Overclocking the Radeon 6770m in the dv6t 61xx

Do you have it checked so it automatically selects the power saving gpu when on battery?

 

Is anyone else having the same problem as me? PC crashing when running game OC'ed

 

Thats a common problem... It means your OC isn't stable, and you need to lower it.

 

Computer instability when OCed usually means you've OCed too much. Try reducing the core clock speeds or using the values on the first post in this thread, which are 850 core / 1000 memory.

 

How much of a boost in game are we looking at with 850/1000 over stock? 20%?

 

Though there has been a little variance for each person, I'd say about a 20% increase and easily more. The OCs bring the 6770M much closer to the 460M, and nearly surpassing it.

 

That is my problem. I have tried all the clocks on the OP and I just tried 850/1000 again and my pc still freezes.

 

Are you sure it is caused by the graphics card? Does the instability continue even with the clocks returned to their stock levels? If not, then make sure you are using either the 11.5b (recommended) or 11.7 drivers. With those drivers, if it continues, just keep trying to lower the clocks until you find something that works.

Also, try running one of the many programs that tell your the GPU/CPU temperatures and find out if its getting too hot.

 

You should not be overclocking if you are just randomly trying other people's numbers. You should increment slowly until you exhibit the pc freezing and tone the MHz down from that point by some MHz.

 

Not all GPU's are created equal! I cannot reach 850/1000 on mine and be stable either. Everyone's has slightly different characteristics and limits as to how far you can overclock it.

 

Ah, thanks for the help guys! It was like y'all said. It was set to 'Maximize Battery Life' when on battery, so that was what was causing the GPU to poop out.

One more question: what temps would you say are OK for gaming? I got up to 88 on my CPU and 81 on my GPU with 825/980, and I was a bit worried about the CPU. I went in and set it to maximize the CPU at 85%, which brought my performance down noticeably. It did, however, stay below 80 that way. Any opinions?

 

I run my oc at 850/975 and my gpu hits about 80C while playing rift at 1080p on high settings @ ~25 fps. 850 on the core seems to be the sweet spot but the memory is a little more flexible. I went up to 1025 on the memory but at this point i only noticed a 1-2 fps difference and the temps were really high, about 85C, which is probably as high as i would run it. So i think im going to stick to either 975 on the memory or 1000 at the most.

 

Wow, pretty nice at 1080p.

 

How about CPU temps?

 

wow, I'm SO glad I stumbled on this forum during a google search, epic info here!

I have a dv7-6143cl, and currently have my 6770m (1gb) overclocked to 815/950 stable. Seems like anything over that and I get random freezes. It appears I don't have as good a chip as some of the rest of you, but it plays all my games just fine.

Unfortunately, I have one of the models with the brushed aluminum top fascia, meaning the area directly to the left of the keyboard gets 'scorching hot.' And yes, I do mean scorching...and yes, even at stock speeds. I've checked my temps and everything seems within reason, with nothing ever going over 85 degrees. My question is, what kind of changes do you guys think I could expect from taking the time to open this sucker up and replace the stock thermal compound with arctic silver? Is it even worth the trouble, or are the results pretty negligible? Perhaps even a slight bit more overclock out the Radeon too?

Thanks again!

 

The brushed aluminum/stainless case shouldn't be causing the issue. It's likely a poor connection between your heatsink pad/paste connection to your GPU or CPU. It could also just be the heatsink coming into contact with the case. I have a custom build with the same silver case, and mine doesn't even get warm at the left wrist, even with OC set to 825/975.

 

Not really. All dv6t/dv7t laptops get hot. My Envy 17 gets hot.

It's mostly just a matter of if you can deal with it, then deal with it. It's tolerable unless you have fragile skin or something.

It should not be so hot that you get burned. It should feel warm yes, but not at the level where you get burned.

