To get to 466 you would have to change the data bus to either 66 or 133, and that is likely more work than just changing the processor multiplier. Has anyone changed the data bus s…

I think you can actually OC the G4s to beyond 500Mhz...as someone pees did on their Yikes and had no problems with it. The HD bug was somewhat obscure, but had to be addressed none…

This was the toughest mod I've done yet. You might blow the resisters by overheating them. I resolved that problem by using wire wrap soldered onto the resistor pads and then using…

What about overclocked a G4 500 to 550? I took a look at the motherboard and the processor isn't even ZIF anymore. Really bumbed me out.

Some managed to successfully OC their sawtooth to 550. The G4 CPU is on its own daughtercard, and is rumored that the pin-out for the daughtercard connectors of the single and the…

I once had a powerbook g3 300 boosted to 450mhz in my hands. It might seem extremely fast, but in fact is wasn't. the cache was too slow to keep up. The result were multiple crash…

so wait. Question. I have a copper G3 running at 333mhz. Im going to O/C it, but should I go to 400, or 433? If I went to 433 would my 512 k of cache not be fast enough, and I'…

The cache speed is relative to the clock speed... the cache speed is defined by a ratio, not a specific figure, so if you have a 400 MHz Mac with a cache running at 200 MHz, and ov…

I know that part Misha, but Micha (misha, micha, whatever hehe) said that the cache was too slow to keep up with the chip, which CAN happen. Thats what makes some athlons so easy …

you can always underclock your cache to less than 2:1 speed if necessary to achieve stability...

Are you sure you can underclock the backside cache all the time? I mean, what about durring startup when the rom is loaded and before any SCRI extentions? I thought that the cache …

Good point...I was just thinking 'bout Xlr8's utility to OC your cache and SP...which I guess could be altered after ROM loading...but then, there's that debate 'bout how ROM is lo…

Does anyone know how to disable the internal monitor on an iMac DV and drive the external one to something higher than 1024 x 768?

The graphics card can hardly be held responsible for its permanent position on the board - call the designers *$#@ing stupid, not the card. Cipher13

iMac DV -higer resolution? — #5

Perhaps, but the VRAM is not the reason the res is locked. I think Apple has crippled the chip, but try a software called "SwitchRes" to see if there are other settings available. …

iMac DV -higer resolution? — #6

The video card isn't the problem, IIRC, it's the monitor. The monitor only supports 1024x768. Now, if you were to remove the monitor, and replace it witha another 15" capable of …

going higher than 1024*768 on a 15" monitor that's 14.1 viewable? I use 1280*1024 on my 19" and think that's a bit too small to read comfortably.
