@ Wolf2000me :
I'm not sure, if I'm asking too much
If Merlin's gonna make something really special for us, not only fix some minor issues (the cold boot issue and S3 state power saving), some tests are necessary. It would be good, if you could make similar tests like mavers from hslab.pl once did : let's say FSB200 with the most aggressive timings (but stable) and multipliers 8, 8.5, 9, 9.5 and so on with the 12.5x multi at the end. At this FSB your CPU is able to handle all of them and we'll see, how well this bios is optimized and if there's antyhing that could be eventually fixed.
The tests : Sandra 2005 memory tests and Everest Home (1.51 is the latest one) read and write tests (plus delay time). I would do this myself, if I were in Poland now - shouldn't take you more than a few hours, plz.
@ mrapples : 2 x CD-rom drive and some fans makes something like 10-15 Watts - it ain't much. What's your system like - could you list everyting?
