Help overclocking F4-4000C19D-32GTZR on asus maximux XI extreme with i9 9900k

[marcolisi]

I use my pc to play high pc demanding vr games but I also do a lot of video conversion .

Would there be a lot of difference in the pc between 3800 mhz and 4133 mhz ?

[hq-hq]

with 64gig you will stuck@ 3800MHz too and i see no benefit from 64gig ram if you are a gamer

maybe some future AAA titles will suffer on 16 gig ... 64gig if you want to use a ram drive or maybe video editing ...

[marcolisi]

Ok! Let's try! I am going to order the F4-4133C17Q-32GTZR and wait until the last moment to return the other ram.


Do you think going for 64 gb is not worthed ?

[hq-hq]

F4-4266C17Q-32GTZR 1.45V -> DDR4-4266, CL17-18-18-38

F4-4133C17Q-32GTZR 1.40V -> DDR4-4133, CL17-17-17-37

so F4-4266C17Q-32GTZR is pushed with higher voltage, so i think both are equal... i think i would take F4-4133C17Q-32GTZR

if the promised 4133MHz are working you can go higher and you can push the voltage up to 1.45V

[marcolisi]

I still can not go past 3800 MHz with the setting you just suggested :-(
Thank you so much for helping me.

According to gskill support, the rams that are in the list here https://www.gskill.com/en/configurat...471&model=3495 should work on my oc at the specified mhz.

Do you think I should get 1 of these below

F4-4266C17Q-32GTZR

F4-3733C17Q-64GTZR

or should I go for what you suggested ?

Hi,

i think it is more easy to reach higher clock rates if you use one of these three kits.
I would choose GTZR with window in the case and if not maybe GTZSW. Maybe GTZR.
These two are listed in QVL

Your dual ranked kit is tricky... best is 2x8 single ranked followed by 4x8 single ranked ...

if you give your dual rank kit a last chance test

DRAM CAS# Latency = 19
DRAM RAS# to CAS# Delay = 26
DRAM RAS# ACT Time = 46

DRAM Voltage 1.45V
please try 1.20V vccio and 1.30V vccsa


if it will not work change it for 4x8 single ranked GTZR and please report if it will run @ 4000MHz or 4133MHz@ 19 19 19 39

[marcolisi]

Do you think that at this point the best solution would be to return this ram and get one of these 3 ?

what annoys me is this all false marketing of asus and gskill about their z390 motherboards and rams with "super speed" of 4000 mhz and above , when the reality is that these new rams and new motherboards do not work at the speed advertised and the end result is that we have to still buy old ram that is meant for z370 motherboards

[marcolisi]

[marcolisi]

It did not boot at 3900 despite all the changes

[hq-hq]

yep that were the right ones

and DRAM Voltage is set to 1.40V ? (and for testing you can use 1.45V it is not a problem, but don`t go above 1.5V)

VCCIO 1.15, VCCSA 1.25, DRAM Voltage 1.4V ?

please try 1.20V vccio and 1.30V vccsa too

if there is no effect to get the 3900 then try

tCAS = DRAM CAS# Latency = 19
tRAS-CAS = DRAM RAS# to CAS# Delay = 19

[marcolisi]

Can you please check that I set these correctly ?

The pc started at 3800 mhz but not at 3900 mhz

So we went from 3600 to 3800 mhz.

Regarding the program, I installed it , but it seems it is not working for my system

[marcolisi]

Do you have an image with where I can find the above settings in the bios? I can't find them

[hq-hq]

tCAS = DRAM CAS# Latency
tRAS-CAS = DRAM RAS# to CAS# Delay

please set DRAM CAS# Latency and DRAM RAS# to CAS# Delay to 17 (if it is not working please set it to 19)

look for third timings:
tRDWR_sg set to DRAM CAS# Latency
tRDWR_dg set to DRAM CAS# Latency
tRDWR_dr set to DRAM CAS# Latency
tRDWR_dd set to DRAM CAS# Latency + 1 [ for example 17 + 1 = 18 ]

and check please:
tWRRD_sg = ~30
tWRRD_dg = ~25
tWRRD_dr = 4 to 5
tWRRD_dd = 4 to 7

if they are lower please set them to 30, 25, 5, 7

to mem tweakit

on asus homepage i see it is advertised for z390 asus rog mainboard, but i cant find download link, newest version i can find is 20170830 but it is for x299 platform :-/
http://dlcdnet.asus.com/pub/ASUS/mb/...8_20170830.zip

[marcolisi]

I can't find any of these

tCAS
tRAS-CAS

DRAM READ to WRITE Delay sg = tCAS
DRAM READ to WRITE Delay dg = tCAS
DRAM READ to WRITE Delay dr = tCAS
DRAM READ to WRITE Delay dd = tCAS +1

What is the last version of mem tweakit ?

[hq-hq]

wow, your board uses on automatic sharp timings - like

could be it is a little bit too optimistic :-D

@3600 it uses 15 15 15 36 and so on

so we can loosen them up a little bit :

please set:
tCAS 17
tRAS-CAS 17

i think automatic logic will set the others based on them also a little bit higher *hope so*

- if it will not work you can try tCAS 19 and tRAS-CAS 19 too

and somewhere deeper in the bios settings must be secondary and tertiary timings

this style:
DRAM READ to WRITE Delay sg = tCAS
DRAM READ to WRITE Delay dg = tCAS
DRAM READ to WRITE Delay dr = tCAS
DRAM READ to WRITE Delay dd = tCAS +1



--- Mem TweakIt

ok, it should work with z390 but maybe they locked it for "ROG"- i don´t know
