absolutely on your own there.

Triple fried chip ram speed, nice!
I keep thinking of your dungeon and Young Frankenstein. Make sure you don't upload the CPLD file titled 'Abby Normal' :lol:

Have you managed to look at the IDE TF issue when overclocking?

Also with your new coding, how are the thermals. CPLDs still 'balls to the wall' and warming the dungeon in this cold weather or are they more relaxed and sipping a Pina colada on the silicon beach?

The CPLDs are even hotter.. They're moving more data...
I've not got write burst working yet.

I've also seen some a1k.org people (including Jens) whine that i'm leaving performance on the table by not caching ROM. My thought process on this is twofold..

1. ROM is already stupid fast.
2. Most people use an MMU CPU and have MUFastRom running.
3. Based on 1 its a waste of cache. Cache the things that are slow.

Hence i dont mark ROM as cacheable. I think we get better results this way.

Performance is looking incredible there =O I would't bother with dedicate ROM caching when MMU gives good enough performance there. It's looking super fast from those benchmarks!

Figures look great!

Great numbers!
Though, the earlier versions than SysInfo 4.4 will show some greater numbers for the chip mem speed, so perhaps it would be good to run 4.4.

Better 4.5b12 because it shows instead of chip speed vs A600, straight CHIP FAST and ROM speed in megabytes per second

Bustest is how I measure memory speed. Can’t be bothered upgrading my 20 images to new versions.

wow those numbers are looking really nice! What a great piece of art :cheer:
