Hello,

I retrieved a good P5Q3 Deluxe.
Electrically seems fine, but the socket miss two pins.
One is non essential (VSS), but the other is AL6 that from datasheet is VID3.
What can I do apart from throwing it?
Is there a way to fix it or at least let her stay with a single cpu forever somehow (X5450)?

Well, the most thorough fix would be to replace the socket. Some repair shops are equipped to do this, but it may cost more than the Mainboard is worth right now.
It's something that could be done at home and the socket + expendable material would come in at about 5€, but there's a lot of equipment and knowledge involved.

I may have someone who can do the work for me. What should I buy and where?

A getto solution like a wire into the missing VID3 hole?

Sorry for my ignorance, but I am not sure what I should do.
In short, I would like to use a X5450 cpu (modded), what I need to do? Taking out other pins?
At the moment it is not posting.

Do nothing, floating VID is "1"

download https://www.chinafix.tech/asus-motherboard-p5 … -b1a-boardview/
download and install/run once https://github.com/OpenBoardView/OpenBoardVie … ases/tag/9.95.0
find obv.conf in your system, for example C:\Users\...\AppData\Roaming\OpenBoardView\obv.conf in win10
edit obv.conf to add Asus encryption key

FZKey = 0x25d8d248 0xe1502405 0x56b5d486 0x69213fe0 0xa22490ec 0x01fdd9fa 0x0681955f 0x0fac202d 0xdac9eeb4 0xf6024aba 0xcd8b4cc6 0x9f307c8e 0x4ab8fad7 0x232f967d 0x5e8666a3 0xde966d4b 0xc64bfb1c 0xea7fb092 0x1a751a7e 0x37e8f0bc 0x3359c8f3 0x969ac22b 0x610f5804 0xd99d10e6 0xc58d54d6 0x1f9aea8b 0x8e388c1a 0xe4f7d2ed 0x3e5da1f6 0xedfe818a 0x7252b016 0xb503a170 0xc4128fb6 0x2c93ceeb 0x53539a6e 0xdacf7668 0x3ab78e52 0x8ee9d815 0x7043f799 0xc6a05dcf 0x727f1da2 0x0dfd983b 0x78c53872 0x00945692

now you can open P5Q3 DELUXE 1.02,B1A.FZ
OpenBoardView loads the board reversed/mirrored, Do as Missy Elliott told you and click 'Space M R R' to flip it and reverse it.
CTRL-F and type H_VID3, click search, you will quickly find AL6
You will now discover it goes to two resistor networks, one passes it down the line to voltage regulator and Winbond monitoring/control chip, the other Pulls it UP to VTT.

TLDR: Do nothing, floating VID is "1"

Ok apart from all technical part, I still do not know which options I have.

Seems to me options are to either to

  • have the socket replaced, which is likely not economical, or
  • not replace the socket and use the board as is, which going by the info posted might just work despite the damage, or to
  • put the board into storage for the time being and hope its value goes up/cost of work goes down so the first option becomes viable.

look at http://www.pc-optimise.com/portables/pinmod/VID.png
https://www.intel.com/Assets/PDF/designguide/302356.pdf
vid3 forced 1 limits Vcore selection, look at default VID pin status of the cpu you have and check if it doesnt jump too far off

X5650 is 1366 and wont fit in this board, X5470 is perfect, but also 🤣 $50 while ancient. You can build 4770 system for similar money.

Sorry, I always confuse the 5650 with the 5450.
I am trying to use it with a x5450 (modded).
I am not a tech expert so the only thing I can do is cutting pins on cpu or socket to make it work.
If not I would try to put a wire on the missing AL6 spot.

There are techniques to replace individual pins, without replacing the whole socket. It's not something you can do yourself without skills and equipment. Look for a lab, that deals with motherboards repairs in your area.

So you dont even consider following the Do nothing advice?

Do nothing is basically equal to throw it.
It does not work anyway so, why doing nothing?

This is the first time in this thread where you even hint at trying to run it 😀 What are the symptoms? does it power the PSU at all? does teh PSU stay powered on with fans running? do keyboard LEDs blink?
What cpu did it not power up with? flip the cpu over and using https://www.intel.com/Assets/PDF/designguide/302356.pdf find its VID pins and check them with a multimeter against ground pin to determine what VID CPU requests when powered on.
this one VID pin missing has very low chance of making the board not power up, so im guessing its broken in other ways too.

The motherboard has all led on, the power button works as intended, fans spin.
No post, black screen.
Power button works to shut down also.

Tried Q9550, E7500, Xeon x5450

what led? cosmetic ones or do they mean something?

that means there is no panic, no emergency, board thinks everything is fine

ps2 keyboard led behavior is important - it tells us if bios starts executing since one of the first things BIOSes usually do after initializing CPU is initializing keyboard controller and that makes the keyboard blink

do you have a post card? a multimeter?

I am afraid I do not have postcard.
Willl send the board to a more tech savvy friend
