RAM (or mobo?) problem

[Mountain Circuit]

Hello!

I have a problem were I boot on only one ram stick but not 2, 3 or 4 sticks in. I have tried all of my ram sticks, one by one, in all slots (Link to my sticks: https://www.kingston.com/dataSheets/HX426C16FB3AK2_16.pdf (4x8 Gb) ). My rams are "different" from each other, bc 2 have tiny more of a bold font then the other 2 sticks, but it is the same sticks. I have tried all different combinations with my sticks and it boots with all my sticks but just one at a time. My brother has tried my sticks on his motherboard, and he can boot with 3, 2 and 1 sticks but it is one "false" one that dosent work on hios motherboard. I can boot with it on my computer btw.

I have also tried with my brothers ram sticks(2x8 Gb crucial ballistix) and it also boots with one but in a weird way. I have inserted his two ram sticks in my slots and it boots and BIOS recognizes two sticks but windows does not. Both are lit up but only one is recognizeble in windows, and I have tried to switch place but then it can't boot.

I have also tried to update bios and I have tried memtest86, but 0 errors.

Could you guys give me someting cause I have red this (https://linustechtips.com/topic/1050400-pc-only-booting-with-one-ram-stick-not-two/), and he just switched his motherboard. I wonder if you can give me some tisp that i can try before i get rid of my botherboard.

 

History:

When i got it (prebuilt) it was fine with all four sticks. Then after some time(a year or something) when I loaded cod, my RGB started to lag. Later (I dont remember when..) I couldent boot with 4 stick in. I could remove one stick and it was fine, but i decided to run on two sticks just in case. But now when we(me and by brother) took a look on this problem (why I could not put 4 sticks in) it wouldn't boot with any but one of my sticks and or both of his sticks. Right now I am running on both of his sticks (but only 8 Gb, not 16).

 

Specs:

mobo: Rog strix z390-F Gaming

Cpu: i7-9700K

GPU: NVIDIA GeForce RTX 2026 Super

RAM: read above ^^^

Thank you for your time if you help

Weird. Do you know if your chipset and BIOS firmware are up-to-date?

Yes, they are... Do you have any other ideas?

Right now this is beyond me right now. I assume you're seating your RAM correctly (not seated well can cause problems like these). But other than that, it sounds like a motherboard problem.

 

From what I read, your memory is on ASUS's QVL, so it should work.

 

When you say it won't boot, do you mean just into Windows? Does it boot into the BIOS/UEFI and recognize the ram?

 

If Windows doesn't recognize them nor boot, but the BIOS/UEFI does, then maybe it's a Windows problem. In that case I'd try to reinstall Windows.

 

If the BIOS/UEFI doesn't recognize them even when seated properly, then maybe it's either an internal motherboard problem, or there's something wrong with the slot/seating connection.

 

Another thing to look at is RAM settings in BIOS/UEFI. If set to a too high speed or too high or too low of voltage, then you can have problems. Usually stock settings should work fine.

It won't boot into bios or windows and the DRAM is lit up, so do you think it is the mobo? I have red that it also can be the cpu, but what do you think?

I'm not an expert, but if you tried the RAM then maybe try the CPU next, and if that doesn't work then the whole Mobo. I think the main thing is to get something you can return (something that doesn't cost you to return) if it's not the fix, and to try to start with the cheapest fix first.

Thank you. I had plans on upgrade my PC, so I think I'm gonna do that now

Yeah, sorry this problem may have rushed your upgrade a bit.

 

I've had similar problems. My last desktop, a 2nd Gen Intel with quad GPU's, started to bluescreen daily, and I couldn't figure out what the problem was. I tried testing and swapping RAM, tried fewer GPU's, tried switching out the CPU, but nothing worked.

 

In the end I decided to just upgrade to a 12th Gen Intel system with integrated graphics that I put together, and so far it works great.
