Win 7 pro 32 bit memory usage

early 2006 macpro 1,1. installed win 7 pro 32bit on separate wd black caviar640gb. win says it can see my 5gb memory installed, but usable is only 1.99gb. how can i get it to use more of my memory? won't win 32 bit use 4gb??
thanks

32 bit Windows OS can only address 3GB RAM nominally. The actual address space that is addressable depends on system architecture but could range from 2 to 3.75 GB. Even theoretically 32 bit system can only address 2^32 addresses. Then remove reserved/shared address space from that limit.
If you want to address 4GB or more RAM you will need the 64 bit version of Windows.
EDIT
The hatter provided the answer as I was typing. Once again I suffer from having to type using the "hunt and peck method". I must learn to type faster

Photoshop CC 64 bit memory usage

I have just built a Windows 7 64 bit PC (Windows 7 Professional) with 16Gb of Ram. However the 64 bit version of Photoshop CC only sees 4gb (or there abouts). This is the same as the 32 bit version.

After a deal more of fiddling and scratching various bits of the anatomy, I have reinstalled Photoshop. The 64 bit version now sees just under 16GB, which I would suggest is now correct.

Is anyone else seeing memory leak/resource hogging in 3.6.15 -process fails to terminate after shutting it down, 170M memory usage, win xp pro

Running xp pro (up to date on updates)
if I leave firefox open for a while, then shut it down and later start it up I am told it is already running, looking at processes shows the process is indeed still showing with over 170M of memory usage (excessive).
Nothing odd was open, no adobe etc (adobe X is a whole 'nother issue )

I have the same problem (Firefox got up to a staggering 1.3GB of RAM!).
Well, I've managed to "fix" it (until it is fixed in Firefox itself) by a RAM optimizer.
I use Smart RAM, which is a small but great tool from the Utilities section in [http://www.iobit.com/advancedsystemcareper.html Advanced SystemCare], which got Firefox down to only 20MB of RAM.

Perfomance/memory usage issues running LR 3.3 on 32 bit Win XP

I'm using LR 3.x for some time now, at the moment my version is LR 3.3. My machine is set up with a 3.6 GHz core 2 duo cpu, 4 GB of RAM and four samsung spinpoint hdd. LR 3.3 runs on Windows XP SP3 32 bit OS, usable memory is 3,25 GB. At HDD 2 LR is installed, at HDD 3 library is located, at HDD 4 LR cache (20 GB) is located. I use one "big" library with around 20.000 raw images. I use 1:1 preview and deactivated deleting preview.
I noticed that LR is working slow after some time of working on raw images. Tools are lagging, rendering takes very long and sometimes I get the error message that not enough virtual memory is available anymore. Also in task manager I noticed a continuos increase of memory usage, starting around 800 MB, ending up - I can't work anymore - around 3,00 GB. Memory usage never lowers.
Do you have any information how to solve this perfomance/memory issues? Thanks and best regards from Germany.

There is a large thread for this.

JDK1.4.0.2 Memory usage on Win 2K.

By default Win2K does not yield much of the requested Java heap space in physical memory. It appears to give a small fraction to physical memory and the rest is kept in virtual memory.
I've tuned the platform to have only absolutely necessary system applications running, minimizing other apps memory usage, it always appears that the heap could be allocated in physical memory, but it is just not done by the OS.
My server has 2 Gb of ram, and my java app requests 1 Gb of heap space.
I see quite a bit of page faults when my app executes under load.
Looking at the memory meter in task manager, their appears to be easily more than 1Gb of free ram available, yet my process continues to page fault.
Is there a way to get the JVM to lock/retain more physical memory and reduce the need to use virtual memory so much? It really does not appear to be a memory contention issue with other apps? I'm using jvm 1.4.0.02 on a dual cpu del 1.5 Ghx with 2gb Ram.
Regards.

I am having same problem, did you get a solution yet.

I want to install windows7 on my 27in iMAC. I have an OEM version of Win7 which is win pro 7, 64 bit english. I will use boot camp to partion the hard drive for a win7 install. Can I use this version for the installation ??

