Upgrade my speed processor from 2.16 to 2.8 GHz

Can I do this ?

Indeed. The processors use the same socket so in theory you pull out one and insert the other. However I've seen no reports of this actually been done in an iMac yet I intend to allow someone else to pioneer the upgrade!
It's been done: 1.66GHz to 2.16GHz on a Mac Mini:

Upgrading L3000 N500 processor from PentiumDC to Core 2 or higher

hello,
Is it possible to upgrade or change the processor from Pentium Dual core to Core 2 or any with even faster processing speed?
I have a L3000 N500 model of lenovo this time..
Thanks!

Fortunately IBM / Levovo are particularly helpful sharing info and you will be able to find the exploded views and assembly / dissassembly instructions on the support sites. Some of the more basic core-2 chips are now very affordable, in the GBP20 range second hand, but there are many varients and you need to be sure of the socket (478 or 479), the power needs and BIOS support.
You may find more help at Notebook Forums (http://www.notebookforums.com/forum144.html).
As said it's a pretty tricky job and it might be easier to address other areas. I've found the combination of Windows 7, Scorpio hard disk and 4GB DDR2 RAM gives very acceptble general performance on a Celeron M430 based 3000 C200. Obviously it depends what you're doing!

Macbook air: should i upgrade Ram or Processor?

Looking at getting a macbook air 13 inch 256gb ssd. I am able to upgrade either the processor from an I5 to an I7 or the Ram from 4gb to 8gb. I dont know which one to upgrade. I can only do one. This will be used for school, music, and games like Simcity. What do you think?

lol, Im gonna go against what John said, and recommend you to go with the processor upgrade.
RAM is something you will ONLY notice when it fills up, and most applications on a Mac, including most most games, do not ever use more than 4GB RAM, and since the new Macs will have 1600mhz ram you will get a higher memory bandwith as well, making the size of the RAM even less important.
For most people the only time they will notice the difference between 4 and 8 gb ram is during video editing.
on the other hand, the 2.0ghz i7 will be approximately 27% faster than the i5, you also get 1 more mb of l3 cache. You will notice this much mor often than you will notice the RAM upgrade.
but, that's just me.

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Just upgraded an iMac with 4GB Memory and Intel Processor from 10.6.8 to Mavericks and Quicktime plays m4v files with stuttering audio

I just upgraded an iMac with 4GB Memory and 3.33 Ghz Intel Core Duo Processor from 10.6.8 to Mavericks. I now have Quicktime 10.3 which plays m4v files with stuttering audio. This is a nightmare as I use Quicktime a lot in my research. I have seen similar threads but so far only reporting the problem. For now I have installed Quicktime Player 10.7 (which appears in utilities, leaving Quicktime 10.3 in the main applications list) which plays the same videos with no problem, but it would be good to know if anyone has managed to find a workaround at all, or know if Apple have plans to do anything about it?

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.

Upgrade processor from dualcore to quadcore

Hi all,
it is possible to change processor from dualcore to quadcore wihout a change on my installation/configuration?
It is possible to shutdown, change CPU and restart my server?
Has anyone done this before?

It is possible to shutdown, change CPU and restart my server? Yes. However, it is wise to do (and test) a backup before doing any hardware change.
Has anyone done this before?Yes. No issues. It's a good idea to review the initialization parameters before and after.

System crashing randomly after upgrading processor from Phenom 9600BE to 9950BE

Few days ago I updated my processor from Phenom 9600 BE to 9950 BE. See all details about my system in my sig. Now the system is crashing randomly. I can quite figure out any pattern to it, but I think it may be due to temp. The 9600 was working quite steady at about 35C. The 9950 obviously will run at a higher temp. and it seems like it's running fine when I have my AC on in the room, which makes the processor temp on average about 45C. With the AC off, the room temp and humidity goes up but the processor temp doesn't exceed more than low 50ies C. Which should still be fine for that processor. So is it the board that doesn't handle the load of this processor? Or am I missing something else? The TLB fix in my BIOS is off, since it doesn't apply to this processor.
Thanks.

