Adding RAM - which slot has original 64?

When I bought my flower power imac 500 mhz I added ram. It was originally supposed to come with two 64 mg slots but I had 128 installed bringing it up to 192. Thought back then this was enough : ) . I want to add RAM but don't know which one is the 64 Mg one. Would it be the bottom or the top one. I tried to read the labels and it doesn't seem to say on it. One does have a blue stickey dot on it. I was thinking this is the larger one. It is on the top when you are looking inside the slot in the back. Anyone know if there is anyway to tell. Don't want to take the wrong one out.

Hello Kathy,
Go into System Profiler. Click on Memory. It will
show the two slots. On my 400MHz the two slots
are J13 and J14. J13 is the TOP slot. Hope this helps.

I just put 8 gb of memory into my new mini, but the computer is only reading 4gb. It tells me that bank 0 has 4 gb and that bank 1 is empty. Which slot is "o" and which slot is "1" ? I re-wiggled the new memory sticks, but it still only reads one of them.

I just added two new memory sticks to my new mac mini, each stick has 4 gb. The computer tells me that it now (with the new memory) only has 4 gb total, however. It says that bank "O" had 4 gb and bank "1" is empty. My two questions are... Which slot is bank o and which slot is bank 1? The computer didn't beep or anything, so I think its just that it doesn't recognize one card. I wiggled them again, in case maybe I didn't put them in tight or something, to no effect. Any suggestions on what I may not have done right???

Same issue here. All chips, old and new working in bottom slot 0 but nothing working in slot 1 (top.)
It also seems to be important to make the insertion at the right angle that was actually steeper than I thought at first. I also got a nice click when it slipped into place. You can also look at the position of the center slot/protrusion on the bottom chip to get an idea of how far the stick needs to be in.
Another thread pointed out that you have to make sure that the retaining clips don't engage before you get it into place as they prevent further movement.

Which slot do I take the ram out and put the new in?

I have a 24" iMac 2.33GHz with 2 gigs of ram. On my imac I can only put a total of 3 gigs. So Currently I have (2) 1GB modules each in both ram slots on my imac. So that means I have to remove pone of the 1GB chips and put in the new 2GB module I bought from crucial. So after shutting down the computer, unplugging everything, and setting it on a table, my question is:
WHICH 1GB ram do I remove? The left(looking at the front of the imac), or the right (looking at the front)?
I will be installing it in later tonight so ANY help is greatly appreciated.

It does not matter which module comes out, however I would suggest that you remove the frontmost module simply to make it easier to remember which module has been replaced.
Actually, you will have to take one more step before you replace your ram module.
Take the cover off before you replace the module. It will go a LOT smoother!
Just kidding. You pretty much have it down pat.
Seriously, just remember to ground yourself before touching the ram module and do NOT touch the contacts on the module.
Hope this helps

How do I get my photos off 1st generation itouch? I have macbook pro, ipad, iphone. Itouch syncs but does not have option to share in any capacity ie send via email, etc. Also, the computer from which photos were originally taken from has crashed.

It has always been very basic to always maintain a backup copy of your computer.
Did you fail to back up your pics?
The photo sync is one way - comptuer to ipod.
You can e-mail them to yourself (instructions in the manual), but they will not be of the original quality.

iOS 4.3.5 is not the same as iOS 5. iOS 5 with the new features you list has not been released.

How to find original document for which settlement has been carried out.

Hello Friends,
As a process of period end, we have executed the automatic settlement for assets under construction for an internal order through KO8G.
After completing the run system has posted a document successfully.
When I want to check the original document for posted document through FB03, through Environment  Document Environment  Original document. System is showing the same settlement document rather than the original document.
Can any one explain me how to check the original document for which settlement has been carried out.
Regards,
RS

"Original document" means from where the document originated. Means for eg MM invoice will be original document for FI invoice. Hoever for settlement document, Settlement process it self is the origin for posting. This way, You cannt trace back the Fi postings which got settled. You need to run line item report for the object and analyse the Fi postings and corresponding Settlement postings

Pavilion dv6-3130tx Blue Screen (BSOD) on adding RAM to second slot

Hi there,
I own a HP Pavilion dv6-3130tx with total of 3gb of RAM, one 1GB chip and one 2 GB chip. Recently I have been getting a lot of system crashes/freezes and occasional Blue Screen of Death (BSOD) with a variety of error messages. On contacting HP care in India they said to check the RAM chips and the slot for any problem. I have identified that the second slot is one creating the problem as the system crashes if use any one of the chips on that slot while both the RAMs work fine on the other slot.
Additionaly the RAM port/slot cannot be replaced as such, and since it is out of warranty getting the motherboard replaced isn't an alternative either.
So does anyone have any idea what might be the best way out of this problem?

