ASRock z370 Taichi with two GTX 770's

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello all,
I just recently purchased the ASRock Z370 Taichi and paired it with a 8700K. Due to the cryptocurrency craziness, I'm obviously not going to purchase a new graphics card anytime soon. So I've decided to use my current GTX 770's in SLI. As expected from my post, I'm running into an issue. Every time I benchmark or play a game, within either 10 or 15 minutes of benchmarking or gaming, the game or benchmark freezes. I can simply press ESC and both the benchmark or game closes. Now if I just have one GTX 770 installed, the benchmark and games run perfectly fine for hours on end. I've tried both cards in slot one and each successfully ran the benchmark and games just fine. These lockups are only occurring when both cards are installed with SLI. I've tried different SLI bridges. I've uninstalled and reinstalled drivers. The BIOS is updated to P1.40 and set to defaults.

Specs:
Case - Corsair 570X
ASRock Z370 Taichi - P1.40 - default BIOS settings
8700K - no overclock
Corsair H100i v2 CPU cooler
G.Skill Ripjaws V Series (2 x 8GB)
Samsung 850 Pro 256GB SSD
Corsair Gold AX1200 single rail PSU - 8 years old
2x EVGA GTX 770's - 390.65 drivers
Windows 10 Pro

Curious if anyone has experienced this or has some insight?

Much appreciated!

	I reverted back to P1.30 as suggested, yet still getting the freezes unfortunately. Event Viewer shows these errors after it froze running the 3DMark benchmark: Error: The description for Event ID 13 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

	Did you use DDU (Display Driver Uninstaller)? Is this a fresh OS install?

	Did a fresh OS install just now with both GPUs installed. Let Windows automatically install all the device drivers. After all the Windows Updates, I only installed 3DMark. Selected a benchmark and maybe 3mins into the test, it froze. I'm wondering if the second PCI-E slot is faulty. When I put one card in the first PCI-E slot, no freezes. When I put one card in the second PCI-E slot, the benchmark freezes.
