large enough to ensure that processors will not crack. LGA 775 compatibility Compatibility is quite variable, as earlier chipsets (Intel 915 and below) tend to support only single core NetBurst Pentium 4 and Celeron CPUs at an FSB of 533/800 MT/s. Intermediate chipsets (e.g. Intel 945) commonly support both single core Pentium 4-based CPUs as well as dual core Pentium D processors. Some motherboards using the 945 chipset could be given a BIOS upgrade to support 65nm Core-based processors. Other chipsets have varying levels of CPU support, generally following the release of contemporary CPUs, as LGA 775 CPU support is a complicated mixture of chipset capability, voltage regulator limitations and BIOS support. For example, the newer Q45 chipset does not support NetBurst-based CPUs such as the Pentium 4, Pentium D, Pentium Extreme Edition, and Celeron D. Virtualization capabilities Some Core 2 and other Socket 775 processors are capable of hardware-accelerated virtualization. However, more recent hypervisors might not be compatible with these CPUs because they lack support for Extended Page Tables.