 

Thanks for the input. That's odd. Because my temperatures aren't anywhere out of the ordinary, but when I'm gaming the upper left corner of the aluminum face gets extremely hot. I'm tempted to open it up, just hate going through the chore of connecting/disconnecting small ribbons/wires...especially if it'll only make a 2 or 3 degree difference.

edit: jaguare, that makes more sense. I can definitely deal with it, as my hand would never really have a reason to 'wander' up towards the upper left corner of the laptop, but it's definitely a lot hotter there than any previous laptop I've owned (most of which were VAIOS, but only core2duos)

 

My cpu temps were roughly the same

 

I just got my dv6190us a few days ago and just started OCing. I guess the Crysis demo is as a good a benchmark as anything else for me...I'm doing 800/1000 at the moment, anything above 1000 crashes for me (haven't tried 850 alone yet). On Crysis high settings, things run well ~25 fps, dips to ~20 fps with 8xAA. Or I can do all very high for ~20 fps. All of these are on 768p. Although these are all guestimates, how can I directly measure fps?

EDIT: gpu temp stays below 80 around 77.

 

Download and install a program called Fraps...

FRAPS show fps, record video game movies, screen capture software

 

By the way, AA does very little in Crysis. The thing that needs antialiasing the most - foliage - is not affected by AA. It's usually best to just turn off AA and avoid the performance hit.

 

I kicked it up to 850/1000.

I did not run 3DMark Vantage this time because I believe why bother when I am running 3DMark11. I threw in 3DMark06 because there are a lot of DX9 games, they continue to make most games in DX9 and just for the hell of it.

3DMark06

edit: whoops, norse was kind enough to drop in on the dv6z thread and show us how he was coming and I ended up inadvertently posting my reply in the wrong thread after following his link

Scores are nice. But in-game performance actually shows the performance boost that actually matters.

 

Does the CPU automatically turbo when necessary?

 

At least these benchmark apps are free and they do show comparative results from overclocking. Have any suggestions for benching or are there only complaints?

 

How come you are so easily annoyed? Take a breather there before you keel over from your high blood pressure.

I'm not sure how you take it as a complaint. I'm saying that regardless of the scores, what matters is the end is the performance boost in-game (GPU intensive) with stock fps vs OC fps. If I offended you with that statement, then I apologize.

 

which is exactly why things like 3dmark11 exist because games themselves generally make poor benchmarks

a 20% increase on a 3dmark11 score is ~20% increase in a game as well

 

Dwalk, Im in a rush so I can't explain, but if you really think that 20% in 3dmark is 20% in a game you are sorely mistaken.

 

i put the ~ in there for roughly

obviously its not the truth in every possible scenario but in a very general sense, yes its a rough indicator

 

If you just go by scores, then apparently the 6770m has been OC'd to 460m territory already.

And we all know that is false.

 

but my overclocked dv7 runs starcraft 2 just as well as my friends sager with a gtx 460m

so... ? ? ?

no, obviously given the giant list of things that could be different from user to user, 3dmark11 is not good comparison tool for details but for general comparisons it does its job fine

 

If you guy want to see roughly how different clocks compare in-game you should use in-game benchmarks, like the Crysis GPU and CPU benches, Just Cause 2 bench, etc. But those aren't necessarily free.

 

I rather not argue, but I rather just debate this civilized as long we don't go for each other's throats .

The 460m is roughly 40% more powerful than the 6770m in games. An overclock to 1850ish (above 460m's 1800 score) only results in a ~20% boost for 6770. So whatever comparison you are drawing between those two laptops are off unless you have overclocked even more or his 460m sucks.

Plus Starcraft 2 is a CPU intensive game, and not a good game to GPU benchmark...you need a game like Crysis like was mentioned.

 

+ starcraft 2 seems to run better on radeon AMDs for whatever reason

comparing to the 460m is pointless anyway because we're talking about a performance boost with the 6770m

1500 score before overclock compared to a 1800 score after overclocks indicates a 20% performance boost and actually results in about 40-50 higher framerate in starcraft 2 on low settings (like 205 instead of 160)

 

Like I have posted before, the 6770m smokes the 555m in benchmarks but the 555m is on average just as good if not better in games

 

idk why you guys keep bringing up other cards

the 6770m score of 1500 stock clock vs 1800 overclock = 20% increase which can be roughly seen in games

the score of those nvidia cards are irrelevant

 

Look I made this thread as a tutorial to help people and for people to share their overclock suggestions and results. Not to bash the legitimacy of benchmarks and start e-peen wars over graphics cards.

