Testing Method & Test Setup

Knowing about Hynix CFR's capabilities from recent reviews, we armed ourselves with an Ivy Bridge testing platform that should allow our memory to show every last bit of its overclocking potential.
To make sure that our figures represent the sort of stability safe to use ever day, we are going to run each setting until we get a 150% pass of eight 750MB instances of HCI Memtest that is considered one of the toughest memory stress-tests around.

Motherboard ASUS Maximus V Gene (BIOS 1204)
CPU Intel Core i7-3770K @ 4.0 GHz
Graphic card ASUS GTX 580
Memory AVEXIR Core Series AVD3U28001204G-4CI
HDD Intel SSD 330 120 GB
PSU Seasonic Platinum 1000 Watts
OS Windows 7, 64 bit SP1


Our processor's IMC isn't HCI Memtest stable above 1'330 MHz (DDR3-2660) on the memory. Therefore we stopped the testing at 1'330 MHz.

As you can see the kit has some issues with voltages above 1.65v. We reckon - based on our experience with memory modules - that limited voltage scaling is caused by an imperfect PCB design.
If you take a look at the other kits we tested, which are also based on CFR chips, then you can see that the ones used here are way above average. There is some serious binning going on behind the curtain.
Unfortunately due to processor limitation we couldn't show the real potential of this kit. With a better IMC, this memory kit would fly at CL11 and CL12. Below we attached a screenshot, showing the memory frequency world record we set 80 days ago with this memory kit and some cold on both processor and memory.
