Resumen del manual
Hardware and software designed to be used with any given Altered Assembly (AA) and BIOS revision level must assume that all errata documented for that AA and BIOS revision level are present on all desktop boards. Specification Clarifications describe a specification in greater detail or further highlight a specification’s impact to a complex design situation. These clarifications will be incorporated in the next release of the specifications. Documentation Changes include typos, errors, or omissions from the current published specifications. These changes will be incorporated in the next release of the specifications. General Information Basic Desktop Board D945GSEJT Identification Information AA Revision BIOS Revision Notes E57850-300 JT94510H.86A.0025 1,2,3 E57850-402 JT94510H.86A.0025 1,2,3 E57850-403 JT94510H.86A.0025 1,2,3 E57850-404 JT94510H.86A.0025 1,2,3 E57850-405 JT94510H.86A.0025 1,2,3 E57851-300 JT94510H.86A.0025 1,2,3 E57851-402 JT94510H.86A.0025 1,2,3 E57851-404 JT94510H.86A.0025 1,2,3 E57851-405 JT94510H.86A.0025 1,2,3 Notes: 1. The AA number is found on a small label on the component side of the board. 2. The N270 Processor used on this AA revision consists of the following component: Device Stepping S-Spec Numbers N270 C0 SLB73 3. The 945GSE Chipset Kit used on this AA revision consists of two components as follows: Device Stepping S-Spec Numbers 82945GSE A3 SLB2R 82801GBM B0 SL8YB Intel Desktop Board D945GSEJT Specification Update Summary of Changes Summary of Changes ® Desktop Board D945GSEJT. Intel intends to fix some of the errata in a future revision of the desktop board, and to account for the other outstanding issues through documentation or specification changes as noted. The following notations are used in the table: Doc: Document change or update that will be implemented. Plan Fix: This erratum may be fixed in a future revision of the desktop board, driver, or BIOS. Fixed: This erratum has been previously fixed. No Fix: There are no plans to fix this erratum. Shaded: This erratum is either new or modified from the previous version of the document. No. Plans Documentation Changes 1 Doc Update to the Integrator’s Note in Section 1.3 of the Technical Product Specification 2 Doc Update to the system power consumption information in Section 2.7 of the Technical Product Specification 3 Doc Update to Table 15 in Section 2.2.2.1 of the Intel Desktop Board D945GSEJT Technical Product Specification 4 Doc Note added to Table 2 Components Shown in Figure 1. No. Plans Errata There are no characterized erratum for this product Specification Changes The Specification Changes listed in this section apply to the Intel® Desktop Board D945GSEJT Technical Product Specification (Order Number E62862). 1. Correction to the Intergrator’s Note regarding power supply usage. 1.3 Processor The board is designed to support a single-core Intel Atom processor N270 soldered down. .. NOTE The board is designed to be passively cooled in a properly ventilated chassis. Chassis venting locations are recommended above the processor heatsink area for maximum heat dissipation effectiveness. Intel Desktop Board D945GSEJT Specification Update .... The board may be powered by using an external 12 VDC or internal 12 VDC power supply using a 2 x 2 pin connector. Use of an external 12 VDC power supply is preferred. 2. Update to the system power consumption information in Section 2.7 of the Technical Product Specification. 2.7 Power Consumption Power measurements were performed to determine bare minimum and likely maximum power requirements from the board, as well as attached devices, in order to facilitate power supply rating estimates for specific system configurations. System Power Consumption: Total Current Draw at 12V PSU Total Power Consumption Minimum Load 1.02 A 12.28 W Maximum Load 4.62A 55.44W Subsystem Power Consumption: Subsystem Current Draw at 12VPSU Subsystem Power Consumption 2GB SO-DIMM 0.17A 2.04W 3.5in SATA HDD 0.525A 6.24W 2.5in PATA HDD 0.3A 3.6W 4965AGN 802.11a/b/g/n 0.15A 1.8W Z-U130 USB flash drive 0.31A 3.72W SATA DVD-R/W 0.29A 3.48W Reserved header 0.925A 11.1W PCI riser card w/PCI cards 0.19A 2.28W Non-kbd/mouse USB ports 0.72A 8.64W Therefore, motherboard power consumption is as follows: • Board power at minimum load (system power at minimum load minus power from SO-DIMM): 12.28W - 2.04W = 10.24W • Board power at maximum load (system power at maximum load minus power from all subsystems in table above): 55.44W - 42.9W = 12.54W Intel Desktop Board D945GSEJT Specification Update 3. Update to Table 15 in Section 2.2.2.1 of the Intel Desktop Board D945GSEJT Technical Product Specification to address 3-pin fan header pinout inconsistencies. Table 1.
