Upgrading CPU board on sunfire V490

Hi All,
im trying to upgrade a sunfire v490 by installing a second CPU board.
I have the 1st board fully populated of 2 GB RAM in 16 slots (total: 32 GB) and the 2nd one containing 1GB RAM in 8 slots (total: 8GB)
However, im getting POST errors when i startup the server with both boards. I tried to swap boards among slots => same results.
Whenever i try to boot with each CPU board alone => no problems were found.
Kindly assist please if any helpful suggestion.
Regards

If all of the below requirements are met, then can you provide the POST output, so we can have a look?

Pismo CPU board loose

Hi!
I repaired a Pismo this evening. The problem was that it crashed when you touched it more than very gently, adjusting the display angle was impossible for instance.
What I did was to remove the CPU board and replace it and that solved the problem. Apparently the connector had come loose in some way.
So if anyone has a similar problem, don't throw you pismo away, the solution could be really simple.

If the cpu isn't properly reseated after, say, upgrading RAM, this can be a relatively common problem. It takes pretty firm pressure to properly seat the board, and (understandably) many are hesitant to push too hard. The trick is removing the RAM above the connection point before pushing (so as not to push on and break the RAM) and then using a slightly jiggling motion while applying steady pressure with two fingers directly above the connection point, so as to ease it down until firmly seated. When proper seating takes place, one should feel it settle in.

Mac Pro 2010 and Lion: buzzing noise from CPU board when idle

Hi all,
I have a 2010 Mac Pro with the 3.2 GHz quad core. I recently installed Lion and now whenever the CPU load falls below a certain threshold (approx. 10-20%) something on the CPU board starts to make a buzzing noise. It sounds like a capacitor or coil. Sometimes it is nearly impossible to hear but most of the time it is quite annoying.
Removing the CPU board and putting it back in, solved it yesterday. But after waking up the system this morning, the buzz was back again.
Also, this does not happen when running Snow Leopard or Windows in Bootcamp.
Does anyone experience the same issue?
Best,
b.lam

Then I would do a clean Lion install. Hopefully you saved the installer DMG.

Is it still possible to upgrade CPU on a G4 400MHz Titanium Powerbook?

I have a Titanium PowerBook G4 model (M7952) with a 17 inch screen, originally purchased in 2001. Over recent years I have successfully upgraded the hard drive to 128GB and the memory to 1GB SDRAM.
However, I have recently purchased Leopard and attempted to upgrade the system without first checking -and subsequently discovering - that my CPU speed is inadequate (currently only 400MHz, wheras required minimum for Leopard is 867MHz).
If anyone can advise me whether it is still possible to upgrade the processor on this particular model to the required specification for running Leopard - my initial searches have appeared to indicate this may not be possible - I would be very grateful.
Thanks, Steve

Welcome to Apple Discussions!
Even if it is possible, you won't be improving the system bus of the machine, so there will always be a bottleneck. Also software updates may not perform right, as the system is really only designed for built-in processor 867 Mhz or higher G4s, and not upgraded CPUs. Upgrade CPU support has to come entirely from the CPU vendor that supplies the upgrade for firmware updates, and compatibility. Essentially you will be creating yourself a jalopy. 10.4.11 is the max that will ron a 400 Mhz G4 reliably.

Can adding a patch disable CPU boards?

Recently, I installed patch#'s 118371-06, 126868-02, 139459-01 and 119059-46 (along with recommended dependencies) on a v880 running Solaris 10. The system was put in single user mode and the patches applied. However, when the system was rebooted, we were returned to the lom prompt and the message, "no usable cpu board in domain" was displayed. When our Sun rep arrived, he said the problem was that the CPU boards had been disabled. He generated a password, logged into the lom and did a, setchs -s ok for each card. My question, is whether one of the patches caused this condition or a separtate underlying condition brought it about. Your thoughts or similar experience is welcomed. Best regards to all.

Sorry I'm so late in responding ... I tried the displacement map a couple of days ago and had trouble using it. This tutorial is just what I needed. Thanks for the response!

Upgrade cpu with AMD A10-4600M in HP Pavilion dv7-6101er (lz661ea) FS1 and FS1r2 sockets

Hello Friends. I owner HP Pavilion dv7-6101er (lz661ea) and i want to upgrade cpu. Current CPU is A6-3410MX and socket FS1 i want replace for AMD A10-4600M socket FS1r2. But i don't shure will new cpu working in my notebook? I asked this question in ADM support, they said what both CPU is compatible, but need software support in bios of specific models of notebooks. I can't ask this question in HP support because free support time of my model is ended. Please prompt - BIOS of my notebook will support a new CPU?
This question was solved.

All my notebooks have been made HP I always helped the company - buying its products, help you and me now. I'm not asking for much - just a concrete answer - will work or not?
No!! That is where you are wrong. I am not an HP employee.

