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?"
Why? Because I've overc locked, so I'm faster than y'all!
Overclock your smartphone or tablet instead
For me, It's fun and I could care less what some dude did with liquid nitrogen.
First computer, I just used Asus Overclock and felt I got more for my money.
Second computer, I started fiddling with manual settings.
Third computer I pushed it until I couldn't get rid of the heat with air cooling.
Fourth and current computer, water cooled and running awesome (6 cores at 4.3 GHz).
Each time I felt the progress, it's like leveling your character, but the character is you, and the game is real life!
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?
Few people have any real need to sacrifice stability for a little more speed. Overclocking is pretty pointless for anyone with a modern CPU.
It used to mean windows would run faster, games would run faster, everything was FASTER MAN!!!!!111one.
But now overclocking for the at home folks is a case of hit a button in your bios, or in some cases a physical button on the motherboard, and it'll do some overclocking for you, automatically. As its become more automated, the news worthy stuff becomes more and more expensive to implement and show off, and so most things are less news worthy and so it appears "overclocking" happens less. In reality I'd expect it happens alot more, and maybe even when people aren't fully aware of what they are doing.
Also systems being so much faster now, generally provide the speed that users require of them, unless they are the kind of users to be pushing systems to overclock simply for the hell of it, like the guys who get in the news. However you don't see these guys then gaming and getting 200fps on these systems, or anything exciting like that anymore. Its simply overclocked, and shown it to be "stable" at said speed. No one ever goes "lets see how many FPS can we get outta this baby now!", its all become very much a concept thing rather than actually running systems at these speeds for any sensible amount of time.

Look, digital electronics are still subject to analog limitations. When you overclock, you squeeze the hysterisis curve, increasing the probability that your chip incorrectly interprets its the state of a particular bit as the opposite value. i.e. you get random data corruption. This is why you eventually start crashing randomly the more you overclock.
While overclocking a chip that has been conservatively binned simply to reduce manufacturing costs but is actually stable at higher clock rates is reasonable, trying to overclock past the design limits is pretty insane if you care at all about the data integrity. Also, you tend to burn out the electronics earlier than their expected life due to increased heat stress.
I never overclock.
Ten years ago, CPU and RAM speed were really big factors in how fast your PC felt. We've spent the last ten years optimising hell out of them, while still using 7200RPM spinning disks (if you're lucky). So, surprise surprise, today disk IO is what limits your PC's performance. Why overclock your RAM? It makes (almost) not difference to your IO speed.
I got a new laptop just over three years ago. It had a 2.4GHz processor. I got my next new laptop a few weeks ago. It has a... 2.5GHz processor. Clock speeds have become almost irrelevant. What makes the new sucker fly is the SSD. Unfortunately, there is no BIOS setting, however risky, to change from disk to SSD.

Not everyone overclocks to beat a record.
Hell, "overclock" a toaster if you have to. 2 second cold toast anyone? (the best toast)
But really, there are still plenty of things you can overclock to beat records, such as what iB1 mentioned up there, overclock a smartphone or tablet.
Overclock a Beagleboard, or a Raspberry Pi when it comes out, Arduinos. All these compact computers are pretty much sitting around waiting to be hit by the overclocking spirit.
No. Next question.
Seriously though, both Intel and AMD sell multiplier-unlocked CPUs as a feature, and the winners of tests in PC Pro magazine are overclocked by the system builder. You can even buy upgrade bundles pre-overclocked. My latest motherboard came with one-click overclocking software and can adjust the clock speed through a web page while playing a game. Liquid coolers are mainstream. Overclocking is definitely not dead.

