Useless OC RAM

[Jan Hofer]

Hi y'all

I have a serious problem with my memory. Recently I bought the gskill trident z 4266 CAS 19 16GB kit for my Ryzen System. I currently own the Fatal1ty X370 itx Mobo and whenever i try to run these DIMMS at below or above 2133MHz it just won't apply and boot loops. Interestingly enough Dual Channel Mode has also not engaged. Have also not found an option to change that so far. 

 

TL;DR: How can I get my RAM to work properly in my system?

 

HELP

Did you update the BIOS to the latest one?

[Jan Hofer]

Yes I just updated the bios before starting to overclock.

Looks like the AsRock site says 2933 would work with that kit. It's really down to the IMC though.

 

Here's all AsRock seems to have provided as far as speed/kits goes.

 

Could also just make life easier and buy a kit that actually works with your platform.

Well duh ... Its on this list but doesnt work what now?

I haven’t seen a single Ryzen build with RAM higher than 3600MHz

Where does it say on the list that DDR4 4266MHz G.Skill RAM has been tested to work on that motherboard?

 

Also keep in mind, 4266 MHz is an "aggressive" frequency -- not many motherboards, or CPUs (the Integrated Memory Controller, to be exact) will be able to handle that speed. This isn't just on AMD CPUs, Intel CPUs as well.

 

At this point, either start at the JEDEC standard, DDR4 2133 MHz with 15-15-15-36-50 timings and 1.2V, and slowly work your way up (e.g. manual DRAM overclocking) ...or get a *officially* supported kit.

 

The "sweet spot" is generally in the range of DDR4 3000 MHz.

IMO, I'd recommend getting DDR4 3000/3200 MHz with CAS 14 timings, and 1.2V or 1.35V....rather than 4266 MHz with CAS 19, and 1.4V.

It specifically says on the Asrock Page that my kit is supported read carefully. I am not trying to run it at 4266 on this platform but i may want to be able to in the future thats why i did not buy a lower clocked kit. The max from AsRock supported frequency for this kit is 2933 but i cant even get it to boot with 2400mhz. Everything but default doesnt work presently.

Can you guys please read carefully. I am not planning to run with max speeds.

Ah, sorry.

I had assumed you were trying to run it at the full 4266 MHz XMP speed.

 

Whats timings and voltage did you try with 2400 MHz??

 

They indicate 2933 MHz is working, but don't mention the timings and the voltage.

It looks like you may need to reach out to AsRock, and see what values they tried, or would recommend.

 

Just out of curiosity, have you tried manually setting it to 2933 MHz, but keeping the 19-19-19-39 (2T) 1.4V settings?

If memory serves, Ryzen only uses even-numbered latency (e.g. 19 becomes either 18 or 20).

 

• Make sure you are on the latest 3.40 BIOS (dated Nov 28 2017)
• Manually set the DRAM to 2933 MHz with 20-20-20-40 2T timings, with 1.4V, and slowly work your way down with reducing the timings and voltage

I basically left latency untouched for 2400 as well as 1.4 V. My Bios is already up to date. But i am also basically unfamiliar with most of the settings though. I only changed voltage and frequency. However windows reports its running at 2133 15-15-15-38 1.35 V..

I already reached out to AsRock waiting for their answer. I also intrestingly enough heard in the recent Ask GN that they were abke to run 4500 Mhz on Ryzen. I wonder how they managed that...
