Ram Compatibility?

[MagicalDuck]

I asked this in the troubleshooting page, no one seemed to reply, I figured I must've asked it in the wrong section, so maybe any of you guys might know what's up.

Motherboard: MSI x470 Gaming Plus
CPU: AMD Ryzen 7 2700X
RAM: G.Skill RipjawsV DDR4 32GB (4x8GB) 3200MHz
Windows 10 (Any version, same errors)

I have 2 kits of 2x8 ram sticks, so in total 4x8. Google does say that RipjawsV work with 2700x, but I never actually got it working stable. I keep getting BSOD, yet only when using 4 sticks. All 4 sticks of ram work in any slot of the motherboard, tried it one by one, 2 sticks in black slots, then 2 sticks in red slots, and even with 3 sticks, one without being paired - works fine. But the moment there is 4th one, I keep getting a BSOD. I updated everything that was possible to update, re-installed windows 4 times by now, tried the newest version of Windows 10, and a few others, dating back to 2015 version. After 4th stick is installed, I am getting a lot of crashes, from Direct X related, to "Memory_Management" and so many others. All the parts are brand new, and I am currently using 2 sticks of ram for the past month without any crashes. With 4 sticks installed, system works somewhere between 30 seconds and 12 hours (yes, it held up quite a few times for about 12 hours). I even changed the PSU to a way more powerful one, from a 500w one to a 850w one, as someone suggested that MB might not get enough power. I did try to change the voltage of ram a few times, change the speeds, nothing seemed to help, or I didn't find the right combination of both. Currently it is running at 2133MHz with 2 sticks installed. I even thought they might overheat, bought way better case coolers for this, and now everything stays nice and cool inside - still did not fix anything.

When it did work for 12 hours, I did benchmark everything, all 32 gigs of ram worked perfectly when using them at a 100%, even when using CPU at a 100% at the same time. Then I might be just browsing YouTube, or literally doing nothing, PC could be just idle - and it would blue-screen randomly.

A few of blue-screens I am getting are "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED", ""KERNEL_SECURITY_CHECK_FAILURE", ""APC_INDEX_MISMATCH", CRITICAL PROCESS DIED. Every single time it does blue-screen, it pretty much always is a different one. Seen about 20 different ones by now. Every single driver is up to date, tried updating them in every Windows 10 version I tried.

I'm out of ideas by now, nothing left to update, out of money to buy another ram or another MB. All I know that I bought 32 gigs of ram, and I can only use 16 of those. Yet no matter which ones, they just don't work as a 4 stick kit, for some reason. Anyone have any clues or ideas what do to?

hmm, do all 4 kits work on other PC? sometimes you need to have a matched set or something

I think it is the mob or gpu or a bad ram stick

I did say, that I tried them 1 by 1, I let every ram stick work for ~24 hours as just 1 stick, no errors in each of them.

Then its the mother board or cpu

Try running the RAM at the auto-frequency determined by the BIOS. I had the same problem but now I just run my 3000mhz kit at 2600mhz...

Hard to tell, I already took them for a warranty change, got a whole other 2 kits of same ram, it did not seem the problem as with these that are replaced, same errors occur. For the store I bought them from, it worked fine, yet they insisted they test it on their own PC's, for them they worked for over 48 hours as a kit of 4. I am pretty sure they used Intel MB though.

perhaps its a mobo issue. test 4 sticks of different ram from a friends pc or something?

Is there a BIOS update on MSI's website? If so, try that. It might need an update.

I did try that, I even updated the bios and left everything on auto, still did not fix anything. I got the processor checked, MB and ram - all of them are in perfect condition. They just don't seem to want to work as one. That's why I changed the PSU, as I figured it might be the the underpowered MB, turns out not.

Currently running the newest BIOS version, even tried older ones, none of them fixed it. I've been trying to figure out this for more than a month now. Pretty much nothing left to update or even try older versions, as tried in every category I could think of.

Try changing the voltage allowance on the RAM (if you can). It might be something to do with the CAS timing. Have you tried with a different set of RAM to check everything else is working? Might be worth asking MSI which RAM goes best with the mobo.

This is the only thing I haven't tested. Don't know anyone who uses DDR4 overall, let alone that would be compatible with 2700x. The other option is to buy a new set of ram, yet if that would also not fix it, that's just money down the drain. So I want to try every possible solution before going the "money path".

Did ask MSI themselves, I tried everything they asked me to do. The only solution left with them, to send the MB directly to their warehouse to some other country, and that would take ~a month for it to proccess. I can't live without a PC for a month, as I am working from home. Haven't tried other set of ram, no one I knows has the ones that would be compatible with my PC. And not sure about the voltage allowance, after messing with this on my older PC, I managed to ruin the ram overall.

You say it's the insertion of a fourth stick that causes the BSOD. Is it consistent with the same stick / memory lane? Or is it just 4 sticks generally?

It's 4th stick in general. Any of them could be the 4th stick, and it will cause a BSOD. They all work when inserted as 1, and all of them work as kits of 2. Even works when I have 3 sticks installed.

That sounds like the motherboard is struggling here. It might be a dumb question but do you have anyone with an AM4 motherboard / CPU to test if either of them are faulty? Try explaining to MSI that the problem is with the board and you want a replacement as you can't do without your computer for a month. If they refuse go down the "loyal customer... very disappointed... wouldn't recommend... you've just lost a customer..." route, that sometimes works...

I did explain that to them, and they won't send a replacement after they received this one, and tested it out themselves. If it turns out that it's fine for them, they'd send it back to me, and I'd be at square one, yet losing a month of work and money. Don't want to risk it. The last option I currently have is to take my PC to a repair store that I know is going to be expensive, if no one else had this problem like me, and wouldn't be able to help me. Never actually even had to ask for help on forums, I was never this lost with my own PC in my entire life.

Buy a budget AM4 motherboard, like an ASUS or ASRock B450, to fill in for while your other motherboard is away. When you get it back either return or flog the budget one. RAM incompatibility really sucks because it's petty and stupid but ruins everything. I hate it.
