Welcome to my post. I wanted to see what everybody's highest memory bandwidths achieved on socket 939 systems were.
I'm running an Opty 185@3.0ghz on a DFI Lanparty nF4 SLI-DR Expert UT with 2x1GB double-sided Mushkin DDR500 memory and a 7900GT. My FSB is at 250mhz and ram ratio is 1:1. Timings are 3-4-3-8 with all the bios memory settings set to AUTO. Also somehow with these settings my memory runs at a 1T command rate! My system never ran 1T stably before so that was very odd. 1T increased my bandwidth by 600MB/s at least.
My SiSoft 2007 memory test results are:
Int Buff'd iSSE2: 6163MB/s
Float Buff'd iSSE2: 6184MB/s
At 250mhz the max theoretical bandwidth is 8000MB/s so im at 77% efficiency. I would love to hit 80% efficiency but I lack the knowledge of all those memory timings and rates to tune my bios settings to be optimal.
Let me know how I stack up against the rest of your results! Please share all your settings and timings if possible so we can all tune our rigs.
