Hurrah!

The lesson here is that people who own a cool, overclockable GPU in a gaming laptop may want to overclock it. Goodness knows what came over them when they removed it, but at least they've seen sense now.

FWIW, the GM204 chip runs cool and is easy to overclock. I overclocked my 980M from 1,038 MHz (core), 1,253 MHz (RAM) to 1,228 MHz (core), 1,373 MHz (RAM) and received an 8% boost in my 3DMark scores. The GPU temperature didn't go above 70C either.

It makes a noticeable difference playing games at 3K, which is the native resolution of the panel.

For those who are unaware btw, if the chip gets too hot it'll simply downclock until it reaches a stable temperature. In some brands of laptop that happens at stock speeds, whereas others (such as the Clevo I have) have plenty of headroom. It's not the sort of thing that's going to lead to warranty repairs.

FWIW, the sort of laptops for which this is an issue (ie high-end gaming laptops) typically have graphics cards on MXM modules, they're designed to be upgradeable to the latest and greatest.

The *price* of those modules, however, means it's not something most owners will ever do...

The cheap and nasty Acer will throttle when it gets to 70C, overclocked or not.

The water outside here isn't frozen. I'm in the southeast of the UK, where we've had a generally mild, largely snowless winter - it's 8C as I write this, for example. Not that that matters, as most of us have central heating and the temperature indoors won't be anywhere near as cold as it is outside!

The 2nd-gen Maxwell chips are known to run cool and overclock well, be they laptop or desktop form (in fact, it's the same silicon - just with a few bits lopped off and a lower stock speed for mobile). A cynic would say they're removing overclocking as it'll impact on their plans to release slightly faster versions of the same chip later this year...

The 980M in my Clevo P650SG overclocks by 125MHz with ease - and it won't even hit 70C while playing games in that overclocked state either. When you're playing at 3K (there's also a 4K screen available), that extra 125MHz makes a noticeable difference.

Removal of overclocking from the drivers is irritating at best.

Manley's paper explains how the various figures were derived. The early figures are subject to a good deal of approximation, but if you leaf through the paper you'll see various sources have been used to compile the data. By the mid 1700s records are accurate enough that no approximation is needed. Although it's a far from perfect way of doing things, it's the best we have. The CET series is the world's longest monthly temperature record series, FWIW.

"Before 1671 intstrumental readings are few; accordingly all values before 1671 have been rounded to whole degrees C. Regular thermometer readings began again in 1672. "

There's been a marked trend here in the UK for people to have warmer and warmer houses. The thermostat in mine's set to 18C (64F), as it has been for the last 30 years. Meanwhile my friends' houses get warmer and warmer - up to 25C in some cases (77F). There's a perinneal struggle in the office at work too, with my preference for the temperature to be set to 18C, while the boss would rather have 25C. So we have a compromise of 22C, which is still warmer than the neighbouring IT classrooms (yes, I work in a school). Those classrooms are set to 19C or 20C.

I work in a school. We've been through the whole "every pupil gets a computer" phase and it was a disaster - we used eeepcs running Xandros and initially there were complaints about how crummy the programs were. (IE people expected Office, but they got OpenOffice instead).

Then after a few days the breakages started - minibooks left in bags, being dropped, screens smashed, drinks spilt on them etc. So that meant that teachers couldn't rely on everyone having one any more and the whole point of them was lost. They stopped being used and we ended up getting about 30% of them back after the year was out, the rest were damaged or lost. It was an absolute waste of money and it still goes on with other schools today (those who are foolish enough to give tablets to all their pupils, anyway!)

We still use desktop PCs running Windows and Office, as it's what the real world uses (for now, at least). We provide access via UAG to our network for staff and pupils to access their documents remotely.

Google Docs, OneDrive etc are blocked for pupils. Chromebooks are pointless from our point of view due to Google Docs being blocked and lack of intergration into a Windows domain. They also don't run the programs which pupils use in school (which include some digital textbooks, additional educational needs programs, maths programs, Photoshop etc). iPads are beyond useless for our needs, as it's a faff to create spreadsheets or word process on them. Yes, it can be done, but a real keyboard and a decent PC make it much more pleasant.

So, like most schools around this part of the UK, we have several IT rooms with desktops. We have a media suite running Premiere (having phased out Macs a few years ago), a music suite running Cubase and a DT suite running SolidWorks. We have a couple of hundred staff laptops and a couple of hundred curriculum laptops, safely locked away at night.

We are looking at at BYOD implementation, but the powers that be aren't overly keen to have teenagers running around with expensive laptops, tablets etc. And there's the whole network file access issue, we can't add the machines to the domain so they'd have to go through the somewhat clunky UAG system to access their files. There's also the line of who has responsibility to ensure the machines accessing our network are patched and up-to-date, as we don't have the resources to look after people's personal equipment.

All in all, there won't be much change in the school where I work for the foreseeable future: Office and Windows look like remaining the main platform for a while yet. It's the same in the other schools in the area, Chromebooks and the like are simply not useful to the way that schools work around here.
