Also you can try training options
go to AMD-->CBS-->DDR Options-->DDR Training Options and set:

(Training time 4:10 minutes)
RX2D_TrainOpt = manual
TX2D_TrainOpt = manual
TX DFE Taps = 3 taps
RX2D voltage step size (2^n) = 1
TX2D voltage step size (2^n) = 1
RX DFE Taps = 3 taps
or
(Training time 4:50 minutes)
TX DFE Taps = 4 taps
RX2D voltage step size (2^n) = 1
TX2D voltage step size (2^n) = 1
RX DFE Taps = 4 taps
or
Auto (longest memory training from 9-12 minutes)
RX2D_TrainOpt = auto
TX2D_TrainOpt = auto
TX DFE Taps = auto
RX DFE Taps = auto

The training time is given for 128 GB. For 192 GB it will be longer
What will be better specifically for you needs to be tested]]> Sat, 19 Oct 2024 21:17:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=157146&title=x670e-taichi-192gb-ram-with-9950x#157146 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=157071&title=x670e-taichi-192gb-ram-with-9950x#157071 Author: DemonAk

time to test these settings:
reset all settings and set in bios:

dram freq: 5200, 5400, 5600, 5800*, 6000*

dram timings: all auto
DFE Read Training = Enabled
Gear Down Mode = Enabled

Once stability is found, you can turn these back to Enabled:
Memory Context Restore = Disabled
Power Down Mode = Disabled

voltages:

VDDIO = VDD = VDDQ = 1.36
VSOC = 1.22 or 1.25
VDDP = auto
VDDG CCD/IOD = auto
VDD Misc = auto

Infinity Fabric = 2000
UCLK = MEMCLK

bus configuration:

ProcOdt = 48
ProcCaDs = 30
ProcDqDs = 34.3
DramDQDs = 34

RTT_NOM_RD = 4
RTT_NOM_WR = 4
RTT_WR = 2
RTT_PARK = 5
DQS_RTT_PARK = 5

go to AMD-->CBS-->DDR Options-->DDR Training Options and set:

RX2D_TrainOpt = manual
TX2D_TrainOpt = manual
TX DFE Taps = 2 taps
RX2D voltage step size (2^n) = 1
TX2D voltage step size (2^n) = 1
RX DFE Taps = 3 taps

Memory training time will be 3:40 minutes each reboot until you enable these settings
Memory Context Restore = Enabled
Power Down Mode = Enabled]]> Sat, 19 Oct 2024 04:28:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=157071&title=x670e-taichi-192gb-ram-with-9950x#157071 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=152877&title=x670e-taichi-192gb-ram-with-9950x#152877 Author: NDRE28

Hello!

I have the same motherboard & CPU as you do.
I went with 2x32GB DDR5-6000 CL30 RAM kit.
However, I had to lower the DRAM frequency to 5800MT/s, as with 6000MT/s I had some errors in MemTest86.

When running 4x48GB DIMMs, it's a lot of stress that you put on the memory controller. The official supported speed in that case is 3600MT/s.
You won't be able to go much higher than that!

So, it's a trade between density & speed.
You can't have both!

I'd suggest using only 2 DIMMs, which will be faster & better in most situation.]]> Mon, 30 Sep 2024 04:55:41 +0000 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=152877&title=x670e-taichi-192gb-ram-with-9950x#152877 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=152630&title=x670e-taichi-192gb-ram-with-9950x#152630 Author: naeq

Changing values of ProcOdt doesn't work either. Maybe something is broken on the bios side? This is the first bios on which it is possible to attach 4 sticks of ram on ryzen 9000 series, maybe in the next update they will change something for the better.

Try ProcOdt 60 or 120 if you not POST with 48 om]]> Thu, 26 Sep 2024 20:25:29 +0000 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=151720&title=x670e-taichi-192gb-ram-with-9950x#151720 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=150945&title=x670e-taichi-192gb-ram-with-9950x#150945 Author: naeq

Thanks DemonAk, I have tested the settings you wrote in every possible configuration, but unfortunately nothing works for me. I can achieve 4200Mhz with impedance + gear down, but anything higher doesn't boot.]]> Tue, 24 Sep 2024 20:38:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=150945&title=x670e-taichi-192gb-ram-with-9950x#150945 https://forum.asrock.com/forum_posts.asp?TID=66407&PID=150602&title=x670e-taichi-192gb-ram-with-9950x#150602 Author: DemonAk

Hello,
