PT880 PRO: The "Step-Up" Chipset
The PT880 PRO is the lowest cost of the new PCI Express chipsets. VIA believes that the PT880 PRO will appeal to many buyers, since it offers upgrade possibilities that just aren't available on other Socket 775 boards.
The most unique feature is the availability of a full AGP 8X slot on a PCI Express motherboard designed for Socket 775. There is also a PCI Express video slot, but VIA tells us that the PCIe slot will be limited to x4 operation. Based on the performance in our past reviews, an x4 PCIe should certainly be fast enough for any current PCIe video cards. Significantly, an AGP and PCIe can both run simultaneously to power up to 4 monitors in a multi-display configuration.

DDR dimm have 184 pin so:- Amd socket 939 = socket 754 + 184 pin = 938 pin
- Amd socket 754 - 184 = 570 pin (with out the on board memory controller)
Intel new P4 socket have 775, why?

while the above are correctI refer to the fsb 1066 is not working currently statment --- how can this be good for overclocking?
its probably not working because of the AGP/PCI lock -- im an owner of the kt800 chipset and while the lock does work as they claim -- it kills itself at around 270fsb

Wow, these VIA chipsets sure have the potential to give competition to Intel's and Nvidia's offerings. I hope they execute this one properly.2 - Yeah, there's a pretty good chance much of what we see with these chips will be brought to whatever VIA's working on for their upcoming chipsets for AMD's K8 processors

The fact that the PT880 supports both AGP and PCIe makes it very attractive. I wonder if VIA will implement the same with their AMD line...ChineseDemocracyGNR - Monday, January 31, 2005 - link
Wow, I'm impressed. I didn't expect the PT894 to keep up with the 915/925 chipsets, but it's actually faster in a number of benchmarks.The VT8251 is very impressive too, specially if they can get it out soon for K8T890 boards. That's the best southbridge in my opinion, compared to Intel's ICH6 family and nVidia's nForce4 Ultra.
