Hello!
Problem summary:
I have a problem with my BIOS. The motherboard lowers the memory
frequency after the power has been unplugged. The problem does not
occur when the system has been shut down and started while the power
has been plugged. I have tried changing the battery but it didn't
help. I think I have found a bug in the F10 version of the BIOS and it may
also be present in version F8.
System configuration:
Motherboard: GA-EX58-UD4P rev 1.0
BIOS version: F10
Processor: Intel Core i7 920 2.66 GHz
Memory: OCZ DDR3 1600 MHz 3 x 2GB (OCZ3P1600LV6GK, CL 7-7-7-24, DRAM
voltage 1.64 V)
Graphics card: Sapphire Radeon HD4870 1GB GDDR5
Operating system: Windows Vista 64-bit SP1
Power supply: Corsair 650W
Detailed problem description:
When using optimized defaults, the memory frequency defaults to 1066
MHz, TRAS to 16 and DRAM voltage to 1.5 V. After manually changing
memory settings to the recommended settings, i.e. frequency 1600 MHz,
TRAS 24 and DRAM voltage 1.64 V (actually 1.65 V), system boots fine
if the power has not been unplugged between shutdown and startup but
if system is booting when the power has been unplugged the motherboard
states "Bios recovered after overclocking / voltage adjustments" and
the memory frequency is set back to 1066 MHz. The problem occurs in
version F10 of the BIOS (I have tried F10d and F10h). I don't remember
if it happened in F8 but now I have reverted to F7 and the problem is
gone.
Please verify if this is a bug and if it will be fixed in the final
version of F10.

Mattias
