Which is why I asked the above questions. The same does happen on my cpu here, which is an AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ = | CPU 1 | Idle 713,8% | 1000 MHz 1182,6% | 2,00 GHz 23,9% | 1,80 GHz 9,5% And the idlestats are empty for the second core = Package | CPU 0 POLL 0,0% | POLL 0,0% 0,0 ms C1 79,6% | C1 79,5% 2,7 ms | CPU 1 | | Peter --===============5337814070477445118==--
