Overclocking the Radeon 6770m in the dv6t 61xx

AluminumFalcon's fps seems low. I got 20+ fps at 768p very high, and on high I got around 35 average fps.

 

Use the Crysis GPU bench.

Crysis GPU Benchmark

 

Thanks for the info. I will run both the CPU & GPU tests thoroughly later today. I did let both loop 3 times each while OC'd @ 850/1000 running 1920x1080, no AA, all settings medium, the CPU bench ran @ 44FPS average, while the GPU bench ran @ 47FPS average. Not too shabby.

 

Gonna run crysis benches tonight when I get home. Also, I am making icons that automatically switch the GPU when you double click them. And the switch to AMD starts MSI afterburner automatically

 

What settings do you all have Coolsense on while playing? I was doing performance mode, but my CPU got up to 94 C while doing that, so I moved it to Coolest mode and got down below 85 C. Performance took a hit, though.

 

I'm on performance mode...Temps are staying below 82.
I ran the benchmark found on the demo, I was getting an average of 28 fps, 23/24 min, 32 max. No AA, settings all high, 768p, OC 850/1000 using sapphire trixx (MSI afterburner doesn't handle that overclock as well). I'm on the 11.5b hotfix.

Is there any reason others are getting better results?

 

Hmm, that's making me a little uncomfortable with my machine. Even with no OC, I can't do any gaming without it reaching 90 C, even after only 10-15 minutes. Do you guys think I should just return this one to HP?

 

How long are you running it for until it hits that temp?

 

Well, yesterday I booted up Battlefield 2: Bad Company, played single player for about 20-30 minutes, then checked temps and was a little surprised to see the CPU all the way up at 94 C. The only way I can keep temps down is by setting Coolsense to 'Coolest' or setting the maximum processor state to 85% or below. Otherwise, my CPU runs at least 10-15 degrees warmer than the GPU.

 

Anyone open up their shiny new laptop and actually replaced the stock thermal paste with arctic silver? (would this void any future warranty claims?)

results?

 

Don't break or mar anything and they won't know.

Just a thought: Maybe if Coolsense was uninstalled, we would regain manual control over the fan in MSI Afterburner and other tools? Cause right now it just shows 30% fan speed no matter how fast it is going... Maybe Coolsense is interfering with fan control?

 

Possibly... that is something to look in to.

 

Did some Crysis SP Demo Benchmarking. I ran it in 32 Bit Mode, Windowed, with DirectX 10. The average FPS boost was 19.4%

@1024x768 All High, 4x AA

Code:

Pass0:35.96 FPS
Pass1:39.14 FPS
@Stock 6770m Clocks

Code:

Pass0:43.3 FPS
Pass1:46.89 FPS
@850 Core/1000 Memory

The Overclock yielded a 20% boost on the first pass and a 19.8% boost on the 2nd pass.

@1920x1080 All High, 4x AA

Code:

Pass0:17.69 FPS
Pass1:18.14 FPS
@Stock 6770m Clocks

Code:

Pass0:20.98 FPS
Pass1:21.65 FPS
@850 Core/1000 Memory

The Overclock yielded a 18.5% boost on the first pass and a 19.3% boost on the 2nd pass.

And as an LOL I ran it with the Intel IGP and got about 3.7 FPS @ 1080P.

 

Nice nice, and Lol @ the 3.7 FPS.

 

I ran it for about 40 seconds and I was like I am not waiting for this to finish but that was about the average. I am sure it would have picked up a bit on the 2nd run but I didn't want to wait for it to do 2000 frames.

 

I do not have coolsense installed and i still have no control over the fan speed :/

 

Go download/install it then....

And no one has control of their fan yet as far as I know.

 

Coolsense does a good job. I just toss it on coolest mode for a few minutes after I play and it gets cooled down pretty easily.

 

I was just referring to what to beaver said is all.

 

I was just running Just Cause 2 on all high at 768p with 850/1000 OC @ 1.055 V. Average FPS are good at about 27-30, lowest dip is around 25. I had been gaming for a good bit when suddenly my computer froze and blue screened on me. I guess it got too hot....

Will this cause any permanent damage? Does this mean 850/1000 is unstable for me? Why have I been able to run it in the past? Why can others run it?

 

Because not all 6770Ms are made equal. Some chips will have a higher tolerance to OC than others. For you it looks like you may have to scale down a little and check your temps. Start with your clock speed.

Sometimes a burnout from an OC can happen if youre unlucky. I managed to burn out my desktop HD6950 (and this is the Asus DIRECT CU II version of the 6950 which has one of the best if not THE best coolers attached to it) a couple weeks back which was infuriating. But at least with that card I can easily replace. You cant replace a 6770M so I'd be extra careful. Think, do you really, really need that OC that high or on all the time. Last thing you want is to have only the HD3000 to work with.

I personally wouldnt overclock a mobile GPU that I cant replace.

 

I find putting coolsense on coolest mode while overclocking the 6770m gives the best result. It shaves 7-8c off the cpu temp while giving a ~15% net gain in performance in most games (@850/950). Performs much better than leaving turboboost on and the gpu on stock clock.

 

Hmmm what if I'm covered under warranty, could HP replace the card then? And yeah it's not that important I OC...should I lessen clock or mem speed?

I thought coolest mode on cool sense hurts performance?

 

I believe coolest mode disables turboboosts and it does hurt performance, but combined with overclocking the GPU you will still see a net gain in fps (quite a significant gain too) in games because they utilize your gpu more than the cpu. You should also see a drop in temp (at least for me it does, by 7-8c).

Someone suggested to manually disable turboboost by setting processor speed to 99% in power plan settings. It does the trick but it wont affect idle temp where as coolest mode can lower idle temp by almost 10c

 

I prefer the 99% method so the fans stay quiet on idle.

