1) Whats the maximum recommended voltages for 24-7 usage on water (NB, mosfet and SB and CPU on water) for:

CPU PLL
Northbridge Voltage
DRAM (4x1GB D9GTRs Cellshock 1800) with active cooling (2.0V) ?
FSB Termination
Southbridge
SB 1.5V

for 24-7 ... not suicide benches

2) Is it possible to run 1T with 4x1GB sticks? Is so how? NB volts up and DRAM volts up ?

Thanks. Would appreciate any help
