Voltage/Latency scaling tests
Looking at the scaling curves with different latencies we see that only in the case of CL12 there is linear scaling showing big frequency increases when increasing the voltage. Testing the memory with CL13 as well as CL14 also shows that the memory responds positively to increased voltages. When looking at the CL13 curve the frequency bump between 1.35V and 1.5V is smaller than from 1.2V to 1.35V, which might already be an indicator for what we’re going to see with even higher latencies. Nevertheless CL14 is proving different, since in this case this kit scales best when changing the voltage from 1.35V to 1.5V. Arriving at the higher latencies we now see that testing CL15, CL16 and CL17 shows that voltages higher than 1.35V don’t have an effect on the frequency anymore.
