discussion Ryzen 7000 - 4 memory sticks

[sswilson]

AMD for 20+ years and never actually had issues populating all 4 memory slots on any system unless a stick is actually bad then the failures are no-posts and things like that... nothing like what your describing.

What your describing really comes more off as a more general windows/drivers/software issue. iCue crashing isn't uncommon, corsair commander 1gen software was an absolute hot mess for something so expensive etc.

Yeah, I'm thinking video card / drivers as well....

Have you tried the undervolt setting on your vid card? What's your current vid card settings in the adrenalin app? (There's a setting for pushing your vid card memory, maybe disable that?).

i do understand this, but what i am also looking for is ways to test wether or not the system is stable.
doesn't really matter how the timings/clock/voltage is set or what they are set to, if the system is not stable.

hey KBA, you're missing the point I think. the timings, clock speed, voltage are what need to be adjusted to make the RAM stable. JEDEC has issued standards for faster DDR5 RAM now, but originally it was 4800mhz @ 1.1v with 40-40-40-46. I couldn't find anything exact for anything faster, but taking that JEDEC standard, it means you need to play with timings and voltage in order to get faster speeds that remain stable. running memtest will show if the current settings are stable or not.

so, for a starting point, set your RAM at 4800mhz, with loose timings like 40-40-40-50 and voltage at 1.1v and memtest. if stable, raise the speed to 5000mhz and memtest. continue this until memtest fails. at that point step the voltage up by a notch and memtest. raise the voltage by a notch until memtest doesn't stable and then raise teh clock speed. eventually you'll get to the point where you have to loosen the timings, perhaps change the CPU : RAM divider.

of course, to make sure you will have the best chance of success, make sure you have the latest motherboard BIOS installed and the latest microcode issued by AMD for their 7000 series CPU.

- of course, other parts of your build can cause instability, like the two posts above this that comment on perhaps the GPU being the culprit.

I just recently got a brand new card back, so I am still seeing if it makes any issues.
While looking into all these issues I just happen to find out about the ram situation, therefor I was looking for way to stability test my system specifically on the memory part, since I already know of ways to test other stuff

For ram I only knew of memtest and wanted to make sure if that was enough

hey KBA, what I would do is set your RAM to a lower speed and make sure your memtest passes. once you have that proven, if your system still has problems, you can rule out the memory as being the cause.

memtest is enough. if you have a single error, it means something is wrong with the memory. so if you have an error, you need to start doing tests to eliminate possibilities. the first step is ensuring your BIOS and microcode is up to date. if you still have errors, pull out all but one stick and test. and then test all sticks one at a time with memtest. if they all pass, you start doing combinations of two. if those all pass, you add a third stick and so on.

Agree with what everyone else is saying. Two points:

1. Doesn’t sound like a ram problem, but if you want to 100% confirm, just pull 2 sticks (1st and 3rd). Run the pc and see if the same thing happens. If it does swap the 2 remaining sticks with the ones you pull, and check again. If occurs during those scenarios, you know they are not the problem.

2. As others said, it seems most likely to be a windows/software/driver issue (not a GPU/RAM hardware) problem.
