Can't run ram at 6000mhz, trying to figure out if it's the motherboard

It's even (rarely) unstable with bios set to default. I get blue screen or weird behavior in Windows/games.
I can run ram at higher mhz but it's very unstable. I was even able to oc a bit.

If I restart the PC the boot gets stuck at ram (default or oc). Not sure why but I tried waiting 10 minutes and nothing. I have to completely cut the power by unplugging the cable for 30 seconds and then start the PC.
Latest Bios version.

Specs:
7950x3d
Asus Rog Strix X670E-I Gaming Wifi
Corsair Dominator Titanium 6000mhz CL30 (EXPO)
Corsair SF1000L (1000w)
The temps are fine.
 
I had to use EXPO Tweaked on mine to get it to work. G.Skill RAM though. EXPO I & II both caused corruption.
 
Asus board, check VDDP. They like to give it the beans for no reason and kill stability. AMD default is 0.800V and with 6000MT/s you should not have more than 0.950V.

Corsair memory is notorious for needing a bit more juice to be stable. Check your voltages (all) with HW info and post a screenshot.

I have also had to RMA Corsair memory twice now, and will never buy it again, regardless of the specs, etc.

What brands have a good reputation for working with AMD motherboards? (I have to confess that I've turned into an AMD CPU loyalist.)

one of the others on the qvl. im using patriot...
 
I got some guidance now, thanks a bunch. At work but will test it as soon as I find some time/remember to do it. Should be later today. Will report back :)
 
I had a heck of a time running my ddr5-6000 until I figured out expo was turning off termination, setting it to Auto made everything happy.
 
So I tried some settings and EXPO I sucks bad (both default 1.4v and 1.425v, and for some reason 1.435v is the max I can set).
EXPO II was better, but I had insane slowdowns during system startup while apps are loading. I don't have a ton of apps that load on Windows startup so I don't know what's going on.
I tried Buildzoid easy Xynix ddr5 settings and they work a bit better than EXPO II, but the slowdowns are there. I literally can't use my pc for a few minutes but after that it works fine.

It seems these slow downs are caused by temp sensor readings or something connected to that?
They happen while apps like HWInfo is loading (first time I start it I get slowdown and then the app doesn't start, but the second time it starts) and during Windows tray apps loading, one of the apps has to do with sensors (the AIO screen app).
 
I had it running 6000MHZ for a bit using some settings I saw on a YouTube comment. After I updated the BIOS it became unstable. I did some benchmarks and there was BARELY a performance difference.
 
I only have 2 slots for memory modules, it's a ITX-E motherboard. Very tiny.
Buildzoid settings work mostly fine, but sometimes while starting a game I get the massive slowdown. And I have to test more the and see if it actually wants to restart like a normal computer instead of getting stuck on ram.
Maybe I need to up my voltage a bit.

I can't think of any realistic RAM speed that would cause a "massive" slowdown, to be honest. That sounds more like storage, or a software / OS / malware issue.

It seems to happen when there's something going on with USB connections or motherboard sensors. I don't think it's malware.
It does not happen if BIOS settings are set to Auto.

The slowdown is so bad even the mouse is moving in slow motion, and often it just freezes for a minute or so.
Happens always when starting up Windows, lasts for a few minutes then goes away (does not happen when waking up from sleep, only restart). Sometimes when starting apps. Always when starting HWInfo (for the first time, after that it works).
 
USB usually runs from the PCI or PCIe base clock (but not always depending on what its connected to on the mobo), so it would appear that the built-in hubs & connected devices aren't liking the speed increase. Other possibility is that the increased RAM clock is causing corruption for the USB devices.

Have you ran something like memtest86+ from UEFI boot?
 
Ths is the most frustrating thing I've encountered and it probably is AMD, I never in my 25 years had issues with ram not running at its rated speed.
I get blue screens randomly once or twice per day. EXPO I or II blue screens, timings found on the net, blue screens. The only thing that works is setting everything to auto. I'll just stick to Intel from now on.

You have a defective part in your PC. Fix it before you do anything else, simple as that.
 
I have experience with recent (newer) platforms from both AMD and Intel. Both have their issues with stability. Standard JEDEC speeds are no problem but XMP and EXPO are crapshoots with both platforms. The last time that I had a platform that was stable was back in the Kaby Lake era - but then, I did not have an LGA 1151 CPU that was unlocked (or overclockable), and the RAM that I was using with Skylake/Kaby Lake used very much JEDEC specs even in its XMP setting. I skipped Coffee Lake, Comet Lake and Rocket Lake completely on the Intel side and used only Ryzen 3000 and 5000 CPUs until Alder Lake came along. And my Ryzen 3000-series CPUs were a bit picky as far as XMP DDR4 RAM is concerned (I did not have access to AMD-rated DDR4 RAM at the time I built those PCs).

