Outstanding overclocking (especially FSB) on that MSI NF250 board: This late 3200+ achieved a new overclocking record on the K8N Neo Platinum at 246FSB, at the stock 10X multiplier and default voltage. This 23% overclock at stock multiplier is more like those that we are accustomed to seeing on Pentium 4. Dropping the multiplier, the highest FSB overclock that we could achieve was the BIOS limit of 300. We fully expect that the K8N can go much higher on FSB, but Clock Gen for the nForce3-150 from www.cpuid.com only partially works on the 250 chipset. The FSB portion of Clock Gen does not function correctly yet on the updated 250, so the BIOS limit is the current FSB limit. We were also able to run OCZ DDR4400EL at a 1:1 ratio at a FSB of 270x9, or DDR540, which is near the limit of this CPU on this board. We tried to lower the ratio to 8, but we still could not achieve 1:1 memory performance at any speed higher than DDR540, as the board would automatically reset to stock speed if we selected a 1:1 setting above 270. Perhaps the overclock protection on this board needs to be a little less aggressive, because this memory is capable of performance at even higher speeds. HyperTransport could be maintained at the 4X (800) setting up to a 260 to 265 FSB. Above this point to the BIOS maximum of 300FSB, we needed a 3X HT setting. There is clearly additional headroom with the higher HT of the 250 chipset, and it is likely that we can reach much higher FSB settings with a greater range of BIOS settings or a Clock Gen that fully supports the nF3-250 chipset. EDIT: So a 3200+ overclocked to more than 3700+ at default voltage. Doug
