 Topic: Incorrect CPU installPosted: 21 Nov 2016 at 8:33am |

Hello I would like to ask if an incorrect cpu install would utterly destory a mother board?
I did install this cpu into this mother board incorrectly. ASRock ASRock Fatal1ty Gaming E3V5 Performance Gaming/OC LGA 1151 Intel C232 SAT This mother board was bought brand new but the cpu was installed in the wrong direction. Cpu was uninstalled and correctly reinstalled and the Motherboard worked despite the previous error and pc functioned, windows 7 was installed. Full Spike Protection Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard?™s components from being damaged by these unexpected voltage spikes. Cpu removed and Mother board was removed from pc because of bent pins. I have corrected the bent pins as best I can and pins seem to be uniform once again.
Thank you for any thought concerning this. |

"Utterly destroy a mother board" is a rather specific statement. IMO, an utterly destroyed mother board will not function whatsoever, meaning do nothing when you try to start the PC. Your PC seemed to work after you installed the CPU correctly. Given your post, it seems you then discovered bent pins, which I assume is in the CPU socket, which you fixed. Or did that happen before you installed Windows? I'm confused regarding the sequence of events. If the PC seems to be working now, you're fine. You may not have tested every last function of the board yet. An incorrectly mounted CPU could have many potential outcomes. If the CPU did not fall into the socket itself, it would not have touched any pins in the socket. But attempting to mount the CPU cooler is the point where the CPU should have been noticed to be in the wrong position. Only you know what happened, and all the details we have are some of the CPU socket pins were damaged, apparently. Also, what is the point of including the description of Full Spike Protection? Is that your hope for the board being protected from the improper CPU installation? |

The resistors on the bottom of the CPU will bend pins if the CPU is inserted incorrectly, but you already know this.
In addition to checking for bent pins you should also check the CPU itself, if you latched the retention bracket you may well have also warped the CPU. The CPU socket has a notch that lines up with a cut corner on the CPU, installing the CPU in the wrong orientation will cause the corner over the notch to bend. I had a client that did the same thing with a new build and not only were there bent pins but one of the corners of their CPU was also bent up. In this instance the motherboard was purchased used and could not be returned so I helped them out and straightened the bent pins and used a vice + block of wood to straighten the bent corner of the CPU. As far as I know the system is still working fine some 6 months or so later. Amusingly I had bent pins in my own E3V5 Performance/OC thanks to a dropped tool. I was able to straighten the pins and it now works fine. My point is, if the pins are straightened correctly there shouldn't be any problems but, and this is a big but, it is very hard to tell if ALL the pins are straightened correctly. Some of the pins being bent will not exhibit any noticeable issues but cause the CPU or other motherboard components to run at high or low voltages, PCIe lanes may be disabled, The memory controller may only allow single channel operation etc etc. The list is as long as there are functions handled within the CPU die. If the board is new and under warranty I would see about an RMA. If the RMA is refused then the best you can do is examine the socket very carefully with a magnifying glass from all possible angles to ensure the pins are aligned properly. If all looks well then put the system back together and run it through stress tests checking all the temps your board can monitor. If any of the temps read over say... 50c (other than the CPU) then there is likely still a pin or more out of place. If all is well on the temp front and there is no unstable/abnormal behavior you should be OK. The pins being in the socket with intel is both a boon and a curse, it used to be far easier to bend pins on the CPU back during FCPGA (Flip Chip Pin Grid Array) days but if you do bend pins in the socket it can be all but impossible to correct it with LGA (Land Grid Array).
