GTX 1080 TI strix hitting power limit on benchmarks

post #1 of 3
Thread Starter 
I haven't overclocked a GPU in a long while, and I'm completely new to Pascal, so please correct me if I'm wrong but I was watching a simple overclocking guide to overclock pascal based GPU's and one of the points made was that the card should not be hitting the power limit at stock. Unfortunately that's exactly whats happening to me.

I ran both heaven and firestrike and both benchmarks caused my 1080ti strix to hit it's power limit. I followed up by unlocking the power target slider, unlinked it to GPU temp and set it to 120%. This appeared to ever so slightly reduce the number of times I hit my power limit but it still does quite often in the same benchmarks.

Now my question is, is this normal? I haven't overclocked the card at all, from my understanding, this shouldn't be happening unless I overclocked the card in some way?

Temps never hit above 65C and my top core speed was 1911 Mhz (for only a few seconds). Thanks in advance. smile.gif

Small follow up question. If this is normal, will it affect my overclocking potential, and is it any indication of the quality of silicon the GPU was made with? (Bin quality)

Just an update, I may have answered my own question but I want to post it in case anyone else was experiencing something similar. I did notice something peculiar while running benchmarks yesterday. While my power limit might be reached doing 1911 Mhz on a benchmark, that isn't necessarily the highest frequency it can run at. For example, I found a moment in the beachmark that I know for a fact it hits the power limit at 1911 core speed while just using GPU boost. So I went back into afterburner and set a off set of 109+ Mhz to the core and kept the power limit at 120% and reran the benchmark. Now I was running at 1989-2000 Mhz stable with essentially the same amount of power (still hitting my power limit but now I'm running a higher clock speed). And that wasn't the highest OC I could achieve, just the easiest and quickest.

TL : DR
It seems that while my card is hitting it's power limit fairly often, it isn't necessarily using that power efficiently. So while my card appears to be hitting a power limit wall, in reality I can achieve much higher clocks with the same amount of power by doing it manually.
