Possible RAM Solution -Upper/Lower RAM not being recognized for Al 1.25

I was poking around on my 1.25Ghz Al pb (seemed sluggish) with 1.25 GB RAM, when I noticed that only 1 GB was being recognized. I had a 256 MB chip in the lower slot and a 1 GB in the upper. I accessed the RAM bay and reseated both chips. Upon rebooting, 1GB was still only being recognized (I was very, very thourough on the reseating, spent 5-10 minutes on it) Panic was starting to set in, whether the 256 went south (best possible outcome) or the lower slot was borked. I decided to test the lower slot and swap the RAM positions. I reseated with the exact same care, and prepped a reboot. Upon rebooting, all was restored. 1.25 GB was recognized, and all was well with the the universe. Any ideas as to what had happened? When I swapped the RAM chips, did it get reassociated with the OS? Had the 256MB chip lost it's relationship with the logic board?
(sorry, I posted this in the wrong forum earier, mods please delete prior post)

Hey, whatever mod deleted the reply to this and my subsequent reply to that, why don't you tell me an accurate response? Tell me exactly how working RAM could break the RAM slot it wasn't even plugged into.
Otherwise, Apple is telling a bunch of bull and refusing to admit to a product flaw. Why delete a post speculating on such an issue? All it does is lend credence to the speculation. I believe that it is the case all the more now that you have deleted the posts.

G4 RAM Not being recognized

I'm trying to install 512 MB sticks of RAM into a G4. It seems to recognize the memory sticks inconsistently. I had three sticks, it only recognized two. I switched the slots then it read one stick but not another. Does anyone have any troubleshooting tips?
Same thing is happening with a G5 except with larger capacity memory sticks.

I have just had similar problems... with help from these boards I managed to fix it.. I think the PRAM reset is the best place to start trouble shooting... restart your machine holding down the Apple+ Alt + P and R keys until you hear three chimes.. then let go of the keys... this cured my problem.
P.S. this will not work with a wireless keyboard, you need one that plugs into a USB port on the back of the Mac, dont use a USB hub, plug it directly into one of the USB ports on the back of the Mac.
Hope this helps

RAM not being recognized what it should.

I recently bought 4 x 4GB 800 MHZ modules, but only 2 are recognized as 4GB the other 2 shows as 2GB but all at 667MHZ when it should be 800MHZ, can any one tell me what the issue is?
Thanks

Send them back. If new RAM - by itself - does not work - the set should be returned.
If any one DIMM is 667 then they all will have to downclock
Komputerbay 8GB (2x 4GB) DDR2 PC2-6400F 800MHz ECC Fully Buffered FB-DIMM (240 PIN) 8 GB w/ Heatspreaders for Apple computers
http://www.amazon.com/Komputerbay-PC2-6400F-Buffered-Heatspreaders-computers/dp/ B005HIWDBE/
Not sure about that brand Komputerbay $89 2x4GB
Otherwise, 667Mhz is much cheaper and works just fine in a 2008 3,1 along with filling all 8 DIMM slots works to improve performance so much so that even the small 4% difference is not a factor and you come out ahead.
I use these: 8 x 2GB $92

You were sold a set and they are not what they were suppose to be and there is no quick fix other than to replace and have a correct set sent out.

RAM not being recognized?

I have a iMac G5 Built in iSight with a built in 512MB and I have just purchased a 512MB chip from the apple website, after instaling it and checking the "About this Mac" options I see the following under the Memory field.
"DIMM0/BUILT-IN Size:512 MB Type:Built-in Speed:Built-in Status:OK
DIMM1/J6700 Size:Empty Type:Empty Speed: Empty Status:Empty"
Is there something I missed? From what I read, all I am supose to do is put the chip into the slot, close it up, and turn it on. Or did I miss something that I should do?

