From one side, Asus with the reference to intel specification recommends to not exceed 1.65V as memory voltage, since this can lead to the damage of central processor. From other side, some enthusiasts were able to exceed the recommended voltage level without any consequences, observed over the short and long term.
As explained associate, all depends on the bios settings . In the general case intel actually does not recommend to increase the memory voltage beyond the limits of 1.5-1.65 v, since this can reduce the processor service period . If user set the memory voltage to 2.0 v without any bios settings fine adjustment , the processor can malfunction almost immediately.
Memory producers already prepare DDR- 3 complete sets , capable of working in the regimes up to DDR 3-1600 with the relatively low voltages and aggressive timing.
It is completely possible that after some setting selection (Bios) DDR3 memory modules can be safely exploited with approximately 1.7-1.8 v. According to some calculation, the integrated three-channel memory controller for bloomfield processors ensures such capacity which is sufficient to the majority of users even in the regimes DDR 3-1333 or DDR 3-1600. However, extreme overclocer will use advanced motherboard which allow to overcclock memory to more than DDR 3-2000 without the fatal consequences for the processor. Related Products :
