Dual 2.3 G5 (not Dualcore). Bought ram, works, but is it safe?

Got a deal on this mac, it came with two 256m chips, I put two 512m in there, then bought 2 more 256 to make it an even 2gig of ram.
My question is, in System Profiler, the original ram, and the 512 sticks say speed: PC3200U-30330, but the two "new" 256ers I put in say PC3200U-25330
All memory says DDR SDRAM, and OK status.
The 256ers came from a dual G5 as well, non dual-core, so I assumed it's the same.
Is this 25330 versus 30330 thing something I need to be worried about?

It didn't for me. I just waited for the page to load, and scrolled to the bottom! I'm not subscribed to that service. However, it shouldn't damage the computer, it just might not function as well as if all the RAM had the same coding (probably only a small difference in performance if that): if they're different, what tends to happen is that all the RAM runs as slow as the slowest module.

  • After Effects CC on a Macbook. In RAM Preview the green progress line is not displaying. Preview works but no line to indicate progress. Is there a way to tunr the line back on?

    We have two Macbook Pros running CC After Effects. Bothdo not show the green line while running RAM Preview. The Preview works but there's no way to watch its progress. Any thoughts?

    It is an option in the timeline window. Upper Right Corner...
    Sometimes it causes problems. Maybe that is why it is turned off.

  • Suspend to RAM works but awakes immediately (pm-suspend)

    Hello,
    After after years of being unable to make suspend to RAM works on my lenovo Y530, I have finally found people who can do it. The trick is simply to add a new rule in /etc/pm/sleep.d/. I will edit the arch wiki page concerning the Y530 if I get it to work, but right now my problem is that the laptop immediately awakes after what seems to be a fully working suspend to RAM. Here is the log of pm-suspend :

    As you can see, everything works fine, except the fact that the computer awakes 7 seconds after going to sleep... Of course I'm not touching it when it goes to sleep. I've also tried to disconnect everything I could (USB device and wifi).
    Is there anyone who have already seen this kind of thing?

    Just out of curiosity, are you wired in to a network? I've heard that data transfer over ethernet will trigger the wake-on-lan settings in the BIOS, which would wake it from sleep.

  • Memory Error. Could not complete your request because there is not enough memory (RAM). But I have 24GB of memory. What do I do?

    I get the subject error but what do I do but reload. Surely 24 GB is plenty of memory. I can only load 5 RAW files for editing. Otherwise the subject error.

    Hi ,

    As much RAM as you can fit in your computer

  • Suspend to RAM works, but unable to wake it up

    From a virtual console (excluding X problems) I do `systemctl suspend` or close laptop lid.
    Expected behaviour: laptop wakes up when I tap space button
    Actual behaviour: reinserting battery is only way to wake it up.
    Not even holding down power button yields a response. Here is log from boot:

    Laptop is a packard bell intel atom CPU Z520 1.33GHz with gfx card: Intel GMA 500 series, also known by it's codename Poulsbo.
    How can I debug this further?

    Opening lid do not wake it up. The only way to make laptop usable again is reinserting battery.

    I recently just dropped my iPhone 5c, the screen is blank and it will not turn on (pitch black until i press lock button then it turns a little blue). siri works if i hold down the button but the screen is still pitch black. the screen is also completely popped out. What should i do? what do you think apple will do?

    take it to Apple and have the screen replaced.

  • I can't search for apps in App Store why not? Genius still works but not search?

    Why can't I search for apps but can still use genius?

    I have same issue. It will let me know to update apps.
    But if I want to search an app my friend may have. Nothing comes up after typing it in the search bar.
    Same with the featured apps or the star charts , nothing comes up.
    Now I just updated my iPad and so far so good. But my iPhone 4S is the problem since upgrading to ios6.
    What to do.....
    Apple...... You shouldn't rush these things.... Take your time and make it right .....
    Any ideas .. Guess we just have to wait for apple to fix the issue...

  • Will logic pro x run on my mac mini dual core intel i5 with 4gb of ram and mountain lion ?

    hi there guys,
    will logic pro x run on my mac mini dual core intel i5 with 4gb of ram and mountain lion ?
    I'm not sure if my machine is 64 bit - it is the current model base mac mini.
    Many thanks for any help you can offer !
    Simon

    SkiJumptoes is right. 4GB is not enough to comfortably run Logic X.
    Your Mac Mini will need DDR3 SODIMM RAM. That website seems incredibly steep though. I guess that's the price of finding it for you. You're better off going to any below:

Please advice whether it would suffice a normal user who works in a management consulting industry with project presentation related software in work ? Thanks.

