FIC PA-2013 2MB Cache Versionby Anand Lal Shimpi on December 16, 1998 1:10 PM EST

In 1998 however, things changed incredibly, the Super7 market proved to be a profitable one, and manufacturers either kicked themselves for not jumping on the bandwagon at the start (cough-ABIT-cough) or smiled knowingly as their Super7 products took off in sales.
As with the release of BX motherboards, Super7 motherboards came in generation waves, with each following generation bringing a new feature or two to the table, and in the tradition of evolution, FIC brought their next generation Super7 motherboard to the eyes of the eagerly awaiting market, it's about time that you all met the Super7 with K6-3 written all over it. What does that mean? Well, the K6-3 will come with its own integrated 256KB of L2 cache, and will cause the motherboard's on-board cache to be bumped down to a Level 3 cache...so picture this for a moment: a K6-3 running at 450MHz, 64KB of L1 cache, 256KB of L2 cache, and 2MB of L3 cache courtesy of the new FIC PA-2013. Not a bad dream, but how much of a performance increase will that 2MB L3 cache provide you with, and what happens between the time between now and when the K6-3 is released? Will you enjoy the board or will it be a pain to deal with? Let's find out as AnandTech gives you an exclusive look at the new FIC PA-2013 VIA MVP3 Super7 motherboard with 2MB of cache. It's finally here...

Do not compare newer ratings to older ones, the newer ratings are much more aggressive

|Like the 512KB/1MB versions of the PA-2013, the 2MB board comes outfitted with a 4/2/1 expansion slot configuration (PCI/ISA/AGP) and 3 DIMM slots. The peripheral and memory expansion slots are laid out on an ATX PCB (Printed Circuit Board) approximately the size of most Pentium II BX boards like the ASUS P2B and the Epox P2-112A. The 4 - 512KB L2 cache chips take the place of the four chips present on the 1MB board and run adjacent to the Socket-7 IC in the form of an L-shape. The 2MB of L2 cache starts off by enabling the VIA MVP3 chipset's 508MB cacheable memory area, up from the 254MB of the 1MB version and the 127MB of the 512KB version.
The layout of the board hasn't changed at all since the original introduction, the ATX power connector is found at the top of the board placed almost flush against the first DIMM slot, and wedged next to the I/O ports. Surrounding the Socket-7 IC and around the memory slots are a few small to mid-sized capacitors, with a great number of them populating the area around the switching voltage regulators.
|Like all newer MVP3 based motherboards, the PA-2013 ships from the factory with revision 'CE' of the chipset which eliminates the problems the chipset had with i740 based graphics accelerators. The CE North Bridge is what drives the AGP 2X compliant port which is located just left of the chip itself. A little peek into the future is possible with the PA-2013, looking to the area just below and to the left of the AGP slot AnandTech noticed a little label for a Front-USB port 'F-USB' with a connector next to the text, unfortunately the connector was hammered in, but it does look like we can expect to see some Front USB ports on more motherboards in the future. Wonder how long it would take to get those USB ports off of the ATX Back Panel and create a new opening on the front of most cases...
FIC is up to their usual standards with the motherboard manual bundled with the PA-2013. The written documentation includes the settings for all officially supported bus speeds as well as the overclocked 75/83/112/124MHz settings for pushing your luck. Clock multipliers ranging from 1.5x to 5.5x are also documented, not to mention the excellent support for core voltage settings ranging from 1.8v to 3.5v in 0.1v increments. FIC also includes a fairly complete table of CPU settings for the most popular chips in the manual which is a handy tool for first time builders, or even those who are just looking to get a kick out of reading up on older CPU settings ;)
The PA-2013's stability was not sacrificed under normal operation as a result of the 2MB of L2 cache, as the AnandTech tests proved, the system crashed a total of 4 times over a 24 hour testing period while running a variety of business and 3D gaming applications. Like the original PA-2013, the 2MB version does come with Trend's ChipAway BIOS Virus Protection program that prevents boot sector viruses from loading even before your system starts up your operating system, just an added safety feature which may come in handy in this download-driven Internet world.
|The PA-2013's performance rose an average of 3% in business applications, with performance increases peaking at the 5 - 7% level, placing it at the top of the Super7 motherboard performance charts. As you might be able to guess, the improvements in 3D games is virtually un-noticeable, so if you have a PA-2013 or another Super7 board right now that you're happy with, there is no point to upgrading to this 2MB version simply because of the performance increases. Even L2 cache dependent games such as Unreal didn't receive any improvement in performance as a result of the larger cache, in this case, their performance was being limited by the actual speed of the cache, not the size.
As with the older PA-2013's, five PCI slots would've made this board the dream of many users, unfortunately, in order to conserve space, the PA-2013 was only outfitted with 4. The positioning of the Socket-7 CPU interface isn't ideal for cooling as the path of airflow from your ATX power supply will pass directly over your memory banks, leaving your CPU fan to take care of all of the cooling duties for your CPU. The positioning of the ATX power connector is also a bit of a pain to deal with, especially if you have all three SDRAM banks occupied.
Now here's the real problem with that 2MB L2 cache, the board wasn't reliable enough at any overclocked FSB speeds (112MHz or 124MHz) most likely as a result of the quality of the L2 cache chips. Where the older PA-2013's outfitted with 512KB or 1MB of L2 cache could perform quite reliably at 112MHz, the 2MB version AnandTech tested couldn't. In the future this problem may be addressed and corrected with higher quality L2 cache, however that won't come without an added cost to the end user, making overclocking on this board, other than with the 100MHz FSB, undesirable.
