The Soyo SY-6ICA Motherboard
Soyo's RAMBUS Driven i820 Offering

By, Dave "Davo" Altavilla - 5/17/00

Here we are again with yet another look at a motherboard from a top notch supplier based on Intel's controversial chipset, the i820.  Whether you are interested in SDRAM supported designs with Intel's infamous MTH (memory transfer hub) or a somewhat expensive RAMBUS implementation, there is  definitely no shortage of opinions to go around about this new chipset and the motherboards designed with it.   We tend to avoid the rumor mill and chatter surrounding the industry and the products it spawns but rather approach reviews of the products made available to us with an unadulterated "benefit of the doubt" approach.  Yes, RAMBUS is expensive now but as we have all heard, it is coming down in price quickly.  Intel has a vested interest here and you can bet they are doing their best to work out the issues.

As a result, in the following pages we will evaluate the Soyo SY-6ICA i820/RAMBUS Motherboard based on its own merits, design quality and performance.  We'll save you the chatter and hype about the chipset that it is built on and just give you the facts about how the board is built and performs.  Fair enough?  Good, let's move out.

Alright then, let's start with the basics.  Firstly, this board has a wealth of features including excellent on board "health monitoring" functions.  The on board Winbond chip does a nice job of keeping tabs on CPU Core temperature, voltages and fan speeds. 

The SY-6ICA also has an integrated audio codec for a quick software driven stereo sound fix.  For those of you that want high fidelity, 3D positional audio, this may not suffice.  However, if you just need some sort of decent sound and don't mind the small performance hit with the added processor overhead, this is basically a free bee.  Finally, the SY-6ICA has the ability to adjust processor speed in the BIOS.  It also has jumper adjustable core voltage tweaks, a welcome feature for those tough processor that like a little extra juice to really get moving.

Mechanically, things drop off a little for the SY-6ICA.  There are two rather significant annoyances with respect to the layout of this board.  First, the pin headers for the case led, power and control buttons, are somewhat out of reach.  As a matter of fact, we could barely get the ATX Power On Switch cable in our LiteON case, to reach it.  The reset switch wires were a total no go.  In addition, the ATX Power Supply connector is right smack dab in the way of where a large heat sink and fan cooler would protrude from the CPU Slot.  With this board you will need a fairly low profile cooler to fit in the area in front of the ATX Power Connector.  A retail Intel heat sink fits easily as does the Vantec P3-D5030.  With one of the larger Global Win coolers, for example, you could be out of luck.  Why Soyo?  Surely the layout engineer could have found a better location.

Installation and Setup With The SY-6ICA
Smooth sailing

Once we got the mechanicals in order, things moved along nicely.  Installation of the various INF files and ATA66 EIDE Controller Drivers, were crisp and clean.  Soyo packs in there standard suite of Symantec Software with the board including, Norton Ghost, Virtual Drive and Anti-Virus.  Nice touch Soyo.  In addition, they include Winbond's "Hardware Doctor" program for monitoring various vital signs within your PC.  Here is a snap of it in action.

This board was also fairly forgiving with respect to IRQ assignments and DMA resources.  We even loaded all 5 PCI slots up without a single conflict.  Soyo does give you the ability in the BIOS, to adjust IRQ designations to the PCI slots as well.

Well, there is really not much else to report in this section since things were uneventful, just the way we like it.

Let's hit the switch, shall we?
