MacBook Pro :: Unable To Switch Between Intel HD And 330M Graphics?

My new MBP 2010 won't use Intel HD graphics, it seems stuck on the 330M graphics card with no programs running at all. I also checked the power saver option for auto-switching graphics.. What to do?

It worked before I calibrated the battery, but today when using the MBP for the first time since calibrating it won't switch.

MacBook Pro :: Graphics Automatically Switch Between Two Cards
I recently purchased a 15 inch Macbook Pro (model with both an integrated and dedicated graphics card). I was under the impression that switching between these two cards required me to log out first but was wondering if there was any way around this. I noticed in system preferences that I can configure different energy saver settings for the computer for when it's plugged in versus when it's running off its battery. If I set the graphics to higher performance when the computer is plugged in and better battery life when it's not, then does that mean that the graphics will automatically switch between the two cards when I plug or unplug the computer or does this switch still require a logout to take effect?

MacBook Pro :: How To Manually Switch To 9600 Graphics
I heard that to enable the faster graphics, you have to log out and log back in to switch between 9400 and 9600... Is this true? If so, is there any word on when this will be automatic or if there is any current work around?

MacBook Pro :: New I5 Cannot Switch Google Chrome And Graphics
After installing adobe cs5 on my computer, gfxcardstatus has been going crazy changing between intel and nvidia graphics. I happens at random, while using google chrome. For instance, the front page o [URL] triggers the nvidia graphics to come one. When i navigate to these forums, it switches back to intel. When I log into gmail, its fine, until gmail signs me into gchat(i disables video chatting b/c i know that was a known issue with turning on the nvidia card)

MacBook Pro :: Screen Not Working - How To Switch Graphics Card
Apparently there was liquid damage, but I have no idea how this could be as I've always looked after, but I trust their judgement. Anyway, I put it down one night, next day it wouldn't start. However, the one thing I did do the night before was switch graphics card for the first time in ages. It worked fine afterwords or so it seemed.

To cut a long story short, it seems to be still fully working except for the display. I can't afford to get it fixed yet (700 repair bill!), but I'm thinking if I can switch graphics cards somehow the screen might work again.

MacBook Pro :: How Often Someone Switch Graphics Cards On Regular Basis?
I'm interested in seeing how many of the people that own a unibody Macbook Pro switch graphic cards on a regular basis. I know when the unibody Macbook Pros came out people were complaining that switching graphics cards required logging out. Is this still an issue or do most people stick with one? I just switched to the 9600M after being on the 9400M for about two months as I needed the extra power and battery life wasn't an issue.

MacBook Pro :: Shortcut To Switch To 9600M Graphics Card?
I like to keep my laptop cool, so I usually run on the integrated 9400 graphics chip. But lately I've been finding myself playing a lot of games on my unibody mbp. However, it gets kind of tedious to have to continually switch over to the "better performance" 9600M option in energy saver. Instead of opening energy saver, clicking "better performance" and then restarting, is there a simple applescript or shortcut I can just double click that will do all this for me? I'd like to just place that script on the desktop and call it "play games" or something." I know it's a small inconvenience, but does anyone have a solution? Or can anyone make a simple automator or applescript to handle this?

MacBook Pro :: App To Show Intel HD / 330M Status?

MacBook Pro :: Can't Find Switch For Graphics Card Setting
I just got my 15" MBP today and I can't seem to find the "Longer battery life or Higher Performance" option. I have downloaded all the software updates and still can't find it. I looked at the online tutorials and my "Energy Saver" options doesn't show the buttons to switch Graphics performance.

MacBook Pro :: Cannot Switch Video Cards In Graphics / Display Section
On the Energy Saver pane, I have the choice between 'Better battery life' and 'Higher performance'. And I can click the latter, at which point a dialogue comes down saying "Please log out for this change to take effect." I do so. When logged back in, however, I open System Preferences again, look at the Energy Saver pane, and although the "Higher performance" box is checked, it says next to it "You need to log out for this change to take effect". However many times I log in or out and check the box, that always happens. And the Systems Profiler shows only the "NVIDIA GeForce 9400M" (in the "Graphics/Displays" section"), when I believe the correct card should be "9600M GT". In fact, I thought that both cards should show up all the time.

