Road to 3466+ ram on X470

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I've been stuck on 3333 @ cl14 for sometime. I did ran 3466 as a quick test on the 1.52 beta which i couldn't boot on the previous bios but rolled back to 3333 as i was busy at work. While the initial test was stable in test it tends to randomly closes my game while streaming. 
either way hope i could get feed backs or suggestions to reach 3466+ which seems to be rare on x470. The ram kits i'm using have been tested on an intel system to run xmp @ 4000 but we all know the amd system is more sensitive to timings and higher ram speeds.

currently running 14-14-14-14-30-44 @1.65v anything

i'll start to run RDC on 3466+ but i'm confident it doesn't run/boot at those settings so i'm open to suggestions

	i must say 1.65 volts on yours ? seems a bit high ,there was a lot of discussion saying that the extra heat from over 1.5 volts was self defeating and making the ram more unstable

	yeah i have many problems doing 3466@cl14 yes from coldboot, resets to 2166, slow loading apps and app crashes plus the fact that we can't load bios profiles is the main reason i stopped at 3333 that was a typo its on 1.35 but i do push it to 1.65 when i feel like playing around with the ram btw does disabling geardown effect anything because up to now i haven't touch that setting

	geardown ? hell yes when set on your ram will show 1t (its being forced by bios to use 1.5t) it also prevents odd numbered cl timing eg no cl15 and will bump it up to next even number,in the case of my old ram that was cl15 it would boot into windows set at cl16 your ram im sure is single sided single rank so it should be set to geardown = off bank group = off bank group alt =on my cold boot literally only comes for no known reason after 2 weeks stable ........... i cant advise enough to try using the ryzen dram calculator as it delves into the more hidden settings that it seems the am4 platform needs to configure the ram in bios or even search out the stilts advised settings (he now writes ram profiles for asus bios to ship with)

	played around with cl 14 / 15 / 16 at 3400 it boots but closes app on heavy load stream+gaming these are RDC settings at different speeds tested with 1.35, 1.40(rdc) and 1.50v seems the system likes cl 14 than the higher ones for some reason cl 15 & 16 doesn't boot perfect but retains the settings

	Download Ryzen DRAM Calculator and thaipoon burner (alternatively you can just click on "Read XMP" in RDC) You'll be up and running at 3466MHz+ in no time.

	RDC safe settings doesn't fly @ 3466 v1/v2 i'm already thinking of using 3333 strap 3:50 and pushing to 104 to get 3466 Edited by gizmic - 11 Sep 2018 at 6:56pm

	You need to select the right settings for your memory. Eg are the chips used Samsung B/D/E/S-Die, or Hynix/Micron etc. You can't just select V1/2 then hit "R XMP" and "Calculate Safe" and expect the settings to work you have to select the right parameters in the calculator to get usable results.

	Most CPUs have a memory "hole" where its unable to train memory from 3350-3450 MHz up to 3500-3600. This means you might be unable to run 3400 MHz DRAM frequency but 3600 is OK. Edited by kerberos_20 - 12 Sep 2018 at 5:00am
