Title: Sam440ep_setup 1.3 Released
Post by: SysAdmin on February 07, 2012, 06:03:35 AM

News from m3x via amigaworld.net


Sam440ep_setup is a little utility to optimize performance on your Sam440ep board (mini-itx and flex versions)

What's new:

use a more aggressive instruction cache speculative prefetching setting.
This allows a faster execution for some software, for example the following
Blender speed test increased performance by 10%-20%:

bldyn -b projects/bricks_and_water_plugin.blend -o ram:pool -F JPEG -f 0

As a sidenote some values returned by Ragemem are incorrect (MIPS) or lower
(L2 cache read64/write64) when this setting is enabled.
To disable this setting, add NOCCR argument to the command line.

Currently on OS4Depot upload queue.

i wouldnt rely only on the very same benchmark that it was anounced with. i hope it isnt only blender that takes minor advantage here, would check other applications for balanced opinion if i was a sam owner.

Minor advantage? Over 12% speed up is a bit more than minor IMHO.

I thought so too, considering that Max has managed to find the time to write this utility for a 4 years old machine... still well done! :)

I'd say yes. But I am happier knowing that ACube (Max) keep supporting their products with tweaks and optimisations, good job.

I have this feeling that Max knows his stuff... :)

Ask Max.

But I could ask the same question to Gigabyte...why did it take so long to release a BIOS update for my motherboard? Why does Microsoft take so long to patch security holes up?
Surely they are MASSIVE companies compared to one man hammering away in Italy... ;-)
