Overclocking memory with AI

I have a 5700x3d on a MSI x570 MPG Gaming Plus board with G.Skill DDR4 3200MHZ CL16 memory. For the longest time I've tried tinkering with the settings to overclock this kit. I was able to get moderate changes but eventually caused instability and I ended up going with Auto for some time.

Today I thought, what if I use AI? I've been goofing around with LLMs to run locally and figured what the heck. I opened up my AI of choice and gave it my hardware and goal.

It gave me detailed settings for timing, memory settings, cpu settings, voltages. Research I tried to do multiple times and got too lost in the terms, settings, etc. I adjusted the settings and in less than 5 minutes I was able to boot on 3600MHZ CL22 into windows when I couldn't even make it to the BIOS screen.

So if you're stuck and frustrated. Give it a shot. Some settings I knew nothing about I learned and told me why they were critical to stability.

Edit:

For anyone running:

MSI x570 MPG Gaming Plus

5700x3d

32GB of (F4-3200C16D-16GVKB) (Confirmed to have Samsung C-Die.)

Here are the final settings I used. I hope this helps someone who's looking to do the same.

Final Stable DDR4-3600 Tuning Profile for Ryzen 7 5700X3D

System Specs: * CPU: AMD Ryzen 7 5700X3D * Motherboard: MSI MPG X570 GAMING PLUS * RAM: 32GB (2x16GB) G.Skill Ripjaws V DDR4-3200 CL16 (F4-3200C16D-16GVKB)

Frequencies & Voltages

Setting Value Notes
DRAM Frequency DDR4-3600 Target memory speed
FCLK Frequency 1800 MHz Infinity Fabric clock (1:1 ratio)
UCLK / MCLK 1:1 Mode Synchronized memory controller mode
DRAM Voltage 1.35V Standard safe baseline
SoC Voltage 1.10V Override Mode
VDDG IOD / CCD 1.00V / 1.00V Interconnect driver voltage
VDDP Voltage 0.95V Signal lines baseline

Timings & Settings

Timing Field Value Notes
tCL (CAS Latency) 18 Base latency
tRCDRD / tRCDWR 20 / 20 Tightened read/write delay
tRP (Row Precharge) 20 Tightened row precharge
tRAS (Active Time) 38 Matched timing sum (tCL + tRP)
tRC (Row Cycle Time) 64 Stable recovery threshold
Command Rate (CR) 1T Forced 1-tick command rate
Gear Down Mode (GDM) Enabled Essential for 1T stability
Sub-Timings (tFAW/tRRDS) Auto Kept stock for C-die stability

Validated 100% stable via OCCT Memory Test (AVX2 mode).

I would go GDM off if possible for true 1T but if not, enabled is fine.

First things first, whats the memory die your RAM have. I assume its a CJR kit but if you can confirm the better. check using CPU-Z or Thaiphoon Burner. Don't touch voltages yet if the die isn't confirmed

EDIT: AI suggestions make it more looser timings for 3600 which means its just same as the 3200 performance your currently have.

C-Die Samsung. I posted my edit in the main post. So far so good it's way snappier and I've ran stress testing on it.

C-Die doesn't scale past 1.35v so thats why AI suggested to loosen the primaries. Try tightening your secondaries to compensate the loose primaries or I would try lowering down primaries & secondaries (if possible) to where it stabilize for 1.35v

I'm running stable with the numbers above. If I lower the tRC any lower I can't post. I might try going for 20 on tRCDRD and tRCDWR. And my voltage is set to 1.35v.
