G.SKILL Ripjaws Z Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory

I am planning on buying these for my first build and would like to know what the performance difference will be between these and a set of 16gb 1600?

Thank you in advance to everyone is this wonderful community of people helping eachother out!!

RAM speed comparison - We're looking at a less than 2% difference from the fastest to the slowest. So its easy to see what is worth : )

Are you planning on using a RAM disk or running virtual machines? If the answer to either of those is "no", then you'll never see a difference between 1600 and 2133.

1600 really IS the sweet spot. Anything above that is exceedingly expensive for no real return on performance.

I do not know the answer to either of those questions so i guess it would be i dont know could you elaborate?

It means you won't see noticeably better performance in real-life applications by going with faster RAM.

Sorry im kinda out of it yes i do plan on using virtual machines Mac os x and ubuntu probably not all at the same time tho
 

Get it. Why not.

But there is a small benefit from that speed on Intel CPU's.
 

I'm pretty sure the Mac doesn't allow >DDR3-1600 (if not DDR3-1333) and the BIOS is locked-out, so I assume this is a Hackintosh. Unless you have an IB CPU I really don't recommend >DDR-1866 (DDR3-2133 max) on the SB and even then the gains are very VERY minimal especially in ANY form of Virtual Machine. I'd be more interested in 'more' GB than slightly 'faster' frequency with added burden of instability. So IMO DDR3-1600.

Q - What CPU?
Q - What MOBO?
 
The i5-2500K is "DDR3-1066/1333" so correct unless the BIOS allows for access to 'DRAM Frequency' or 'Memory Multiplier' than anything >DDR3-1333 is a waste and quite often a problem running so far below Rated Frequency with such a high Rated Frequency. Simply said DDR3-2133 will run like crap. The 'FSB Ratio' doesn't apply to newer CPU's. Also, IF the chipset is not P67, Z68 or Z77 then you cannot OC the CPU.

The BIOS however 'should' read the CAS correctly so DDR3-1333 CAS 7/8 is indeed faster than DDR3-1333 CAS 9/10.
