Setting up G.Skill F4-3200C14D-16GTZRX

[dusank]

Hello,

I've just purchased F4-3200C14D-16GTZRX.

I've got information that these modules provide AMD Ryzen optimized Samsung B-die chips - Is that correct?

I want to run the memory at least at its specified parameters: 3200MHz, 14-14-14-34-1T, 1,35V.

I've got an ASUS Crosshair VI Extreme board with a Ryzen 1800X processor.

I've tried to use AI overclock tuner in the BIOS and select D.O.C.P. Standard and I've also tried to manualy input memory settings (14-14-14-34-1T, 3200MHz, 1,35V).

My computer either boots up with JEDEC #6 values at 1066MHz memory clock or freezes and reboots within few minutes after booting up Windows 10 Pro.

This also happens at lower frequencies (3066, 2933).

Is my RAM defective?

I was using Corsair CMU16GX4M2C3200C16R successfully at 3066MHz but returned it to try G.Skill memory that claims to work at 3200MHz with Ryzen. But for me it is not even working at 2933MHz ...

---------------------------------------------------------------------------------------------------------------------------

I have returned the memory kit as it was IMHO faulty. Received a new one today and although not perfect it behaves much more reasonably.

I was able to set AI Overclock Tuner to D.O.C.P. Standard (3200MHz, 1,35V, 14-14-14-34).

AIDA64 Business Cache and Memory Benchmark passed without any problems.

But when I ran System Stability Test I've got a "Hardware failure detected! Test Stopped." message after few minutes and few minutes later the system froze and rebooted.


So I've tried to set the timings manualy leaving D.O.C.P. at default.

14-14-14-34-2T, 1,35V, 3200MHz: Unfortunately the board does not boot with 3200MHz for some reason - after boot JEDEC #6 values are effective as shown with CPU-Z

14-14-14-34-2T, 1,35V, 3066MHz: Cache and Memory Benchmark passed without any problems. I've run System Stability Test for almost 10 minutes but then I've got a "Hardware failure detected!. Test Stopped." message .Few minutes later the system froze and rebooted.

14-14-14-34-2T, 1,35V, 2933MHz: Cache and Memory Benchmark passed without any problems. I've run System Stability Test for 19 minutes without any issues.

I've performed more tests a bit later:

14-14-14-34-2T, 1,35V, 2933MHz: Tried to reproduce the 19 minute System Stability Test run several times but unfortunately the system either freezes and reboots or I get a "Hardware failure detected! Test stopped." message few minutes after the start.

14-14-14-34-2T, 1,35V, 2800MHz: Cache and Memory Benchmark passed without any problems. I've run System Stability Test for 2 hours and 3 minutes without any issues but then I got a "Hardware failure detected! Test stopped." message.

Can you please give me advice on how to configure the system for better stability and performance?

I bought the most expensive and powerful AM4 components (motherboard, CPU, memory kit) so I hope there is a way to run them at 3200MHz which they all AFAIK specify to support.

Thanks.

I can confirm that the CPU IMC was indeed the culprit.

I have RMAed the CPU yesterday and today got a new one. The motherboard boots up with 3200MHz DOCP without any problems and AIDA64 System Stability Test is running for 40minutes already without any issues.

I would like to suggest that you add G.Skill F4-3200C14D-16GTZRX to your ASUS Crosshair VI Extreme QVL as I can confirm that it works with the motherboard flawlessly. (ASUS Support insisted it is not on the QVL due to the RX suffix)

This is my first G.Skill memory (I've been buying Corsair before) and I am very satisfied with it and the motherboard!

Thanks.

Have you left all values the same or did you change anything after choosing DOCP.

Same.

Ok I chose stilts safe 3200 and chose 4ghz OC profile and im stable with aida64 for 7 hours. Also changed cpu voltage from auto to v1.4 and I believe SOC to v1.17

Well, I don't know if the G.Skill F4-3200C14D-16GTZRX would be considered the 'best' memory...after all, the G.Skill F4-3200C14D-32GTZ is currently running at 3200Mhz, and is made up of 16GB sticks, not 8GB sticks (more on the way...). Stable with the latest BIOS (not the beta), so far as I can tell, no special settings, save setting the speed...

Still, I have had the odd reboot, which may be linked to that memory...or the fact that the room temperature is closer to 75F+ & the AI Suite recently failed me (thanks MS)...or it could be the aging RX480, soon to be replaced with a Vega Frontier Edition (wanted a Vega 64, no one had it in stock for a reasonable price...I'll take the card with the twice the memory and a FPS or two slower + CAD precision in the case). Don't know. That and Corsair (whose software just won't stay up)...

I was not aware that there is a 32GB kit that runs at 3200MHz.

Yet what is 'best' really depends on ones needs. For me 16GB is more than enough, thus the better price, the RGB lights and the Ryzen optimization are all making this kit better for my own needs. I could argue that for most people 16GB is more than enough IMHO.

[BlackBishop]

But 32GB kit is made of two dual rank sticks and is limited to 3200, 3333 max speed. So hard to call it "best" 😉

And when Asus supports faster RAM with 16GB modules, I will be there.

Until then, 64GB@3200Mhz feels so good it hurts (rofl).
