Notes
It's becoming a common and satisfying theme that there was nothing untoward to report during installation and testing. ABIT's VIA K8T890-powered motherboard was tested against an ASUS nForce4 SLI (with single ATI RADEON X850 XT PE PCI-E card), and an Intel Pentium 4 660 and i925XE motherboard combination.
Clock speeds were as follows:
3630.8MHz - EPoX 5LWA+ (i925XE) - Intel Pentium 4 660
2405.4MHz -ABIT AX8 (VIA K8T890) - AMD Athlon 64 FX-53
2404.7MHz -ASUS A8N-SLI Deluxe (nForce4 SLI) - AMD Athlon 64 FX-53
Note that if default settings are chosen from the BIOS, the AX8 boots up at an inflated 204.3MHz FSB. It's effectively performance for free, but the FSB was manually adjusted to 200MHz when testing.
Overclocking
Front-side bus overclocking tests were undertaken by dropping the FX-53's multiplier to 8x, reducing the HyperTransport link to 3x, locking both PCI and PCI-Express buses to their respective default levels, reducing the RAM setting to DDR266, and, finally, increasing northbridge voltage to the maximum permissible limit of 1.65v. It was disappointing to note that the maximum stable FSB speed was a mere 232MHz, or 32MHz above stock. Any higher and a couple of problems were immediately appparent; Windows XP failed to load correctly at all times and sporadic PC freezing and rebooting occured.
Of course, one sample's poor FSB ceiling doesn't automatically infer that all retail models will have the same fate. If web reports are anything to go by, 250MHz+ FSB is attainable for most. Alas, here, it wasn't.
