CustomPC says they have confirmation from ASUS that Intel is warning against running your DIMM voltage higher than 1.65v on Core i7 boards. While this isn't a big deal for most people, it could limit the type of memory you run and adversely impact overclockers that push their DIMM voltage to the limits when overclocking.

The warning was revealed when XFastest published some photos of the retail-packaged Asus X58-based P6T Deluxe motherboard. In the photos, the DIMM slots are covered by a sticker (pictured) reading: 'According to Intel CPU spec, DIMMs with voltage setting over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage setting below 1.65V.' Of course, this is still beyond the standard JEDEC DDR3 voltage spec of 1.5V, but it's also a long way off the voltage required by overclockers' enthusiast memory, such as Corsair's Dominator TW3X2G2133C9DF, which needs 2V to run at its specified 2,133MHz maximum speed with timings of 9-9-9-24.

Asus' PR rep, Iain Bristow, confirmed to Custom PC that the sticker had been placed on the motherboard after Intel's recommendation, saying 'it is recommended that you should not use voltage higher than 1.65V.' However, he added that 'if an end user does decide to use memory with a higher voltage, they should be aware of the risks,' so it looks as though Asus won't be restricting the DIMM voltage in the motherboard's BIOS.
