Today we are using our favourite X79 board, the Asus Rampage IV Extreme. This motherboard is widely compatible with a great range of memory from various manufacturers and we have always achieved great results when overclocking.

The memory defaulted to 1,600mhz timings, which is a safe first post setting. By simply selecting the XMP profile, this is corrected after a reboot.

The memory defaulted to 1.65v via the ‘auto' setting on the Asus Rampage IV Extreme.

Above, some CPUz screenshots of the memory at default settings in Windows 7.

System validation is available here.

We couldn't get the system to post after selecting a 2,400mhz memory setting, so we were forced to clear the CMOS to reset the bios to default.

We overclock a lot of memory, so the first course of action to attempt a successful post at overclocked settings is to loosen the RAS to CAS delay settings. We changed from 11 to 12 and also loosened the RAS ACT time to 34 for added stability.

The system posted successfully and stability was achieved at these settings. System validation at 2,400mhz is available here.

We tried to push the memory further and did get a good post at 2,500mhz, although CAS Latency needed to be relaxed from 11 to 12. This had a mainly negative impact on the results, so we won't be using it for results today.
