Embodiment Construction

[0014] DDR2 has 240 pins and uses a power supply of about 1.8V (volts); while DDR1 has 184 pins and uses a power supply of about 2.5V. DDR2 and DDR1 have different pin numbers and used voltages, so DDR1 cannot share the DDR2 connector. Instead, there must be a riser card that can be connected to the DDR2 connector. The riser card has a grounding terminal and makes the riser card DDR1 connector can be connected; and there must be a voltage adapter, whether the input terminal of the voltage adapter is connected to the ground terminal of the adapter card, respectively provide the voltage used by DDR1 or DDR2.

[0015] The present invention makes DDR2 or DDR1 share the method for a motherboard, is to make motherboard combine a voltage converter and a DDR2 connector; voltage to the DDR2 connector; when connecting the motherboard with a DDR1 connector, connect the DDR2 connector to one end of an adapter card, connect the other end of the adapter card to the DDR1 connector, and conne...

Abstract

The method and structure of making DDR2 or DDR1 share one main board has the main board combined with one voltage converter and one DDR2 connector. When the main board is to be connected to DDR2, the voltage converter outputs one proper voltage to the DDR2 connector; and when the main board is to be connected to DDR1, the DDR2 connector is connected to the DDR1 connector via one converting card and the input of the voltage converter is connected to ground end of the converting card, so that the voltage converter output one other proper voltage to the DDR1 connector. The main board can be combined with DDR2 or DDR1 optionally and this provides improved performance.

Description

【Technical field】 [0001] The present invention relates to a method and a device for respectively combining different memories with a computer motherboard, especially a method and a device for respectively combining DDR1 and DDR2 with the same motherboard. 【Background technique】 [0002] With the ever-changing changes in computers, the memory has changed from the past EDO memory, SIMM memory, etc. to the higher-speed Rambus memory, DDR1 (DOUBLE DATA RAM I memory) and the upcoming DDR2. With the rapid development of memory manufacturing technology, whoever can grasp the changes in a timely manner can win in the fiercely changing market. [0003] DDR2 will be launched soon, and it is foreseeable that motherboards that cooperate with DDR2 will gradually become the mainstream in the market. However, since the price of DDR1 is bound to be cheaper than DDR2, there will still be a market demand for DDR1 motherboards. At present, in the design of motherboards, there is still no pla...
