|If you have damaged your mboard by overclocking it, you're on your own - the mboard's warranty does not cover that. |
Depending on the e8400 cpu model, the minimum specific bios version required is either 0506 or 1003
The numbers on the left are the Intel part number.
If you click on blue highlighted ones, the Sxxx model is shown there.
The Intel part number and/or the Sxxxx model of the e8400 cpu you installed must be on the list.
If your present specific bios version is not high enough to suppport recognizing the cpu you installed, the mboard may not boot properly.
In that case, you need to install a cpu your present bios version already supports properly, and flash the bios to the newest non-beta specific bios version.
Load bios defaults in the mboard's bios Setup after you have flashed the bios, to make sure the contents of the Cmos part of the bios match the changed bios version - flashing the bios usually DOES NOT do that automatically - the bios may not work properly unless you load bios defaults after you flash.
Where is the present bios version shown ?
It might be
- shown on the first screen or on one of the first screens you see when you boot the computer, but that may be obscured by the Asus logo screen - you can often disable the logo screen from popping up by changing a setting in the bios Setup, or by de-slecting Quick boot or similar.
- it may be shown in the bios Setup
- it may be shown in System Information, under Bios Version/Date, on the right side of the first screen you see
(e.g. Start - Run - type: msinfo 32, click OK or press Enter)
Some ram manufacturer's modules do not strictly adhere to the JEDEC standards that most mboards bioses use to determine ram settings.
In that case, the ram settings in the bios Setup that the bios has automatically chosen may not be correct.
Check the ram settings in your bios - the ram voltage, and the ram timing numbers - those should be the same as for the specs for the modules themselves. Often the ram voltage and timing numbers are printed on the label on the modules.
If the voltage setting or timings settings in the bios are different from the specs for the ram, change them in the bios. The timing numbers must be as close as you can get to the same, or slower timings (higher numbers = slower) - you won't notice the difference the slower settings make.
If you have a mix of different modules
- don't mix ram that different voltages arespecified for - the bios will force the ram to use the lowest voltage, if "by spd" or similar is used (default settings) - ram that a higher voltage is specified for is more likely to not work properly in that situation.
- the bios settings must be those for the slowest timing settings of all the modules, or slower (higher numbers = slower).