Did the 3GB of RAM come with the computer or did you upgrade it at some point?
What version of Windows are you using?

Adding RAM to 1.6 GHz G5

I just finished a rather strange process of adding RAM to my G5 which I thought I would share, in case it helps others:
First of all, I have a 1.6 GHz CPU machine, which has 4 DIMM slots. According to the Setup Guide, since there are only 4 slots (not 8), you need to use 333 MHz, PC2700 DIMMs (not 400 MHz, PC3200 DIMMs).
When I first got my G5, it came with 256 MB of RAM (2 x 128 MB 333 MHz, PC2700). About a year ago, I added 512 MB (2 x 256 MB 333 MHz, PC2700), bringing the total up to 768 MB. This addition went smoothly, without any problems.
Recently, I decided to replace the original 256 MB of RAM, with two more 256 MB modules, bringing the total up to 1.5 GB, so I ordered "1 GB DDR400 PC3200 2x512 DIMMS" (Part # M9653G/A) directly from Apple. Note that the RAM Apple currently sells is 400 MHz, PC3200, not 333 MHz, PC2700. In fact, before placing the order online, I called Apple to ask about this, and the person I talked to assured me that this would not be a problem, and that my 1.6 GHz would work with the 400 MHz, PC3200, despite what the manual says, so I ordered them.
Upon receipt, I removed the original pieces, installed the new ones, and my G5 would not acknowledge their presence. It said I only had 512 MB. I called Apple to report the problem, and they suspected it was simply faulty RAM, so they sent replacements. When I got them, I installed them, and got the same results. I called Apple to tell them it still wasn't working, and they had no idea why. Once again, I pointed out that they were sending me 400 MHz, PC3200, not 333 MHz, PC2700, and they still insisted that this was not the problem, but I started to suspect even more that it was, especially after trying to upgrade twice.
In order to test this theory, I ordered RAM from MacMall. This time I ordered 1 GB, in the form of 2 x 512 MB, 333 MHz, PC2700 (made by Kingston, Manufacturer Part No. KTA-G5333/1G). When I received these, I moved the original replacement RAM up into the top two slots, where the original ones were, and placed the two new ones in the bottom two slots. When I tried to turn the computer back on, it wouldn't. The light on the front would flash once, then pause, then flash once again, then pause, etc. When I checked the manual's troubleshooting section, it described what two, three, four, and 5 or 6 flashes meant, but not one. URGH!
At this point, I had no idea what was wrong, so I took my G5 to my local Apple store to ask them. The guy there had the idea of putting one of the original replacement RAM in one of the two top slots, and one of the new replacement RAM in the other top slot. Then he put one of the original ones in one of the two bottom slots, and one of the new ones in the other bottom slot. Believe it or not, not only did the computer turn back on, but it also recognized the new total of 1.5 GB of RAM!!!
This was such a strange process that I thought I would share it, in case someone is also currently going through this process, or wants to in the future.
Hope this helps, and I also hope I've made it clear exactly what happened. If anything isn't clear, please let me know, and I'll try again.

PC3200 is fine for that system. The problem was that you were installing the RAM in the wrong slots.
The RAM must be installed in matched pairs, one in the top, one in the bottom, working out from the middlemost pair.
Viewed from the side
======== Slot J14
======== Slot J12
======== Slot J11
======== Slot J13
So, one pair of identical parts goes in J11/J12, and another pair goes in J13/J14. Doesn't matter if the bigger pair is first or second.
This wasn't in the manual for your Mac?

Some thoughts on adding ram to G4 sawtooth

I've gone down the list and read all I can about adding ram to my G4. It now has 2-64mb pc-100's, 1-256mb pc-100,and 1-128mb pc133-333. I would like to max it out since it's been freezing up during graphic work when I have more than one Adobe application running. Am I correct in thinking that's the problem or could there be something else going on? I have already expanded with a 1ghz processor, and 120gig hard drive. I'm running Panther. Any suggestions? Also I read somewhere that it matters what slot you put each ram chip in. Is there some order to this?

