Is Overclocking Over?

MrSeb writes "Earlier this week, an ExtremeTech writer received a press release from a Romanian overclocking team that smashed a few overclocking records, including pushing Kingston's HyperX DDR3 memory to an incredible 3600MHz (at CL10). The Lab501 team did this, and their other record breakers, with the aid of liquid nitrogen which cooled the RAM down to a frosty -196C. That certainly qualifies as extreme, but is it news? Ten years ago, overclocking memory involved a certain amount of investigation, research, and risk, but in these days of super-fast RAM and manufacturer's warranties it seems a less intoxicating prospect. As it becomes increasingly difficult to justify what a person should overclock for, has the enthusiast passion for overclocking cooled off?"

      You'll save a lot more battery if you undervoltage your CPU. Eg. My Galaxy Nexus by default runs at 1350mV. I can run it perfectly fine on 1200mV, even overclocked to 1,4GHz. By my (possibly completely wrong) logic, the faster the CPU runs, the shorter time it spends in higher voltage states. Thus, overclocking and keeping the same voltage (or even undervoltage) actually saves energy.

      (Of course, underclocking also achieves the same since the voltage is lowered automatically. But then I've got a slower device rather than a faster device, while using more or less the same amount of juice.)

      Your logic is wrong.

      Every time a FET switches, it requires a certain number of electrons to move to or from the gate to create an electric field in the substrate to open or close a conducting pathway. This is a current flowing through a reistance and it dissipates power as heat. Assuming that the leakage current on the gate is very small compared to the switching current, the energy required to switch the FET (call it Es) is constant regardless of the clock speed. So the power dissipated by each FET (call it Pf) is:

      Pf = Es x fc

      where fc is the clock frequency in Hertz.

      Why do you suppose that frequency scaling is an effective way of saving power?

CM9 is unusable without the extra boost, and the overclock takes CM7 from somewhat laggy to silky smooth in most operations.

      That's total bullshit. Power consumption of a CMOS can somewhat be seen as this (incomplete formula to leave out device specific constants): Power consumption ~ Frequency * Capacitance * VCC. In other words, if you increase the frequency and VCC stays constant you're just going to burn more power for an almost irrelevant increase in performance.
      In fact I've read a lot more bullshit here but to address one more thing in specific: Most modern devices are made using CMOS technology or at the very least using FETs. A common misconception I see here is people assuming that CMOS devices use power while in a stable state. The fact is, they don't if they're well designed; The power being used is to charge the gates of the FETs. Once they're charged the only power use is to compensate for leakage currents from the FET gates to other parts of the substrate. If you don't believe me, build a small circuit using FETs (think something like a bunch of flip-flops), switch it a bit at a fairly high frequency. Stop the clock. Put a capacitor over your power supply. Then disconnect the circuit so its powered from the capacitor. It'll keep its state for weeks most likely.

      Actually, voltage matters substantially.

      The gate of a FET is effectively a capacitor. Even with the FET in the on state, if you keep increasing the gate voltage it'll still keep taking electrons. And like a capacitor, energy stored in a FET gate = 1/2*C*V^2. You also have source/drain and gate/drain (miller) capacitance - source/drain has to be discharged (another 1/2CV^2 loss) and the miller capacitance has to be discharged and then charged at the opposite polarity (a CV^2 loss).

      Overall, neglecting leakage current, power loss is proportional to frequency, but it's also proportional to voltage squared.

    From a gaming perspective (typically one of the big drivers of overclocking), a few factors that might argue "yes, it's over":

    1) For quite a few years now, PC games haven't been forcing the kind of upgrade cycle that they did over the previous 20 years. When Crysis appeared in 2007, it was a game that gave many people an "upgrade or don't play it choice". And after that... the industry retreated. Consoles were the primary development platforms at the time and few PC games pushed significantly past the capabilities of the consoles. Not only did we not see any games more demanding than Crysis, but the vast majority of PC games released were substantially less demanding. As a gamer, if you had a PC that could run Crysis well, you did not need an upgrade. This situation lasted 4 years.

    2) Performance has become about more than clock-speeds. The main advances in PC gaming technology over the last few years have come from successive versions of directx. You can't overclock a machine with a directx 9 graphics card so that it can "do" directx10. Same goes for dx10/11.

    3) As the entry barriers to PC gaming get lower, the average knowledge level of users fall. PC gaming is, in general, easier and more convenient than it has been at any time in the past. Pick up an $800 PC, grab Steam and off you go. If you just want to play games and are using an off-the-shelf PC from a big manufacturer, you don't need to worry about switching around graphics drivers, sorting out hardware conflicts or any of the other little niggles that used to make PC gaming such a "joy". You can even find cases where PC gaming is easier than console gaming; the PS3, with its incessant firmware updates and mandatory installs has taken us a long way from the "insert game and play" roots of console gaming. People who are new to PC gaming just won't be coming from the kind of mindset that even considers overclocking as something you might even remotely want to do.

    4) Among "old school" PC gamers, I think there's been a growing recognition that overclocking has its downsides as well. In an economic downturn, when money is tight, you don't necessarily want to go risking a huge reduction in the lifespan of your expensive toys.

    That said, there are a couple of factors that might argue the other way (closely connected to the earlier arguments):

    1) System requirements are finally on the move again. After years in stasis, 2011 has seen the release of a number of games with equivalent or higher requirements than Crysis. Bulletstorm started the trend, but Battlefield 3 and - to an even greater extent - Total War: Shogun 2 have really started to push the envelope on PC hardware. A lot of developers openly admit to being bored with console hardware. Even though they still get most of their sales from the consoles, they are using the PC to push beyond what they can achieve there, both to get their studio noticed and to get themselves ready for developing for the next round of console hardware.

    2) The downturn also means that people feeling a squeeze on their budgets may be looking to get as much bang for their buck in terms of performance as possible. If you think that your new, overclocked PC will last long enough that you will be able to afford a replacement when it does start to give out, then why not take the risk?
