Test Setup
CPU : Intel I5 2500K Retail
CPU Cooler: Noctua U12P SE2
Motherboard : ASRock P67 Extreme6
RAM : G.Skill Ripjaws F3-12800CL8D-4GBRM
Video : Sparkle X460 Calibre 1GB
Power Supply : Cooler Master 850W
HDD : Seagate Barracuda 320GB 7200.10
Case: Cooler Master ATCS 840
During the tests, the CPU speed was set at 3.3GHz and Turbo was disabled in UEFI. Testing the memory at the stock settings occurred without problems, but when switching to the 1866Mhz step, I could not obtain stability by relaxing the memory timings, increasing the memory voltage to 1.65V or by increasing the VTT; at 11-15-15-30, the system was bootable, but after running HCI Memtest with 4 instances, errors started to occur after 30 minutes.
At the stock speed, the memory timings can be further tightened up, but it is needed to increase the memory voltage too (1.65V):
The pre-programmed timings and frequencies can be also found by using AIDA64:
