Thanks I'm still on the fence about this, but I might go for a lower rated Crucial Ballistix kit with E die then instead of the lottery of whatever chips are in the LPX 3600C18. Prices are comparable, so I won't be saving much, but at least a little bit. And of course ~3400c14/15 sounds a lot better than 3600c18. I'm guessing the Corsair needs decent quality dice given its relatively high clocks, but c18 isn't particularly impressive, even if it is at 1.35V. I suppose Pushing the LPX to 1.5V might allow for tighter timings, though. I might buy both and return whichever is the worst performer, if I have the time to properly tune these.

The chipset itself doesn't matter for memory speed/compatibility, but the board does, and X570 boards are (supposed to be) engineered with better trace quality than previous boards - logical, as DRAM has been the one field where Intel has soundly beaten AMD up until this point. Another new thing is the decoupling of IF speed and DRAM clocks in Zen2, which I don't think carries over to the Ryzen 3000 APUs (which are Zen+). Then again even Zen+ IF links should be capable of handling 1700MHz (3400/2) speeds, and I'm not going bargain-basement for my B450 board either.

I like the Ryzen Memory Calculator in theory, but in my limited experimentation on my Biostar X370 GTN with my TridentZ 3200c16 it didn't help at all. I can run XMP timings if I set the speed to 2933 (3200 crashes intermittently), but the timings from the calculator wouldn't POST at all, sadly. Then again this motherboard is ... not good. Looking forward to replacing it with an X570 board in due time
