Today we are using the latest high end motherboard from ASUS – The Rampage III Black Edition, which we reviewed late March.
Until we updated the bios to the latest version, the Kingston HyperX T1 12GB kit would not run faster than 1333mhz.
The bios correctly tuned the DRAM voltage to 1.65v (1.66v reading above), however we manually increased the QPI/DRAM core voltage to 1.35 for added stability.
Trying to force timings and latencies any tighter proved unsuccessful. We did notice that the tRAS setting was automatically detected by the ASUS bios as 24, rather than 27 noted by the XMP-1600 profile in CPU-z.
System validation is available over here
This Kingston HyperX T1 memory didn’t overclock particularly well, we did manage to increase speeds to around 1670mhz, but it made negligible difference to performance results. Extra voltage didn’t really help either. We would expect most people buying this specific memory kit to run with the XMP profiles enabled so it is how we will test it today.
