First, thanks to both of you for your quick answers.
: I could check it with a multimeter on the motherboard, it's fine. The Cpu receives its normal voltage and isn't overclocked. The adapter allows to fool the mobo for 1.70 or 1.75V; I will try it later.
The voltage regulator IC is designed for 1.65V and even less, but not necessarily all components of the voltage regulator, especially the flywheel Mos, which sees more current
. I wonder if an overcurrent protection may prevent booting although voltages are fine afterwards. I will try to underclock the Fsb to 66MHz, thus drawing less current, and see what happens.
I bought the adapter and the Fcpga
in one sale, I hope they fit together. Four other customers, with unknown mobos, are satisfied with that combination. The adapter has few jumpers : voltage and Fsb, all are at "default" up to now - that is, the informations from the Fcpga are to be transmitted to the motherboard.
The 800MHz Fcpga is a PIII Coppermine at 800MHz/100MHz/1.65V
, I hope the described modifications hold only for Celeron Tualatin. Would be nice!
Do you believe the Award 4.51pg
could provoque such symptoms? And does anyone know which Bios version is sold by www.rd-computer.de
, who only guarantee booting with 128GB drives and know nothing about processor recognition?
