The original 10uF values work perfectly in thousands mainboards, so there is no reason to install larger ones. The fault must be have other reasons. The Powergood line from the powersupply is important for example...

Try it ...

... both are the same except for the reset connection.

... what is a Molex PSU? You mean a pico psu with an external 12V power supply? 80 watts is the smallest and there are ATX adapter cables to build a connection cable to the Atari mainboard.

BEST has new ones to sell ...

The inductance and the 470uF capacitor feed the 5V voltage for the dram banks from the mainboard. So the memory only draws too many amps.

See the 1040ST Schematics ...

Yes.

He should build a ATI MACH32 Emulator or a ET4000W32i ...?

ET4000W32i can do 2MB of Videoram.

... only the old webside, shop is closed. There is a Nova W32i driver but 1MB only because with an 80Mhz RamDAC more than 1MB doesn't make sense.

The NVDIVGA.INF must be individually adapted for each graphics card and each adapter. The Version from me is for a VOFA Mega ST Bus Adapter and for a specific ET4000 ISA graphics card. If you use another ET4000 card you have to revise the INF. This can be done via the NVDI VMG program. Use the Googl...

You can try NVDI5 install with the ET4000 Option. NVDI 5.03 has the lasted VMG for the ET4000 and ET4000/W32 ... You have to set the NVDIVGA.INF (AUTO FOLDER) right and working with help from the VMG first. NVDIVGA.zip Nova ET4000 and W32i only for 1MB cards, Ask Idek for help or use the Nova ATI MA...
