Overclock info please
Overclock info please
Hi,
I was wondering about the best approach for overclocking from scratch. Should I begin with the core and then move to the memory, and once the core hits its limit, should I adjust the other settings? For my MSI GTX 1080, it seems the default setting is 110 on the core when benchmarking at 1920x1080, so I’m unsure whether to boost memory or change the core voltage instead. Thanks!
The question about a fried card is worth considering. You'd likely need more voltage than the card supports (such as the RMA requirements from Nvidia, which limit how much you can add) or allow it to exceed its temperature limits for extended periods. I don't know the TjMax for the 1000-series, but it's probably not 60-70°C—likely between 85-90°C.
I own a GTX 760 that I've used for two years, and my brother used it for another two years. I overclocked it quite a bit from the start, reaching around 80°C during gaming. It's still functioning normally inside my PC, operating just fine. I've played games on it while doing crypto-mining with an AMD card. The 760 can handle Elder Scrolls Online without issues.
Assuming you're only adjusting your GPU, begin with the clock settings and check for stability. Then increase the memory settings, starting around +150 on clock and +500 on memory, monitoring temperatures and customizing the fan curve for better cooling. Gradually raise the clock by +10 at a time, though significant improvements are unlikely. I haven't seen anyone reach +200 successfully. You might still gain more FPS from memory tuning.
I haven't noticed significant improvements from memory OC, probably only 1-2%. Core performance is much higher, reaching up to 10%. I run games like Unigine Valley, Heaven, or Superposition and look for artifacts or lockups to ensure stability. As a quick check, I play for a few hours or days. If issues arise, I reduce the clock speed by 10-20 Mhz. It usually works well at that point.
Hi,
Thank you for your message. As I've already mentioned, when using +110 on Core Clock alone during Heaven 4.0 at 1920 x 1080, the driver crashes and recovers quite often. Is this normal behavior or am I really unlucky with the Silicon lottery?!
I haven't adjusted core voltage or memory clock yet. I'm a bit frustrated because with just 110 on the core and nothing else changed, I can't complete the Heaven bench test.
I haven't ever set up a custom fan curve and feel completely unsure about how fans in Afterburner should be handled. My current settings were: 85 Core Voltage, 100 Core Clock, 495 mem clock. I was getting a score of 3190 on Heaven at 1920 x 1080 — is that a decent result?
I also tried Crysis 3 with maximum settings at the same resolution, and I played for about 25 to 30 minutes before crashing again. Now I'm told that starting at +150 on Core and 500 on mem from the beginning should work, which suggests my setup might not be optimal for this machine.
I believe my MSI GTX 1080 Gaming X Plus is clearly a poor representation of the hardware I have.
Be prepared to increase voltage whenever you OC. At least in the core. I'm not sure if Nvidia still restricts voltage at a low level. The 760-series performed poorly for boosting voltage. The stock was around 1.17v with a max of 1.18v, unless you got that one special card that cost about 200 dollars more. In short, those cards didn't come with a voltage regulator.
Increase the voltage limit slider to its maximum. This might be resolving your clock problem.
Thanks again! I plan to try later and raise the core voltage gradually, following the 25mhz increments, to discover what happens.
According to the previous post, if I can start at 110mhz core and 500mhz without raising the core voltage, I think I might be in trouble!? A friend also mentioned that since it’s factory-set, the RMA option isn’t viable either because there’s nothing technically wrong with it!?
I’m starting to get worried—lol!
I usually just push the voltage limit up to maximum before trying +100 and +500, so I wonder if keeping it at the normal voltage will give me stable performance.
Hi,
Everything is at its absolute maximum for core voltage, power limit, and temperature. At first everything seemed fine, but then I noticed something strange. When running at 110mhz with the core clock, I got a score of 3041, which dropped to 3038 at 115mhz. I've also tried 120mhz and experienced driver crashes, only to recover with a minimum FPS of 5.1!
It’s still happening even when I go back to 115 or 110 MHz, which makes me think something is wrong. Some reviews say a boost of 2000MHz shouldn’t be too tough, but with my card it feels like an impossible task!
I’m really confused. My highest stable core clock seems to be around 100mhz or lower, even though the core voltage is set to its maximum.
Please let me know if you have any other suggestions—I’d really appreciate them!