Claire, In the Finder under the Apple/About this Mac/More Info/Memory you will see the Memory Slot order of each stick follow by their size. Take a look here she is replacing memory in the first slot, also the size should be printed on the side each stick.

Added RAM and now Applications won't open

I just added RAM (8GB)to my computer and now my InDesign will not open.
I did the OptApple+PR reset.
Do I need to do something after upgrading RAM so things run smooth?

Will the computer start up normally? If not, is the led on the front blinking? If it does start up normally how much RAM does it think it has?
Have you tried going back to the original RAM?

When adding memory does slot matter

I just picked up a gig of RAM to add to the 512 MB that came with my powerbook. I was wondering if it made a difference as to which slot the 1GB or 512MB was in. Which configuration works best? Thanks for any help.

Adding RAM and making room/trying to upgrade Mac Mini

I have a 2007 Mac Mini on Tiger and wanted to upgrade to Snow Leopard but even taking the machine down to base with erase and install, it still says the RAM is not enough. Where and how can RAM be added?

your mini has 1GB of memory, with maximum 2GB. SL requires minimum 2GB ram.
If you decide to add ram, use good reputation supplier like Crucial or OWC. Be sure to buy compatible ram.
In OWC sites you find the way how to do it.

Which slot should i install my X-Fi

I'm about to change my motherboard soon to a Gigabyte GA-965P-DS3 rev 3.3. Which slot on that board doesn't share its IRQ with other devices, or in other words, which slot is the safest to install the soundcard in (to avoid potential resource conflicts)?
Would appreciate a quick reply. Thanks!

Put the card in the slot far away from graphic card. This is because of EMI disturbing your sound-output. In windows, if you PC supports APIC your chances are very good do not have any IRQ-Sharing. The BIOS- Message wont give you the needed info for IRQ sharing anymore. In windows there are 24! IRQ' s , your BIOS only has access to 6.

Does adding RAM help solve iMovie4 jerky playback

I have been reading threads about jerky playback in iMovie4 in large projects, after adding music from iTunes etc. My wife has a monster project and playback during editing has became very eratic. I have emptied cache, repaired the hard drive, repaired permissions etc. I have not tossed iMovie preferences. I have 23 gigs of space on the HD and a 250gig external FW HD that I bought after she started the project on the internal HD. I would like to know from you experts: 1. Would it help to move the project to the larger external HD? 2. Would adding RAM help (currently iMac G5 1.8mhz with 768 megs RAM)? 3. Is there any way to tell if the project will export to iDVD smoothly if it continues to look terrible in iMovie playback? I hate to go through a few hours of rendering for nothing. Thanks so much for your help. I always find good and useful info in discussions.

Michael, there are some very useful applications that I highly recommend to keep your Mac running smoothly. As a defragmenter I use Allsoft's Disk Warrior that also has a very good directory repair feature. Check out also Drive Genius that has a host of useful features. Also get iMovie file fixers, invaluable tool that is free that will allow iMovie to import certain files in audio and photo formats that are greyed out and also has other features. I believe I got mine from Mr. Lennart Thelander in previous posts here. Cache Out is an excellent application to clear out cache files. I also advise you do a regular permission repair from Disk Utility in your Utilities folder that is on your Mac. These are basically my must have applications. As for copying your iMovie project to your external, just drag your entire project folder ( the blue one with the media and star folder(s) in it directly in the external hard drive. I find that iMovie is one application that requires a clean (defragmented) drive with ample space to spare. I defrag my drives if I trash files often from them, or if I notice erratic and jerky performance or slowness in response. I hope that some of my suggestions will help your in your editing.

Maximum RAM which can be fitted?

I have a Powerbook G4 17 inch, serial number W8*******QRV which currently has 1Gb. of RAM fitted.
I have tried to fit 2 x 1Gb. of DDR1 333MHz. PC - 2700 (SODIMM) but have had no success.
The laptop does not give memory error beeps, but instead displays a request to power off and re-start in English, French, German and Japanese.
Is this machine somehow limited as to how much RAM it can accept, or is tyhere something else which is preventing a successful upgrade?
I know that it is an old machine, but it still functions very well for my purposes.
Any assistance would be gratefully received.
<Edited by Host>

The maximum RAM for that PowerBook model is 2GB; there appears to be a problem with one of the RAM modules installed.
