Clock Chipping iMacDVSE — #19

Kosmic, not all DVSEs have copper chips. Mine has aluminum I want to overclock mine to 500 Mhz. Would this be too much for my aluminum processor? I'm afraid it will over heat…

So my copper chip runs only 8 degrees cooler than your aluminum chip? As I said before, the copper wiring process was not designed for cooling reasons.

My guess is: There is enough variation in each individual chip that you would be hard pressed to find, in real life, the theoretical (cooling) advantage/disadvantage of either alum…

Yes, and why does my copper chip run hotter than some aluminum chips? It is not a fact that copper chips run cooler than aluminum chips. It isn't. Also, how the hell do you speed u…

Kozmik, you run a program called G3/G4 profiler form Powerlogix. You can set your L2 cache's speed a LOT higher. I have mine running at 222mhz (stock was 133) and it runs fine an…

Hey, let's all overclock our L2 caches and motherboards and while we're at it let's do our RAM chips and hard disks as well. P.S I overclocked my DVD drive to go at 24x

FYI: The Temperature sensor is IN the G3 chip, so you won't see any temp increase when boosting the cache speed, that doesn't mean that you are not running your cache too hot. The …

I increased the cache speed to 200MHz with that PowerLogix program, and it works beautifully! There's a noticeable speed difference in some things I do, also. I have a question, th…

My G4/400 was sitting at 199 mhz and I boosted it to 265.7 mhz that way and it runs for weeks at that speed without a problem. Of course, having two fans in the case helps. My wi…

How'd you OC a sawtooth? I thought that was impossible. ------------------ -Ruddigger ------------------ Have you had your gigaflop today?

It's done by switching resistors on the back of the cpu card. I did it by desoldering all the PLL resstors and soldering wire leads to the pads. Then I attatched 1/4 watt resistors…

Why not buy one of the iMac rack-mount kits, then get that studio display? Peace

They're not as nice as the G3 cases, and they don't boast extra space for my HD.

What makes dual-monitors work? — #2

You need 2 graphics cards for a dual-monitor setup. G4 towers come with one graphics card in a 2x AGP slot. Adding a second graphics card in one of the PCI slots and using that car…
