morpheon Posted August 20, 2016 Share Posted August 20, 2016 Hi, For some reason the video ram reporting for all stats (usage, free, total) is reporting in the thousands shortly after reboot (currently I have 4184026mb of ram at 51075% usage ;P ) This just starting happening with the new drivers from nvidia so far as I can tell - thats the only thing thats changed. I have run this in both SLI and single card modes, removed and readded the sensor items etc... Any other thoughts? Quote Link to comment Share on other sites More sharing options...
Fiery Posted August 23, 2016 Share Posted August 23, 2016 Please let us know exactly which ForceWare release do you have installed, and what Windows do you have running on your computer. Thanks, Fiery Quote Link to comment Share on other sites More sharing options...
morpheon Posted August 23, 2016 Author Share Posted August 23, 2016 Version 372.54 - WHQL Release Date Mon Aug 15, 2016 Operating System Windows 10 64-bit Windows 10 Anniversary Update 64-bit Thanks Fiery! upon rebooting things are correct for a while but after closing a memory intensive program this seems to occur. I'll continue to test. Using the latest beta of Aida64 as well. Quote Link to comment Share on other sites More sharing options...

morpheon Posted August 24, 2016 Author Share Posted August 24, 2016 Actually had nothing to do with the programs. This happens after reboot after a few minutes but the timing is not consistent so its hard to figure out if something it triggering it. I went back to the last stable Adia release and same issue. I might try rolling back nvidia drivers just to see... Quote Link to comment Share on other sites More sharing options...
morpheon Posted August 26, 2016 Author Share Posted August 26, 2016 UPDATE!!!! It happens when I close Chrome!!!!! Not sure why but this happens with both beta and stable Chrome releases. I dont have a lot of extensions installed but I will get those a shot. Any other thoughts? Quote Link to comment Share on other sites More sharing options...
morpheon Posted August 26, 2016 Author Share Posted August 26, 2016 UPDATE 2! https://www.grammarly.com/ This was the extension - close chrome and boom VRAM went crazy - removed this grammarly extension and all is well. Hopefully this info is helpful to you or someone in the future. Quote Link to comment Share on other sites More sharing options...
morpheon Posted August 26, 2016 Author Share Posted August 26, 2016 UPDATE III Sadly I spoke too soon - it was not that extension but Closing Chrome definitely triggering the issue, Quote Link to comment Share on other sites More sharing options...
Fiery Posted September 1, 2016 Share Posted September 1, 2016 We've tried to replicate the issue using ForceWare 372.54, but it didn't come up on our test systems. Let me know if the issue still comes up with the latest ForceWare WHQL release of 372.70. Thanks, Fiery Quote Link to comment Share on other sites More sharing options...
morpheon Posted September 2, 2016 Author Share Posted September 2, 2016 HI Fiery, After a LOT of testing I can say that it absolutely has to do with SLI. If enabled (even on 372.70) within a few mintues the readings will shoot up - always to something like 4184026mb of ram at 51075% ish. If I disable SLI the reading returns to normal immediately. Play a game, chrome - readings stay normal. I tested this for over 48 hours with no reading issues. Enable SLI and within a few minutes of gaming or chrome use the reading will shoot up again. I am lucky to have 2 GTX 1080s. For a long time this was working normally but over the past month or so it changed. I should also mention I am a windows insider on the fast ring (would go back to anniversary but its too late now without a fresh install) Perhaps that has something to do with it but I can promise you now SLI is at least triggering the issue. Thanks for taking a look! Quote Link to comment Share on other sites More sharing options...
morpheon Posted September 8, 2016 Author Share Posted September 8, 2016 Any thoughts Fiery ? Should I just reformat and install win 10 ann stable? are there any logs that might be helpful that I can send. I can easily trigger the bug.

Fiery Posted September 8, 2016 Share Posted September 8, 2016 Can you please create and submit a nVIDIA GPU Registers dump before and after the anomaly occurs? You can create such dumps by right-clicking on the bottom status bar of AIDA64 main window --> Video Debug --> nVIDIA GPU Registers. Copy-paste the full results into this topic, or attach the results as a TXT file to your post. You may need to enable status bar in AIDA64 / main menu / View first. Thanks, Fiery Quote Link to comment Share on other sites More sharing options...
morpheon Posted September 9, 2016 Author Share Posted September 9, 2016 Thanks! Here are four dumps 1 Sli Disabled - Correct Ram Readings 2 Sli Enabled - Correct Ram Readings 3 Sli Enabled - Incorrect Ram Readings (bug) 4 Sli Disabled - Correct Ram Readings return https://www.dropbox.com/s/lofzc4vvytbtk6n/nVIDIA%20GPU%20Registers.zip?dl=0 Quote Link to comment Share on other sites More sharing options...
Fiery Posted September 9, 2016 Share Posted September 9, 2016 Thank you! That looks like a ForceWare driver bug. Via the standard nVIDIA video driver API (called NVAPI) ForceWare reports the following values when things go south: Total / Free Video Memory = 8388608 KB / 9376044 KB Obviously "free" should never exceed "total" Quote Link to comment Share on other sites More sharing options...
morpheon Posted September 9, 2016 Author Share Posted September 9, 2016 Ok! Well I will roll back to a June driver and see if that helps. But ultimately we need nvidia to fix this ? I know some folks on the Geforce team I can reachout to if so... Quote Link to comment Share on other sites More sharing options...
Fiery Posted September 9, 2016 Share Posted September 9, 2016 As long as free exceeds total, it's nothing we can do about it We need the video driver to report memory usage properly. Quote Link to comment Share on other sites More sharing options...
morpheon Posted November 17, 2016 Author Share Posted November 17, 2016 HI! Just FYI this was finally fixed in forceware 375.86 - it was known for SLI configs only. Quote Link to comment Share on other sites More sharing options...
Fiery Posted November 18, 2016 Share Posted November 18, 2016 Thank you for letting us know about the resolution Quote Link to comment Share on other sites More sharing options...
