But is that really that much achievement? At shops are available ram sticks with clocks over 4000MHz at stock so i'm not sure if overclocking a bit over 5000MHz is something so special. Can someone enlighten me? What were stock clocks of these overclocked sticks?

Probably used the new TridentZ DDR4 4500MHz CL16. That would be my guess.

Insane speeds I remember when DDR 266 was the bees knees lol :P

Hi! The problem is that in system usage (games and applications) this higher speeds not give you a real increase of performance... since the most important talking about performance is the latency. Its just to records purposes.

It's already been mentioned but a also believe that breaking latency timings would be more of an achievement, especially for gaming where i suppose latency is far more important than 5000+Mhz speeds. Give me some 4000+ @ 9-9-9-27 and then i'd be impressed.

People seem to think that higher latency numbers in bios automatically means more latency in the real world. This isn't the case. 2666MHz with CAS14 vs 4000MHz CAS19, the 4000MHz one is actually lower latency, because the latency numbers means how many clock cycles that given latency is, and with higher frequency, the clock cycles are smaller units of time. The real time CAS latency of 2666MHz CAS14 is 5.25 nanoseconds, whereas 4000MHz CAS19 is 4.75 nanoseconds. I don't know how people keep missing that. Constantly hearing "oh its got high latency, so its crap" even though frequency is through the roof to offset it and beat the lower frequency set with a smaller amount of clock cycles for their latencies.

Haha, you must be a young'in then. I remember when 30-pin 60ns SIMMs were the bomb. And also installing faster L2 cache chips on the motherboard.

Every single time there's a thread about high speed DDR4 you get the same nonsense from some people. As you say, there's this flawed belief that because the timings are high the memory is slow. When you're pushing such incredibly high clock speeds, it more than negates the slower timings.
