AMD claims a maximum of 3200Mhz, yet my system runs at 3600Mhz
AMD claims a maximum of 3200Mhz, yet my system runs at 3600Mhz
Hello, your PC is ready for use now. The AMD Ryzen 3900x supports up to 3200Mhz DDR4, which matches the 3600Mhz RAM you have. The website mentions an optimal setup of 1600Mhz for stability, but some users attempt higher speeds like 1800Mhz for compatibility. If you don’t overclock and set the RAM to 3200Mhz in the BIOS, it should run smoothly without issues. Changing the BIOS settings won’t force the CPU to overclock automatically, so your system will behave similarly to a 3200Mhz build. Just be sure to follow the recommended values for best performance.
1-) The performance gains from using a 3600MHz RAM would be diminished if your infinity clock runs slower than ideal.
2-) Definitely true.
3-) Possibly yes.
4-) I wouldn’t purchase the 3600MHz unit, try running it at 3600Mhz with IF at 1800; otherwise, just set RAM to 3200 unless the cost difference is substantial.
Unless the price gap is large, higher speeds are preferable.
Thanks for the explanation. I prefer not to push it to 1800 since it's already unstable. Adjusting unknown settings only makes things worse. If I revert to 1600, I hope it works better. My CPU seems to fail then.
The Ryzen 3700X performed very well with a 3200 CL14 boosted to 3600 CL16 and an F-clock of 1800. I’d probably start by testing it at its default settings before lowering the clock.
They believe XMP/DOCP adjusts automatically for a 1:1 ratio. I think I'll give it a shot.
Check my profile, my two 3600CL17 chips run at 3600Mhz and 1800MHz FCLK on the motherboard with a 3900X. I also have a set of Patriot Viper Steel 3733 RAM sticks available, though I haven't used them yet. Plus, I own four XPG 3200 RAM modules, purchased when I first got my 3900X.
