MB= MSI P6N SLI
High quality power supply.

The board and the replaced cpu work. I decided to upgrade the psu and bought the Intel E8200. Power comes on but the board does not post. I have looked on the MSI site and do not feel their advice is appropriate because the board works with the older chip.

I have upgraded the bios to the version that is supposed to work with the E8200. I do not know what to do. Any advice would be appreciated.

..well, what PSU are you using? Also, check if you have ALL cables plugged in when you attempt to POST. Make sure you have the EXACT bios you need.

Pretty much try to double check everything.

P.S. Do you get any beeps? If so, check your manual for the meaning.

The does the PSU have a 4 or 8 pin power connector for the processor power plug? if it's only a 4 pin, you may need a new power supply.

The psu is an Enermax 535watts.

I am sure that I have the correct bios because I have been to the MSI site and they seem to recommend version 25 which is what is not in the machine.

I think all the cables are correct because the only thing I have changed in the cpu. I am currently using the same computer with the Smithfield and it works.

R53843, I have seen this before. Do the following:

1) Find another Penryn compliant system to test your E8200 CPU to verify it is not defective. Even some computer stores will help you out with that.

If the CPU is fine and works in another system, continue:

2) The following situation occurred when I built a friend's computer two weeks ago. I had changed out the CPU (from C2D Conroe to a C2D Wolfdale). As a result of the CPU change, the VMI pool image was reset and the motherboard was not able to POST. One of the side affects of the VMI pool reset was that the memory voltage settings had been set back to default (1.85V). The memory installed on the motherboard was Patriot high performance memory that required the use of 2.2V. The system would not POST because the voltage had been set back to 1.85V. So, I had to remove the memory and use regular 1.85V DDR26400 (800) memory to post the system and change the memory settings manually. This is a known issue with some of the DDR2 memory that requires a default voltage of 2.2V. Most motherboards can not detect this requirement through the memory's SPD values. Once the regular memory was installed, the system posted perfectly and I was able to enter the BIOS and set the memory voltages and timings manually. I then selected "Save Changes and Exit". After the restart and I received a successful POST again, I manually shut off the computer and removed the standard memory and put the Patriot memory back into the system and all was well. The system posted normally thereafter.

I hope this helps with your problem.

Nobody asked what the old CPU was?

The e8200 has an FSB of 1333 which will require 667mhz DDR2 to boot. Have you got 667mhz RAM or higher? Cause if you dont its not gunna work... the reason the old CPU will work is if its a 1066 or even 800 FSB the DDR2 533 or 400 will post fine.

Good point chookman! It is important to note what exact Smithfield CPU is posting fine with R53843's system. The MSI P6N SLI motherboard does natively support both 1333Mhz and 1066Mhz FSBs.

But we are in agreement, the problem is most likely being caused by a memory compatibility issue.

Worst case scenario, his E8200 is dead...

I have checked my memory on the Corsair site and they advise:

So it seems to me that the cause is not the voltage.

The LGA775 Smithfield is the Pentium 4 805 dual core.
The memory is ddr2 800mz

I put the e8200 back in last night and it caused the hd to crash. It had to be sorted by fdisk in ubuntu, so I am wary about putting it again before we have uncovered the reason for the failed posting. What are other things could be causing this?

^You probably need to set voltages,etc manually.

Perhaps you miswrote this? Is version 2.5 the version *in* your machine, or *not in* the machine?

What exactly is their advice that you do not feel is appropriate?

Version 2.5 of the bios is installed. I mistyped the statement above.

I am trying to draft a full reply to the question above about what part of their advice does not seem appropriate. Everytime I click on postreply there is a message this thread does not exist. I thought I had logged into this forum, but may be I misunderstood. Why does the error message result?

MSI's advice on post problems are as follows. I have commented on them below but I wonder if in fact some are relevant to me. Your comments would be appreciated. Which ones should I concentrate on?

" • Power supply issue"
Power supply sufficient
" • BIOS problems"
I am using the latest
" • Non supported components"
E8200 supported
" • Diagnostic codes"
I am having some bleeps when the machine is started but not with the E8200 in the machine.
" • Jumper settings"
Jumper settings for FSB do not apply to the Intel boards
CMOS jumber is set correctly otherwise the current smithfield would not work.



" • Shorting issues"
The board works with the sithfield
" • Component related issues"
I have not checked this because the components are working with the smithfield.

No Boot (system does post)
" • Hard drives not detected"
They are detected with the smithfield
" • Hard drives are detected at boot"
Ditto and the the Hard Disk drive stays on all the time with the e8200
" • SATA configuration"
My current set up works with the smithfield
" • RAID controller configuration"
Ditto and my raid card is not the boot disk

^To support FSB 1333 you need to manually set the FSB.

So try this:
Go to BIOS (using old P4) ans set Multiplier to 8.
Set FSB to 266. Save and shutdown (turn it off manually once the PC try to re boot.
Put the E8200 in and boot ans see.

I would certainly look into this; remember, the machine also does not work right with the E8200 in the machine. Google for "BIOS beep code" or similar.

Just so you don't feel you're all alone in this, I know others with 650i chipset boards are also having mysterious problems with the new 45nm CPUs. Intel *did* make some changes to its 45nm CPU electrical specs after the 650i/680i chipsets came out, so I would prepare yourself for the possibility that it will never work on your MB. When you are researching your next MB purchase, keep in mind that the chipset will play the biggest role in performance, stability, and compatibility with future CPUs.

My ami bios seems to have different terms to yours. So could you please comment on what I should change.

The FSB can be changed to the full 1333 by directly putting that figure into the box. It does not seem to have a multiplier box.
It has an adjustable entry for CPU ratio. Currently at 20
Also for PCI-EFrequency at 100

Currently the CPU frequency is 2.666 (20*133
