IMac CPU upgrade

I'll just get to the point.
I have a mid 2009 iMac9,1 system. 24" display w/ 2.66GHz C2D with 4GB of RAM and a GeForce9400M.
I want to upgrade the CPU from 2.66GHz to 3.06GHz (or better if available) since I often run demanding applications such as Flash CS4 and MU:LAB (audio workstation) and the extra CPU grunt would be fantastic.
Is the CPU in the iMac9,1 soldered or socketed? Will the Apple store do it for me? I don't want to tackle it myself as I have never taken apart and Apple computer before.
Thanks.

is the CPU in the iMac9,1 soldered or socketed?
Soldered.
Will the Apple store do it for me?
The Apple Store would not perform such an upgrade even if the processor was socketed. Apple does not support processor upgrades in any of their current Macs (they haven't supported a processor upgrade for years, in fact). The only upgrade Apple will perform on an iMac is adding additional RAM.
Sorry, but if you want a system with a faster processor, you'll need to sell your current iMac and buy one of the current models. The Core i7 system is the fastest, but the Core i5 is pretty fast and significantly less expensive.

CPU upgrades

I'd like to upgrade a tray-loading iMac with the CPU from one of the faster slot-loading ones - 350, 400, whichever.
I'd also like to swap a 450 or 500 MHz CPU from a DV SE that had firewire into the earlier, ordinary slot-loading version, which didn't.
Does anyone know if there's any reason there would be a problem doing either of these changes?
For that matter, if the DV motherboard's okay, any reason I couldn't use the whole thing in the slot-loader? I think there's a video problem, but if that's just a monitor thing and not on the board, it shouldn't be an issue.
Thanks

you are correct, the slot loaders do not have a separate CPU card, its soldered directly to the logic board.
There are CPU upgrades available for tray loaders (don't know if any are actually still produced anymore, but they do exist), but the cost usually just isn't worth it. You could get a used slot loader for the same amount,a nd a used eMac or mac mini for a little bit more.

Check this out : Daystar, Inc. for CPU upgrade! Reliable?

I recently bumped to a highly tempting news : it is now possible to upgrade my iMac FP 17" 800MHz to a faster 1.35GHz, along with larger internal HDD, RAM and Optical Drive. The only option not available is the Video Card (they say it's on-board by default and cannot be replaced).
A company named Daystar offers a low-cost CPU upgrade for the following iMacs (the right-hand GHz is the available upgrade specific to each model):
15" 700MHz to 1.35GHz
15" 800Mhz to 1.35GHz
17" 800Mhz to 1.35GHz
15" 1.0G to 1.92GHz
17" 1.0G to 1.86GHz
17" 1.25G to 1.92GHz
20" 1.25G to 1.92GHz
They say the upgrade is available for as low as $449.00. For additional options additional cost would apply, but anyway. I wonder if anyone had heard this before?
Here's the link to Daystar, iMac FP upgrade section.
http://daystar-store.com/index.asp?PageAction=VIEWCATS&Category=732
I mean, this really sounds sweet but how reliable is this? I thought iMac was basically a non-upgradable system, except for its external RAM and Airport(Express) network card. Pretty impressive, though. Surely worth a glance for those of us considering serious upgrade (like me).

Hi,
FWIW....
Modifying some thing that was designed for a very specific purpose usually ( in my experience ) leads to problems further down the line. The excess heat may cause problems. Taking the thing apart and re-assembling may lead to others. Buying a newer, faster machine seems a far safer option - To me at least!

