The board has the usual complement of connectors and peripheral support. There are two PCI slots as well sharing space with the PCI Express slots. The extra slot can be used for other PCI Express adapters such as Adaptec's 4805SAS PCI Express RAID SAS controller (EiED Online> Building A SAS RAID File Server, ED Online ID 12386). There are three PCI Express slots spaced widely to handle a pair of AMD/ATI X1950XTX CrossFire video adapters. This will be significant as servers and power users migrate to virtual machine environments for flexibility and security. The 64-bit quad core processor supports Intel VT, its enhanced virtualization support. They share the cache and system bus interface. Like AMD, Intel uses a core multiplexing technique that employs two dual core dies on the same substrate. A new pre-fetch algorithm is supposed to improve L2 cache access. The superscalar architecture allows each core to execute four instructions per clock cycle. The shared L2 cache is dynamically allocated to each processor core. The quad core processor comes with 8 Mbytes of L2 cache. It employs all of Intel's latest technology including 64-bit support, enhance SpeedStep and the latest virtualization technology. The cores run at 2.66 GHz using a 1066-MHz system bus to deliver unrivaled performance, at least for this year. The ATX D975XBX2 motherboard is designed to accept the quad core, Core Duo 2 Extreme QX6700 processor with its 775-landing multichip package. That's Intel's D975XBX2 motherboard, Bad Axe 2, with the 975X Express chip set that supports AMD/ATI's multiboard CrossFire video adapters. The table below lists parts that passed testing conducted using the Intel® Self Test program for Intel® Desktop Board D975XBX2.It's got four processor cores, four SATA interfaces and four more SATA interfaces with its built-in RAID controller. These part numbers might not be readily available throughout the product life cycle. Memory listed completed testing by the memory vendor or by Intel using this test plan. Intel supplies the memory vendors that participate in this program with a common memory test plan to use as a basic checkout of the memory stability. Third-party tested memory occurs as requested by the memory vendors and is tested at an independent memory location that is not a part of Intel - Computer Memory Test Labs (CMTL). The table below lists the resulting working memory frequencies based on the combination of DIMMs and processors. For example, if DDR2 800 memory is used with a 533 MHz system Bus frequency processor, the memory works at 533 MHz. Regardless of the DIMM type used, the memory frequency is either equal to or less than the processor system Bus frequency. The following table lists the supported DIMM configurations. Performance and reliability can be impacted or the DIMMs might not function under the designated frequency. If non-SPD memory is installed, the BIOS tries to correctly configure the memory settings. This structure allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance.

To be fully compliant with applicable DDR SDRAM memory specifications, the board should have DIMMs supporting the Serial Presence Detect (SPD) data structure. Remove the Primary PCI Express* x16 (electrical x16 or x8) video card before installing or upgrading memory to avoid interference with the memory retention mechanism. DDR2 800, DDR2 667, and DDR2 533 MHz SDRAM DIMMs.Unbuffered, single-sided, or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.The board has four DIMM sockets and supports the following memory features:
