|In the future, I suggest you stay away from Intel boards. You would have been better off getting a board made by one of the major aftermarket board manufacturers (ASUS, Gigabyte, MSI, etc.). That way you'd have much better control over the BIOS settings. Regardless, make sure you manually configure the memory settings in the BIOS, do NOT use AUTO. Also, make sure you have the latest BIOS version (2006).|
For best performance with Core 2 systems, the FSB/DRAM ratio should be 1:1. Since you have a QX9770 @ 1600MHz FSB, the RAM speed should ideally run at 1600MHz. Your system will be taking a slight performance hit by running it at 1333MHz. And apparently the board's performance isn't all that great to begin with. From the trusted review site:
"We were disappointed that the DX48BT2 didn't make full use of our 1,600MHz memory but it's the low performance that would make us nervous about recommending this motherboard."
Here's some info from your motherboard manual:
• All DDR3 1600 MHz memory recommended for use on this board is based on the XMP format. See the following website for tested XMP modules:
• If you are using DDR3 1600 MHz DIMMs, it is recommended that you only
populate two of the four DIMM slots, specifically one slot in each channel. It is recommended that you populate slot 1 of each channel (black connectors).
• The maximum system memory for DDR3 1600 is 2 GB using 1 Gbit technology memory in a 1R x 8 configuration (single-sided modules).
• Remove the video card in the Primary PCI Express x16 connector before installing
or upgrading memory to avoid interference with the memory retention mechanism.
