Do you all think I might be having the same problem then?

My motherboard is a Giga P35-S3L, and my 2x1gb ballistix tracer 8500 will run at 1066mh 5-5-5-15 but will NOT let me tighten the timings no matter what volts I use. I can however get (just) upto 1100mhz @ 5-5-5-15 stable but no further.

Is it the board thats the problem?
