While we were doing some tests on the Z68 platform, we were interested in finding out how far can we lower the CAS latency of ram we have on hand. Using the Gigabyte Z68X-UD7-B3 board, we increase the DIMM voltage to 1.65v and that is all we did.
We managed to boot up at CAS 5 DDR3-1600. Although it is at a low latency, the bandwidth isn’t as good as the same modules running at C9-9-9-27 2T DDR3-2133. Below is a screen shot of the ram model Kingston KHX2133C9AD3X2K2_4GX running at CAS 5 DDR3-1600.