AMD uses JEDEC timings, not the dull EPP timings, those fail a lot (read about all the time) on AMD systems.
ok, so I read some info on the JEDEC and EPP timings... and now I'm even more confused. So if the processor is not using EPP but JEDEC, then that's why the AUTO settings in BIOS set my timings to 5-5-5-12 right? That makes sense. In that case, it could be running at 1.8V - according to the SPD tab table, right?
BUT:
Is the JEDEC#3 comparable in performance to the EPP? Or is the processor using the JEDEC settings just so it's safe? In which case, I should be able to safely run it at 4-4-4-12 at 2.20V since this is manufacturer recommended default? Or is the manufacturer recommended default referring only to EPP, and for JEDEC it should be used as listed in the SPD tab table?
And if i now decide to overclock the memory to 1066MHz (which I heard is possible), should I leave the settings at Auto or manually set them to 5-5-5-... something?

I have an iMac purchased new about 5 years ago with OS 10.4.11. I would like to upgrade to Lion. I currently have a 2.33 GHz Intel Core 2 Duo processor with 2 GB of ram. Can I upgrade to Lion, and what is the best way to do so?

From what I read here:
http://www.tuaw.com/2011/06/06/lion-...u-2-gb-of-ram/
s long as they already have Snow Leopard 10.6.8 installed in it.All a person needs to do with that type of iMac is to upgrade/max out their Ram. They claim that an Interl iMac with Core 2 Duo is all that is needed, as long as it has OS 10.6.8 installed. They say you don`t need the "Core i3, Core i5, Core i7, or Xeon processor"
But I wonder about the RAM speed, the iMac 2.33Ghz uses DDR2 SDRAM, which I believe is rated at 667Mhz. Lion maybe installed but it might be problems running smoothly or not?
Did some quick checking and the iMacs apple is selling this year use 1333MHz DDR3 SDRAM.
The only thing to do is to make sure you have a good back-up, Install your RAM and install Snow Leo, then wait a couple of hours and install Lion.
Good Luck

Upgrading AGP Graphics Processor; Dual vs. Single

So i just received a pair of old G4 towers. They're both AGP Graphics 400mhz machines, and i'm thinking of upgrading the processors on both. From what i understand from reading through the forums, they can take an OEM processor from some of the newer G4 towers. I've checked, and both machines have Uni-North numbers greater than 7 (one is 7, the other is 8), so they both can accept dual processors. Trying to weigh my options and decide what's best, taking into consideration that the bus on the AGP machine is only 100mhz compared to 133/167mhz bus on the faster processors...
1. Single 1ghz/933mhz/867mhz processor (will run underclocked)
2. Dual 500mhz processor (will run true @ 1ghz due to the 100mhz bus on the AGP machine)
2. Dual 1ghz/800mhz Processor (will run underclocked)
Thoughts? This would no doubt be a cheap upgrade, there are plenty of processors on eBay for under $100, and that makes it worthwhile for me.
Thanks in advance!

1. Single 1ghz/933mhz/867mhz processor (will run underclocked)
This will also require a 12v power modification to use a QS processor in a sawtooth.
2. Dual 500mhz processor (will run true @ 1ghz due to the 100mhz bus on the AGP machine)
This will run a true +500 MHz+, not 1 GHz. The dual processor just increases multi-thread processing ability. They do not double the clock speed.
But, this is a plug and play upgrade, and a nice improvement over a single 400 MHz processor.
2. Dual 1ghz/800mhz Processor (will run underclocked)
Again, there are voltage differences in the machine's which must be overcome.
You can find information on the actual modifications needed Here.
If you are capable of doing the mod work, I think it would be a fun project, and provide a boost to the old machines.

