DDR5 ram’s stability
i bought this expensive kit 2x16 ddr5 rams . i have expo turned on and i set it on 5800mhz max is 6000 mhz . i just wonder how can i make sure that i have stable experience with this ? im gaming + recording games and it is smooth never had any errors or stuff like that but if i get 1 second lag or something im freaking out and thinking is it cuz of the ram is not stable ? im pretty rookie to it any help would be appreciated!

Why not just run the stock 6000 heck who not just run the stock settings at 6200 when you are testing anyway

hardware is not idiot proof anymore, if you dont undervolt your cpu, either intel or amd, or the 16 pin connector, if you dont know how to properly pressured mount the socket or properly apply thermal paste, your hardware is gonna blow up, no matter what. Right now you have a killer vsoc voltage applied to your cpu because of EXPO. Your cpu is degrading by the minute. If you want to leave the amateur stage, come to my discord, i'll teach you how.

i have ryzen 77800x3d and i changed my vsoc on 1.200v

Don't let this guy scare you into buying whatever scam course he's peddling. Your CPU isn't going to blow up even at 1.3V. You'd have to try hard to mess up thermal paste application and if you do, you'll see it in the temps for example in HWiNFO. What are your timings? Something like 32-38-38 or 36-36-36? What does the serial number on the sticker say at the end? Based on that you can determine what die type you have and what settings are likely to work. Assuming it's hynix a- or m-die, you could start here, these settings are way faster than the defaults and should work on the vast majority of kits (of that die type).
For testing I like to use TestMem5 with the included 1usmus config (you can select the config under settings) for quick 30 min initial test and at least a few hours to letting it run overnight with the ryzen3d config. 1.2V sounds reasonable for 6000 MT/s, but make sure it's stable (1usmus will throw errors if it isn't). For 1usmus there are error tables that hint at what the problem could be. You should also run y-cruncher's VT3 test to confirm memory controller stability. The runs should be successful and the results not too different run to run. Let me know if you need any more info.

thank you so much for this reply and your time. timings are 36-36-36-96 . and i am running 5800 mhz instead of full 6000 . i did test (from the windows when it restarts and doing 2 tests and i get 0 errors ) do u think this is enought ? i mean i don't have any issues or something i think im just overthinking and this guy comes and says weird things makes me even more overthinker ! thank you anyways <3

36-36-36-96 is Samsung die so the video above doesn't really apply. The way you want to test usually is increasing MHz as high as possible, confirm it's stable, increase infinity fabric clock as high as possible(confirm stable) and then timings. It always depends on how far you want to push RAM OC, because it's very time intensive. I'd recommend finding a good baseline (like a rock solid stable 6000MHz with 2000 IF which gets you 90% of the way there anyway especially with an x3d cpu) and then testing small changes from there.
Which tests did you run and for how long? Ram instability can manifest in subtle but annoying ways (like small stutters or audio hitches), so to me personally, I find it important to have a configuration that I can reasonably trust to be stable. There's different opinions on how long to test exactly but imo a couple of hours ryzen3d config tm5 and stable y-cruncher vt3 should already be pretty hard to pass for something even slightly unstable.

and do u think should i mess with my cpu underwolt settings aswell or im good at default with this settings enabled ?

Don't mess with cpu undervolting (Curve Optimizer/Curve Offset) while stabilizing ram because both can produce very similar errors. Unless you mean vsoc, which is definitely part of the ram stabilization process, and should be adjusted if the ram configuration demands it (e.g. errors 0 and 6 in 1usmus and more vdd doesn't help)

not enough, with the spikes you most probably will have you are dangerously close to 1.3 v, the maximum allowed for AMD who had to released an urgent update on the release because at more than 1.3 volts the imc explodes.

Homey... are you trying to act like you're a pro, shilling some personal "discord access" and talking about 1.2 vsoc being dangerously high? That shows that you either don't know what you're talking about, or are being intentionally deceitful.
u/Alive_Message_7865 - Regarding VSOC, it doesn't need to be 1.2v when your memory speed is so low and can probably go lower, but there is no danger to it being 1.2v either. The only downside is that it will eat into your power budget a tiny bit, but the performance hit from that is extremely small and limited to heavy multi-threaded work, not gaming. If you are super new to overclocking, do not worry about this at all, 1.2v is fine.

The maximum allowed safe vsoc voltage without LN2 is 1.30v for a reason. Above that, it can damage your cpu. Maybe dont use the highest LLC level for your vsoc/imc and nothing bad will happen at 1.3v. The voltage spikes are causes by high LLC setting. After AM5s release, they reduced the allowed vsoc voltage to 1.3v because that is the highest harmless option.

RAM instability will typically show up as crashes, not lag spikes.
If anything, lag spikes can happen more often when your RAM is slow.
If you want to ensure your memory is stable, run a memory test for some hours. I recommend TM5.
