Xeon E5472 problem on P5B Deluxe

[cobito]

@Sylver The problem is that I'm not sure if the fault is with the pin. If I start messing around with soldering, I'd be putting all my eggs in one basket for something that might not be related. I'm not even sure if the OC of the e6600 is the cause of this.

This motherboard has served me well and for a long time. It dying wouldn't be a great tragedy, but I don't want it to die in such a miserable way. Let it be because a mosfet pops due to lack of ventilation, because a capacitor bursts, because the soldering on the chipset comes loose... but not because I've fried a damn pin on the socket; not like that!

But let's see, if the plaque has really exploded (which is not certain), then notice what elegance it has had.
For next time, get the cheapest one, add a matching font and turn it upside down, and you'll have your Nit del foc guaranteed... ¡i visca València!

Are you sure it's the plaque?

[cobito]

@whoololon I'm not sure. Looking at the socket's feature sheet, the damaged pin is labeled BCLK1 which seems to be an input clock signal that defines the FSB speed. The issue here is that I'm using the PC right now to write this message. If that pin were really damaged, it wouldn't work (or maybe it does and that's why I can't OC it?). It's probably more likely that it's not making good contact with the Xeon.

Or maybe the pin isn't the problem. The truth is, I don't know.

use silver conductive paint. and yes. that pin 5 is necessary. erase all the processor contacts with an eraser and that damaged pin. use a needle to lift it up a little and apply some conductive paint.

[cobito]

@JuezDred ok, I'll keep that in mind. In the end I'm going to leave it for late summer because I'm going to need my pc operational for the summer and I don't want to take a risk.

I have a can of silver paint from when I used to do bridges on my athlonxp but I suppose it will already be in bad condition.

I just realized that we have the same Xeon, and in terms of performance/price right now it's one of the top for reusing 775 boards.

My specific problem is that on a P5KPL-AM EPU it works well at its 3.00 Ghz, with the FSB at 1600 and all, but as soon as I increase it a little bit of frequency (not even 50 mhz more), the board stops detecting the SATA ports... And I don't remember if I did the test, but I think the IDE ones too. I think that the slightest OC causes a failure in the chipset, although despite everything it boots, but it doesn't detect any disk and therefore can't start any S.O.

Mention that I have added the microcodes to the BIOS, updated also to the latest version.

Right now I have it running at 3.00 Ghz, but the interesting thing about this micro is that you can overclock it, so if anyone comes up with something...

PD: Coincidentally, this board of mine also has a messed up socket pin, it's a hassle to disassemble it now, but if I remember correctly it was one of this area that I point out here:

I remember that it was hitting with one of the bands. Anyway, it's the same thing, everything works perfectly below stock frequency and at stock frequency, but as soon as I increase a little bit of frequency, to hell with the disk drives.

Saludos!

What a waste of money, look at that, buy yourself an E5420

Very good those constructive comments Xevipiu (leaving aside that they said 5472 not 5420).
Beer and pedals

[Xevipiu]

Let's do a theoretical class, the crap about the x5472 is that it's capped at x7.5 400x7.5 = 3Ghz), which is equivalent to an L5420/E5420 at x7.5 (333x7.5 = 2.5Ghz)

The higher the multiplier, the more air you give to the 775 board because of its FSBwall

The best investment is an x5470 at x10 or the cheap x5460 at x9.5 for 18€

I've already had a few beers, that's why I'm blind!



[Sylver]

All of that is true, with the small difference that the X5472 has a 1600 bus stock, which for 13€ is little less than a gift.

¡Saludos!

[Xevipiu]

An E5420 costs €5
An x5460 x10 costs €16

Intel Xeon X5460 3.16GHz 12M 1333 Processor close to LGA775 Core 2 Quad Q9650 CPU

Does it have native support for Strapp400? All Core2Quad can run at Strapp400/1600, the limitation of dividers comes according to the chipset used, the important thing in these cases is to have a high multiplier, especially in this case that wants to use it under an i965 and its limitations with these 45nm.

Well, I got a practically unused Asus P5K from a PC that was going to be thrown away. Although it is from a lower range than my P5B Deluxe, it has a more modern chipset and what is more important: it has the socket intact.

So in the coming days I will get to work on the subject to see how much I can get out of the Xeon. The only problem remains the frequency limitation of the memories (DDR2-800).

[amd125]

I am very happy about the new motherboard. I really regret selling the 775 platform years ago, because I had it with a Q6600 at 3.2 and it went very well, but only having 4 Gigas of RAM made me jump to an FX 8320 that broke... and from the RMA I received an FX 8350.

Although I was able to tinker with it, I changed it for a 2600K some time later. Well I changed it... I have had the FX in the closet for more than half a year.

Good luck with the Xeon and long life to the 775

[cobito]

Well I've managed to get it working and for some reason, the micro has reached its native 3GHz with DDR2-800 memory when with the P5B Deluxe it didn't go above 2GHz. I suppose it's because of the support for the 1600Mhz that the P5B didn't have.

The thing is that at 3GHz the system is not stable. Wndows gives a blue screen while booting and in Linux, if a kernel panic doesn't jump at startup, the desktop environment doesn't finish booting. I've lowered the frequency to 2.4GHz and it's perfect, but of course I'm wasting that 20%.

By the way, the BIOS is updated and the micro patch is added. Do you know if something can be done to squeeze out the 3GHz?

Thanks.

@cobito ¿Qué fuente montas?

I think it's a matter of the FSB. That chipset reaches a maximum of 1333 mhz according to the manufacturer, so theoretically anything you put above that 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 one mhz more than the native 3Ghz of 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...

Greetings!

[cobito]

@sylver That makes sense to what I have experienced. I have tested by setting the FBS to 333, 340, 350... and from 350 the problems start. I left it at 333 so I could put the memories at 800MHz. In the end I am left with a micro similar to my E6600 series with double the cores and double the cache, which is not bad but it is also not the panacea since little software makes use of more than 2 cores (I have realized that not even games).

Anyway, let's see if they lower the RAM, SSD and graphics cards at once and I retire this pile of junk already.

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

[Xevipiu]

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
