since turning off superfetch (until l get more ram) my memory usage has gone way way down, especially after watching video files, however l need to watch more to get a definitive result.. will keep peeps posted (wish l didnt have to turn if off tho but its working at the moment so l shall keep it under observation to see how things go)

tho one thing l will say, when l woke up ny systems idle usage was around 900meg, and after messing around with firefox for a few hours and messing around with some japanese games lm using no more than 1.9gig of my 3gig of memory

I switched from avira antivir to MSE last week and it fixed my leak.

as previously mentioned, the tweaks l made by disabling superfetch have worked out well, when idling and not doing anything l idle at around 900meg and l notice no slowdown, the only things taking up the most ram are Bitdefender, Vuze, and Firefox before l had less than 900meg left to spare while running after watching video files but now l have a spare 2gb to play with out of 3 (that is until l can afford to splash out on 8gb sticks)

Randomly happened again. Loading a 700mb .mkv file. The file played eventually, but not until somehow consuming all 4gb like before.

Please repeat test case with Win 7 64 RAM filling up. Memory leak outside windows?

And consider Win 7 64 RAM filling up. Memory leak outside windows?

It's either an errant codec or zplayer. I strongly suggest using Divx if only for it's Windows 7 Media Foundation native Matroska splitter which can utilize the trouble-free h.264 codec that comes with Windows. How about dumping CoreAVC for the short term and retesting?

Well I'd really appreciate to hear if anyone has learned anything about this memory rubbish. I haven't posted in months, but mostly because I had no reason to expect any more success at fixing it as with all the other issues that still plague windows after decades of "upgrades".

Like I said before, it has nothing to do with specific codecs or media players. I've reinstalled (win7 64 pro) about 3-4 times since the summer, and never even installed core avc, or zoomplayer. I've been using the basic vlc which has been improved enough to handle 1080p perfectly now.

However, the RAM still is constantly at high usage levels, and now more than ever, everything from Notepad to Firefox suffers intermittent bouts of (not responding) if I dare to do so much as "click" and type more than three letters in a row. How dare I!

Notes:
Just ran sfc /scannow and got nothing. I'm running 4GB of DDR3, 32GB ssd with 2GB of pagefile, with 10GB of pagefile on a 2TB partition at the beginning of the drive. All drives are recent SATA or SATA2 models, all have been chkdsk'd and defrag/optimised within the last month, a quick bench shows all are running at avg to normal read/write speeds (have accidentally jumped into PIO mode before). Windows is up to date, motherboard has drivers from ASUS website and GPU the latest ATi driver.
Edit: Superfetch was still Automatic by default, though the install drive is an OCZ SSD. Rebooting with it off...

You should consider using perfmon, or using Process Explorer and VMMap to figure out exactly what type of resource is being used. Worst case scenario, getting a complete memory dump during times of high memory pressure would be another way. That would be more painful, but would work.

I have been using perfmon, as per my screenshots.

As far as VMMap, I can see that every process (about 60-70) has a great deal more "committed" than "in use" or "working set", the total of these "committed" quantities could equate to what I see in the performance tab of taskman, but there's no single offender. Firefox gets up to 300MB or so with average use (200MB working), but everything else is below that level (even vlc playing 15mbps 1080p video) except for a game.

I did swap the memory out for a 4x2GB set, which has temporarily alleviated the "crunch" of running out of memory with a 3D game running, but still does nothing to explain why 7 likes to use 2000MB for system processes, keep 1800MB in standby, and then yell at me when I try to run something requiring 30-40% of system memory...

It should be giving reserved memory back to you, but actually committing memory at that clip seems quite odd. It might be worth getting a complete memory dump of the system once it gets bogged down, honestly, so we can take the memory manager apart for you.

This is the first dump I've recorded. Unfortunately I couldn't get the memory to fill up (I am still running the 8GB set), but the system was "not responding" massively, so I forced a crash dump (ctrl+scroll lock).

Code:

If there's a better host for distributing this size of file (100MB+) let me know please. Thank you!
