    All this renewed interest in corporations has us wanting our dot com parties back. They didn't mention the on-site oil changes. Interesting that the most valuable part of these companies is the lowest paying part: the QA lab. And the QA lab is still powered by 100Mbit ethernet.

    Then of course many of U thought runaway housing inflation would force these companies to think about moving elsewhere like, say, Pleasanton. Wrongo. Even with 4x more expensive rents than 2000, Silicon valley is still the king of corporate headquarters.

        According to the "Gnome sensors applet" on my laptop, idle temperature for the CPU/GPU are 61C. Running any type of GPU applications can push the temperature up to the high 80's . Above 91C, the system shuts down.

      Given that most processors shutdown to prevent thermal damage at around that temperature, I'd think not. The shtudown threshold of a P4 (one of the hotter running chips of late) was around 78C, I'd think that 80C is a bit high.

      That said, I do think that 40C is a pretty low bar to pass. Given that my P4 idles at around 48-50C, I'm surprised that they consider 40C to be an "average" test environment.

      • My Inspiron 8000 would pull over 80 deg C often, and would commonly be above 70 deg C using a fan-hack I downloaded for it. It could be the sensor is simply inaccurate and the fans and such were all adjusted to compensate when they shipped this out, or maybe it was closer to the CPU and GPU than a thermal sensor typically is.
    • They probably mean -40C, not +40C. Industrial temperature range is typically -40C to 100C. Commercial is 0C to 85C give or take a bit. I work in labs like this so it was interesting to check out their test setups. Nice to see they look as cluttered and disorganized as we do.

      That's ambient temperature. My laptop runs around 30C when ambient temperature is around 18-22C and 40C when ambient temperature is 32-35C, average load (it pushes 50C in 18-22C ambient at full load). I can reasonably assume it would run around 50C under average load if ambient was 40C, and 70C or higher under full load. Depending on the chip and laptop, that may be acceptable or it may be w

      40 degrees C is a sort-of standard for "elevated ambient" testing of electronics. The point of testing at higher temperatures is mostly to ensure that heat transfer out of the chips is sufficient at that temperature to keep them from overheating. The chips themselves will likely be running at much greater temperatures internally, but as long as the heat sinks are efficient enough, the chips shouldn't overheat.

      For consumer electronics, I guess the assumption is that if it's 40 degrees in your room, you're going to go find somewhere cooler to be, rather than sitting there with your PC blowing hot air on you.

      In other industries, the standards are different. Many products designed for use in an automobile are tested at 50-60 degrees, which is closer to the interior temperature of a car in full sun in a temperate climate.

        I'm sure that's a good assumption in many situations, but I've sat outside on my computer during the day a few (read: every friday since school started back up) times this year when the temp was over 110 F. I was out there when it was 117 F running along just fine for almost 20 minutes before my class opened

        Theres a difference between thermal analysis and environmental stress testing.
        • I may have overstated things a bit when I said that verifying heat transfer was the primary purpose of testing at elevated temperatures. It's an important thing to verify though. Depending on the level of analysis performed beforehand, you'll have greater or lesser confidence that the product won't overheat, but nothing beats actually sticking a thermometer in/on the device and checking.

          Of course in addition to that, you've got all sorts of other issues to look for - differential expansion causing component

        Automotive products that don't go in the cabin are tested at much higher temperatures than that. I work on microncontrollers for antilock brakes, and we test at 125C and -40C.

    • That's _ambient_. The GPU itself is going to be some deltaT above that.
      Since cooling solutions have an effective degC/W ratio, let's say deltaT = 20C. So testing at 27C ambient = 47C GPU, 40C ambient = 60C GPU.
  • I noticed their later drivers are seriously having problems in Windows. Linux seems fine to me, but Windows drivers' quality are getting worse and worse. I remember 8x.xx versions were pretty stable and had very few issues with them. NVIDIA needs to get its act together on their drivers. Good hardware, but bad software (Windows) these days.

      The last two releases of their Linux driver (100.14.11 and 100.14.19) haven't worked reliably for me; I kept getting system crashes and display corruption. Unfortunately, previous releases are incompatible with Xorg 1.4 and it'd be a pain to downgrade. (Since I don't really need 3D under Linux and I've got a 7300, I'm using Nouveau [freedesktop.org] - it's more stable and the 2D acceleration is much better than the old nv driver.)
