ASUS shuts down when I try to OC or TPU it.

When it comes back to POST, I have to hit F1 to get the EZ bios screen (there is a message "overclock failed"). None of the three tuning buttons in the EZ screen are selected at that point. I MUST pick the middle one (Normal), then save and exit the BIOS screen, or it just repeats the no-POST again. The posting check lights are not indicating that POST is hanging up on any component in particular.

Under normal, stock, settings, I can benchmark and torture test it for ever with zero issues. Very, very stable.

well it seems the next logical step would be to try actual overclocking and skip the whole software garbage.
need to get a few things off of auto....set your main voltages (vcore, cpu/nb, dram )to stock values, set the cpu, HT, and NB multipliers, and set your RAM speed and timings to stock. save and reboot, then start taking up the cpu multiplier a couple of notches. see if it causes the same issues.
my hope is that the software is causing problems, which isn't out of the realm of possibility with auto-OC stuff.

I will try that. Thanks for the tips on the settings. I am kind of new to OC'ing so i wanted to see where the Autotune went with it and then I would try it on my own, but I guess that's not going to happen.

I'm trying to think of the last time I had success with an Auto-tune. It would have to be back in about 2006 on an Asus P5B-Deluxe WIFI. If I remember correctly, it only went about 15-20% OC then crashed. This was on a 2.4GHz E6600, which OCed like crazy. Manually I could do something like 3.3GHz stable. Been too long to remember exactly.

It's odd that simply turning off AUTO on many settings on a board and replacing manually the stock values often works. With AUTO, there's no telling how stupid the board can be lol. I usually set them manually as a starting point.

It's not that the overclocking is lame, it's that the system simply goes dead if you try to OC anything. Even if I go into the EZ Bios screen and pick ANYTHING but the "NORMAL" mode, the board won't POST.

I think I will try pulling the RAM out and the drives out to see if I can make it POST with the slower or faster settings. I tried switching to manual and inputing the stock numbers manually in the AI tweak BIOS screen..and it runs fine, even if I increase the CPU frequency a bit.

If I manually raise the clock from 200 to 203, it will run fine but it will benchmark slower!

Either my board is faulty, I am missing something somewhere in the BIOS settings, or some components are faulty and causing the board to be lame. Power supply? really? Even if the thing won't POST with SLOWER settings, but runs great and stable with all set to stock values?

Additional Comment:

To test the manual tuning through ASUS AI software interface, I was able to increase settings.

Here as follows: With my AMD FX-8120 (3.1) and 16G of Corsair Vengeance DDR3-1600(2x8G)

CPU Bus/PEG - 204 MHz
CPU Ratio - 18 (3600MHz)

In DigiVRM:
CPU Load Line - Medium
CPU Current Capability - 120%
CPU Voltage Spread Spectrum - ON
CPU/NB Load Line Cal - HIGH
CPU/NB Current Capability - 120%
CPU Power Phase Control - Optimized

I tried Passmark on it stock, and modded:

Stock - 2146
Overclocked - 2095

??? Do I need to leave the BIOS settings on "Auto" or enter them by hand in the BIOS for "AI-manual mode" to work?

If I try to increase numbers on the actual BIOS boot screen, the PC starts hanging on POST.

My problem is that if I switch on the EPU switch or the TPU switch , the PC boots up to a black screen, shuts down, boots up with no beep and just spins the fans. I can only get out by resetting the CMOS. Is this normal?

No this is not normal activity. You can operate those switches "on the fly" while in bios even or in windows. When the TPU activates it happens on next restart.

Try updating the bios.

I may need to attempt a BIOS re-install. No matter if I use the ASUS Autotune or the AMD Overdrive-Autoclock software, the results are the same. Shutdown/reboot/no POST sequence.
