I can get 3466 16-16-16-16-21-37, but 3600 18-21-37 just refuses to work

DDR4 OC stuff [tumblr_static_filename_640_v2] Firstly, should note that max safe voltage and temps for DDR4 is not being said, supposedly XMP allows 1.5V Secondly, safe X370 SoC voltage is also unclear Well, thats good start! Stage 1 Set memory voltage to 1.5V Set SoC voltage to 1.2V Its really unclear whats safe maximum, so 1.2V for now With X370 Taichi I have sticked with SoC load line calibration = LLC 5 Also, for some reason fixed works better than offset Set tCL-tRCDWR-tRCDR-tRP and tCWL to 16 Best possible end results 12=3200MHz 14=3466MHZ Set tRFC to maximum for now, 990 is my cap Set desired MHz, try 3466MHz Save and restart, if its booting, thats good enough, if not? then you go back down to lower speed, like 3200MHz Back to bios thinkering! Lower tRFC till it wont boot, start with 400, then 350, 300, 290, 280 etc Go back +1 tRFC till it boots, like 280, 281, and 283 boots, and thats ok for now if it crashes later on during tests then you just bump it by +1 Lower memory voltage till it wont boot, go back by one step Shut down PC Lower SoC voltage till it wont boot, go back by one step Shut down PC Done, you probably have successfully running 3466MHz 16-16-16-16-??-?? tRFC 280ish Stage 2 Stress Testing for sake of tRFC Fast stability tests Geekbench 4 https://www.geekbench.com/ Aggressive stability tests Warframe Destiny 2 Slow oven cooking tests Memtest http://hcidesign.com/memtest/ Crash Go back to bios and bump that tRFC up by 1 If it’s stable, then thats that, done How long is “stable”? I have managed to get Warframe crash after couple hours How stable is stable? Weeks and weeks without crashing Notes: I highly recommend to check DDR4 temps from HWiNFO64, for reference my 3466 CL16 peaks 55.8C, 24h averages 42.2C https://www.hwinfo.com/download.php Troubleshooting After completely turning off PC, memory doesnt seem to work, and it resets to defaults? Bump SoC voltage up by one …
