Abit AW9D memory keeps resetting to slower speed on power off

T

Tank

System is a Abit AW9D board, Core 2 6400 cpu, 1 gig OCZ 6400 gold kit, Hiper
Type R 580, Radeon X1900XTX graphics.
The system is water cooled . When I power on the system the settings for
the memory, fan control, voltages reset to failsafe mode.
If I reboott the computer and enter the BIOS and set the memory to the
correct settings and I disable the CPU fan beep the computer runs fine.
I can reboot the computer as many times as I want and everything is fine as
long as I don't switch off the power supply. As soon as I do this then
switch it back on and reboot, the memory goes back to fail safe settings
( 667 1.8 volts instead of 800 2.1 volts) and the fan control
beeper starts beeping again. As I use water cooling, the cpu fan is not
needed. When working, all voltages, temps are fine and computer is rock
stable with the
memory running at correct speed/ratio to the cpu. I have installed a new
cmos battery just in case. When the memory and fan settings change to the
fail safe mode no other setting is reset in the BIOS. Any help appreciated

cheers

I wonder if that's part of the throttling function...if so a pseudo CPU fan
at the connector may stop it.

That's what I was thinking. I'd probably plug a case fan into the CPU fan
connector. :)

Yeah I was going to mention the case fan thing, however a watercooler dude
wants -not- to 'hear' of 'fans'.

Actually, even if you water-cool, you still need cooling fans (though you
need fewer of them). That is, unless you are going to be running all your
components outside of a case, just sitting on a benchtop or something. Heat
still builds up in a case, and passive cooling is not enough, as it will
only protect major components like CPU, GPU, etc (whatever has a waterblock
attached). As a minimum, you would need at least one cooling fan pushing
cooler air into the case. If you get a 3-pin style, you could hook that up
as a CPU fan to keep the BIOS happy. :) -Dave

Last year's version of the AW9D m'board did not support dual-core.
Memory specs on the two versions of the board are unknown to me.
