Until AMD dramatically lowers its Athlon 64 prices or offers lower speed grades, the Socket A platform will remain quite popular among enthusiasts looking for the best bang for their buck. But what chipset will enthusiasts flock to for their Socket A needs? For some time, NVIDIA's nForce2 has been the Socket A chipset to have. However, the nForce2 is getting a little long in the tooth, and its lack of integrated Serial ATA support becomes more noticeable with each passing day.
The KT600, VIA's latest Socket A chipset, just happens to have integrated south bridge Serial ATA. But that's not all. The KT600 chipset officially supports a 400MHz front-side bus and features a tweaked memory controller that promises to wring every last drop of performance from its single memory channel. KT600 boards are making their way onto the market, and we've gathered eight of them for a massive mobo round-up. Just to keep things spicy, we've also thrown an nForce2 Ultra 400 board into the mix to see how VIA's latest Socket A creation stacks up against the well-entrenched competition.
Can VIA's KT600 run with or even beat NVIDIA's venerable nForce2? Which KT600 board is right for you? Read on as we compare boards from ABIT, ASUS, AZZA, EPoX, FIC, MSI, SOLTEK, and SOYO to find out.
VIA's KT600 chipset isn't a radical departure from the KT400A, but VIA has managed a nip here and a tuck there to improve performance and to offer more features. The KT600 north bridge is primarily responsible for improved performance, while the chipset's VT8237 south bridge has all the new features. Before we cover all that's new and interesting in the KT600, let's see how it's all laid out in VIA's lovely block diagram:
The KT600 block diagram nicely segments different elements of the KT600, which makes the chipset a lot easier for me to explain. Here are some of the highlights, starting from the top.
Another often-overlooked benefit of single-channel memory controllers is how easy it is to expand a system's existing memory configurationDIMMs can be added one at a time rather than in pairs.
Unfortunately, V-RAID only works with Serial ATA drive connected to the VT8237 south bridge; "parallel" ATA RAID isn't supported. Because V-RAID only supports Serial ATA drives, RAID 0+1 support is limited to KT600 boards that expose the VT8237's extra two Serial ATA ports via an auxiliary PHY chip.
