The motherboard and RAM vendors have been advised by Intel to take up X58+Core i7 combo and to follow a strict memory voltage limit of 1.65 volts limit as not doing so can lead to killing of the CPU, informed Inquirer. 

The news has come in light after when several pictures of the new ASUS P6T Deluxe motherboard was posted on net, and the motherboard had a big warning sticker on it that anything more than 1.65 V will destroy the CPU. When ASUS was confirmed about the fact, it said that it’s all true. 

Though this does not seem to be a big problem, since DDR3 JEDEC specs instructs it to be used at 1.5 volts, but overlockers will face a problem with performance memory because many memory vendors provide faster RAM kits, which function at higher voltage levels. 

Following this, Mushkin, in order to meet the specifications of the X58/Core i7 combo, would re-design their kit, which will be out by next month. However, there have been no comments from other memory vendors, other than that their kits are pending certification. 

There has no clarifications from Intel’s side as to why would memory voltage damage the CPU, but it is being guessed that the reason behind this has got to do something with the on-die(integrated) memory controller of the Nehalem. The X58/Core i7 combo has not yet reached the Indian market, but let us suggest that people importing it should also get a compatible RAM kit, since if they fail to do so, they might have to underlock it.
