Hi,

recently my gpu has not been working properly i'm getting so much stutter while playing and when i run GPU-Z this is what i see on my sensor tab

http://gpuz.techpowerup.com/18/01/27/v8m.png

When i hover the mouse on the Prefcap tab it shows me ( Vrel )

this is my PC spec:
Intel core i7 4790
Gigabyte Z97X-UD5H
16GBytes Dual RAM
Nividia Geforce GTX 1080
Gigabyte GZ-EMS65A-C5 650W PSU

for me i feel like everything is right but still my gpu feels like it's missing 1 leg

 


Is yours in a different language? I see idle. That's a valid reason to throttle down the card.
 


Do you mean the GPU-Z ? No i'm using English on my PC nothing else, i just took the screenshot while my mouse was not on the tap and it was taken after i stopped playing.
 


What is vrel? I see through the little Prefcap typo but vrel is stumping me.

Hi. This happens to me too for whatever reason. vRel in the PerfCap tab means your performance cap is due to voltage reliability. A lot of people seem to be having this issue lately especially when using Anti-Aliasing on nVidia cards. A lot of people say it's due to latest nVidia drivers and claim to have fixed it by installing older versions of the driver (was no luck to me). Basically what it means is that the card can't draw the required voltage and it'll fail-safe by crashing. This can be caused by literally anything (literally literally). Potential cause:
1) Driver issues - drivers instruct the card wrongly on voltage draws/voltage caps whem usim Anti-Aliasing
2) vBIOS issues - voltage fail-safe cap on your graphic card's vbios is set to too low
4) Motherboard - your motherboard doesn't distribute the voltage properly
5) Power supply unit - your PSU is not throwing enough power for your board
6) cabling issues - PSU throws enough power but it doesn't get through cables as it should (This is extremely dangerous as it can mean your cables are broken/too thin, etc so they can literally start a fire. It is also very unlikely)
7) Faulty power socket on your wall - your wall power socked doesn't throw enough power at your machine - easily fixed by changing sockets
8) Faulty/not powerful enough extension leads (if you're using any).

None of the driver/vBIOS updates worked for me so I had to downclock my GPU to use less power. I down clocked the core speed by -50MHz and Memory speed by -200MHz. Clocks are now running at 5599 MHz for memory and 1911MHz for CPU. Hope that helps. There was no communication from nVidia in regards to acknowledging a driver issue, neither something on a vBIOS issue....

You can try and fix your problem by doing what I did, but please do some basic troubleshooting first: change the wall power socked that you use, stop using extension leads, if you have the means swap your power supply, etc. Use Firestorm if you have a ZOTAC card or MSI Afterburner for pretty much anything else

Also it'd be nice to come back here and let us know what worked for you
