Question PRIME Z690-P not working with all 4 RAM sticks

[berbes]

Hello! a client has a PRIME Z690-P with 4 Vengeance 16GB chips. No boot. i removed the RAM down to one stick, got it to boot. Updated BIOS (it was oooold), got it to boot with 3 sticks, but no boot on all 4. stuck in a completely different Kingston Fury Beat 8GB RAM stick in the 4th slot and it boots. I've swapped the sticks around...sometimes the BIOS see them, other times, not.

I'm thinking this has to be a click or two in the BIOS...I just have NO idea what those clicks are. These are the screenshots.

THANK YOU!!!!!

A "client"? So you're a professional, but you don't know how to troubleshoot memory problems? And you are unfamiliar with advanced configuration of memory settings in the BIOS? How do you have clients if you don't understand these very basic concepts?

Are you sure this isn't your system?

so, you attack instead of inform? there are a few really great folks here that have helped me in the past, and then there's you.

good luck with that bowel movement, son. it's all about the fiber.

If you think that was an attack, you must have only discovered the internet yesterday. That was no attack. Those are legitimate concerns.

How are you supposed to help somebody that is supposed to be a professional and has "clients" if they have no understanding about any of this? Besides which, if they ARE a professional, we are not here to DO THEIR JOB FOR THEM. This site is to help PEOPLE, not businesses. If any person comes here, or to me, asking specific questions about how to do something or about how to troubleshoot an issue, I'm always more than happy to help them. Ask anybody. It's why I've been one of the most active members of this site for the last ten years as a moderator and then a retired moderator, and many years before that as a visitor. But I don't come here to provide assistance to somebody who is making money off something they are supposed to know how to do.

Hence my leading question to see if it was actually the OP's system and they were just trying to seem, IDK, more important, by having "clients" so we could dispense with that and get down to trying to solve the issue if they were willing to admit it wasn't for a client but for themselves. I don't know who you think you are to presume to judge anybody here, but I assure you, this island ejects malfeasants rather quickly so I'd advise you to stow your personal attacks, which is all your post is as it in no way offers any help to anybody and only exists to be excremental.

It's funny how people who only come here once every two years think they have some right to jump in anywhere they like and start slinging insults at people who are here every day for ten years, because they FEEL like it slights somebody, having no idea whatsoever why we ask what we ask, say what we say or do what we do. I'd suggest either you offer to provide whatever valuable information, if you have any, that helps the OP, or refrain from becoming involved in matters that you are only complicating with no ability to assist with.

4 sticks and ddr5 do not work well together, without slowing them way down. Often, below JDEC's 4800 base speed. If they want 64gb ram, they should do a 2x32gb kit.

thank you, sir. this was an issue where everything worked for them until it didn't. i was hoping for a click somewhere in the BIOS to make it work again, but i appreciate the knowledge

I have heard that bios updates breaking such things before, ironically on Asus boards.

you having a bad day? i was only responding to a post calling me a liar.

i come here when i need a fresh perspective. after dealing with a desktop that would not boot until i removed a stick led me to believe it was a bad stick, until it worked in other slots. it finally worked with 4 sticks once i inserted that 8gb fury, giving a total of 56GB RAM. it still would not work with the original 4, no matter what i did. i ran spinrite and had no errors. i was them hoping something was corrupt in the BIOS, so I updated it with the same results; all the original RAM works, just not 4 of them at the same time. i posted what i thought was a kind request for help, including the screenshots.

3 hours later YOU come by accusing me of...well, i still don't understand why people would pretend they have a IT business. are there REALLY folks out there pretending to be IT folks? what would be the benefit of that? all that prime pussssay falling from the ceiling just to get close to an IT guy??

i've been doing this stuff since DOS 2.2. sorry if i am not good enough for you. you seems SO ooffended i would respond in kind to you. is there a rule in the forum about taking abuse just because you have SO much cred? there are a TON of things i fall short in...thank god there are places like this, and that there aren't many out there like you to accuse me of...well, i stil don't get your post. maybe it's you?

PRIME Z690-P with 4 Vengeance 16GB chips. No boot

Corsair Vengeance has a bit of a reputation on user forums, which a good search will probably find.

Similarly, some people dislike Asus mobos, due (I believe) to poor after sales service amongst other things.

I have two recent Asus boards, one with a 3800X and four 16GB Corsair Vengeance DIMMs, the other with a 7950X and two Kingston Fury 32GB DIMMs. Both machines have 64GB total.

The old adage, two DIMMs are better than four DIMMs applies to many systems, especially when overclocking at XMP/EXPO/DOCP settings.

If you're having problems, disable DOCP and set the RAM back to JEDEC default (usually 4800MT/s for DDR5). If the system seems stable, boot from a MemTest86 USB stick and run a complete scan (several hours). Even with only one error, drop the RAM speed to 3800MT/s and run MemTest again.

Ideally, you should go out and purchase a single kit of 4 matched DIMMs, if you're dead set on running 4 DIMMs. If you buy two kits each containing 2 DIMMs, even if they have the same part number, they won't be exactly the same. The individual memory chips are "binned" and it's unlikely both pairs of DIMMs will be identical.

It's for this reason I bought 2 x 32GB Kingston Fury DDR5 DIMMs for my 7950X. I was lucky when I added two more Corsair Vengeance 16GB DIMMs to my 3800X, but they're only running a mild overclock of 3000MT/s. My DDR5 is running at JEDEC 4800MT/s. I value stability above speed and the kit is only rated at 4800MT/s.
