r/OCCT on Reddit: OCCT 15.0.12 memory test crashes (Code: -1) at start

December 30, 2025 -

EDIT:

I installed Windows 10 22H2, and now all tests pass:

CPU (Extreme/Steady/SSE)
Memory (90%/AVX2/Auto)
CPU+RAM (Large/Extreme/Steady/AVX2/Auto)

So it looks like there was something in even the fresh install of Windows 11 24H2 that was preventing the OCCT Memory test from initializing. It would be nice to get to the bottom of this, but I am happy just to be able to validate my HW stability for now.

ORIGINAL POST:

System

I am unable to perform a Memory test using OCCT on this system. The result is always the same, 10 seconds of initialization and immediate crash with -1.

These settings were tried:

10-80% memory usage
SSE and AVX2
2 different RAM kits that are known to be good

Despite the memory tests failing, CPU and CPU + RAM tests PASS full 1-hour runs:

Large data set (CPU+RAM only)
Extreme
Steady
SSE & AVX2

Hardware

CPU: Ryzen 9 3900X
Mobo: Asrock x570 Taichi
Memory:
- Set 1: 32GB (4x8GB) DDR4-3200 CL14
- Set 2: 64GB (2x16GB) DDR4-3600 CL18
PSU: Super Flower Leadex VII 1000 XG
GPU: Radeon Pro WX 4100
OS: Windows 11 24H2 (Fresh install)

Does anyone have any thoughts or ideas? Normally it's the other way around, where the individual CPU and Memory tests pass, but the combined test fails. In this case, it feels like the Memory test is unable to start vs. failing due to system instability.

Try also with Prime95 the torture test with Larhe FFTs, usually on my system it detects an error after 5 minutes if ram settings are incorrect. In such case, try with looser timings in the bios and repeat tests or decrease mem frequency in bios until tests are stable and then increase until you get errors and scale back a bit to next lower frequency. Im some cases, you can try to increase voltage a bit for memory.

Re: i9 14900k randomly crashing - Intel Community

February 28, 2024 - Upgraded to a 1500W power supply to ensure sufficient power delivery, eliminating inadequate power as a cause. System temperatures and thermal performance have been monitored and are within normal ranges, discounting overheating as a contributing factor. Notably, the system crashes during two specific CPU-intensive tests: V-Ray Benchmark tool (when trying to test the CPU) and OCCT (OverClock Checking Tool), when inside the CPU test i chose the option for the "large" Data Set, suggesting a potential underlying issue with the CPU or its interaction with the memory controller, the motherboard or other system components.

OCCT power test issues - PCPartPicker

Here is the weird part, I replaced it with an open box 1200w RM1200x shift from Corsair and it works fine on the same simultaneous cinebench r23 and furmark stress test but I wanted to check for the psu stability. So I ran OCCT power test and my pc started getting errors after a few second, the test kept yelling ERROR ERROR ERROR, and the error counter was over 4 million (crazy right?) and then the pc rebooted just like before.

r/OCCT on Reddit: OCCT VRAM test detects errors - is this caused by hardware faults or buggy drivers?

May 22, 2025 -

Edit: SOLVED! I didn't realised the significance of this, but this is a small form-factor PC and the GPU is connected to the motherboard via a PCIe x16 riser cable that came with the case. The riser cable is gen 4 while the CPU and GPU can handle PCIe 5.0. The motherboard automatically set the PCIe link speed to gen 5 but the cable couldn't handle it.

What OCCT was detecting was compromised signal integrity resulting in errors during the VRAM test and the drivers crashing during the 3D test.

Manually setting the link speed to Gen 4 in the BIOS fixed all the issues I mention below.

TLDR; not hardware fault nor graphics drivers - just an older gen cable.

___________

I built this PC two weeks ago and immediately encountered problems playing recent video games (screen freezes or game crashes to desktop within minutes of starting a game) but strangely older games appear to run fine. I’ve experienced a couple of instances where the GPU stops responding after the PC boots up, but otherwise no other graphical issues during regular PC use.

