One press from the "Turbo" button overclocks the Core 2 Duo T7200 by 20%.
MSI GX-600 notebook reintroduces the turbo button

Earlier today MSI demonstrated the new GX600 gaming notebook at Computex 2007. The GX600 packs quite a few features into its welterweight 5.7lb package. But arguably the best feature on the GX600 is the Turbo Drive Engine technology.

When the GX600 is plugged in with AC power, the push of the turbo button automatically turns on Acceleration Mode. Acceleration Mode increases the processor’s front-side bus and raises the overall clock speed by 20%. A quick press of the button a second time returns the processor back to stock clock speeds. 

Intel’s recently announced Santa Rosa platform forms the base of the MSI GX600. The MSI GX600 features Intel’s PM965 Express chipset, a Core 2 Duo processor and 802.11n wireless networking technology.

A GeForce 8600M GT graphics card delivers DirectX 10 compatible graphics. MSI equips the GeForce 8600M GT mobile graphics with 512MB of video memory. MSI pairs the GeForce 8600M GT with a 15.4” WXGA widescreen display. The MSI GX600 also features HDMI and S-video outputs for external display connectivity.

Other notable features of the GX600 include an integrated 1.3 megapixel camera, Gigabit LAN, optional Bluetooth, PCMCIA Type II expansion and a separate NUMPAD on the keyboard.

Probably about 15 years ago I asked a guy what the "turbo" button on the computer did, and he told me that the 386 had an additional math co-processor on the MB that ran very hot, and the turbo button turned that on or off. Now that I have looked around for this, it seems he was feeding me a line of fooey, since I can't find that anywhere. Most places say the button turned on the cache, or increased the clock speed. Turning it off, they say, was to help old programs that relied on the processor speed for timing.

It was fooey. Pull up a chair and listen to this old geezer reminisce....

The original IBM PC, and subsequent IBM XT, ran 4.77MHz 8088 processors. They did have sockets for an additional math co-processor (the 8087), but they weren't hooked up to the turbo button. None of these chips ran very hot, and didn't have so much as a passive heatsink. They frequently had paper stickers on the top.

Most computer games at the time (this is the time of the Apple ][, TRS-80, Atari 400/800, Commodore Vic-20 / c64) were written with timing loops, as the hardware always had fixed-speed processors.

When XT "clones" hit the market around '83 or '84, they had the added value of higher speed processors - 6MHz, 8MHz, 10MHz... the machines with these faster chips were useless for playing the games (and some less frivolous business or scientific software which also relied on the timing), and thus the need emerged to have an easy way to slow the machine back down to the 4.77MHz speed - and thus the "turbo" button (and accompanying LED) was born.

As the PC platform matured with the IBM AT (286) clones, then the 386, 486, and Pentiums, the turbo button remained - although it was essentially useless. With the later machines' performance, turning turbo OFF did not restore the machine to a 4.77MHz PC/XT equivalent, it just slowed it down. It usually did not slow things down by changing the clock speed, but rather by inserting wait states or other cheap tricks to slow down performance. It was useless for many years before it began vanishing.

Its fun to reminisce. I'm only 22, 23 next month, and I remember the Turnbo button. Granted my era was more along the range of 386's and 486s. I had a case that showed you the speed at which you were running. It was either 33 or 66 I believe, don't quote me cause I was just a very young kid that was lucky enough to have his own PC, most of the time a hand me down from my dad. But ya for the most part the Turbo was a useless button except for the ones that slowed down to 4.77Mhz.

I'd like to see a button so I could play some of my old 16bit games though. For some reason they relied upon timing too.

What you need is the trusty app that allowed everyone to do just that: "MoSlo". It allowed me finish the current Ultima games on my speedy P90 way back when ever that was.

A quick search brought this link up:

I haven't tried that version but it claims to do the same thing.

You savior is here, and infinitely more useful than MoSlo used to be:


You can run those old games from the comfort of XP or Vista, dual core, and SLI to boot. And thanks to some filters, optional of course, those old games look like you remember them.

Couldn't one just run VMware server and play their games on a virtual machine running dos?

I currently run ms-dos 7.1 (win98se) in a virtual machine with no problems...

Now I haven't tried running any games under it, but i don't see why it couldn't be done.

I've seen even an old Compaq 486 without even a heat sink - true, the processor was really hot at touch. This was at the high time of the Pentium MMX processors
