Testing Method & Test Setup
It's the first time we are dealing with Micron's D9OBJ chips so we armed ourselves with an Ivy Bridge testing platform that
should allow our memory to show every last bit of its overclocking
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
1500MB instances of HCI Memtest that is considered one of the toughest memory

First of all we have noticed that unlike all recent Micron 2Gb D9 chips we tested previously those 4Gb D9
fall flat on their face using identical primary timings. Raising tRCD and tRP by one value
above tCL has noticeably improved the situation.
Secondly, you can see from the results chart, past 1.65
Volt scaling comes to an end. More juice only
increases the power consumption and heat. Usually Micron ICs are able to digest
higher voltages, but it looks like here it's not the case with 4Gb chips unfortunately.
Still with 1.65v we managed to push the kit all the way up to DDR3-1980 CL9 and
DDR3-2160 CL10 which is very good considering the form factor and the capacity of these memory modules.
Small design, Big performance!
