I keep puting small notes here...
It hase proved to be problems with warm restart. Lock at desktop (icons
/start menue doesn't load).
From cold it seem to start good at all voltages, now started at 1,50V and
temp keeps below 38grC.
To improve warm restart I pulled down multiplier from 24 => 22. (still at
fsb 100). There seem to be some incompatibility with RAM (256+128) that
holds the max fsb down.
(In most SOHO work it's the HDD that produce process time anyway. Running
benchmarks it's obvious that HDD, M-board , fsb and RAM put limits and that
the cpu seldom get it's power out. Gaming is a different quest where cpu
probably is more directly essential.
Basicly the differens between a 2+GHz and a 3+GHz is likely of no matter
at all for SOHO-users. I run some technical stock analysis scan-calculations
(100 stocks) and at 2200Mhz hdd writes constantly)
The real issue seems to be that there is a permanent slight instability
(althoug KT7 was perhaps the best in it's early days). I had problems also
running the duron 700 on this board. It locked during start 50%.
