So I finally got round to replacing my ageing Opteron 146 CABNE 0545 with a brand new Opteron 146 CACJE O604 as the CABNE got stuck at 2.75. Booted this one up to 2.75 first time and then onto 3Ghz with only 1.45V. Havent got screenies yet but have run 3 hours prime and superpi 32m as ive only had it since this morning Will prime overnight and hopefully push this chip to 3.1 maybe 3.2 with a bit more voltage. Screenies to come.