My iMAC is a 2011 3.4 GHz intel i7 based with a 27in display. A year ago, I bought a Microsoft win pro 7 64-bit english OEM OS to install over a newly assembled AMD PC. I never installed it. Now, I want to put it on my iMAC using either Apple Bootcamp or Parallels. The win 7 OEM package has a lot of verbage about using an OEM preinstallation kit (OPK) and that it must be preinstalled on the hard drive. Is it OK to install this win7 version following the Bootcamp instructions.?

Please post in the Boot Camp (not Bootcamp) forum I'm sure someone there can answer your quesiton if no one here is able to.

Sql memory usage increase each time win app runs

Hi,

Hi,
Sql memory usage increases each time when win app runs. Why does it work like this? Is it normal ?
Yes, it is perfectly normal for SQL Server to acquire and hold onto large amounts of memory indefinitely. This memory improves performance by avoiding disk I/O, query plan compilation and costly memory management.
On a dedicated SQL Server you should usually let SQL Server dynamically manage memory. It will release memory if it detects memory pressure. But if you often run other applications on the server than need significant amounts of memory (e.g. IIS,
application services), you may want to set max server memory as suggested.

What's the recommended setting for "Process memory usage" ("process virtual" in UI) for a 64-bit host on a 64-bit OS?

Hi gurus
In resource based throttling, what's the recommended setting for "Process memory usage" ("process virtual" in the resource based throttling tab of the UI) for a 64-bit host
on a 64-bit Windows OS?
According to MS (http://msdn.microsoft.com/en-us/library/ee308808(v=bts.10).aspx):
"By default, the
Process memory usage throttling threshold is set to 25. If this value is exceeded and the BizTalk process memory usage is more than 300 MB, a throttling condition may occur. On a 32-bit
server, you can increase the Process memory usage value to 50. On a 64-bit server, you can increase this value to 100. This allows for more memory consumption by the BizTalk process before throttling
occurs."
Does this mean that 100 is the recommended setting for a 64-bit host on a 64-bit Windows?
Thanks
Michael Brandt Lassen

Hi Michael,
Recommended setting is the default setting which is 25 .dot.
If your situation is abnormal and you see message delivery throttling state to “4” when the following performance counters are high or if you expect any of you integration
process could have impact on following counters, then you can consider the suggestion by Microsoft. Don’t change the default setting.
High process memory
Process memory usage (MB)
Process memory usage threshold (MB)
You can see these counters under “BizTalk:MessageAgent”
You can gauge these performance counter and its maximum values if have done any regression/performance testing in your test servers. If you have seen these counters having
high values and causing throttling, then you can update the Process memory usage.
Or unexpectedly you’re process high throughput messages in production which is causing these counters to go high and cause throttling, then up can update the Process memory
usage.
The above two cases where I know my expected process usage (by doing performance testing) or suddenly my production server processing has gone high due to unexpected business
hike (or any reasons) which caused throttling, then do changes to default throttling setting.
Just changing the default setting without actual reason could have adverse effect where you end up allocating
more processing capacities but the actual message processing message usage ever is low means you end up investing in underutilised resources.

Premiere Pro CC 2014 60GB virtual memory usage

The longer Premiere stays open, the slower it runs and the more memory it uses until the system errors out and makes me close things.
Any ideas? 60GB memory usage seems ridiculous. The total footage size is only 10GB.
Running Premiere Pro CC 2014 and After Effects CC 2014 with dynamic linked files, app nap turned off.

Am having the exact same issue - premiere clogging up my system with excessive memory usage until I am forced to close things. Using most recent premiere update 8.1. Please help adobe! I'm on a deadline!

