P4 Chipset w/533MHz FSB

[jc14all]

Silicon Integrated Systems (SiS) debuts new P4 chipset (SiS648) and graphic chip series 'Xabre'(SiS330) at CeBIT (<i>March 15 2002</i>) <A HREF="http://www.digitimes.com/NewsShow/Article.asp?datePublish=2002/03/15&pages=10&seq=71" target="_new">(see article)</A>

"Paired with the SiS963 south bridge chip, the new chipset provides a high-performance P4-platform solution. Based on DDR400 architecture, the SiS648 is able to support Intel’s next-generation P4 processor with a FSB (front-side bus) speed of 533MHz."

"SiS also unveiled its new SiS330 graphics chip, announcing that it will launch four chips for the product line – the SiS328, SiS332, SiS334 and SiS336 – in the second quarter, targeting different market segments. The SiS330 series supports the AGP 8x and DirectX 8 interfaces, with the highest clock speed of the line able to reach 300MHz."

That simply sucks. DDR400 on a QDR533 processor will have the same problem at DDR333 has with the QDR400 bus already-the ememory bus operating at less bandwidth than the front side bus. If it allows you to use DDR400 with a QDR400 Northwood, it will at least solve problems for current P4's running DDR, but DDR533 will be needed for the newer Northwood "B" processors to insure full performance.

What's the frequency, Kenneth?

You just may get your wish for DDR533 by <A HREF="http://www.extremetech.com/article/0,3396,apn=3&s=1005&a=23473&app=1&ap=6,00.asp" target="_new">summer 2002</A> if the JEDEC flicks the green light to GO!

<b>DDR Moves Forward</b>

"One interesting issue that cropped up during the session on future memory technology support is DDR333. VIA is pushing DDR333 strongly, with the advent of the KT333 chipset. However, DDR333 isn't even finalized as a JEDEC spec yet, which means that DDR333 memory modules may not all be created equal. However, a standard is anticipated to arrive by summer."

Nice to know! But what I would REALLY want to do is run the Northwood "A" at 533 with DDR533 Cas2 SDRAM.

What's the frequency, Kenneth?
