| As for previous discussions about PowerMac module adapter,
I'm trolling ebay for dirt-cheap PowerMac parts to kill and probe out. Made a Megarray PCB footprint as a start. I bought a few Megarray connectors some years ago, not sure where I put them though, but they aren't horribly expensive. Who has a broken AmigaOne module/motherboard for probing to figure out the connector pinout on our end? I'd rather not kill my XE board... _If_ we get anywhere, who's brave enough to test such a thing? :)

| Finally, I installed a 7455A@1266 in my AOne.
First information, I found why I can't set my CPU at 1266... Above 1133, Uboot show a wrong frequency, but the real CPU speed is correct.
I wanted to overclock the CPU, but with the 4 dips switchs, the multiplier jumps from 1266 to 1533. Of course at 1533 the machine crashs in a few minutes. So I finally tracked the 5e PLL, and removed it, to get intermediate frequencys. My 1266 Mhz 7455A is actually clocked at 1466 and run stable with a slightly raised vcore (and of course a correct cooling). Trying to make it crash.
I haven't done too much benchmarks, but SysSpeed give me 2140 MIPS and 810 MFLOPS, Quake 2 timedemo runs 31.5 fps in 1280*960 with 9000 pro. Quake 3 and SuperTuxKart are still unplayables
But at least, it works. _________________ AmigaOne XE --- 7455A@1400 --- Radeon 9000 Pro --- RAM 2GB --- SSD 40GB |

I have a heat gun here. Will this let me do some CPU hacking? |

Really ionterestingyour new G4
Any bench to post? like Blender, lame or ffmpeg comparision ?
For the TuxKart problem I think that i can work REALLY faster we can have a new 3D environment that a faster CPU... _________________ Simone"Tuxedo"Monsignori, Perugia, ITALY. |