MacBook Pro :: No Interface To Switch Graphics Mode On System Restored From Backup?
As a result of an emergency, I recently purchased a unibody MacBook Pro 15" to replace an older MacBook pro. Because of a time constraint, I restored a SuperDuper! backup onto the machine in order to continue my normal work immediately.

Everything works as one would expect; all of the hardware is detected and works correctly. Even the preference pane for the trackpad automatically changed to reflect the OS's awareness of the new multi-touch trackpad.

MacBook Pro :: Desktop Background Picture Disappears On Graphics Card Switch?
I have a custom desktop picture, and every time my graphics card switches from the Intel HD to the nVidia 330M, my desktop picture disappears and becomes a sold blue background. No functionality is lost like I've read in some other forums, it's just solid blue. I have to go into settings and reset the picture for it to come back. This happens anytime the graphics card switches, even opening iPhoto. I gave the gfx card status program installed...It seems as though the picture only stays with one graphics card. If I change the picture back to what it was with the nVidia card is running and then close iPhoto or whatever app caused the switch, when the Intel HD card kicks back in, the background will turn blue again. Anyone know how to fix this?

MacBook Pro :: Mid 2010 Won't Switch To Nvidia Graphics?
I have been playing Starcraft II on my Macbook Pro (i7/4G RAM/15" Display) for a few weeks now. Yesterday my frame rates dropped through the floor. The game was nearly unplayable. I thought initially that the level I was playing just had too many units. I re-played one of the tutorial levels and it too was slow. I lowered the graphics quality settings in the game and it didn't get much better.

I put the game into windowed mode (rather than full screen) and started playing. I pulled up the system profile tool and saw that the intel graphics were active, not the nvidia graphics.

I went into system preferences/energy saver and shut off automatic graphics switching and it was still using the Intel HD graphics.

This happens all the time, plugged in or not.

MacBook Pro :: Finding 2.4 Core I5 15" Graphics Card Switch Flicker
This is my (second) first post, and I tried using mrooogle to find the issue (i've been a lurker for the most part) I can't seem to find any consensus or info on it.

I have the 2.4 core i5 15" MBP with HR Glossy display, just got it on Monday, installed an owc ssd, and 8 gb of ram and i LOVE IT. The only issue is when the graphics card switches from the nVidia back to the Intel graphics, the screen briefly blanks out or "blinks" for a split second and the Intel graphics comes back on. It doesn't blink when it goes from intel to nvidia, only from nvidia back to intel.

MacBook Pro :: How Much Better Is 330m Vs 9600gt In Regards To Games?
Right now, I have a 2009 MBP with 2.66 core 2 duo and the 256MB 9600gt. I am looking to buy a 17 inch i5 with the 512MB 330m. With regards to gaming under bootcamp, how much better is the 330m to the 9600gt? Will I notice a big difference in my games or will it be barely noticeable? I tried to play black ops under bootcamp and it was barely playable.

I did not send any private info during that time, any risks of getting hacked?

MacBook Pro :: Gaming On 15" MBP I5 Or I7 With GT 330M?
I'm thinking of getting a new MBP, but want to be able to play MMORPGs like Warhammer Online or similar games coming out. Can anyone speak to first hand experience with the various 15" MBPs with i5 or i7? With 256MB GT 330M vs 512 MB? I would love to be able to get the 13", but I'm sure that video card won't make it happen.

MacBook Pro :: 330m 256mb Versus 512 Mb?
So I just sold my MB and am going to be upgrading to a MBP. I have been reading up on the current ones and have seen that almost everyone reccomends going with the 15" 2.44ghz vs the 2.66, as the ~$400 difference is not justified. What still sways me towards the higher end 15" is that the 330m has 512mb vs the 256mb in the base model. I will be using it for games such as The Sims 3, Civilizations, and SC II. I will also be using PS as well. Will I notice a huge performance difference between the 512 and the 256?

MacBook Pro :: 330m BootCamp Overclock In Win7
I know a couple guys in the MBP refresh gaming thread were able to overclock using Nvidia Tools. I'm not having any luck; the sliders are grayed out and I can't make any changes with system tools 6.06. I've also got errors when trying to install Nvidia drivers other than the ones included with Bootcamp. What driver/system tools version are you using to OC? And what settings have you tried? (I'm on Windows 7 64bit).

