I am looking at buying this memory
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233360

with this mother board
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131855

and this CPU
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115229

My question is this: The Memory is 1866mhz and the MB is 1866mhz(nonOC) but the CPU is listed with a Integrated Memory Controller Speed Support 4 channels DDR3 1600. I have been out of the loop for a bit so will this cause a problem? If need be will the memory under clock to 1600mhz?

Any help would be appreciated, I have not built a rig since my AMD 64 4800+ X2 and I am playing catch up.:rolleyes:
 
It'll run fine, you most likely won't notice a difference though whether you're running at 1866 or 1600.
 
just buy samsung 30nm ram and oc to 1866mhz

it cost like $40 for 8 gb
 
Pretty sure his board/cpu prefer quad channel 1.5v, so going 2x dual channels would break the quad channel spec.

Although I do believe a 3770k w/ its better memory controller beats the quad channel SB-E's and will cost the same. So why not opt for the better performance for the same amount of money? If you haven't purchased already, look into this route. It won't be a huge difference either way though, and if you do go with the 3770k, I believe you're going to want to use 1.35v dual memory.
 
Recently purchased G.Skill Ripjaws 9-9-9-24 1600 MHz 1.5v - two 8 GB sticks. Surprisingly to me, I have managed to easily OC that kit to 1800+ MHz keeping timings and voltage just the same! Previously I had Corsait Dominator Platinum 9-10-9-27 1866 MHz 1.5v (replaced it due to a new CPU heatsink incompatibility) This kit costs double price of G.Skill, and Dominator was unable to run at lower timings and overclocks just a little... Long live G.Skill!
 
IMO, just get a 2x8GB set of 1333 or 1600 RAM, since you're not going to notice a difference with anything clocked faster. Crucial Ballistix Sport 1600 (1.5V or 1.35V) is right around $85-86 shipped and is damn good RAM, for example.
 
Given that the price difference is ~20 bucks between decent-grade 1600 and 1833, the only justification you should be making is that the 1833 (or higher), not being a JEDEC standard, will likely contain better-binned chips.

As a few others have said, the speed difference will be unnoticeable.

But the 1833 Corsair is more likely to have chips with slower JEDEC binning than the 1600 Samsung, and I doubt that module makers bin as strictly as chip makers do, although experts have assured me that there's no correlation between chip maker binnings and actual overclockability.

as long as all 4 sticks are the same rated speeds and specs it will run in quad channel. You dont have to buy special packaged quad channel packs.
 
I asked in another thread but maybe there I'll get my answer quicker.
Would there be any difference betweed 2200Mhz and 1600Mhz in i.e. BF3 or BF4 when it's released?

Sandybridge doesn't really show any meaningful performance improvement in memory scaling past 1600mHz. Especially given what you are paying for DIMMs.

From what a number of reviews have concluded, there really isn't anything meaningful above 1333. ;)
 
I just prefer good old 1600 Mhz RAM with tight timings like 7-7-7-24 are really good but hard to come by. and even then you can OC most of them. on in benching can the frequency really make a difference.
