Do these missing CPU socket pins are essential?

Long story short, my friend works at Asus and I bought a box full of customer return gaming hardware, and one of them was an Asus Maximus V gene with bent and missing cpu pins, I got an old Pentium that I didn't care about frying, dropped it in and tried booting it, the motherboard got power and it showed up q-code 76 (q-code 76 corresponds to PCH DXE initialization problem) and cpu and ram error led turned on, I took out the CPU and tried to un-bent the cpu pin that was bent, dropped in the CPU, and the CPU led no longer turns on, but the motherboard still shows q-code 76 and ram led is still on. Theres three missing cpu pins, I'm unsure how I would go about fixing them and if all three are necessary for the CPU to work, I hope someone can find a diagram and figure out what those three pins supposed to do, they're on an edge so I was thinking about stuffing a small piece of wire in there, again, I don't care about frying the CPU as it's just my testing CPU so I'm opened to various types of possible fixes. Thanks, heres a picture of the socket, it's LGA 1155.

I did get a post at the end, took an old PCIe extension cable and pulled out pins from the socket and used those pins to shove in the holes of missing pins and cut them to size, they did scratch the cpu connecting points very slightly but it's nothing major and the motherboard posted, took me about 36 hours to do this, kept cutting to wrong size, or the pins would shoot out of the pliers and I had to start again, but it's duable and it worked.

If CPU pins are missing, and you're getting CPU and RAM Q-codes, those missing pins are the problem. You don't need a diagram to see that, since missing CPU pins tend to cause lots of problems, even if only 1 is missing.

There is no reasonable way to fix them without thousands of dollars of equipment (at least to do it properly). You'd need a decent soldering station and lots of time.

Since you tinkered with the pins by hand, any warranty you did have is probably voided. You'll have to buy a new motherboard or hope ASUS is nice enough to RMA it.

I have dealt with missing cpu pins before, I know for sure some are not used and are there for future use and some are voltage controllers which will only effect overclocked CPU's, also, this motherboard is a customer return from Asus, as I said in the main thread, I never replaced a socket before so I'm not sure how it's done, but theres no contacts on the back, just contact traces. I just want to find out which pins are essentials, this way I can try fixing those that are needed just so I can get a post. Tried connecting the motherboard to my laptop via ROG connect, didn't really give me a lot of info.
