System profile shows 333 speed after 400 logic board install

I have a Lombard 333 mHz computer. I bought a 400mHz logicboard with DVD support on e-bay. I put the board in, reset the PMU, zapped the PRAM and my system profile shows a 333 mHz machine speed. Does that mean I don't have a 400 mHz logic board, or is that machine speed in system profile refering to something else, like the daughter card?

Yeah Jpl is correct. I am about to do the opposite and install a 333 CPU on my 400 lombard. My l2 cache bit the dust so i am doing that for a cheap alternative so i still have a portable computer and am buying a 400 MGHZ g4 tower to use as my main workhorse now.

Terrible Signal After New Logic Board Installed

Hello--
I recently (about a month ago) had a faulty logic board replaced and my OS upgraded by the repair shop from 10.3.5 to 10.3.9. My signal strength before that was consistently 100% and the internet was fast. Ever since I got my computer back, my signal strength has been at best 30% and often drops out, and the internet is intolerably slow. Two other computers in the main house (I live in a granny unit), both PCs, access fine with decent signal strength--nothing has really changed for them. I have often restarted the Linksys Wireless-B router over the last month when signal drops out for me, and that reestablishes a connection with my iMac, but signal is still awful. Is there some preference folder I ought to throw out since my OS upgrade? What could have changed?
Thank you, I know this is probably vague.

The easiest thing to do is double check the Airport card to verify that it is seated properly. If it is, it could also be that the tech didn't re-connnect the antenna to the base of the card.
Check those and if nothing changes, give Apple a call and have them take another look at it.

Roland UM-ONE CD-ROM does not mount on iMac OS 10.8.2 Roland driver for 10.8 installed as directed. No power ready light shows when connecting UM-ONE. System Profiler shows it, but not configured. Older UM-1X works fine. UM-ONE works on Dell Windows XP.

UM-ONE
Roland supplied CD-ROM does not mount or read by iMac OS 10.8.2, works with old TiBook and Dell laptop, however.
Got latest driver from RolandUS.com (um_1mx8d_v100), installed as directed.
No power ready light shows when connecting UM-ONE.
System Profile shows it there, but not configured.
With Audio MIDI Setup opened to MIDI Studio window, UM-ONE does not appear.
Tried many things without success. Tried swapping UM-1X (formerly on Dell laptop) with UM-ONE. UM-ONE installed and worked there without any issues. MIDI instrument communicates fine.
The UM-1X works without complaint and as expected when connected to any USB port on either the Dell or iMac, even a hub or keyboard port, just as it formerly had before changing operating systems, etc. It is old, but reliable.
Upshot is, for now, that UM-1X works with either the Dell or the iMac, but is currently attached to the iMac. UM-ONE (2011 model) only works with the Dell (Windows XP).

Same problem here! The only difference is that I'm using a MacBook pro 13 inch (2011)

I've a Quad Core, System Profiler shows 8

Maybe a dumb question, but why, when clicking on the CPU usage (Command 2) does System Profiler show 8 columns? What (simple thing) am I missing?

Hyper-threading. It lets one processor run two threads, so while waiting for data from memory, it can switch to the other thread, whose data may already be in cache. The operating system sees the processor as if it were two processors.

Does System Profile show PCI-X

I have a
Apple Power Macintosh G5 2.0 DP (PCI-X) with an
Atto UL4D Ultra (320MB/Sec) SCSI Adapter in 133MHZ PCI-A Solt 4, and
3 external Fujitsu MAX3073NP 73.5GB 15000 RPM 8MB Cache SCSI Ultra320 68pin 3.5" Hard Drives.
System Profile shows only PCI Slots not PCI-X?
Atto Configuration shoes the UL4D adapter locattion as PCI not PCI-X.
Max Data transfer from Ultra SCSI drive is ~ 90MB/Sec - expected ~ 320MB/Sec?
Any ideas on how to verify the 133 MHZ PCI-X Slot?

Horror after new logic board installation.

Hello,
I have an older 2008 MacBook Pro 2.5 GHz 17" computer which after years or erratic behaviour (overheating and black screen after that) forced me to buy and install new logic board. I've done it myself due to my extensive (unfortunately) experience in baking the old board. All went well. The computer booted however it took very long time to actually load the system. After 20 minutes or so I interrupted this and switched off the system. After switching again it booted quicker and loaded the system as normal. Long story short. All the components register properly under system profiler. However both firewire ports don't mount my external hard drive. The drive works perfectly with other computers. The drive (Lacie) when connected to either port (400 or 800) spins up and indicates connection made (blue light is on). I can even hear it mounting but it never shows up on the screen. The computer literally doesn't see it even after Finder relaunch. I've followed all the usual resetting procedures found on the internet with no results. Same problem with ethernet. It shows in the system profiler, after connecting cable computer sees it but no internet connection is made. The network setting says: self-assigned IP ... and shows orange indicator. I never had any of these issues with my old logic board. Again here I've done all the resetting with no results. Before coming to this forum I've spent the entire week trying to figure it out.
Can somebody please at least point me in the right direction as to what should I do.

