1GB 533MHz DDR2 SDRAM / Cost Versus Quality

Total Confusion.
Firstly
Newly(ish) arrived G5 17" iMAC / iSight 1.9GHz c/w 512MB RAM.
I want to upgrade the RAM and can't afford the 2GB Module so contemplating the 1GB as above. Prividing 1.5GB in total. Costs range from £140 (Apple) to unbranded ex eBuyer at £52.
All cogent comments welcome.
I have used generic ram in the past with my iMac 500MHz Power PC G3 with no trouble but a little wary as this has been my first 'pukkah' unit.
I understood the installed 512MB is / was a fixture. Having read commenst on this forum note possibilities of installing 2 off 1GB modules.
Possible? Yes/No Perhaps?

As far as I understand it, the iSight G5 iMac only has one memory slot that is "user accessible", while on the Intel version both memory slots are. The "first" 512 MB RAM are soldered onto the motherboard and thus can't be swapped.
As for memory I bought a gigabyte of TwinMOS branded for my Intel Mac. It was the cheapest I could find around here (Sweden) and is working just like it should. (Okay, so it's been less than a week since I got the computer, but I figure shipping and installation are the most dangerous moments so if it works now it should work for quite a while. Time will tell ...)

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.
I use wireless to connect to the Internet and everything works fine when I sign on. After being on line for awhile and my remaining battery power at about 60%, I lose connectivity. I turn off Airport, restart it, and I am asked for my secure password. I enter the password but cannot reconnect. So, I shut down the computer for 5 to 10 minutes, restart, and everything works great again.
Has anyone experienced this behavior and do you have any suggestions as to what is causing the problem.
Thanks for any help you can give me.

I think I hit the wrong key ... so here it is again!
Thank you ... I keep seeing this i5 and i7 processor mentioned and it is also recommeded that I stream using it. Do you have any suggestions on which MacBook would serve me better? Or is there an upgrade of any kind that will help me?
Thanks again.

According to the Lion webpage, you would need to add more RAM to your computer and check to make sure you have about 7GB of free hard drive space.
The page can be found here if you need more info:

You do realise that you can add Ram, if that is all that is holding you back it's not a problem.
Tell me the exact model and age of your Mac. (The model identifier can be found by holding the option key down and clicking on the Apple Menu, select System Information (top entry) and then read the model identifier from the righthand panel (2nd entry down)

I am using an iMac7.1 with 1GB DDR2 SDRAM of speed 667 MHz on board memory. I would like to know what is my best option to upgrade to 4GB on board memory so that I can run Lion OS. Is there a speed limit of the DRAM I can use? Please recommend.

You can install 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs. The maximum amount of RAM is 6 GBs. Visit DataMem or OWC to get the proper RAM at reasonable prices.

Is it possible to install CS5 or CS5.5 on a 2.4 GHz Intel Core 2 Duo 4 GB 667 Mhz DDR2 SDRAM MacBook Pro running 10.6 (Snow Leopard)?

Hi Carolyn, thanks for your quick reply. First thing I did before posting my question was to check the system requirements for Creative Suite, both on Apple and Adobe's websites. But I am however confused about the difference between "Multicore Intel processor" vs "Core 2 Duo", and keep hearing stories about CS5 not working properly.

Hi LMDV,
Welcome to the community!
Multicore Intel processor also known as Dual core processor is required to run the CS5 or CS5.5, you have Core 2 Duo which is better then Dual core and sufficient to run the CS5 and CS5.5 apps. You just need to check other system requirements which is mentioned here:

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Get an external hard drive on which to store some of your files after which you can
      erase the data from your internal drive to free up space.
5. Also see Freeing space on your Mac OS X startup disk.
6. See Where did my Disk Space go?.
7. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

I'm unable to burn DVDs on my MacBook Pro 2.16 GHz, 2GB 667 MHz DDR2 SDRAM

Hello all,
I'm unable to burn DVDs on my MacBook Pro 2.16 GHz, 2GB 667 MHz DDR2 SDRAM running 10.4.8. When I go to burn a DVD I get one of two codes 0X8002006D, 0X80020022, why is that a 3,000 CPU cant burn a DVD. My Mac is total up to date with all software and firmware. I saw in the Discussions that I'm not the first person to have this issue but I don't see an answer from Apple, I'm pretty sure it not the DVDs (Memorex DVD-R 16X) because my ****** pc can burn them and it was a 100 pack that I used about 50 from it that I burn on both Macs and the ****** PC. I also have a Dual 2 GHz PowerPC G5 with 2.5 GB DDR SDRAM running 10.4.8 which is also unable to burn them and it also comes up with the same errors. I have not had this issue until I updated my Macs to 10.4.8, PLEASE HELP.
Thanks,
Coons

Yes I can play CDs and DVDs but I was not able to burn a 4.01GB folder, I have since decreased the folder size to 3.75 and was able to burn the DVD. I'm creating another just to double check, my G5 was unable to complete the task and I also gave a shot at a 2.77GB folder and it failed I also gave a 200Mb file a chance but it still did not burn. I was able to burn the same 200MB file on a CD, PLEASE I NEED HELP.

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation may solve a problem that isn't solved by reinstalling in place.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications of the machine.
Apple Diagnostics or the Apple Hardware Test, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test, if applicable.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Connecting more than one display is another reported trigger for OS X bugs.
If your system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
Otherwise, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.

Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say. It will shut down if it gets too hot, but that's not a normal occurrence. I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
First thing I would try to do is reset the SMC. If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
If a fresh system doesn't help, you'll need to get it checked out by Apple.
Edit: Oh, and sig is absolutely right... please don't post in all caps! It's very irritating.

I have an early 2008 macbook pro that is running slow after upgrading to lion. Is there anything I can do? this is what I have,Processor 2.4 GHz Intel Core 2 Duo, Memory 2 GB 667 MHz DDR2 SDRAM.

First, back up all data immediately, as your boot drive may be failing.
Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. What approximate values are shown for Reads in/sec and Writes out/sec?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

Leopard requirements/10.5.x...
    * Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
minimum system requirements
    * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
    * DVD drive for installation
    * 9GB of available disk space (I say 30GB at least)
Classic/OS9 Apps no longer supported.
Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...

I have a mac OS x version 10.4.11 2 GHz Intel Core 2 Duo 1 GB 667 MHz DDR2 SDRAm. Can I use Crucial 2 x 1 GB 667 MHz DDR2 SDRAN to upgrade memory?

The downloads are probably .dmg files (disk images). You would open the disk image (double-click it) to find the application or an installer. If it's the application itself, you then drag the application to your Applications folder to "install" it. If it's an installer, double-click the installer to run the installer that installs the application.
NOTE: If you iMac is Intel, it's not a PPC G5.
