But still no quad... As I was browsing thru the geekbench database the dualcore 2ghz or 2,3ghz would not be powerfull enough... I plan on big upgrades on the MDD and i am pretty sure to say it would beat all the G5 macs except the quad. Here is the highest MDD even with the original 7455 and its pretty high: https://browser.geekbench.com/geekbench2/2664246 So I plan a higher frequency than that, higher bus frequency, likely the same ram and sata HDD and SSD(with a bootable pb3214 pci-x card) so maybe even higher score than that.
That run is glitched.
This is an actual overclocked stock MDD: https://browser.geekbench.com/geekbench2/2665695
I think maybe you can manage 2000 if you overclock 7457 to 2GHz and the system bus also.

@LightBulbFun got 1,055 on a single 2 GHz 7448.


If we naively assume a dual 2 GHz 7448 will score twice as high, that'll be be 2,110.

As previous poster says, no way to hit 2,900 or whatever that glitched run said.
Bump up the ram to max, tackle the bus a bit(7448 will go 200mhz stable as it is designed for that) also dont forget the higher clock ram also! and the score will go higher.

Even with a faster bus etc. I don't see the score increasing by 40%. However, all that speculation won't get us anywhere. Get the hardware, do the mods, run GB and then we'll see. :) If you can reliably get 2,900 color me impressed.

Just go to my thread about OCing my DLSD, I got higher score with running 189MHz bus and 1,89GHz core on 7447. With a 7448 its worth OCing it to the rated 200MHz of the 7448 and letting the core have its 2GHz. If I ever get the files for allowing the DLSD to run with 7448 than I will also do the 7448 swap and then unleashing the 200MHz bus and 2GHz on the core(maybe higher if thermals will allow it. EDIT: Higher score than his score, I just want to say that the 7448 has more potential in it.

I don't doubt that ocing will get a higher score. I doubt that a G4 will get 2,900. You seem to think it is possible based on that obviously glitched GB run.

I dont say it will get 2900. I just say he can get more by playing with the bus. I assume somewhere between 1100-1300. I think its worth the try, the 7448 is really capable CPU.

It sure is - with realistic expectations :)
Yeah, reality is a *****. But I assume what he can manage to pull of with his 7448 by looking at the datasheet of the 7448 and then at my achievements with 7447. I just recommend the 200MHz bus and staying with 2GHz core. It can get him like 100 points or so.

Hi! Does someone in EU have a spare dualcore or quad G5 ? I wanna buy one but the ones on ebay are very very pricey and the shipping to EU is super pricey too.

I have one.. I am barely using it.. The drives have all my stuff on them, but i am willing to sell it to you if you want. I am not really using it anymore, as its in a box - new like condition. Let me know if you are interested.

I never had a problem with overclock my wholw life, also my MDD has 7457 so lower heat output and higher clock tolerance. The 7447 is running in the DLSD’s for 15 years on 1,67GHz. Than why not NOS 7457 freshly soldered on the daughterboard. It even have lower voltage and right now im not even at 1,67GHz just at 1,5GHz. I plan 1,89GHz the same as my DLSD’s 7447.

Ever get that 4GB running yet ?

I will write you, of course I am interested. And the 4gb is in dead end. It would need datasheet for Apple parts and I dont have them. The U2 and KeyLargo have some conflicts when rearanging the memory maps.
