Post Your Stable Overclocks! (Radeon HD 6770M)

I'd like to get a general feel of how far this card can be pushed while maintaining stability.

 

i can't go above 800/960
others have gone to 850/950 comfrotably
furthest i've heard is 900/1125

 

At 850/950 I was seeing some artifacting after gaming for awhile so I dropped the memory clock to 900. Right now I can get a perfectly fine 875/900 but I'm just getting started. These clocks bumped my WEI from a 6.9 to a 7.1 .

 

I can get 850/900 with no artifacts detected by atitool.Temps go up to 73 with the 2nd fan preset and hover around 70 when the 3rd fan preset kicks in.
Have yet to find a program which will let me control the fan speed of this laptop :/

 

I'll post it in here as well.

Ok i bumped up the 6770m's voltage to 1.055 and got a stable OC at 925/1050.
Max temps ~78
A little bit and i could have reached 1GHZ on a mobile gpu!ARGH!

 

Is there a preset temperature that the gpu/cpu should never cross? if so what is it?

 

I would say that under 85 you are fine.That said my previous gpu Nvidia 8600mgs reached 95 but that was due to the defective chipset.

 

I can handle 880/985, voltage 1.055, and no artifacts with ATItool. My Temps are around 70-ish. Soon it should be lower since i ordered a cooling pad for exactly this reason.

And just curious, what driver version is everyone using? And for that matter what is the latest released official/custom driver available? I'm using driver version 8.830.6.2000.

 

noob question... how did you guys change the voltage? I don't have the option with MSI afterburner and I can't find a new version of ATItool

 

Get SaphireTrixx and i use atitool only to scan for artifacts and test gpu temps. not to oc.

I am using the 11.5 AKA the 8.850.......

 

I've been running atitool's artifact scanner for 20 minutes now, and so far no artifacts I used sapphire trixx's tweak utility to OC the 6770M to 825/950, hopefully this is stable.

Temperature's hovering between 72C-73C

how can you rest gpu back to default? my default clock memory shows 216mhz in gpu-z that cant be right smh I used sapphire trixx to oc

 

What's the maximum safe voltage? Trixx will allow me to push it to 1.1v but I'm really not sure how safe that is.

 

A sound advice would be to never set THIS card to 1.1v because it is almost certain that you will fry it.

There is no maximum voltage,it all depends on the cooling.For instance,mine reaches ~80C when at 1.06v so i wouldnt go passed it cause i dont want it reaching temps over 85.

Sorry to intrude on the topic, but can you overclock with the 6100 series or just the 6000 series?

 

you can overclock both of them.

i get 3dmark vantage: P8487

Result

 

how did you overclock your dv6t 6100? when i use saphire trixx it doesnt work. all clock, and voltage settings show zero and cant be changed.

3DMarkVantage : P8628

 

Hmmm Sapphire won't let me change anything...I enter a number and it just goes back to 0. Tried Afterburner and the same thing. Any ideas? I'm not a gamer I was just playing around with 3D Mark and wanted to see how high I could get..lol

...yeah just realized you can't OC the 6100 series 6770M.

 

Any more info? Can the dv6-6100 series really be OC'd?

 

it would be nice to know how much increase in FPS all of this overclocking is yielding while gaming.

 

2-3 maybe? lol

maybe 10-20 if you're already getting 200fps

 

I assume you modified the .cfg file ... right?

My [a]Musings

 

Hello there fellow 6770M-ers...here are my scores:

3DMark11 Basic:

@ Stock clocks: P1492
@ 850/900: P1758

The driver used is 8.830.6.2000, the latest official drivers available from the HP site. Overclock was done using MSI Afterburner + the .cfg mod needed to make it work, just like in the above post.

Gonna try and push it some more, however i would like you to tell me where did you get any newer drivers than mine i suppose newer drivers will pump my scores and fps, right?

 

You can get modded Catalyst driver by asder00 from Guru3d forum. Do not remove HP AMD driver, just install it on top.

You can use DNA driver or Xtreme-G driver too.

Links: AMD Catalyst 11.8 WHQL (8.881 July 28) | DNA-AMD GFX 11.8.3-prev | Xtreme-G |

 

Kudos to you, thanx! Using the DNA 8.880.8.0 (11.8.3) i got 50 more points on 3DMark11. I know, not much but...oh well. My 6770M is now recognized as 6700M Series, not that i mind though. Going to explore additional ways of squeezing every drop of performance possible. I'll also order a cooling pad (thinkin of CoolerMaster Notepal X2) to keep those degrees down a bit. I want to get into the 1900's at 3DMark11, but i suppose that's not possible just by overclocking...

 

So here it goes, P1901 on 3DMark11 with 900/950 and 1.051V, using TRIXX. If i try it with 1.050V, it displays artifacts and then crashes.

I am getting 900/1080 and can push it slighty more on the core and memory.

Better still is if I drop the core down to 600, I can push the memory all the way upto 1200 (can only push the memory this high by dropping the core speed). And running the 6770M on battery at 600/1200 is very nice with turbo disabled on the CPU.

 

I have found that rising the core brings better performance improvements over memory.

And I'm sorry to report to everyone that using only one bench for stability just won't cut it. I had crazy clocks getting over 1900 in 3DMark11, but when I gamed on Just Cause 2 it would crash.

In order to find super stable clocks...I launched FurMark, RTHDRIBL and Heaven 2.1 benchmark, at the same time all at max settings so that they would stress the memory too (except resolution so i can see them lol) and I watched my overclocked 6770M fight to the death.

