Nvidia GTX 1080 8GB overclock
Nvidia GTX 1080 8GB overclock
Hey there,
I'm trying my first overclock and decided to test it with my MSI GTX 1080 8 GB card.
I think I grasp what overclocking means. I've watched a few YouTube tutorials about using MSI Afterburner. A lot of them suggested raising the core voltage up to around a hundred, but I'm still figuring out where to adjust it properly. They mentioned that pushing the core voltage too high isn't ideal and that my temperatures spiked to nearly 89°C during testing.
I don’t really need to overclock the card since it performs well without any issues, but I’m really into this and want to learn more.
Am I doing it correctly without adjusting the core voltage? My settings show zero core voltage, power limit at 121, with a temperature cap linked to 92°C.
I have a custom fan curve, and my temperatures stay between 73°C and 76°C.
I'm currently running Valley Benchmark to check my overclock progress. I started with the core clock boost and managed to reach +150 without problems—anything higher caused a crash. I’m now focusing on the memory clock boost and have managed to get it up to +700 without any crashes. Is that typical? Do I usually see such high memory clock values? Am I doing something wrong?
Any advice or guidance would be really helpful. I also plan to improve my 3D Mark settings further. Thanks a lot!
It seems you performed a solid job, depending on the original boost clock setting.
Most Pascal cards reach about 2100Mhz in the core. The memory capacity is adaptable, but I haven’t noticed anyone surpassing 10,500 yet. A +700 boost is quite impressive.
The temperatures are excellent. If you’re happy with stability and overclocking, there’s no point in adding unnecessary extra voltage.
Yep, I kept the core voltage at 0. In Valley, my base core clock was 1987 MHz and the memory clock was 5005 MHz. The core appeared to reach a maximum of +150 on afterburner, which is now 2126 MHz. I stopped increasing the memory clock since that seemed excessive. So far in Valley, I haven’t noticed any problems, and I ran a test in Grand Theft Auto 5. I didn’t see any clear issues. There might have been some minor lag during certain loading scenes, but it’s unclear. I plan to try 3D Mark to check its behavior.
I’m maintaining a stable frame rate of 55 to 60fps on GTA 5 at 3440 x 1440 resolution (on an ultra-wide monitor). Should I continue raising the memory clock? And what duration should I run Valley to assess the stability of the OC? I let it run for about 20 minutes at speeds above 700 and didn’t encounter any problems.
It seems like you're doing great... I'd stay quiet if you're satisfied with the outcome. The results are solid, so it's best to go with what you've got!
Okay then, sounds good! I feel stable with it. I played GTA 5 for about 45 minutes without any problems.
Now my next question is... what performance improvement should I expect? And which settings should Valley benchmarks use to test it? The main reason I'm asking is because I have an ultra wide monitor that runs at 3440 x 1440 resolution. This setting isn't available in Valley, so I need to tell it to 'match system' to run at that resolution, as the maximum setting it offers is lower.
When I ran the base clock test versus the overclock test with adjustments on the core and memory, and set Valley to ultra while keeping the resolution at 'match system', my benchmark score didn't change much. Maybe around 1 fps faster for average performance, and my max FPS was about 3 points higher.
I'm assuming that since I plan to play in 3440 x 1440 resolution, that's the resolution I should use for the bench test, right? It just seems like I should be getting a slightly better frame rate boost then, yes?
Okay then, everything looks fine. I managed to play GTA 5 for about 45 minutes without any problems. My next question is about the performance improvement and the settings for Valley benchmarks. The main issue is that my ultra wide monitor runs at 3440 x 1440 resolution, but Valley doesn’t support that setting. I need to tell Valley to 'match system' to achieve that resolution, otherwise it limits the max resolution. When comparing base clock tests versus overclock tests with specific memory and core settings, the benchmark scores didn’t differ much. Probably around 1 fps faster on average, with a maximum of about 3 fps higher. I think since I’m going to play at 3440 x 1440, that’s the resolution I should use for the bench test, right? Should I be getting a slightly better FPS boost then?

Okay then, sounds good! I seem to be stable with it. I played GTA 5 for a good 45 minutes without any issues.
So here's my next question... How much of a boost should I be getting performance wise? And what settings should I have Valley benchmark set at to test it? The main reason I ask is, I have an ultra wide monitor that runs 3440 x 1440 resolution. This resolution setting isn't available in Valley. I have to tell Valley to 'match system' in order to run at that resolution, because the max resolution setting Valley offers is lower.
So, when doing the base clock test compared to the overclock test with the plus 150 on the core and the plus 700 on the memory and with Valley settings set to ultra and the resolution set too 'match system' so it runs at 3440 x 1440, my benchmarking score wasn't that much different at all. Maybe 1fps faster for the average, and my max fps was like 3 higher.
I'm assuming that since I'll be gaming in the 3440 x 1440 resolution, that's the resolution I should be running the benchtest, right? It just seems like I should be getting a slightly higher fos boost them that, no?
Use Superposition or Firestrike. Valley is a horrible GPU test as it's CPU limited. It's more a CPU benchmark now.
This is the first and only time I have heard of this. I'll def. look into it.

Great feedback:
I think it works well. I played GTA 5 for about 45 minutes without any problems.
Now my next question is: what performance improvement should I expect? And which settings should Valley have Valley benchmarks set to for testing? My main concern is that I have a very wide monitor with a resolution of 3440 x 1440. This setting isn’t available in Valley, so I need to tell it to ‘match system’ to run at that resolution. Because the maximum resolution it can offer is lower.
When I ran the base clock test versus the overclock test (with +150 on core and +700 on memory), using Valley settings set to ultra and resolution set to ‘match system’ so it runs at 3440 x 1440, my benchmark score didn’t change much. Probably around 1 fps faster on average, with a max of about 3 frames per second higher.
I’m assuming that since I’ll be gaming in 3440 x 1440 resolution, that’s the resolution I should use for the bench test, right? It seems like I should get a slightly better FPS boost then.
Use Superposition or Firestrike. Valley is a poor GPU test because it’s CPU-limited; it’s more of a CPU benchmark now.
This is the first time I’ve heard about this. I’ll definitely look into it.
It used to be okay… but with today’s high-end hardware, it’s mostly CPU limited. Heaven can’t compare, but Valley isn’t as bad as it used to be. 3D Mark benchmarks like Firestrike and Timespy are much better for GPU tests.
I would say that timespy and firestrike offer better overall system benchmarks because they evaluate many components of your setup. They provide individual scores for CPU and GPU, but you receive a combined result at the end... I like it. If you want to push your system further, try the 4k test...
