Gaming Benchmarks and Conclusions

3DMark2001 SE Source: MadOnion

3DMark2001 SE is the latest installment in the 3DMark series by MadOnion. By combining DirectX8 support with completely new graphics, it continues to provide good overall system benchmarks. 3DMark2001 SE has been created in cooperation with the major 3D accelerator and processor manufacturers to provide a reliable set of diagnostic tools. The suite demonstrates 3D gaming performance by using real-world gaming technology to test a system's true performance abilities. Tests include: DirectX8 Vertex Shaders, Pixel Shaders and Point Sprites, DOT3 and Environment Mapped Bump Mapping, support for Full Scene Anti-aliasing and Texture Compression and two game tests using Ipion real-time physics. Higher 3DMark scores denote better performance.

3DMark 2001 SE Benchmark Results
ACorp 4D845A 3DMarks Ranking
1. 100 MHz FSB 7723
2. 110 MHz FSB 8265

While nothing outstanding, these numbers are quite respectable and what you might expect to see with the processor and video card we used to test the 4D845A. If we used a SDRAM based board, our scores would be about 1000 points lower.

Quake III Arena

Source: ID Software

Quake III Arena is a First Person Shooter (FPS) that revolutionized gaming as we know it. Using multiple light sources and having graphics textures that can fill videocards, even after 3 years it's still able to bring a cutting edge system to its knees.

2. 110 MHz 291.4

2. 110 MHz 79.8

Initial results are encouraging in these two QIII Arena Benchmarks.

1. 100 MHz 186.3
2. 110 MHz 193.9

Quake III Arena MAX 1024x768 nv15demo
FSB FPS Ranking
1. 100 MHz 49.6
2. 110 MHz 54.9

As the screen resolution is raised, our GeForce3 Ti500 starts becoming a bottleneck for the system. Still, those are some respectable numbers.

With this configuration, 1600x1200-32bit shouldn't be a problem for almost any game.


This particular 4D845A has proven itself to rank with some of the best P4 DDR motherboards we've tested which was a bit unexpected. Even though Acorp mainly target the value markets with their mainboards, the 4D845A we tested, was able to compete on a level that seemed to place it with higher-end solutions. Thanks to the stability of the Intel i845D chipset , we didn't experience any problems during testing. The board didn't BSOD or crash once unless it was due to user error.

With an 4X AGP slot and six PCI slots there is a lot of room for expansion should you require it, and it was nice for Acorp at least group the power connectors in one spot rather then all over the PCB like some other manufacturers do.

While there are only two DIMM slots for DDRAM that is the standard Intel spits out for mainboard manufacturers to follow. The C-Media 8738 chipset would have offered users a better acoustic solution, but VIA's AC'97 codec should be good enough for most users who aren't blessed with more than $20 computer speakers. I guess you can't win them all though.

Unfortunately I wasn't able to find the Acorp 4D845A on price watch so I'm not sure how much this board will retail for, however if it's like other Acorp boards, it will probably be inexpensive. With the 4D845A's excellent performance and slew of tweaking and overclocking options, this board would be good for anyone to consider who is in the market for a basic Pentium 4 motherboard!
