ACorp 4D845A Socket 478 Motherboard

ACorp 4D845A Socket 478 Motherboard - PCSTATS
Abstract: The 4D845A mother board we're looking at today should appeal to thrifty buyers as ACorp produce relatively inexpensive motherboards for the value market.

Overclocking and Benchmarks

We were able to push overclock our Pentium 4 2 GHz (Williamette) to 2.2 GHz which equals a FSB of 110 MHz. That's quite a feat considering that other boards we've tested with this CPU on could only handle around 2.17 GHz. The other motherboards we used were pretty good ones at that.... from the MSI 845 Ultra to the Shuttle AV45GTR for example.

BAPCO Sysmark 2001 Source:MadOnion / BAPco

SYSmark2001 uses real world applications concurrently as an accurate way to test the system by following patterns that reflect the way real users work. SYSmark2001's workloads accurately represent today's updated business usage model. The benchmark runs at a realistic execution speed, with think times between application interactions, in order to emulate a desktop user's interaction with the operating system and applications.

Higher numbers denote better performance.

BapCo SysMark 2001 Benchmark Results
ACorp 4D845A Sysmarks Ranking
1. Internet Content Creation - 100 MHz 208
2 Internet Content Creation - 110 MHz 228
1 Office Productivity - 100 MHz 131
2. Office Productivity - 110 MHz 164

The ACorp does very well with the Bapco benchmarks. It's performance is on par with other i845D based motherboards, which is good to see coming from a value market solution.

Overclocking a little boosts performance as you might expect with the Internet content creation results increasing about 10% and the office productivity results going up an astonishing 20%!

Winstone 2001 Source: Zdnet

Content Creation Winstone 2001 keeps multiple applications open at once and switches among those applications. Content Creation Winstone 2001's activities focus on what we call "hot spots," periods of activity that make your PC really work--the times where you're likely to see an hourglass or a progress bar.

Business Winstone is a system-level, application-based benchmark that measures a PC's overall performance when running today's Windows-based 32-bit applications on Windows 98 ME, Windows NT 4.0 (SP6 or later), Windows 2000, Windows Me, or Windows XP which runs real applications through a series of scripted activities and uses the time a PC takes to complete those activities to produce its performance scores.

ACorp 4D845A Scores Ranking

Content Creation - 100 MHz

1a. Content Creation - 110 MHz 65.7
2. Business Winstone - 100 MHz 42.9
2a. Business Winstone - 110 MHz 45

The 4D845A does as well as other P4 DDR boards here. Unfortunately when dealing with office based applications the computer would be user limited.

Winbench 99 V1.2 Source: e-Testinglabs.com

WinBench 99 is a subsystem-level benchmark that measures the performance of a PC's graphics, disk, and video subsystems in a Windows environment. WinBench 99's tests can run on Windows 95, Windows 98, Windows NT, Windows 2000, and Windows Me systems.

WinBench 99 v1.2 Benchmark Results
ACorp 4D845A Score Ranking
1. Business Disk - 100 MHz 6240
1a. Business Disk - 110 MHz 5900
2. High-End Disk - 100 MHz 17900
2a. High-End Disk - 110 MHz 16400
3. Business Graphics - 100 MHz 566
3a. Business Graphics - 110 MHz 619
4. High-End Graphics - 100 MHz 897
4a. High-End Graphics - 110 MHz 1000

Hmm... The problem we had with low Winbench 99 disk scores also happens here with the ACorp 4D845A. It's rather odd since the 801 ICH2 has been around for a while and it is proven.

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance.

ACorp 4D845A Score

Multimedia Benchmark

1. Integer SSE - 100 MHz 7841 it/s
1a. Integer SSE - 110 MHz 8643 it/s
2. Floating-Point SSE - 100 MHz 9558 it/s
2a. Floating-Point SSE - 110 MHz 10540 it/s

CPU Benchmark

3. Dhrystone ALU - 100 MHz 3894 MIPS
3a. Dhrystone ALU - 110 MHz 4024 MIPs
4. Whetstone FPU - 100 MHz 1032 FPU/2442 MFLOPS
4a. Whetstone FPU - 110 MHz 1138 FPU/2660 MFLOPS

Memory Benchmark

5. Integer ALU - 100 MHz 2048 MB/s
5a. Integer ALU - 110 MHz 2259 MB/s
6. Float FPU - 100 MHz 2043 MB/s
6a. Float FPU - 110 MHz 2250 MB/s

The 4D845A coupled with our test P4 2 GHz has numbers that are almost identical to the reference CPU's Sandra compares against. The memory scores are lower then RDRAM, however, but they're pretty good for DDR.
