i broke my CPU...maybe?

[Guarino]

hi everyone, i owned a 4790k cooled by and NH-D15 for over a year now, and lacking time i never overclocked it. some days ago i found the time to overclock and test the system stability. Reached the 4.8 Ghz mark, with 1.29v, validated with 9 hours of AIDA stability test, with temperature averaging mid 80 °C, with really rare spikes around the 90 on only 2 cores. Thought the overclock was stable i fired a rendering on premiere, and started watching netflix while i was waiting and...it crashed. Entered the BIOS, gave him a tad more voltage (1.3V) and did the same thing, rendering while eatching netflix aaaaand, crashed again. The system freezed and i had to force reboot. Tired to deal with overclock at that point, i dialed the stock bios settings and booted the system, and once the render was finished i went to sleep. The next day had a fake boot, with a BIOS screen prompting the boot failed with the applied settings. Now it seems i get that message every time i shut down the computer and power it on again after some time, but when the system boot, everything seems to work and stable.

 

It is my first time dealing with overclocks on the CPU. Anyone know how to figure it out?

Air coolers are not good for overclocking

you are wrong here. The NH-D15 will beat most 240mm AIO's out there. Check your facts and know your hardware before making uninformed posts like this.

Oh wait what? Who told you that?

What are the specs for your system? I would be hesitant with those temps. I run AMD, and that's way to high even to my own standards. What are the temps for everything else?

Try and do a reset on your BIOS. Take and shut of your PSU and pull its power then pull the battery on your board for about 10s and then seat it back in and try booting.

Nonsense, big air coolers like the NH-D15 are good for overclocking.

I had my FX 6350 OC to 4.5 Ghz on a Coolmaster Hyper D92. It can be done. But even with that small cooler and my CPU, I still never got temps like that.

Set your bios back into defaults and then save.

i already did that on the screen prompting the failed boot. and sometimes it still fails

Gigabyte z97x Gaming 5 board, 1050W PRO Black Edition PSU from xfx, NH-D15 cooler. The temperature on the rendering was roaming around low and high 60s, those temps were only seen on a full fledge stress test.

yeah in fact i was not concerned about that. On the 4790k, and any other non extreme cpus since ivy bridge if i'm not wrong, every cooler is severely bottlenecked by the crappy TIM between the die and the IHS

Remove battery, unplug cord, wait half hour then put battery back in. Still the same, then your CMOS battery might need to be replaced.

i don't really think a bad CMOS battery can make a boot on stock settings to fail. Also i found the possibility for the battery to be replaced really remote. I bought the MoBo less that 2 years ago, and CMOS battery can last a long time.

 

Edit: and in any case, if the battery is defective, i should get a reset of the BIOS settings every time i unplug the power cord...which i am not

If the battery is plugged in still, the BIOS settings will remain, thats its function and sole purpose. Thus why I recommended you remove the battery for 10s after the machine is powered fully down and you remove the power cord from the PSU.

It's possibility your CMOS battery is running low to begin with and it's a coincidence it happened to fail when you were playing with your cpu.

[Guarino]

anyway, i took the battery off for around 2 hours. A screen Prompet the BIOS reset, i've loaded the "optimized" settings and rebooted...first boot succeded without problems. i'll keep the computer on for some hour, to charge the battery a lil bit to avoid some problems. What should i do if the problem begin represents?
