A new DDR3 memory overclocking speed record was set at Computex Taipei trade-show last week. Using the latest microprocessor from Intel Corp. and the latest mainboard from Asrock, Nick Shih, an overclocking guru sponsored by the motherboard maker, has managed to boost the speed of a DDR3 memory module to whopping 4285.6MHz.

Using upcoming Asrock Z87M OC formula, engineering sample of Intel Core i7-4770K “Haswell” microprocessor and liquid nitrogen cooling, a team of overclockers led by Nick Shih managed to overclock Team Group’s Xtreem-LV-2666 memory module to unprecedented 4285.6MHz with CL14 31-31-50 2T latency settings. Previous DDR3 clock-rate record was 3900MHz with CL14 14-14-36 2T timings.

While setting a world memory frequency record is indisputably an achievement, it should be noted that Nick Shih and his team only managed to reach the unparalleled clock-rate only in single-channel mode, whereas modern microprocessors utilize dual-channel or even quad-channel memory sub-system. Therefore, there is no practical meaning in using 4.2GHz single-channel memory sub-system (with 34.28GB/s peak bandwidth) since it will be outperformed by dual-channel memory sub-system running at 2333MHz (with 37.3GB/s).

You are not correct. More memory bandwidth is require when adding more processors. AMD processors have poor efficiency and the processors have to be clocked much higher to just to compete against Intel Sandy Bridge. AMD APUs are a joke because there is not enough memory bandwidth for four CPU and 320 stream processors.

Just for a double whammy, AMD did an overclock by using their FX-8300 to clock it at 8 GHz. Only one core is clocked at that speed while the others are put in sleep mode.

So what Intel skip a beat that both Ivy Bridge and Haswell are both ticks. Intel always does a yo-yo tactic when they introduce new CPU models. AMD caught the yo-yo tactic when they introduce the Phenom processor.

And it resulted almost ZERO performance gain :///

Since the latency of the accesses doesn't improve significantly, nor will the bus turn around time, who the heck cares about this science project. Application performance is not simply improved by more bandwidth to memory, you need to cut latency and that didn't change. So this is a nice marketing piece but really who cares. They must be out on the portion of the curve where every increase in 100MHz gives you 0.05% improvement in some esoteric benchmark. Yawn.
