Can some one help me with voltages/ram timings

Hi, I'm pretty new to over clocking, and i need help to make my DDR3 1600 run at 1600 without making my system unstable. When i have set it to 1600 i got blue screens occasionally and yesterday while running a cache stress test in everest it cause me to blue screen in seconds. I have under clocked my ram to 1066 which it defaults to in bios (even tho its rated for 1600), then the blue screens stopped and i was able to stress my cache with no failure. When i had it running at 1600 my timings were 7-7-7-24 1t @ 1.64 volts (couldn't get to 1.65, only 1.64 or 1.66) which it is advertised to run at. So is this a hardware issue or should i have changed some other settings?

Thanks.

Try increasing the QPI/DRAM voltage a bit. The QPI/DRAM voltage should always try to be within .5v of the DRAM voltage.

put my qpi/dram to 1.65 and dram bus voltage to 1.64 and it failed the test. also idk if this matters but when i put it at 1600 it runs at 1603(801mhz).
Please help.

Well i set my timings at 8-8-8-24 and it is perfectly stable now. I have never really messed around with my voltages before so can some one please help me to get my ram to run at 7-7-7-24 without the stability issues?
