GTX 1080 complete memory testing

post #1 of 8
Thread Starter 
I have time to sit at my computer and click a button every couple minutes while studying so I am doing some benching and wanted to share the results. I will update this later with Tomb Raider 2013.

Specs for all tests-
R5 1600x @4.0GHz
16gb EVGA 3000MHz CL15-16-16-35
(the rest is in the sig)
GTX 1080 Gigabyte windforce using MSI Afterburner
+10% core voltage
100% power limit
83C temp limit
+140 core clock
Started benchmark with GPU at 60C, it remains below 70C
Other programs open during tests are Microsoft Excel, MSI Afterburner, one folder

SO the only thing changed between tests is the +memory clock. Never an artifact or crash in any test.

Here are my Superposition 1080p Extreme (red) and Valley 1080p Extreme (blue) results. The X axis is memory offset and the Y axis is score.



For Superposition I dialed it in in the below graph



EDIT 1:
Tomb Raider 2013 at Ultimate 1440p. Looks like +450 was second best and not trailing by much behind +800.



EDIT 2:
Heaven had quite boring and predictable results




Let me know how your card compares. It looks like for me +450 is ideal.

Thoughts?

I've found the same thing. Somewhere between 550 and 600 offset seems to perform the best. Anything higher than that can be off an on. One time it'll run "ok", the next time it'll perform amazingly, and the next very poorly. It's in the error corrections. That's why performance can be wildly sporadic, and even to the point that once you get high enough, even with the looser timings, you may hit some performance peaks.

All in all, you're not doing yourself any favors....yeah, it might throw you a bone and give you a few fps in a benchmark once in a while, but....meh. I'd never take a score from a benchmark that was flaking out like that.

To check that testing was consistent to justify doing each test only once I tested multiple runs with the same offset but at lower memory speeds like +100. Are you saying I should do this at higher speeds like +800 to see if multiple runs at the same speed yield a similar score?

Sorry to hijack your thread but how is the 4K high/non-ultra gaming of this card? Can you run say 1080p vs. 4K med/high settings or comparsions? I have a RX 480 and been thinking of upgrading to 1080 gtx, but if I don't get near double the FPS in 4K I might just wait for the 1180.

I do not have a 4k screen to test that with. Not sure if I can run 4k benches with a 1440p screen. I can however speak to my experience. At 1440p the 1080 was awesome at games even with my old FX8370. Paired with a good CPU you can run any game at max or near maximum settings at 1440p 60fps.

I am sure there are dozens of reviews about how it performs at 4k. At medium settings It could probably do 4k.

nice thread, but btw you can test 4K with DSR features (although the scale is not an ideal on the 1440p screen). Just put it up to x1.78 (or 1.75) via DSR on NVIDIA Control Panel setup). because put it up to 4x will give you 5K resolution which is too much for GTX 1080.
