Falcon RGB adapter question

[marbosar77]

Hello again guys.
Very recently I have applied the clock patch V3.0 on my vanilla Falcon, as well as the fpu overclock (40mhz). I did everything explained on exxos webpages, connected and soldered everything, but... when I turn on the computer, a message shows on monitor saying "Not optimum mode resolution", even if all the lights turn on.
If I go back to "vanilla mode", everything works again.
What could it be?
Here I attach some pictures of what I have done.
As you can see, I'm using a vga-rgb adapter, and I have yet to apply the SDMA clock line delay (could that be the reason?).
Any help would be very appreciated!
Thanks in advance.

You have to setup the adapter with the software and select the resolutions to use etc. You can't just plug it in with a OSC and expect it to work. You likely have some resolution which your monitor doesn't support.

I also assume you are powering the adapter when using the OSC else you will be introducing problems with the Videl clock.

Please see the information here. viewtopic.php?f=20&t=935

Also you need a battery in your RTC else your falcon will be booting with random settings which isn't going to help. There is software to setup defaults here. viewtopic.php?f=10&t=599#p3991

Also you need to select "delay off" on the clock patch https://exxosforum.co.uk/atari/last/fal ... #V3CHANGES as you are likely causing a clock malfunction in not setting it up correctly.

I also assume you cut the track under the FPU socket before inserting the FPU OC board ?

@exxos many thanks, and apologies.

What kind of wires did you solder to the clock patch ?

Are these copper wires ?

[marbosar77]

@HigashiJun of course, copper wires with envelope. Why did you ask?

That's what I wanted to hear...

Everything's good if your wires are insulated.
