MacBook :: Overclock / Improving Performance Of System
Sep 6, 2010
I've come into possession of a 1.83 Core Duo MacBook and I am curious if you're able to clock the processors on these in anyway? I appreciate the implications of doing this on a laptop / notebook type device, but I want to know in theory if it is possible. I understand the maximum ram on a MA254LL/A is 2GB... is this correct? Will it not ready any more? In terms of the CD drive, is it possible to upgrade it to a superdrive? Is this easy or simply not possible? I've seen a few on ebay, and would be curious to know if they'd work. How far can you get with a MA254LL/A, whats the maximum HDD you could pop in?

I am sort of shocked how much low I/O performance mars overall responsiveness of my mp. Whenever I have some disk intensive app running the entire system begins to stall awfully up to the point when a simple task such as browsing becomes a painfully slow process. This situation is even aggravated when I concurrently access a flash drive. I have 4 Samsung 1 TB F1s and 8 GB RAM available. Would building a software raid 5 help to improve the situation? I reckon that transfer rates are part of a problem. Intels latest SSD Drives are also much faster than my F1s and also sport much better access times. Has anyone experimented with using such a drive as the system and application drive?

Is there any way to improve the video performance on my iBook G3 (600mhz, 640MB RAM, 16MB VRAM)? I find that besides not being able to play any of the HD trailers at Apple's website (even 480p), it can't even seem to play a standard trailer without stutterring. Is there anything I can do to improve the video performance?

I'm running W7 ultimate on a Rev. A MBA. I'm looking for some tips on improving performance in Bootcamp.
Here is what I have done so far:
- Installed latest BC drivers (3.1)
- Defragged windows partition
- Disabled hibernate function (to save HDD space)
- Installed all updates from Windows Update
- Disabled (some) of the Aero eye candy
- Disabled unnecessary services (ala Blackviper's site)
- Disabled unnecessary startup programs
EDIT:
- Disabled Index Service
- Disabled Windows Search
My main reason for wanting to do this is that I'm having some issues when playing MP3s in WMP. They play fine until I say, launch Firefox. Doing so causes the playing MP3 to skip, or temporarily become garbled. I assume this is due to taxing the HDD, but since upgrading to an SSD is currently not an option, I'm trying to squeeze as much performance out of the system as I can.

My home WiFi network is currently very unstable. I'm working to improve it and looking for a little advice. This is a little long but I'm trying to provide as much relevant info as possible. First, I have Comcast cable internet performance package (6mbps). My internet speeds vary from about 3-10mbps. I use the Comcast provided cable modem (rented). From the cable modem I run a cable directly into an Airport Express 802.11b/g to create my home wifi network. I have a usb printer attached to the Airport Express for network printing. I have a second Airport Express on the other side of the house used to expand the network and pump music into my home stereo via air tunes.
I use my network for general internet surfing, airtunes streaming to my home stereo, and itunes and bittorrent downloading. No gaming or other speed intensive applications especially within the home network. I have two problems - the internet drops out and requires a reset very often - at least once a day and the airtunes is very unstable. For the internet problem, I thought it was the Comcast internet but I've checked the quality of the cable signal and removed all unnecessary splitters, etc and it still happens. I think the problem is my Airport express. For the Airtunes problem, this clearly seems to be an Airport express problem. I'm thinking of going to a Linksys WRT54GL 802.11b/g as my primary wireless router and purchasing a cable modem (to save money in the long run over renting.)
Here are my questions:
1) Based on my usage and my current Comcast internet package, my understanding is that 802.11b/g is fine for me. Is this correct? I don't think I need or could benefit from the 300mbps speed of a N network.
2) Can I still use the airport express for airtunes and printing on the Linksys WRT54GL 802.11b/g network?
3) Regarding the cable modem, is there any advantage to getting a more expensive DOCSIS 3.0 modem such as Motorola SURFboard SB6120? I've read that some people see significant improvements in their speed even if they have a slower internet service.

