[SOLVED] Can't get Corsair LPX running stable at 3200Mhz with Ryzen 5

[caiofernandesart]

Motherboard: MSI Bazooka B450M
CPU: AMD Ryzen 5 2600x (Water Cooled)
RAM: 32GB (2x16GB) Corsair Vengeance LPX DDR4 3200Mhz (CMK32GX4M2D3200C16)
GPU: ASUS GeForce GTX 1050 Ti
Storage:
250GB Samsung SSD 970 EVO Plus
500GB Samsung SSD 860 EVO
Power Supply: EVGA 650 N1, 650W

I had a Trident Z RGB kit that was giving me a lot of headaches related to instability since ever. So, I decided to buy those Corsair Vengeance LPX kits because it is compatible with almost every motherboard and also it is a pretty popular average kit.

It does resolved my instability issue, indeed. However, I can't get it running stable over 2933Mhz, even though it is rated at 3200Mhz.
At 2933Mhz it's rock solid, it doesn't crash at all. On the other hand, at 3200Mhz it can post but it will eventually crash over load. XMP profile doesn't resolved neither Ryzen DRAM Calculator timings suggestions.

Any clue what might be? Anybody experienced something similar?

Very common not to run at the full 3200. 2933 is often the sweet spot on Ryzen setups.

Ryzen is finicky.

Have you tried adjusting DRAM and SoC voltage to try for 3200mhz?

You'll probably need to tweak some of the very many timings parameters to get it stable.

I'd suggest to go look for the Ryzen Dram Calculator utility. If you know exactly what DRAM chips your DIMM's have it will help customize the timings for your CPU and memory. You will have to plug all the values in to BIOS. No guarantees because so much relies on specific silicon quality of the IMC in the CPU, but it beats the heck out of the long hours you'd spend randomly changing all those parameters.

HWUnboxed put together a great how-to using it on a Zen2 chip, but Zen1.5 should work pretty much the same. Just don't get giggity over the high memory clocks he's using as Zen2's IMC is vastly improved.

Yeah, guys. I did all of those things;

I guess my specific Memory Chip + Motherboard combo it doesn't pair well at 3200Mhz.

Thank you all for your time!

Maybe the sticks are overheating? You have watercooling is there any air going over the memory sticks? I have corsair 2400mhz memory running stable for weeks@2933mhz with 16 17 17 36 54 timings, that's dissapointing if you can't get the 3200mhz ram to run any faster.

Doubtfull that sticks are overheating when they are running below rated xmp speeds.

Yes it's probably something on the zen+ cpu incapable of higher than 2933mhz, like the infinity fabric. I guess when you eventually upgrade cpu the ram should have no problem running 3200mhz+.
