With the Ahtlon 64 looming in the horizon, it looks like the Socket-A platform is on its last lap. Even so, most chipset vendors are giving their full support to Socket-A and the three major AMD motherboard chipset manufactures have all released their latest incarnations. Will they be the last to support Socket-A? That would be difficult to foresee since the Ahtlon XP has an impressive CPU line-up and the platform itself could easily last through the next year.

One of the recent entrants was NVIDIA’s nForce2 Ultra 400, which is slowly replacing the older motherboards bearing the original nForce2 SPP. Good thing that the nForce2 Ultra 400 is just a higher yield version of the original nForce2 SPP with the same ball/pin count, but on a newer packaging; this makes easy transitioning for motherboard vendors to integrate the chipset on their existing nForce2 motherboards. The nForce2 Ultra 400 was validated to operate at FSB400 and was also marketed to have better overclocking potential. However, we found out through our Soltek SL-75FRN2-L motherboard review that NVIDIA did not work close enough with the motherboard vendors, which resulted in huge RAM incompatibility problems due to timing issues. Only particular RAM modules synced well with the new chipset and helped us complete our benchmark suite. The problem seems to originate from the BIOS which was not properly optimized for the new chipset. We certainly hope that this will be an issue of the past as time goes on and with manufacturers updating their BIOS consistently.

MSI is just one of the many nForce2 motherboard vendors that has also moved forward with the new nForce2 Ultra 400 chipset variants and has completely phased out its older models based on the initial nForce2 SPP. The new motherboards sporting the nForce2 Ultra 400 are known as the MSI K7N2 Delta series with two models: the K7N2 Delta-L (nForce2 Ultra 400 + MCP2) and K7N2 Delta-ILSR (nForce2 Ultra 400 + MCP2-T). If you recalled the timeline during the original nForce2 SPP, MSI was actively marketing theirs as an affordable and simple nForce2 solution via the K7N2-L, whereas the IGP version was decked to the brim with features.

With the nForce2 Ultra 400 this time around, MSI is actively pursuing the feature-hungry enthusiasts and overclockers who would normally hunt for high-end boards with extra overclocking headroom. Since the new nForce2 Ultra 400 is known to give power users the overclockability they need, MSI pumped the K7N2 Delta-ILSR with more on-board features. Check out the specifications below and go over to the next few pages to see how it compares with the recently reviewed Soltek SL-75FRN2.
