Test Setup
| Performance Test Configuration | |
| Processor(s): | Intel 560 (3.6GHz) Socket 775 AMD 3500+ (2.2GHz, 90nm) AMD FX55 (2.6GHz) Socket 939 |
| RAM: | 2 x 512MB OCZ PC3200 Platinum Rev.2 (Samsung 2-2-2-5) 2 x 512MB Crucial/Micron DDR2 533 |
| Hard Drive(s): | Maxtor MaXLine III 250GB (16MB Cache) Seagate 120GB 7200RPM SATA (8Mb buffer) |
| Video AGP & IDE Chipset Drivers: | VIA Hyperion 455vp1 Intel Chipset Driver 6.0.0.1014 Intel Application Accelerator 4.0.0.6211 NVIDIA nForce version 4.24 |
| Video Card(s): | ATI X800 XT PCIe nVidia GeForce 6800 Ultra PCIe |
| Video Drivers: | AMD Catalyst 5.1 nVidia 71.40 Graphics Drivers |
| Operating System(s): | Windows XP Professional SP1 |
| Power Supply: | OCZ Power Stream 520W |
| Motherboards: | VIA PT894 Reference Board Asus P5GD2 Premium (915P) DFI LANParty UT 915P-T12 (915P) ECS PF4 915P Extreme (915P) Epox 5epa+ (915P) Intel 925XCV (Intel 925X) Socket 775 Gigabyte K8NXP-9 (nForce4) Socket 939 nVidia nForce4 Reference Board Socket 939 |
915/925X memory tests with boards using DDR2 (Asus, ECS, Intel 925x) used either Crucial PC2-4300U or Micron PC2-4300U memory modules. These are basically the same memory. The DFI boards, which runs either DDR2 or DDR, was benchmarked with DDR2. DDR2 was run at 3-3-3-10 timings at default voltage, which are faster timings than the SPD 4-4-4-12.
915 boards that use DDR (Epox), the VIA PT894, and AMD Athlon 64 boards were tested with OCZ PC3200 Platinum Rev.2, which is based on Samsung TCCD memory chips, at 2-2-2-5 memory timings at JEDEC standard 2.6V.
The ATI X800 XT PCIe was used for all 915 and Athlon 64 benchmarking, unless noted otherwise. Previous benchmarks of the 925X had been run with the nVidia 6800 Ultra PCIe and are included for comparison. Resolution in all benchmarks is 1024x768x32 unless noted otherwise.

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.
