My system wont boot up after going to BIOS. What happen is. I try to OC my system to 4.5ghz, what i did is, i set the frequency to 100, all cores to 45, Phase Control to Exteme, CPU Current Capability to 140%, then everything is in auto. It boot up, i manage to hit 4.5ghz and it says that it is stable using intel burn test on my first run, but decided to lower it down because im hitting 90c on full load. So i did run the auto tuner so i can verify upto what certain point i can OC my system. It run at 4.2ghz but only 1.3mhz on RAM, it is on 103.0 CPU frequency and 42 on cores. Its a bit slow compared to my stock RAM speed w/c 1600mhz. So i set the RAM frequency (MANUAL) to 1600mhz+, i forgot the exact value but it is more than 1600mhz (coz i dont see 1600mhz on choices so i chose the closest value), then i set its voltage to 1.30. It boot up, so i did run intel burn test. I got this UNSTABLE error on the 4th stage. I reboot my system so i can go back to BIOS but my system wont boot up. LED lights for RAM and CPU are just blinking repeatedly. So i use MEM Ok button of the board and the system boot up on black screen where is says i need to press F1 for SET UP. So i did and im now on BIOS. I lower down RAM voltage to 1.2500 and restart. The same issue occur, LED lights of RAM and CPU are just blinking repeatedly. So i turn off the computer, re seat the MEMORY and power it on. It does boot up but got stuck on Windows logo. I reboot it again to BIOS and set everything to default (hit F5), reset and everything is working perfectly. It boot up to windows, no issue, rerun IBT, check the temp, check CPUID, evrything is in stock and working perfectly.. I reboot again the system just to verify that it is working perfectly and it does. So i decided to give it another try, i reboot again to Bios, Set the CPU frequency to 100, set the cores to 42 so i can get 4.2ghz on CPU and 1600mhz for RAM with 1.25v., Control Phase to Extreme, CPU Current Capability to 140%. press f10, save and reset.. And the same issue occur but this time, only the RAM LED are blinking, i press the MEM OK button and it boot up on black screen again and it says MEM OK is successful, i continue to BIOS then reset the system without doing anything and then,,, nothing happens it wont boot up, i hard reset my computer and still it wont boot up, fans are working but no display on my screen.. I observe the LED lights on the board and everything lights up once except LED of BIOS.. I think that the BIOS might be corrupted so i flash it using a flash drive with the latest bios put it at the back of the board and press BiOS flash button. It does boot up but then again with this RAM LED Issue. I then again press the MEM OK button, go to BIOS set up, set everything to default and once again, my system is working perfectly...SHORT STORY:
after trial and error OC'ng my system, it wont boot up except on stock/default configuration on BIOS. everytime i try to configure it to OC, it wont boot up. It happen when i configure my RAM to 1600mhz+ with 1.3v. my previous attemps was OK (booting up) except for it is not stable. But after my last attempt, the system wont totally boot up if configured to OC.
I haven't tried resetting my board or removing the battery coz i think it wont help but ill give it a try. Any of you guys had the same experience?any advice will be much appreciated! thanks!
