Have you got iGPU enabled/disabled?
Have you also updated all drivers and BIOS?
Also out of interest what OS are you running?
1708 BIOS is recommended
I'm not sure I fully agree.
What if he has a corrupt BIOS - factory corrupt (things like that do happen) - meaning any OC he is trying to do screws the system up, and thus can't cope with any sort of OC?
If he were to flash the latest BIOS, even re-flashing it (I would even say - force flashing it) then I would deem that as the best way to eliminate "BIOS is faulty" type problems.
-Got to stock
-Ensure it is stable
-Force flash (via USB) the BIOS -> latest 1708 one
Thank you for the response mate. im using windows 7 ultimate 64bit OS and HDMI cable for my tv.
yes, before trying to OC i make sure that all drivers and Bios are updated, i got the habit of making everything clear and ready before doing something tho this time i think i screwed up a bit
i read a lot of forums about OC'ng but i think my knowledge isn't enough. I update my Bios using a flash drive, follow every instruction and wait for it to finish. Reboot and again, test everything for stability and everything went ok.
before trying to OC i first make sure that all of my hardware/components are stable, i run IBT, prime 95, memtest85, check cpuid using cpu-z. All are working properly on stock.

Also if it corrupt, we don't know how bad it is & if it also effect the update program, it might cause bad flash. This is why I said it is bad idea. If SpEaKeRb0xXx does reset CMOS prior flashing BIOS then the "procedure" is correct or proper IMO hence reducing the risk of bad flash. Furthermore without resetting CMOS, the remnant from previous BIOS settings can cause false-positive, making user into thinking it is indeed the BIOS is corrupt even though it actually not. (The last line show I'm agreeing with you on clear CMOS before flashing BIOS.)
The other reason why it is bad idea, especially for this case, when SpEaKeRb0xXx got RAM error, SpEaKeRb0xXx reduced the RAM voltage instead of increasing it. The right course of action is to "fixed" the settings by increasing the voltage. Flashing BIOS should be the last thing you can try when troubleshooting.
It is good idea to exercise caution when flashing BIOS. The flashback button doesn't guarantee you can bring back bricked motherboard. There's already few cases it unable to recover corrupted BIOS. When this happen the only way to recover is by programming the BIOS chip using hardware programming tool or buy replacement chip (with BIOS pre-flashed).
Thank you for clearing things up!
actually i never think that flashing fresh Bios is a bad idea esp. if your system tells you that your old Bios is the problem.. Like what ive said before after rebooting or even hard resetting, board LED lights for CPU, RAM, and GPU lights up except for LED light near the chipset which is for the bios (correct me if im wrong), so that's my reason to think that there's a problem with my bios that lead me to flash a fresh one. I also think that flashing a fresh one will reset back all the values to stock which is what happen after i flash it.
But, yeah, i miss alot of troubleshooting things that i should have done first before doing what should have been my last resort.. my bad..
i have done few troubleshooting things so ill just write here what i have missed.First
, i should have turn off the system first, disconnect the plug, let the POWER LED go off, wait for at least 10 secs, reconnect the plug and power it on. this will actually give me the black screen where it says "Press F1 to configure and direct me to BIOS" if my OC configuration fails.Second
, i should have use the jumper first if the first one doesn't resolve the problem. This will reset all the values to stock. Its like Flashing a fresh Bios without any risk of corrupting your system, so this is 100% safe and most likely will resolve any problem regarding fail OC configuration.Third
, If everything else fails, last resort is flash a new bios.. But again, i can see no problem if you'll go directly in flashing a new one except for it got a bit of risk corrupting your system... So rule of thumb is start with safest to safer, if everything else fail. Then do the last resort.

I can see where you are coming from though
Of course flashing the BIOS should be an operation done carefully - but nowadays, it is kind of impossible to "brick" a motherboard,e specially when you got a means of flashing a BIOS via a USB key.
Long story short:
Flashing the latest bios, and flashing it via USB, should be his first course of action, before trying to OC.
In my case, before starting to OC, I should have tested the stability of STOCK - I didn't and thus "lost" 1 month worth of trial and error around my OC, when I found out that in fact it was a physically bad DIMM that was making my OC fail.
What I'm trying to say is this:
Let him eliminate any hardware problems, and software problems, at stock, before contemplating his OC.
If indeed he finds there is still problems, then he can RMA/return a component.
OC'ing 101 - 2 golden things I've learnt: (I'm not directing this at you or anyone):
-Determine your system is fully stable at stock
-The higher OC you go, the higher voltage you should add - this applies to RAM and CPU, and heck even GPU.
You are correct mate, the only reason you will have a corrupted bios using the safest method is if you download a corrupted BIos file, flashing got interrupted, Failing Board battery, defective flash drive or if you try to flash it with system ON (haven't tried it, i don't know if you will receive a warning if you do that). If you will solve all the risk involve, then i can say that this is the safest way to flash BIOS.I manage to solve the problem.
You and Kizwan are correct and thanks to both of you
, RAM voltage is the culprit. Im Using G.skills Sniper RAM 1600mhz classified as 1.25v
i actually use the stock voltage which is 1.25v while my CPU is at 4.2ghz. it doesn't supply enough load to boot to bios or even post something on my screen. Its like booting up without RAM installed. So i just input 1.5v for DRAM and everything works just fine. I pass IBT 8hrs Stable at 4.2ghz with 1.22v full load with temp max at 68c. As much as i want to go up to 4.5ghz i can't because my CPU can reach 92c in less than 20secs.. Im an asian and our temperature here is quite a bit high like 32c to 34c. So i guess ill just stay below 70c just to be safe. and i think 4.2ghz is already a decent OC.