You have the same model G5 iMac as I have. Check the manual that came w/your computer for detailed RAM installation instructions or check out Knowledge Base Article http://docs.info.apple.com/article.html?artnum=302506 iMac G5 (iSight): Installing and replacing memory (RAM)

RAM not being recognized on iBook G4

I have a late-2004 iBook G4, 256 mb of memory, 133 MHz, 12-inch screen .
I ordered 1 GB of RAM from Edgetech Corp. Their website assured me it would be compatible with my computer. The description of it is a PC-2100 DDR SO DIMM for Apple.
I've followed all the instructions I've found really carefully (and even went back and double-checked my work to ensure that the RAM was properly placed in there) but my computer won't recognize it. The DIMM I/J7 slot is still empty.
Does anyone have any idea what's wrong?
Thank you

Does your original stick of RAM still work? If so, and you know the new stick is properly seated and pushed all the way in and won't be recognized, then you could just have a bad stick of RAM. It happens. If you can't get it to be recognized, and the old stick is, then contact the seller for a replacement.
I don't know if there are any problems with that particular brand, but if the seller says it should work, then it should. Talk to them on the telephone to verify that it is the proper RAM, and arrange to exchange it for a new stick.
Good luck!

Acomdata 500gb External FW Drive NOT BEING RECOGNIZED!!!

I have been running an Acomdata 500gb FW External Hard Drive for my data intensive applications such as FCP and it has been working flawlessly for about the last year...
Yesterday I powered up the Mac and turned on the drive along with my external USB drive and the Acomdata drive turns on, lights up, and makes noise like it's working, but it is not being recognized at all by the Mac. I tried unplugging it, switching out the FW cord, changing the FW slot it was being plugged into, and everything else of that nature that I could think of. Of course the USB drive that has non-important work related stuff works just fine :/
So I'm wondering, does anyone think the drive has officially crapped out? It turns on and works so I can't tell. I'm PRAYING this is not the case, but I didn't know if there were any possible FW configuration settings that could have been changed or something like that. Any ideas?

Did you recently update to 10.4.10? Is there another computer that you can plug the external into to see if it's recognized? Have you tried plugging another FW peripheral into your main computer to see if it recognizes it?
Some people have had good results from the following:
1. Downloading and installing the combo updater of the system software update they've just applied via "Software Update...". In your case the update you need is at:
10.4.10 combo updater
2. Another trick is to restart each by zapping the parameter RAM:
Zapping the P-RAM:
After the startup tone, hold down <commandd><option><r> until 3 additional startup tones are heard, then release the 4 keys.
3. A 3rd tip would be to do Open Firmware resets on each:
After the startup tone, hold down <command><option><o><f> until the text screen is visible. When text can be entered, type the following commands, followed by the <return> key (there are no space characters in each command):
reset-nvram
set-defaults
reset-all (the Mac will boot up after this command is entered).
Also, see if anything in this Apple KB article helps:

External LaCie HD not being recognized after 10.5.6 upgrade?

My LaCie HD used for Super Duper backup is not being recognized by OSX. I also use a WD HD for Time Machine backup.
Before I upgraded to 10.5.6 i repaired permissions and backedup to the LaCie. Now when I turn on the drive, OSX does not see the drive.
I now see an icon in Super Duper in both the Source and Target areas called disk image. I have never seen this before. I do not see anything on my imac HD called disk image.
Any ideas?

Just to let everybody know that P-RAM reset resolved this problem.

Ipod touch not being recognized by itunes now

i have a friend who has an ipod touch....everything had been going fine for him and then all of a sudden it was not being recognized any more....what caused this? he did say that he had done an update but i'm not sure what version he has....could this possibly be the problem.....does anyone an a fix for this?

I think Apple is having a problem at the moment, my Ipod touch was always fine syncing until the new update! (Even on older itunes version, I could'nt sync since new update came out) It just isnt recognizing the device...
Ive done all that Apple says to do, none of which helps at all, I reckon its thier own side of the problem they need to fix...

