I just upgraded a Socket 775 system (No. 2 in signature) to a Gigabyte EP45-UD3P. I've been running it (Q6600) for over two days straight now at 3.2GHz. It's been completely smooth and steady running two Folding SMP (CPU) clients and two GPU clients. The problem is, every time I restart the system it throws out the BIOS settings. When I perform a restart, the fans stop, it clicks, fans restart, another click, fans stop...three boots before POST starts, at which I must enter the BIOS to restore settings. When I enter the BIOS, there is a red warning box informing that the computer unsuccessfully tried to boot to the previous settings.
The system does not do this on Fail Safe settings or default clock, 9 X 266, RAM on auto, 800MHz DDR. I flashed the BIOS to the latest non-beta release (F9) but the problem is unchanged.
Following are the settings I'm using for 3.2GHz. If not shown, I've left the setting at default or "Auto":
- 8 X 400 = 3200MHz
- Performance Enhancement: Standard
- G(MCH): Auto or 333MHz
- System Memory Multiplier: 2.00B -- the (G)MCH + Multiplier result in an 800MHz memory speed, which is the RAM's rated speed. I also used the combination of (G)MCH 333MHz and Multiplier 2.00B for the same result of 800MHz. (no difference in performance or in the restarting problem)
- Loadline Calibration - Enable
- CPU vCore: 1.4250 (power hungry CPU, had to use this voltage with the previous motherboard as well)
- CPU Reference Voltage: 0.800
- MCH Core: 1.400 (default is 1.100)
- DRAM Voltage: 1.90 (default is 1.80)
- PCI-e Clock: 100MHz
- Memory. Apart from setting the system memory multiplier to result in 800MHz (rated speed) and boosting the voltage by 0.10, I've not altered any settings. Timings are by SPD.
It runs beautifully with these settings, full load, 24/7, it just spits them out at every restart.
What gives? Is there a better BIOS version? Do I need to remove the CMOS battery for a couple hours? Is there an important setting I borked or left out?
Need more DRAM voltage?
CMOS battery going bad? But the power to the computer is never disconnected. ??
