New Intel i9 developed faulty cores, anyone else have this?

Even if you have to pay asus for repairs it is not too bad. Depends on the board if worth it tho. Mine was about $130 with a destroyed socket, and they sent me a new complete kit in return. As for stability some chips are weird. Mine really hates anything other than LLC3.

@PoisenJam. I would definitely start with the bracket if you are using one. Notorious for weird core/mem issues. Gotta go real easy when tightening those down. Barely snug

It certainly could be the contact frame. I am using the first gen one with the 0.06Nm torque spec. I actually used a torque wrench too... But that is extremely low torque and could probably loosen from the type of moving and shaking one does when trying to work out all the air pockets in a custom loop! Thankfully, I have the newer TG contact frame now. Seems more fool-proof and much more secure.

Given the uncertainty, just seems sensibler to disable the core and wait until RMA is approved. And if I tear down the loop I may as well upgrade, especially since I can't be without my system during the RMA process. I also wouldn't feel right about selling my used 13900KS if there was a chance it was faulty.
