Question Issues with testing EVGA GTX 1080 SC ACX 3.0

[JWMiddleton]

I recently (ASSUMED) I bought an EVGA GTX 1080 SC ACX 3.0 from a TeAm member. I was previously running a GTX 1660 Super. I simply took out 1660 and put in the 1080. It ran fine and games worked. When I would wake up the monitor after it went to sleep, the screen would come on, then flash. No issues until the next sleep session.

I wanted to see the improvement with the 1080, so I ran a few benchmarks. Heaven and Valley did great, but Userbenchmark and 3DMark Time Spy (DX 12) gave me errors as neither of them would give me a score. Time Spy would not complete a run and said "an error has occurred." Userbenchmark indicated an issue with the GPU, but didn't say what it was. I tried 3D Mark Fire Strike (DX 11) and it ran fine.

In talking with the seller I used DDU to uninstall the driver and reinstalled latest one. The screen no longer flashed, but same issue with Userbenchmark and Time Spy. It is not a big deal that they don't work, but I would like to see if I can get it resolved.

I wondered if what I'm seeing in GPU-Z has anything to do with it. The info displayed looks correct, as you can see in the attachment, and when I click Lookup, it brings up a later version of the card with Pascal a 104-410-A1 chip vs the older 104-400-A1 version. So, Lookup shows an EVGA GTX 1080 SC2 w/ iCX Cooler 11Gbps. Turns out that I ASSUMED incorrectly.

System in Sig is up to date. I do not have any OC utilities installed. So, any ideas?

Actually. My card's memory is OC'd bigly. About 12.5%. That might account for the closing of the gap between our cards. Let me run it again without the OC.

 

[solidsnake1298]

Ok. With no OC and the power target at default 100%, the gap between mine and yours is about where it should be. Its still weird you can't get 3dMark to work properly. Is your CPU or memory OC'd? But that wouldn't account for the flashing and green lines you described.

 

[PClark99]

Any chance you have a second machine to test it in and see if the situation replicates.

I'd wondered if your card was OC'ed a bit to make the difference. I did find a place with scores for Valley, but it is insane with SLI systems posting score. I realized that my original run of Valley was with older drivers, I re-ran it this morning, after a reboot, and got a little better results. We are at your 93.3 to my 115.

My CPU is stock, mem is set using XMP profile. The lines that flashed across the screen were not green, rather they were thin gray or black and very fast. Just enough to notice that something was wrong.

From what I've learned, I'm thinking that EVGA made a variant of their 1080 card for Best Buy that has the iCX cooler, but not the temp sensors and dual fan control.

No, the other machine is a Dell OptiPlex 3020 MT with a 290 watt PSU. I've got it setup for when the grandkids visit.

So, since you are the original owner, I would assume that you don't know of any mods that were made? Did you ever run the of the 3DMark suite?

I am the seller of the GTX 1080 SC card. I purchased the card from another board member in October of 2019, and it has been running flawlessly in my son's i7-8700K system since then. He played Apex Legends, Valorant, and Overwatch on it with no problems at all. The only benchmark I ever ran on it was Unigine Heaven (DX11) when I first installed it in his system and again when I moved it to my test system prior to selling it. On my open test bench (pictured below), the temperature of the card did not exceed 68C when running Heaven for 20 minutes.



The model number of this GPU is 08G-P4-6283-KB (EVGA Product Page), and it is an EVGA GTX 1080 SC Gaming model. EVGA has long used the -KB designation on their GPU model numbers to denote those sold at Best Buy (which is where this was purchased by the original owner). The part number on the EVGA page actually says 08-P4-6283-KR even though the title shows 08-P4-6283-KB. The cooler says ICX on it instead of ACX 3.0. I suspect this is similar to their GTX 1080 Ti SC Black GPU that has ICX on the cooler--even though it doesn't actually have the 9 temperature sensors that their regular silver-colored GTX 1080 Ti SC2 card has. By the way, I don't think an regular GTX 1080 has a SC2 model--only the GTX 1080 Ti.

Like we've discussed in PMs, the Time Spy benchmark tests DirectX 12 performance. So, it would be beneficial to run something that you know is using DirectX 12 (Rise of the Tomb Raider can use it) to see if there is anything wrong with DirectX 12 on your system since you don't seem to have any trouble running DirectX 11 games and benchmarks. I can't say for sure that the card has no problem with DirectX 12 since all of the games my son ran used DirectX 11--as did Unigine Heaven.

I have a Gigabyte GTX 1080 Mini in a home theater PC, and I ran Time Spy (DirectX 12) on it this morning with no problems. The GTX 1080 Mini has slightly lower frequencies (1607 Base/1733 Boost) than the EVGA GTX 1080 SC (1708 Base/1847 Boost), plus it runs pretty hot at 76-78C since it's in a 6.7 liter case. Here is my results from Unigine Valley. Yours look to be what I would expect from the better clocked EVGA model versus my Gigabyte model (115 fps vs 111 fps).

I am the seller of the GTX 1080 SC card.

Thanks for posting Paul and for the explaination! Someone on another forum said that 3D Mark has another DX 12 benchmark called Night shade. I just ran it and it ran fine. I've attached the results.



What still bothers me is that even the slightest OC with Precision X1 results in lower results. I am going to install the older version from the disc you sent and see if that makes a difference.

Saw your question.
So this was original!y my card from best buy.

I never did any mods flashes or anything this card was only gamed on.

Never mined either

 

[Hail The Brain Slug]

Nevermind. The Best Buy product page clearly states 11Gb/s memory.

I know it's a big pain in the ass, but do you have a spare drive you can throw a fresh windows install on and install the latest Nvidia driver?

Barring that, can you install the latest Nvidia driver with the "factory reset" option checked?

I just had someone I helped the other day with a card that was crashing in time spy that was resolved with a factory reset driver install.

 

[JWMiddleton]

Barring that, can you install the latest Nvidia driver with the "factory reset" option checked?

I will give that a shot. Thanks!

UPDATE: I deleted EVGA Precision X1 and installed MSI Afterburner and Kombuster. I did a +50 core increase and +30 memory boost and ran Valley with an .9 fps increase. I tried to get the previous version of Precision off the CD, but it simply takes me to the EVGA website where the only thing available is X1.

I will removed all OC stuff and reinstall the driver with factory reset.

I wouldn't be overclocking when trying to troubleshoot. I've never done any overclocking on the card--only ran stock.

You missed the point I was trying to make. This card is suppose to be an overclocker, the software is on the CD that is in the box, or a link to download it. Thus, it concerned me that overclocking using EVGA software was hurting performance rather than improving it. So, using MSI Afterburner was troubleshooting that issue. And I was successful! So, it seems that the new version of EVGA's OC utility doesn't play well with this older card. Now that I know that the card will OC, I removed all OC'ing utilities and reset card back to factory settings.
