“Nvidia has investigated end user reports of high performance DIMM failures on the Nvidia nForce 680i SLI-based platforms. […] We believe that the observed failure is a breakdown of the silicon in the DRAM caused by the prolonged application of 2.4V on the voltage rails of the DIMMs,” Nvidia said in a statement published at EVGA’s web-site.

The company noted that failure is caused not by the nForce 680i SLI core-logic, but by tremendously increased voltage for memory modules, which cause DRAMs malfunction at any mainboard running any chipset that can handle the clock-speeds of the high-speed DIMMs.

Currently Nvidia nForce 680i SLI chipset is the only core-logic on the market that officially supports 1200MHz clock-speed for DDR2. There are not a lot of memory modules that can operate at over 1100MHz, however, one of such products is Corsair Memory’s 2GB TWIN2X2048 - 10000 C5DF kit that can operate at 1250MHz with 2.4V voltage setting. The memory module kit has received the so-called “SLI certificate” from Nvidia, which should, according to the company, “ensures compatibility and system stability”.
