RAM running at slower speed after bending CPU pins

[erik999]

Specs :
CPU : Ryzen 7 2700x
Mobo : Strix B450-f Gaming
Ram : Corsair Vengeance RGB Pro 3200mhz CL16 (Samsung)
GPU : Asus rtx 3060 TI dual


I recently bought an AIO for my R7 2700x, while removing my stock Wraith prism cooler I noticed it wouldn't come out even though the latches were off, the thermal paste provided had "glued" itself together so my CPU and the cooler was stuck together. I thought it was just hard to get off so when i pulled it out the CPU came with the cooler. 3 pins were bent in the process but i straightened them carefully. I got the system running again but quickly realised my RAM was only running at 2133 mhz. I have tried D.O.C.P(X.M.P.) and manually overclocking the RAM but i either get BSOD or it won't post. with D.O.C.P. enabled it just runs at 2133mhz. Could this be due to the pins being bent and should i just get a new CPU? If not could the motherboard be broken?

P.S : The RAM ran at 3200mhz just fine before switching the cooler.

IMPORTANT NOTE : I tested the RAM slots and A1 and B1 does not even post with D.O.C.P, meanwhile A2 and B2 boots and shows 2133Mhz.

Also i flashed BIOS and installed the latest Chipset drivers a day before.

Unfortunately you may have damaged the socket so its no longer making good contact to some pins.  That's really bad luck if so.

 

Also depending how bent they were, I've have situations where when putting the CPU back in they bend again if you aren't careful in letting it drops into the socket, brute force is not your friend with these things which many of us learnt the hard way.

 

Hindsight and all, but stuck paste is easily solved by slightly twisting the heatsink rather than brute force.

Alright, Is the better move to buy a new CPU first or MOBO first? What i was originally thinking was that the bent pins might have been related to the memory controller.

Yup I did this a few months ago because I was in a hurry and wasn't thinking. It ended up having no damage thankfully. Another tip alongside slightly twisting the heat sink is letting the cpu heat up a bit. Warm paste lets the heatsink come off SO much easier.

Very hard to say, I mean how bent were they and how close to their original shape did you manage to make them?

 

I'd certainly tend to blame the motherboard if the pins look relatively straight again.

When you did your upgrade, did it cause the CMOS to be reset? The reason I ask is that the pins might just be a red herring and the problem is that the board is not reproducing your original settings. One thing I would check straight away is that when you enable XMP/DOCP the BIOS is correctly setting the DRAM voltage, because some boards do not do this and that results in immediate BSODs or no post.

I don't have your manual to hand, but probably normal. Usually you need to use slot 2 and slot 4 (numbered from the CPU, left to right).

Nothing strange with Zen+ not running 3200 RAM.

When you apply xmp, lower the frequency to 2666 and I believe it will work.

It did not automatically do a CMOS reset, I did manually via the CLRTC pins.

Thanks, I will try that. Though it would be strange if that is the case since it ran 3200mhz prior to this incident.

Atleast one of the pins were bent to the point where it was almost touching another pin. I did manage to get them relatively straight though.

thats true,  both my msi b350 and b550 set the voltage to 1.35, but my bdies wont post at 1.35 with xmp or oc, it needs to be 1.36! lol...

no, its very strange when you said it ran before, but you can try 2933, a lot of Ryzen magically run at this number...

 

 

 

As for the real issue,  i would buy a new mobo first, its likely you broke something during "the operation", then a new cpu if that doesn't help.

I had the same problem with you when I upgraded my Ryzen CPU.
The cooler was stuck to the CPU.
So I had that bright idea to heat up the thermal paste...by running a CPU benchmark on Windows.
So while the benchmark was running I pulled the cooler really hard (in hindsight I should had twist it instead) and the cooler came off with the CPU and the Windows crashed...typical.

I don't know if my CPU was damaged, because I just put the new one afterwards, but the Motherboard was fine.
