I have a p6t deluxe v2 board and i7 920 with my ocz gold 1600mhz DDR3 memory. how can i get it to 1600mhz? I am limited to 800mhz and 1066mhz.
 
You could raise your memory manually to 1600 but the reason people put 1600 memory in a 1066 system is for overclocking. Using DDR 1600 lets you maintain the default memory clock of 8 as you raise BCLK all the way to 200.

133 BCLK x 20 CPU Mult = 2.66 GHz
133 BCLK x 8 Memory Mult = 1066 MHz

150 BCLK x 20 CPU Mult = 3.00
150 BCLK x 8 Memory Mult = 1200

167 BCLK x 20 CPU Mult = 3.33
167 BCLK x 8 Memory Mult = 1333

183 BCLK x 20 CPU Mult = 3.67
183 BCLK x 8 Memory Mult = 1467

200 BCLK x 20 CPU Mult = 4.00
200 BCLK x 8 Memory Mult = 1600

just up the memory multiplier to 12 so 12*133=1600 and the uncore to 24

On the P6t you should just be able to manually choose the speed of the ram without worrying about the multiplier. The BIOS only gives you certain choices are representative of certain multipliers.
