Solution for X99 & NVMe SSD issues
Solution for X99 & NVMe SSD issues
Hey everyone,
I'm really feeling uncertain about this situation.
Lately I upgraded my SATA SSD Samsung 850 EVO to an NVMe SSD Adata XPG Gammix S11. My system specs are: CPU i7-5820K, 8GB RAM (Corsair Platinum 2666MHz 4x4), GPU 1080 Ti, and a 1000W Superflower power supply.
I've been using the OC profile on the CPU (4,4GHz @ 1.26V) for about 8 hours in Rogster Realbench and all day in Prime95 at 26.6, which is not under AVX. It seems stable enough.
When I switch to default BIOS settings (stock CPU clock), everything works perfectly, so the drive itself doesn’t appear faulty.
However, if I change AI Tweaker to manual mode, the system becomes unstable. The BSODs I’ve seen are: critical_process_died and system_store_exception.
But these issues only occur during gaming (tested in SW Battlefield / Metro Exodus), after a few minutes of play, the game elements just disappear, making it hard to see players, followed by freezes and crashes.
I’ve tried leaving everything on auto, setting sync all cores at 40 and adaptive voltage at 1.25V, but the same problems persist. Even adjusting to 3.8GHz didn’t help; in games it was stable at 3.7GHz.
I’m quite puzzled—NVMe drives usually put less stress on CPU lanes, but this is different. Crystaldisk says the drive is fine, with idle temps around 39°C and load temps near 42°C.
I’m thinking about switching to a PCIe NVMe solution in the X4 slot for better performance.
Any advice would be greatly appreciated. Thanks!
When retiring an old PSU, ensure all modular cables are removed to prevent confusion about their non-interchangeability. This helps avoid accidentally damaging drives or other components.
The settings that control this are the ones you've already configured. I believe everything is set to auto mode, BCLK at 100mhz, and it's not using XMP. RAM speed is defaulting to 2133mhz for the X99 platform. I think the M2 chip might be putting too much strain on the CPU, but with a 5820k that has 28 lanes, I'm confused. According to the manual, the M2 is managed directly by the CPU (NB PCIE) and the X4 slot is connected to the PCH, so it should be handled by the chipset with PCIe 2.0. If the X4 is controlled by a different chipset, could this configuration improve performance? Using a PCIe card to connect to M2 might help.
You might need to refresh your bio, NVME was relatively new when the x99 was released. My NVME functions properly on my EVGA x99 Classified board, though it occasionally failed to recognize it during boot, requiring a bios update to resolve the issue consistently. Also, I have a question about how long you've been using that Asus board and what your current bios are. I recently got an Asus board and prefer it over mine, but I'm hesitant due to some concerns.
I had all the updates, drivers, bios ready. I tested the pcie adapter in every slot and adjusted the bios settings, but nothing worked. Origin & Steam took a few seconds and then a BSOD occurred. However, rog realbench, everything was stable after a full reset even with an OC. It turned out the problem might be with the PSU—I have an 8-year-old superflower 1000W golden king. I switched to another Corsair AX850 PSU and it fixed the issue completely, unlike my own PSU even with an OC. But now I’m a bit concerned because I needed a spare PSU to fix this, and I’m not sure if it’s gone or if it might come back later. I’m thinking about buying a Seasonic 750W focus platinum just to be safe, as some people reported GPUs/mobiles dying due to failing PSUs.
When retiring an old PSU, ensure all modular cables are removed to avoid confusion about their non-interchangeability. This prevents accidental damage to drives or other components like the GPU.
