Single bit error checking and correction within an 8-bit byte allows for single bit errors to be both detected and corrected when they occur. ECC Memory What it DoesĮrror Checking and Correction (ECC) memory is mostly considered essential in enterprise environments these days. AMD has much broader ECC support at the CPU level, but many AMD motherboards do not support ECC memory features so it is not universal. Intel Xeons, for example, support ECC memory, while even the new Core i7’s do not. In fact, unless one is running an Intel or AMD CPU that can support ECC memory unbuffered ECC DRAM is the only choice for most users. Today, the vast majority of memory used by desktops, notebooks, and mobile devices is unbuffered non-ECC (Error Checking and Correction) DRAM.