This is after replacing logic board with new one.
Actually there are no NEW 2008 MBP logic boards. Apple stopped having them made sometime in 2008 or 2009. All that are available now are used, reconditioned and or left over stock (but I doubt that). Seeing as the 2008 model had a recall for failed nVidia GPUs all of them have been baked and or reflowed.
So it seems the current replacement 2008 LB you have is also faulty.

What happens after a logic board replacement?

After a logic board replacement will my hard drive be erased? If so, can I simply restore my entire system from backup using Time Machine? Thank you.

Your hard drive won't automatically be erased, but some commercial applications may refuse to work, and a very small number of preferences won't be carried over.

Will the IMEI no. of Iphone 4 will change if board is changed? Also is there a check in Iphone that it has original Logic board installed on it.

Serial No. no longer shows in system profiler after new logic board..!

My Macbook had to go in to my Apple Service centre to get the random shutdown fault fixed. They fitted a new logic board and last night I noticed that the System Profiler no longer show the computers serial number. Instead it says "systemserialnumb" where before it listed the Macbooks serial number. Does anybody know whether this will affect my 3 year Applecare warranty as normally they check your machines warranty status by confirming the serial number? I have all the documents but would not normally carry them all if away from home.

I love this board..ask a question and someone always knows the answer..! Mort..thanks, at least now I know it has happened to other people and also that the serial number is also to be found under the battery which for repair and service purposes is good. I am a little surprised that the engineers don't routinely reset it at the time of repair though as it is one of the pretty relevant bits of information in the "about this computer" button.
thanks

MacBook Pro Retina showing spinning ball issues even after Main Logic Board Replacement

HI there!
I'm a proud owner of Macbook Pro, 15 inch, late 2013 model. It has 2.6 GHz Intel Core i7 processor; 16 GB Ram, 1 TB PCIe based SSD. The software version is OS X 10.9.4. I have AppleCare.
1. MY mac developed rainbow beach ball issues. Sometimes it'll last for ages. I took several videos of them. I spent hours chatting with online Apple advisors. They did everything they could possibly do: Repair Disk, Repair Disk Permissions, SMC reset, PRAM reset. When nothing worked, I did clean-install the Mac six or seven times. Every time other apps would randomly cause the spinning ball issues. My Mac even restarted all on a sudden because of kernel panic. So at last, I took it to an Apple Store which is a one-mile drive from London. They diagnosed it as a graphics issues and replaced the Main Logic Board and put it to standard testing which revealed no other anomalies. After the repair, I noticed that dock icons remain present for a dew seconds when I restart or shut down the computer. So this time I took it to a London Apple Retail Store. The Genius at first diagnosed it as a display burn-in issues and sent it to be replaced with a new one. However, next day the technician who actually worked on the computer, phoned me saying that they could not reproduce any issues and did not replace the display either. I went to take my Mac back and discovered that the dock icons stuff still persist when restarting or shutting down the Mac. When I drew their attention, they told me that it was a software issue that Apple is aware of. Apple might resolve the issues in the future updates. Well, after getting back to my hotel room, I clean-installed my OS from USB and the dock icon issues were gone. Same version of software, but different behavior.
2. But that's not the reason I'm here. My Mac has again begun to show the rainbow beach ball one day after the repair, when I try to connect to my Airport Time Capsule through Finder in order to selectively transfer files to my Mac. This time the spinning ball would last for a very short time. But if I want, I can regularly reproduce them. I've also noticed this when installing MS Office for Mac 2011 edition. I'm sure I'll get the nasty ball as I use the Mac more and more.
3. I've got some questions: Can it be that during the MLB replacement, some other connectors got harmed? Or the issues are not specific to graphics only? Why didn't Apple find any anomalies during testing? I'll go to Apple Retail Store again, when I get the chance to. Once there, can I ask them for a full replacement of the Mac? Shall they take my request otherwise? I really don't feel comfortable using a shouldered computer which is going to go through many parts replacements.
4. I sincerely need your feedback. Please help me guys out there.

