6750m extreme overclocking guide
- Thread starter Necriss
- Start date
- Sort by reaction score
Bootcamp is the best way to play games, as it loads Windows in a native environment.
I get freezes with my OCed 6750m (11.11) driver and the latest BF3-patch on my 2011 i7 MBP.
Since I run default settings without OC, the freezes are gone.
1280x720 works best for me (40-80fps) on my 1920 x 1200 screen

Can you link me to the direct link please? I tried looking but everywhere I go it downloads the auto detect software
Thank you
My situation
Hi, i'm new in this forum. Sorry for my English, i'm Italian.
I've overclocked my Macbook Pro 2011's 6750M to 780/980 at 1V (by default) with Afterburner. my CPU is 2.2ghz and my ram is 8gb 1600mhz.
In last 3 days i've finished Battlefield 3 without crash and all runs smooth.
My GPU temps (measured with GPU-Z) are 87C° avg and max is 90C° degrees.
I ask you: this situation is normal? My temps are corrects and safe?
I've void my warranty with this OC?

You may want to try 780/980 @0.955V to see if this helps with the temperature. Your avg temp could be a tad lower but its not extremely bad. You may also try redoing the thermal paste

Try it with .955v with 775/975
Thanks for replies. With MSI Afterburner the voltage slide is lock.
Maybe i have to try with ATT??
Yeah the tool trays is what I use, and GPU-Z to make sure the voltage and speeds are correct.
I also reapplied my paste, and definitely notice a lower temp while playing BF3. Went from 90-92 peak to 80ish peak. I used MX-4
I just got my 2.3 Ghz Early 2011 MacBook Pro and I decided to play around with Bootcamp and overclocking my GPU to play Skyrim. I put together some results here for you to look at. Temperatures were 83 +/- 1 degree for any setting I threw at it, including stock.
Test Setup:
2011 MacBook Pro 2.3Ghz with 1680x1050 screen with external 1920x1200 24" HP monitor
Gaming PC Comparison - i7 920 2.66 Ghz 6GB RAM with a Radeon 5870x2
For Skyrim I started a new game and when the character says "Hey", I start a 120 second FRAPS benchmark. No controls are touched.
For Cinebench I just run it
For Lost Coast I just run it
DC = MBP Default Clock (600/793)
OC = MBP Overclocked (750/900)
OC2= MBP Overclocked (800/900) - I was having so much success at 750, I decided to go slighly higher for the "ultra" tests.
GPC= My gaming PC WITHOUT Crossfire
GPX= My gaming PC with Crossfire
Skyrim:
Clock : min, max, average
(This is just a reference for as fast as I could make the default clock go)
1280x800 - Low
DC : 37, 61, 52.958
1280x800 - High
DC : 23, 35, 28.667
OC : 28, 40, 33.300 Gain 4.6 FPS (16%)
1680x1050 - High
DC : 17, 25, 20.567
OC : 20, 30, 24.867 Gain 4.3 FPS (21%)
1920x1200 - High
DC : 14, 21, 17.258
OC : 17, 25, 20.792 Gain 3.5 FPS (20%)
1920x1200 - Ultra
DC : 10, 17, 13.692
OC2: 13, 21, 16.775 Gain 3.0 FPS (22.5%)
1920x1200 - Ultra
DC : didn't bother
OC2: 13, 21, 16.775
GPC: 21, 50, 33.200 Gain 16.5 FPS (98%)
GPX: 19, 48, 32.475 Loss 0.73 FPS (-2%)
Then I decided to run Cinebench to get a somewhat synthetic result:
Cinebench -
DC : 42.5
OC2: 53.2 Gain 10.7 FPS (25%)
GPC: 49.0 Loss 3.2 FPS (-5.6%)
GPX: Doesn't work with Cinebench
Because the Gaming PC was actually slower at Cinebench, I decided to pull out the old Lost Coast demo from Valve. I also wanted to test to see if ATI Tray Tools had any effect on performance. So I ran one test without tray tools running:
Lost Coast - 1920x1200 every setting maxed (Max FPS possible is 300)
DC - 113 FPS
OC1 - 138 FPS (+22%)
OC2 - 145 FPS (+ 5%)
OC2 - 151 FPS (+ 4%) NO TRAY TOOLS
GPC - 222 FPS (+53%)
GPX - 216 FPS (- 3%)
Observations:
* Going from stock clock to 750 / 900 gives a ~20% boost
* Going from stock clock to 800 / 900 gives a ~25% boost
* A 6850 / 5870 Desktop ATi card is 60-100% faster, even on a slower CPU
* Crossfire X seems less than worthless under these conditions
* At this point, I think Skyrim is a game you will need to tweak to get good performance (30 FPS + all the time) until the drivers are better

strange OC problem
hello everyone, i'm trying to do an OC too to my MBP 13's geforce 320m as i used to but since it arrived from the warranty with a new board(wich means new cpu/gpu) that, the OC i used to do without any problems it's not working so well...(i took it to the warranty because of another problem with overvolted USB ports that fried up the board)
when i'm playing any game without OC there is no problems but when i apply the OC, games randomly freeze, than comes a black screen and goes back to the game but with a very poor performance with very low FPS!!
the OC i do is 644core/1359shader on the clocks with EVGA precision and the temperatures stick in 80ºc and when i'm playing with the help of my cooler i get 70ºc so it is not a eat issue
if i rester de OC and the game it doesn't solve the problem.i have to restart the computer for evreything to be ok again
can anybody help me with this?
thanks in advance

