|Judging by the Motherboard Specifications alone, one would expect the AX59Pro to be a low-end BX motherboard, the only part preventing that from becoming reality is the strong presence of the VIA MVP3 chipset. Bordered on the South by an standard 512KB of Level 2 cache (1024KB optional, AnandTech tested a board equipped with 512KB) and closed off to the North by 3 DIMM and 2 SIMM slots, the MVP3 chipset is completely surrounded by the key components it provides power to. To the left of the VT82C598AT chip (Northbridge - the larger of two chips making up the MVP3 chipset) lies the AGP slot followed by 4 PCI slots and 2 ISA slots, all of which accept full length cards. While this may not seem like an important feature to look for, with quite a few Super7 (Socket-7 + AGP + 100MHz Front Side Bus support) motherboards designed in such a manner that one cannot even use a single Voodoo2 board due to the length of the card it is important that you look for a board that will allow you to use full length PCI cards if you plan on installing any.|
Courtesy of the MVP3 chipset, users have the option of taking advantage of the 2 SIMM slots on the AX59Pro by enabling a pseudo-synchronous memory bus operation mode which clocks the memory bus at the AGP clock (usually around 66MHz) with the CPU and L2 cache deriving their speed directly from the Front Side Bus (FSB). Of course, meeting the requirements for a true Super7 motherboard, the AX59Pro features both a 1/2 and 1/3 PCI clock divider to keep the PCI bus running as close to 33MHz as possible.
The layout of the AX59Pro is fairly spacious, while not as large as the Epox MVP3E-M it does pack a considerable punch. AOpen managed to outfit the AX59Pro with a highly configurable voltage list, ranging from core voltages of 1.30v to 3.5v with the steps between 1.30v and 2.05v made in 0.05v jumps and those made between 2.0v and 3.5v in 0.1v leaps. It is doubtful that you'll ever need to use the 1.30v setting, but it is nice to know that the AX59Pro offers you more than just the standard options when it comes to voltages, and in this case, also when it comes to Bus Frequencies. The AX59Pro goes above and beyond the 100MHz FSB setting by offering an overclocked 112MHz FSB speed for those daring enough to give it a try. In addition to 100/112MHz FSB frequencies, AOpen's MVP3 beauty features the usual set of 60/66/75/83MHz settings as well as the unique 90MHz setting. The clock multiplier and core voltage settings are controlled via a corner located Dip Switch on the board, with the FSB settings controlled by a jumper block beneath the first DIMM slot.
Standard with the AX59Pro is AOpen's first class User's Guide made entirely out of recycled paper. The information contained within the documentation thankfully doesn't reflect the recycled nature of the paper it was printed on as it isn't simply a "cut-and-paste" of generic manuals, rather an original collection of data/useful information that closely pertains to this specific product alone, a concept a surprising number of manufacturers have failed to grasp. As with most newer AOpen motherboards, the AX59Pro's attractive box also is home to the AOpen Bonus Pack CD-ROM which contains a current version of Symantec's Norton AntiVirusTM software. The CD also contains the standard set of drivers, Flash BIOS Utilities, Desktop Managers, and on-line documentation.
In the tests AnandTech conducted, the AP59Pro made it as high as 315MHz (90 x 3.5) reliably, with 100 x 3.0 being the fastest overall setting due to the performance boost courtesy of the 100MHz FSB speed. Stability at all overclocked speeds achieved reliably was not a factor at all, not to mention the board's rock solid performance at all standard speeds. The performance of the AX59Pro is currently closest to that of the Epox MVP3E-M which is available with a full megabyte of cache, a feature that not only increases in the cacheable memory limit of the motherboard to 256MB but offers a slight performance boost in some situations over boards equipped with only 512KB of cache. Even in spite of this, the 512KB AX59Pro (128MB Cacheable Memory Area) came quite close to the performance of the MVP3E-M, close enough to be considered virtually identical.
Where is the one PCI slot that we sacrificed a third ISA slot for? The AX59Pro would have probably taken the lead among its competitors had it featured a full 5/2/1 (PCI/ISA/AGP) expansion slot configuration instead of the incomplete 4/2/1 setup it boasts.
In spite of the excellent layout of the motherboard, the jumpers can still be a pain to configure, and the CPU Socket does not fall in the path of the ATX Power Supply, therefore posing some possible cooling issues when overclocking you system.
Another disappointment was the 112MHz FSB setting which wasn't stable enough to completely boot into Windows 95, a shame since running a K6-2 at 336MHz (112 x 3.0) would be a dream come true for quite a few soon-to-be K6-2 owners.
AOpen has the best ATX MVP3 motherboard AnandTech has looked at so far, although that may seem like much the only board it has to compete with is the Epox MVP3E-M which doesn't fall that far behind it in terms of overall value.
