RYZEN DDR4 MEMORY, WHAT YOU NEED TO KNOW!

It's a total minefield a kit that is working one day is not working the next after a bios update. Sometimes not even booting.

These rapid roll out bios make it impossible to make an accurate list and keep it upto date.

For my bundles I will keep improving performance over time with later bios and advise accordingly.
Indeed one day my system boots up from cold zero problems. Next day 3 reboots oc failed 4th reboot works whole day no problem. Next day 0d error have to cmos clear and load profile and boots bo problem.


I cant remember any platform that had souch much random problems going with ram.. Hope they fix it with few bioses :/
 
I got some Trident z C15. Running at 3200 15-15-15-35 1.35. So basically at its rated spec. Rock solid in the CH6.

16gb in x2 8gb

3600 CL16 running at 3200 CL14 no issues. I could go more with messing with bclk but not worth it with the hit and miss boot problems.

Hi Guys,

Happy to report that my G.Skill Trident Z 'F4-3200C15D-16GTZ' kit worked flawlessly at 3200Mhz out of the box :)
Just used the XMP profile on my Taichi and that was it.

I've managed to get an extra 100MHZ out of the memory with BCLK overclocking without issue. Going much above 104 and i start to see issues though.

The extra speed does give you some extra performance, so if you want to squeeze every drop go for it.

I had to increase CPU SOC voltage up from 0.0250v to 0.0750v, but this is well below maximum recommended. I've also increased PLL to 1.85v, but i think i can lower this back to 1.8v. Memory voltage is at 1.425v, but im going to test it back at 1.4.

I will certainly give it a try. Does messing with blck disable pstates?

I've only just noticed 1.5v!!! Was that just a bench run?
 
Nope. I don't use LLC so idle voltage is quite high, but load voltage drops to 1.46v.Listened to some advice from The Stilt on oc.net that he recommended not using any LLC which = LLC Auto i the bios.
I'll have to play with this to find what mine is. I could use my fluke but the points are awkward to get at whilst it's in a case. What are his reasons for leaving it on auto?
 
Got a new G.Skill kit this morning using Samsung B-die. No issues booting at 3200MHz 14-14-14-34 on the Taichi, having previously been unable to boot at anything higher than 2666MHz with the dual-rank, Hynix-based Corsair Vengeance LPX kit I had before (no matter what I tinkered with). It's actually a 3866MHz kit, since that was cheaper than any of the actual 3200MHz ones I could find bizarrely, but works perfectly well at the lower bin and timings. Hopefully it'll work above 3200MHz too if/when AMD allow anything higher than that.
