I recently bought a new motherboard (Gigabyte GA-G31M-ES2L) so I would be able to replace my two 1GB 800MHz memory modules with two 2GB 1066MHz ones. The motherboard says it accepts 1066MHz modules in overclocked mode.
After changing the BIOS settings, one of three things happens:
■ after the POST screen, the system freezes or
■ after the POST screen, the system reboots or
■ I get a message saying that Windows can't be started because of a hardware error.
I used the following settings (slightly overclocking the 2.50GHz E5200 CPU):
[fixed] Robust Graphics Booster [Auto]
CPU Clock Ratio [10x]
Fine CPU Clock Ratio +0.0
CPU Frequency 2.80GHz (266x10.5)
CPU Host CLock Control [Enabled]
CPU Host Frequency (Mhz) [266]
PCI Express frequency (Mhz) [Auto]
Performance Enhance [Standard]
System Memory Multipliere (SPD) [Auto]
Memory Frequency (Mhz) 800 1066
******** System Voltage Optimized ********
System Voltage Control [Auto]
x DDR2 OverVoltage Control Normal
x FSB OverVoltage Control Normal
x CPU Voltage Control Normal
x Normal CPU Vcore 1.16250V
[/fixed]
'x' indicates values which can't be changed (dependent on other settings). I also tried other multipliers, e.g. 10 (2.66GHz), but even if I UNDERclock the CPU, e.g. with a multiplier of 8 (2.13GHz), the computer won't boot. At this setting I just get a column of letter 'H's after the POST screen.
The other thing is that now one of my hard drives is making ominous clicking noises. The same thing happened with my previous system drive (160GB) after I incorrectly installed the 1066MHz memory in the board which I had at the time, which was only built for memory speeds of 667 or 800 MHz. At that time I was getting more and more sector errors all the time, and the system was just getting slower and slower each time I rebooted, until I replaced the hard drive with a newer one, as well as replacing the faster memory with the one I had previously been using. I think now it might be my second oldest drive (300GB) which is on its way out too.
What am I doing wrong? I have never done any overclocking before, so I need some advice from someone who is more experienced.