MacBook Pro :: Won't Use Always 330M / Plugged In
My 2.4ghz i5 MBP runs a lot better when using discrete graphics. Minimizing and maximizing windows, scrolling, opening folders etc... all run smoother with the 330M. Is there a way to always run the 330M when plugged in, and switch to automatic graphics switching when unplugged? This would be the perfect solution for me.

MacBook Pro :: Overclocking The GT 330m Guide - Benchmarks
I would first like to start off with the disclaimer that I am not good at writing guides and I am also not a pro with overclocking but here is my attempt at both. Also I am not liable for damages to your computer and ask fobis has mentioned each gpu even if they are the same may overclock better or worse then the next. So take my overclocking numbers for what they are worth. Experiment and try it out on your own.

Note: This guide assumes your running Windows 7 64bit, and also it assumes that you are new to overclocking.

1.First make sure you have a copy of windows installed through bootcamp.

2.Then go ahead and install the drivers that came with bootcamp ( we won't be using the gpu drivers but the rest are going to be useful anyway so might as well go ahead and install them )

3.After you have all that you will want to go here to get a modified driver. This will give you better performance then the bad drivers that apple supplies it will also let you overclock the gpu

4.After you have downloaded both the driver and the INF file open up the driver and it will extract the files to the directory that you choose. It will also try to launch the install but it will fail saying something like " no compatible hardware found " ignore this for now.

5.Now take the INF file and copy it to the folder that the driver was extracted too. It will ask you if you want to overwrite the file just say yes.

6.Now open up the device manager by right clicking on my computer, selecting properties, this should open a new window and on the left there should be something that says device manager.

7.Under the tab that says "display adapters" select the only device that shows up on that tab. Right click it and choose uninstall.

8.After you have done that it will likely mess up your resolution and set it too 800x600 don't worry this is normal. Now just restart your computer.

9.Once you have restarted when it starts back up it will say new hardware found. Now you have to choose to install it manually choose the option that says something along the lines of " search for drivers in specified area "

10.Now it will take you to a new page and on that page there should be an option that says "have disk" choose this and select the directory that you extracted the driver too earlier in this guide. It should find one of the files that it can use and install it just fine.

11.You will need to restart again once this is done but when you start back up your resolution should be fixed if not just right click and hit screen resolution and just change it back to the native resolution.

12. Download Nvidia system tools found here

13. Go ahead and install this it should be self explanatory.

14. Once it is installed open the program and go to the performance tab on the left. ( It might ask you to agree to some terms of use )

15. Just put in these numbers and hit apply
646 for the first one
864 for the second one
and 1314 for the third one

Now your done if your paranoid like me of overheating your computer you can also optionally download and install LubbosFanControl to max out your fans to keep it as cool as possible.

Enjoy your faster GPU!.

Before OC:
FPS: min=13 max=22 avg=15
Crysis: 24.89
Unigine Sanctuary Demo (run with everything on defuilt excapt resolution turned down to 1280x800 )

After OC:

Points: 1081
FPS: min=16 max=26 avg=18
Crysis: 33fps
Unigine Sanctuary Demo (run with everything on defuilt excapt resolution turned down to 1280x800 )
DX10: 31.2fps (scores: 1322)
OpenGL: 28fps (scores: 1211)
Unigine Tropics Demo: (run with everything on defuilt excapt resolution turned down to 1280x800 )
DX10: 21.7fps (scores: 546)
OpenGL:19.8 (scores:498)
Unigine Heaven Demo:
OpenGL: 16.2(scores:408) WTF? OpenGL wins? lol
3DMark Vantage: 2922

Notes: Crysis was run at 1280x800 everything on medium excapt physics on very high

Another note: The highest GPU temp underload from Crysis got up to about 78C after about 15mins of running the game. Furmark got the temp up to 80C though after about 15mins also.

I have also played TF2 at max settings @ 1920x1200 for over 2 hours to test stability and it ran fine without any hiccups

Also I feel that this card can be pushed further then this ( I have not tried ) but from what I see it cools a lot better then I expected from a laptop I come from a world of desktop overclocking.

