BSOD on sppsvc.exe
BSOD on sppsvc.exe
I experienced multiple BSODs pointing to sppsvc.exe, unsure if they stem from a hardware fault or a software glitch. I observed that reducing the base clock (BCLK Frequency) from 100.0 to 96.0 significantly decreased the frequency of these crashes. The dump files are available here: https://www.mediafire.com/folder/bjsccu08nqi42/dump. My system specifications include an i7 13700k CPU, Asus ROG Strix B660-F motherboard with latest BIOS, 2x8GB Kingston DDR5 RAM at 6000MHz, MSI RTX 3060 Ti GPU, Corsair H150i Elite Cappelix cooler, a 1 TB Kingston FURY Renegade PCIe 4.0 NVMe M.2 SSD for Windows 11, an XPG S41 TUF SSD for Linux, and an XPG Core Reactor 850w PSU.
Hello, and thank you for joining the forum! Based on the clues in your dumps, it seems the issue could be with the RAM. I recommend starting by testing the RAM at its standard speed (4800MHz) for a short period to check stability.
Thank you! I attempted to run at XMP disabled (4800MHz) and also with the 4800MHz profile active, but at 100 BCLK it remained unstable. It appears the frequency isn't the main issue—it's more about another parameter that changes with BCLK. For example, setting it to 6000MHz but using 96 BCLK stabilized the system. Also, testing the RAMs in memtest86+ on the BIOS showed no errors.
I tend to favor Memtest86 (free), though no RAM tester can guarantee 100% accuracy. Still, assuming your RAM is fine now, altering the BCLK might change the symptoms, suggesting a hardware issue is likely. I recommend resetting all clocks and voltages back to defaults before proceeding, then download and execute Prime95.
If you're unfamiliar with Prime95, it puts stress on your CPU and RAM, potentially causing overheating. Therefore, use a temperature monitor such as CoreTemp to keep an eye on CPU temps.
Execute all three Prime95 tests—small FFTs, large FFTs, and Blend—for at least an hour each, extending the duration if possible. If errors appear, or if the PC experiences BSODs or crashes, or if CPU temperatures surpass 98°C (your CPU’s Tmax is 100°C), halt the test and inform us of the outcome.
A stable CPU with proper cooling should run Prime95 without issues indefinitely.
I attempted to execute Prime95 using stock configurations, but it crashed almost immediately. Re-running it triggered a PC crash with the error "MEMORY_MANAGEMENT". The system responds quickly to BSODs even without stress testing. I've attached the dump file: https://files.catbox.moe/20odm4.dmp
It seems like the issue is likely bad RAM. Try disconnecting one stick and running it on the other for a while to trigger a BSOD. Then swap the sticks back and run it again to confirm the problem. If each stick causes a BSOD independently, the RAM may be faulty.
If that doesn't happen, consider using the Intel Processor Diagnostics Tool to check your CPU status.
I attempted this last week but although it didn't trigger a BSOD, it crashed Cinebech immediately or after a few tries. This is typical when the PC becomes unstable. I tried each RAM module and swapped slots, but nothing resolved the problem.
I ran the Intel Diagnostic Tool yesterday with default BIOS settings (100 BCLK) and it reported no errors.
I have some questions that would be very helpful:
1. The RAM isn't listed on the QVL from the motherboard, does this suggest it might not work even with standard settings or could indicate a fault?
2. The issue began after a BIOS update. According to the manufacturer's site, rolling back the update isn't possible. Could this be a compatibility problem between the board and RAM?
3. On HWiNFO64 each RAM stick is operating at different voltages, even when XMP is enabled and BIOS is set to "Sync All PMICs". This seems normal? Please see the screenshot:

The QVL includes RAM that has been tested and confirmed compatible. RAM not listed may still function, but it could also fail. It's best to use RAM from the QVL to prevent compatibility issues. We can't be certain if your RAM is incompatible. You should consult the manufacturer about whether a BIOS update might be the issue. It's usually safer to check with the board vendor before updating their BIOS. My intuition suggests this isn't the main reason for your problems.
Make sure your RAM is in matched pairs or comes from the same vendor with identical part numbers. Mismatched RAM often causes numerous issues and crashes. Always purchase RAM as a set of matched sticks. If the voltage levels differ, they aren't a proper pair, which likely explains your problem. The only solution is to discard these two sticks and replace them with a matched pair.
They were suppose to be matching cause i bought the kit 2x8 GB from Kingston (KF560C40BBAK2-16), but even on stock settings they still have differ in 0.1v-0.2v.
So i am gonna try to contact Kingston to see what we can do about it, it is still on warranty.
I found a few points to note:
1. Keeping my CPU power capped around 200W allows me to boot and perform stress tests without crashes or BSODs, though the PC shuts down afterward. Disabling turbo and running at base clock works just as well.
2. The stock "VRM core voltage" is 1.465. Videos show lower values like 1.38 and even 1.28 at stock settings, with a drop to 1.16 when BCLK is reduced. Is this normal?
3. Changing the microcode to "0x104 Microcode" in BIOS improves stability at 100.0 BCLK, enabling stress tests even with high RAM speeds. However, it still causes errors in Prime95 and some crashes overall.
Could these issues be related to temperature or motherboard problems?
