Blue and White G3!!

With overclocking the G3 300, go straight to 400Mhz. All the B&W 300s I've come across (about six now) all clock straight up to this speed.

Ahh... I remember playing UT on the 400MHz/rev A back in the day. And the quake3 demo. Its a solid machine. Except mine where I burned out the firewire hardware about a year ago. It crashed hard. The crash log wrote directly to the screen in command line style. Didn't make it to the log.

 
The G3 300, even overclocked, is still gonna give you a speed penalty compared to any higher speed G3 because it only has 512k of L2 compared to 1 meg on the rest. I'm pretty sure the beige G3 300 was quicker then the B&W 300 due to it having a larger L2.

 
^^yeah, the larger cache made a fair bit of difference. And another thing, Rev 1 motherboard support for 256MB RAM sticks is (in my experience, your milleage may vary) horrendous. I've tried a large number of variations, 256 meg sticks never worked no matter what sort I tried. 128 was the highest I could get working.

 
Redid the paste with AS5, currently got her running at 400. Someone wants to give me $50 for it though...I dunno whether to keep it or sell it and buy more 68k Macs. It is nice to have a decent marathon machine again. TBH, though, I enjoy trading Macs for other Macs I've never had almost as much as actually OWNING them. lol.

 
Don't mean to jack your thread, but I have two 350mhz b/w, with a mix of pc100/133 ram, so a 50mhz overclock is very safe even without extra cooling and a 100mhz overclock is doable with extra cooling? How do I test them?

 
The easiest way to test them is probably to leave them running something intensive like SETI@home for 24 hours. If they are still chugging along happily after that then it's a stable overclock. The only extra cooling I've ever used it is apply some thermal paste and put in a PCI slot cooling fan. The G3's don't run very hot so overclocking won't turn them into a toaster necessitating liquid nitrogen [;)] ]'>

$50 is at least half the price of an AGP G4 - faster bus, faster and cheaper upgrades, faster IDE. And a 6100 with a G3 and HPV card in it makes a pretty snappy Marathon machine :) Just my thoughts.

 
Well, I ended up selling this for $45. I used that to buy me another Quadra 840AV. I missed my last one but this one is hopefully in a little better shape when it arrives. What I'd really like to do is pimp my IIsi a little. Has anyone tried changing the clock on this to 25 Mhz (It's just a IIci in a different box) or adding an acclerated Quickdraw Card to one? I'd giggle if I could play Marathon 2 on this little guy. I have played M1 and M2 on it in 8 bit color at like 240x320 but it obviously isn't super playable. I feel like a clock boost and some color quickdraw acceleration might let that happen. On the other hand, I've run Marathon on it with MacsBug recording A-Traps, and I really don't see to many QuickDraw calls. Like, instead of calling things like _DrawRect or RgnRect or _Line, Bungie just wrote their own code to do this. :( Grrr.

That's because it would crawl if it did, it doesn't need the clipping model provided by QuickDraw.

QuickDraw implements a 2d graphics model, Marathon was rather 3d.
