Well, SiS Company seems to be really carried away by the idea of providing more Pentium 4 solutions: the new chipsets supporting these CPUs turn up in SiS’ plans at the speed of light. We have already told you about SiS646, SiS651, SiS655 and SiS660 chipsets (see this news story), and now we are ready to tell you a bit more about one more solutions from SiS, with the help of Digitimes.

This chipset seems to be some kind of transitional model between SiS646 and SiS655. Its specifications include the support of 533MHz Quad Pumped bus, AGP 8x, new SiS962 South Bridge (USB 2.0, ATA/133, IEEE 1394a) and (attention!) DDR400! What a surprise! Once again SiS tried to run ahead of time. The matter is that PC3200 standard (modules made of DDR400 chips) hasn’t been yet approved by JEDEC committee, and its support is already implemented. If this info gets confirmed, then all the upcoming SiS’ chipsets for Pentium 4 processors (SiS655, SiS660) also have to inherit PC3200 DDR SDRAM support.

The engineering samples of the chipset we have just told you about are planned for March. The mass shipments schedule is still unknown, however, we dare suppose that they will take place in Q3 at the latest (at the same time we should also see dual-channel SiS655 solution).

Now let’s wait for SiS647 and SiS649 :)
