Maximium Memory Usage, How!

By slater_aid ·
I have 512 MB on a workstation system, and I want to make the machine use the Maximum memory it can. I have many disk/memory intensive apps that should be draining the cache, so I would like any suggestions on clearing this up in Win 2K Pro. I just don't feel I am getting the best performance out of these systems. I still get the occasional prog lock/NR, but the resources available are barely tapped. Any suggestions?

Maximium Memory Usage, How!

If you are not running out of resources, there has to be a different cause for the lock-ups and crashes.

Low memory usage likely means that W2K's built in memory management tools are doing a good job.

You really don't want Windows to use more memory than it needs.

I know this may sound like a broken record, but the first thing to check for any Windows lock-up problem is that you have the latest system board and video drivers.

After that, you need to try and determine what is happening just before the system locks up.

1. Most likely lock up/NR is not cause by your apps competing for the same resource, and not by your RAM either; especially when you said that the amount of memory used is low. Use W2K Performance Monitor to monitor your system activties, such as your apps' CPU and memory usage, socket, threads, etc. I am curious: How do you know that your apps suppose to drain your cache?

2. You need to give more relevant information to make informed evaluation. (how much CPU was used? What's the processor queue length? What's the % Committed Bytes in Use? etc. ) Did you find out how each app runs, how each app uses memory and disk resouces. How are your apps set up. Are I/Os spreaded across multiple drives (I presume you already know that you need to have multiple drives to spread out your I/Os) or they are waiting for disk access? Based on the limited amount of info you gave, if I have to guess, your apps along with the OS are competing for disk access and this may explain why the memory usage is low (assuming that the apps are suppose to use more memory when run at full speed . Use PerfMon to track how your disk or disks are being used and more likely you'll find your hot spot here .if they are hardware-based.

3. Check the software requirement for each apps and ensure your system met the minimum requirement specified. Also, it's possible that one or more of your apps may require a specific driver version and may not work correctly even with newer version (not backward compatible). Use DRWATSON to monitor your apps and catch problems when they occur. Use System Information to find out version information to ensure minimum requirements are met.

If you want your app to se the max memory then you need to check the doc for each app for user-settable setting. This is the only way to do what you want.

As far as the OS is concerned, the OS always give the apps what they ask for unless the apps asked for the amount of memory larger than the available virual memory the system has in which case the apps fail and may crash.

Thanks for the info. I got what I needed. Just a few details overlooked.
