Can't get Vengeance LPX DDR4-3000 past 2133MHz on STRIX B350-F motherboard

Havardox · Aug 10, 2017

So I recently built a Ryzen system and I can't seem to get my RAM past 2133MHz despite it being on the QVL (https://dlsvr04.asus.com/pub/ASUS/mb/SocketAM4/STRIX_B350-F_GAMING/ROG_STRIX_B350-F_GAMING_SummitCPUDDR4_DRAM_QVL20170520.pdf)

I've tried the DOCP profile (2933MHz 15-17-17-35 1.35v) but it just changes back to the default 2133MHz once I reboot. The RAM kit can't seem to handle anything past 1.3v. Manually entering the timings listed on the stick, changing the frequency to 2933MHz, setting SoC to 1.1v also doesn't seem do anything.

The problem still occurs after updating to latest drivers and BIOS (0806).

System specs:

OS: Windows 10 64-bit Home Edition
MOBO: ASUS STRIX B350-F
RAM: Vengeance LPX 16GB (2 x 8GB) DDR4-3000 (cmk16gx4m2b3000c15)
PSU: Corsair CX600
CPU: Ryzen 1600
GPU: Nitro r9 380 4GB

Can I even fix this or should I just refund my current memory kit?

Your RAM is'nt the main problem.. Try updating BIOS..

check page 3-3 of use manual to see what settings ram have then on page 3-10 under my favorites wwhat setteings for ram but you might have to update bios to latest a;sp these module are the 16w or 16 r .

BIOS is already updated

this may or may not still apply after the more recent AGESA UEFI updates, but since I have no confirmation one way or the other for your motherboard that MAY be the issue (needing more than two sticks)

Some info here:
https://rog.asus.com/forum/showthread.php?94642-ROG-STRIX-B350-F-GAMING-issues/page6

He appears to get 2800MHz on the same motherboard and UEFI/BIOS version:
"I asked support the following; "im trying to get my ryzen 5 1600 and CMK16GX4M2B3200C16 v5.39 memory to run at 3200 mhz, but i am hitting a limit at 2800. is there a beta bios, or some other clues to get those speeds"

So it sounds like POSSIBLY 2800MHz is doable with some tweaking. Not sure if the CPU must also be also overclocked to get there? (very confused.. ).

Either way, I think we need more UEFI/BIOS updates for memory stability.

UPDATE: RAM is stable at 2666 15-1-7-17-35 1.35v. Interestingly, anything above 2666 would instantly cause instability, even at 1.5v, 1.1v SoC. Buggy memory support is most likely the issue here.

these kits on this link have samsung b-die on so they will reach 3200 check the latency they use with yours .
