Alderwood chipset will support DDR2-667 memory04.06.2019
Just yesterday, we learned that the ECC memory support for DDR-II type chipset Alderwood (i925X) will not appear until July of this year, and in general the memory controller is not without some technical problems. Earlier, we received information that the chipset will be the pioneer of the conquest of 1066 MHz bus, although the exact timing for this event is not called.
Today, VR-Zone website reveals another secret opportunity Alderwood chipset. As reported by Taiwanese manufacturers, the chipset can support DDR2-667 memory in dual-channel configuration. Note that these characteristics have already met us in describing the properties of ATI RS400 chipsets, ULi M1685 and SiS 656. Consequently, the Intel is also aware of the need for a speedy transition to DDR 2-667, but plans to provide such a possibility this year only owners of expensive i925X platform type. DDR2-667 support in the "ordinary" chipsets will appear only in 2005, after the exit Lakeport.
It is no secret that AMD is also particularly applies to memory type DDR 2-667. The architecture AMD64 given frequency will offset high delay inevitably inherent memory type DDR-II. Mass availability of DDR2-667 memory should occur in the second quarter of 2005, and during this period, AMD plans to introduce DDR-II support for built-in memory controllers Athlon 64 processors.
In fact, the situation is different for Intel is not as significant as it might seem. From the viewpoint of synchronism with 1066 MHz memory bus useful DDR2-533, but the memory is able to block the lag DDR2-667 DDR-II from DDR-I. It is assumed that on the basis of DDR2-667 system will outperform a system based on DDR 400 about 5 %.
Some details about the other i925X chipset characteristics also emerge in the description of our colleagues. Firstly, the PAT mode Alderwood chipset will not have a special name, it seems to be an integral part of the chipset. Advantage over Grantsdale will be 3-5 %, and mentioned some another "short path" to the memory controller.
Secondly, some restrictions overclocking possibilities will exist at the chipset level. For example, when attempting to increase the frequency of the system bus by more than 12 % clock generator will be transferred to the nominal frequency. In fact, rumors about Intel plans to introduce a similar runaway protection existed for a long time, but to the practical implementation of the case has not yet been reached on the chipset level. Perhaps, the Intel will use this technology to manufacture their own motherboards, and third-party manufacturers will be able to bypass this protection without too much effort.
In the end, it would be a shame to buy a motherboard for $ 200-250 and lose acceleration capabilities :(. We hope that there will ultimately win the overclocker community and sympathetic to him motherboard manufacturers.
