Overclocking the Radeon 6770m in the dv6t 61xx

Yes, but still have no options to rotate displays.

 

...it's on the same screen as the resolution.

 

it is not...appreciate any help. screenshot attached.

 

looks like the world is stumped along with me.

 

hey guys could u check ur heaven 2.5 benchmark score oc'ed..

 

"theexception" this is an overclocking thread, please search the forum those questions or start a new topic and keep this thread on topic, please.

 

I just tried to OC my 6770m, I followed the directions, I think it worked (got a 3dmark11 score in the high p1700s)

But now when I open MSI Afterburner it show's I'm still on stock clocks, even after I put them up to 850/900 again and hit apply, when I re-open the software it says I'm back to stock... And when I look at that graph thing on the side it says my max core clock is 400... So is there some program or way to 100% accurately tell what the clocks are? I know my AMD drivers are slightly outdated (month or so, just one version) but does that really make that big of a difference?

 

Hmm... I downloaded GPU-Z and if I change the clock settings in MSI Afterburner apply and close it GPU-Z says that my clocks are 850/900 (what I want) but when I re-open Afterburner it says they're stock again, and GPU-Z confirms. What seems to be happening is that MSI Afterburner is resetting to stock every time I open it. I guess... Any surefire way to know?

 

Never mind, I answered my own question. I reset the clock to stock and benchmarked it, p1500s, OCd it (even though MSI Afterburner didn't seem to think so, although gpu-z did) it scored about 1800. That speaks for itself.

 

afterburner can be a bit weird sometimes

but usually after u set it and restart the laptop it will stick. you just have to keep the process going in the background

 

Well I was playing black ops and the display kept freezing, flickering, and reloading. Couple times later and I got the Blue Screen of Death saying something about display adapters. Windows wouldn't start so I had to do system restore, now I think it works again... It was obviously due to the overclocking, but all I was doing was 850/1000 (afaik) and I was getting 60 fps before it crashed in Black Ops on the Vorkuta level. When I tried again with 850/1000 just now, I was getting 25-30 fps in the same level, which is basically the same as it was when I did it on stock clocking. ? What kind of a difference is normal in Black Ops Singleplayer? Just a note, but I get the same FPS whether the textures are on Extra or Low, which is strange. But yeah, no more crashes.

 

Oh **** I think I killed it... I just did a 3DMark11 on it with 900/1000 clocking and it scored P912!!

912!!! CRAP!

Ummm.... What can I do.... heeeelp....

 

If you had a clock that was unstable, what in the hell are you doing clocking higher than that? Seriously, stop.

 

restart your laptop and run the test again on stock clocks lol

 

What, no link to the score?

 

I didn't over-overclock it though... It was at 850/1000, plenty of people here have gone higher than that. If you want a link to the thing I'll run the test again...

EDIT: After reinstalling the display drivers (AMD) and rebooting the computer, the GPU scores in the p1500s again, at the same score it was before I messed with it.

And then you went to 900/1000, for God knows what reason.

 

900 core is like asking for a burnout if 850 was bad...

 

Oh whoops, that was a typo. It was never 900/1000.... Well at any rate Black Ops hangs with it at 850/900 too (I closed it this time before BSOD) so I'm going to try 800/900 maybe and see if it still does.

 

why are you O/C'ing at all for black ops??? it runs fine at 50+ fps at stock clocks on max

 

Wow, I stand corrected. I was against overclocking a laptop GPU. I still won't overvolt, but I just went from playing Dead Island at 1366x768, stock, medium settings at about 45 fps to playing it at 1920x1080, high settings except shadows, overclocked at 850/1000 pegged at 60 fps vsnc and it doesn't get any hotter than usual. No artifacts or snow, this 6770M overclocks like a beast and almost doubles framerates. I have never seen that happen in my desktop gpus, I think HP really went on the conservative side and clocked the gpu too low, especially the memory (can go 1000mhz with no additional heat or voltage). This chip was obviously made to be clocked at at least 800/900 in my opinion.
I got the 2GB 6770M (came with the 1080p screen model), so maybe this one is newer and clocks better.
At first I didn't see a big difference, found out that when on battery power the overclock doesn't happen, only when plugged in.

 

ok. got it. thanks.

 

A question for the experts:

I noticed something when running 3dmark11. With stock configurations on the graphics card (725/800) I was getting noticeably lower graphics scores, but higher physics scores. When I overclocked to 800/950, my graphics scores were higher, but physics scores were reliably lower.

Im not super smart on this stuff, but it made me curious. Is this perhaps because the graphics card is hogging so much power when its overclocked that the CPU is not getting what it needs in terms of voltage? Is that even possible?

Thanks!

when you overclock GPU, temperature increases, and so CPU goes into turbo less often.

 

That is usually OK though, as most games are not CPU intensive as they are GPU intensive. I think that games will be bottlenecked by the Overclocked GPU way before they would with a sandy bridge chip.

 

in fact, disabling turbo is a good practice when gaming, it decreases the temperature from 80/90s to 70s. under sustained gaming sessions, the decreased temp would increase the longetivity of your laptop considerably.

 

I have a silly question when using Afterburner. If I close down the window after ive set my OC´s and then restart the softwware, they will be back to default. Does AB have to run all the time I want it overclocked?

 

Yes Afterburner needs to stay open, but Sapphire Trixx does not.

 

how was your furmark doing?
whats your max temp mate? (clocked at 850/1000 for 10mins)

 

So how would one go about disabling turbo boost?

 

Change Coolsense to "coolest" mode.