Logic Pro 8, Kontakt 2.23 & Memory usage

Hello -
*What type of known memory problems might exist between Logic (Logic 8 in particular) and either Kontakt 2.23 or Kontakt Player 2.23??*
*If there are known memory usage issues, what can be done to help/fix the situation??*
My computer set up is listed below. I have not upgraded to Leopard (but did upgrade to Logic Pro 8). By-in-large, Logic Pro 8 works fine. However, I usually "network" the Logic sequencing projects with Muse Research's Receptor (version B) and/or an aging Dell Precision Workstation 650 using Musiclab's MIDIoverLan CP3. This has proven stable for me. For my most recent project, I decided to see how many instrument plug-ins I can utilize within the Logic Pro 8 program (without benefit of this "network" set-up). For this project, I'm using one instance of MusicLab's RealGuitar and 16 instances of +*Kontakt Player version 2.23*+ for a total of 17 instrumental tracks. The instrument libraries used are Garritan's GPO and JABB. With this many individual (not multi) track instances used, the activity monitor is showing high RAM usage. For some of the instruments, I could not use the KS choices (trumpet, trombone) because the extra RAM caused Logic to crash as I mounted more instruments.
I tried adjusting the DFD. Still, there remained high RAM usage and the occasional crash. For some of the crashes, I either got the endless colored spinning wheel or a message basically stating that there was no memory available for the DFD. I am no expert with the advanced workings of Logic and the DFD associated with the Kontakt plug-ins. But I am surprised that using just 17 instrument tracks with this newer Mac Pro computer (with 5 GBs RAM) is causing problems. Sadly, I am not an expert Apple user to be able to tell whether it's the computer or Logic or Kontakt. I suspect, though, its some kind of issue between Kontakt and Logic.
For my audio, I use MOTU's 2408 MK3. For my midi in-put I use M-Audio's Keystation Pro 88. I do not think either one of these devices are causing the apparent memory problems.
By the way. . . before I purchased my newer MacPro computer, I had a similar instrumental set-up using my aging Dell Precision 650 workstation with 2 GB of RAM using Steinberg's SX 3 program. I used the same GPO and JABB sound libraries. It did "challange" the Dell computer (I had to adjust buffer/latency settings to MOTU's 828 MK2 used with the Dell computer), but the computer didn't crash like what I'm experiencing at present.
I don't mind "networking" my computers together in order to use larger instrumental plug-in tracks. But I would think that given the "power" of my newer MacPro I should be able to handle more than 17 GPO & JABB tracks. Yes? No?
*Given my current computer set-up, how many instrumental tracks (using libraries associated with Kontakt or the Kontakt Player) should I get??*
Thank you in advance.
Ted

Sadly, I can chime in with the same basic problem. Namely, that
Kontakt2 seems to leak ram. I've watched the activity monitor show
an increase in ram allocation to logic if i simply LOOK at a kontakt
instance. Just clicking on the instance causes ram to be allocated, and no matter how much I purge samples, I just can't retrieve that ram. Once 2 gigs are sent to logic, crash.
The only solution I've found is to save & restart before it climbs too high. I can then work for an hour or so until the ram overflows again. This is obviously a major bug, and I agree that Logic doesn't appear to be the culprit.
Have either of you tried K3? I wonder if the problem is more under control there? There's no way Kontakt will bother to fix this bug
in v2.23 with v3 on the shelves. The question is, how do we know that v3 fixes it without buying it? I've heard reports that v3 is even
more bloated than v2.
I've recently done a clean install of leopard on a blank drive, and
i'm patiently waiting until NI updates the installers for K2.
Then, i'll have a clean OS, clean newly installed logic 8, and
a cleanly installed K2. Maybe that will help mitigate, if not solve the problem.
I'm almost sure that Kontakt is the source of the problem, but
I've also been told that Intels have serious flaws in their ram
allocation WITH TIGER.
Some people with G5's have reported having access to 3.5 gigs ram.
Intells can only use 2 gigs with any one app. This was thought to be a problem with Tiger and and Intels. So maybe Leopard will expand the RAM wallet, and then we just have to wait for Kontakt to stop spending so much.

WinXP and Vista memory usage with Illustrator CS2 - is Vista winning?