MacBook Pro :: Nvidia 9400M Vs Geforce 330m
The 9400M was in older Macbook Pros and I've seen many videos where people run crysis on high/very high and have pretty good FPS. The laptops arent as fast as the newer ones, but yet my MBP (specs down below) which is faster, can only run crysis on medium at around 30 FPS, unless i wanted 5 FPS with high. The only reasoning for this, to me at least, is that the 330M chip is not as good. Is this the case? If so, why the hell did the graphics chip get downgraded? Here is a link to one of the vids I was talking about: [URL:....] This guy is using the demo for his vid. when i use the demo, it doesnt even give me the option of using very high settings, and when i'm on high, my screen flashes in and out, i get random lines across the screen, and then my computer freezes.

MacBook Pro :: 330M Overclock (Without Windows) - Discussion
I'd like to know how many over clock their 330M and how much. Somebody without Windows, who hardly ever plays any kind of game probably doesn't over clock but there are probably many that do play but still don't over clock. The only game I am playing now is Modern Warfare 2 and over clocked the 256mb 330M offers about 25% more performance. That is the difference between 25 and 30 fps. I found that temps don't really rise. At default the GPU reaches about 70C and the CPU around 50 (idle is 32-40). Over clocked 645/808/1451 it avg 73C and CPU is a little lower on 48-49C because the fans work a little harder while the CPU has the same amount of work. That sounds pretty cool to me and I didn't even test any higher, because usually a notebook GPU is a cool chip that over clocks well as long as it is cool enough, and desktop GPUs on the same silicon sometimes run standard on almost 90C. The max temps are higher with 82C which it reaches after game start for a short period until the cooling really kicks in. There is no fan control prog running. That is a 30% increase in clock speed with almost no increase in temps.

I don't know how to read out fan speeds in windows but I don't notice the fans from in the loud gameplay anyway. What are your clocks?? I don't like benchmark tools as they don't determine what matter really to me. I know with furmark I get higher temps but I am not running furmark for fun ever. I play CoD. I used in the game (Call of Duty MW2) in Act 2 of the campaign the misson "of there own accord" because it is probably one of the hardest with the lowest min framerates. I get stock 24-25 fps running outside and min 22. Inside it is 33-60fps. Over clocked it is 28 min 30-31 outside and 38-120 indoors. I use native res (high res) but no AA and no soften smoke edges because it kills performance in some scenes and I don't see the difference. Everything else is on the maximum I can switch it to and the textures are high. AA is only missing in some levels with high contrast where edges start flickering a lot but in general I prefer the higher res over AA. It is just more detail and easier to see the enemy.

MacBook Pro :: Nvidia 330M Used When PowerPoint 2011 Opened
Just got the new office 2011 which I use every day for university, primarily the powerpoint program for presentations and note-taking. Today I noticed that my battery drained more quickly than usually and found out that I use the nvidia 330M when powerpoint is open. Just did some research and neither word or excel makes the MBP use the 330M. Only powerpoint. Is there any way to force the intel gfx on all the time? Or at least when running on battery?

MacBook Pro :: 330m Freezing Randomly During Playing 3d Intensive Games?
I have a 2010 2.4ghz 15" Core i5 MacBook pro with the high res screen. Recently I noticed that the MBP may randomly freeze when 3D games are run under bootcamp. By random I mean ranging from 30 min to 2 hours into the game. The screen would distort into vertical lines and a buzzing/static noise could be heard coming from the speakers. However, I've also noticed that while the keyboard and mouse seem unresponsive, Skype calls would sometimes still be audible and connected despite the rest of the system freezing. I have yet to experience this in OS X as I rarely play any 3d game in OS X. I have updated both the OSX and Windows drivers to the latest version. The problem is persistent and happened in star craft 2 and red alert 3. What seems to be causing this?

MacBook Pro :: GPU : 9600M @ 512 Versus 330M @ 256
I currently got a late 2008 MBP with the 9600M with 512 Mo VRAM.

I got sick of that glossy screen and that's why I've stepped towards the i5 Anti glare.

Anyway I'd simply like to know if I'm about to loose some perf with the new GPU having only 256 Mo VRAM compared to my old 9600 with 512.

Concretely, I'll be playing Starcraft 2 on my MBP's screen, so no external screen and huge resolution.

Do you think it'll be better with the i5 spec ? Same ? Worse ?