"has the enthusiast passion for overclocking cooled off"
Not from my 5.0Ghz Core i7 2600k anyway -- The tools have become better, the mobo are generally better built and more tolerant to punishment (some have 2 Oz copper), the power rails are a LOT more controllable than before, and in general the IC companies that make the power ICs have progressed a lot too in that time, so you can overclock easier, quicker, get better results and in general, extract quite a bit more, without nitrogen.
And, I compile distros all day, to me going from 3.8Ghz max to 5.0Ghz stable (and quiet!) is awesome; make -j10 FTW !
In the days of the 300MHz Celeron, you could overclock it to 450MHz and gain 50% improvement. That extra 150MHz represented several hundred dollars straight to Intel, which you kept in your pocket by overclocking. These days, a few percent? It's just not worth the trouble any more.
Shutting down free speech with violence isn't fighting fascism. It IS fascism!
"...has the enthusiast passion for overclocking cooled off?"
That's like saying, "Do nerds no longer need a proxy for phallic measurement?" As long as there's still testosterone (even if it is minimal in some here) there'll still be people (men mostly) looking to say "We did it first!"

You just don't get the overclockers mentality.
Either is all part of the fun adding to the risk or you are getting the most out what you paid for and are still within stable limits.
I don't think many overclockers care about random data corruption unless they blue screen or they turn it off when they need stability.
I think CPU speed is less of an issue these days; eg Core2 onwards processors are generally "fast enough" for most users.
Compare the change in noticeable speed between a 386 and 486, or even Pentium vs Pentium 2 or 3, to today's Core2/Athlon vs Core i5/Phenom.
Most people don't notice the jump in CPU performance on modern processors.
The other traditional bottlenecks are rapidly disappearing too, eg a midrange Directx10 graphics card is good enough to play all but the most demanding games these days, and memory and disk speed and capacity are generally outpacing most people's demand.
People will still overclock for the challenge of it, but I think there's no tangible day-to-day benefit anymore.
As someone above mentioned, the real performance battle has moved to portable devices, eg how much performance can you get from a tablet or phone, given a fixed battery capacity?
When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is probably wrong.
Therefore, I rest my case.

"I compile distros all day. Yes, did you know that Slackware on average compiles 20% faster than Debian for 64 bit but if I overclock my Core i7 by raising power rail voltage and tweeking the quantum flux capacitor.... hello, where are you going..hello? Hey, come back, did I mention its a 2600K? Hello?"
Well let me dig up my test results spreadsheet from when I first got my 2500K CPU, times are in seconds to complete my task in Visual Studio 2010, first set of numbers is the system at stock clock, second set is overclocked at 5GHz, during my game development most of my day consists of building the game, loading the game and testing out changes or additions, therefore the reduction from doing that in 32s vs 21s is absolutely huge, even doing code changes that don't require a total rebuild I am waiting 3s less. It may not sound like a lot but when you are focused any time saved is very important, you can only be focused for so long.

I tend to underclock more often now, to reduce power consumption on my systems. Of course, I don't play any games on my systems, so I am almost never pushing the capabilities of the hardware.

For a small proportion of the population (but, possibly, a large proportion of slashdot-ers) a PC is not a platform for doing useful work or serving entertainment, it's a source of "fun" in its own right. In past decades the people who like to play with their computers would be out in the yard, covered in oil, fiddling with a junky old car, or tuning a valve radio. Now they get their satisfaction from squeezing the last few MHz out of their PCs - whether there is any need or use for those few extra cycles, is immaterial.
And for those with a more software bent, than a hardware leaning, there's always OSS - which serves a similar purpose.

While "low end" chips may be conservatively binned to reduce manufacturing costs, thats really not the whole story at all.
When the highest end chips can be clocked from 3.8 to 4.5ghz and higher using the stock cpu cooler, doesnt it make you wonder why Intel/AMD do not sell any 4.5ghz versions of these chips? Its because the OEM's fuck up case cooling every single time.
If Intel sold a 4.5ghz i7, Dell would still put it into a case with horrible venting and only a single fan that has been poorly placed, and then Intel would be footing the bill for loads of warranty replacements. The reason the i7 980X's cost so much isnt just because Intel was taking advantage of performance enthusiasts irrationality.. its because the Dell's of the world fuck up cooling every single time. The sandy bridge i7's perform nearly as well but run a lot cooler so can survive the harsh conditions the OEM is going to hamstring them into, and THAT is the main reason why they are so much cheaper than the 980X's.