Dear forum.
I have an AI-template file where I insert some very large PNG files into it, modifies the template a bit and then I print the the resulting document in PS-format. The PNG files may be as large as 100 MB (24-bits, approx. 100 mil. pixels in total). It appears that while a Vista-based machine has no problem loading one or even two copies of these huge files into memory, a WinXP-based machine can't even load a single file into memory. Instead, I a dialog box with the message: "Could not read the file because the plug-in could not understand this file". Is it really a faulty plug-in or is it just CS2's way of saying "not enough memory" in a quirky way?
All in all, I would like to hear whether someone has the same experience with Vista, ie. it seems to be better at memory management or better at allocating memory for Illustrator CS2, enabling it to load large PNG files.
The specifications of the WinXP-based machine:
Pentium 4 2.6 GHz
3 GB RAM
Virtual memory 4095 MB in a physically separate drive from the OS disk
All Visual Effects are turned off
Has Illustrator CS2, Adobe Acrobat 7 and Distiller installed (and a few auxilliary programs)
The specifications of the Vista-based machine:
Dell OptiPlex 740SF
AMD x2 5000 (2.6 GHHz)
2 GB RAM (667 MHz, 2 x 1 GB)
250 GB SATA disk
Windows Vista
Adobe Creative Suite 2 Standard + Adobe Creative Suite 3
Thanks!

Hi, everyone
I got a new t440p 20ANA00UHH (8GB RAM, win8 64bits) about one week ago. It works really well, but its memory usage confused me. In Task Manager, the "Performance" option shows memory is 68% (5.4G in use), but "Users" option shows memory usage 66% (1019.5M in use). Is that normal ? I just opened some websites and word files.

AE CC 2014 memory usage continually rises while scrubbing through timeline

When scrubbing through the time line in AE CC 2014 ver 13.0.0.214 memory usage just increases until there is none left and everything starts to lock up. Purging does not return usage to normal.
I'm on Win 7 Pro 64bit(fully updated)

This only seems to have started happening fairly recently.

I too am getting serious memory issues with CC 2014 vs CC 2013 doing the exact same tasks. Not sure why, but the default settings for previews, disk cache, and memory seem to give me the best performance. So basically...
don't enable Disk Cache
leave the GPU texture memory at 1500MB (Previews -> GPU Information)
left "RAM reserved for other applications" at 6 GB (in a 32 GB system)
don't check "Reduce cache size when system is low on memory"
don't check "Render Multiple Frames Simultaneously"
My system...

Acrobat 9 Pro a memory Hog

I have a 175kb 2 page PDF file that I am updating a field in. On save, memory usage soars from about 300MB to well over 2GB causing massive memory swapping on my laptop which is configured with only 1GB of memory. I have trimmed down all necessary processes and this still happens and only when I try saving under Acrobet 9 Pro so I am pointing my finger at it. I am using a trial version of it which I am very happy about since I would not want to purchase this product if I can not save files. I have a Dell Latitude D520 with Intel Core Duo 1.66GHz CPU, 1GB memory running Windows XP Pro.

> I am pointing my finger at it.
I see you aren't looking specifically at memory usage for Acrobat. You
can do this with Task Manager - the Mem Usage column in processes is
virtual memory (not RAM).
I wouldn't be the least bit surprised to see Acrobat doing this, but
still, it's worth checking.

Solaris process memory usage increase but not forever

On Solaris 10 I have a multithreaded process with a strange behaviour. It manages complicated C++ structures (RWTVal or RWPtr). These structures are built from data stored in a database (using Pro*C). Each hour the process looks for new informacion in database, builds new structures on memory and it frees older data. But, each time it repeats this procedure, the process memory usage increases several MB (12/16MB). Process's memory usage starts from 100M until near 1,4G. Just to this point, it seems the process has memory leaks. But the strange behaviour is that after this point, the process stops to continue growing up anymore. When I try to look for memory leaks (using Purify tool) the process doesn't grow up and no significant leaks were showed. Did anyone found a similar behaviour or can explain what could be happening?

