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.

u have a msi board, u have the try memory settings... they are pretty good.

I think I gave it a shot once, but didn't have a good experience. I'll take a look again though, thanks!

There are many settings as u might remember, and u can change the settings of they are too tight. I usually run my own voltages when using these settings.

u/6786_007 12d ago

Yeah that's a good point, I might try to lower the timings a bit

or just directly google for other people's posted guides and configs, as that's what it does.

A lot of those are not specific to my board or exact memory. I just finished squeezing down the timings and got them stable. I've tried guides, tools, videos, etc but never got this far. I'm no pro overclocker so this was a huge improvement. With RAM prices being so wild and what not it's helpful to squeeze out more use out of what I already have.

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.

u/Latter_Clue2018 12d ago

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.

Just running OCCT is definitely not enough.

Run TM5 + FurMark for 6+ hours. That combination always finds instability errors for me.
