Should i change my cpu ?

[Rylox]

I bought yesterday my new cpu ( i7 4790k ) to replace my old intel pentium g3258 which i had for over a year. Everything was fine once i installed the new one but then i did something stupid. I opened Intel extreme tuning and clocked there my cores to x45 ( 4.5 Ghz ) and the cache. After that my pc shut down. It was able to boot the Bios but couldnt run Windows 10.

I tried to reset the Bios and even took the battery on the mobo out and put it in again. After that i still couldnt boot Windows ( everytime turned the pc i saw a small A2 in the corner and the screen signal turned on and off all time ). I took it then out of the socket and installed it again. Everything seemed fine and I´m using it right now .

I ran a lot of benchmarks ( Userbenchmark , Cpu-Z , Intel 64-Bit Diagnostic tool and Geekbench 32 bit ) with normal ( about 1-2 % difference to the references) results. I´m playing witcher 3 with High settings and have stable 33-40 fps. The temps are between 20-25 ° C (Idle) and 40-60 ° C (when playing witcher 3 ) .


I have now 3 questions

1. Should i sent it back ( i still have 12 days time to do it ) and get a new one.
2. How can i check if everything is ok ?
3. Would it be safe to try to OC it again , but this time through the BIOS and with instructions.


My Rig :

CPU : Intel core i7 4790k
GPU : Nvidia GTX 760 MSI OC Twinfrozr 2GB
RAM : HyperX 8GB dual channel 1866 mhz
Mobo : MSI z97s krait edition
SSD : OZC Vector 180 120gb
HDD : WD Blue 1 TB
PSU : XFX TS 550 550 W
Cooler : Corsair H100i GTX


Thank you for any answers and sorry the bad english 😀

Overclocking voids the warrenty in nearly all cases, it should be fine but if you wanted to you'd be best to keep an eye on it's temperature as if it's too hot or very cold there's an issue. You can overclock again but only do it in small increments, you can change the voltage as well but I stess that you be careful with it and go up in minute amounts as it is liable to fry the CPU. Best of luck!

It takes more than what you did to fry a processor. It's fine. No need to commit warranty fraud

It sounds like you need to do a lot more research before you try overclocking again.
