Overclocked 1080

[NiamhNyx]

I have seen around that most people usually get around 100-150mhz on the core and 400-500mhz on the memory.

 

I have gotten my core clock to +110 (2063mhz).

I have been using Heaven and MSI Kombustor to see if anything if weird.

Kombustor shows that I get artifacts once I go to +115. Is this the limit for me on the core clock or is it only once the artifacts become noticeable?

 

 

My ram on the other hand is at +1000 (6003mhz*2). I do not see any frame drops, artifacts, or any graphical issues.

Are there any down sides I need to know of with highly clocked ram?

 

EDIT: I have added two images to somewhat explain what I am talking about. (I am not using heavy benchmarks right now as my 1080 is blocking all airflow to my cpu, waiting for my new case to arrive.)

Increase voltage. What card is it? Wonder why msi locks the power at 104%.

2063's a pretty good result. You're not likely to get much more than that. You'd be doing a lot of work for another 2% performance. If you want to you can mess with voltages, fan curve, and stuff like that, but if it were me I'd just take the 2063 to the bank.

I messed with it a bit more and was able to get it to 2101mhz. Cant get it any higher even with voltage increases. If i go 10mhz more I get some issues in Valley bench.

 

EDIT: also the memory clock at max seems to have no negative effect on performance. I went all the way from +1000 to +200 and back again to make sure. Was reading online and a lot of people said it has huge negative impacts on performance if its to high.

 

Would my cpu have any major effect in the benchmark tests? I have it locked at 3.2ghz (i7-8700) until i get a new case.

Everything would effect benchmarks but not oc stability on the gpu. Unless temps were really that bad.

My 1080 stays under 65c, because it takes ALL the air flow. My cpu, when I turn on the boost hits about 93c with the 1080 in the case, 68c when its not in the case.

Yea the gpu temps are reported but not the rest of the board. Case needs better fans or a better case. So these are real world temps?

Yea, real world temps there.

I have already ordered a new case. The one I currently has, first off has its intake fan blocked by the HDD bay. It wouldn't be to bad if the HDD bay was not a solid wall, but you know how it is with a cheap case. Then my 1080 legitimately touches the side panel window and the very front of the case. so the little air flow to begin with is sealed below my gpu >.<

Not on Valley or Heaven. Those are insanely GPU limited benchmarks. Even my old 3570k wasn't bottlenecking my 1080. 

 

Honestly though, my 4.4ghz 8700 has never been a bottleneck for my 1080 at 1440p 144hz from anything I've noticed.
