Hi and thanks for replying,
I read in the instructions for the 975XBX that you need to move the jumper over one pin, then startup the machine with a bootable bios disc in the floppy drive, my machine doenst want to boot form floppy. and i keep hearing booting ht emachien with the pin moved can be bad.
maybe just removing the battery is the way to go if i dont want to/can't use a floppy to get the bios back?
OK. Take a deep breath and let it out slowly (count to ten). Relax. You are going to be one happy moth**f***er when you get your system working and you will. You've got a great board and a great CPU.
Power down you don't need to unplug, just be powered down.
You need to locate the BIOS jumper. With the CPU on your right look straight down on the board. You will see a "coin" style battery socket just to the right of the SATA sockets and behind and to the left of the IDE ribbon cable connector (which on this board is turned to the side instead of pointing straight up). About 1.5" to the right, and right behind the right side of that IDE connector you will see the BIOS jmper. It is a 3-pin strap.
Normal connection is on the two pins to the right with pin on the left showing as bare copper.
OK. Move the jumper to the two pins on the left so that the pin all the way to the right is exposed.
Power up. This will force the system into default settings and your system will start to POST and you do not need to hit F2 because with the jumper on the left it will automatically go into BIOS setup!!! How cool is that?
Now. Go to advanced chipset and answer yes to to continue. Set Host Burn Mode to Postive. Set Host Burn Mode Percentage to highest setting which will be 30. Set PCI and PCI-Express to Default. Set the two voltage overrides for MCH and FSB to one below max (you don't need max).
Hit ESC. Now go to memory menu and take it out of automatic to manual.
We're going to run you memory 1:1, OK? Its good.
Choose 533 instead of 800. I know it sounds slower but you are going to take the Bus speed from 266 to 345 in one click, so trust me, its OK.
Set the memory for 5-5-5-15 and set the voltage for 2.2V
Now. Hit F10 and save. You'll get a message to power down and move the jumper back. Do that.
OK now power up and you'll come up at around 3.10GHz when you check your speed in Windows.
At this point you'll be going *much* faster than a $1200 E6800 Extreme chip and it will feel creamy smooth.
At this point you can reboot and go into BIOS normally, but if you lock it tight just use the technique we discuused with the jumper.
If you want to know how to access the advanced "OC Debug" overclock menu just post back and let me know.
Have fun with your superfine system. The Bad Axe didn't get that name for nothing, bro. It is a stable board with a beefy voltage section.
