Just received the latest model, but games are still failing to launch.
Hello! I recently assembled my first PC and have been struggling with 3D mark graphics tests, often experiencing crashes. This issue also affects games such as Elden Ring and Overwatch – whenever I launch a game, it freezes and crashes within minutes. The Event Viewer suggests the problem might be linked to nvwgf2umx.dll, but graphics updates and DLLs don’t fix it. Outside of gaming, everything functions normally except for occasional BSODs and system instability when using Chrome. I’ve attached my PC specifications and the list of tests I’ve run below.
CPU: i7-13700k (sourced from eBay)
GPU: ASUS Dual GeForce RTX 4070 (supercharged)
RAM: gSkill Ripjaw DDR5 6800MHz 2x16GB
Motherboard: MSI Tomahawk z790 Wifi DDR5 – open box from eBay
Storage: Samsung 990 Pro 2TB AIO
Case fans: 4x Corsair AF120
Power supply: Corsair 750e
Operating System: Windows 10 Pro
Tests completed: GPU temperatures stayed under 60°C during load; drivers were rolled back to an earlier version. Disabled Wi-Fi and DDU drivers in safe mode, updated drivers locally (WiFi still disabled). Verified all electrical connections and re-seated the GPU. I installed the GPU in a friend’s system – it worked. I also tried installing the GPU and an SSD in their system – both functioned correctly. RAM performance was normal except for Database Operations, which failed during Memtest86. RAM slots 2 and 4 were confirmed correct. I disabled/activated XMP settings and tested various RAM speeds (6800MHz, 5600MHz, 4800MHz, single stick vs dual). I also experimented with different RAM modules (Corsair Vengeance RGB DDR5 6000MHz).
Let me know if you need further guidance!
Remove the dedicated GPU and test a few games using the integrated graphics. If issues persist, check for incorrect pins on your motherboard's socket. Then, consider using the 4070 in a different PCIe slot that powers through the chipset instead of the CPU core. You might also try reducing the PCIe bus speed to 3.0 for PCIe_1.
I've run some tests with the iGPU and haven't encountered any crashes, though not thoroughly. Some users report that memory instability can lead to driver issues. If this applies, would you notice it on the iGPU itself? I’ve downgraded to a PCIe 3.0 bus but haven’t succeeded, and I’m limited by the case’s space, so I might need to rebuild the system outside the enclosure for testing.
Do you connect your 4070S using the original 12VHPWR cable, the factory adapter, or a modified aftermarket version?
I'm using the adapter that came with the GPU. It's a two 8 pin to 12VHPWR adapter. I've noticed many reports about the connectors not fitting correctly, and that's true... Based on that, my friend uses an EVGA power supply where all 8 pins are connected. My Corsair PSU only connects 7 or 8 pins. According to their documentation, they didn't wire the Voltage Sense pin. I'm sure Corsair understands what they're doing, but it caught my attention. Unfortunately, Corsair uses different cable connections for their PSUs compared to EVGA, so I wasn't able to test my PSU with their cables.
I'm sharing my insights after dealing with various aspects of 12VHPWR, from multiple native power supplies to the adapter and cables. If your PSU is a type 3, you can utilize the internally adapted 2x8pin to 12VHPWR cable, though using the factory adapter might be more stable. I've noticed similar challenges with my RTX 4090 when using adapted cables alongside native 12VHPWR. This could be less applicable to your setup, but it's worth noting given how the dGPU's AUX power connector is set up—only recently has this become a concern with 12VHPWR.
I have a friend who owns a Corsair 750 watt power supply, and I plan to test it in my build. It would be great if it functions properly and I can return the power supply afterward.
I successfully checked another power supply, but the issue remained unchanged. This narrows it down to the CPU and motherboard. I’m risking it by sending back the motherboard, as it’s simpler to return, and I hope upgrading it fixes the problem.
