Re: REV 3 - The beginning
It looks like something really starts to struggle over 61Mhz. I have disabled the SDRAM as well.. I think it could just be the bus isolators.. I mean they take 20ns to disable... along with the ROM it is mostly moaning the ROM is having problems being accessed, and I have slowed its access right down as well. I put the plastic package one in which otherwise is working fine at 50 MHz, that one does not even boot up, so I assume it is the CPU actually tripping up and nothing else.
I am going to put a faster buffer on the next revision of the board. It is hard to find one that JLC stock , which are actually faster as well.

Re: REV 3 - The beginning
Yeah i never got 030s past 56-57Mhz without parts of them stopping to work. Think there is a fundamental limit somewhere there.

Re: REV 3 - The beginning
In terms of long-term stability 50Mhz seems to be about as high as you could really go anyway. I have ordered a couple of supposed different mask EC's to see if they are any different.terriblefire wrote: ↑Thu Apr 08, 2021 1:01 pm Yeah i never got 030s past 56-57Mhz without parts of them stopping to work.

Re: REV 3 - The beginning
Been busy rerouting the buffer isolator chips... It went from two chips to one chip, the fastest one I can really find is a ABT version. About 7ns isolation time, the old ones were about 20ns.

Re: REV 3 - The beginning
The board was running most of yesterday at 50MHz on my H4...
The results I was keeping a eye on.. The GEM dialog box ( actually that should probably be spelt dialogue ? ) It was interesting because in the morning the test was 300%.. And during the day when it all heated up in my room picked actually dropped to 299%.. And around midnight when it had dropped in temperature it went back up to 300% again! just goes to show how very small tolerances in hardware can affect things.
