GPU-Z Memory leak when left opened for days

When I run Gpu-z (latest version) for over a few days with the "background temperature logging" turned on. it seems the memory usage of gpu-z grows.. does anyone experience this?
 
ah yes, the monitoring stores all the recorded data. let me see if i can add something where it periodically removes old measurements
 
Any update on this? Or is this a different memory leak?

This is after 10.5 days running.

to be fair though, who runs gpuz for 10.5 days
 
Still, 1.5 GB is a *lot* of data ... sounds like more than history accumulation.

That's about 1.5KB/second.

Seriously;Who runs GPU-z for more than a gaming session?
or a benchmark?
This is from me to you:
Click that when you go to sleep and/or don't need your comp to be on and this problem will go away.Like magic, even.
10.5 days? I couldn't leave the same computer hooked up that long. :oops:

good info none the less keep it up.
 
I checked the code, each sensor stores 60*60*6 samples at maximum, so 6 hours

Have you seen memory usage grow significantly over the last days too, or only on the first day?
 
i sense a new forum game :D

People who hibernate/sleep their computers at night instead of shutting down? People who have multiple monitors and keep their monitoring apps open on the secondary monitor?

My PC's uptime is currently over a month and I'm pretty sure GPU-Z has been running most of that time. I'll check the memory usage tonight, but as far as I know I've never had this problem.
 
4 hours ago, started a 2nd process to see memory usage change over time from the begining.

4 hours later, original process over 11 days running:

My GPU-Z 0.8.5 has been running since 2015-09-18 and is currently using under 40MB. Looks like you've found a leak somewhere, somehow.
 
Some sort of "aftermarket" Windows theming program? Anti-virus? Some other OS add-on possibly?
 
Private working set at
1,692,280KB for original process
127,488KB for process running 18 hours

Just started a third and turned off "continue refreshing the screen while GPU-Z is in the background" - Will see if that has any effect... seems to have slowed the rate of increase, but not completely stopped it. might have to try a minimized process instead

So far all these other processes have remained on screen and subject to paint messages.

Thanks for your testing!
 
Seems like the third one with continue refreshing, is increasing memory footprint but at a much slower pace, here's the current snapshot.

Haven't looked at the PE header yet, is this compiled with large address aware? Wondering if I should expect a crash at 2GB usage or 3GB.

Definitely stopped working at 2GB rather than 3GB, and quite a bit less memory usage for continue refreshing off.

Looks like I'll also have to be watching MSI afterburner for crashing soon too, as that's at 1.5GB in 26+ days


Tried to change view from 980 ti to on-die intel graphics to see if blank values would recover.. instead got a crash:

I've been having this memory leak as well, but it only began after I updated my drivers. I'd been using 0.8.5. before then with no leak. Got a GTX 660 with driver version 355.82 installed.
 
I did some investigating, and it seems to be caused by a memory leak in NVIDIA's drivers, not GPU-Z.

I did find some small HDC and HBITMAP leaks which will be fixed in next release, so it wasn't for nothing :)
 
Fancy the video driver still having memory leaks after all these revisions lol.
