Ram not running at advertised speed. How do I change it? [UNSOLVED]

Hello Tom's!

I own this RAM:
Ripjaws X running in 4x4 for 18gb

DDR3 2133 (PC3 17000)
Timing 11-11-11-30
Cas Latency 11
Voltage 1.5V – 1.6V

As you can see, it is advertised as running at 2133 MHZ. However, when I check in my BIOS, it ran at stock at 1600.

I have my CPU overclocked to 4.4 with 1.2V, and I've known my RAM hasn't been running at advertised speed since I overclocked it a while ago. I don't remember exactly what I changed, but I got it to run at 1866 somehow.

What settings do I change to get it to be 2133 MHZ, and also, how do I test stability? With a normal CPU stress test?

COMPUTER SETUP:
4690K
Gigabyte Z97X gaming 5
16gb Ripjaws (above link)
GTX 780
h100i
EVGA GS 650W

PICS:

I just went back and set it to 2133. How do I check stability? Also how do I check freq. in Windows? CPUZ says it is at 1066mhz...

I'd actually just return them but here goes.
Increase the memory multiplier to increase clock speed. To maintain stablity, you have to increase the voltage. You also have to increase the timings proportionally, diminishing your performance gains. Most you will get from it is higher power usage. The only feasible thing to do is to increase the clock rates within the range that the timings offer.
To test stabilty you can use software like Prime95 and and MemTest86 (which runs from boot).

I bought them a while ago, one set when i first built it, and one set later on for a total of 16gb.

I am not really understanding the timing changes? can you explain more?

Formatting a USB for Memest now. Will report back soon.

I hope so. It should have had 2133 MHz to start with so the timings may be incorrect too.

I will try that after Memtest is done. Should memtest take more than 25 mins? thats what it is at right now...

That's either incorrect or very bad marketing. Advertised memory speeds are always the same as what the BIOS shows these days. So it may apply but you don't get to see it.

Memtest can take pretty long. Good to see there are no errors, just keep going carefully. Memory breaks much faster under a bad overclock than a CPU or GPU.

it turned out to be unstable. When I started gaming I crashed every 5 mins. I set it back ti 1866 and it's fine now.

I think I'll just leave it. I don't want to go through the RMA process.
