increase clock speeds by very minor increments of 5 or 10Mhz at a time, and each time keep testing stability and temperatures, till you get a hang of things. You can overclock either the core of the memory till you get an idea of its limits. I cannot stress this enough but if your overclock isn't stable and temperatures aren't in check, you will kill your card eventually.

If you want to keep it as a permanent overclock, always have a safety margin ie. scale back clocks by a couple of mhz from the maximum stable values you reached.

Yes they cannot determine if a card has been OC'ed unless there are visual signs of damage, but you should not abuse the warranty system or encourage others to do so.
 
#[member='Jarod'], thats true mate, but OP is too paranoid about OC and warranty, so i suggested him that. My suggestion is fair, i don't think OP will OC it to that level, where the chips gets fried

yes it is extreme 600W and bro i cannot upgrade my PSU

card is ok on games i play but i want to overclock because i m getting bit poor performance from my expectations

how to use that furmark?

here is the pic of my amd overdrive , shud i overclock from here or i use msi afterburn?

Look even I am in agreement with #[member='Jarod'] over this one, the Cooler Master eXtreme series is not good enough for over-clocking due to the following reasons --
  1. Efficiency, the rated efficiency of the Cooler Master ~70% under normal loads at an ambient temperature of ~35°C. If you over-clock your card this efficiency will take a further nose-dive.
  2. It has a bad enough reputation, you do not want to test from where it got this reputation.

What was your expectation? What games are not performing upto your 'expectation'

Better that you use the MSi Afterburner software Sire.

Hope this helps, Cheers!!

may be to run BF3 and Metro 2033 simultaneouly switching both (alt+tab) every 10 min and complete a mission all with a min FPS of 80??

isnt it fair enuf??

on a serious note, the performance inprovement, unless u can see a considerable change (from a lagging game to sooper smooth), is just a myth for the naked eye, unless u are much more than a gamer who play for fun.

Enjoy the card on stock without much fuss and let it live its age.

i got no money left now , all spent in buying GPU

my max resolution is 1600x900 , m framing in "counter strike global offensive " not getting 100 stable fps , my other frnd with AMD 6770 playing at constant 100 fps

i dont want to overlclock it to extremes , just appropriate so that i can play well at my resolution

also when i switch screen to desktop and in game framming starts for some time

Sire what is the complete configuration of your RIG and that of your friends RIG?

Stable ~100fps is not a measure of smooth gameplay Sire, you need a stable fps of no more than ~60 to experience proper gaming. What tool are you using to measure your fps?

Cut down the sarcasm please, that was not required.

Maybe something is holding up OP's performance, even I have an HD 5770 [a base HD 6770] even now it performs pretty well @stock settings in games like The Witcher 2, settings are high at a resolution of 1600 x900.

i donno about his rig , and i m using developers console command to see the fps insideof game...and i can feel that game is not running smooth

Okay I think your RIG should be enough for gaming Sire. Do not use the developer command console and run the game.

Do send over the details for your friends RIG as well, it will help diagnose any problem why your system is performing slower.

You can start by over-clocking the graphics card but don't become too greedy. Cheers!!

i ll post his rig details wen he comes online

More importantly which Catalyst version are you on?

Also, I think Couter Strike Global Offensive is in beta mode, run a game like Crysis 2 OR Metro 2033 at medium settings to test your graphics card.

i was playing Mafia II and wen i switched between game and desktop and back to game , it started framing , i played Dota 2 , CSS, payday the heist , l4d1 they r running fine.

I was not asking about the About of the AMD Vision Control Centre, to find out which version of the driver you are using --
  • Open Catalyst Contol Centre / Vision Centre
  • Go to the Information tab, click on the same.
  • Select the Software sub-option, that will tell you which driver you are running.

If it below v.12.3, you need to update buddy.

Also Mafia II is a really heavy game, my friends GTX 460 1GB used to struggle to run it on high settings @full HD format. Even my HD 5770 1GB frames in heavy scenes and ironically I have the same resolution as yours 1600 x900.

Okay here is the latest edition for download --> http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx

Hope this helps, Cheers!!

i overclocked it to 850 /1200 by amd overdrive

i was playing L4D1 , after some time when i was in game, my PC crashed/hanged , does it mean it cant be clocked to 850/1200 (its not that high) ,or i shud use MSI afterburner or any other soln to it ?
 
Clearly, the card is not getting enough voltage.

Default voltage for HD5/6770 at 850/1200 is 1.125V. So, just download MSI AB, post your voltage, we will help you after you post your voltage. At 775/1000, the manufacturer must have reduced voltage to keep the temperatures under control. Hate to break it to you this way, but I think that maybe purchasing a downclocked card was not a good idea, because naturally, the manufacturer must have cheaped out on components. But if you get lucky, you could be able oc it at stock HD6770 with a voltage bump at stock i.e 1.125V. But don't expect it to reach much, past that.
 
#[member='GameR1120'] , Please do not suggest overvolting a GPU to a new overclocker, unless you are willing to buy him a new GPU.

#[member='nikhilkdipsar'] , Please do not touch voltages at all for now. I guess you did not follow the instructions about moving in steps and testing stability but just set it directly at 850/1200? Why?

If you think overclocking works like that, please read this thread first and see what happens - http://www.techenclave.com/topic/512963-help-new-pc-showing-no-signs-of-powerwont-turn-on/ . GPUs are even less forgiving.

You can try MSI afterburner, it has furmark inbuilt. It might work with your card if its following the reference design. Run furmark and if it runs for atleast 15mins without artifacts or crashing, your overclock is stable.

Since yours is an underclocked design, its highly probable that they are using lower binned chips, so do not expect stock 850/1200 speeds. Most of the time the GPU core can scale fine, but the RAM will be lower speed stuff. So start with finding the RAMs limitations first.

One more thing. Is your friend running the same Gigabyte underclocked GPU as yours, or is his clocked at reference speeds?
