g73 GPU Overclocking

Hi folks. I recently went through a laptop purchasing phase; bought and resold two systems before settling on a g73. The last system I had was an iBuyPower which also had an hd5870, and it got really good overclocking results. I was able to use "Overdrive" in the Catalyst Control Center and the auto-overclocking went to 850/1100, which gave a very noticeable improvement in performance. I wanted to play around with overclocking my new g73 too, but now the option isn't in the catalyst control center, even though it is the same version (I even reinstalled to be sure). I tried GPUTool just now, but for some reason it isn't showing a temperature or fan reading for my GPU, which is a bit disconcerting, since it certainly did for my last system.
What's up? Is there some Asus software that's locking down CCC and not giving access to the GPU temperature sensor? Is it more fundamental than that--some kind of hard-wired BIOS setting?

 

Most likely the Asus stock vBIOS causes this.

You could give Ziddy's vBIOS v3 a try. Apparently, that fixes all problems to do with GSOD, etc as well.

 

I'll check it out--thanks for the info.

 

GPU tool is not meant to support mobile cards. There is one specifically for the 5870 cards and it works with the mobile version. Though I do not recall if it shows gpu temps.

Best thing to do is get the correct AMD GPU Tool for overclocking the card (as the overdrive does not work anyways even if you enable it) and use GPU-Z to monitor your tempatures.

It can log temps too and that is important so you can see what your temps were while playing a game or something demanding like that witch full screens and covers the GUI for your monitoring program.

 

Just an FYI, there is a huge Asus Gaming Notebooks forum with this information readily available with the 30 seconds it takes to use the search function.

 

I'm kind of new here and I actually had not noticed that there were brand subforums--my bad and apologies for wasting your folks' time.

 

Hindsight, you posting maybe better. Currently the Asus Gaming Notebook forum has become overrun by a few angry G73 owners, wading through all their few complaints repeated constantly isn't fun.

You should be able to download the AMD GPU Tool from Techpowerup

Just use MSI afterburner, AMD GPU clock tool is terrible.

 

Seconded. AMD GPU Clock Tool rarely works for me.

 

Is there actually a difference in the way that different programs overclock, or is it just the tools available for checking stability that differentiate them? (i.e., since Catalyst gets the job done for me, what should entice me to try GPU Clock Tool or MSI Afterburner?)

 

Both.

I'm pretty sure that MSI Afterburner and GPU Tool use a similar system to raise the clocks on the cards, etc, but AMD GPU Tool uses a different method, I think. I think that is the reason why on the same drivers and same card, one will work when the other doesn't.

GPU Tool also offers an inbuilt stability test which is actually quite useful for an overall stability check (use Furmark or similar to properly test), and another handy little gadget which raises the clockspeed automatically until it encounters an error.

 

if u want to OC , why not flash the vBIOS using raedon BIOS editor? U might unlock powerplay(downclocks GPU) and overdrive(allows OC).. there are vBIOS's in the GSOD thread which is unlocked with overdrive and have some powerplay which u can edit..

 

Hm... ive found no problem with my g73 i left everything stock and.... suprise nothing is messing up. People have a nasty habit of taking something great and trying to make it better and ruining it in the process. If you have a Lamborghini dont try to tun it into a F116 jet fighter.

 

Yeah, I tried vBios v3, which let me use CCC's Overdrive function, and my card seems pretty happy at 850/1190, although it greyscreened once in Warhead.
I think you're generally right, Lannik--at the very best I'm looking at perhaps a 20% increase in performance, so it is more an interest in experimenting with overclocking than a practical desire to see massive performance leaps.

 

those clocks are too high.. lower the core or u'll burn the card out.. i'd do 800/1100 at most but really u don't need to OC now.. its later when the card gets older and games become harder to handle on high details..
