Ddr2 1066 showing no option for 1066 in bios?

Just installed 2 2Mb sticks of G.Skill F2-8500CL5D-4GBPI-B DDR2 1066. Having troubles getting Windows 7 64 to recognize it as such. CPU-Z shows it as pc2-6400 800. I go into bios and 1066 isn't even listed as an option. tried setting it to 533 but am unable to find where or how to switch to T2. any help in this regard would be appreciated.

  2. Solved...
    4 x DIMM, Max. 8 GB, DDR2 1066/800/667 ECC,Non-ECC,Un-buffered Memory
    Dual Channel memory architecture
    *Due to AMD CPU limitation, DDR2 1066 is supported by AM2+ CPU for one DIMM per channel only.
    **Refer to or user manual for Memory QVL (Qualify Vendor List)
    ***When installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.

    You can set the memory to DDR2-800 4-4-4-12 2.0V and it should perform just as well. This way you can take advantage of the performance memory you purchased. If you do not manually make the adjustments, it will default to 5-5-5-15 timings.

    CPU-Z Max Bandwidth shows DDR2-800 (400MHz) because that is the max any memory can automatically default to with AUTO settings. The JEDEC (memory) standard for DDR2 is DDR2-800 CL5. This will be the same for any DDR2, but it has no affect to actual performance. The memory's actual rated specifications are shown in the furthest right column of the timings table. It is on the same page/tab, just towards the bottom.

    Thank you
