**Edit: So I was moving up in small increments (see overclock log below) and I moved up to 3.54ghz and now it won't go into my BIOS. When I start the computer and press F2 on the BIOS screen there are 2 more loading screens before it goes into BIOS (just how my startup is).. and it freezes on that second screen right before BIOS. Now.. the weird thing is that on the first screen it's the "Enter RAID BIOS" or whatever where the RAID options are... and I can get into that (but it doesn't help because I can't change anything important) I really don't know what to do I feel like I'm going to puke!

I tried removing the CMOS battery on the motherboard for an hour, put it back in... did not reset. I tried taking the jumper out and starting the computer with the BIOS recovery file on both CD and USB drive but when I take the Jumper out for some reason the monitor will not turn on. When I put the Jumper back in the monitor turns on but it freezes at the same point it did before (right before entering BIOS)

Intel D975XBX2 Motherboard
Intel QX6800 Processor


Here is the BIOS recovery site, I don't know how to do it blind though

Feel free to point out any missteps, tips or concerns

This is my log for how I'm overclocking my QX6800

CPU Voltage (1.40v to 1.425v)
FSB (1.25 to 1.40)
MCH ICH Voltage Override (1.525 to 1.640)
Host Clock Frequency (2.66 to 2.90Mhz)
Enhanced Power Slope (Disabled)
Processor Multiplier (11 to 12)

Beginning:

Stock: 2.93GHZ

Changed Processor Multiplier (11 to 12) [Outcome>]
3.19GHZ Idle: Cores 30-34C, Load: 44-48C

Changed Host Clock Frequency (2.66Mhz to 2.75Mhz) Changed MCH ICH Voltage Override (1.525 to 1.540) [Outcome >]

3.24GHZ Idle: Cores 32-36C, Load: 47-52C

Changed Host Clock Frequency (2.75 to 2.80MHZ) Changed MCH ICH Voltage Override (1.540 to 1.545) Changed FSB (1.250 to 1.30) [Outcome>]

3.36GHZ Idle: Cores 36-39C, Load: 49-54C

Changed Host Clock Frequency (2.80Mhz to 2.85mhz) Changed FSB (1.30 to 1.35) [Outcome>]

3.42Ghz (Blue screen error on Startup)

Changed Host Clock Frequency (2.85 to 2.83) Changed CPU Voltage (1.40 to 1.4125) Changed MCH ICH (1.60 to 1.625) [Outcome>]

3.39GHZ Idle: Cores 36-40C, Load 50-55C

Changed Host Clock Frequency (2.83 to 2.85) Changed CPU Voltage (1.4125 to 1.420v) Changed MCH ICH (1.625 to 1.640) Changed FSB (1.350 to 1.375) [Outcome>]

3.42GHZ Idle: Cores 36-40C, Load 50-56C

Changed Host Clock Frequency (2.85 to 2.90) Changed FSB (1.375 to 1.40) Changed MCH ICH (1.640 to 1.645) Changed CPU Voltage (1.420 to 1.435v) [Outcome>]

3.50Ghz Idle: Cores 37-42C, Load 53-59C

Welp... FML then

Can't believe there is no onboard reset button for BIOS

Most clear CMOS jumpers only clear the CMOS when they're jumping across pins. For example, if normal is pins 1-2 jumped, then jumping pins 2-3 should be the "clear" setting. Removing the jumper won't work as the jumper needs to toggle the voltage on the "clear" pin of the BIOS EEPROM chip to work.

You also need to make sure the computer is completely unplugged from the wall for the removing the button battery method to work. If you have the computer plugged in, the board is still getting +3.3 VSB (standby power) and keeps the CMOS information in the EEPROM chip. If you have a big PSU, then you may have enough charge in the capacitors to provide the tiny trickle on +3.3 VSB to keep the CMOS information alive for some time even after the PSU is unplugged from the wall. If your board has power LEDs, note how they stay lit for some time after the PSU is unplugged. Pushing the power switch to try to turn off the computer with the power cord unplugged should get rid of that charge quickly.

Ok thank you so much I will try the other pin and yes I have the power chord unplugged while I do these things. So... unplug everything, put the jumper on the other 2 pins for awhile? Do I plug the computer back in once I have it set on the other 2 pins or no?

*Edit: Ok for now I unplugged everything and have the Jumper sitting on the other Pin

Now put the jumper back on the original pins and then turn your computer back on. That should reset the BIOS.

According to the Intel how to, it should be able to be done blind. It looks like it is all automated.
February 8, 2010 4:23:07 PM

I tried it automated, I just booted up and let it run for 10 minutes (when it should take less than 5), but this did not change the settings. I've only been able to get into BIOS on one occasion (10 minutes) ago on a normal boot up (I thought I was SAVED!) and I quickly tried resetting the CPU override options back to normal but it froze in BIOS and then went back to freezing on Bootup. Going to try putting the pins back now

I wonder what was different that it let me into BIOS for 5 seconds.. ugh the headache.
February 8, 2010 4:25:55 PM

I put the pins back to normal it's still freezing on bootup. Should I leave the pins on the other 2 longer? Should I plug the power in after I put it on the other pins so it knows to reset?

Thank Jesus Christ Allah Buddha I was able to get my room cold enough to where it would go into BIOS. I quickly changed the Host Clock Frequency down a few notches and exited as fast as I could. Wow........... unbelievably happy. Thanks everyone for helping.
