Note
1. 28-LANE CPUs can only support up to 3-Way SLI™/ 3-Way CrossFireX™
2. The PCIE_X8_4 slot shares bandwidth with M.2 x 4.
40-LANE CPU: The PCIeX8_4 slot can only be used in x4 mode or lower when used simultaneously with the M.2 connector. If x8 mode is used, the two connectors will be mutually exclusive.
28-LANE CPU: The PCIE_X8_4 slot will be disabled and the M.2 connector will always be enabled.
3. The PCIE_X4_1 (gray) slot shares bandwidth with the PCIE_X1_1 slot, USB3_E910 and SATAExpress_E1 connector. When the PCIE_X4_1 slot is occupied by an X1 or X2 device, the SATAEXPRESS_E1 will be disabled. When the PCIE_X4_1 slot is occupied by X4 device, the SATAEXPRESS_E1, USB3_E910 ports, and the PCIE_X1_1 slot will be disabled.
4. Due to chipset behavior, the SATA6G_78, SATA6G_910 ports do not support IRST including RAID configuration.
5. These functions will work depending on the CPU installed.
6. These SATA ports share bandwidth with the PCIE_X4_1 slot, and when the PCIE_X4_1 slot is ocuupied, the SATA ports will be disabled. These SATA ports are for data hard drives only. ATAPI devices are not supported.
7. 2 x USB2.0 port at mid-board shares with ROG extension (ROG_EXT) port.
8. USB3_E910 ports at back panel will be disabled when the PCIE_X4_1 slot is occupied by an X4 bandwidth device.
9. Extreme Mode capabilities, including V1, V2, DRAM and other voltage definitions, vary by chipset. Please refer to your motherboard manual for details.
10. One 5.25" drive bay is required for NORMAL Mode installation.

We have the usual LN2 Mode Jumper and Slow mode switch as seen below.
What’s new are the Safe Mode Button and the Retry button.
Both these buttons function very similarly, once pressed, the system would immediately shutdown and power on by itself.

The difference is that
- Safe Mode button would power up the system in Safe mode
- Retry button powers up according to the settings set in the BIOS.

Both do not clear the settings you have saved in your BIOS.
Traditonal way to enter safe mode is by pressing the power button for 4 seconds
When you finally want to give up trying to boot at a certain setting, the Safe mode does it for you without you having to waste time pressing the power button for 4 seconds.

The retry button lets you retry booting at tough to boot settings. An example is getting a hang at post code ‘bf’ when trying to boot with tough Memory settings.
A lucky boot will get you to boot successfully so pressing the retry button here can save you time in getting a post.
It can also save you time at a processor hard lock whereby the reset button gives no response.

#77

- The Safe mode button saves you time and triggers a shutdown and bootup in Safe mode when you give up trying to boot at certain settings.
- CPUZ opens up pretty slowly, so use realtemp to check the actual cpu frequency
- When a heavy load such as PhysX/CPU test comes and the system shuts down and powers up by itself, this is due to the OCP on the PSU being triggered with a high transient load. You will need to change out a PSU or lower the load line so that CPU input voltage droops when the load comes.
- Sometimes a certain DRAM Frequency is just tough to boot due to clock and RTL combination, and going higher actually boots up fine, so try higher as well.
- When Pushing Single Stick of DRAM, the best slot to use would be Channel A red slot, the red slot most left.
- When just focused on maxing out BCLK, you can try low CPU Input voltage like 1.65v and match it with 1.85v PLL Termination voltage.
- Note that 13x~17x Core and Cache Ratios are buggy and can be unstable to don’t use those ratios.
- You may find Game Tests and Physics Test liking different temperatures on the CPU, maybe -95~100C for GT, as cold as possible for PT. So while PT is loading, set Pause ON with OC Panel, pull CPU down to colder temps and unpause.
- The best overclocking DRAM Ratios are the 2400 ratio and below most of the time. The Higher Ratios may not work as well.
- For Win XP, Disable Speedstep in the BIOS to get the Turbo Ratios to work.
- A lot of times, booting up too cold (say -130C), the CPU trips out and you’re stuck at 12x CPU Ratio in the OS. You will have to warm up and you will see the ratio come back to normal.