IPod touch not being recognized by iTunes on my MacBook, and on 2 other PCs

Hello,
After scouring the web and these discussion forums to no avail, I've decided to post my problem. I downloaded iTunes 8.0 yesterday, and updated the firmware on my iPod Touch to 1.1.5. I tried connecting my iPod, and nothing happened. It is not being recognized by my MacBook. So, I tried using another USB iPod connector, and nothing happened. I tried using a firewire connector, and nothing happened. Frustrated, I tried connecting to my one roommate's HP laptop and see if it would get recognized there - no. I then tried on my other roommate's laptop. The device was recognized to be USB, but iTunes wouldn't go ahead and try and reformat it. I'm starting to lose my mind! I've tried resetting the iPod touch itself loads of times to no success. I've tried restarting while having the iPod connected to the computer, and still nothing.
What should I do now?

Sorry about not getting to you on the quick-fast, but we aren't Apple employees.
What ended up being the solution you needed, as you said, you couldn't find any information already posted on this problem, so documenting your fix may help someone in the future.

Video Ipod 80G 5th generation not being recognized by computer or itunes.

My ipod is not being recognized by my computer or itunes at all. I bought a new cable and nothing happens as well. however when i connect it in my car it works fine. did any resolve this issue? I am not sure if its the new software that has the issue but i am almost certain it is.

Many people are reporting problems with connecting there fifth-gen iPods after the update to iTunes 9. I had the same problem, and when I downgraded to iTunes 8, everything worked again.
I tried cables, resetting, and all the other steps. My solution turned out to be iTunes 9 itself.
My problem came from using a replacement hard drive-an adapter that allows me to retrofit my iPod with a Compact Flash card instead of a hard drive.
The problem is NOT the adapter. This system functioned perfectly until iTunes 9, and when I switched back to iTunes 8, it worked again.
Summary: I have a modded iPod, and it consistently works with iTunes 8, but not iTunes 9.
Reason: Apple is sooooooooooo afraid a Palm Pre user will be able to use iTunes that they are breaking the sync code on purpose.
Downgrading iTunes:
1. find the download of iTunes 8 for your OS. (not posting links, as they may change)
2. go into your iTunes 9, and export EVERY playlist to a text file. This is the only way to preserve your playlists.
3. Uninstall iTunes 9 from you computer, install iTunes 8.
4. Configure iTunes 8 to use your music folder (especially if you moved your music to a different location other than the default)
5. Add your music to iTunes-this may take awhile.
6. Import you text files and your playlists will return.
7. Backup your iTunes 8 library files.
Happily enjoy your modded iPod. Mac Users: Don't accidentally install iTunes 9 from an Apple Update.

HP office jet 8600, wireless not working, IP address not being recognized

Purchased new HP office jet pro 8600 N911a. Inserted CD software on relatively new Toshiba laptop using Windows 7, but problem is that printer IP address is not being recognized. Wireless router is Apple airport extreme. Have checked various potential solutions, including the following: deleting software and re-inserting CD, turning off router, computer, printer and resetting, running a wirless network test (no problems found, wireless on and working and connected), ensuring that laptop and printer are on the same wirless network (yes), ensuring that printer IP address is entered correctly, and ensuring that firewall issues are not a problem. Airport extreme settings show this printer's MAC address as a "wireless client" and its IP address as a "DHCP client"; however, when clicking on the "printers" heading in Airport extreme printers, no printers are listed (this is the pane that shows the USB printers connected to your Airport wirless device). Any suggestions would be appreciated

Hi,
Why don't you connect the printer wirelessly to your Airport Extreme?
You may do so by clicking the Wireless icon on the printer screen, click Settings and follow the Wireless Setup Wizard to connect the device, then it should recieve its own IP by using the printer capabilities..
If you prefer to use such a Print Server configuration, you may try using a different USB and check if that may help, otherwise I would suggest you to contact Apple as they know their accessories the best..

--FINAL QUERY
SELECT vendor_id, vendor_name, creation_date, last_update_date
FROM po_vendors v
WHERE v.end_date_active IS NULL
AND v.enabled_flag = 'Y'
AND NOT EXISTS (
SELECT 1
FROM po_headers_all h
WHERE h.vendor_id = v.vendor_id
AND h.creation_date(+) BETWEEN (SYSDATE - 365) AND (SYSDATE))
ORDER BY vendor_id DESC
Is it possible to send me the program so that it would be helpful for me to use it.
