I spoke with a technician at Applecare a few days ago about my wife's macbookpro 15" (about 4-years old) it is continually running very hot and I am concerned that it will fall over. The tech said that she might be 'overclocking' - what does this mean and can it be cured?
I have a new 15" MBP(256mb) and was wondering what kind of improvements I can see with doing this. Also can anyone recommend or not recommend doing this for some reason? Does anyone have a link to a good how-to on doing this?
I was thinking of overclocking the CPU from 2.4 ghz to either 2.53 ghz or 2.66 ghz, to make it comparable in performance to the higher end models. I know for desktops it's very silly to buy the higher end cpu, because a little overclocking will give the exact same performance. Anyone knows if the same holds true for laptop CPU. ( I think the i5 2.4 ghz and 2.53 are identical except in clock speed, so a little overclock to 2.53 ghz should atleast be possible right? ) And are there guides on how to overclock on a Mac/OS X?
I'm running my MBP under Windows 7 64bit, and I was wondering how to go about overclocking the GPU/CPU under the Windows environment.I have a 13" so I'm guessing doing the GPU might be pointless but all the same is there a way to do it?
Wanted to let you know that I had great sucess overclocking the 320m in the Air. I used the same procedure found in this thread.

This might help you starcraft junkies out there as it may give a 20% increase in performance. I played MW2 for two solid hours tonight without lockups at 625 / 1340. (11" 1.6 4GB) Thanks go to all in the refrenced thread that contributed to these findings!
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.
-------------------------------GUIDE------------------------------ 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!.

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.
just got my air 11.6 cheapest version. I was playing tf2 under Os X and the performance is just a tiny bit too low for good playing, i feel like a tiny overclock of the 1.4 ghz cpu would greatly help. Considering the core 2 duo is a very mature cpu, and that the laptop doesnt seem to heat that much, it might just work. Of course Im talking about even just a lil oc to 1.6ghz.
Anyone here that's been gaming on their Boot Camp XP partition will already be well aware that Apple cuts the bollocks right off their graphics archiectecture on the Mac side, but there are many ways to overclock those cards from Windows, resulting in sometimes massive performance increases in games/3D apps. I know it's possible on the X1600 cards in the iMac and MacBook Pro; every time I was going to run a 3D game less than a year old, I'd crank the card up from 300/350 to 450/450. The jump in performance in games like Half Life 2 was just immense, going from acceptable but a little shuddery to butter meltingly smooth.
Anyway, I have a MacBook now, and I know Apple restricts the amount of RAM available to the GMA 950 a HELL of a lot, resulting in shockingly, and unnecessary, poor performance in 3D, games in particular. So I was wondering if there was an ATItool app out there I could use to "overclock" or assign bags more RAM to the GMA 950 on my MacBook, on the Windows side, safely and effectively.
I downloaded Catalyst Control Center and the latest XP Pro drivers for the 2600XT from ATI's site. In XP I installed the new drivers and ran CCC's built-in overclocking utility which tests the card and makes recommendations for boosting the speeds. The program recommended increasing the clock/memory from 700/800 to 760/860.
I recently bought a PowerMac G4 1.42GHz Dual Processor. It has 2 gigs of RAM on it. It was a fair deal I think. The "thing" is still looking like new and shiny. Even the insides are still tidy and intact. My question is, would I still be able to pump more juice from this beast. It still run fast comparable to some decent windoze box. Up to how much processor can i be able to squeeze out the CPU and if possible, how to?
It seems that everytime I visit a tech site like anandtech and stumble on CPU articles or discussions, they talk about overclocking. On the latest i3 CPU, the author overclocked the 2.93GHz to a stable 4GHz wihtout even needing additional cooling. Why is overclocking such a big deal on the PC side, but not on the Mac side even though we're using the same family of chips?
if one were to install a xeon with a 1066fsb, would the macpro automatically try to run it at 1333 (in effect overclocking it) or would it automatically shift to 1066? If it doesn't do it automatically, could you force it to do 1333 somehow?
Recently purchased a new desktop so i wouldn't mind tinkering with my OLD iMac G4 1.25G Is this processor just a over clocked 1g G4? I would like to add more ram and over clock it to 1.5g or higher if possible. Is there anyone who would know how todo this? I assume i would need to change jumper setting within the computer right? What would the setting be?
I mainly use this for music and simple everyday tasks and its soooooo slow compared to my MBP and MP.
i have 1.25ghz mdd default jumper settings is like first table now i have jumpers like third table. about this machine shows 1.58ghz now and its unstable so how i get this f..king 1417mhz
I followed the instructions here: [URL]. To do the BSEL mod. My (previously 2.0 GHz) MP booted up after brain transplant - hooray. Eight-core rendering in Cheetah, no problem. However the chips seem to be running at 1.86/1066 (According to Marcel Bresink's Hardware Monitor). If I somehow got the procedure wrong (wrong pin covered, say), should the chips be running at all? If I got the procedure right (correct pin covered) then what are the possible explanations for it not working?