OCCT has narrowed the problem down to my graphics card.

3D adaptive test crashes with the following text: Test cashed (Code: -1)
VRAM test reports error within 2 - 15 minutes of starting the test.

Screenshot of the number of VRAM errors detected. Not pictured: the look of horror on my face.

In both tests, Event Viewer reported an nvlddmkm error (ID 153) having occurred at the moment the test crashed / errors reported.

Does this information point to hardware fault or graphics driver problems?

This is a brand new card, so still under warranty!

First, I want to thank you for the detailed info about your system. It answered my first question. Second, have you tried any other drivers for your 5080? I see you are on the latest studio driver. Do these issues happen on Game Ready, or older studio drivers?

[SOLVED] - OCCT Memory Test crash | Tom's Hardware Forum

June 17, 2020 - While using OCCT to establish a baseline of the current status of two sticks of DDR3 memory, OCCT immediate 'crashes' when I start the test. This is not a computer crash. The OCCT software crashes. It says 'Crashed' on the screen with no results. NOTE: The computer is running fine (no crashes) and some testing of the temperatures with OCCT are mostly in the normal range except for the GPU.

r/OCCT on Reddit: CPU Test Instant Crash

July 25, 2021 -

I've been encountering sudden, no-BSOD restarts with my pc. These restarts started only a month or so ago at most, and occurred at seemingly random times. Some crashes occurred while playing Minecraft or other games, some while having web searches open, and some while just sitting on the desktop with no actions taken. These crashes create no Memory dump files and the event logs only say "fatal hardware error has occured".

I have been able to replicate this restart using OCCT. When running the cpu test, the computer shuts down within 1 second of starting the test. When I run the Power test, a crash occurs within 30 seconds. The Linpack test fails after a few minutes, though I haven't really tried to reproduce that since the other two failures are so fast. All other tests (memory, GPU, VRAM) all complete successfully (which in the case of the memory test means 100% cpu load is not directly the issue).

After research, I have replaced my power supply (650W->700W), reseated my RAM, and updated the BIOS but none of these fixed the issue. My gut says it's a CPU or Motherboard hardware issue, but I'm not sure. Can anyone here can offer advice, or at least some idea of why the cpu test would crash before the cpu can really gain temperature/load?

CPU: RYZEN 5 3600

MotherBoard: MSI B450 Tomahawk Max

GPU: EVGA GeForce RTX 2070 Super (08G-P4-3071)

PSU: Corsair CX650M (replaced)->Coolmax ZX 700W

EDIT: Well, looks like things got worse. I went to grab food and now my pc is stuck in a "Critical Process Died" BSOD on boot, and my restore points don't work. I don't even know what to think now

Check Event Viewer. Event Viewer is built into Windows and takes logs of all system events that happen. So when your PC randomly restarts, check it. My PC was doing the same exact thing, just restarting without a BSOD and I would BSOD once every single day. I fixed it by lowering my ram from 3600 (which was T-Force DDR4 4000) to 3200, and I swapped my headset from front panel USB to motherboard USB. If you have something plugged into your front panel (aka case) USB, that could be the source of your issues. Edit: Just realized that you did check Event Viewer. It’s also worth noting that my system also always failed to create dump logs. Check device manager and see if a USB device has a driver error, cause if you have something plugged into your front panel USB that may be causing it.

Did you have a manual overclock in your 3600? If so, what load voltage were you running normally?

Using OCCT libraries application "Debug Assertion Failed" on Windows - Forum Open Cascade Technology

So, the first step is to check if Debug DLLs from OCCT are used with your Debug library (you may notice that there are no Debug libraries within official OCCT 7.5.0 binaries!). There are some fragile tricks allowing to mix Debug/Release CRT in application, but in general this combination should be avoided. Structures like std::istream and FILE have different definitions in Debug/Release builds within MSVC CRT, which leads to crashes when passing object created by another CRT - and this is only one of examples of possible clashes.
