Strange 1080Ti Issue

ChrisUK1983 · 3 Sep 2018 at 11:48

Picked up a brand new ECGA 1080Ti SC Black Edition from OC at the start of last week and have been running into an issue ever since.
System specs (all brand new):

Ryzen 2700x
16bg Team Group Ddr4 3200
Asus Strix Gaming F X470
Samsung 970 EVO 500gb NVME

Basically any game I play which utilises 100% GPU load will freeze the display (audio still continues) forcing me to close via task manager. Ive logged numerous games with GPU-Z and the common denominator is the game will hang as soon as the GPU hits 100%.

Event Viewer then either shows an error related to nvlddlmk and/or "application was blocked from accessing the graphics hardware".

Ive tried numerous NVIDIA drivers using DDU, 3 fresh installs of Win 10, Motherboard BIOS updates none of which has worked.

The only workaround that seems stable at the minute is to down clock the GPU core -25mhz in MSI Afterburner.

Anyone got any ideas before I RMA the card?

Sounds like an issue with your 1080Ti, if it is not holding its advertised clocks and boost.
The fact you are down clocking it suggests an issue with the GPU.
RMA it.

Thats my suspicion too. Driver conflict was my first thought until I "cured" it by down clocking.
RMA has been issued, so hopefully have it sorted shortly.

In the meantime, what happens when you increase the GPU core voltage?

Exactly what I would have asked. What PSU is powering it?

Do you mean at stock clocks or at its current -25mhz state?

At stock, adjusting the power limit/core voltage has no effect. The card still crashes to desktop at 100% load. (Havent touched the voltages/power limit with the downclock).
The PSU is a Corsair TX750. PSU is the only item that isnt new (approaching 2 years old now). But was previously powering my heavily overclocked 1700x/1080Ti Auros setup a couple of months ago with no issues at all.

Just had a play around with Afterburner.
Set the core voltage to 100% and the power limit to 135% with the -25mhz downclock.

Loaded up Two Point Hospital which was always a guaranteed crash at stock within the first few minutes. Solid as a rock.

Looking at my log file from GPU-Z, the previous crashes at 100% load the core voltage was 1.0310v.
The log just now peaked at 99% usage with a core voltage of 1.0750v with no crash. I reckon that rules out a power issue?
I think Ive just been very unlucky in the silicone lottery and got a card that doesnt like stock settings.

Update on this in case anyone has a similar issue in future.

Card eventually made its way back to Overclockers today despite DPDs best attempts to lose it

Tested, found to be faulty and a replacement on its way.

Excellent customer service as usual.
