So where is "CPC On"? - yes, next time I will try out 'Merlin's CPC On thingy'. (I heard that this is only for expensive memory, therefore I first tried the CPC Off version.)
Hi, CPC On (1T) and CPC Off (2T) is sort of a hidden memory timing, which used to be selectable in bios on older VIA chipsets (Socket A) and you can find it also on AMD64 chipsets. When set to 2T it allows to reach much higher FSB (well, at least in theory) with tighter memory timings - is especially useful while using dual channel and 1GB (or more) of total RAM memory. A serious con is, that it decreases the overall memory performance, especially in 3D applications. In stock bioses it's always On. Here's the best explanation I could find :

The CPU interface does seem to afflict system performance in my case (again, 3D applications and benchmarks) but less than with Abit NF7 I've had. On my long dead Epox 8RDA3+ rev.2.1 it also allowed me to reach higher FSB when switched to 'Optimal', but again with performance loss. The 'Optimal' setting might have allowed you to do FSB233 with 2x512MB dual channel - I personally prefer lower FSB and the 'Aggressive' setting.

Yeah the nice thing about this nForce boards is the possibility to adapt the fsb automatically. In daily life I switch with speedfan between fsb 133 and 233 (idle / load). multi 9.5, Vcore 1.47 v. 80 mm-cpu fan: 1200 rpm; 3 x 80 mm case fans, 2 @ 1050 rpm, one @ 1200 rpm. cpu-temp: 36° and almost no noise. beautiful!


@ mrapples :
Well, it depends also on the week of production and on individual CPU you have - e.g. for AMD XP-M 2500+ IQYHA 0408 was one of the best weeks (the 8th week of 2004), but there was another one I can't recall, that was simply a tragedy - 2.4GHz with voltages about 1.9v.

Your 12v line seems to be fine with 22A, providing the PSU isn't one of those Codegen (Code****) or Megabyte ones.
