Motherboard Review - ABIT IT5H
Performance
ctcm Benchmark results
The bus speeds 50, 55 and 60 MHz would all run at the fastest timing settings. Higher bus speeds, however, required the tuning of the BIOS timing settings. I've hence been distinguishing between the fastest settings, which ctcm would run at and the settings, which Windows 95 would run Winstone 96 flawlessly at. For everybody, who is using Windows 95 or who wants to be safe, the 'Windows 95 setting' results are the only ones that are realistical and really interesting, because they are the ones to certainly be free from crashes due to memory timing problems at these high bus speeds.
| Bus Speed [MHz] | Main Memory Speed [MB/s] |
|---|---|
| 50 | 34.5 |
| 55 | 39.1 |
| 60 | 42.5 |
| 66(max timing) | 47.3 |
| 66(Windows 95 setting) | 46.2 |
| 68(turbo frequency)(max timing) | 48.5 |
| 68(turbo frequency)(Windows 95 setting) | 47.3 |
| 75(max. timing) | 54.3 |
| 75(Windows 95 setting) | 52.1 |
Other Benchmark Results
| CPU Speed [MHz] | Winstone 97 | Quake Timedemoboth RAM types give the same frame rate |
|---|---|---|
| 166/66 | 37.8 | 14.7 |
| 171/68 (turbo) | 38.2 | 15.1 |
| 187.5/75 | 40.3 | 16.6 |
| 200/66 | 39.6 | 15.7 |
| 205/68 (turbo) | 40.8 | 16.1 |
Winstone 96 ran at the following configuration: Windows 95, built 950, Resolution 1024x768x256x60, Bus Master DMA drivers, Diamond Stealth 64 Video VRAM 2 MB, Quantum Fireball 1280A
The Winstone 97 results are slightly higher than the results of the IT5V with SDRAM. The Quake results are the exact same as with the IT5V.