Is it possible to switch my processor from one laptop to another

i have 2 laptops, both are toshiba's, my old laptop runs better than the one i got for christmas becuase of the processor, my new laptop runs slow becuase the processor is a single core with 1 GHz my old one is dual-core 2.00 GHz, i want to switch them, they are both AMD so i am wondering if it would be possible to switch them
Here are the processors specs:
Old one:
AMD Athlon(tm) X2 Dual-Core QL-62 2.00 GHz
New one:
AMD C-50 Processor 1.00 GHz
so please, is it possible to switch them, and how would i go about switching them if possible.
thanks,

It sounds like a good idea, but it is a total non-starter. Sure, both CPUs are from AMD, but they have different packaging, different voltages, different Level 2 cashe, different thermal outputs and the connectors are different too. All of the circuitry around the 1 Ghz CPU was designed to handle that speed of CPU. If it could be done, you'd overclock the existing circuitry and burn out the system board.
Unlike a desktop computer that you can put in a new system board, CPU and video board, a laptop is pretty limited on what can be done as an upgrade. Your best option would be to find a computer that has the CPU that you'd want and buy it.

Hi, I am interested in upgrading to snow leopard but I've heard in some cases it messed up peoples computers. Is there any advantages in upgrading to Snow Leopard from Leopard? Thank you in advance for the advice points will be given to multiple users. Here are my computer specs (Leopard 10.5.8.)
Model Name:    iMac
Model Identifier:    iMac7,1
Processor Name:    Intel Core 2 Duo
Processor Speed:    2 GHz
Number Of Processors:    1
Total Number Of Cores:    2
L2 Cache:    4 MB
Memory:    2 GB
Bus Speed:    800 MHz

You need not upgrade unless there is something you do that cannot be done unless you upgrade. Upgrading OS X doesn't mess up anyone's computer. Users mess up their computers.
Your model has 2 GBs of RAM which is adequate for Snow Leopard although 4 GBs would be better. Upgrading to Snow Leopard will cost $29.00. You can order from Apple's Online Store. Here's a good procedure to follow:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

Swap Processor from G4 Quicksilver 80Mhz to G4 Digital Audio 466Mhz

If I swap the processor from quicksilver 800mhz and put it in my digital audio 466 mhz G4 will it work?
g4 Mac OS X (10.4.5)

Hi
it is actually possible, although whether it's worth the effort I'm not sure.
The CPU upgrades database at www.xlr8yourmac.com contains a number of reports from people who have installed a Quicksilver processor in a Digital Audio (select Apple AGP Slot for the Mac Model and Apple for the card manufacturer).
Both have a 133MHz system bus so the processor will run at the same speed (800MHz) without having to fiddle with the resistors that control the bus multiplier ratio.
The main issue though is the Quicksilver processor card requires a 12 volt feed to one of the screws that secure it to the logic board, although this can be taken from a spare hard drive molex power connector.
There are also possible heat issues, as the Quicksilver has a small fan between the processor heat sink and back of the case, where as I don't think the 466MHz Digital Audio has a processor fan at all.
I hope this helps.

Upgrading Dual 450 Processor

Good day all!
I would like to upgrade the dual 450 processor in my G4(Gigabit Ethernet) to at least a dual 1gig. I know the MDD's don't/can't work, but what about other used apple processors (ie. quicksilver or the like)?
I would like to keep the parts apple and although they are more rare than the MDD's they still pop up now and again.
Are there any issues/limitations?
Many Thanks,
El Jefe de Biosmell

