[SOLVED] Missing pin ryzen

[Zaraki24]

Hello guys!! Recently I bought a new Ryzen 3900x , Aorus X570 Elite and 2x8 go Ram GSkill 3200.
I installed the stock cooling system and then after some days I decided to change it and replace with Corsair H115i . Now...doing this the stock cooling system were attached to the cpu. Some of pins were bent and after One of them broke. Mount cpu in the socket and pc finally turn on . The only problem was with the 2 ram’s . The b1 and b2 doesn’t work . I mean if I install both ram in a2 and b2 all rgb light turn on but bios didn’t read the ram in the b2. I try to replace and install the second in the a2 and it works. So ram are ok ...why bios read me only one slot and CPUid say that I have 16 gb dual channel ?

Appears, that broken cpu pin is responsible for connecting ram modules to cpu memory controller. Because of this some ram slots are inoperable now.
Warranty doesn't cover cpu pin damage.
So you're left with options -

use ram in working slots and have dual channel mode unavailable or​

pay for a new cpu.​

It isn't working correctly because you have a broken pin on your cpu.

Now aside from buying a new cpu, if you have the pin that broke off, I would talk to someone who does cell phone soldering repair. They might be able to solder the pin back on.

The pin jump off from the cpu when I turned it to inspect . So I don’t know where he is . The pin is too small

I don’t know the option are : use the ram 2x8 on slot a1 a2 without dual channel . Ora use only 1 slot...the other is buy a new 3900

Before star windows on the monitor there is this message “memory pmu training error at socket 0 channel 0 dimm 1”

Man, this is why i like Intel bcause The Pin are not in the CPU 😬

Mmm so I can not weld the pin ?

Nope, just easy to bend tabs in the socket.

Probably I will try to buy an another ryzen to verify if the problem is cpu or am4 socket on mB

Its certainly the CPU, you broke a pin off of the CPU, as stated your only options are really to buy another one, or use the working RAM slots. I don't see how it would be an issue with the socket, the pins are located on the CPU and you specified it was an issue with pins being bent/broken.

Its easier to break motherboards pins and CPU bent pins can be fixed but not motherboards pins. I had a new 300-400$ Asus Hero 4770K motherboard which I threw in the garbage because the bent pins were not fixable, they need to be in a precise shape with a precise pressure to work. I easily fixed my Ryzen 1800X bent pins with a razor, 0 issues for over a year and all my RAMs are detected. Broken pins are not fixable though and the 3900X is an expensive CPU.

Its 100% the CPU. I had the same issue with a bent pin that I fixed and now all my RAM is working. If you had broken a pin responsble for USB, PCIE 4x or a dummy pin you wouldn't have issues.

I am curious if you can break a dummy, useless, pin and solder it on the one that's broken. Another user here had a dummy pin broken and he had no issues, I will find his thread if your willing to solder it. Also you can break off a pin from an old AMD CPU which is even better and safer.

idk why moderators have locked that specific thread but the user did not test if all the RAM was working and he marked the question as solved.

There’s no way to know if the broken pin is a “dummy pin”?

If you could manage to find the missing pin (or perhaps a suitable replacement off an old processor), then inserting that pin into the proper hole in the motherboard socket and just having it press against the CPU has been known to work in some cases. It doesn't necessarily need to be soldered to the processor, as just making proper electrical contact without touching any neighboring pins is likely to be enough. Actually soldering the pin back in place would likely be pretty tricky without the proper equipment and experience with soldering tiny things.

Probably worth asking, did you make sure the other bent pins were straightened before inserting the processor back into the socket? If not, it could be one of those other pins causing the problem.

I don't work at AMD so can't know what's each pin function but your pin is different from the other user. You can always use the 3900X as a 2nd PC for the kids, wife or as an HTPC. It will just not have dual-channel. It will still run fast as I had a Ryzen 1300X with a single 8Gb and it was fast enough.

Not 100% true. Unless the a LGA pin was broken off I have fixed multiple bent LGA pins on boards. A lot actually. And they all worked fine.

Both methods are sound but I do prefer the pins on the motherboard and I like Intels latching system as the latch goes over the CPU itself which prevents issues like this where the heatsink is tightly connected to the IHS of the CPU. I have pulled out many AMD CPUs with the heatsink even if the latch is closed.

how ?? So u are telling than can be fixed ?

In your case? No. Broken pins are near impossible to fix. You will need a new CPU.

Ok thank u so much.. tanks To all

It's difficult but not impossible. I managed to solder 2 pins and fix my R7 2700.

There is a way to have a map ?? Just to see if my pin is useless

Thats why I said near. The skill required to do it is not a common one and one false step or if he happens to miss a drop of solder that now joins two pins together and causes his board to catch fire (I have seen similar issues and when a board catches fire it goes up fast) is very high.
