I have a small overclock on my GTX980ti, Power Limit 130 / Temp Limit 91 (Priority) +100 Core clock and +385 memory speed. G.Just wanted to know if any one has had this issue themselves and has figured out the problem.

Not stability or a good OC (ex: your experience). Delete Kombustor and use something that stresses the GPU properly, like 3DMark. Higher temps will lead to lower boost clocks, so if you OC the core too much, boost can't dial 'down' properly within the same voltage bracket and becomes unstable. Why does it work like that? Because GPU Boost will already bring your clock to near-maximum, the cards come with a predefined voltage/clock curve and adapt on it based on temperature. When you reach the limit of stability, dial it back 10-20 mhz and put +300-500 mhz on Memory. Start with +0 Core OC, 95% power target and work your way up slowly - ONLY on the core overclock. Heat = current leakage = more voltage needed = more heat = GPU gets unstable. If someone had or have a problem like this or you think you may know the answer, I will appreciate some help. I tryed a few things like change software (afterburner to asus gpu tweak), reinstalling drivers, change power managment options in nvidia control panel,all makes no difference, I also look in bios for some power saving option, but everything looks fine.Ĭorsair 750W with gold standard ( i don't think it can be the power supply) If i set the vcore limit to maxium, frequency can get to 1940 in soft gaming, but with this card is not a option since it gets pretty hot.įor what i have seen gtx1080ti in theory can go at least to 2000 mhz. More interesting here is that the power limit do almost nothing, with 100% i can apply a +40 core and only +60 with at 117%. This card is well-known to rich high tempertures so when i amb playing the frequency starts at 1920-25 and drops below 1900 as the temperature get high. If i try +70 kombustor stress test crash in seconds.

My surprise comes when i saw that i coud only do a +60 core overclock with the power limit set the highest (117). Last month i bought a second hand gtx 1080ti (msi armor oc), i did some test and the card performed well (average with other stock gtx 1080ti by userbenchmark), i also bought a 4k monitor and i wanted to overclock the card for extra fps (needed in 4k, nowodays games are design to work with dlss).