I have a 2009 2.53GHz MacBook Pro which I bought a couple months ago. It's been working great, but lately, I've been noticing a lot of strange issues with video playback/general graphics and UI. These includes:- Laggy video performance, frame skipping, generally 2x slow video -- on both iTunes and web video. It's not as smooth as it used to be, though admittedly not totally unbarable - VLC shows a black screen, doesn't show the video - Randomly pixelated icons in the dock (it's almost like the Mac picks a new one everyday to pixelate), dock animation not 100% smooth, although fairly good (not sure if it used to be this way)

I got a program called "gfxCardStatus" that allows me to see which graphics card is being used and allows me to manually switch between them. I don't do anything graphically intensive in OS X (I only play games in bootcamp) but the nvidia card is being used most of the time and it makes my mbp hot and kills the time i can use the battery. I switched my MBP to only use the intel card in os x and have seen no performance or visual difference, but I was wondering if this is a bad idea?

I have a Acer laptop before and I believe it was infect once. The viruses went away after about a month. Now I have all the files from that PC on a Seagate 1TB external hard drive. I have connected to my MBP a few time but now I am worried that those files might still be infected and that it will damaged my MBP.
1. How to find out if those files are infected and,
2. Will those files infect my MBP's performance, security, software and system.

I have an external USB drive attached to my iMac. I've noticed that whenever there's heavy read/write activity on the drive (such as un-raring a large file or transcoding a video that's stored there), my whole system feels sluggish.

My system (sig) has been relatively sluggish for a few months now. Right now I've only got Firefox, Snak, iTunes and Adium open and it's just prodding. It has a decent amount of ram that should be able to handle relatively easy computing like this.
So, my question is, what can I do? Should I just re-install? I wouldn't really mind doing that. I have all day off, and fresh installs are fun but I have a good amount of stuff on here. I have an external where all of my important stuff is, so a fresh install wouldn't be a bad idea in that way.
This machine is pretty old but I'd like it to be snappy like it once was.
Are there little things I can switch off or something?

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).

I searched, but didn't find anything too specific on here. Can anyone recommend some good overclock values for my 9600m in bootcamp using nvidia tools? Basically, I'm looking for a stable profile or some recommended settings you've been using to overclock your 9600 in bootcamp. Maybe upload a screenshot like the one below with your custom adjusted settings for memory, core, and shader clocks. I'd rather not play around with it if someone has found a fast/safe setting that increases performance.

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.

1) Can you boot into XP and/or Vista (using bootcamp) from the SATA ports on the system board?
2) What are the transfer rates (input and output) on these ports?
3) Does using these ports in conjuction with a Mac Pro RAID Card affect the transfer rates/latency of the drives connected to the RAID Card?

Got a maxed out 24" iMac on the way (3.06GHz Intel Core 2 Duo, 4GB Memory, 1TB Hard Drive) which will be arriving in 2 weeks. Just wondering if there is anything I can do to optimize performance and pro-long life on my iMac ready for hardcore music recording and editing, HD Video Editing, Photoshop, Web Design and Flash? Would it be wise to run every single process included in the Onyx application as soon as set up is complete or should I wait till Applications and Music have been installed? Anything else to do to maximize performance and life of the iMac?

Just upgraded to a 27" quad-core iMac yesterday and I noticed the startup time is much slower than it should be once I migrated all of my files from my old 24" iMac over. I usually keep my system up for months at a time, so startup time isn't an issue, but the question is: Does a slow startup time indicate that once I'm up and running, the system could be much quicker, too, or is that slow issue solely restricted to just the startup time?

I recently installed the new OS X on my MacBook 13" (the 2Ghz Dual Core white one) hoping it would increase the performance of the system, and specifically iTunes. [URL]. My iTunes library, like many out there, is large, but not overly large and definitely not to the point where it should be a problem. It's now at (I would guess) about 30 or so gigs, filled with mostly large MP3 files (70-200Mb).
- It's got to the point where I wait 3-4 seconds to go to the 'next' song when I press the 'right' arrow. This is (obviously) unacceptably slow. I thought about upgrading the RAM of the machine since it only has 1Gb I think. Now can anyone guarantee that doubling the RAM will properly increase performance again up to the point where I don't want to throw the machine out of the window? Yes, of course it will increase performance, that's obvious. But will it be enough, if not, I'll wait until it's completely unworkable and buy one of those new babyproof MacBooks (Edit: Or 4Gb?)
- The library is on an external 1Tb USB2 drive, but I could easily move it to the MacBook's HD but that's slower than the USB2 drive. Would this help any bit?
- Would removing all CD covers and images I have in there significantly increase performance?

