CPU and Motherboard have non-compatible LGA 1151

[nontechnicalwight]

I got an ASRock Z370 Killer motherboard, and was going to get an i7-8800k. However I could not find any at the time and instead elected to buy an i7-7700k. I saw they both used LGA 1151 sockets so I thought that would be fine, although I now know that is not the case. Unfortunately, I placed the CPU in the motherboard and closed the clamp. The CPU slid in easily and the clamp closed with just a bit of effort (I've never built a computer before so I don't know if that is abnormal, but I closed it with one finger). As soon as it closed, I saw the warning that my motherboard did not support Intel's 7th gen CPUs. I then took the CPU back out immediately.

Obviously this was a bad move. Now I will either need a new CPU, motherboard, or both. I looked at both the CPU and the motherboard and neither of them had any obviously bent pins, but I don't completely know what to look for. I have read that the physical dimensions of the sockets for 7th and 8th gen are the same, is there any chance either the CPU or motherboard are not broken?

Even though the 7700k a 7th gen cpu, has the close to the same 1151 socket. It will not work on a 300 chipset motherboard. Also the 8700k an 8th gen cpu will not work on a 200 chipset mb. You should have done your homework before making this purchase.

I personally would return the cpu and opt for the 8700k, which I would have done if I could have afforded it. Instead I got the i5 8600k and it is bad ass.

Oh and there is no 8800k it is the 8700k,. Perhaps that is why you could not find it.
