Ok with the wisdomf it's running a lot faster, around 63500s each.

Boinc, I can't remember at what point it failed, it was almost at the end.
Raspbian Wheezy.

I didn't try to overclock, because i have two power-consuming USB-Devices, so the PSU is already running at it's limit.

I have made 4 WUs each.
For my RasPi 2, BRP v1.06 and v1.42 (NEON) took almost the same CPU time.

Average:
v1.06: 90236s
v1.42 (NEON): 89239s

7.4.42 didn't compile, so I went with 7.5.0

Does "top candidates" mean you've actually seen signals, or is it where you expect them to be?

I think the BRP6-Beta is more optimizing the PCIe-bandwith than the memory bandwidth.

So, AMDs next generation gpu is said to have a successor of GDDR5, HBM, at least the high end model.
Could be interesting for E@H, as here the memory bandwidth is a major limiting factor (as far as i know).

Good to know, thank you.

As a new RasPi2+Raspbian owner, may I ask why you compile boinc by yourself instead of using the one from the distribution?

It isn't just an opinion, it's a fact.
One unpatched computer can harm the whole internet or can even bring you to jail if someone is doing bad things with it.
You really shouldn't leave an XP computer connected to the internet.

So these are my results.
Looking forward for the new cuda version.
