The other issue is AMD seems to have slacked off timings in an effort to appease people however its doing absolutely nothing but hurting performance. ( compare my screenshots and you will see TRC 63 1.94a, TRC 73 2.0 and that's what we can see without even digging )
Does the higher tRC change anything with Voltage use?
Because the FX & PII Need less v-Core with higher tRC
