Which Memory to use ? i7-2700K and Gigabyte Mobo

[itakey]

I can use some help deciding on a good memory to fit into a new computer I'm building.

The current build includes:
i7-2700K CPU (Got a sick deal on it)
Gigabyte Z68X-UD3H-B3
Antec 302 Case
Hyper 212+ CPU Cooler

Looking I found these memory, but want to be sure it will fit since I've heard a lot of mobo's and CPU cooler's sometimes block out the 4th ram dimm slot. I'm probably going to run either 4GBX2=8GB, or 4GBX4=16GB.

Unsure if the Hyper 212+ cooler will block the slot or not with the mobo combo, so I've read that the CORSAIR Vengeance 8GB DDR3 1600 is worthy.

Any recommendations? Is regular voltage or low voltage ideal?
Here are some I found with good reviews:

Or a different memory? I'm up for all suggestions

1.5v is fine. Since there is only a $3 price spread, I'd just go with the low voltage Snipers, since arguably they use a better bin of chips.

Alternately, find some other DDR3-1600 that is 1.5v which cost even less (hot deals? rebates?). Your system won't care and you won't notice a performance difference.

Thanks Zap,

After looking at the picture, the sniper may have a taller heat sink than the Corsair Vengeance? Trying to keep it short for the Hyper 212+ cooler to clear.

EDIT
I just found the supported memory list

I just thought to hop over the mobo's site to see if they had a Memory compatibility list and they did, here is what I found as 4GB slots that are supported at 1600:

Kingston HyperX 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model KHX1600C9D3K4/16GX
at $99.99

Any major difference between these 2 ram's? I can see their timing is a bit different and voltage. One better than the next? The 12GB Kingston Hyper X is $54.99 after rebate which might be a nice sweet spot. Thoughts on that one with a timing of 9-9-9-27 with a Cas of 9 and a voltage of 1.65V versus the Ripsaw timing of 9-9-9-24-2N with a Cas of 9 and voltage at 1.5V?

1.65V too high? I like the Kingston since the heat sink looks shorter.

I went with this memory on the rig I just built for my son using the same mobo. Low profile, so no conflicts with the 212+.

Crucial Ballistix Sport 8GB (2x4GB) 240-pin DDR3 1600 Model#BLS2KIT4G3D1609DS1S00
$44.99

These are 1.5V sticks with 9-9-9-24 timings.

I'm planning on getting the Kingston Hyper X 16GB(4GBX4) but they are 1.65V. Some say those may cause issues with the Z68 board? They are listed as approved memory on the Gigabyte website for that board so I'm guessing they should be ok? Thoughts?

1.65v are fine just change your VCCIO upwards to keep the recommended <5% difference between the RAM and Vcore .

As long as that is ideal and won't make the system buggy i'm cool with that. Is it true that Z68's run better with only 3 of the 4 dimm slots full?

Sniper ram is nice and black which fits with your motherboard color scheme

Vengeance is the only ram set there that would really stick out too far for an aftermarket cooler....

The Kingston are 1.65V, and it's now 2012. I just wouldn't bother. Corsair, Crucial, and G.Skill all have 1600MHz CAS 9 1.5V sets that are not tall. I think most will clear a Hyper 212, but OTOH, the fancy heatspreaders are 100% styling, 0 substance.

G.Skill 1600: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231546
G.Skill 1866 (good price for 1866, though you don't need 1866): http://www.newegg.com/Product/Product.aspx?Item=N82E16820231550
Crucial: http://www.newegg.com/Product/Product.aspx?Item=N82E16820148544
Corsair: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233186

They offer the equivalents in 4x4GB sets, too. Don't sweat compatibility lists. 99% of the time it will work fine, and you can RMA for the other 1%. Worry about compatibility lists when building someone else a computer, where it being late due to such an easily solvable problem makes you look bad.

Also, minor performance details don't matter much, since you won't need to OC the RAM to OC the CPU, and RAM OC could very well net [small] negative results, depending on stable timings.

Great feedback, thank you!
I think i've decided to send back the Kingston Hyper X, and am going with the Corsair Vengeance but in white:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233199&Tpk=CML8GX3M2A1600C9W

I noticed that these have a voltage of 1.35V where the Black and Blue ones have a voltage of 1.5. Figured the lower voltage might be worthy if I ever want to overclock a bit later. Any reason why I shouldn't go with the white ones with the lower voltage? I'm assuming they are good, if not better than theother Corsair Vengeance at 1.5?

Memory shouldn't be this tough of a choice to make. Yes, theoretically 1.35v 1600 is "better" than 1.5v 1600, and definitely "better" than 1.65v of anything. However, you very likely will never notice (outside of benchmarks) any difference while sitting at your computer.

For socket 1155 I would choose memory in this order.

1) Any memory I already have on hand.

2) The cheaper memory.

3) The lower voltage memory.

4) The higher MHz memory.

5) The lower latency memory.

All makes perfect sense. If I only knew what I now know about memory 2 days ago my choice would have been easy. Appreciate the knowledge.
