2700x - snapped pin, ghetto repair and a lapjob!

Mussels · Sep 22, 2020

Short version: I couldnt solder the loose pin, i just dont have the right tools. I got annoyed at that RAM issue and just moved the 2700x and a new make believe pin over to my entry level B450 board, so i have working reliable dual channel RAM and PBO.

The x370 and 1600 can live together as friends

Thats what happened with this weird pin loss initially.

Reminds me of this Linus video, and his attempt at soldering pins to a Ryzen 3700X.

You don't have the right tool, but all users do have a tool that can solder. It's in the kitchen it's call a stove, cooker whatever..

Anyway place the pin on the solder pad & gently move CPU into the oven, grill & monitor the temperature. Solder should melt at around 220c. Do not place the CPU to near the top if you put it in a grill, oven. The flame may burn the PCB, so placing the CPU on lower shelf maybe better. At any point do not disturb the CPU until it has fully cooled down, as all the other soldered pins would have melted too.

I do some of my soldering this way when everybody in my household is out. Remember your not supposed to mix soldering fumes & food together, so i give the cooker internals a good clean before anyone returns.

Yea... I'd just follow the professional repairman like Rossman. Warm the whole part to around 95C... have your fine tip solder iron ready.. put a dab of lead free solder on your broken pin and with the solder still melted, drop it on the pad. There's a reason they have a thing called warming plates. You can use a pizza stone if you have one too.

Yes, you can find many things around the house to preheat the CPU before putting a soldering iron to it. You just have to be carful that you don't burn yourself. Clothes iron for example is effectively a hot plate.

Look again in the left panel it clearly shows 7.9GB in the right panel it includes the 8GB of page/swap file so reads 16GB

Seems to be working fine in the B450 board, i'd rather have it working reliably there even if its a cheaper board... at least that board can run newer CPU's

leo_rcm · Sep 26, 2020

Well... i have admit... first time i saw this post i thought "this guy is messing with all saying he put the thing to work just doing that".

Long story short.... I LOVE YOU Mussels.

The pc is booting now. All i dis was put the wire there.

Its still missing the pin.. i will try to get one from old athllon cpu i have and solder it. Fuck it...

The pins for Socket AM4 are smaller in diameter, and length.

I just saw that! Btw... you're right about the audio... it does not work. So it is true that you can run the cpu without a pin if the missing pin is "not that important". I cant instal the audio driver from the motherboard. But i can use an soundboard or use the audio from the gpu though.

I cleaned the missing pad to try the solder but as you said the pins are a bit different... here's a photo.

Ps: i watched a video from jayztwocents on youtube that he fix bended pins with a razor blade. I did the same here and i end up scretching the cpu surface. So... be carefull with that video, guys.

Mussels · Sep 27, 2020

When i tried to solder a pin, i fucked it up and removed a 2nd one.

There are now two pieces of wire keeping my 2700x running, but hey its working fine!

Important trick is the length, too long and they bend and dont make contact anymore... i went maybe 1mm longer than the existing pins this time around

The Foldinator · Sep 27, 2020

nice work there..

Gotta love fixing CPU pins when like shaking Stevie . :oops:

had to fix a X58 Skt 1366 bent Pin(s) but the satisfaction when it boots up again :peace:

Calmmo · Sep 27, 2020

I managed to bend a pin on my 3900x recently, removed it from the system to change the mobo, cleaned the paste, left it on the desk, forgot I put it there and while moving some objects i managed to (thankfully) just barely hit it while placing something else on the desk. 1 pin (corner edge) bent inwards a bit, it was easy enough to fix, but I... uh it sure gave me a scare!

I am planning to burn the solder iron and then pu in the top of the pin... i hope it will be enougth to melt the solder with some paste. I will update you guys.
