Sorry to have missed your posts!!! This thread was meant as a welcome thread, not for issues so that is why I had not looked at it until now. Sorry
Do you still need help with this? Did you ever try raising your PCIE and SB Voltages?
If you have not, try this as I have had a card or two give me issues until I raised these.
MCH Core…………….....1.100V...........: << 1.14 (1.20-1.24 if 4GB)
MCH Reference….…….0.800V...........; <<< Leave
MCH/DRAM Ref.…......0.900V...........: <<< Leave
ICH I/O……………….....1.500V............: <<< 1.58
ICH Core…………...……1.100V............: <<< 1.14-1.22
You need to change a few things in your BIOS to run 1066 ram at 1066. All 1066 ram will start at 800, and show as 6400Mhz as that is what they really are. It is up to the end user to set timings and voltages so that they run at spec 1066Mhz.
First off I see you are running single channel mode, did you know that or are you just testing one stick in the above images?
You need to adjust your system memory multiplier, since you are running 333 FSB you would need to set this to 3.20B (3.20 x 333 FSB = 1066Mhz)
Then you will also need to adjust your ram voltage manually, I'd start at 2.1V and if that fails move to 2.2V (Use a fan on the ram if you run 2.2V 24/7). That would be +0.3 for 2.1V and +0.4V for 2.2v on the DDR2 OverVoltage Control setting in the MIT Section.
