DDR3 1600 (OC) RAM installation voltage problems.

My friend recently built a budget gaming computer for a bit over 500 dollars. There was, however, a problem with memory installation.
The motherboard supports 1600 (OC) RAM, so 1600MHz RAM should work. But by default, since it's 1600 (OC), it runs at 1333MHz. So we went into the BIOS and changed two things, the timings and the MHz. The MHz of the clock speed was changed to 1600 from 1333, and the timings were okay in the start, being 9-9-9-24 as advised by the company. The first thing I am concerned about is the command rate. By default, it was set to 1T, but I heard that 2T is better for stability. Which one should be used at 1600? Then comes the big problem of ours. We went into the BIOS and found a menu titled Memory over Voltage, and this gave options to change the voltage of the RAM while the menu with the clock speed and timings did not have those options. This gave a selection of anywhere from 1.2-1.9 volts, and 1.6 was the default that was already set. But, this went up in increments of tenths, so you could only change from 1.6 to 1.7, it got no more accurate than that. The recommended voltage for the RAM at 1600MHz is 1.65 volts. How could I keep it stable? Would 1.7 or 1.6 be the better choice? Could I go with 1.6 and lower the command rate to 2T and keep it stable? Is there a way to update the BIOS for a 1.65 option? Anything from a suggestion to a complete guide would help a lot, thanks.

Run it at 1.6v at 1600MHz 9-9-9-24-1t..The 1T command rate will not cause stability issues unless the RAM is not up to it but if it defaults out to 1T then run it at 1T..So, it should be 1600 MHz@1.6v 9-9-9-24-1T..DO NOT RUN IT AT 1.7V EVER !!!!!!

Thanks, I was thinking the same thing since there is no RAM that I can see anywhere that's ddr3 at 1.7v, the max is 1.65 but I think 1.6 is fine since a lot of RAM runs as low as 1.5 at ddr3.

Have you tried updating the BIOS?
What's the current version?
