Hello,

I have a Ryzen 1800x, Crosshair VI Hero and G.SKILL 32GB 3200MHz Trident Z CL14 Ram. My issue is that I can't set the ram frequency to 3200 Mhz, system reset there is short beep and bios reset ram to 2133 Mhz. I have latest 1501 bios. Max ram speed that I can set is 2933 Mhz. Cpu is not overclocked, every setting is on auto except ram voltage is 1.35V and ram frequency is 2933 Mhz.

Here are my timings and cinbench score:

Is it possible for me to run these sticks at 3200 Mhz??? Will I have a noticable performance gain if I manage to set it to 3200 Mhz?

Hi,

https://rog.asus.com/forum/showthread.php?95000-Need-Help-G-Skill-Trident-Z-F4-3200C14D-32GTZR/page2
Stable options are your default choise.
XMP for Module Name G Skill TridentZ RGB F4-3200C14-16GTZR
@ 1600 MHz 14-14-14-34 (CL-RCD-RP-RAS) / 48-560-416-256-8-6-39 (RC-RFC1-RFC2-RFC4-RRDL-RRDS-FAW)

Change voltage of ram to 1.35 than 1.4 if not stable/working.

Thanks, I have configured bios like in the post you linked and it's worked. I don't know however why I need to increase the cpu vcore voltage I have left it on auto and it's working too.

And of course thanks for the video.

Here is the updated cinbench score.

I helped muffinman1604 set up the same memory. He got away with tweaking the tfaw to base setting, and the trfc down to 350. It will reduce your latency by a fair chunk.
try

TFAW 24
trfc 350
trfc2 260
trfc4 160

This should be stable, but obviously check it with a stability checker. HCI memtest seems to be the most preferred atm. Or memtest 86 if you can be bothered to make a USB boot drive.

Voltages he had set up were.

CPU to offset and +0.03125v
SOC to offset and +0.0500v

Both with LLC level 1

Dram at auto 1.35v

I have configured the bios settings exacrly like in this thread tfaw 24 trfc 350 trfc2 240 trfc 3 160 but I have left cpu voltage on auto becouse I don't understand why is it nessecary to increase when im not overclocking cpu. Also the proc_odt I have set at 96 ohm. Everything is working this configuration passed 2 hour prime95 blend I will do a memtest and other tests later. Thanks.

Regarding vcore voltage.

As I understood it from that forum thread, it done on 1403 bios and 1501 bios voltage is behaving differently.
In my case, it is all over the place.

Regarding way how it is done, offset mode is needed if you want to save power when not needed.
This is best I have found regarding offset mater: http://www.overclock.net/t/1628504/ryzen-7-overclocking-guide

You may not be OCing the CPU, but you are OCing the memory. As such you need to confirm that the system is stable in all areas. The recommended voltage for a 1800x is 1.42v very top end. This is the sort of voltages people are using for a 4.0 OC.

Most are running around 1.34v for a 3.8 OC. So running at base speed you can probably get away with 1.34v no problem. Having lower voltages will help keep your system cooler, as well as reduce on electromigration. Which will make your system last longer.

If you have left it on auto, then you are probably overvolting beyond 1.4v unnecessarily.

But in this thread he is increasing vcore. I will overclock this cpu to 3.9 or 4 ghz propably.

In case of vcore voltage on auto I can see that it is spiking to insane 1.7v with all
cores excluding one on 3,6/7Ghz and one core on 4.0/1Ghz.

When you enable offset mode vcore voltage is fixated on 1.35v according to “Ryzen Master”

It means 1.35v + 0.03125v = 1,38125v (not engraved in stone when LLC in auto)
If your LLC is on auto under load/stress test it will go down 1.333v~ to stabilize this
behavior you need to change LLC (Load-Line Calibration) from auto to some fixated value
“LLC level 1 or 2”as suggested by Pawemol12.

Internet is overlay saying 1.35v max for long lifetime.
That gentlemen from AMD is saying 1.425v max to have long lifetime of silicon.
This is still unclear for me in context of electron migration.
Any motivated input would be nice.

I have read somewhere that overclocking is worse for gaming becouse it disables precision boost. Do you think it's worth overclocking?
