Right now, over last 24h I got another 33 blocks.
I guess my CPU miner still loses from the ASICS and GPU miners, even when the difficulty is 1. Or I made a mistake somewhere.
That's one possibility. Did you have any 'accepted' (by Bitcoin Core) blocks? That maybe just didn't propagate quickly?
What's your hashrate like?
I think it's 6.58Mh/s:

Indeed; around 50,000 times slower than a BM1397 chip. That means you're trying 1 hash every 166.7 nanoseconds, meanwhile the ASIC can do one hash every 3.333ps. I'm honestly not sure that you need anything much faster for a difficulty of 1.
How many tries will it take to find a valid block at this difficulty? 1 or 2 tries, no?
I know from ASICs that the driver tells the chip to go through a whole range of parameters, otherwise the overhead would be too high.
In case the CPU miner is configured similarly, maybe only asking for new work every couple of seconds; that could be a problem.
I did miss the requirement of ~40GB disk space in mocaccino's guide, but it wasn't too bad; IBD went relatively quick.
I used
nullama's guide.
I may try it myself; just don't really feel like stressing my computer hardware so much.