I'm new with Macbook Pro & 6750m and trying to update the driver to a more current version (bootcamp automatic install is 11.1), but when i install it i get "no compatible hardware found"... which driver can i install? im on win 7 32bit... thanks for any help
I got the drivers here. http://benchmark3d.com/amd-catalyst-11-12-8-920-0-whql.
Make sure to get the Mobility version.

6950m
Hello guys, Ive been skimming over this thread to see if I can find any information on overclocking an iMac with the 6950M, but I'm yet to find any. So I went ahead and tried some based on you guys' result of OC'ing with the MBPs..
My results have been very pleasing.. seeing low temperatures and fps increase in the games I've tried. Almost too low of temperatures... and that is why I came here
Example: at 800/1000/1050, (800 is the maximum on saphiretrixx, and I'm afraid to touch the volts) and with the GPU at over 90% load, the temperature never passed 71° with the fan on minimum and inaudible. If I would crank the fans, it would drop to a maximum of 51° (Even though the fans were only at about 80%, excluding the HDD fan which was at minimum)
So, I have deduced that this is as a cause of the much better ventilation and heat dissipation that the iMac has over the MBP. Maybe this is not the case... but something is clearly different.
Therefore, I was wondering if there are higher limits for overclocking the iMac over the MBP? And if so.. how do I surpass the 800 maximum in saphiretrixx? The last time I tried to use ATT it did not work.. but I could try to reinstall. Also.. what about the overvolting? I have not read much info on that here (but I did notice that when I down clock the memory, the VDC goes down, yet it would never pass 1050 on its own)
Any thoughts?
(Btw, the specs are that of an base-model iMac 21.5" 2011)

Battlefield 3
Hi guys
Just a quick question. I have my MBP 6770m set at 800/900 995v (ATI) and getting 40fps+ on Low settings (battlefield 3) on windows 7 64bit (bootcamp)
Now i was just wondering ....... (noob question) Can you intel turbo boost & overclock or will it melt the CPU.
Looking at using intel turbo boost to push my 2.2 i7 upto 3.3ghz. (I am aming to push the machine to max when gaming and cool down when not with the intel boost, dont know if this is possible as i already have pushed the core to 800)
Is this possible or am i talking rubbish?
Also has anybody run battlefeild 3 790/1000 955v????

Wow this thread has grown! barely use my macbook anymore. IF you are getting artifacts, freezing, display driver not responding INCREASE your voltage in 0.05 increments until its stable.
You're not missing much performance on 800 (check crysis2 bench on FP). Card is wildly unstable beyond 880 although iMacs have better cooling you may find it will run. afaik ATT is the only software which supports voltage control. MSI afterburner can set clocks beyond 800 if ATT doesn't work for you.
CPU automatically turbo boosts when a game is loaded under performance profile in win7. Lowering the resolution and forcing fullscreen strech with CCC will improve performance at the cost of visuals.

See i read that Windows 7 64 bit didn't push the i7 to turbo boost auto?
If i do drop res to 1440x900 and stretch with CCC it go's fuzzy (like i am not wearing glasses at distant) on Battlefield 3. Even if i select it in game it does the same so i cant help but set it to 1680x1040.
Really trying to push this game past +30fps (people quote 30fps on high)
for the win

I'm on 750/900 .955v
High Textures, medium everything else, AA off, Post-AA high, 8x AF, Low shadows, no motion blur, SSAO on, 1440x900 and im getting 30-55fps. Hovering on 40, but on really really intense fights with tanks, smokes, explosions and lots of people I've experience dips to 26fps.
Less heat
I was cleansing my PS3 (remove dust and on tuesday AS5 TP apply
Then I moved on to my MacBook Pro, removed the fans and removed a fine thick layer of dust Now the GPU temps are down from 91-93Celsius to max 85C and now I've tried 850/1000 @985v runned smoothly without extra heat but was unstable on BF3. but I find 825/975 @985v stable!
Before I removed the dust the Benchmark from Metro 2033 dx11 all set to medium barely hit 22fps with 12fps average
Now it gets 34fps average!
well, now the question is if I want to reapply Thermal paste on it, because I haven't done it. some of you got good experience with AS5 and MBP early 2011?

Ok so im having an issue with ati tray tools. I overclocked to the 800/900 with 0.955 and the numbers coming out are good. Im playing star wars the old republic and after a few the game crashes/graphics card stops working for a few seconds and recovers. Does anyone know what i could do to solve this issue?
I have v-sync on in game and AA+AF both set at x2 on ATT
