Kingston claims the world record for DDR3 clock frequency with its HyperX T1 model.
On November 22nd, Corsair set the world record for DDR3 clock frequency at 3467 MHz using its Dominator GTX6. On December 3rd, Kingston broke that world record again at 3600 MHz, using a Kingston HyperX 1T memory stick.
Romanian overclocker Matose used an AMD FX-8150 processor and Asus ROG Crosshair V Formula motherboard to reach these extreme speeds with help from liquid nitrogen on both CPU and memory. The memory speed was overclocked by nearly twice the reference speed of DDR3 1866.

underclock your ram and let us know how it turns out
Thats not the same thing, other bottlenecks and limits of what is supported mean that anything past those levels doesnt do anything. You can get most any memory to go well beyond what you can use so goin for a record is mostly for fun, no practical use in a consumer pc. Not yet anyway. Lowering your clock tho will lower performance, upping it wont help unless you just have slower memory than what your system supports. And 3600 is way beyond that.
i mean on an outside of rendering applications that are ram heavy, is there even a need for faster memory?
keep in mind, i can see a need for faster cpu, faster gpu, faster hdd, faster ssd (not any more, not its price over speed they should focus on) but memory?

i would love to see some benchmarks. i know AMD apu love higher faster RAM speed.
Come on AMD, make HT faster and make better RAM!
Cheers!
The bottlenecks of performance in order are CPU -> RAM -> Disk. If your bottleneck is not your CPU for some 100% utilization computation, but instead CPU resources go unused because reading too / from memory is taking too long. RAM Frequency increases the rate the memory can be read, and how fast it can be read sequentially. So if you want to read out 500MB of ram to cpu and subtract 1 from every number in that chunk of RAM, if it isnt CPU bottlenecked, the ram speed is too low to load all that data fast enough. The CAS latency is how fast a random area of memory can be reached and read from, frequency is how fast data can be read from the entirety of the stick.
So more frequency means more bandwidth, lower CAS means faster random access. More frequency becomes more important as CPUs get faster because they can execute stuff faster, read and process instructions faster, etc.
So more bandwidth is important, but so is access time, which is why maximizing frequency while minimizing latency is important and a hard tradeoff.
Overclocking memory typically offers minimal benefits to performance compared to overclocking other components. Obviously, though, faster is always better, and even tiny boosts are welcome if they don't cost anything extra. A modest overclock that doesn't stress the RAM much is free and better than no overclock at all, even if its impact on performance is less than a 1% increase overall (referring to the RAM overclock, not counting the CPU overclock).
A setup like the one in this article is just for fun and bragging rights, though, and really has no purpose in a computer meant for real use. It is ridiculously expensive and would probably barely net you a 1-2% increase in overall system performance (referring to the RAM overclock, not counting the CPU overclock).
