Question Experiences with the "Memory Try It!" feature on the MSI B550 Tomahawk ?

Hi all,

I recently built a new system with Ryzen 5 5600X, MSI MAG B550 Tomahawk, 2 x 16 GB Corsair Vengeance LPX 3600 MHz CL18 & MSI Radeon RX 6800 Gaming X Trio.
Putting it all together was somewhat of an ordeal and when it finally booted I casually enabled XMP in the UEFI settings. After that the machine didn't post, the DRAM error led was lit and I had to remove the ridiculously huge GPU along with its anti-sag bracket to access the CMOS reset jumper.

Now, I've been looking into this and it seems that either the default BIOS version had some bugs in the XMP settings or I had bad luck in the silicon lottery and the memory controller on my 5600X can't handle 3600 MHz. I have received suggestions to turn on XMP and then manually lower the memory clock to 3200 MHz and FCLK to 1600 MHz while retaining the XMP timing settings. It seems like a safe bet but I've been hesitant to try anything yet.

I'm NOT looking to squeeze out every last bit of performance and I know next to nothing about RAM overclocking aside from what I've read during the last couple of days. I'd rather have stable RAM with a moderate performance increase than spend days tweaking timings.
Currently the RAM clock is at 2666 MHz (plug'n'play). According to various software tools the memory ICs are Micron Rev. B series.
And yes, the sticks are installed correctly into slots A2 and B2 as instructed in the mobo manual. :)
I'm also fully aware that there is no foolrpoof way to get everything working on the first try but I'm trying to gather information to avoid any unnecessary hassle since my free time is limited.

In the motherboard manual there is a mention of a feature called "Memory Try It!" It's some sort of automatic memory overclock checker that should be able to revert to previous working settings in case the RAM config fails. Can anyone tell me if it's worth trying and does it actually work? Not having to clear the CMOS after every failure would save me a lot of time. I've upgraded the BIOS to the newest version 7C91vA8

Yes it does. Version 7C91vA8. But I haven't tweaked anything after updating it so all the previous mishaps happened with the factory-loaded older bios version.

Don't know about the last part, but you can use it to test a speed step lower with say same timings for XMP settings.

You did read this?

does the ram btw have two XMP profiles and did you try both?

Yes. And that is why I was looking for experiences with the feature. In the UEFI menus Memory Try It! is right above the Memory Retry Fail settings which leads me to believe that the mobo should be able to recover from bad RAM settings (unless they are really messed up) either with, without or regardless of Memory Try It! being enabled. But it didn't happen at least with the old, factory-loaded bios. I can't remember the exact version but I think the build date was way back in 2020.

It does but they are identical. Same clock speed and same timings.

Usually when ram is at a point that ram settings are too off to make things boot or be stable does the bios revert to spd settings aka 2133mhz so is most of the times little harm in testing different ram settings. And there is also clear cmos if things are really bad.

Sure about that,? Usually timings are different.

I'm sure. After first asking for advice from the retailer (a very reputable PC part retail & custom building company) they also asked me to check profile 2. CPU-Z and Thaiphoon Burner both show only one profile though.

Since I bought the CPU second-hand, I contacted the seller and asked him if he had similar problems. He also had Corsair Vengenace RAM (different model though), a kit of 2 x 16, and had no problems with XMP profile of 3600 MHz CL18. So that pretty much rules out the CPU and memory controller, unless something happened while installing the CPU into my board.

I'm now trying to schedule myself some time to test the RAM extensively, including one stick at a time.

Not all Vengeance ram is the same so that his kit worked doesn't mean yours should too.

You could add some voltage to the SOC , maybe that wil help to stabilize. Don't go over 1.2V, just one tick above what it is now, or 0.05V.

I went with XMP profile 2 but manually dropped the DRAM clock to 3200 MHz and FCLK to 1600 MHz and kept the XMP profile timings and DRAM voltage of 1,350V. So far so good. I might try 3600 MHz when I feel like it but for now I'm satisfied unless I start running into stability issue.