Hi, thanks for responding
Ja, i guess thats possible, but to do it all one row by row seems ridiculous, and it'll be so time consuming and sluggish surely. I mean, for a months worth of data (which is realistic) thats 44640 individual queries. If push comes to shove, then I'll have to try that for sure.
You can see by the example that I'm saving it to a text file, in csv format. So it needs to be a string array, a cluster won't be of much help I dont think.
The only other way I can think of is to break it up into more manageable chunks...maybe pull each column separately in a for loop and build up a 2D array like that until the spreadsheet storing.
You only do 1 query, but instead of Fetching All (as the Select does) you'll use the cursor to step through the data.
You can use Format to String or Write Spreadsheet fire with doubles.
You can break it down to get the data day by day instead of a full month at once.

Ps CS6 Memory usage 14GB from 50 meg file???

Hey,
Does this memory usage make sense?
I'm working on a 48 meg file, but my RAM usage was up to 13.9 gigs. I just restarted Ps and opened the file and it's up to 10.7 gigs.
Previously I was always maxing out 10 gigs everyday out of 12 available gigs in the machine also working on small files.( 25-30 meg on average) IT tried playing with things forever and finally just tried ordering more RAM. They ended up putting 28 Gigs in the box. And I'm really not seeing any advantage in Photoshop, other than my system still runs OK outside of Ps while I'm working. (Well Rhino 3D still crashes from being out of memory, even though there was still 6 gigs free??? but that's for another forum) Mostly it just freaks me out how much RAM it's using for such a small file...?
I'm just drawing, no filters, not too many layer masks. I do have maybe 15-20 vector smart objects in the file, and I'm at 147 layers. The issue I was having is Pen lag on the Cintiq when I draw starts getting horrible as the RAM usage gets higher. I had been restarting Photoshop constantly to get it to release RAM. But I haven't the last couple days since they doubled the RAM in the machine. And obviously on restart the file still needed a lot of RAM???
Anyone got any sugestions? I can live with the lag, sucks, but I can still work. I just don't understand why these small files are using so much RAM. Back in the day on 32 bit systems with 4gigs of RAM I would sometimes create posters/covers/magazine spreads that were 1.5- even 4 gigs that would have to be saved as Tiff's because PS didn't support a file that big. This machine runs like that everyday. At home I've been doing some freelance book covers that get up to 450 megs now and then and it still runs better, Cintiq at home draws smoother than this machine that costs 3-4 times more!
It's a win 7 64 bit box, 2 Dual core 2.4 Xeons. two quadro 2000's, now 28GB ram, OS on a 560?GB drive with files on a Terrabyte drive that gets backed up. My hardrives arent rated very high, 5.9, but at least im working local to the machine as the network is slow as heck around here!
Thanks for any suggestions anyone might have!

Your issue is stroke lag drawing. You state nothing about the brush and tool being used. Looking at your hardware and knowing Photoshop is using a lot of ram its most likely swapping a lot ram to scratch disk space. Faster disk may help. Also having two quadro 2000 does not improve Photoshop performance over having just one. Yes Photoshop does not give back RAM it allocate during a session even if you close all the open documents. This may well not be a bad thing. Photoshop is surly managing the RAM space it allocates. Having a lot of ram to work with may well cut down on Photoshop RAM swapping and speed thing up.
Your lag problem may not be a ram problem. Some brushes require GPU support and the size of the rush can easily increase lag. For example if I boot my machine and look at RAM used window 7 64bit professional I see 3.5GB allocated 36.5GB free. If I start CS6 open a new document 11"X 14" 300dpi fill it with a spectrum gradient I see 5GB of ram. In use. If I select the mixer brush tool and a large brush size and make quick brush strokes there is quite a bit of lag and my video card is a quadro 4000 a little faster then your quadro 2000. My swap space is on SSD much faster then spinning disk ratting 7.9 out of 7.9.... and I have dual 6 core xeons.
Some brush type tools like blur, smudge, dodge, burn sharpen require a lot of sequential repetitive processing .. a large tip smudge always seems lag on forever... Its the repetitive nature of the processes that cause the latency not so much the compute power.
