Which memory would be the best for this cpu?

Liberator408 · Jun 14, 2013

I've been looking at processors and ram for my new rig and was wondering whether tight timings or speed will be best in this situation.

Intel Core i7-3770K Ivy Bridge 3.5GHz (3.9GHz Turbo)

My processors Integrated Memory Controller Speed
Dual-channel DDR3 Memory Controller supports DDR3-1333 and DDR3-1600er memory

I know if you oc the processor it can use faster ram so if I overclock to say 4.0 - 4.5 mhz which ram would be better?

2 4 gb G.Skill ddr3 2133 sticks with a 9-11-10-28 timing and cas latency 9

or

2 4 gb G.skill ddr3 1866 sticks with a 9-10-9-28 timing and Cas latency 9

What models are those G.Skill RAM? 1866 is fine. What are your primary uses of the build? Most apps are not memory-sensitive.

Unless you are using the integrated graphics, the speed of the memory won't have too much of an impact, so just go with 1600 or 1866.

Stick with 1600. You won't notice the difference between 1600 and 1866. Mostly only noticeably in benchmarks.

1) For SB/IB while benchmarks show a large performance difference (1600->2400) in real life day-2-day usage you would be hard pressed to tell the difference. Zilch going 1600->1866.

2) For SB/IB The clock generators are independent for CPU/Ram. Input to both are 100 MHz. When OCing, You select the Multiplier for CPU,:
ie for an OC of 4.2, select CPU Multiplier of 42. For DDR3-1600 the multiplier is 4 (400 Mhz which equates to an effective of 800), for 1833 the multiplier would be 1833/4 of 4.5825. The 1600 would be runing in Synchronous mode while the 1833 would run in Asynchronous mode (PS use to be important, no longer much difference).

Side comment DDR3-1866 voids the Intel warrantee on a non OCed CPU, irrelavant for a OCed CPU as that voided the warrantee any way - LOLs.

Bottom Line - Unless you have one of the FEW software apps that can take advantage of the increased BW of higher speed ram stick with the spec, DDR3-1600 for IB (SB spec was DDR3-1333).

Thanks for putting in the time to answer in such a detailed way, you made my choice very clear.
