Xeon E5472 problem on P5B Deluxe

I think it's a matter of the FSB. That chipset reaches a maximum of 1333 mhz according to the manufacturer, so theoretically everything you put above could produce instability.

My Asus P5KPL-AM EPU does support the FSB at 1600 (OC mode according to Asus), and the system stability is full. However, being designed to go to 1333, the 1600 are a luxury allowed but not imposed. That's why I don't scratch even a MHz more than the native 3Ghz to the micro.

In the end I think we will have to invest in top-of-the-range boards to get the most out of these gadgets...

Best regards!

What nonsense you say, if you don't know what you're talking about, it's better to keep quiet

I have two 965i, one P5B Deluxe and one Commando, both reach perfectly up to 2000, which are almost 500FSB effective, that means you will be more than enough with 420/430FSB with your motherboard, that is why it is so important that the processor has a high multiplier, since if it has a Strapp of 1600 native, it means that it will use a low multiplier.

Here you have the example of one of my Xeon x5460 with multiplier x9.5

520x9.5 = 4.940mhz real

@Xevipiu I appreciate your contributions to the forum, but you should try to address the other members in a more respectful way.

That said, as I mentioned above, my motherboard is no longer a P5B Deluxe, but a P5K with the P35. If the problem is not the chipset, what could it be?

[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

@xevipiu

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.

Regards.

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...

[Sylver]

@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]

[cobito]

@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.
