j'ai envoyé un mail a EPOX pour cette histoire !!
voila la reponse :
EPoX is Commenting on technical issue:
Conflict between the CE6 capacitor on EP-8KHA/+ and VisionTek GF4 Ti4600 graphic card
Taipei/Taiwan; 06-MAR-2002 - EPoX Computer Co., Ltd., a leading developer and manufacturer of high end mainboard, storage and communication solutions is giving today an official press statement, regarding technical issues being discovered by users when using an EP-8KHA, EP-8KHA+ and a VisionTek GF4 Ti4600 graphic card.
Mr. Thomas Huang, VP of Research & Development Dept. of EPoX Computer said: "Regarding the high capacitor on EPoX motherboard EP-8KHA, EP-8KHA+, it was designed to optimize the stability of a DDR motherboard. While DDR solution was first introduced in the first quarter of 2001, according to the technical information the power consumption of the DDR memory will be much higher than SDRAM architecture. EPoX's technicians decided to use switch circuit design. And the output end came important. After evaluating all the graphic cards sold in the market and ensure there was no mechanism conflicts, to keep wider tolerance in memory voltage and current, the bigger capacitors (1500μf/6.3V, LSR capacitors) was complemented to reserve big space and optimize the voltage stability. Each EP-8KHA and EP-8KHA+ even equipped with 2 of them.
However according to the real experiences of using the selling DDR modules in the market, the power consumption is much lower than it was reported. In fact one 1500μf/6.3V, LSR capacitors is enough to handle it. In EPoX internal testing, the stability and overclockability is still very high without any influences."
By case users has difficulty in installing VisionTek GF4 Ti4600 graphic card on EPoX EP-8KHA+ and EP-8KHA, the first solution will be removing the CE6 capacitor. If users are not experienced in solder iron, they can use pliers to remove this component. If users are still confused with it or have any questions, they can contact any EPoX branch office in worldwide.
En gros ils ont mis ces condensateurs pour ameliorer la stabilité en croyant que la memoire DDR consommait beaucoup d'energie !!
Or ils ne servent a rien et pour ceux qui achete une Gef4 ils disent d'enlever un condensateur !!!
