Help with Corsair RAM Speed/Timings for Ryzen 3700x (Crashes, Won't Boot)

the shadow on 09/07/2021 - 08:25

Hi guys, I have a RAM problem that I would appreciate help with.

I built a new PC last year, MSI MAG B550 Tomahawk + Ryzen 7 3700x + G.Skill Ripjaws V 32GB 3200 CL16 RAM with XMP enabled.

My PC would blue screen maybe once a month, and running Windows Diagnostic it would tell me I had a hardware problem/memory problem. So I figured my RAM was faulty - or at least one stick, as my PC seemed to crash every time it used more than 50% of the RAM (as observed in Task Manager).

It wasn't a major issue for me so I left it until now to purchase new RAM - Corsair Vengeance LPX 32GB 3600 CL18 RAM with XMP enabled to get 3600.

It worked for about 10 minutes then crashed. So I lowered it to 3466. It ran for about another 10 minutes then crashed - and then it wouldn't even boot into Windows or let me get into BIOS until I restarted it 20+ times. I finally got into BIOS and lowered it again to 3200, but it still wouldn't boot into Windows so I gave up and turned it off. Miraculously, after an hour, I turned it on and it booted straight into Windows.

It worked fine for half an hour at 3200 but then crashed again.

So I removed the new Corsair RAM and put the old Ripjaws back in. It worked fine for a few days and it let me do things that would usually cause it to crash in the past (using more than 50% of RAM). But Windows Diagnostic still told me I had a hardware issue/memory problem. But it worked, so …

But I think it crashed again during the night … so I want to try the new Corsair RAM again (as the Ripjaws may indeed be faulty?), but I'm a total noob and don't know what specific timings I need to set it as for it to be stable on my system.

Of course, I'm hoping the Corsair isn't faulty as well (or my memory slots?), and that I just need to use stable timings …

Both RAM are 2 x 16GB kits and I only used RAM slots 2 and 4 (dual channel). At the moment I can only think to lower XMP to 3000 and pray it works. But if someone has a better solution so that I can actually run the Corsair RAM at 3600 or 3200 that would be great.

Or can anyone tell me what the issue appears to be?

Thanks in advance!

    when it 'crashed' what did the 'BSOD' say?

    • the shadow on 09/07/2021 - 08:51

      These were the the BSOD errors I got over the months with the old Ripjaws (I took screenshots on my phone):

      Memory_Management

      System_Service_Exception

      PFN_List_Corrupt

      Kmode_Exception_Not_Handled

      Unexpected_Kernel_Mode_Trap

      Oddly enough, I don't think I got BSODs with the new Corsair. It just crashed (computer turned off/black screen) and restarted or I had to restart. :|

        are you overclocking?
        Could your windows install be corrupt?

        • the shadow on 09/07/2021 - 13:48

          I'm not even sure what overclocking is so I don't think so? Though I'm sure I read somewhere that using the XMP profile is technically overclocking? But I just want to use the RAM at its rated speed?

          I also very rarely play PC games. It usually crashes when I have too many Chrome tabs open + Steam running in the background or, yes, opening a game on Steam as well as having all my tabs open (using 16GB+ of RAM). ^^; So I usually close everything to play a game once in a blue moon and the game works fine without Windows crashing.

          Do you think, given the above errors and my issue with two different RAM sticks, that a Windows install could be the problem instead of the RAM? I use Windows 10 Pro. I can reinstall it but I really thought the RAM was the issue here. I haven't had any issues with Windows other than crashing during 50% RAM usage.

    Having issues with 2 different memory kits is very unlucky, its more likely its the actual dimm slots on the motherboard that is the problem.

    there is also a slim chance the psu is not providing enough juice to overclock your system. How many watts is it.

      I'm hoping it's not and I can figure out how to make the Corsair RAM work. But as it is … I'm still using the old Ripjaws now and it works just fine as long as I stay below 50% RAM usage. XD;

      I'm using a Corsair RM750x 750W 80+ Gold PSU.

