Jetway includes all the settings that most overclockers are likely to use, with adequate frequencies and voltage ranges. We prefer actual voltage settings, rather than plus or minus values, however, and are especially annoyed when forced to calculate percentages to reach our voltage goals.
The HI04 Overclock menu is just over one page long, with settings for CPU multiplier, FSB clock, and key voltage levels.
A DRAM timings sub-menu contains the most frequently adjusted latencies.
Three BIOS configurations can be saved for later retrieval using the User OC Profile utility. These value remain stored even if BIOS is “Cleared”, allowing overclockers to get back to a workable setting after a failed boot attempt.
One other thing we noticed about Jetway BIOS is that its “Onboard Device Function” menu must be entered to enable “USB Storage Legacy Support”, which is disabled by default. We updated BIOS from a bootable USB flash drive after enabling this feature.
