A bit late since this technically arrived a little ago, but nonetheless, I finally found a DDR Pentium III board! Featuring the VIA Apollo Pro 266 chipset, and support for both DDR SDRAM and SDR SDRAM, this board is pretty feature complete. It's even got the semi-ubiquitous Promise IDE RAID controller onboard.
A couple of things I have noticed in testing this board include the following:
- For a VIA chipset, this is remarkably stable, more-so than the VIA 694X motherboards I've tested.
- This board is wicked fast, yielding memory reads in the ~750MB/s range and writes in the ~420MB/s range with a PIII-S 1.26.
- The quirks this board had when reviewed by THG (no AGP Fast Write support) seem to have been remedied by the latest BIOS and performance notably increases upon upgrade to v1.5.
- Between DDR and SDR, the performance delta is measurable, but not quite as large as you'd at first guess. This makes sense, given the bandwidth-limited FSB of the PIII, but still, the fact that there's any performance difference just shows how nice these mature DDR chipsets could be.
Overall, then, this board is pretty weird, but nice and capable all the same.
-Live Long and Prosper-
