Several manufacturers use this IC and stock is 1.65 so fire away!!!

be carefull as performance for me was worse at 2200mhz than it was at 2133mhz,aida64 memory benchmark will show you,i couldnt get 2400mhz to boot either

are these the best well priced ram for a/my z77/ivy combo? board will be a maximus v gene, cpu a 3570k.. i was thinking about getting the patriot viper xtreme 1866cl9 (2x8gb) and not playing with it too much but saw these and their low voltages at stock.. 
I'm looking at the 4x4gb set, i'm probably not after going higher than 2000-2133 unless the information i read about not being much benefit of going higher is wrong but i do want to stay down at fairly tight timings (9 or better) and low volts..
not overclocked ram since the days of winbond BH-5, so all i've got to go on is what i read online.. not sure what is BS and what is gospel.. read something about dram volts over 1.5 not being good for IB? that's what put me off the patriot kits.. 1.55-1.65v
edit: oh, if it's pertinent, I plan to use a noctua D14 to keep my lady Ivy cool. Another reason i looked towards these sticks, no fitting worries with the samsungs, wasn't sure if the patriots would fit

It's fine to use 1.55-1.65v on ib,you'd usually need 1.55v for 2133mhz and it works fine with a d14 cooler,I have the same ram and cooler in my z68 board and there's tons of room

cheers wazza.. you've got the viper extreme? I think i might go for this 30nm samsung anyway as it looks like it'll be faster, just got to decide if i'll have this rig long enough for 32gb ram to become necessary - that was why i was looking at the vipers.. i tend to keep my rigs a long time

Given that 16Gb isn't even necessary now, I think 32Gb is a very long way off unless you run virtual machines.

im using 8gb samsung green on an asus x68 v pro and a gigabyte z77x up4 th
heres the speeds on the asus
1.55v dram for both boards

Just bought another 8Gb but I'm having issues getting it stable at 2000mhz. Even 1.55v wont get it stable at 10-11-11-28-2T-128 - any ideas?
I was running 8Gb comfortably at 9-10-10-25-1T-88 1.45v

Running 16Gb vs 8Gb increases the stress on the IMC. You'll have to increase other voltages that the IMC depends on, VCCIO(VTT) and/or VCCSA (IMC).

16gb would need between 1.55-1.65v dram voltage imo,cpu/vtt anywhere from stock 1.05v to 1.1v tho max safe is 1.2v

With the 15k revision of the Gigabyte UD5H two BIOS settings for Data Read and Data Write Slew Rate have been added, but there's no default values set (just a "-") and set to AUTO. Overclocking ram is massively more more stable after I set them manually to 3.
Anyone got an idea of recommended values for these settings?

Samsung IC 3 and 4 respectively on ASUS boards.

Thanks, I'm trying same settings on the gigbyte - all seems ok at the moment.
I'm still struggling to get 2000mhz stable with 16Gb but it's a lot closer than it was.

mem test one stick at a time then all four. This may be an IMC volts problem where you need a slight increase.

I slacked off all timings to 11,11,11,31 1T, 128 and it's stable for 2000mhz at 1.55v with IMC and VTT at default values. Looks like I need to fine tune from there, latency is a bit rubbish at the moment.