Applecare was no help at all. I called and did the complaint. They confirmed that it is registered to me and everything but essetially told me that they cant give me answers as to what is taking so long. They knew a repair was in progress but wanted to set me up with an appointment at an apple store? (the nearest Apple retail store is Billings which is 240 miles away, or about 4 hours). i tell them its at the repair place and they go on to tell me they can send me a box to mail it in and have it reapir by them.. They are trying to shift the blame to the AASP and his rep. But he said he has been trying with very few answers from Apple as well

System Profiler shows no boot volume

I have a G4 imac and I'm trying to upgrade to Tiger. It meets all the reqs and the disc is the retail full version installer. The installer freezes at the select destination screen. It shows the harddrive but it is faded out and I get the spinny thing. In the System Profiler the boot volume under Software Overview is blank.
First question is: That shouldn't be blank correct?
Second question is: Why is it blank?
Third question is: What do I do about that?

IMac G5 serial number missing after main logic board replacement!?

After replacing the main logic board on a 15-days old brand new iMac G5 2 GHz 20-inch TFT, the computer serial number no longer shows on" Apple ()/About this Mac" or on "System Profiler/Hardware Overview/Serial number".
As far as I know that is normal, but my question is: is there a way to show the serial number (old or new) again? Resetting the Firmware perhaps?
Thanks.

I got a new serial number sticker to put on the stand base. It also inckuded the new MAC Address for network use.
I would call and see if they can send you one.

But since techs are not themselves given (allowed) too much information, my feeling is that some of them do things in a different way, depending on how they understand it.
AASPs and Specialists do not alter serial number information in any way whatsoever, including transfer or assignment of serial number to new components. They are not given the proper tools to do it, and thus aren't supposed to hop into NetInfo or a text editor and change language project strings.
The French serial number assigned erroneously to that fellow's board got there because it was a refurbished board whose original serial number had never been wiped or Apple themselves assigned the wrong number, not because an inattentive service tech did anything wrong.
Now, if some service tech DID decide to take it upon himself or herself to hack a serial number there, you still need to contact Apple, 'cause that isn't supposed to happen, and you still don't have a proper serial attached to the board.
Believe me on this one.

Time Machine Restore After New Logic Board

Older iMac (2009) had hard drive and logic board replaced. Running latest system (10.10.2) before and after logic board replacement.
When attempting to restore from a Time Machine backup made prior to the new logic board, although the iMac sees the Time Capsule and the "Data" file, attempts to proceed with the restore are met with error message "There was a problem connecting to the server [name of Time Capsule] - contact your administrator."
Any experience with this issue? Anybody successfully perform a restore following a new logic board?
Thanks very much.

I would refer you to visit Pondini's Time Machine FAQ for help with Time Machine and full system restore. It also provides instruction on how to restore a backup from another system or Time Machine backup drive.

Time Machine doesn't recognize old sparsebundle after new logic board

Installed new logic board in pre-Isight 20" iMac due to capacitor swelling and kernel panic. I had also erased the internal HD. I was able to restore all my files to internal HD from Time Machine backup on the 1TB Time Capsule. Now I'm trying to back up my restored iMac to Time Capsule, but there is insufficient space. Time Capsule has three sparsebundle files: one for the 20"iMac prior to new logic board, one for a Powerbook, and one for a newer 24"iMac. Time Machine wants to create a new sparsebundle for the restored iMac, but there is not enough room and I would like it use the residing sparsebundle so that I will have backups prior to the point the new logic board was installed. I tried just changing the name of the old IMac Time Capsule sparsebundle file to the new sparsebundle filename that Time Machine creates when attempting backup, but that did not work. Any suggestions?

1. I thought of just deleting the old sparsebundle in order to make room, but it was a less elegant solution because: a) I'd have to do a complete (i.e. lengthy) backup when really only a few things have changed (mostly software updates) since the restore. b)if something should go wrong with that process, then I've lost my backup file to restore the computer. True, I could archive the old sparsebundle to another drive, and then delete it from the time capsule, but somehow I think there should be a quicker, less labor intensive way that doesn't involve bringing in another hard drive.
2. I believe you can restore any Mac with any time machine backup. If you boot from the system disk, go to utilities, and select restore from time machine backup, it then allows you to pick any of the files on the disk that time machine has backed up to. After all, even though Time Machine thinks this is a new computer, the restore that I just did makes it essentially the same computer that I had before the failure of the logic board--the desktop looks exactly the same. BTW, the Apple authorized service center that did the logic board replacement had put a clean version of 10.6 on the internal hard drive, and I was unable to use that system to do the restore--it just hung up. I had to do the restore using my system disk CD (and basically downgrading to system 10.5.8)