I have a 1.33ghz 1.28gb ram 14" ibook. I have leopard on it and have optimized it as much as possible. Ive got youtube videos running pretty smoothly but there in an online TV service I use that drops a frame every couple of seconds. I was wondering if i overclocked the graphics card by 10% will in slightly improve the playback of flash?
I just restored an old 1999 G3 iMac DV 400MHZ with slot-drive from the dead, and I feel it lacks a bit of power under it's hood. I already put RAM and HDD but the computing power is just not enough. What I want to do is go into OpenFirmware and speed up the cpu and possibly the bus, I remember doing so on my sawtooth but I can't find the code plus that was a G4 and now I have a G3. I also found this page [URL] that shows how to mechanicaly overclock up to 1GHZ but I want to be able to do it non physical if possible. I know this isn't the hot topic now a days but maybe some of you will remember what they used to do and feel some nostalgia(is that a propper word?).
I have a Macbook running Leopard and an iMac running Tiger. I am looking to upgrade Leopard to Snow Leopard and Tiger to Leopard. If I were to purchase Snow Leopard and install it on the Macbook, would I then be able to use the copy of Leopard that came with the Macbook on the iMac? I am not trying to use 2 copies of the same thing on different machines, I just want to put a new os on one machine and move the existing one to another.I am reluctant to purchase the Mac Box Set version of Snow Leopard for the iMac because I do not want or need iLife and iWork.
My Macbook Pro (from mid-2010) has recently started running EXTREMELY slowly, and the fan continuously runs loudly. From other posts, I have checked my activity monitor to see if any process is taking up a lot of the CPU % and have found that nothing seems high, except the kernel_task which, from what I understand, is supposed to be high. I have also attempted to reset the SMC which didn't fix the problem either. I have taken my computer to the genius bar 3 times now, and they keep telling me nothing is wrong (because it works perfectly there), but when I get it home the fan comes back on, and everything runs slowly.
Info: MacBook Pro (13-inch Mid 2010), OS X Mavericks (10.9.2)
My Mac feels as if it is running slower these last couple of months. I have thought of pursuing a commercially available "clean up" product, but thought I would try the community first and also for pointers using the Mac's own internal diagnostics or system improvement capabilities. Any and all advice is most welcome. I have a 250GB hard drive that is half full, I always update to latest revisions and have an extra high-speed internet connection. Computer is not heavily loaded with apps and typically using Firefox for browsing. (MS Office for Mac as well, but usually limited to one program such as MS Word or Excel at a time.) No heavy graphics utilization. Videos from the internet load slowly and some are choppy. Even scrolling just doesn't seem "brisk".
Info: MacBook Pro, Mac OS X (10.7.3), 2.53/4GB Ram
I've had an iMac for just about a year and over time I guess I just didn't notice but the machine always ran very quietly. At the same time the back of the computer would heat up so bad that it would nearly burn my hand if I left it there. Well last week I decided to upgrade to Lion from Snow Leopard and when I did the install failed and froze up the hard drive. I took the computer in to the apple store and they determined that it had to have a new hard drive installed because the old one (only a year old) had a physical malfunction (was broke). So anyway I have my iMac back and get it started up, backed up from time machine, and then finally get Lion istalled - and now all of the sudden I notice that the fans in the computer are CONSTANTLY blowing - I can hear them spinning and can hear the air venting out of the back of the computer - and the computer is STILL really hot on the backside of the screen.
So now I am wondering if the originial problem was the computer heating up and if that may have broken the otherwise good hard drive? Also now that I have a new hard drive - should I be concerned about the fans being on ALL the time? I mean they never go off. Even when I leave the computer for hours and come back to it and the screen is asleep the fans are STILL buzzing away at top speed. Here is the stats on the computer at the time that I'm typing this note - there are no other programs running than Firefox and Mail. Also - I don't know what the optical drive is exaclty - but if it's the DVD drive (superdrive) - there is nothing in the DVD disc drive
my 4 year old IMac 2.4ghz intel core 2 duo with 2gb running 10.7.3 has been running really slow since I installed photoshop CS4 and upgraded to lion ( I have 137gb of free space on hard drive) I mean it wont quit out of photoshop I always have to do a force quit and most applications run really slow. Do I need a new computer , what should I go for to have a smooth running mac?Was thinking of a new IMac 27-inch: 2.7GHz with 4gb memory.
This is the first time I've tried OWC memory. So far, so good - the Mac recognizes the RAM and boots okay. Everything I've tried thus far post-upgrade works. I am a happy camper now - my Mac was a bit sluggish due to running out of physical RAM running Parallels.