First time user of the forum. About a year or two ago, I acquired an older Mac G4 AGP from someone who said it was "broke" and was going to recycle it. Turns out the OS just needed to be re-installed, so she is up and running. I initially installed Leopard, but it didn't run as well as I would've liked, so I put Tiger on it (running much better). After that, I maxed out the memory @ 2GB(4 x 512MB PC133). Then I installed a 7200RPM HD to replace the slower drive. I also installed a DVD R/RW and maxed the processor to a 1.8GHz single core. Right now, I'm looking to bump up the video card. It's my understanding that the 9800 is best card for this system, but I'm not looking to spend that much. I will only be using this system to stream music from Grooveshark and Pandora, so it needs to run Flash content well. Currently, it has the ATI Rage 128 Pro with 16MB VRAM, which is next to nothing. Like I said, I don't need a crazy card, but I'm not sure the difference between one 64MB card and another, or should I go up to 128MB.

Can anyone suggest which would be my best option for external backup? Would a RAID setup be good? I have two exactly the same hard drives laying around collecting dust, and would like to put them to use for an iMac. Could someone recommend a good external enclosure for these two? Which would be better - FireWire or USB2.0? I'm also interested in mirroring since I'd store important data on them, and want both drives to have a copy of each. Is there a disadvantage to that in terms of system's performance?

I just moved into a new apartment today. Of course, I checked to see if there were any open wireless networks before signing up for high speed internet access.
There is one open linksys available, but I am having trouble with it. I get varying signal strengths between all and no bars. They vary as I sit at the table motionless with nothing moving around me. I get high speed streaming audio for a few minutes, then no internet at all for the next 5 minutes.

I am running windows 7 on my new MacBook Air, this is a requirement for my work, so can't be changed. I bought the MBA because it's a beautiful laptop, thin and light, great screen, and great keyboard. My battery life, however seems to be terrible, especially compared to statistics I have seen on other reviews/threads. At the moment, when I am unplugged, I have brightness at 30%, I have the hard drive set to sleep when not in use. I have bluetooth turned off and WiFi on. I almost exclusively use the computer to work on google docs. So, turn on the computer, work for half an hour, in Chrome, either sending and receiving emails or writing in Google Docs. (I can't figure out if this qualifies as "light browsing", but based on my battery drain I would say it's not...) I have a plug-in to block flash, and haven't been running flash on any website since I started using the computer.
Here are my statistics:
Last night, typed (on the web) for half an hour and went from 100-80% battery.
Put the computer to sleep for 9 hours, and when I woke the computer it was at 74% battery.
Typed and checked email for forty minutes, went to 57%
Woke the computer two hours later and was at 49%
typed (on the web) for half an hour and was at 29%
put the computer into hybernate, turned it on ten minutes later at was at 27%
I've now been typing for about half an hour and I'm at 15%.
I'm losing, roughly, 20% of my battery for each half hour of typing in a browser, with flash disabled. That means 2.5 hours of browsing. I need to get 4 hours if I'm going to keep the computer.

I am trying to send a wide format poster file to Staples and the error keeps reading that the quality is too low. I have tried formatting it to .jpeg, .tiff, .png, .bmp, but nothing works. I have determined that it must be the original export to .pdf that is the trouble. I have tried to create a .pdf file through the print option on iPages as well as through the Export option to formulate a .pdf file. The end result seems to be the same. Does anyone know how I can increase the quality of the .pdf file.
If there is a program out there that I can download to create a higher resolution conversion? Is there someway I can make the conversion to one of the files listed above higher? or am I right in thinking that the problem lies with the original .pdf conversion? I need to get a banner poster done by next weekend so I was hoping to get this issue resolved over this weekend. Most of the information on the file is just pure text and gradient fills. I even tried removing the three head shots to see if the photos were the problem...but nope.

my Mac Pro has a very weak wireless connectivity � 4-10% packet loss on average, so I want to try to upgrade it's Airport antennae (I've had the same issues on my PC before I bought Mac Pro, I fixed them by upgrading the antenna).
Does anyone have any experience with external antennae for the built-in Mac Pro Airport card?
What are the plugs in Airport called? (RP-SMA � is that right?)
Are there any converters to RP-TNC, so I could plug a normal external PC antenna? Will there be any problems?
