Asus P6T Deluxe V2 manual 51

2.CPU / DRAM Bus / QPI DRAM overvoltage setting (3-pin OV_CPU, 3-pin OV_DRAM_BUS, 3-pin OV_QPI_DRAM)

These jumpers allow you to enable or disable the advanced CPU, DRAM Bus, and QPI DRAM overvoltage settings in BIOS. Read the following information before you change the jumper settings.

		OV_CPU	OV_DRAM_BUS	OV_QPI_DRAM
Pins 1-2	(Default)	up to 1.70V	up to 1.90V	up to 1.70V
Pins 2-3	(OV Enabled)	up to 2.10V	up to 2.46V	up to 1.90V

•Before you change the jumper settings for extra-high overvoltage ability, use the BIOS items first to adjust the desired CPU, DRAM, and QPI performance. Make sure your system functions well under the highest BIOS voltage settings before you change the setting of these three jumpers.

•DO NOT set the OV_CPU jumper to pins 2–3 when you install a new CPU and have not booted for the first time. Doing so may cause the system to halt. For system failure due to the wrong setting of the OV_CPU jumper, shut down the computer and move the cap back to pins 1–2.

•According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage requirement below 1.65V.

•The system may need a better cooling system (for example, a water- cooling system) to work stably under high voltage settings.
