Chapter 1 1
Overview
All the new Socket-T motherboards come with a socket protector that has to be removed before you
fit the CPU. This is to prevent damage to the pins inside the CPU socket before the chip is inserted.
The new CPU socket is known as Socket-T and the new processors will be of LGA775 type. LGA stands
for Land Grid Array and means that there are no pins on the bottom of the CPU, although there are still contact
surfaces - no less 775 of them. The CPU interface has been moved to the mainboard socket and this is a
way for Intel to get fewer returns in terms of damaged CPUs due to bent or broken pins.
These two models (Aspire T670 & AcerPower FE) choose Intel Pentium 4 LGA 775 (socket _T) processor.
Intel 915GL+ ICH6 (Prescott) chipset architecture. This combination can run at 800MHz Front Side Bus and
provides On-Board VGA and discrete VGA support, which provides better performance than other
processors. This model with one PCI-Express x16 slot, three PCI slots (support PCI 2.2 spec.), 2 Dual
Channel DDR 1 memory slots (support up to 2GB), one P-ATA devices (HDD/ODD), two S-ATA devices
(HDDs), on board 10/100 LAN, and on board audio function.
Aspire T670 will be the product name for consumer market. AcerPower FE will be the product name for
commercial market. Please refer below table for more details address toward each chipset that be used in this
project : (It’s only for reference as guideline)
