Modding DA G4 533 for Cube...
Pending the transfer back of money from a deadbeat seller on ebay I was looking at one of the 533 7410s (unless that 1MB L3 comment is not a typo) that OWC has for sale. Only $28 right now and i'm tired of this 450Mhz 7400.
Anyways, just wanted to know about that rear window defogger method. Also if anyone has the resistor charts or recommendations on the speeds, they would be helpful. So far i've only found some on the Sawtooth modules. Gonna be my first leap into messing with resistors and such if I can get my money back and they still have these processors in stock. If not i'd still like any info or pointers.
My personal goal if I can get the CPU is to clock it to at least 600Mhz. Like to try for 650Mhz but, not sure if the Cube's stock heatsink could handle that even with my case fan.

Re: Modding DA G4 533 for Cube...
I'm betting it'll be fine with a fan. Heat won't be the problem, stability of the 533 MHz CPU clocked to 650 MHz will be.
But if I were you, and looking for an interesting CPU hack for the Cube, why not look around for a dual 533 module from a DA and cram that in for a dual 550 or even 600 Cube?
Before the Cube-specific upgrades came to market, the Sonnet Duet dual 500 upgrade was a rather popular (and pretty much problem-free) option for the Cube. Pity they don't sell them anymore.

Re: Modding DA G4 533 for Cube...
Too pricey for duals. I was just looking at the single 533 since I could find them cheap. Then theres also the single 466 CPUs. I know 7410s clock pretty well and that they are freaken sweet performers.

Re: Modding DA G4 533 for Cube...
Well I ordered it anyways. Now I have no money for anything for awhile unless I get that ebay money back soon (btw, never buy from PowerJack69). Time to get myself a 600Mhz Cube
.
Edit: Money got refunded!

Damn, you got a pretty sweet CPU, it will defeat my 900MHz 750FX even at 500MHz, but if I overclock my CPU to 1GHz, it may defeat yours even at 550MHz, it gives an 8FPS boots in UT2K4 demo (up to 25FPS) and a 100 MegaFlop boost in AltiVec Fractal Carbon.

Re: Modding DA G4 533 for Cube...
No way in hell will a 500MHz 7410 keep pace with a 900MHz G3 in anything other than AltiVec tasks, let alone beat it.

But he can run AltiVec Fractal Carbon in no-AltiVec mode, he even said that with the extra cache, it beats mine at 500MHz?

Re: Modding DA G4 533 for Cube...
Well from tests i've seen and done, i'd rather have the 7410 than the FX. Clocked at 600Mhz or higher, the 7410 holds its own or bests the FX. Won't beat the GX tho, no way.

...why would you cite an AltiVec benchmark with AltiVec turned off as a point of reference for anything other than pretty colors?

Re: Modding DA G4 533 for Cube...
I know it's for AltiVec only, but I might as well tell daugger reaserch to delete the no-AltiVec function.

Re: Modding DA G4 533 for Cube...
I'm not sure you'll be able to clock that 7410 to 600mhz, without also performing a hack to increase voltage to the daughtercard. I have the same 7410 in my Mystic G4, and it won't even boot at the 600mhz setting.
And by the way, there is no L3 cache, unless they've altered the card.
That aside, they do clock very well.

Re: Modding DA G4 533 for Cube...
BTW: It's currently at a 4:1 ratio ( 533:133 ).
You can easily get 5.5:1, which will run it at 550 in your Cube. I have the PLL resistor settings on my machine at home.
I can probably email them to you, tomorrow.

Re: Modding DA G4 533 for Cube...
Sweet, thanks hawk! 
Figure 600 was the max I could take things if it would boot. But still, 550 would be nice anyways since its a 7410. Bet it would make Halo playable. I remember some of the benches I saw with a 7410 and a R9200 awhile back in a PCI machine. Thing was getting better FPS than my 917/933 by over 5fps.
I know i'm gonna have to lower the L2 cache speed ratio with CPUD before I try this so I dont clock that too high right off the boot.

I don't know why you're showing me that since I was one of the first people to even mention comparing processors by running the Fractal Carbon with AltiVec off. Plus, we have already established repeatedly that I know far more about benchmarking and the legitimacy of various tests than you do.

You probably know this already, but just in case, you can use Powerlogix' Cache Control X software to adjust the speed of the L2 cache. You may not need to downclock it, just to go up to 550, tho. If you do reach 600, then probably.
Halo will still b*tch about needing a 6xxmhz G4 ( don't remember exactly, just that it's over 600 ), but it will be a bit less choppy. Hell, I used to play at 400mhz... that was a fun experience.
I remember a mod which adds 12volts to a Digital Audio 733 CPU when installing it into a Mystic or Sawtooth, and it makes me wonder if it would work for clocking a DA 533 to 600...
Because I'm convinced that the inability to boot past 550mhz is a voltage issue...
I'd try it, myself, but I don't think I can reconfigure my current daughtercard anymore

Re: Modding DA G4 533 for Cube...
Luckily Halo seems to be more GPU intensive than CPU intensive.
My old 933MHz QuickSilver ran the game splendidly.

Well a G4 550 or 600 would bridge the gap between my machines. Right now in terms of performance my Cube is just a tad slower than my Tower.
Not sure if that 12v mod would work here since that 733 CPU is a 7450, not a 7410. I checked before I bought and I found some ppl saying the board was designed differently. Plus it uses more power than the 7410 and with the Cube, i'd rather not press my luck too much since im running an ADC monitor. If I had one of those new Giga VRMs then of course i'd be looking at 7450s more seriously.
Think it could have just been your CPU. Thats what was always told back when I was clocking my ZIFs that not all CPUs are created equally. I just found a reference in the xlr8 database showing a 533 running at 600 but unable to boot 650.
Also just found this site: http://www.macinfo.de/tuning/tuning-g4saw.html
Hope the PLL settings and location are the same as with the DA chip. Thats been my trouble so far is finding notes on the DA chips so i'm guessing there are enough similarities between the 7400 and 7410 chips.
LoL, PBM400, I remember Halo on my iBook G3 900. It was quite playable, just a couple frames faster than my Tower, tho you haven't enjoyed it fully till you try it with some shaders on