There is no concrete answer on this. Sometimes an upgrade to an unsupported CPU will work, but most often it will fail. Read my previous posts. The risk of whatever currency you use in your country to purchase the new CPU is yours, not mine nor HP's.
Here is a solid answer for you...Use a CPU that is in the list in the Maintenence & Service Guide and your upgrade success chance will go up dramatically. I cannot say your upgrade success will be guaranteed because there is always the chance that you may break something during assembly/disassembly or be unaware of a critical assembly/disassembly procedure and inadvertently destroy your new CPU.
If you want a high performance CPU and chipset in a laptop then choose well when making a laptop purchase. Laptop/notebooks are actually not meant to be upgraded.

Is Firmware chip on motherboard or CPU board?

On a Gigbit Ethernet Power Mac G4 and a Cube for instance, is the firmware chip located on the motherboard or CPU board? I want to put a Dual 500 CPU board in my Cube. The G4 tower firmware is 4.2.8, while the Cube is 4.1.9. Probably won't matter, I was just wondering where the firmware resides. Thanks!

The computer's firmware is stored in a chip on the motherboard.

Upgrade CPU AMD E-300( 1.3ghz) for laptop HP 2000

Can I upgrade CPU for laptop HP 2000 .? change CPU for this...? impossible.?
Thanks a lot...I want to help

Hello santalucia1992. I understand you're wondering if you can upgrade the CPU in your notebook.
On some models of notebooks it is possible (though, not recommended) to upgrade your CPU. The problems you could run into are heat concerns and power consumption concerns. The cooling system for the notebook was designed with specific parts in mind and a faster CPU will create more heat. Also, the notebook's power supply was meant to handle a specific amount of power as well. A faster CPU will generally use more power. Also, some CPUs are soldered to the motherboard. This means that replacing the CPU means a full motherboard replacement.
In order to look up more specific information about the notebook I'll need your product number. I can use this to view what parts are available. This will give me a good idea whether or not the upgrade is possible. This document can show you where the product number is located.
I will keep an eye out for your response. I hope you're having an excellent day!

Upgraded CPU = Fried board? or PSU?

I just upgraded my KT4VL board from a 1700 XP to 2400 xp cpu. It booted right up, i changed the FSB to 133. It ran for about 2 minutes and the speakers began broadcasting a clicking sound. I pulled the plug and now cannot get it to boot. Tried clearing bios, replaced old cpu, tried different PS, tried different cpu fan, pulled all hardware and reattached. My day sucked! Any ideas would be great.

I'm wondering if your psu fans are coming on if they are not comming on then try this to reset the board. Tools needed is a wire with two sharp ends on them.
Start you may not have a power override on yours thats why a wire is needed
WARNING: Check the Power Override switch situated at the back of the machine just above the connector for the power cable. If this switch is activated (switched to on), no power will be supplied to the system.
Power off (unplug) the system unit.
Check the power cord for continuity. Replace if necessary.
Check for the correct line voltage from the power outlet, and verify that the voltage selector switch (if present) is set to the correct voltage.
Power on the system unit.
1. Does the power supply fan run?
If Yes, go to step 2.
If No, go to step 3.
2. Does the system fail to shut off when the on/off switch is pressed?
If Yes, read ahead.
If No, go to step 3.
1. You might have a damaged on/off switch cable assembly.
2. Disconnect the on/off switch cable assembly connector from the power supply connector and take an ohm reading.
3. Go to step 6.
3. System shuts off when on/off switch is pressed.
1. Disconnect the power cord from the back of the system unit.
2. Disconnect all power and switch cable connectors from the system board and the power supply.
3. Disconnect the power connectors to all drives.
4. Connect any one of the power connector to system board or drive as power load for driving up power supply.
5. Reconnect the power cord and turn on the power supply.
4. Does the power supply fan run?
If Yes, read ahead.
If No, go to step 8
1. With the system powered on and the power supply fan running, check the voltages of the power supply connectors for the system board and all drive connectors, as shown in the following figures.
5. Are the voltages correct and does the fan run? (
If Yes, read ahead.
If No, go to step 8.
The power supply is working normally.
If you suspect the on/off switch cable assembly, see Step 2.
If the fan continues to run when all connectors are plugged back in, go to See Undetermined Problems .
If the fan stops running when a drive connector is plugged back in, go to Start .
6.If you have an OHM reading when the switch is pressed and an open reading when the switch is released.Replace the on/off switch cable assembly.
IF Yes, read ahead.
If No, go to step 8.
7. Replace the system board
8. Replace the power supply
ok now the wire thing if no fans are running with the atx power off and while still pluged in the board push one end into a orange wire and the other on a black wire hold untill the psu fan comes on. you may have two orange keep trying untill one of them works. I have done this with a few computers that people thought were dead and actually it just needed to be reset. Not many people know of this unless they went too school.

