Succefully booted into windows using iGPU. Done some research and I can say maybe this problem is quite familiar with heavy & big GPU and no solution for the time being ?

Regardless of that, will try back flashing it tomorrow. Thanks Kevin

Try to boot with iGPU (without VGA)

Remove any sound card/LAN etc.

Try backflash BIOS method.

1. Download the latest BIOS from Asus website.
2. Format a USB pendrive to FAT32.
3. Extract the BIOS file and rename the file to M5F.CAP.
4. Put the BIOS file on your USB pendrive.
5. Shutdown your system.
6. Connect the USB pendrive to the white USB port.
7. Press the USB BIOS Flashback button/ROG Connect button for three seconds till the LED begins to blink, then release.
8. Wait till the LED stops blinking.
9. Power on your system using the Start button.

Seems I still getting the B2 error, can't help it with new BIOS as well. Shud be my PCIE slot faulty or GPU faulty?

I guess I need so help here. I tried to delid my 3570k and it is consider a success but unfortunately my ram no longer working in dual channel. Could it be I have damaged the imc ? And just wondering how do u all apply TIM on the die? Just a small pea size or?

I think you need to reseat the CPU. Either tighten or loosen it a little bit.

Hmm do u mind to elaborate more on tightening the CPU? Are u meaning tighten the heat sink ? The closest memory bank to the CPU is not working whenever I tried to put my ram on it. Does it means that I have damaged the imc?

tighten the heatsink or waterblock. Check CPU socket for bent pins. Try other mobo or cooler.
If single module of  RAM put on the problematic DIMM slot is undetected then might be you have a damaged chip.

Hmm, then I guess my cpu is damaged. Prepare to get a new one. Any idea how to get Costa Rica chips? Buy from new egg?

I dont know your place but nearby here there are Costa Rica chips avallable.

U r in pg right. May I know where or any forumers here is selling Costa Rica chips?

Hi guys. Im new in OC. I using Z77x-D3H with 3770K. I want to overclock at 4.5Ghz and running 24/7. May I know what is the optimum voltage?
I tried 1.3V but blue screen pop up. and now running at 1.315V stable. I did some research and some forumer say they can achieve 4.5Ghz at 1.2V. really? How they do that? I go a really good WC set but my temperature still go up to 90C when running prime 95. Any1 can help me? Or 1.315V and 90C is fine?

Your chip might be a dud. Every chip is different so there's no such optimum voltage. TJMax is 105C so you are still fine.

thats mean Im unlucky? ==
I built 2 rigs at same time and I now got the other running sabertooth motherboard. with better WC set. I OC it to 4.5Ghz and set it to 1.300V but my comp not responding in few seconds and I was force to restart. So I got 2 lausy 3770K? ==

May I ask, Im using asus AI suite2 to overclock. I set the voltage at 1.25V but why Aida64 show me my CPU voltage is 1.3xx when I running stress test? I tot I should fix at 1.25V as I set?

That must be due to higher level Load-line Calibration (LLC) which is causing vdrop under load.
