Question DDR5 CL30 6000mhz XMP unstable?

[haloguy1999]

So I've built a new RTX 4090 PC just in the last couple weeks, using a 7800x3D, MSI MAG X670E AM5 board, and a kit of G-SKILL ripjaws S5, CL30 6000mhz, 32gb - and I think I am having some stability issues related to the RAM.

I've never really had a crash during gaming, that wasn't obviously related to a GPU overclock, however I've had my PC lockup, cut to black, and restart when using chrome, or just general web-browsing. I notice somewhat regular flickers/stutters when watching youtube or streaming as well.

These symptoms get heavily exacerbated when I modify the memory training settings (to get faster POST times), like the 'powerdown enable' and the other setting - it crashes more often.

I don't really know anything about memory overclocking outside of the absolute basics, I'm usually an 'XMP and leave it' type of person - and I've never really had issues like this before on such a high end machine. Is there a defect somewhere here, or is it just poor luck and these parts are unstable at these speeds (even though everything is mostly stock outside of a GPU undervolt)? Is it even a RAM issue?

Would greatly appreciate any advice here to hopefully figure out what is going on!

Does the RAM have EXPO profiles?

Is the ram on the motherboards QVL? AMD is very picky on what ram it likes to use.

Not sure how reliable this site is, but no, I don't see my specific memory on this list for the MAG X670E

Does the RAM have EXPO profiles?

No, not that I'm aware of, it's just stock or XMP, I don't think it's EXPO

I started with G.Skill Ripjaws S5 RAM, had all sorts of issues because it's XMP and not EXPO profile. Sold it and bought G.Skill Flare X5 EXPO and all my issues were gone. The lesson being, Ryzen 7000 was built for EXPO, using XMP with it is a gamble.

Yikes, didn't know that. I have until February to return this RAM so that's fine I suppose - is there any particular models you guys would recommend for EXPO? I guess I could just pick one off the QVL list, as well.

Thanks for the link, I couldn't find an official page lol - also yeah, mine is not there.


** EDIT **

Found these sticks - would these be fine, assuming I'm running stock speeds? https://www.newegg.ca/g-skill-32gb/p/N82E16820374419

That's the RAM I replaced my Ripjaws S5 with and it solved my issues.

I should point out my motherboard said it could run with the Ripjaws S5, and it did on the 1st BIOS version (F1), then they released newer BIOS versions to help voltage control to stop the X3D chips from melting the socket and new memory controllers etc. After I did a BIOS update, all my RAM issues started, and the old BIOS was nowhere to be found on the website.

Awesome - I'll pick these up and return the other ones, hopefully that fixes things. Thanks for the assistance everyone!
