I recently overclocked it to 4.3ghz and started out at 1.14v and went up by .01 each time it blue screened due power failure. I reached 1.29v and it still blue screened. I figured the blue screens are due to voltage issues. The blue screens are quite random sometimes a day to a day and a half goes by without one. Hoping someone can help me troubleshoot this issue!

using bluescreenview to copy and paste this last blue screen error i received

I have heard of people getting their 4690k to 4.7 -
4.8 stable with same motherboard granted that's probably a godly cpu but I judging by what most people are able to achieve I feel like 4.3 should be fairly easy. I was able to get 4.2 on my 4670k and z87a motherboard. I have also since lowered the multiplier and it's still having same issues at 4.2 ghz.
 
Is there anything else I can try before swapping cpus out? I have my 4670k still in my spare pc that I could try out but I feel I haven't exhausted all options in terms of troubleshooting the issue. Are these blue screens happening due to the voltage? Also what would cause the motherboard to have a limit?
 
On my 4690k, I have it watercooled, delidded, and at 1.35v to hit 4.8ghz. If I decrease voltage, or increase temps it fails. The maximum recommended voltage is 1.35. Have you increased your cache voltage and clock? That might help, I run it at 4.1ghz and 1.2ish volts. Also, what speed is your memory? Sometimes higher speeds put too much load on the IMC when the CPU is also overclocked. To fix your OC, I would put your memory at 1600mhz, increase your core voltage to 1.35, change the vrm settings to give it more power (default it's 81w, the vrms need to provide about 150w at 4.8ghz), set your cache to 4ghz, and increase the voltage by .1 for the cache.
 
So I have determined that it was an issue with the memory. The memory passes memtest with no errors however when I run the two identical Dual channel kits (ripjaw x 8gb 1600 cl9 2x4) I get the recurring bsods fairly random and a lot of the time over night. Pretty much most nights.

If I run with only 1 set installed I have no issues
