ICH9: Matrix, Turbo Memory

The side southbridge the ICH9 makes its aspect. Let us start with what these tiddlywinks bring obligatorily, namely the support of 4 ports S-ATA, the absence of any port P-ATA (additional controllers to consider for the mothers of manufacturers of council), and the management of the eSATA. It acts for the recall of this port located on the back dish of the council and to aim of mother replacing the USB and the cable of fire for the management of the external hard drives in particular. That controlled by the ICH 9R supports the multiplication of the port, which wants to indicate that it will be possible to be connected to 4 discs on this only left via a simple external case with the nappage specifying of this fact the ide.

The side of the optional functionalities, memory of Turbo fact its aspect on the councils of mother for the PC! One of its advantages sees the strongly reduced blow, since the fall of the consumption which it can occurs via less request of the hard drive becomes negligible on a scale of PC. Same manner, the PC generally presents memory more than read/write which the portables, which should reduce the interest of this flash of memory. Blow, instead of kits 512 put-band or 1 gigaoctet one passes to the choices with 1 gigaoctet or 4 gigaoctets. The interface is always the express train left X1 (250 Mb/s bidirectional) of NCV. This memory will be sold by Intel directly to the manufacturers (as for the portables), who authorizes the possibilities of levelling via the development of an optional module suggested by the manufacturer, who does not appear however very probable. On the one hand, some will propose councils of mother with this welded memory. The prices were not however indicated and will be with it only on June 4. While hoping that the stable and powerful drivers will be quickly available, under the penalty to see this technology trailing an bad image definitively.

The quiet system of technology makes its aspect. It deals with management the speed of the variation of the processor of ventilator according to the temperature, obviously with an aim of avoiding the traditional thermoregulation which has like disadvantage of accelerating the number of revolutions and thus the noise with the least request of the processor, which is unpleasant. It would thus exploit the margin available to the processor before reaching the limit needing a fall of its frequency and its tension in order to remain longer with a certain number of weak revolutions, although in the case of a constant use without interruption, this technology cannot obviously stop the speed of increase. A technology thus debatable in so far as it does not change anything with the need a quiet ventilator for those which are sensitive to the noise, with stronger reason in date of much of manufacturers of the councils of mother have identical technologies already.

3 versions different from the ICH9 are available. The ICH9DH that is reserved for the central media with the support of the Viiv (from where the presence of the storage of Matrix, which does not control the RAID but the AHCI, essential to the Viiv). Attention, it is also the first to integrate 6 ports S-ATA, the initial version integrating some always only 4.

To finish, the version R is like increasingly more complete, the only one to control the incursion of Matrix, the memory the Turbo one and the multiplication of the ports.
