Memory Divider Issues on DFI Infinity RS482

[Statzere]

When attempting to overclock my 3000+ on my Infinity RS482, i've run into issues with memory dividers. My ram runs fine at the stock 1:1 ration at ddr 400, but I can't boot into Windows over ddr 367 when using a memory divider. I've tested my processor up to 2.6 GHz, and my FSB to over 300MHz, so those aren't bottlenecks. Does this sound like something a bios update might fix?

no. raise Max Asynch Latency and possibly Read Preamble

Increasing Asynch Latency and Read Preamble let me get memory run memory up to a 388Mhz FSB (with cpu multiplier set to 8x); however, when I raise the cpu multiplier to 9x, the system will not boot. I've tested the processor at 388Mhz FSB independatnly (with a lower memory divider) and it boots/runs windows just fine. I think i've probably reached the limits of my hardware.
