Right now, you are overclocking your RAM and that may be limiting your CPU overclock.
At 3.6 GHz, your FSB should be around or just under 300 MHz. Depending on what your BIOS calls it, lower your RAM clock to twice your FSB or around 600 MHz. This will give you a CPUZ CPU:DRAM ratio of 1:1.
Then you can see if you can get your FSB higher.
Overclocking RAM really does not help improve performance that much.http://www.tomshardware.com/forum/251715-29-ratio-myth
With the lower RAM clock, you should be able to lower your RAM timings.
