Is this broken pin essential to CPU functioning?

[TechiGamer]

Hi,

One of my motherboards has a partially broken pin, and has about 3/4 the normal length of a pin. However, I have read, that if that particular pin happens to not be essential for the functioning of the CPU, then the motherboard may still be used.
After digging around, I found this datasheet from Intel, and on page 112, you can find the pin diagram of the LGA 1150 socket.

https://www-ssl.intel.com/content/dam/www/public/us/en/documents/datasheets/4th-gen-core-family-desktop-vol-1-datasheet.pdf

Based on that information, I found that this broken pin is "B18" which is DDID_TXDN3. Does anyone know if this pin is required ,or is it covered for by other pins?

I tried googling, but found no relevant information.

*Edit, in the same document on page 90, I found the description of this type of pin.

Description:
"Digital Display Interface Transmit Differential Pair"

Would this affect video output only?


Thanks!

i dont know about that specific pin but i have found MANY pins are not essential to operation. the most common issue is a dead ram channel. and 3/4 length might still make contact

Ya I was thinking the same as well. Its not completely broken off, and maybe I could bend it upward a little more to increase the chances of making contact.
Also, I'm not sure how much the cpu and pins are compressed when you install the cpu. If the pin and cpu are squished due to the pressure plate, then it would likely touch.
But still, I would rest easy knowing that the pin is not absolutely necessary.

I'm not sure if you noticed, but I just updated my post, as I have found what the pins function is. Do you know what its function is, knowing that extra information?

my best guess is intigrated grapics however the cpu does compress the pins quite abit when its in the socket

As cdabc123 surmises, it's related to the integrated graphics - it's one of the communication lines used to send data to a digital display panel. If you don't use the integrated graphics, it should be fine. If you do, it may still be fine anyway - the specific transmit pair affected may not be used or the pin may still make contact, given how much they squash down when you clamp the CPU into the socket.

Thanks for the replies!
As I was going to take a picture of the pin to post on this thread, I actually noticed, when I zoomed in, the top part of the pin wasn't broken off, contrary to what I had suspected, but rather it was bent back. With my unaided eye, it looked as if it was broken off.

I tried to bend it back, and this is the best I could do:

Will this work?

Also, what is the tolerance for the positioning of the pin? So, how much can a pin deviate from its standard position (left, right, up, down) before it causes a short circuit or other problems?

that should work and i cant answer tolerance because their are some many factors
