Just a quick word about my experience with the msi b450i board and 3600. I put in many hours trying different settings, so hopefully this thread may help someone else. A big thankyou to computer alliance, who flashed the board before sending it so the 3600 worked on the older board. Problems I had were cpu heat at idle 50 degree and 95 load, and the system would not boot 30% of the time. HEAT: On another thread here a user mentioned very hot ie 95 degree temps on their 3600 with the standard cooler, a few others, myself included also had the same issue. After trying many things over weeks what worked for me was: 1/ Turn off precision boost overdrive 2/ In overclocking set 4.1 to all 6 cores. 3/ Set max cpu voltage to 1.25v 4/ In windows power settings dont use the Ryzen settings. I use the "high performance" standard settings. I did also buy and new cooler -a $39 Jonsbo low profile. This reduced the load temps from 95 to 85 degrees. I'm not sure if I'd recommend that cooler tho as the included RGB fan looks pretty but is useless AF- I replaced it with a old coolmaster case fan and the temp. Its ok if you need a low profile cooler and have a spare quality fan. With the above settings temps are now 42 (prev 50+) at idle and 70(prev 95)on load when benchtesting. Gaming is about 65.Benchmarks are 1-2 seconds faster also. So cpu cooler dropped 10 degrees, and news settings dropped about 15 degrees - 25 total. The other problem, not booting 30% of the time. Hit the power button, power light would go on, fan would spin but nothing else.Cycle PSU and then it would boot up normally. I was suspecting a problem board but ended up being a ddr4 issue. Tried xpm profiles and extra dimm voltage with no luck. Solved with using MSI bios "memory try it" - the highest my mem can use is 2800 c14. Any fastest freq brings back the no-boot issue. This is with corsair lxp 32gb(16x2) c16 kit. I'm disappointed that I cant run it at 3200 but the timings help the benchmarks to be close. No more boot problems since this. hope this helps someone. cheers edit: June 2020 The new(12-6-2020) b450i bios seems to have fixed the ram issue - been running a few days without a issue at 3200 speed ram. The update is 6 months late but so far so good.
