Overclocking the Radeon 6770m in the dv6t 61xx

Now you guys got me wondering if i should reinstall coolsense lol. I mean if i can drop my temps by 7-10C with just a minimal loss in performance i think it would be worth it and extend the life of the laptop. Anyone else got any theories on this?, i would like some more info if possible.

 

If you dont want to reinstall coolsense, just set ur cpu to 99%. Its an alternative. If you are happy with the result, then go ahead and reinstall coolsense because it lowers your idle temp as well.

Go and see for urself. Try the two settings: 100% + stockclock vs. 99% + overclock. you'll be surprised.

 

If you use "High Performance" power settings, I think CPU is already set at 100%

 

86 degrees max with 825/900 in sc2. 1080p ultra minus shaders, pretty nice.

 

So something weird just happened. I ran an OC for 20 minutes on furmark, didn't pass 84 degrees. Figured the OC was stable, and tried to rate it on WEI. When it got to "Decoding Media Tuner" or something, the screen froze and I had to restart the computer. I'll re-try it with performance mode on, but I find it odd that WEI would crash while furmark wouldn't.

Also, Kalookakoo, nice! Was that with coolest mode on?

EDIT: Ran it on performance with a lower OC and it blue screened. I'm sitting here scratching my head...I can run furmark and Just Cause 2 fine, but WEI crashes?

 

No performance in coolsense. I had the cpu max to 99%. Furmark throws my temps to 90+ if I go anything 800/850 ish.. maybe its my drivers. ill check again later

 

850/1000 with a 3dmark11 score of 1711 doesn't seem right at all. Can someone tell me what the best drivers are to use? I feel like I'm overlooking something. (pretty sure I'm using 11.5b)

 

What does not seem right about it? It seems pretty close to the machines I am running with the same overclock, but there are a few differences between your laptop and the ones I'm playing with. Although, I do not know how much each of those differences account for. Besides it is only a benchmark.

What is your score without the overclock?

 

860/1030 is the highest stable clock i can get, but i had to raise voltage a notch to reach it.

Tested for 30 minutes using furmark, temps are 78 for CPU and 87 for GPU with coolsense on coolest, and 91 CPU 89 GPU on performance optimized.

I find it weird that some games like nfs:hot pursuit take a huge performance hit on coolest mode while in other games the difference is minimal.

 

What's your voltage?

 

Nobody likes my switching icons?

 

I personally think the icons would be legit. Tryign to go back to a DV6t, and when I do i'll def be using them. Thanks lol i went from dv6t to z and im tryin gnow to go back to t....except prices have gone up

 

whats your highest 3dmark vantage score guys?
has anyone reach 10k before?

 

1.055

beware though, raising voltage reduces lifetime expectancy.

 

When you receive it, say you'll return it and get some credit. lol...

 

1470 Stock.

99% max cpu and performance in coolsense. Eh nvm then, 17% increase in scores. I just saw some 1800s in this thread and wondered what was going on...

 

does putting the cpu max performance to 99% prevent it from turbo boosting? if so, whats the point in putting coolsense in performance mode?

what am i missing here? xD

 

Yeah putting it to 99% stops it from turbo boosting. I believe putting coolsense to coolest throttle the cpu down to 60=70% I believe. Read it somewhere awhile ago, memory could be blurred.

 

I wish there were a way to boost fan speed while enabling turboboost...

 

My FurMark benches:
1366x768, Burn-In, No MSAA, 10 mins.

Stock Clocks:
Avg. FPS: 16
Max Temp: 80
Avg. Temp: 79
CoolSense Setting: Performance

Overclock (800/950):
Avg. FPS: 18
Max Temp: 85.5
Avg. Temp: 85
CoolSense Setting: Performance

Might try a higher memory clock. That bench ran pretty smooth.

 

anyone? hmm

 

??? Are you kidding me???

When I push my GTX560M OC to near it's absolute limits I can get just over 11k on Vantage. That's a GTX560M. There is no way a 6770M will be able to break the 10K mark. I think I have managed to get the 6770M to about 8500 on vantage though.

 

I tried 800/900, and Cinebench Open GL 64bit went from 47.96 to 48,40 fps.

Half a frame increase, seriously?

 

Wow really...
I thought ati 6770m would be faster than ati 5850m according notebook graphic review rank..
I was using alienware m15x and msi gx640 with ati5850m before. Breaks 9k vantage easily and once I reached 10k on my m15x last time lol
Never thought higher gpu rank + i7 sandy bridge processor couldn't break any near 9k..

 

What temps are you getting stock vs OC?

Also, just for kicked I OC'd my 6750m to 6770m clocks (sort of, 725/875, I don't think 6750m memory gets anywhere near the 1600) and hit 1600+ regularly (6680 in vantage). Probably the CPU though.

11.8 drivers if you're curious.

 

Yeah, in fact I may have it wrong. My vantage score couldve been low 8K but I dont retain these scores so I forget. I think my clock was 850/1000 with 11.7b (or 11.6b, whichever you want call it). The 6770M is good...but it's not that good. It's a mid range card really.

 

For those of you thinking whether to disable turboboost, heres a very comprehensive review on the i7 in regards to cpu's impact on gaming performance:

Intel Sandy Bridge Processors Gaming Performance: Part II - Notebookcheck.net Reviews

bottom-line: adjust accordingly for each game.

 

Look here: almost 11k with a 6750m.

