with the purchase of a qualifying Intel processor SSD or knck you could
0:10
instantly win an Intel gaming Jersey and be entered in the draw for the ultimate
0:14
system click now to learn more welcome to a bit of an impromptu late night Vlog
0:19
I've got a COR i7 something k whatever the point is
0:24
it's an LGA 2011 chip here that is perfectly good but unfortunately isn't
0:29
booting in this x79 Delux ASUS board and
0:34
it's not the fault of the board somehow at some point I hope you guys can see it
0:40
here but right there there is a bent pin
0:44
now the advantage to LGA chips is that
0:47
the CPUs themselves are much less fragile than they used to be but back
0:51
when pins were on the bottom of CPUs or on AMD CPUs where they still are it was
0:56
a lot easier to repair them and you could even use little tricks like
1:00
uh putting the St of the pin or even another piece of metal into a socket and
1:04
as long as it would make contact a lot of the time you could get your CPU working again well LGA 2011 repair is a
1:11
lot trickier so we're going to give it a
1:15
shot here let's see how much I can zoom in and show you guys that damaged spot
1:19
right in the middle of the frame there there's one pin that's either broken or
1:23
bent it's hard for me to even tell so I've got my tools handy here first up is
1:29
a standard pin or needle you're going to want one that's reasonably fine okay I
1:35
got a pink one second is you're going to want some kind of a magnifying glass so
1:40
you can actually see what you're doing and then third is you are going to want
1:46
an excellent light source so in my case I'll be going with an iPhone propped up
1:52
between the PCI SL e slots so here we go now the way these
1:57
pins work is they're kind of like little Springs so uh here you can see that they
2:03
actually have a flat portion let me just see if I can even get in
2:08
there they have kind of a flat portion here at the bottom and then they end in
2:12
a little ball at the end now it looks like what's happened to our pin here
2:16
after closer examination with the magnifying glass is the ball on the end
2:21
has broken off but that doesn't mean that it's necessarily done for we may be
2:26
able to bend the pin back into to a
2:30
position where the rest of it so not the pad at the end but the rest of it the
2:34
stump of it can make contact with the pad on the bottom of the CPU so that's
2:38
going to be our goal here so what we're going to do is we're going to use very
2:41
delicately this pin being careful not to damage the ones around it mind you if we
2:45
do it's a dead board already um although I think ASUS can do socket repair for a
2:50
fee but this is an engineering sample board so there's no warranty so uh we're
2:53
just going to kind of go for the Gusto here and we're going to try to bend that
2:58
pin into such a position that it can make
3:02
contact with its corresponding pad on the bottom of the CPU
3:06
here so I think I got it by uh cuz the
3:11
the pin has a couple of kinks in it so it kind of goes this way and then back
3:16
and then up to the head so what I did was because we're missing the head now
3:20
is I I bent it up and then I bent this
3:24
one up a little bit so hopefully that stub of the pin is now in the same
3:29
position where the head would have been so it can make contact now you can see it still
3:33
looks a little funny but the only way to know for sure unfortunately is to fire
3:39
up a CPU and find out if she posts now this isn't the kind of thing that I
3:42
actually recommend doing because I have no way of guaranteeing that you wouldn't
3:46
kill your CPU by doing it but uh hey
3:49
there the line is Tech tips so we like to live
3:56
dangerously all right so it's Moment of Truth time I've gone ahead and built up
4:01
the test bench here hopefully I wired it all up correctly let's just see what
4:06
happens okay there we go so it is powering up but this was normal we
4:11
expected that let's see if we get anything on the
4:19
display no way ha got it look at
4:28
that ch 7 4930k new CPU installed it worked we got
4:34
it well uh there you go guys as uh as
4:38
ghetto as the methodology may have been that is how I go about fixing pins on
4:44
LGA sockets I've actually done it a number of times this one I had already
4:48
worked on for about uh 15 minutes before I tried it tonight but that was when I
4:53
had a much thicker pin um and I also
4:57
didn't really have a great light source I didn't have a magnifying glass so I
5:00
was able to do a bit of a better job this time and uh we've got it up and
5:04
running so that's fantastic Salvage to motherboard $300 motherboard sure beats
5:10
uh sure beats buying a new one so thanks for watching guys like this video if you
5:14
liked it dislike it if you disliked it leave a comment and let me know what
