Nvidia Corp., a leading designer of graphics processors and chipsets, recently admitted that its most-recent chipset for Intel Corp.’s microprocessors may cause data corruption in case processor bus and system memory are overclocked. Earlier customers blamed previous-generation Nvidia’s core-logic sets for data corruption under the same circumstances.

Apparently, when computer enthusiasts overclock processor system bus (PSB) and memory clock-speeds on systems that are based on Nvidia nForce 790i-series core-logic, they may experience data corruption on hard disk drives. Earlier end-users complained about the same issue on systems powered by previous-generations Nvidia nForce chipsets.

“Nvidia has received reports of data corruption when using certain high speed memory and overclocking the front side bus.  Our engineers are currently investigating this issue and as soon as we have more information, we will provide an update to this knowledge base article,” a statement by Nvidia in its technical support forums reads.

Even though this is not the first time when customers complain about data corruption, neither Nvidia nor any of the mainboard makers have disclosed the reasons of the problem.

Nvidia nForce 790i Ultra SLI core-logic supports Intel Core 2 processors with up to 1600MHz processor system bus and overclocking capability beyond that, dual-channel DDR3 memory with speeds over 2000MHz, three PCI Express 2.0 x16 slots for graphics cards, six Serial ATA-300 ports for hard disk drives and so on.

I do not think it\'s a serious problem.
Guarantee OC doesn\'t imply guarantee an OCed stable environment.

it depends on how the problem is triggered.