AMD Athlon 64 3800+ cpu upgrade to AMD Athlon 64 X2

Hello everyone,
First of all, I have been to cpu-upgrade.com and typed in my current (CPU)--> AMD Athlon 64 3800+ 2.40GHz (motherboard)--> ASUS A8M2N-LA (Naos) GL6.
According to the website, my AM2 Socket (940pin) is capable of upgrading to a Dual Core, Anyone know if that site is accurate or not? Any help would be nice. I need to get away from this single core.
1) Some CPU models require a BIOS upgrade, which a BIOS upgrade for this board is not available.
2) A lot of X2 Dual Cores work either using a 4400+, 4600+, and so on....
I do have a 550watt PSU installed, also I am using MSI Nvidia GeForce GT620 PCI-express 16x graphics, not using onboard.
I have read that some BIOS' upgrades terminate the onboard video, is that true? Basically, whatever I already have installed is current and up to date with all video/sound drivers, etc... If anybody very knowledgable knows for sure if an AMD Athlon 64 X2 will work in my system that would be nice. My specs below......
OS: Windows Vista Home Basic (32bit)
CPU: AMD Athlon 64 3800+ 2.40GHz
RAM: 2GB (GDDR2)
PSU: 550watt (all 20+4 for main cable to motherboard connected using all 24 pins + 4pin connector for CPU? I believe.
Sound: Realtek HD ALC888 High Definition Audio
Video: MSI Nvidia GeForce GT620 (GDDR3 with 2GB Video Memory).
Only thing I am bottle necking on is the CPU, and I would love to upgrade to Dual Core, once again, thank you for the help.

Hello @bigsnake,
I understand you are looking to upgrade your processor on your Compaq Presario Media Center SR2013WM Desktop PC. I am providing you with a link to a CPU-Upgrade thread concerning your very question ASUS A8M2N-LA CPU compatibility list. Now this is the only information I have been able to find concerning a processor upgrade for your Compaq Presario Media Center SR2013WM Desktop PC.

CPU upgrade on Satellite L30-101

Hi, I have a Toshiba Satellite L30-101. I've upgraded the RAM successfully to 2GB (2x 1GB) but I'm finding it incredibly hard to get information on processor replacements.
The laptop has the latest BIOS on it (3.10-WIN - 19/02/08) but when trying to find information regarding whats in it I'm hitting brick walls. Firstly the site > http://www.toshiba-tro.de/biosinfo/ < doesn't have my laptop on it,
Product Type: Notebook
Family: Satellite
Product Series: Satellite L Series
Model: ? unknown
Short Model No: ? unknown
I did hope I could stick an Intel Duo in but with the ATI chipset, I'm pretty sure it wont work but again without knowing whats within BIOS, compatible.. I'm lost. The only processor I can find which may work, same package, FSB, socket is an Intel Core Solo Processor T1350 which kicks out 1.86 GHz, not a massive difference and I'm sure it can't be the only replacement option.
Could someone and staff please help me with getting hold of BIOS info and compatible processors for my laptop. The current Intel Celeron M Processor 410 kicking out 1.46 GHz isn't good enough for Vista (cert on laptop) and basic multi tasking. Its lagging way too much even after a good tune up, ram upgrade, HD upgrade to 7200RPM. I'm in need of a processor upgrade but as mention finding it incredibly hard to obtain information of which would be compatible.
Sincerely,
Gourcuff

Hello
In my opinion your attempt to replace CPU is wrong. Why? Satellite L30 is not designed to offer some fabulous performance and it is designed for everyday usage. Best evidence for this was the price. It was not so expensive.
Can you please tell us why do you want to have new CPU? Do you use some special software?
Back to CPU replacement. As you probably know mobile computers have limited upgrade options and it is related to RAM and HDD upgrade. It is definitely unprovided for CPU upgrade and it is not supported. Specific design, especially cooling system is designed for certain CPU.
Due to all this you will not be able to find any relevant info about CPU replacement.
Check please this Toshiba document - http://aps2.toshiba-tro.de/kb0/TSB9401AX0001R01.htm

Is CPU upgrade on Satellite 2410-303 possible?

My Satellite 2410-303 has Pentium 4 Mobile 1.7GHZ processor. I want to upgrade its processor to Pentium 4 Mobile 2.8GHZ. I think that it is possible because its upper models have faster processor and that is unique difference between them.
Please, help me for this question and tell me is it possible?

Hello
You will be very lucky if someone has so good experiences with CPU upgrade on Satellite 2410 but on this forum you can find very nice comments about that. I have founded just two of them but very interesting. Check it out!

