Hmmm, just got me more RAM today, from 64 to 192, now I was told that Windows would need a special utility or something to make more use of the 64 MB above 128 MB than .. just looking at it?

True? False? A rumor? Can someone "enlighten" me?

Windows 98 does not need any "special utility" to use more than 128mb of ram. (Seems that Windows3.1 might have, or even the original '95 version... not exactly sure....)
You might try this though, right click on "My computer", then the Performance Tab, then on the File System button. Set up the computer as a "network server", and "ok" your way out of there. Restart, and away you go. That setting does make a difference in the way that windows will cache the memory available, and if you have more than 64mb ram, then set your system as a "network" server.

Thanks Major, and thanks BigHead, I was reading some posts of that mentioned topic, but wasn't sure about it.

Will try the "network" thingmie!

I think the confusion may lie in the fact that people often say Windows doesn't take advantage of more than 128 megs 'o ram. That's probably true. Why would it need that much anyway?

But that's not to say any other application won't take advantage of the extra RAM. For me, Photoshop in particualr uses lot's of RAM. Using Cacheman I've seen Photoshop using over 200 megs of memory.

So even though Windows may not need the extra memory (Windows uses about 40 megs of RAM on my system) other resource intensive apps will certainly benefit from the extra memory. And the Major is correct. You don't need any special utility in Win98. As long as your machine recognizes 192 megs, it should work fine.

I read some of the above posts, in the mentioned thread. It seems to me that the effect of having 256MB ram vs 128MB ram is significanlty lessened, when one has a very fast cpu, ie:800mhz+, and a 64MB or DDR (double data rate) video card. For those with more mundane systems, 256MB ram and some system optimization is a quick and easy upgrade. Going to put in another 128MB's soon myself, it's down to $85 a stick at the local computer shop....

In addition, it's probably a good idea to make sure your virtual memory swapfile is set to 2.5 times the amount of RAM (it's in the system properties CP, then performance, then the VM button--set both the max and min values to the same--that will "fix" your swapfile at a certain amount and should help performance.

Now lets not let this get 5 pages long ok
the thing is that WINDOWS only uses up to 128 effectively
GAMES will utilize more cause they are GAMES not WINDOWS
it's not like windows fails to recognize the ram it just doesnt utilize it effectively but remember thats WINDOWS, not a GAME
notice that WINDOWS and GAME are two different things that need ram in different ways.
besides numbers dont lie and people notice better performance in their GAMES with more than 128 meg ram.

Hmmm okay, so I shall set the swap file to roughly about 500MB then? Will do that, up until now I let Windows manage it, maybe not that good idea

Thanks for the hints, guys, learned something. And about Windows, as long as the games use the additional RAM, I'm fine!

The two and a half times rule doesn't make sense anymore. Though it was a good rule of thumb back when everyone was using Win95 and 16 MB of RAM was alot.

If you apply the same rule nowadays it means that the people with the most physical RAM would by rule have the largest swapfile, even though they need it less. I do agree that a permanent swap is the way to go. But 500 or 600 MB is probably way too much if you already have 256 MB of RAM. I have 256 and my swap is set to 255. It doesn't matter how large you set it really. The best way to determine the proper size would be to set up Windows system monitor to track the swapfile usage. See how much is used at it's peak when using your computer as you normally would. Then set your swap accordingly.

Hi guys,

Solution from forum pal Mudshark.
He picked it up in an other forum.

Using the msconfig utility, go to the system.ini tab, scroll down to the 386 enh folder, add the line:

ConservativeSwapFileUsage=1

This forces windows to use your physical ram before swapping to your harddrive, since the machine acces' ram faster than it access' your harddrive, you should see a performance boost. He tried this several weeks ago and got a great boost.

Regards

STB

There is also a tweak you can do to force Windows to use all physical memory before doing any swapping to the much slower hard disk. You will need to edit your system.ini.
To do so, go to start>run and type in msconfig. Click on the System.ini tab. Under the heading 386Enh add the following line:

ConservativeSwapFileUsage=1

I have seen some others claim this does not work. However, I have yet to see a reason as to why. Using Cacheman (which shows virtual memory usage, among other things), I find my 256 MB (physical), 255 MB (virtual) system uses about 40 MB of swap even if physical RAM is not close to full. This is true even if the machine were just booted. No apps run yet. 200 MB free physical, and yet there is still some swapfile usage. I always thought that the swap was only accessed if physical memory was all being used. Well, on my machine that's not true. And I imagine it's the same for anyone using Win98.

Anyway, after applying the tweak mentioned above, Cacheman shows that there is zero swap file usage from boot-up. I don't think I've run a program since then that has come close to swapping out to disk. So, it certainly appears to work as advertised. Until someone can explain to me why it doesn't, I'll continue to use it.

As for whether to let Windows handle it or set a fixed swap... I can't say for certain whether there is any speed to be gained doing either way. It seems alot of people recommend the Windows Way including the tag line "Windows does a better job of it". Really? The fact of the matter is that allowing Windows to handle your swap causes the swap file to be continually re-sized as needed. This of course, will lead to excessive fragmentation. Resulting in lower disk performance, as the reads must be done over more disk space.

It's quite possible that in two fully de-fragmented drives, there may be no difference in performance regardless of virtual memory method. But unless you de-frag every day or two, it seems to me for that reason alone a permanent swap is the way to go.

Thanks again guys. I have the System-monitor running in the background now, and will check if, how, and when the swap file is in use. As the Major recommended, I have set my system to act as if it's a "Network Server", and will fix the swap file to let's say 200MB, and will see.

Honestly, about editing the system.ini, I am a bit too cautious to do that, can't explain.
Thanks anyway!

This topic has me very confused. I keep hearing anecdotal evidence that ram beyond 128 improves performance but then I read articles like this http://firingsquad.gamers.com/guides/memoryperformance2/default.asp that show virtually no improvement in games with 256 vs. 128mb ram.

Check out the link and tell me what you think.

The people who say that 256MB RAM does nothing for their system, are usually running high speed (800mhz+)CPU's and 64MB (or DDR) video cards, along with pc133 RAM. Pc133 RAM runs one third faster than PC100 RAM, meaning it can do the work of, oh say, 170 MB of PC100 RAM. Add to that the 64MB video card, and they rapidly cross 200MB of RAM available for their system. No wonder then that another 128MB RAM doesn't help them. Add to that, most of these speed conscious builders are also using a 7200rpm HD, instead of a 5400rpm HD, which gives their swap file usage a speed increase of 50%. (The HD runs 50% faster, allowing a faster acces time.)
For those of us with older or mundane systems, more RAM gets our programs off the HD and into physical RAM, where it can be accessed much faster. So what if you spend $90 for another 128MB of RAM; how much does a new system cost?

This a very interesting topic!

I have a 450MHZ system with 64megs of RAM and am curious if I can utilize the tweeks to force windows to use more physical memory to improve my overall performance? And would it be worthwhile doing?

Thanks

Ogdens:

Your best bet would be to at least double your RAM. Then try the tweaks.
By going from 64 to 128, you'll notice huge difference in load times etc. At least I know I did.

BTW, I've heard of upping Virtual memory by 2x's your physical RAM, but never 2.5