    Not only would it be safe but less expensive as well.  The tray loaders are deemed to be the most reliable.  Apple does not support Blueray so avoid that.

  • Bought ram for Macbook 4,1 and wont boot up

    Hey guys i just bought some new ram to upgrade my macbook 2.1 Ghz Intel Core 2 Duo running Snow Leopard 10.6.8 and it says its the right ram for it but it doesnt boot up. the RAM i bought is 2GB PC5300/667Mhz DDR2. i bought 2 modules to equal 4GB and it doesnt boot. i tried one stick, both sticks, one new and one old, still nothing. the disk drive runs but thats all. So either i got bad ram or they labled it wrong? What can i do besides return it?

    If you bought your RAM at a place that also sells PC RAM you may have gotten mislabelled RAM. PCs can handle different RAM speeds so they’ll often label higher speed RAM as a lower speed rather than make two different speeds of RAM. But Macs are much more picky. They require a RAM stick to be exactly 667mhz not 675mhz or 800mhz. The way to tell is to put one of your old RAM sticks in and it will force the new RAM to run at the correct speed.
      This is from one review of PNY RAM:
    "These modules are actually 800Mhz. PNY no longer makes or sells 667Mhz modules. Not all computers that require 667Mhz are compatible with 2 800Mhz modules. They refuse to down clock properly. This is especially true with a number of Core 2 Duo MacBooks. Spoke to PNY support, they flat out told me that yes, they sell 800Mhz modules in 667Mhz packaging. If you RMA a module that is 667Mhz (or supposed to be 667Mhz) they will replace it with an 800Mhz module as they no longer have any 667Mhz SODIMMs, not even for RMA replacement!"
    These are good online stores for Mac compatible RAM
    OWC 667Mhz RAM
    http://eshop.macsales.com/shop/memory/MacBook/DDR2/ - They offer Mac tested RAM at very good prices.
    Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
    Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.

  • Not enough memory (RAM) error. Can't open TIFF file.

    I can't open a 74MB TIFF file in CS5 photoshop.   I get error message: Could not complete your request because there is not enough memory (RAM). 
    I have 16GB of RAM and 55.5 GB of scratch disk.
    I am using my recently installed copy of Photoshop CS5 64bit on a virtual Windows7 machine running in Parallels on a recently bought MacBookPro. This software (now deactivated) has run successfully on an XP machine and has successfully open TIFF files of this sort before.
    I don't know whether this is relevant, but I can't update my copy of photoshop either. It downloads the updates, but will not install them.

    I have discovered that the problem is that the TIFF files I am tying to open are 32 bit files.  There are several references on the Internet to Photoshop not being able to open these files   These are output files produced by the astro-imaging software Deep Sky Stacker.  Within DSS  I can save the 32 bit TIFFs  as 16 bit files which photoshop CS5 can open fine.
    Does anyone know whether Photoshop CS5 can open 32 bit tiff files at all?  Would it help if I could update my version of Photoshop (see update problem above)?

    If your layers in Photoshop document are fairly complex, then working with them frequently can be little tough keeping in mind that you're using both Photoshop and your OS as 32-bit only. Photoshop will use some portion of the scratch disk as its virtual RAM when it is out of memory using its available memory that you have set for Photoshop in its preferences. The hard drive spaces left in your C drive may fall short depending on the page file size you've set for Windows becasue Photoshop expands an image to its actual resolution when it is opened in Photoshop/placed in Photoshop layer, thus taking up a lot of memory depending on the size and resolution of the image.
    Make sure no other programs are running in the background along with Photoshop. If you're working with a dual monitor, try disconnecting one of the monitors and see if that resolves the issue. Keep the history/ clipboard clean. Frequent saves will help in this matter.

