FSB Overclocking Results
For FSB overclocking, the following setup was used on the 8S655FX Ultra:| Front Side Bus Overclocking Testbed | |
| Processor: | 2.4C Pentium 4 (800MHz FSB) |
| CPU Vcore: | 1.525V (default) |
| Cooling: | Thermalright SK-900U with 120mm Thermaltake Fan |
| Memory: | Two 256MB Corsair 3200LL at SPD |
| Power Supply: | Enermax 350W |
Using the above overclocking setup, 239MHz FSB was the highest reliable overclock that we were able to sustain with the 8S655FX Ultra. Unfortunately, this is ridiculously low compared to 865PE and 875P motherboards that have been available on the market for many months, and not even better than single channel DDR 848P motherboards, such as the ASUS P4P800S-E that just arrived on the market.
There’s not much more we can comment on in terms of FSB overclocking, except to say that Gigabyte has assured us that they are working away on a BIOS that should not only improve performance, but overclocking ability. There is some light down the end of the tunnel, but we’re betting on a newer spin of the SiS 655FX (SiS 658?) to turn things around.

Error on page 7 (too high FSB speeds):In addition, we ran several other tasks: data compression, various DX8 and DX9 games, and apps, like Word and Excel. Moreover, Prime95 was running in the background. Finally, we ran our benchmark suite, which includes ZD Winstone suite, Unreal Tournament 2003, SPECViewperf 7.0, and Gun Metal Benchmark 2. While we were able to boot and run some tests at speeds as high as 287MHz FSB and at default voltage on the Gigabyte 8S655FX Ultra, 262MHz was the highest achievable overclock attainable without encountering any reliability issues.