MacRumors Forums - View Single Post - 6750m EXTREME OVERCLOCKING guide

 

I updated my drivers and now, im unstable with my overclocks that were stable before? What's the best way to revert back to 11.5b?

 

um...
this is 3dmark 06... he's talking about 3dmark vantage...

 

omg, i was playing Street Fighter 4 arcade addition on stock and my temps reached 95degrees

 

Why not tell us something pertinent to the subject of the thread?

 

have you guys tried to upgrade your volt to 1.10v-1.15v?
that would help you to get a higher overclock though..
maybe lets try to reach 900/1100

 

Try it on your own laptop first.

 

Still on the way to singapore lol..
Noone tried to flash the voltage before using rbe? Hmm
What software do you guys using for overclocking gpu?
Saphire trixx? I think we could manually overvolt the voltage by using that software yea..

 

My highest O/C scores were p8286 in vantage with 875/1000 and p1905 in 3d mark11. The odd thing is that once I go higher than that I seem to get lower numbers. Is that because I'm not adjusting the voltage?

That said, 850/1000 is seems to be stable for me in games, and it is a nice boost as well despite my horrible temps. I'm beginning to think that my CPU hates LIFE.

For the most part I'm using vantage to monitor temps. With no overclock I'm hitting 89c (with a cooler), with overclock it's around 92c. Without the cooler my CPU hits about 94c :/ . My gpu never gets higher than 90 on the furmark burn in test, but while gaming and benchmarks my gpu has never gone above 79c, even while overclocked.

Sorry if that this has been stated before, but with furmark, what settings should I be testing? Burn in? Extreme burn in? Windowed mode? Non Windowed? I've done some research but there seems to be no actual consensus.

 

Im a little skeptical when it comes to playing with voltage myself lol, plus it really has a negative effect on the gpu and will shorten it's lifespan. I think it woul be more wise to get what you can out of the stock voltage. I am currently running my oc at 875/1000 and it is stable so im good with that. Also i have coolsense set to coolest mode so my temps never it any higher then 80 with my overclock and the performance loss is minimal when compared to setting coolsense to performance mode. Overall i am quite pleased with how far i am able to stretch the 6770

Now if only someone can hack the WLAN whitelist so i can get rid of the crappy wifi link 1000 card and replace it with something better ill be a happy camper

 

According to notebookcheck.net and 3dmark vantage, the 6770m can overclock slightly beyond the STOCK 460m speeds, that said once the 460m is overclocked it breaks 10,000K and more.

 

I did the 99% CPU thing to keep turbo boost from happening and my cpu temp is down by at least 10c. The thing is that with most games it's not really an issue, but with MMO's and cpu intensive games it is a performance hit. Not a huge hit, but a moderate hit none the less. I may have to re-paste in the future :/

 

Yeah. I play SC2 with ALOT going on without turbo boost and I'm never the one to start slowing down the game.

 

Here is my latest run.

AMD Radeon HD 6770M video card benchmark result - Intel Core i7-2720QM Processor,Hewlett-Packard 3388 score: P1969 3DMarks

I also ran Furmark for 10 minutes with my blower on the laptop. At around 5 minutes the temperature peaked at 87°C (ambient temperature was 22.3°C). It remained at ~85-87°C for the rest of the run. I believe under normal conditions without my blower there is not way that this overclock would be safe.

The OC was 900/1100, +0.01V using Sapphire TriXX, cooler was a Lasko 3-speed blower.

 

The 99% cpu tweak has been working really well for me temp wise, Rift on the otherhand, at 1080p "low" settings at least yealds me 35+fps. I can go ULTRA with 1366 and get almost the same results, if not more (FPS) it just looks bad on my external monitor.

..............your speedtests my mother!!!....I'm in Philadelphia and stuck with comcast lol

 

What "blower" are you using? My CPU get's HOT at stock. OC at is a deferrence of about 2-3c max. GPU never really hits higher than 80c...The cpu hits 94c at times...O/C at work rinning 3dmark vantage

 

does putting the cpu to 99% allow the fan to cool the cpu more or something? doesn't coolest mode do the same thing?

 

putting cpu to 99% disables turboboost. Coolest mode disables turboboost and allow the fan to spin more often.

 

I though coolest throttles the cpu below 80% or something?

 

That i am not sure, but I would assume so coz my temps while gaming on 99% seems to be higher than running on coolest mode

 

I do not think I am going to get the GPU any higher than this. Benchmarks software is locking up when I push for 950MHz. Any higher would be stupid in the dv6t. I am tempted to open both of them up and apply some quality thermal paste to help keep the temps down.

925/1200 - 1.065V

3DMark11
AMD Radeon HD 6770M video card benchmark result - Intel Core i7-2720QM Processor,Hewlett-Packard 3388 score: P2017 3DMarks

3DMark Vantage
AMD Radeon HD 6770M video card benchmark result - Intel Core i7-2720QM Processor,Hewlett-Packard 3388 score: P8943 3DMarks

I might be able to get the Vantage score over 9000!

 

Is it proven the 2gb cards are more readily overclocked? Seems the 2gb people are getting the best numbers. I went 850/1000 fine before, but now it's unstable because I accidentally updated my drivers, and now I can't get it back to performing the way it had been.

 

I do not think the 2GB 6770M would have an advantage over the 1GB part. Both of the dv6tqe I am tweaking are equipped with the 2GB 6770M though.
