Testbed:

JMke's Test Setup
CPU	Intel P4 2.4 "C"
Mainboard	* Chaintech CT-9CJS * Asus P4C800
Cooling	Zalman CNPS7000-CU
Memory	2 * 256Mb PC3700 OCZ Rev.2
Video	nVidia Geforce 4 Ti4600

Performance:

We ran the benchmarks with 2 different settings, one time at default FSB speed of 200, the memory timings were set at CL2 2-3-5. Then we increased the FSB to 250 with memory timings at CL2.5 3-3-7. PAT was auto-enabled during all tests.

Interesting to note is that the Chaintech puts the FSB at 202.9 when running at default speeds.

Let’s start of with one of the most popular DirectX benchmarks:

The onboard sound has an impact on performance but no more/less than expected.

In the majority of tests we see the Chaintech I875 solution pull ahead of the Asus P4C800, solid performance at default speeds and even better when overclocked!
