Raspberry Pi Gets a Turbo Mode to Take it To 1GHz

By - Source: Raspberry Pi | B 16 comments

And you won't void your warranty by enabling it!

Raspberry Pi has captured the minds of developers around the world. Despite the fact that it was designed for teaching kids the basics of computer science, the tiny $35 computer has found its way into the hearts of grown-up devs. Today brings good news to those who've spent their time overclocking and overvolting Raspberry Pi, warranty be damned.

The Raspberry Pi Foundation announced that the dinky computer has just been given a turbo mode that dynamically enables overclock and overvolt without affecting your warranty.

"We've been doing a lot of work to understand the impact of voltage and temperature on lifetime, and are now able to offer a 'turbo mode,' which dynamically enables overclock and overvolt under the control of a cpufreq driver, without affecting your warranty," Eben writes. "We are happy that the combination of only applying turbo when busy, and limiting turbo when the BCM2835′s internal temperature reaches 85°C, means there will be no measurable reduction in the lifetime of your Raspberry Pi."

According to Eben, the author of the post on the Raspberry Pi Foundation's blog, comparing the new image with 1GHz turbo enabled, against the previous image at 700MHz, nbench reports 52 percent faster on integer, 64 percent faster on floating point and 55 percent faster on memory. Eben writes that there are five overclock presets in raspi-config, with the highest running the ARM at 1GHz. However, the level of stable overclock you'll be able to achieve will depend on your own Raspberry Pi and the PSU you're using. To that end, the Foundation recommends using Quake 3 as a stress test to check stability.

    What do raspberry pi and Kickstarter have in common?

    They're two things I can't wait for people on tech sites to stop bringing up on a near-daily basis.

    My order keeps getting cancled. They took my money then refunded it 3 times in the past 6 months.

    too bad it only has 256MB RAM (makes browsing the web and doing other basic functions quite difficult)

    I ended up selling mine and will wait for a devide with at elast 1GB of memory.

    the PI isnt made to be an internet browser, it in fact can... but it's a learning tool for basic programming and other linux based applications. they're a lot of fun to play with and learn with!

    for it being a customized cellphone platform of sorts (S.o.C +size +price)

    cool beans

    Quake 3 as a stress test I like the way they think. Lets just hope we don't get a Q3DM problem while "stress testing"

    When I was at RPI, we [well not really me, since I wasn't a grad student and technically not invited, but I did tag along a couple of times] played Star Craft to stress test the networking lab :)

    I installed the new version with turbo boost at 1GHz, but it seems just as slow as before. Hopefully they will release the Android 4.0 port soon, because the demo videos looked very smooth. Android would make the Raspberry Pi much more functional than it currently is.

    Did you change the overclock preset after updating to the new version?

    You can see both how this is done here, as well as get an idea of the performance increase.

    Every article I read about the Raspberry Pi gets me more excited to get mine...
    I hate waiting

    I have the first Raspberry Pi released. It's a cool little toy, but it's fairly slow. Glad to see they're improving on an amazing idea.
