What do I have to do - specifically - to get this mobo to read my RAM speeds properly?
It already said 1066 FSB in the CPU section of the BIOS.
Since this has been explained several times, you're going to get the abbreviated version. Look back through the thread for a more thorough explanation.
The mem is not being improperly detected. At 266 FSB (1066 effective) memory must also run at 266 (533 effective - dual data rate) to avoid using a memory dividier. The board has simply clocked your mem to in sync with the FSB. If you raise the mem to 400 (DDR2-800) the 2:3 FSB:MEM divider will be used.
To change the mem frequency in BIOS:
Advanced/Jumperfree
- set AI Overclock to Manual
- set DRAM Freq. to DDR2-800
- set VDIMM to rated voltage for your mem. It's probable 2.0v or 2.1v for your kit.
To set memory timings in BIOS:
Advanced/Chipset
-set SPD Timings to disabled
- set the first 4 values accordingly (not the names of each value as the BIOS order may not match the order listed by the manufacturer)