  • Dual layer DVD will not play after iDVD burning

    Hi All,
    I am having some trouble making a useable DVD. I have a video that I recorded and imported into iMovie (2h33m long). I exported it to iDVD, which told me that I needed to use a dual layer DVD to make it fit. Here's where I noticed the first problem: iDVD has one option for a dual layer disc, stating that it has 7.7GB storage space, and my discs have 8.5GB. I set it to use the standard setting for the DL disc any ways, turned the quality down a bit to make it fit, and burned the DVD. After burning two discs, I still do not have one that works. It comes up as "supported disc not available" on my Mac, and as a blank disc on any other machine I put it in. It will run on my coworker's brand new iMac, but that is the only one. Am I doing something wrong? The only mistake that I have corrected since I have tried all this is changing the aspect ratio back from 4:3 to 16:9 in iMovie (I am not sure how that happened, as the video was originally recorded in 16:9). I am re-exporting the file to my desktop now in the proper ratio, and changed the quality to HD. I am waiting for the file to encode as we speak. Any help would be greatly appreciated, as this work is for my local school board and is very time sensitive.
    I am running a 28" iMac, 2.66GHz Intel i5, 8GB RAM, 1TB hard drive on OSX 10.6.8.

    I set it to use the standard setting for the DL disc any ways, turned the quality down a bit to make it fit, and burned the DVD.
    That part I don't understand.
    iDVD encoding settings:
    http://support.apple.com/kb/HT1502?viewlocale=en_US
    Short version:
    Best Performance is for videos of up to 60 minutes
    Best Quality is for videos of up to 120 minutes
    Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
    That was for single-layer DVDs. Double these numbers for dual-layer DVDs.
    Professional Quality: The Professional Quality option uses advanced two-pass technology to encode your video (The first pass determines which parts of the movie can be given greater compresson without quality loss and which parts can’t.  The second pass then encodes those different parts accordingly) , resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.
    In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
    You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
    Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
    NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
    And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

  • Audio layer causes "NOT realtime" on RAM Preview

    Hi I am using a new machine I built mostly for AE and music video production.
    Mac Pro 2008 - 2.8ghz 8-core
    8GB RAM
    AE CS3 + Nucleo Pro 2.0
    Areca 1261ML
    I have spent some time tuning the Nucleo & AE parameters to work most effeciently and I'm happy with the performance execpt for this issue.
    What I am noticing is I get 29.97 fps playback with the RAM preview and NO audio, but as soon as I check the audio layer my fps drops to 22 fps and the audio only plays for only half of the preview. Most importantly the audio gets out of sync... It is frustratingly difficult to align video and audio like I've grown use to in AE7 & 6.5
    Perhaps I'm missing a preference somewhere?
    My comp is 29.97 fps 640x480. My project settings are set to 44.100 khz.
    My footage is partially
    60fps 640x480, 48K audio (audio unchecked)
    30fps HD 720p , 48K audio (audio unchecked)
    & mostly stop-motion jpg sequences taken from a 2MP camera.
    1 song - 44.1khz wav
    All my previous projects behave similarly.
    All of this plays fine with no audio. However, even 29.97 SD alone still causes "NOT realtime" playback as soon as I check the audio on. This happens no matter if it is full-res or 1/4.
    I have tried:
    making sure all audio is set to 44.100Khz and also tried 48,000khz (with 48k audio)
    changing the buffer size on the audio preference
    swapping out the 44.100 wav with 44.100 mp3 or a 48,000 wav
    Also tried switching to an external USB audio device in the audio hardware preferences - no change
    still plays back in the 22fps range...
    I don't remember having this issue on my XP64 quad core machine w/AE 7.0 OR with my old dual cpu XP box running AE 6.5.
    As this Mac Pro is supposed to be for music video production. This is really an important issue to me and is making my work very difficult and tedious -- or I have to just render it out like in the ole slow computer days...
    *EDIT* It does play 15 fps realtime -- if I tell it to skip 1 frame (just double checked - thought it played sluggishly too) But this is kinda upsetting... It should resolve my timing issues for now.

    no effects on the audio -- it's just straight wav 44.100Khz.
    Preferences > Audio Hardware > Built in line output
    Preferences > Audio Output Mapping > Built in line output
    System Preferences > Sound > Output > Built in line output
    All of these settings in any configuration produce the exact same result. Presently set to "built in line output", I have also tried using the USB output and the ones labled "built in line input/built in line output" -- no success, even if all the settings are set to the same line or pointed to different audio hardware. Buffer size also has no effect.
    I'm really stumped.
    Also, my audio library is on a HDD by itself. I tried hard to set up the machine to not have issues like this...
    I'd like to get a MOTU Ultralight for audio recording one day, but I don't think this is a $500 issue now. Plus, I doubt it will make a difference.
    I mean 15fps works, but I miss stuff when I'm viewing stop-motion footage. I feel like I wasted a lot of money on hardware and CS3.
