Raptor Lake doesn’t support CUDIMM. They will work without CKD. But they will waste your money and they have absolutely terrible timings. Go Aida for fun… 9400 is slower than my 8000…

Okay. Doesn’t look as bad as I expected. Have you run any proper memory tests? TM5, Karhu or y-cruncher?
no
i plug and play
i never mess with ram oc before and read not much minimal improvement
8200 is really overclocking. With those tests you would see that they are definitely not stable. With memories that are not stable you will only break your headphones and your hearing. If you are not interested in tests and tuning, you should stay at 6000Mt/s. XMP is always overclocking.
i shall trial tomorrow as my friend is streaming plex
It’s the hardest of all. Start TM5 1usmus.cfg it will give you hints where the problem might be. Also download HWiNFO to see your memory temperatures, over 45c usually produces errors and it is reached in tests really easily.
Here is a link to unlock TM5 error codes
edit. you can skip the whole y-cruncher completely. And be satisfied and confident that there will be no really strong spikes if you get TM5 and Karhu through. Then remember not to use the machine during the test and turn off the screen shutdown in the power management for the duration of the test.
TM5 with 1usmus. Remember 25 cycles about 2.5hrs
What motherboard do you have?
Without XMP it sticks to some really slow settings below the manufacturer specified memory speed, like my DDR5-6400 CL32 would stay at 5600 or similar. With XMP Profile 1 it goes to the specified 6400 CL32. And can run memtest86 for 48 hours without errors, which is my base test before I use any hardware for anything…
Yeah, usually 6000/6200 works with XMP without problems. But it’s not guaranteed. And for 8000+ speeds you always need a 2-slot motherboard. I’m just trying to warn everyone that it’s really easy to break speakers or headphones if the memory isn’t completely stable. Even more likely to do that is dsd1024 and browsing the internet at the same time. Really just a matter of time.
Mine is two slots anyway, since it is mini-ITX ASRock Z790 PG-ITX/TB4
I would be more worried about critical data being corrupted (disk write caches, etc). Another good test I have is to build HQPlayer OS. It loads all cores at pretty much constant 100% for about 12 hours, plus of course heavy I/O. I’m using two top speed M.2 disks, 2 and 4 TB. 64 GB of DDR5-6400 CL32 RAM.
Now with latest Intel microcode performance and stability are both very good.
For me, machines must be 100% stable under any load that one can possibly generate.
P.S. The machine is running Ubuntu Desktop 24.04 LTS.
P.P.S. My normal HQPlayer OS / NAA OS build machine is Xeon with 64 GB of ECC RAM.
haloe
i have asrock z790i lightning
how to get longer tm5 test?
1usmus.cfg completes in 10 min. passed but how to make longer?
It seems to be the best option to work easily from what I have read on overlock.net. Congratulations! It can even work all autol Or just by adjusting a few settings but I can help until the end if there are errors.
Did you press “Select config” and 1usmus.cfg? It should be automatically 25cycles.
When the test is finished, post a picture of it so I can see any errors.
PS. Do not press OK when the test is finished because that will also close the test!
It doesn’t apply to mITX motherboards, but that’s a good motherboard. I had the same one on another machine before and it ran exactly 7000Mt/s. The AsRock Z790i Lightning has to be the best option for music lovers at the moment. I haven’t tested it myself, but I’ve read a lot of good things online about how easy it is. My Apex is really difficult if you haven’t adjusted it before. And on top of that, the hardware breaking down, 8000 speeds when tightened are a completely different thing than 6400 XMP. I’ve had it crash several times and even broken one of the tweeters and was so scared that I really don’t want to experience that again!
It may be that a couple of degrees above 40c cuts everything off and you can imagine how it sounds through the amplifier. I mean by this my own experience with tightened 8000 speeds and I really want to make sure that the memories work in all situations for sure… That’s why I make sure that even in stress tests the memory temperatures don’t rise above 40c, because then I know that they will definitely stay below 40c during normal use. DDR4 could still withstand the heat, but DDR5 couldn’t.
And unstable memories cause WHEA errors in Windows which eventually mess up the entire PC.
The first one was apparently wrong.
Here you can find the correct one and the new one
If you get a lot of errors for even 30 minutes, take a picture of that phase and stop the test. That way, you can probably fix it by changing the voltage. Of course, it’s possible that it will pass cleanly the first time!
@Eminent_One Did you get the test done?
halo
yes per dm
i am stable with downclock to 8000mt for 1.5hrs time at end of config cycles
good enough for now
