Hello,
I've been facing some challenges with my GTX 1070 for a while now. It hasn't been easy to get it to overclock consistently using MSI Afterburner, and I've recently observed some drops in FPS during gameplay. I'm curious if this is connected to the card's voltage or whether my power supply isn't providing enough power overall. Every time I play a game, the card seems to reach its voltage limit, as confirmed by both Afterburner and HWmonitor. The maximum voltage I can extract from it is 1.063, which might be on the lower side, though I'm not sure if that's accurate. Regarding the afterburner settings, I haven't pushed it overclocking technically. I've adjusted the fan curve, raised the temperature threshold to 92°C, and pushed the power limit as high as possible (only reaching 105%). However, whenever I experience those occasional FPS drops—especially after long gaming sessions—I tried increasing the core voltage by 10%, but it didn't help. I then reset it back to normal. What's puzzling is that my clock speeds remain stable during these drops. If this were a power issue, wouldn't there be a noticeable slowdown? I suspect the problem might lie with my power supply since 500W seems a bit low for my setup (it was a pre-built PC), though I'm not certain.

I also have other concerns about my overall performance. In the past, I've overclocked and achieved only modest gains despite higher clock speeds. I'm wondering if similar factors—voltage or power supply—are affecting both my overclocking results and this FPS issue.

Please feel free to ask any additional questions; I'll do my best to address everything.
Computer specs below:
Motherboard: MSI Z170A PC Mate
CPU: i5-6600K (not currently overclocked)
GPU: MSI GTX 1070 Aero
RAM: 16 GB 3000 MHz GDDR4 (G-Skill)
Power Supply: 500 W (EVGA)

Thank you.

Your PSU is more than enough, you might even fit a 1080ti inside and still worry about lacking sufficient wattage for that setup.
Pascal GPUs from the 10xx series don’t seem to be affected by voltage when it comes to overclocking.
I can push my 1070ti up to 2GHz without increasing voltage, which seems to be typical. Just hit the power limit and check how far it goes.
GPU cards include a GPU boost 3.0 feature that adjusts the GPU speed based on available power and temperature—maximizing power is often more effective.
Manually overclocking your card is straightforward, safe, and can push performance beyond what GPU boost 3.0 offers.
Don’t just focus on GPU memory either; improving it can boost FPS, but you’ll notice artifacts or crashes in games eventually. So try to optimize both at the same time only after confirming stable clocks for both GPU and memory.
