Xeon E5472 problem on P5B Deluxe

[Xevipiu]

Do you have the P5K bare, the Vanilla one?
Have you updated the BIOS from here? http://genius239239.myweb.hinet.net/771/

Put Strapp 400 on it and with the 1:2 divider (800)

I also have P5K, P5k Deluxe, P5K3 Deluxe and a Blitz Extreme (All P35 chipset)
The truth is that there is no problem, you are doing something wrong

Well, it's very simple. Cobito and I have the same micro. As far as I know, you don't. We contribute here the sensations and experiences that we have with knowledge of the cause, first-hand, without NASA engineer titles, to be clear.

I've commented that I have problems detecting SATA ports when I overclock the micro. It goes up and turns on, but obviously it's useless to me without a system to boot. I've tried all possible configurations and it hasn't worked. My chipset is the G31, in case it's of any use to you.

If you comment that indeed the problem is the lack of a high multiplier due to the limitation of the FSB on the boards, then there's nothing crazy about what I said earlier, which is to try with boards that allow more play with micros with low multiplier. You've said so far that it's silly to buy this model of micro and that we should buy another one, a very constructive contribution considering that this thread is specifically about the X5472, which we already have and with which we want to deal at this time.

I understand that you can't do more, that it has to do with it being an x5472 in this case, they are all Yorkfield, in this case E0.

The causes can be many, but as a general rule the board shouldn't have problems if it's done correctly,
I doubt the FSB limitation, it can work quietly at 430/450FSB without touching the north voltages. especially the frequency of the PCi_E is set to 101mhz.

I have few Xeon E0 and C0, to date none have given me problems: E5420L, E5430, E5440, E5450, x5450, x5460, 5470, (x5260, x5270, x5160, etc...* )

And I understand that you're stuck, because precisely Cobito's has a different stepping than mine, his is a C0.

Starting from the base that as you rightly say the causes can be many, here we are two with problems to raise it above 3Ghz. Of course there is the possibility that we don't know how to do it, although it could also be a coincidence that this micro gives us problems to both of us in parallel.

Apart from that, as already mentioned, in two of the four tests, we both had a socket pin broken, so maybe apart from not knowing how to do it right, that was also holding us back, which is not to say that it has to be the cause, I leave those conclusions to more experienced forum members and/or with less aptitude for communication.

I understand that you have a finger up your ass. If you mention that you have a pin, you just have to identify which one it is, to know if that pin affects you physically, there must be no diagrams of socket 775 on the net, there is nothing that can't be solved.

Apart from the pin, you just have to keep trying possible causes by elimination, there are symptoms that you clearly identify where the problem comes from (you can also use any other 45/65nm processor to see if you have the same limitations).

Less or more aptitude for communication, it's misinformation without knowing what you're talking about

Gentlemen, let there be peace...

@xevipiu And so we did, but we achieved nothing.

For my part, I leave the topic. A broad knowledge of hardware and/or software does not exempt anyone from having education and respect, nor from knowing how to use basic notions of conversation in any area of life. We are people before experts or technicians.

As I am testing 6 Ati X1900 series graphics these days, which only have support under XP, and only with cards with native Gen1 support, I have tested one of the Xeons with one of my old P35s

@xevipiu I see that's the P5K Deluxe. Could the instability I'm experiencing be due to the southbridge then? Because apart from the DDR2 memory I use, I don't see any other difference.
