    Core temps during IBT are max 78, and max 40 at idle. How can I measure core voltage? Here´s the schreenshot of MaxxMEM˛

    CPU-Z shows vcore in CPU tab, other software loke HWMonitor (CPUID) can be used.

    Cpu-z, EasyTune6, HWMonitor and other programs will display your cpu voltage.
    The voltage reading will change depending on the load on your system.

    With good cpu heatsink, case cooling and reasonable room temperatures, IBT or LinX maximum temperatures are usually in the low to mid 60 (C) degree range.

    Look at your earlier screen-shot and you will see "Core Voltage" in the CPU tab of cpu-z.

    Memory bendwidth good, latency is a bit high but expected with tRD 8.

    tRFC is set to Auto. On idle cpu-z shows vcore 1.328-1.344V (mostly 1.344V) core temps are 38-42. When running IBT, cpu-z shows vcore 1.328, 1.312, 1296V. (mostly 1.296V) core temps are max 78. Due to IBT recent test failure on high stress level, I´ve raised cpu vcore another bit so here are the results and settings:

    Concerning Overclocking Sapphire HD 5670 512mb. GDDR5 I didn´t come up with anything on forums, only how to OC it with Catalyst, and I did it. If you want I can run some benchmarks, just tell me what program to use.
