exists. Basic research suggests that non-overclocked Ryzen supports
DDR4 2133 at most with four DIMMs (if you have single-rank DIMMs), and
DDR4 2666 if you have two single-rank DIMMs. Dual-rank DIMMs go slower,
down to 1866 MHz for four of them. Intel's Kaby Lake CPUs support DDR4
2400, apparently more or less universally. For more fun, apparently the
situation is changing frequently as AMD and motherboard vendors do stuff.
How much performance difference this makes is unclear, but various sites
say it can make a real difference (although I think they're usually
overclocking). And I have no idea how you figure out who is selling
single-rank DIMMs versus dual-rank DIMMs.</p>
<p>(This mess, like the ECC mess, is the kind of thing that tempts me to
throw up my hands and punt back to Intel.)</p>

That's really only suitable as a "I just need it to work for two days until I can get more real grease", though. The conventional wisdom in the PC enthusiast community seems to be that fancy overclocker grease (Arctic Silver is the oldest and biggest name) is only slightly better than generic white zinc-oxide packets in terms of temperatures, but much better at not drying out and causing problems like this a year or three down the line. </p>
<p>If you're using the stock CPU fan you might consider getting an aftermarket one. You can spend arbitrary amounts of money on the fanciest models, but basic tower coolers with quiet 120mm fans start at about $25 (US). Ryzen heatsink mounting is in a bit of flux right now, but since the type of people who buy fancy coolers and the type of people who buy brand-new CPUs overlap, you can find a lot of heatsinks that are compatible with both Intel and AM4 sockets, or that have a mounting kit available to make them compatible.</p>

<p>Is the 32GB RAM speed thing actually a significant performance drop?</p>