 

Will HP replace for you? Depends if they find out you OC'd or not. You OC your GPU at your own risk and it's not really HP's problem. If your 6770M burnt out at normal clock speeds then yep it would be their problem.

Try incrementally dropping both mem and clock 10 - 20 Mhz at a time.

BTW just because people on this thread have achieved "stable" OCs at certain speeds does not mean you can. And you certainly shouldnt go straight to a speed that another person has stated as stable. ALWAY OC your GPUs incrementally, and stress test at every change. It's very easy to tell if something is not going to be stable early on with Furmark.

 

They probably wouldn't know if you OC'd or not, if you just restore your computer.

 

So 20% is the highest we can go? I wanted 460m status.

I can live with it though lol. Stock 6770m was more than sufficient.

 

IMO qfn is totally off the mark. Coolsense wrecks the performance in games. So much so that any overclock would not make you better off.

 

Those having lockups and heat issues can move their core clock down, and it will likely resolve the issue with minimal performance impact. There is essentially no performance gain from 825 to 850, and even the difference at 800 is minimal. The memory OC is making a much bigger difference than the core OC, so dial back your core, and you will likely be able to leave your memory alone. Most of the 2GB cards should be able to hit 950-1000 on the memory OC stable.

 

With coolsense on coolest mode and gpu @ 850/950 I get 68fps in just cause 2 'desert' benchmark. With performance mode and stock clock I am getting 60fps. I am also playing Crysis 2 @ 1366*768 extreme setting with no noticeable lag. Coolsense does have an impact but it definitely wont "wreck" your performance.

 

Actually, he's not wrong depending on the game. In CPU-limited games, coolsense will decrease performance but in GPU-limited games, the overclock helps immensely. I find it helps especially for games played in 1080p. Even in Starcraft 2, I prefer 99% + overclock when playing in 1080p.

 

I made something I thought you manual fans would like. I made desktop shortcuts/icons that toggle the cards. You need to set your hotkeys for switching to the ones these shortcuts use. They pretty much fire a hotkey when you press them.

For the AMD Card, set your hotkey to Shift+Control+Alt+A
For the Intel Card, set your hotkey to Shift+Control+Alt+I


To do this, open CCC from the start menu. Then in the top right corner, hit preferences. Then Hotkeys. Now in the top dropdown box, select Mobile Intel HD Graphics. Just make the hotkeys that I posted. They are too large to be attached, so I have them on MU. Click Here.

If you guys have other hotkeys already set up that you prefer, post them here and I can recompile the program with those. I also have 2 icon files in the zip incase the icon is wrong or you want to make a shortcut.

Enjoy!

 

If it's a benchmark you're using to test - I.e. something you do not control and is built into the game to test - it rarely uses a lot of CPU power.

When you're in an actual game it does a lot more CPU.

I was playing Crysis 2. It went from almost unplayable with coolsense on and an overclock, to fine with no coolsense and no voerclock.

 

Does it make. Difference if you incrementally go to a certain speed vs put it in initially? What do you guys think of boosting voltage to 1.055 on sapphire trixx?

 

Dont think it'd make any difference

increasing the voltage will increase stability, provided that it isnt overheating. Some people do it and some dont because it will shorten your GPU's life. My dv6 is only 10 days old so i prefer not to up the voltage....but you know when you first bought a new toy u take extra care of it and after awhile you just dont give a crap anymore. Im sure after a few months ill start messing around with voltage/higher clock

 

Haha that's fair enough...I found this thread that's pretty interesting, it's a bunch of people posting their stable 6770M overclocks. Looks like people vary pretty radically in their overclocks. Interesting nevertheless.

First post of the thread

 

How do you set it to 99%?

 

I can comfirm what was being said earlier about playing with Coolsense on 'Coolest'. I have been doing that with Battlefield: Bad Company 2 and Crysis 2, and the performance drop is very minimal, if not nothing at all. I compared 'Performance' and 'Coolest' side by side, and noticed maybe a few frames less on 'Coolest'. It definitely helps keeps temps down, though, sometimes even keeping them down 10C-15C.

On a different note: I really want to repaste my CPU and GPU, but I don't know how to do this for the life of me. Are there are companies or stores out there who can do this?

 

Nvm I got it. How hot is too hot under Furmark? I have coolest AND 99% under 850/1000 and I'm hitting 90 max.

 

850/1000 is only yielding me a 1724 on 3dmark11...shouldn't I be in the 1800s?

Running 11.5b hotfix as far as I know...

 

On my Envy the more recent the driver, the better the 3dmark score

 

I thought the 11.5b hotfix was better than the 11.7 out right now? Others in this thread said they were using 11.5b and got into the 1800s with 850/1000 or a little less.

 

Maybe it's because you're on an i5? I'm not sure.

 

I actually had to revert to the stock HP drivers because Minecraft seems to crash on anything but those drivers. >.<

 

How do you check what driver you have running?

So I ran some furmark tests. I did 800/1000 for 30ish minutes on performance mode, and temps peaked at 88, usually hovering at 87. I dunno if those are good numbers, but they're a bit hot for my taste. Anyway, I turned coolest mode on and ran 825/1000, and furmark stayed at 83 max, hovering around the low 80s. In my opinion, 83 sounds a lot better than 88--so long as it stays below 85 I feel pretty satisfied.

EDIT: This makes me wonder how well the fan runs in performance mode...and if there is a way to keep turboboost while blowing the fan full throttle. Could that be achieved by uninstalling coolsense? I dunno. Would I want to constantly uninstall and reinstall coolsense? Nope...

 

I don't know how relevant this is, but I ran 3dmark11 with the different coolsense settings and received the same exact score each time. I'm not convinced that it worsens performance that much, if at all, to run it on 'Coolest'.