 

If by saying that you mean an increase in 3dmark 11 equals an increase in game performance - yes you're right.

But it's not a 20%-20% correlation. It tends to be less.

But I'm also saying 3dmark 11 is a contrived benchmark so looking at its scores to determine gaming performance is not a good idea.

 

No offense was taken on my part. There weren't any lines to read between, as there was only one line, at best only subtle sarcasm was there.

Are there any freely available game demos to benchmark? I only have Dirt 3 available at the moment, everything else is in storage and I'm 2200 miles from my storage unit.

I will upgrade to the 11.5b hotfix and rerun 3DMark11. Dirt 3 has it's own benchmark, but it is inconsistent.

I'm only comparing the results of the the stock clocks with overclocked for now, be that with whatever I have available to me.

 

Crysis 1 demo
Alien vs Predator demo

Total War Shogun 2 demo

 

Going back on-topic. Getting nowhere and like con said, we are off-topic.

Crysis 1/2 demo is also available if you want to take that out for a spin.

EDIT: Ninja'd.

 

you're right about 3dmark11 but it sounds like you agree with me so im not sure whats going on here

 

I don't have a link to a stock 3DMark11 test on 11.4 drivers, but I do think I saw a result of P1575 someplace. I would say that a list could be compiled of overclocking results with various clocks, drivers & benchmarks. One thing I do notice is that the physics results and the CPU clock tend to be all over the place even running the exact same test multiple times, damn you SpeedStep.

3DMark - driver 11.4 - 850/1000
AMD Radeon HD 6770M video card benchmark result - Intel Core i7-2720QM Processor,Hewlett-Packard 3388 score: P1825 3DMarks

3DMark11 - driver 11.5b - stock clock
AMD Radeon HD 6770M video card benchmark result - Intel Core i7-2720QM Processor,Hewlett-Packard 3388 score: P1614 3DMarks

3DMark11 - driver 11.5b - 850/1000
AMD Radeon HD 6770M video card benchmark result - Intel Core i7-2720QM Processor,Hewlett-Packard 3388 score: P1878 3DMarks

I'll install the Crysis 1 demo, then run and log the results.

Crysis 2 demo is a "no go."

 

Fail on my part. Guess only numero uno.

 

I'm experiencing weird random freezes now, which is quite frustrating. I've gone from 820/950 (gaming Team Fortress 2 for HOURS, not an issue) then all the sudden my desktop will freeze up out of the blue.

Bumped it down to 800/900 and now it seems fine. But I wonder why my overclocking results are so underwhelming? Or could it perhaps be due to the 11.5b drivers not being best for my system? Has anyone gotten better results/stability using the latest official HP drivers instead?

 

Some cards just don't OC as well as others.

 

I've been messing around with the Crysis demo a bit using sapphire trixx to OC....800/1000 is stable, 850/1000 @ 1.055 V may be stable, I haven't tried it for long enough to be sure. On all high at 768p, OC gives about 25 fps. Bump things up to very high and fps is still playable but at 17-20 fps. No AA, else fps drops...plus I here it doesn't do much on Crysis. Anyone getting any better luck? Remember this is the demo so it may not be fully optimized..

 

I just played with the demo for over an hour running at 850/1000 1920x1080 no AA, & no AF.

All settings to medium ~42-56 FPS
All settings to high ~22-26 FPS

I also ran Furmark for 20 minutes @ 1920x1080 8x AA. I equipped the laptop with my "cooler" and it never went higher than 68°C, it was 21.72°C in the room. For the inept the room was 71.1°F and the GPU was 154.4°F.

Apparently I can't take a screen shot with Furmark in full-screen, so I have no proof for the unbelievers, but if need be I could rerun it windowed to get a shot or take a video with Fraps. Someone will have to ask though.
