CPU speeds

[SignOfZeta]

My Mac SE (1987) had a big fan in it, but I think that was as much for the power supply, CRT, etc as it was for anything else. The Motorola 68000 in the thing runs bare in Genesis, Neo Geo, etc.

The Capcom CPS2, also 68000 powered, has a great big stupid loud fan in it, but as far as I know the only purpose is to fill the system with a pound of dust. People unhook the fans (so they can hear the game) and they don't melt or anything. I think the actual 68000 in it doesn't even have a heat sync.

Is it true that sounds in a game take up processing speed? I read that somewhere in a transcript of a presentation by Shigeru Miyamoto in 1999.

[TheOldMan]

Yes, it's true. Older systems use more processing power to manage sound, but even on an XBox 360 the cpu has to re-fill the sound buffers, so some processor time is used just for that.

Are you saying I don't need that liquid cooling mod for my TG16?
 

that's quite some steamengine there, punk.

Was there ANY consumer level CPU in 1987 that was capable of overheating in regular use? Most stuff back then produced more heat from voltage regulators than from processors. Heat sinks and fans were rare.

The only example I can think of, and it wasn't a CPU but a video circuit, was the C64... the VIC-II chip had to be heatsinked as it generated a lot of heat. The CPU, however, was always bare. I never really even saw heatsinks on CPUs until the rise of 100MHz 80486 processors.

Depends what C64 you look at.

Some heatsink more than just the VIC-II.   Some do the CPU as well, and some even do the SID.

the SID generates heat as well.

That whole f*cking thing generates (read: traps) heat really bad.


It is the leading cause of C64 failure.   Some have cardboard RF shielding that traps heat and fries the chips.  Retards.

Hey, that goth is going to grow up into the Monopoly Man (or Mr. Peanut), so spread a little love to the goths.

[vestcoat]

Traditional goth dorks in black are fine, but the brown-ies have been led astray.

I have that terrible feeling of déjà vu.

I'm the overcautious type i tend to buy tiny bga heatsinks for video card memory and use them to heatsink they shit outta everything. i will heatsink mosfets, voltage regulators, chipsets etc if a system is known to have heat issues. Hell, my dingoo a320 has a copper heat spreader on the cpu has its always overclocked (most likely only added weight to the system). I overclocked my genny to 10mhz and threw a heatsink on that as well (i now know thats overkill to).

[Marll]

How does one go about overclocking one of these older systems like a Genesis or TG? I've been overclocking PCs ever since a viable BIOS in a system allowed it, and tend to also heatsink or watercool in some fashion everything in a PC. I've always wondered if heatsinking and cooling older systems would have any benefit at all.

Also would OCing something like a Genesis make all the games run faster, such that the audio is all weird too?
