Has anyone tried the ADB hack on a Rev B motherboard yet? The site I got the hack from (http://www.bekkoame.ne.jp/~t-imai/imace2.html) said something about rev B not supporting it,…
This link ain't work! I can vaguely remember seeing the site before though and thinking about it. The Rev. A board is really similar to the Rev. B board apart from the changed grap…
I recently tried to overclock my Yikes G4 from 400 MHz to 450 MHz by reconfiguring the white jumper block. Once in a while it'll attempt to boot up, but most of the time it goes in…
take it to 500! believe it or not a few people have more succes at 500 than at 450! If you don't think it will go, heres food for thought. I just clocked my sawtooth 350 to 450!
-c…
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…
Some time ago I mentioned my scratched iMac monitor. Appears that replacing it costs $430. That's almost the price of a second hand 17" inch Studio Display. What should I do? Find …
First generation iMacs have 66MHz buses.
Second generation iMacs have 100MHz buses (that's 50% faster).
At least in iMacs, what does this exactly mean? Is this the speed at which…
even the admin double posts! ^_^
To my understanding, general bus speed is the speed which your CPU talks to the RAM. the PCI and AGP slots have their own bus running at their own…
33 + 33 + 33 = 99
33 + 33 = 66
gee i dunno, looks like 100 is approx. 33 percentum more than 66...
double-post? me? never!

50% more means this:
x'=1.5x (1.5, since it's 50% more than 100%). Therefore: x'=1.5*66 and x'=100
Don't worry, most people don't understand this anyway.
33+33=66
33+33+(1/2)*(33+33)=99
thus the 50% increase. The calculation is done from the 66Mhz Mobo point of view, not the 100Mhz one
btw, just out of curiosity, if a post is delet…
ok i am just plain stupid.
explain to me again how 100MHz is 50 percentum more than 66MHz
now if you mean it is 50% faster... well...
good lord, i pay no attention to such trivi…
If I may:
33/66 = 1/2
so
33/66 = 50/100
so
100 is about 50% MORE than 66,
since it is 34 more than 66.
BUT, 66 is about 33% LESS than 100.
It depends on your viewing angle...
I we…
I am not sure of this, but the product of bus width (in bytes per cycle) and the frequency (in Hz) should be equal to the bandwidth. So:
64 bit bus = 8 byte bus
8 byte * 66MHz = …
yes, it is 66.66 mhz. And the 100mhz buses are actually 99.99mhz. But who cares!?
The real question is, can we change the bus speed in our 1st gen iMacs.
Ca$h
actually, in theory, it's 66.666.....repeat indefinitely, while 100Mhz buses should be exactly 100Mhz.
Don't ask me why they use 100/3 multiples 'cuz I have no clue...
and you can…
Does the bus OC have to be done with soldering or is there some sort of utility that can solve the problem for you, perhaps something similar to the Powerlogix backside cache utili…
I have PC-100 SODIMMs in my iMac Rev D (now rev B ). Could that explain the frequent freezes which only appeared after I installed the RAM? Is it possible the bus can't catch up …
Timmy, as far as I'm aware of, to OC the iMac mobo, you'll have to do it through hardware, and it's not just simple jumpers either...I haven't read anything on it from Xlr8yourmac,…