That said, the best way to find perfect clocks is trial and error by gaming or by using the in game benchmarks.

No benchmark alone will stress your card to the absolute max, not even FurMark. (I had stable clocks with FurMark that failed in games).

 

My GPU temp is 86C after 30 mins of Furmark
825/950
Is that ok?
Im a noob at overclocking...

 

86 is too high.
Set your HP Cool Sense to Coolest Mode. This stops CPU turbo boost. Turbo Boost yields almost no performance gain in games since this laptop's bottleneck is the GPU, and will drastically increase temperature. So setting Cool Sense to coolest should yield you ~5c of temperature loss.

 

After testing on the witcher for about 3-4 hours, I found 840/1000 to be stable at stock voltage. This is of course under 11.5b since other drivers produce wierd graphical glitches for the witcher 2.

If i set the core clock to 850+, the GPU will force shut down and restart for no reason every 20 minutes or so in game, causing 2 second freezes.

 

Im getting stable results at 860/960
Any higher and I get blue screen.
Still not sure if it is worth overvolting?

 

Well I guess it depends on each card specifically. Mine reached 800/950 at stock voltage.

Right now I'm at 880/1050 with 1.051v. Slight overvolt but useful.

So if you ask me "Is it worth overvolting?" I''ll say hell yea.

Cards get fried by temps, not volts.

 

yo johny, what drivers are you using.

 

Latest official HP/AMD .3000 driver and on top of that, DNA 11.8.3-prev.

 

I went to their website, and it said something along the lines of x64 bit systems wont allow modded drivers to work? whats your experience with that?

 

I can use 870/970 without any crash on BF3 Windowed mode Atm.

 

See, here is the strange part.

11.8.3 DNA install perfectly and they do not cause any problems. Don't worry.

The newer version though, DNA 11.10, installs normally, but when you restart, you have no video driver.

So my advice to you is to download 11.8.3.

I'm not downloading DNA 11.10 even though I wanna play BF3. I am keeping HP's .3000 and then I'll install over it either an updated modded Xtreme-G driver (like DNA) or the official AMD 11.10.

 

Oh and something else I found out. It will sound funny but...if you want to check if your card has stable clocks.... load a youtube video and try it at diffrent quality settings! I supposedly had stable clocks, but when I would go and watch a video, the driver would stop responding. (I suppose it has to do with hardware aceleration)

I lowered the clocks a bit and all is fine now.

 

Max I can get is a stable 850/925 @ 1.053v. I can go up to 1000 on memory and play a game for hours, but as soon as I get into firefox it will lock the system after a few minutes. Kind of strange, but goes well with the post above me.

 

Max I can get is 860/980 @ 1.051v.

So I guess we have a new standard benchmark in the neighborhood. Flash playback on the net. (FYI I experienced it with firefox too)

I think that now everyone in this forum has to reconsider his max clocks.

Using higher clocks (The same clocks that were very stable in games), I get artifacts (yes!) in youtube videos (if way too high I get a short freeze and then full display driver recovery)!

And always remember. Pushing the core brings higher results than memory. So if you can (this goes out to everyone) lower your memory and push the core.

 

You know, I rarely go to you-tube. I get the lock ups just in regular web pages. No flash, no scripts...nothing.

I'll get out of a 3 hour game of F.E.A.R. 3 at its highest settings, go to the bathroom, get a drink, and then get into the web and it locks on me. Absolutely its clock related as it never happens with the clock set lower, and I've tried it with higher core and memory independently and get locks when its set past my stable range, regardless of voltage.

From a back in the day overclocker, talking p4's and phase change units, its weird as hell when Firefox is your stability test.

 

AMD PowerPlay is most likely the culprit. Try disabling it.

 

I know it doesn't make sense about firefox being one, but it's a fact that I got a stability test here. I knew it the moment I saw youtube videos artifacting and there's no denying it.

And yes, my core does have a "ceiling" regardless of further overvolting, too.

Which drivers are you using? I'm starting to think that it could be a driver issue. At least for me, that I'm using modded ones (DNA 11.8.3). Soon changing to 11.10 Mobile, gonna test it with them too.

 

Already did, didn't make any difference.

My core has a ceiling absolutely. Additional voltage past 1.053v will give it some extra time, but it always locks up if its past 850. However I did notice that bumping the voltage (1.059v) lets me raise "game" stable memory clocks to the 1050 range without a problem. Its just that damn Firefox that gets it in the end. Temperatures while gaming max out around 65-70c while sitting on my cooler.

Drivers that I've noticed it on,

-Original HP's
-11.5b
-11.8

If you notice anything different on the 11.10's let me know. This has to be some sort of strange software bug. 3 hours of near max gpu usage followed by a drastically reduced load and a lock. It just doesn't make any sense.

 

Downloaded and installed 11.10 Mobility over the latest HP one (.3000), didn't notice any changes. GPU-Z does not show the 11.10 driver, it shows the HP one. (?!)

Same problems exist, flash artifacting etc. Same 3DMarks, too.

So either no improvements, or the driver didn't install. I have to point out though that it seemed an OK installation. No problems there.

 

Installed XTreme-G 11.10 over the stock HP. They install and run fine BUT they remove overvolting. Guess I'm going back to DNA 11.8 cause DNA 11.10.1 do not install on my laptop. :S
