My system is an (overclocked) ASUS P6T Deluxe with an Intel i7-920 processor. I have been running the following BIOS settings with 6GB (6x1GB) of Corsair Dominator DDR3-1600 memory (2 TR3X3G1600C8D 3x1GB kits) with no problems. However, I want to upgrade to 12GB of Crucial Ballistix Tactical DDR3-1600 (3x4GB BLT3KIT4G3D1608DT2TXOB Kit). I assume the only necessary BIOS changes will be reducing DRAM voltage to 1.50 and (possibly) changing the DRAM Timing Mode to 1N.
Can anyone confirm this assumption or let me know if I should make any other changes?
-CPU Ratio Setting 20
-Intel Speed Step Enabled
-BCLK Frequency 180
-PCIE Frequency 100
-DRAM Frequency DDR3-1443MHz
-UCLK Frequency Auto
-QPI Link Data Rate Auto
-CPU Voltage 1.225
-CPU PLL Voltage Auto
-QPI/DRAM Core Voltage 1.20
-DRAM Voltage 1.60 -> 1.50
-DRAM Timing Mode 2N -> 1N (?)
-All other BIOS settings are Auto/Default

Thank you for your message. I have had a look in to this model for you. It can support 24GB in total over 6 memory slots and BLT3KIT4G3D1608DT2TXOB will be compatible. BLT3KIT4G3D1608DT2TXOB is actually 1.5v memory so you don't actually have to change the voltage at all. To get the best performance, we would recommend change the memory profile to XMP in your BIOS.
You can buy that kit against that system here: http://www.crucial.com/usa/en/p6t-deluxe/CT2587173
We do also have a great guides and installation section on our website. You can see that here: http://www.crucial.com/usa/en/support-memory
If you do have any other questions at all, please don't hesitate to ask.

I tried X.M.P.
The X.M.P profile made the following changes to my original O.C. setings:
-CPU Ratio Setting 20 -> AUTO
-Intel Turbo Mode Enabled (On "Manual" Turbo Mode is not available)
-BCLK Frequency 180 -> 133
-DRAM Frequency DDR3-1443MHz -> DDR3-1600MHz
-QPI/DRAM Core Voltage 1.20 -> 1.35
-DRAM Voltage 1.60 -> 1.66
How can I retian oy O.C. settings (CPU Ratio and BCLK) and get the memory to 1600MHz? When I tried, once again, only 1443MHz was available.
