Hi everyone i am going to get myself a new pc built very soon and had some questions regarding it.I am planning to get a non k i7 4770 and was wondering if i could run it 24x7 at 3.7/3.9 ghz by setting the multiplier or any other way,also i wanted to know if there is any kind of performance gain got by overclocking ram or running factory overclocked ram.
Another thing which i wanted to clear was whether the h87 motherboards support sli or not ,i know officially they don't but was wondering whether it worked on these h87 boards.
My planned configuration
i7 4770 non k
gtx 760 2gb
8gb ram 1600mhz
and i will get either of these motherboards
gigabyte h87-d3hp
gigabyte z87-d3hp
or
msi z87-g43
also i have seen battlefield 4's system requirements and it mentions 3gb vram so i was wondering if i will be able to game at 1080p effectively with 2gb gtx 760.Also guys are there any advantages of getting a z87 motherboard other than overclocked ram support,cpu overclocking which i won't be doing and official sli support.

Yes, it's usually possible to do that on a Z motherboard. Just set the multiplier manually to a fixed number within the range of Turbo Boost (you may still need to enable TB). That's normally 3.7GHz (4T) / 3.8GHz (3T) / 3.9GHz (1-2T) but on a motherboard with "Multicore Enhancement", it's often possible to run at at max 3.9GHz even under 4T loads.

PS: The advantage of a Z motherboard besides OCing is MultiCore Enhancement (more useful for non-K chips as mentioned above), and the ability to fine-tune voltages (eg, you may get away with say undervolting slightly -0.05v to -0.1v at just 3.9GHz) which would have the effect of running cooler & using less power. BF4 also doesn't require 3GB VRAM to run - it will run with less depending...

Well this seems very interesting and does overclocked ram has any distinct advantage or you need to overclock the cpu for that to also come into effect??

Intel's are much less dependent on high-speed RAM than AMD's. With rare exceptions (eg, F1 2012), there's very little difference in a lot of games:-

I think that pretty much sums it up when it comes to ram .I was wondering if the multi-core enhancements can be done on h87 boards as recently news came that board manufacturers were able to overclock on non z boards??

I'm honestly not sure as that can depend on individual brands & boards.

Thanks man guess i will check these boards individually ,as far as overclocked ram is concerned there won't be any gain in gaming or general purpose pc use like coding, watching videos etc ,i will go for stock speed ram only.
