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

Lower the overclock or raise the voltage.

Having the same problem but on BF3, Max I could go w/o it crashing is 790/890
 
yeah, turned AA off and still had the display drivers fail. Im gonna try and set it at 790/890 and see if it works any better. I read somewhere that the game had a memory leak? i dont know if it was fixed though.
 
CCC version

CCC prompted me to upgrade to version 11.12. I'm currently running 11.1 after a lot of trouble upgrading around 11.9. Has anyone installed 11.12 and/or had trouble with it and ATT?

Thanks!
 
I'm not sure what's wrong with my setup. I've got an early '11 MBP 15" with HD6750, 2.3GHz, and 8GB RAM. I installed Catalyst drivers 11.12 on top of bootcamp drivers.

I have almost nothing installed but diagnostic apps (in Win 7 boot camp), but I'm having extreme difficulty getting any meaningful OC or undervolt.

With ATT I tried for (what I thought should have been) a modest 750/900 @ 0.955V, but this black screened. I tried that same clock arrangement at the full 1V that's stock, and that didn't black screen right away, but did about 2 seconds into a run of 3dMark06. I haven't done any real fine tuning, but about the best I can seem to do at or under 1V is 720/875.

Undervolting doesn't work at all either - I tried the recommended 600/800@.855V and that was an immediate bust, as was 600/800@0.9V.

Some other wierd behavior - it seems that when I reapply my stock clock settings, they only "hold" for a little while, reverting back to whatever OC actually took previously after about 3-4 mins. Also, I'm getting a LOT of spikes to the full clock speed, as opposed to the 2D clock speeds of 100/150 like it should stay at. All this even though I'm doing nothing but browsing this forum with no other program open.

Do I have a defective card or something? I just bought this thing and I'm beginning to get a bit of a sour taste.

Best solution for me was finding a sweet spot (750/850 with stock volt for me). From experience undervolting caused stability issues for me so I'd suggest to just leave it stock. I don't use ATI tray tools anymore and I've had more success with Sapphire Trixx.

For the random spikes check within your processes and see whats eating up your usage. + I'd suggest doing a clean install of 11.12

This should be pretty helpful :

Totally unscientific test results! :D

well, it has been over a week since I decided to change the thermal paste :rolleyes:

so before reapplication the temps were usually around:
GPU 85-90 Celsius:
775/875@0.960v
CPU 95-100 Celsius:
TS'd to 2.2ghz

after
GPU 81-85 Celsius
775/875@0.985v
CPU 90-97 Celsius
without TS!!!!

ThrottleStopped to 2.2Ghz
gets the temps to:
GPU: 85-89C
CPU 100C
So I stopped using ThrottleStop, since it's already at 45-60fps :D

but the best part is that on Lion the temps are better ;) doing intensive tasks let's just say Handbrake 1080p :p it hovers around 85C with max at 91C
before that 90-95C with max at 100c :eek: and 45 while sufing the net ;)

btw I use the 12.1a drivers :) and I play Skyrim :p

Folks, Apple's MBP's already run a tad warm because of limited thermal management. ImageImageImageThat said, you introduce OC to the mix and the results may be disastrous. Do yourself a favor, use your beautiful MBP's for what theyre intended for...If you want those ethereal benchmarks on games, build a gaming PC.

Well, the dude with the 98C on his GPU got some serious issues :p
but this is a Overclocking guide, so don't expect to see:
"woow my mac is running perfectly normal, and I use it as a decoration at my desk because, my gaming rig is the perfect pc for me"

not everybody got a place for a gaming rig or the money to have multiple machines... yet in my case :p

and those images of yours does not work :eek:
 
Can't adjust voltage or use ATI Tools

Hi, I just setup my computer via boot camp and attempted install and run ATI Tools to overclock but ATI Tools gives me a display driver error and MSI Afterburner won't let me change anything. What have I done wrong?:eek:
 
How much is the overclocking improvement? 2-3 more FPS?

For me, using the 800/900 MHz @ 0.955V, I get ~20% higher framerate, verified using the Adrenaline Crysis 2 benchmark. Definitely enough to knock the graphics settings up a peg in demanding games.
 
Can anyone walk me through removing the boot camp video drivers and installing the catalyst drivers fresh? The method I tried actually screwed me up to the point that I couldn't install drivers at all and I ended up reformatting windows.

Since I couldn't directly uninstall the drivers via the windows software uninstaller, I went into the device manager and selected the video card, then uninstalled drivers there, followed by a reboot and install of catalyst drivers (11.12). Problem is, the Catalyst drivers apparently couldn't detect the video card and they never installed correctly. Then I was stuck with 640x480 res and I couldn't get anything to work.

Any tips on this? I'm not sure what I did wrong.

make sure you download the mobility version, direct link: 11.12WHQL got it from Guru3D's 11.12 forum
download the driver, when installing choose to uninstall, then use Driver Sweeper
then install the driver ;)
 
I see a lot of data for 6750M 1GB but not for the 512MB version, could someone post some results for the Late 2011 2.2Ghz model too? Overclocking capabilities, maybe some BF3 and stuff.
 
I have a late 2011 MacBook Pro (i7 2.2GHz | 6750M w/ 512MB) and I'm having some problems with this.

I tried the recommended settings (800/900 @ 0.955V) and 3DMark ran fine, but whenever I ran GTA4, it would either crash a few seconds after I opened it, or the screen would turn gray and freeze after a few minutes of gameplay.

So instead, I tried 775/850 @ 0.955V and had the same problem, but then I got a couple BSODs as well.

Does anyone have any recommendations for what to try next?
 
try different game. update drivers.
not all units can be easily overclocked. you might need to reapply thermal paste if your laptop is running too hot.

Got the 512mb version I OC'ed to 750/800 and I get some pretty impressive results. Although, what I noticed was I had an increase of fps when I downclocked from 850 to 800 (probably unstable at 850). I'm guessing the OC capabilities aren't up to par with the 1GB 6750m. Never tried increasing the voltage yet. This was all done @ stock
 
wish this would work with Mac OSX. i dont like switching back and forth from windows. plus Windows is ugly as hell compared to mac os

The games I play that would benefit from overclocking are only on Windows anyway...
 
Has anyone tried this tweak in Battlefield 3?

"create a file named user.cfg in the same folder as bf3.exe and put the following line in it
WorldRender.DxDeferredCsPathEnable 0
it gives you a boost of 7-10fps. then turn the in-game MSAA (deferred anti-aliasing) off and use the in-game FXAA (post anti-aliasing) instead. it gives you another fps boost with the same overall image quality."

Wondered what the of boost it gave.
 
I need help I'm running 15" macbook pro 2.2 quad i7 with 6750 1gb ATI Tray Tools just crashes every time I overclock and msi afterburner won't let me move past my default clock speed!! Some one please give me some advice!!
 
Hey guys - I'm seeing some odd behavior:

Ran 3DMark06 with stock settings (600/800/1v) last night and got about 8000.

Changed settings to 700/900/.955v and re-ran 3DMark. Was very surprised to see my score drop to 7300.

Changed settings to 750/950/.955v and re-ran 3DMark. Again, got 7400 or so.

Put settings back to default and re-ran, getting around 8000 again.

Anyone have any clue whats going on? I was monitoring during each test, and temps were quite low (mid to high 70s). I verified that the clock rates I had set were functioning.