As a user of a PC strictly for workstation purposes, I learned how to manually set the RAM speed, timings and voltage to the maximum JEDEC spec that the CPUs support on my current 14th-Gen Intel and AMD Ryzen 7000-series platforms although the XMP and EXPO settings that I used with both were no problem (stability-wise). Then again, I did not want to significantly shorten the usable life of either one of my current CPUs.

And setting the RAM to the default settings will almost always run the memory speeds that are slower than the maximum JEDEC-supported speed of current-gen CPUs: These XMP/EXPO DDR5 RAM kits have a maximum JEDEC profile of only 4800 MT/s (don't call these ratings MHz, for crying out loud!) while the official maximum for 14th-Gen Intel and 7000-series Ryzen are 5600 MT/s and 5200 MT/s, respectively. (9000-series Ryzen officially supports 5600 MT/s for DDR5.)

Our 7900x3d rig uses 6,000 mt/s instead of the 6400 expo. 6200 mt/s worked good too but 6,000 is quieter and a bit tighter.

I have tried to avoid EXPO, but at this point I just might make my nephew very happy and give him a 7950x3d/64gb/4080 gaming station.

It's your PC, you need to figure it out. You can open new thread, people will help you out. Once you do, RMA defective parts or buy new ones.

My comment is a reaction to your statement that you will be buying Intel from now on - you should know that Intel CPUs and Intel-based motherboards can have the same failure rate like AMD, so it is not a solution. The solution for your problem is to troubleshoot your PC - accurately, and replace what's defective.
 
Adding, the difference performance wise is extremely minimal. Arguably, even with huge memory performance jumps (which this is not one of those).

YMMV of course, but too many "other things" are usually the bigger bottlenecks to address. I guess in theory if you're "running the best" everywhere, maybe, but 6000mhz? Doesn't really sound "the best" at that point, you know?

However, if someone can offer a "night vs. day" comparison of 5600 (shoot even 5200) to 6000.... I'd be interested.

You are correct with "most" saying that 6000 should be possible in most all cases though.

It is possible that one of your sticks of RAM is defective if you have some stability issues even at the fail-safe default memory speed of 4800 MT/s. I recommend that you troubleshoot the RAM, one stick at a time, by running something like Memtest86+ or another memory testing program that’s recommended by the [H] users after removing one of the sticks of RAM, and then swapping out the one stick that’s in your system for the first run with the other stick and then running the test again. If one of those sticks has a far greater number of errors than the other, then it’s RMA time for the memory kit.
 
I would suspect memory first. If its having issues with different memory sticks from different manufacturers, then I would suspect the board.

I normally build with Kingston and Crucial. I haven't had issues with corsair with machines I had repaired.
 
I used crucial RAM for my new build
https://www.amazon.com/gp/aw/d/B0CTHXMYL8

Worked first time with my 8400F/Gigabyte A620I AX. EXPO I/II both worked, but I set it to EXPO II for the loose timings and lower voltage. If you have more than 32GB it might be more difficult to attain 6000MTs, it'll depend on your processor's IMC.

This makes me think either driver issue, or unstable USB bus (which could be caused by memory, or it could be caused by the CPU itself). You could try disabling any automatic overclocking/boost settings and see if it still happens. If it stops, then either you need better CPU cooling or you have a defective CPU.

If there are auto overclock settings for CPU and Memory, only disable one at a time and test after each change. If you disable both at once, then you can't know if it was CPU or Memory that was the problem

If it's anything like my motherboard, the auto OC setting was enabled by default. Thanks Gigabyte.
 
I did not OC the CPU and it's hovering around okay temp, below 80 when gaming and 85 in Cinebench.
I did Memtest and it passed each stick and then both of them. Except once something happened when it was running overnight and I woke up to a black screen, but a second run with the same stick passed fine.
But I keep getting random restarts when the PC is idle. Blue screen and it restarts, and that's when it often gets stuck on ram so I have tu completely cut the power for it to start up again.
 
Try another power supply. But it sounds like faulty motherboard.
PBO, voltages are all default? No overclock and no underclock? Everything on default?

Everything except ram, which is at 1.4v

I tried that and I think I got even more bluescreens.

I will admit that the motherboard I bought was a returned ex. But I figured it was because of the very loud fan it has built in, which was fixed with a bios update.