MSI KT8 Neo2 F board, upgraded cpu and used MSIs Live Update, now unstable BSODs

I've had this mobo for almost 2 yrs now with an AMD 3500+ cpu and recently upgraded that to the FX-55. To do that, it required using MSIs Live Update and needed newer chipset drivers. It has the latest bios according to Live Update.
It took a few attempts but finally booted w/o BSODs and has been running for over 1 week BUT is still not right. It's sometimes unstable and will crash (BSOD) just by starting up a browser. I had the bios settings at "optimized" and have tryed a few other changes but so far, I'm not gaining. Last night I couldn't keep it running more than a few minutes w/o it crashing.
I have the MSI manual for my board and plan to spend some more time playing with it tonight but might anyone here have any ideas? It's not running hot (reads 50C) and was stable before with the 3500+. I've tryed "Fail Safe" bios settings too but nothing's better that way either.
I'm hoping that someone here has a few ideas?
Perhaps related?
After initially running this with the new cpu, I'd see the "searching for MAC address" message and it'd hang there on boot. Someone told me that was because it was trying to do a network boot, selected in the boot sequence SO I've unselected that and that's when things got worse (oddly as it shouldn't IMO). One can select the 3+ boot devices (floppy, USB, CD-DVD rom, HDD) and it use to see the HDDs (2) before but now I'm not (only floppy and CD-DVD rom) and if I unselect the ethernet option (boot other devices), it fails to boot at all and says "insert floppy" as if I was installing Win98 way back when (running XP Pro btw). Something's definately not right with my bios selections.

Let's go back to basics here for a bit. Start by posting your complete specs in your signature like we do. Make sure that your PSU values are also in there.
Let's also look at some tests to help determine where the issue is. I would recommend Memtest86+, OCCT, Prime95, and 3DMarks as a great first series. Also get CPUz and lets see what it shows for CPU and Memory.
If we can get an idea where things begin to fall apart then maybe we can determine if this is driver, hardware or some other issue without having to make the flash happen first. The reason why I am avoiding the flash at this point is that if things are mostly working maybe there is some other cause than Bios. We know that some FX's work with 3.x and some that don't. So I would like to try a bit of checking before we dive into a flash that could cause more issues than it solves if we get this wrong. As things are mostly working now we can assume at least for the moment that maybe the flash is not needed. If we don't see anything during testing that sheds some light then maybe we go ahead with the flash.
That is if your willing to take some time to try and sort this out and maybe learn some stuff in the process. It is of course your call and we will respect whichever decission you make here.

Trying to upgrade on board Cpu to an AMD FX Black 6300

Hi,
I currently have AMD Phenom II X4 810, the stock cpu that came with the desktop. I want to Install an AMD Fx Black 6300. My bios version is 5.02. I don't know if that needs to be updated? If so where can I do that? There is a list of compatable cpu's. If thats the case i cannot use this cpu in my desktop?

According to THIS PAGE, the upgrade processors are:
TDP=125W
AMD Phenom II X4 9xx/9xxe/8xx Quad-Core (D)
AMD Phenom II X3 7xx/7xxe Triple-Core (H)
AMD II Athlon X4 6xx/6xxe (P)
AMD II Athlon X3 4xx/4xxe ®)
AMD II Athlon X2 2xx/2xxe ®)
The AMD FX 6300 is not on that list. Unless someone gives you a modified BIOS, it is not likely to work.

Replacing 2 CPU board with 1 CPU board in MacPro4,1

Does anybody know if it is possible to replace the complete dual CPU processor board (tray) of a MacPro4,1, with a single CPU processor board of the same model? I do not wish to use 2 CPU's anymore and downgrade to a single CPU to have more and cheaper upgrade options. Thanks!

I've done a bit more research here and stumbled over the following.
The MacPro4,1 (early 2009) apparently ships with 2 different Backplane boards:
Ver. 1 p/n: 661-4996, EEE codes: 1LT, 7A1
Ver. 2 p/n: 661-5444, EEE codes: CU7, DD4G, A71 BH7
The 8-core Processor board: p/n: 661-4998, EEE codes: 1LU, BXZ, DCVH
The 4-core Processor board: p/n: 661-4999, EEE codes: 4MF, BY0, DCVJ
According to the above, there is no specific Backplane for the 4-core or 8-core Processor board. So the Processor boards are interchangeable.
What I don't know yet is the difference between ver. 1 and ver. 2 Backplane boards:
According to some readings, the best way to find if a part is correct is to match the EEE code. My 8-core Processor board has the following Barcode:
J5906F1UH1LUB, which means according to xxxxxxxEEEx, the EEE code is 1LU. And the link below suggest that 1LT should be the corresponding Backplane board. I obviously have a ver. 1 Backplane board.
Does anyone know the difference between ver. 1 and 2 Backplane boards?
What 4-core Processor board would be a match for Backplane with EEE 1LT?

The cpu is NOT soldered to the motherboard so a simple replacement should be fine. I see that your laptop uses only the shared graphics chip from the cpu. I would consider a board replacement too. There is listed a motherboard with a dedicated ATI Radeon 7670M with 1GB or 2GB of RAM. Component replacement procedures start from page 38.
