Pushing For Speed

With testing out of the way, I endeavored to see if these sticks had any headroom. I left the voltages and timings alone (at their XMP defaults) and started increasing the frequency divider until the system failed to boot. At that point, I backed it down to the last bootable configuration and did some proper stability testing. The T-Force DELTA TUF Gaming RGB easily reached 3700 MHz with all other settings unchanged. Unfortunately, that seems to be the hard limit for my sample sticks.



After testing to confirm that 3700 MHz was actually stable, I went back into the BIOS and started digging a little deeper to try to squeeze a little more out of the kit. I increased the DRAM voltage from 1.35 volts to 1.4 volts, and VCCSA and VCCIO both to 1.3 volts, but couldn't get any more out of the kit. I even tried loosening the timings significantly, but 3700 MHz was ultimately the best I could get. Still, 500 MHz is not a bad overclock, especially at reasonable voltages.
