Win98 Memory Limitation?

I've heard that Win98 will not recognize more than 512 megabytes of RAM. Is this true?

Thanks,
T.

Actually it's true and false. Windows 98 will recognize the 512MB of RAM, but it is not capable of addressing over 128MB properly. Basically, if you have over 128 your wasting your money. Upgrade to Windows 2000 or NT 4.0 to use the memory to it's fullest.

Hey, Ron where did you get that information from? I have never, ever heard of such a thing. So if you can post where you got this information from, I would like to read it. I know off plenty of boxes that run Win Me and have well over 128Megs and work properly. Just want to know where you are getting your info from cause I don't think it is correct.

Windows98 will recognize up to 2 GB RAM, but you will probably run out of system resources before you could use it all. Windows NT/2000 has no such limitation on system resources, so, yeah, it can use the memory better. But my Windows98 machine has 384 MB RAM and uses it quite happily.

Greg's response is the correct one. Win98 doesn't need (or effectively use) RAM more than about 256 to 512 MB unless you are running a VERY memory dependent application (like a CAD). As he says, you usually are going to exhaust your 128 K of system resources memory long before you can use higher amounts.

Thanks, rac. Yeah, with RAM prices being so low, I decided to bump mine up to the max my motherboard would take, 384 MB. With System Monitor open, I tried to see how much I could have open at the same time. I opened the most memory-hogging apps I had (Office, PhotoShop, 3D Home Designer, etc.). I had about 15 different apps open at once, but I decided to quit when I got down to only 9% system resources available. I still had about 100 MB RAM free. So, no, even with "only" 384 megs, I probably couldn't use it all. Maybe if I did CAD or 3D graphics design, I could use it, but not for what I use the computer for. I always have zero swapfile use, which is nice. The rest is just bragging rights.

I got the info from an old boss of mine. He is pretty much a windows guru, so I took his word as gold. As you state in your posting you have no problems with Win ME boxes running higher amounts or RAM. That's cause they're ME, which is based on NT technology not Window 9x.

My bad, see what happens when you work, stop typing and come back. My brain was in the ME message board at the time. See let me say this. Win98 not Winme is what I should have said. Anyways, Thanks for the responce. Also to clear something up. The Windows Sytem Resources are a set limit, they can't be increased by adding more memory. You can have 1gig of memory our 64Megs, it doesn't matter. The Windows System Resources will be equal no matter what. Now Windows NT does not have a resource limit. Hell, last night running Windows XP, I had 43 IE windows open at one time. It was pretty cool and this is something you just can't do on the Win 9.x kernel, I don't care how much RAM you have becaue the system resource will run out.

Hey folks,
by design the vcache driver is limited to 800 MB. So the most mobos will work with 3*256 MB = 768 MB. But, in some boards the video is cached too (Aperture size). So it maybe that the vcache runs out of virtual cache addresses. If you try to open a DOS window then, you will be told that there is not enough memory.
This is true with all versions of 95, 98, 98se and me.
You can limit the amount of mem which vcache uses in system.ini. Search for [Vcache]. Edit 'MaxFileCache'.
If you have more than 768 MB installed (due to a double boot with NT or w2k), you should limit windows 9x by editing system.ini with a apropriate entry of 'MaxPhysPage' in [386Enh].
Also see MS Knowledgebase Q253912 and Q184447 for more information.
If you ask Microsoft, they will not give ANY support if there is more than 512 MB plugged in!
