I really am quite stunned that the ram I have can manage such speeds and timings. I was going to get some new 2133 rated ram that was three times the price of this cheap stuff, but if this cheap stuff can manage 2218Mhz at CL7, I have to wonder if it is even worth it wasting money on "high speed" ram anymore - or am I missing something?
I bit the bullet and purchased new RAM because the 2x2GB just wasn't enough for me anymore.
Since my last G.Skill memory overclocked so well, I thought I'd stick with G.Skill and see how their newer memory goes. Always being budget minded, I grabbed 2x G.Skill Ripjaws X F3-12800CL9D-8GBXL (2x4GB) kits, for a total of 16GB (4x4GB) of memory.
For the first benchmark, I installed the ram in no time and loaded the stock XMP1.2 profile, which set the ram to 1600Mhz CL9-9-9-24-2T - following are the stock speed results:
Memory-Copy: 23614 MByte/sec
Memory-Read: 20524 MByte/sec
Memory-Write: 22901 MByte/sec
Reached memory Score: 21.71GB/sec
Memory Timings: CL9-9-9-24-2T
Memory Frequency: 800Mhz (1600Mhz)
Then I spent the next hour trying to achieve the highest overclock I could, and not matter how high I increasing dram voltage or how loose I set the timings, I could not boot at anything faster then 1866Mhz CL10-10-10-30-1T - following are the overclocked results:
Memory-Copy: 26107 MByte/sec
Memory-Read: 22896 MByte/sec
Memory-Write: 23610 MByte/sec
Memory-Latency: 51.6 ns
Reached memory Score: 23.25GB/sec
Memory Timings: CL10-10-10-30-1T
Memory Frequency: 934Mhz (1868Mhz)

I have to say I'm a little let down tbh - this new memory is slower across the board then my older G.Skill Trident memory, and it has very poor overclocking potential compared to the G.Skill Trident as well. Just the fact that I couldn't even boot with this new memory at 2133Mhz at any timing or dram voltage shows just how poor the overclocking potential of this memory really is.
BUT, and it is a fairly big BUT - while this memory doesn't overclock well, it is still fast memory. This memory is no slouch by any means, and it can run 1600Mhz @ CL9-9-9-1T or 1866Mhz @ CL10-10-10-1T - making it ideal for anyone building a fast rig for gaming or editing.
The other important thing to point out is that this is low budget memory - you can buy 16GB of this stuff for only $88.00 AUD - which is pretty good
