exxos's DFB1 trials

[exxos]

I looked around the internet and slim pickings for PSU images. There was the odd one with the same resistor missing but that's about it.

I got the same as badwolf in my c-lab mkII.

What does your 5v measure as ?

[DoG]

5.05V

[exxos]

5.05V

So basically everybody's power supply in the whole the world measures correctly other than mine then :lol: :roll:

One in 1 million all right... 1 being the chances of me actually getting something which functions correctly :lol: :roll:

[exxos]

So if you want something to work properly then fix it yourself then really..This power supply WILL bend to my will :twisted: :twisted:

I have been upgraded to the super swift service :D

5.05V

... mine is the same as the one from DoG with R18 missing and with DFB1 and Nova Falcon plus ATI MACH32 VRAM card it has a voltage of exactly 5.00V. Q1 on the Powersupply has 60 Degree after 30 minutes operation what is fine ...

That is way too close to the edge, Frank :)

On my Falcon I have R18 + a recapped PSU and I read 5.00V.

On 3 DFBs with the release firmware I have the FPU working in one, sometimes, sometimes fails on a few ops in fputest. On the other two so far the FPU isn't working (bombs in fputest). I've not yet beeped them out or tried any mods.

Have you tried a slower oscillator say 40MHz ?