      If it matters, I also have an Asus Dual Geforce RTX 2070 Super with one Kingston SSD and two Western Digital HDDs. But I've never encountered a problem with my GPU or drives. And my power seems fine - my PC has only struggled to boot (restarting loop) with the 3600 Corsair RAM, even at 3200 - but it always boots with the 3200 Ripjaws …

      Tech confuses me so. :(

    What PSU are you using?

    Also, if you've been messing with RAM timings, have you used this tool?

    • the shadow on 09/07/2021 - 13:58

      I'm using a Corsair RM750x 750W 80+ Gold PSU.

      That's the thing, I don't know how to mess with RAM timings at all. I've just done the very basic and enabled XMP profile/mode 2 and chosen one frequency (3600, 3466, 3200) but that's it. My PC doesn't like the Corsair RAM at all and constantly tries to boot into Windows but can't (constant restart loop), whereas it's OKish with the Ripjaws (currently using this … just need to stay below 50% RAM usage, haha).

      Thanks for the tool though - I'll have a look at it and see if I can make sense of it to try.

      • psyren89 on 09/07/2021 - 14:00

        Check the voltage on your modules and manually set them (or add 0.01-0.1V) instead of leaving it on auto? That'd be my suggestion if you haven't been trying to run aggressive timings.

        • the shadow on 09/07/2021 - 14:10

          My Ripjaws say 1.35v on them. So should I up it to 1.36 and see if it can go above 50% RAM usage without crashing, and if not, increase it again to 1.37 and so on to 1.40?

          And I don't touch the CL16-18-18-38 stuff?

          Sorry for being a noob. Thanks for your help BTW. :)

          • psyren89 on 09/07/2021 - 14:13

            @the shadow: Try manually setting it to stock first and see if that helps. If not, I'm not super sure how much you should increment it by each time to get it stable - I'd set a hard limit at 10% above the stock voltage, as I think anything above that is not going to help and indicates something is wrong with your RAM/mobo.

            Also, try running memtest to try to reliably reproduce crashes.

              @psyren89: This is going to sound dumb, but I haven't been able to figure out how to manually set the DRAM voltage in BIOS. I save it, but it never seems to reflect that it's been changed. -_-;

              It was set to "Auto" but on the left of it, it said 1.336V. So I changed "Auto" to 1.35V and I tried it with XMP enabled on Mode 2 and also with XMP disabled, but no matter what, when I go back into BIOS it states that my DRAM voltage is still 1.336V at the top (even though it still has my 1.35V value right next to it …).

              I also tried to run Windows anyway with XMP enabled/disabled (thinking maybe it was set at 1.35V but BIOS didn't reflect it for some reason), and every time my RAM usage goes beyond 50%, I get a BSOD error saying Memory_Management.

              But under 50% and everything runs perfectly fine. :|

              Any suggestions? Am I missing some steps?

      Thanks, I'll try to make sense of it.

    Windows installs can do some funky stuff.

    I had an install that hit the x570 chipset, making my 2nd NV<e drive really slow, and my TV tuner cards deliver corrupt streams on HD channels. After posting in a few places, everyone decided it was a faulty motherboard, so I packed-up the board, went and bought a new board, and returned the 'faulty' board.

    New board did the same thing. I was very annoyed, as you can imagine.

    Decided to image my drive, and re-install Windows fresh. All the problems vanished. I was rather annoyed, but set about setting up from scratch again.

    Only thing that I had issues with was trying to get a USB TV tuner working. Maybe the hodge-podge of drivers for that caused the issue. I ditched it and got out a pair of PCIe tuners instead.

    If you have a well-crafted install of Windows, imaging the drive allows you to install a fresh copy to test things, and if it still crashes, you can re-image your old install.

    Switch the ram to slots 1 and 3 (still dual channel) just using the 2nd bank channel rather than default. In bios set xmp to 1st profile (xmp 1) and leave all other ram based stuff to auto.

    DL Aida64 here run it and look at your memory (Motherboard/memory) and SPD to see timings brands etc it will also show if it really does support XMP mode

    Need further help PM me

    Do you have the latest BIOS for the mobo?
    Are the RAMs on the supported list?
