its say's it will support 166mhz(333mhz) DDR-SDRAM for the P4. Wow SiS is on a fire lately.

Nice Intel and AMD users get a Cookie.... :smile: Yummy :smile:

Yup, heard about this lastweek. Cannot wait. I was gonna sell my PIII 1.0Ghz and get the Tualatin. Then I saw the price cuts for the P4 scheduled for the 26 and 28 of this month, with the new socket 478. But I already told someone to buy my PIII, so I got a 1.0Ghz AXIAR-Y T-Bird yesterday. Brookdale is only SDRAM, so I was going to get the VIA P4X266 chipset (but heard, VIA bad, naughty), so now this.

Damn, there are a lot of choices right now. What to do?

i845 will support DDR SDRAM probably next winter. By then everyone will probably have bought the SiS already.

Hopefully a revised i845 will support DDR 400 (200MHz, aka PC3200) as Intel originally planed for their DDR conversion.

unfortunately current i845 chipsets are supposed only to support PC1600 DDR so I gues we can rule out i845 as a high performance system - ever.

Considering how UNDER utilized DDR is in Athlon systems, we may be surprized, maybe PC1600 is all it will really need?

I won't say that is not possible, but if you install PC1600 over PC2100 you'd expect to see a system performance drop. I guess it may be theoretically possible that a P4 would seen no performance gain of PC1600 over PC2100, or 2400, but it is difficult to see how.

I read reviews on toms site saying the new chipset only supports PC1600 but that they run PC2100 just fine.
Maybe its through overclocking, but hey no one ever turned away free speed that I know of.

Yes, I remember that. Use PC2100 when overclocking your 2GHz Northwood to 2.66GHz.
