The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2] Many or most Xeons subsequent to this support VT-d.
Intel provides support in the MRC for all fully validated memory configurations. For non-validated configurations, a system designer should work with their BIOS vendor to produce a working MRC solution ... The MRC in the system BIOS needs to know the specification of the attached system memory. Most of this info should be contained in the ...
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
Early registered RAM modules were physically incompatible with unregistered RAM modules, but the two variants of SDRAM R-DIMMs are mechanically interchangeable, and some motherboards may support both types. [8] Load Reduced DIMM (LR-DIMM or LRDIMM) modules are similar to R-DIMMs, but add a buffer to the data lines as well. In other words, LR ...
945PL - No support for 1066 MT/s bus, only supports 2 GB of memory. 945G (Lakeport-G) A version of the 945P that has a GMA 950 integrated, supports a 1066 MT/s bus. Sub-versions: 945GC - Same feature reductions as 945PL but with an integrated GMA 950. 945GZ - Same as 945GC but only supports DDR2 memory at 400/533 MT/s.
In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...
In the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the data transfer rate between the DRAM memory and the memory controller by adding more channels of communication between them. Theoretically, this multiplies the data rate by exactly the number of channels present.
Motherboards, chipsets and processors that support ECC may also be more expensive [vague]. ECC support varies among motherboard manufacturers, so ECC memory may simply not be recognized by an ECC-incompatible motherboard. Most [vague] [when?] motherboards and processors for less critical applications are not designed to support ECC. Some ECC ...