I can't set up iCloud drive on my iMac after upgrading to Yosemite

I can't set up iCloud drive on my iMac after upgrading to Yosemite - iPhone and iPad are updated but both say my iMac isn't (even though it is running Yosemite).
My iMac is OS X Yosemite 10.10 (14A389), memory is 4 GB 1333 MHz DDR3 and storage capacity is 273.64 free of 999.35 GB.
When i go to System Preferences and click on iCloud. The iCloud Drive section is greyed out and says setting up and a spinning pin wheel. It stays like this the whole time. I have tried restarting the computer. i amanita sure what else to do to make it work. Any suggestion would be great.

I found another way to correct this...
1) Select Message, then go to Preferences,
2) a window will appear with 3 options, General, Accounts, Audio Video, don't be surprised when you see a video of yourself, your camera just turned on.
3) Select Accounts (you may have several here)
4) Select the account that has "iMessage" under the account name. This may likely be your Apple ID ****@me.com
5) Look at what is checked under the "You can be reached for messages at:"
6) Select the one account (or more if you like) and deselect the others
7) Close the window and the problem goes away.
I'm not longer getting my sons iMessages.

How do I turn off messages on my iMac after upgrading to Yosemite?

How do I turn off messages on my iMac after upgrading to Yosemite?

Hi,
Open the Messages app.
Go to the Preferences item in the app's Menu.
Select the account pane in the Preferences.
Each active account should have a tick in the Enable this Account box.
This can be unticked.
This will stop accounts logging in but will not stop the app Launching in certain circumstances.
First of all check the app is Quit before shutting down the computer.
The fact the app is open even if all windows are hidden can cause the app to restart when you Start up the computer.
Messages is a Multiple window app and using the red button on the top left of a window only closes that window and does not Quit the app.
Also check the System Preferences > Users and Groups > your account > Login Items tab.
This will list items that are set to Start up when the computer does.
I have a couple of External Drive on other computers, some Anti Virus software and the common iTunes Helper plus an old version of TextExpander that will work if I launch the Preference Pane this way.

iWeb 'disappeared' from my iMac after upgrading to OS X10.8 - any ideas? tkx

Did you do an erase and install of Mt Lion? In any case you'll have to reinstall iWeb from its original source. Did iWeb come with your computer? If so you should have a couple of disks that came with your Mac and one of them will have the Bundled Software Install package on it. Like one of these:
Be sure to update iWeb to the latest and last version, 3.0.4, from Apple Downloads web page.

Satellite M40x will not boot up after CPU upgrade test

I have an M40x Laptop. I took the CPU out of it to replace it with another to test the computer booted up fine so I shut down and took it out and put it's original CPU back in, and it would not boot. Now it will not boot up at all with either of the CPU's all. When I turn on the power all I get is a white screen for a few seconds and the laptop shuts itself back down. Both the CPU's are good because I have since tested them in other computers to make sure that was not the problem.
Anyone have any ideas on what is causing this??

Im not surprised.
As far as I know Toshiba does not support any CPU upgrades and it's not advisable to do something like that.
Its a fact that the CPU replacement on the notebooks is not easy and mostly not recommended.
The processors used in portables are connected to the system board using a process called TCP (Tape Carrier Package). This is a permanent connection method and is used in the interests of miniaturization and heat dissipation.
Did you assign the new heat paste? Its necessary and important if you want to connect the CPU again.
So possibly this is a reason for the no booting.
I think more details you will get from the service guys in your country

1.0/1.1 GHz G3 Powerlogix CPU Upgrades in Beige G3

There have been very few postings of upgrades to the Powerlogix 1.0 and 1.1 GHz G3 CPU upgrades over at xlr8yourmac. Any of the upgraders here have any experience w/ this CPU upgrade in a Beige G3? Comments positive or negative? Problems?
I'm currently running a 466 MHz CPU in a Beige MT and am looking for a little more quickness. I've already maxed out the RAM and am running a ATA-133 Maxtor HDD on a ATA-133 SIIG PCI card.

Thanks for your comments. There are very few xlr8yourmac postings for the newer Powerlogix G3 upgrades in a Beige G3, but several for the B&W G3s. Likewise, xlr8yourmac's own CPU upgrade comparison using the new Powerlogix G3 upgrade was done w/ a B&W. The problem is that the B&W's were so different from the Beige, so quirky, and in fact so different from the front to the back of their production cycle that I wouldn't rely on their results as typical for the G3 upgrades. That said, most of the B&W upgrades w/ the Powerlogix 1/1.1 GHz IBM chip were favorable.
I ruled out the G4 upgrades for my Beige based on the long string of horror stories of those early adopters of G4 upgrades for their Beige G3s. They may have solved those problems, but I decided some time back, based on various web discussion threads, that G4s and the Beige just don't live and play well together.
It is true that the 66 MHz buss is starting to be a noticeable choke point. But, for the most part, speeding up what you can speed up, compensates for that problem. No, it can't make it into a new machine, but a used Mac at 933 MHz on ebay is going for almost $1K, and I can approach that performance for a lot less additional investment.

HP8000 elite SFF; what CPU upgrades are available

I've just bought an HP 8000 Elite SFF desktop (WB717ET#ABU) with a Pentium DualCore E5400 CPU running at 2.7GHz.
I was wondering what CPUs the Motherboard (Rev 0C by the looks of it) could accept in order to squeeze more performance out of it (and how simple such a CPU upgrade would be)?
This question was solved.
View Solution.

This image is from the maintenence manual for the HP 8000 Elite
Upgrading to a Core 2 Quad Processor or a Core 2 Duo would be a great improvement in power.

currently my ram is 4gb, which i can only use 3 of hence the upgrade to the 64 bit os soon
i will be upgradeing to 8gb ram,
just wondering what are my cpu upgrade options? would rather get the most out of this laptop, cant afford to buy a new one, willing to put about €100 into this

Hi:
I am not an expert on AMD processors.
If you think the ZM isn't a whole lot better (you need to look at the specs more than just the speed), then I wouldn't do it.
The speed isn't a whole lot different and the L2 cache is the same.
Normally the faster processors will run hotter when all else is equal (voltage, etc).
Upgrading the memory is the cheapest, easiest route to a better performing PC.
And definitely keep the vents and fan clean of lint and dust as much as possible.

CPU upgrades for a G4

I just bought a PowerMac G4 from eBay. I'm new to Macs and so far I haven't found much info on this model. It is an M5183, 733MHz, 512MB. I would like to upgrade the CPU. What are my options? What should I look for on eBay?

Also review the user report database on this site:
http://forums.xlr8yourmac.com/cpureview.lasso
You select your Mac model and the brand of CPU upgrade you are considering and get a number of user reports on how the install went and how it works.
NOTE: When you select your Mac model, you probably should choose "Apple G4 AGP Slot" unless you know you have a dual processor model.
You might want to ask in the Apple forum for for older G4 desktops (yours is older than the late FW800s and MDDs covered in this area) to see if someone else has already performed such an upgrade on a machine like yours:
http://discussions.apple.com/category.jspa?categoryID=113
I'm a little confused about which model you really have at this point. The M5183 number returns a Powermac G4 (AGP graphics) that had a 400, 450, or 500 nHz processor. I wonder if yours was already upgraded once (doesn't affect future upgrades).
Look for extra stickers on the back and see if any have "M" numbers that end with capital L's, a slash (/) followed by another letter (example: M7825LL/A, M7825LL/B). Those may help narrow the search.
A good resource for Apple Specs and how they were configured is the MacTracker database. Its format is more consistent than Apples' specs sheet format, making it easier to cmpare models. It's free and it's here:
http://www.mactracker.ca/
You can also run System Profiler (do "About this Mac" and click "More Info.." in the resulting window. On the first screen is "Hardware Overview." Copy/paste that (without the serial number) into a post here and that should precisely nail down your model.
