Northwood 3.06 HT CPU question

[Jay06S]

Also posted on Motherboard forum..

I know this is a very old board, but it has served me very very well, and just keeps on going. I purchased a 3.06 Northwood Hyperthreaded CPU with sSpec that is appropriate for this MB, but after installation (goes it fine), the system will power on for only a few seconds and then shutdown. I can never even get to BIOS. Am I missing something than anyone can think of? The Power Supply is more than ample, the MB supports HT, I'm on the latest BIOS revision for the board P10. Oh and the seller is no longer registered on Ebay, so I'm assuming I got a bad processor. I just didn't see anything on the manual for the MB that talks to an immediate shutdown scenario.. I'm glad it is there as a protection mechansism. I plugged the 2.4 socket 478 CPU back in and systems comes right back up. Any thoughts at all, or just write it off as a really bad experience... I can't think of anything else to try. Thanks ..

Yep, that board definitely supports that cpu so if the 2.4 still works and that one doesn't then I'm afraid you have a bad cpu.

Check the S-code...hopefully it's a retail chip and if you are lucky Intel might replace it for you.

You've got the 533MHz FSB (133FSB Quad-pumped) CPU? Does your board support 533FSB? Isn't the 2.4GHz 800FSB? The 3.06GHz 533FSB w/ HT is in somewhat weird position. It is the only CPU that supports HT among 400/533FSB. What exactly is your motherboard?

The D845PEBT2 board is definately a 533 FSB.

Beachboy,
Thanks. I figured it is probably the CPU. I just assumed it would at least get to the point of a Beep Code in BIOS, and not just shutdown. I'll double check the s code, but think it is an OEM code. Without a receipt and retail box though, I don't think there is much Intel would do. Not sure even with those there is much Intel would do at this point, as I think the chip is discontinued...

I know it's not much of an advice but you could check if the pins aren't bent/broken on the CPU. I guess you already tried obvious things like CMOS reset? What was the previous CPU installed on the MB? Cause if it was an FSB800 then ofc the FSB currently set can be a bit much for this new CPU of yours.

No bent or broken pins that I noticed beforehand. I did the "Credit Card routine" up and down the rows criss-cross to get them as straight as possible. I guess I'll go back and give another look at it, but looking at it without a magnifier all the pins seemed good, and the processor went in relatively easy.

I did not reset CMOS or BIOS Pins option to reset. I don't recall reading that as being necessary. The CPU in there now is an older P4 2.4 Northwood family chip. Intel CPU ID reports it at 533 FSB. You have me wondering if a BIOS reset should be performed or not?? I would have thought that the BIOS would have automatically recognized the new processor (at least that is the way it seems in documentation). It is something else to check on though unless others have a thought.

Thanks for some additional thoughts.

As long as it was a 533 fsb 2.4B that was installed at first, you wouldn't need to reset the BIOS. That would only be required if you have a 200 Mhz (800 in Intel's terminology) fsb 2.4C. Of course, it wouldn't hurt anything to give it a shot. It just more than likely isn't going to change anything.

you should reset CMOS a lot people don't think so but give a try !! good
luck!!

Myocardia,
Yes.. it is a 2.40B that was and is now back in the socket. I've got no concerns about resetting the BIOS, but from what I'm seeing here, I'm not sure, as you indicate, it is going to change anything. I am not getting an apparent BIOS error. No beeps, no BIOS screen or error message, just an almost immediate power down. I would imagine that I'm trying to be told something when the system knows enough to shut itself down. With the 2.40B, the system comes up immediately. Any other HW changes have always been immediately recognized.... Just wish there was something truly obvious, other than what appears to be obvious.. a bad CPU. Thanks.