 

Hi all,
I have a problem with HD 6770M 2Gb that dwalk presented some threads ago:

My present configuration is:
- BIOS last version and "fixed" mode according last HP guidelines to enable Intel-Radeon switch
- last HP drivers (8.830.6.2000)


As dwalk wrote, the video card drivers sometimes stop working for 10 seconds (black screen) when I try to alt-tab from game (expecially League of Legends).

I wrote you guru because someone tried to solve this problem with this answer:

From:
RiotEski fanboy thread - Page 11 - League of Legends Community

"Problem:

The only problem is that I'm having some major video driver issues with my laptop's Videocards/drivers and xsplit. When I stream - every 5-10 minutes my screen will go black for 8ish seconds and bottom right a popup will say "Display drivers stopped responding and have recovered" or something like that. It happens often enough and for long enough that it almost guarantees a loss for my team - as almost every crash ends up with me dying.

I have switchable graphics - an intel integrated card and a radeon HD 6770M (I use the radeon when playing / streaming) and windows 7. I've updated all my drivers for both cards and windows updates and the problem persists. I think I'm probably going to end up having to get a new graphics card to fix this (for some reason I always have problems with radeon cards, shoulda stuck to Nvidia). I don't know if the problem is simply that the radeon card sucks or that my switchable graphics are giving me trouble or what, but until I can get it fixed it's unlikely I'll be able to stream again .


Answer:

This is caused by the radeon chip's automatic underclocking of itself. The problem you are having eski is that LOL isnt strong enough to make ur chip clock up to normal speed. I would reccommend downloading MSI afterburner/ati overdrive and clocking ur chip to normal. I used to get this error all the time until i figured this out! it crashed on videos too. GL"


I sincerely do not understand this answer... Do you have an idea how to solve this black-screen-problem using MSI Afterburner or other tips?

Many thanks,
Asa

 

that doesnt make any sense to me either because even if you overclock a gpu using MSI afterburner, the graphics card will still underclock if its not needed

my issue was caused by my overclock, so if this is happening for you and you haven't overclocked, i would first try a reinstallation of your drivers

if you like, you can use the AMD 11.8 drivers. they aren't officially supported by HP so use it at your own risk but I use them and they work fine for me and everyone else who's tried them. (found here http://www2.ati.com/drivers/mobile/11-8_mobility_vista_win7_32-64_ccc.exe)

Run the AMD uninstall program and make sure all your graphics drivers are removed in your device manager. It wouldn't hurt to run DriverSweeper and remove all AMD stuff as well if you'd like but it's not completely necessary. Then run the AMD setup for the HP drivers (its AMD 11.4 version). After its installed, run the setup for the 11.8 drivers. Choose custom install and only install "AMD Display Adapter." Don't bother with anything else. This will keep the CCC that came with the laptop and only install the display adapter for 11.8.

 

Dwalk,

When you run the AMD uninstall program like you said, doesnt it uninstall the CCC?

And what is this "Amd setup for the HP Drivers (its AMD 11.4 version)" that you talked about?

 

I installed 11.4 driver (11-4_mobility_vista_win7_32-64_ccc.exe) but it cannot find my radeon video card. I tried more and more, using DriverSweeper and so on, no luck. At the end I reinstalled my previous HP drivers (I noticed that the version of HP drivers is the same of 11.8 btw), waiting for them to solve the black-screen problem...

Thank you anyway for your support, I will keep following this discussion.
Asa

 

Sorry for the confusion, I meant install the stock HP drivers which happen to be the CCC version 11.4, then install 11.8 over it that I linked in my last post. Choose custom installation and just install the display adapter.

 

Okay I'm lost on how everyone is getting a newer driver for the display adapter. I'm following the directions on getting a complete re-install of the hp display drivers. I then download the 11.8 drivers and choose custom install and when I go to display adapter it says that it is already up to date yet it is only saying 8.830.6.2000. How in the world are you guys getting drivers 8.84 and above?

 

wittynorseman-

You responded a couple posts back about disabling turbo boost by setting coolsense to coolest. Will that setting also throttle back the GPU or just the CPU?

Thanks

 

AFAIK that only applies to the CPU.

 

I'm just trying to find the maximum GPU and CPU operating temperatures. Any info on a good baseline would be great! thanks

 

TJUNCTION on mobile "Sandy Bridge" i5 & i7 processors is 100°C, that is the point at which chip will shut itself down to avoid damage. I am unaware of the max temp for the 6770M; AMD does not have it listed on their web site nor have I found it listed anywhere else.

 

So the next question is:

Who wants to find the thermal limit of their 6770M?

 

Somebody should take one for the team and find out, it sure would be a nice piece of info to have. I know from my personal experience iv never let my temps hit any higher than 90C, i actually try to keep it between 75-80 just to be on the safe side.

 

I nominate you.

 

you are a big jerkface, hockeymass

 

so I swapped out my HDD for SSD (Crucial M4) and did a minimal system restore. Updated all the drivers and everything works great....just one problem, I can't change the voltage in Sapphire Trixx, though I could before the HDD swap. I can still change the memory and core clocks and have no issues there...just the voltage. Anyone got an idea what could be causing this? Maybe the latest amd drivers which I installed (11.10 preview 3)? Can anyone confirm that they were/weren't able to change the voltage with said drivers?

 

and you are being an idiot

 

So I just finished OC'ing my 6770M, got it to 880/1000 stable. Now to see what my 3DMark06 score goes to. (Was 10051) Now if only I could get OpenGL to work...

Edit: Score went to ~11650, 1600 point increase is not bad in my book.

 

^ dump 3DMark06 and use 3DMarkVantage.. i could gain 1k-2k with just enabling TurboBoost in 06.

 

Yeah, I know. I ran 3DMark11 and its about 1700.
