Post Your Stable Overclocks! (Radeon HD 6770M)

You can't overvolt starting from 11.10-preview1 driver and over.

 

Would you care to explain why is that? And does it mean that for every release from now on there won't be any overvolting?!

 

I'm not Andrew the catalyst creator You should ask him instead.

I've tried several version newer than 11.10s. No overvolt.

 

So unless I have compatibility issues with BF3 (which is the main reason I wanted the 11.10)...I ain't switching.

 

Hi Guys, Johny,

I installed the 11.10 AMD mobility drivers ontop of the 8.830.3.6000 HP official, and am experiencing flashing artifacts that appear about once a second in BF3, and in Uniheaven 2.1 (Default settings, with Tesselation turned on by default).

Have you guys encountered this problem on the 11.10 drivers as well?

I'm wondering if my gfx card is faulty or of its a driver issue - If you guys havent encountered artefacting on 11.10 then its probably my card and I should get the laptop RMA'd yeah?

Cheers

 

^ just a driver issue.

 

ah thanks for the info, u experienced the same thing too i guess?

cheers

 

my core clock is 850 and memory is 900
what should shader clock be at?

 

^ shader clock slider only available for Nvidia cards.

 

8.830.3.6000 HP official? Check again mate, it should be ".3000". As soon as I understood that I can't overvolt with the 11.10's, I dumped them :S Which version of the 11.10 driver did you use? AMD Mobility? DNA? XtremeG? They are different.

 

AMD cards use different architecture, and besides shader clocks automatically overclock with the core clock, cause they are linked. I think the ratio is 2:1 for shader and core respectively (at least for Nvidia 8xxx series that I know). So no need to worry about it.

 

Ah yep - sorry i meant 8.830.3.3000

Yeah, along with the flashing textures in BF3 / Uniengine, I cannot up the voltage when using AMD Mobility 11.10

Which version of 11.10 did you guys not encounter the flashing textures with?


Update: i removed 11.10 using driver sweeper, then reinstalled HP drivers + 11.9 mobility, and BF3 flashing issues are gone - so it must be a driver issue then

Uniheaven still exhibits same flashing artefacts in 11.9 tho, so yeah, probably a driver issue since BF3 flashing is now fixed with 11.9

 

Heaven benchmark exhibits those flashes in every version that I've tried.

 

thanks johny.

 

ah thanks johny +1,

thats defniitely useful information to know!

im sticking with 11.9 since i can run BF3 with no artefacts. didnt like running the official HP drivers since i reckon they must be old (11.3 or 11.4 from what I understand)

do you know if anyone is running a version of 11.10 successfully with no artefacts in BF3? AMD mobility 11.10 (whql, and preview 2s) I definitely had issues with

Cheers

 

No, I don't...so if I were in your position I would simply wait for the next wave of drivers. Btw, how is performance with BF3? I am going to get it and I would like to know how it performs.

 

i think im the first to have a 7690m and post in here . Let me just say that a 7690m is pretty much the same thing as the 6770m, not that much of a performance difference. However, due to the 7690m being a "rare" and new grahpics card, every amd driver i try to install fails on me . Some work, but i cant really update to the newest versions and all that(which may not be a bad thing since you cant overvolt in the newest versions anyway). Im overclocking mine at 850/1030 and testing it for now, ill come and post back later my results later after playing bf3. Btw, most of you guys said your gpu roof was around 840 and would just crash if you played something like crysis 2. Likewise, mine is around 850, my voltage is 1.060v and regardless of how much i increase my voltage, the max i can increase the 7690 without crashing is still 850. Geez, im going 1.060v without any cooling pad, im an idiot

 

Highest I can go is 800/950, I get BSOD's if I go past that.

 

Either my laptop is Jesus or my driver is messed up.

 

Nice clock bro.

Try GPU Caps Viewer - oZone3D.Net.

 

I got it set at 800/1000 with no issues, using the latest HP drivers.. haven't check for "artifacts" don't really know what they are but to my eye, bf3 looks beautiful and I run it at 35fps average, max 60fps

 

Alright, figured it out. If PowerPlay was disabled, it would force the minimum profile, even if it was told to use higher clocks. Enabled PowerPlay and I got it pretty stable at 825/1075/1050mV. Overvolting doesn't help at all.

 

EDIT: posted in the wrong thread. admins, please delete!

 

Just took my first dip into OC since my old 9300M GS
(38 months at counting)

As this is day one, I haven't done much multi-hour tests.

I have set 875 MHz core, 1000 MHz memory, and gotten through 3DMark Vantage (~8400 score), Unigine Heaven, AND a 1080p Youtube/Firefox test without anything unusual.