Hi
The CPU upgrades database at www.xlr8yourmac.com is a useful place to look for information on processor upgrades. If you select Apple for the card manufacturer, you'll see reports from people who have used processor daughter cards pulled from other Macs.
Like you say, processor cards pulled from a MDD or FW800 won't work due to architectural differences such as the use of DDR RAM.
I believe it's technically possible to use a processor card pulled from a QuickSilver or Digital Audio, although it involves a lot of effort.
Firstly the bus multiplier on the processor card must be increased to take into account the difference in bus speed, which involves adding and/or removing resistors. For example, a 1GHz processor from a Quicksilver will have the bus multiplier set to 7.5 (7.5 x 133.33MHz = 1GHz). In a Gigabit Ethernet with a 100MHz bus the processor would run at 750MHz, unless the multipler is increased to 10.
Secondly Quicksilver processor cards require a 12 volt feed to one of the screws which secure it to the logic board, although this can be taken from a spare hard drive molex power connector.
Thirdly the Quicksilver processor cards and heat sinks are physically larger and in the Quicksilver are located in a different position on the logic board. When they're installed in a Gigabit Ethernet I think the card interferes with the ATA connector for the optical drive, and the heat sink may prevent the case from closing, unless both are modified.
Fourthly I have a feeling any level 3 cache may not be recognised, as the Gigabit Ethernets and Quicksilvers shipped with different G4 variants.
In short it may be easier just to use a third party upgrade. They're available from the following companies amongst others:

When is verizon going to upgrade fios speed tiers?

I'd like to upgrade my speed from 35/35 plan. Does anyone know when Verizon is going to upgrade the fios speed tiers? Compared to cable co docsis 3, fios is starting to look and feel slow.

Verizon does have higher speed tiers if you really want the additional speed. Their 50M/20M package is certainly feeling dated since it hasn't been updated in... 5 years? but they did introduce a 150M/75M package for a good deal of money a month, as fast but unfortunate as that might be. Now if what you're asking for is a speed boost on all the tiers, Verizon tends to boost the speeds every year to a year and a half. Lately these boosts have been silent. The 35Mbps tier, for example tends to clock in 43 or so Megabits on the download and about 38Mbps on the upload. Since you have that package, I'd check to see what you're really getting.
I would like to see 50Mbps/20Mbps go to 100Mbps/100Mbps sometime in the near future, though. 150Mbps/75Mbps goes to 250Mbps/250Mbps. That'd be very nice to see and by no means will DOCSIS 3.0 get that kind of upload any time soon.
As it currently stands, the highest DOCSIS 3.0 package available to me is 50Mbps/5Mbps. FiOS's basic package in my area still beats that plan in upload by an additional megabit. The legacy 50Mbps/20Mbps speed smokes that cable connection in upload, and is also $20 cheaper a month believe it or not.
Here, the packages run as follows:
1Mbps/384kbps DSL > Runs at 1Mbps/340kbps. Comparative Cable package: 768kbps/128kbps. ($25 for DSL and Cable).
3Mbps/1Mbps > Runs at 5Mbps/2Mbps. Comparative Cable Package: 10Mbps/1Mbps ($30/m FiOS, $40/m Cable).
15Mbps/5Mbps > Runs at 20Mbps/6Mbps. Comparative cable package: 15Mbps/2Mbps (~$50/m for Cable, $45 FiOS).
25Mbps/25Mbps > Runs at 30Mbps/26Mbps. Comparative Cable package: 30Mbps/5Mbps ($60/m for Cable, $55/m for FiOS).
35Mbps/35Mbps > Runs at 43Mbps/38Mbps, available if you have Phone or TV with FiOS. Comparative Cable package: 50Mbps/5Mbps (Same price as the 25Mbps for FiOS, Cable is $100/m).
50Mbps/20Mbps > Runs at 51Mbps/20Mbps. Comparative Cable package: 50Mbps/5Mbps. ($80/m FiOS, $100/m Cable)
150Mbps/35Mbps > Runs at 155Mbps/75+Mbps. Comparative Cable package: 50Mbps/5Mbps ($200/m FiOS, $100/m Cable).
So I guess it really depends on what market you live in, I guess. A Comcast or Cablevision market i'm sure would have higher speed Cable packages, and in the case of Cablevision, ones that cost less and that would be where I'd expect Verizon to boost speeds. Other than that, FiOS does have the overall edge in my area regardless, as long as you don't cheap out and go with the unadvertised packages.

The first to bring me 1Gbps Fiber for $30/m wins!
