You're unsure about overclocking your MSI GTX 770 2GB.
You're unsure about overclocking your MSI GTX 770 2GB.
I've been using MSI Afterburner for almost a year now and have kept my settings at 100% power, prioritizing 80 temperature, with +130 core and +350 memory clock. I haven’t noticed any performance improvements, and there have been no issues with temperature or stability. I’m wondering if I might be doing something wrong, as the recommended values I see online are much lower than mine. I really want to get as much boost as possible without spending money on a new GPU.
What are your system specifications? A 12% increase in GPU performance wouldn't stand out if your CPU is the limiting factor.

Does this assist at all?

I attempted to overclock my CPU for the first time before, but the results were without any overclocking and I'm still confused about what to do. Even after running it, it reported 4.6GHz. I'm unsure if I set the correct voltages and that could be causing some problems, possibly linked to the overclock attempt.
It does. Let's start with the GPU. +130MHz isn't a massive jump overall. The base speed is already above 1000MHz, so the calculation makes sense. You'd likely see only about 5 frames per second, at most. It probably won't be noticeable in a game that's already running smoothly. A proper test might be needed to confirm the improvement—userbench doesn’t perform detailed GPU checks, but I think an extra 130MHz should show up even then.
Your CPU shouldn’t be limiting performance, though combining overclocking for both can still boost results. What concerns you about your CPU’s overclock? For a 4.6GHz setting, you’d probably have increased the core voltage somewhat. Can you explain what happened there?

Yes, it does. Let's start with the GPU. A +130MHz boost isn't much unless your CPU is the bottleneck. The standard speed exceeds 1000MHz, so the numbers make sense. You'd likely see only a slight improvement, maybe around 5fps. It probably won't be noticeable in a game that's already running smoothly. A benchmark might help confirm the actual gain—though userbench doesn't test the GPU thoroughly, I think an extra 130MHz should show up, even on that test.
Your CPU shouldn't be the issue, though overclocking both components together usually helps. What concerns you about your CPU overclock? For a 4.6GHz setting, you'd probably want to raise the core voltage a bit. What exactly transpired?
I'm not entirely sure what happened, but I adjusted the voltages based on a guide (which wasn't tailored for me). It could be coincidence or related to the overclock. I noticed loading times spiked dramatically, and I experienced in-game freezes where everything would stall for a moment before resuming. Sometimes the performance stayed consistent, other times FPS dropped noticeably. The only change I made was enabling XMP for my memory, switching "Disabled" to "Profile1" in BIOS. I'm not certain what that did.
At the moment, I don't have any CPU overclocking, and the lock-up issue persists. Should I push my GPU further or keep it unchanged?
Does the locking issue continue if you disable XMP? Regarding the card, a decent one can be boosted to around 1200, while a top-tier model might reach 1300. You'll only find out for sure by testing.
Your system details are being reviewed. A modest increase in GPU performance wouldn't stand out if your CPU is limiting speed. Let's focus on the GPU first. A 130MHz boost isn't significant unless your CPU is the bottleneck. The current stock speed exceeds 1000MHz, so gains would likely be minimal—around 5 frames per second at best. You probably won't notice it in a well-performing game. Running a benchmark might help confirm the improvement. Userbench doesn't thoroughly test GPU speeds, but an extra 130MHz should show up on that test.
Your CPU shouldn't be the main issue, though overclocking both components together can still boost performance. What concerns you is whether your CPU was overclocked. For a 4.6GHz setting, raising the core voltage would have been reasonable. The results were unexpected—long loading times and in-game freezes where the game seemed unresponsive for seconds before resuming. Sometimes FPS dropped noticeably.
I'm not entirely certain about the changes you made to your CPU. I increased voltages based on a guide that didn't match my needs, and I'm unsure if it was a coincidence or directly caused the issue. I also enabled XMP for my memory, switching it from "Disabled" to "Profile1" in BIOS. The effect of this change is unclear.
Currently, I haven't overclocked my CPU, and the lock-up problem persists. Should I push my GPU further or keep it unchanged? Also, does disabling XMP affect the locking issue? For the cards, a strong one can reach around 1200, while top-tier models might hit 1300—only testing will confirm this.
No, it's the final clock speed that matters, not the offset. You need to use the afterburner to check the actual speed you're getting. The standard boost clock is 1085MHz.