I used a Zalman NC2000 cooler, max GPU temp was 73 degrees.

I did experience that flashing effect in the Heaven benchmark, but its always done that. running in Windowed mode or OpenGL made it go away.
It seems to be a common fullscreen issue in a few games.. for me it always affects The Witcher.

I'll have a pretty good idea how stable it REALLY is after a 12 hour SWTOR run.

 

Hmmm.. Running a few .flv players seems to kick back to default clocks when 1 GHz memory is used.

Probably not liking that setting.. but then again they call it a GHz barrier for a reason.

BTW.. Why should Powerplay be disabled again?
I have it enabled until I hear a good reason why not.
I'm using the 11.12 drivers for SWTOR, so its not as if I could overvolt anyway.

 

Yes, 7690M = rebranded 6770M. It even has the same o/c ceilings...this is a very, very good card. Btw 1.060 is overkill. Try 1.055. I'm on 1.054 with 860/1060.

 

hiii. I have a DV6 6cxx series, w8/ 7690m XT 2GB DDr5, and intel i7 2670qm
here is my scores

3dmark06 stock drivers, stock clocks:

I repare in one thing its very interesting, All knows this Brand new graphic card 7690m XT is a rebranded 6770m with same clocks (according to GPU-z) but i'm able to overclock more, and Default config get more 3dpoints! i thing something is missing in our know about this card! the 6770 are able to overclock its 900/1000 with voltage change, in my GPU, its not needed!
Maybe its not the same same card! i mean its the same but with certain improvments. not?

 

Yes, 7690M XT can be oc without changing the voltage. someone in my local forum managed to run 3dmark11@940/1000 without voltage mod.

 

now with standard resolution thing
overclock 900-1000:

For those who still confuse about the new rebadged gpu.

HD7690M XT = HD6770M
HD7690M = HD6750M
HD7670M = HD6650M
HD7470M = HD6490M

 

Is it possible to do an clock on this card without raising the voltage?

- Sott.

 

yes.
start overclock slowly. if you want first memory after core and do maybe 5times run sm tests on 3dmark 06. only sm test to find for artifacts. if sone red bleeps appear on screen press esc and downclock
this method i think its better than artifact scanner from att and other

 

Right now, my stable OCs to be able to play BF3 are 780/850. Over that (800/850) BF3 crashes right at launch. Do I need to increase voltage to OC over 800/850?

Also, the video capture set to 1/2 frame on MSI Afterburner is in black and white and also has the right margin overlap on the left margin from the left. Google results say it is probably a GPU driver issues, but I am running the latest HP drivers.

 

I have run bf3 with 825 and 950 clocks without issues, except of the crashes I have with any clocks I tried before.

 

And have to say that latest hp drivers are probaably the most stable but performance is not as good as with newest ones, about 15-20%

 

OC 825/950 seems to be the right one, haven't had any issues with BF3 or youtube

 

825/950 without any voltage raise?

Again, thanks guys.

- Scott

 

stock voltage

 

OC/D to 825/950 now on stock voltage. The temp never passes 72 on the GPU sensors and the CPU is laying below 80. How can it be that my FPS went down (BF3)? Still the same GFX settings, same drivers, etc..

Im now getting FPSs aorund 30-40 on everything low..

- Scott.

 

Anyone else experiencing freeze issues with MSI Afterburner while playing BF3? The FPS is decent with low-medium settings, but it hard freezes mid-game during the first few matches. I have to shut down and reboot from the power button to "fix" it. I am running 850/900 on stock voltage. What could be causing the freeze?

Will try out Trixx and report back.

 

increase your core voltage a bit (maybe just 5mV) and try again. your overclocks are not stable enough i guess.

 

Actually,

7690M XT = HD6850M as they both found only in ENVY series.

and

7690M = 6770M.

 

Okay, super nice clocks! So you have 11.12 and you're able to overclock? I thought that anything from 11.10 and over was not able to O/C.

Also, which version of 11.12 is it? Mobility? Download link please.

 

Nope.

7690M XT = HD 6770M

7690M = HD 6750M

 

Ahhhh yes, my bad. They're actually faster versions of 6750M and 6770M.

So wait, HP downgraded the GPU for the ENVY's?

 

Nobody will notice

Out of curiosity , what is your 3DMark06 score for your sig laptop ?

 

i think 11.10 and newer drivers have removed the ability to overvolt, but you can still overclock.

 

Never tested with '06, it is out of date and doesn't fully utilize the tech in the new cards...

On 3DMark11 though, I scored 1800.

 

Okay, tested with 3DMark06, result 14119 points.
