This review is from: Samsung Electronics Extreme Low Voltage 30nm UDIMM 8 Dual Channel Kit DDR3 1600 (PC3 12800) 240-Pin DDR3 SDRAM MV-3V4G3D/US (Personal Computers)
Using this RAM with a Sandy Bridge i7 2600K.
Initially installed one 8GB kit (2 x 4GB sticks). Overclocked to 2133MHz 10-10-10-28 1T completely stable at 1.45V DRAM.
I then added 2 more sticks a week later for the total of 16 gigs and 4 sticks, which made overclocking stability unsurprisingly more difficult to manage. I can do stable 2133 11-11-11-28 at 1.55V DRAM, but trying to go down to CAS latency 10 requires going to 1.6V+ DRAM. I have it *almost* stable (at least passes a few runs of Prime 95, but not 7 instances of MemTest from within Windows 7) at 10-11-11-28 2133MHz at 1.615V DRAM, but don't really want to go beyond that, as I undervolt (and overclock) my i7-2600K, and my VCORE offset is at -0.15V. By the way, raising VCORE and raising VTT (VCCIO) did not seem to make the RAM more stable. My default VTT was 1.076V, and I increased it to 1.104V, and if anything, I got more errors increasing it, though I have read that it helps with RAM overclock stability for some systems.
I can run all 4 sticks stable at 1866MHz 9-9-9-24 1T @ 1.45V DRAM.
Conclusion: very good RAM, no faults so far. Big bonus is that it's such low profile that if you have a heatsink with a fan that sticks out over one of the RAM slots (and I do with my ASRock Extreme 4 motherboard), you can still fill all 4 slots with RAM sticks easily!
