Q304943 - Computer May Reboot Continuously with More Than 1.5 GB of RAM *
Q311871 - A blue screen appears when you start a computer with 1 GB or more of RAM *
* These latter two articles are misleading in that they include the statement: "Windows Me and Windows 98 are not designed to handle more than 1 GB of RAM", which simply is not true. Q311871 is included here just for the sake of completeness, and ought to be disregarded, as Igor Leyko, in 2005, had already pointed out.
** Likewise Q181594 is also misleading (see this post) and is included here just for the sake of completeness, since it gives the impression that Win 95 can use more than 1 GiB of RAM without any patching, which is not true.

[dencorso]

As of Dec 28, 2012, there are 48 machines, owned by 34 members, running Win 9x/ME with more than 1 GiB RAM.
Of these, 25 machines are multiboot setups.

This list is sorted by amount of onboard RAM, then by member username in alphabetic order. An arabic numeral in parentheses beside the member username indicates machine number, for members having more than one machine in the list. Similarly, a roman numeral beside the member name denotes another configuration of the same machine, different enough to warrant another entry in the list. Since the aim of this list is to provide examples of working configurations, I see no point in removing a configuration proven to work just because the user found another, even better, working configuration (but such different configurations count as one machine only, of course, in the tally at the top of this post).

Very nice thread, realy.

Too bad I can't make it to the list since my Ram installed is "only" 1GB....

Does it count if you are running windows 98 in vista using "Virtual PC"? I can manage the ram available to Windows 98 from the Virtual PC console. I'm running with 1.5 in vista with a quad core, I can try giving all the ram to windows 98 but I'm not sure what that will do just yet.

Well, I don't know of any report about it being done before, so it sure is an interesting experiment! Since you're not running it on a day-to-day basis, it'd require a proof of stability. Hence, if you succeed in getting it to run, have it run stably for more than 15h and get a perfect shutdown at the end, I can create a new category in the list, which I'll then divide in "Runing on Virtual Machines" and "Running Directly on Hardware", and you'd be the first user on the new category. And your system description should include data for both the real hardware and the virtual hardware windows thinks is running on.

You know, I'm not sure it technically count as running with more than 1GB memory, if you're actually limiting the memory and not using it.

I'm not sure if it's possible to actually get more than 1GB memory used by 9x, I'm not even sure which file you'd have to patch (probably a vxd), but it would be pretty cool if someone ever found out.

It is definitely possible. I have actually used 3647MB of RAM with Windows 98 SE using my Patch. It actually requires at least 2 vxd files to be patched. If you look at my entries in the list at the beginning of this thread, you will notice I am not setting any limit on memory usage.

The point is that when you put more than 1GB of RAM in a PC with Windows 9x, problems start to occur even when limiting the amount of RAM by using MaxPhysPage.
Various other parameters or drivers are generally needed to become stable. The more RAM, the worse the problem...

I currently have 1176924KB (1149MB, 1.122GB) of actual usable Windows memory reported from Windows Properties without any special patches installed. I've never seen Windows work so fast!

My mobo has 1.5GB installed. The manufacturer says that you can use up to 2GB of PC100 (four modules), but at PC133 (which I'm using), it is only stable with 1.5GB...
So, sometimes it also depends on your mobo...

vmm32.vxd (real mode), vcache.vxd, vmm.vxd: 4.10.0.2222 with RAM Limitation Patch 5.0

Doesn't this qualify as a limit?
When I say "without limiting" I mean that you'd actually be able to open a program allocating 2GB of RAM or more, without resorting to swap-memory (e.g. with virtual memory disabled). A RAM limitation patch won't do that...

I would think a solution that would do that would at least require patching himem.sys or something... (sorry for the abuse of "would")

So far, I know only one person who had a system that did not work stably with 2GB or RAM using my Patch. I rewrote my Demo so people could check first.

That is approximately where the first memory table overflow occurs. That limit varies slightly with configuration and use of Safe Mode.

My Soyo P4VGA has this problem. With 2GB the computer either doesn't boot or fails my memory test program.
This has nothing to do with Windows of course.

When I said FULL USE, I meant it. I allocated over 3GB of RAM without using Swap. A single Program is limited to 2GB so I needed 2 Programs running.
The Patch doesn't set a RAM limit, it eliminates the limitation.

My earlier version did patch HIMEM.SYS because there was a problem at 2.9GB of RAM. My current version does not need to patch HIMEM.SYS

My point was, that without patching the Windows VMM, configuration gets somewhat tricky the more RAM above 1GB is installed.
However, this topic highlights that it is possible to use Windows 9x on a PC with more than 1GB of RAM with just public domain information and patches (and even get over 1GB available to Windows).

rloew, I think your work is outstanding... but your results are here for comparative purposes only and (Forum Rules 13) not for actual product promotion.

I'll give this a shot sometime...

@ RetroOS, why a dualie? I have a dual-PIII machine too and it's really nice, but you know 98 can only work with one CPU anyway...

I multiboot with Windows XP, so I get both PIIIs then.
Windows 98SE is my primary OS, and I only use Windows eXtra Problems for the odd task.
It's also handy to confirm hardware operation if I have a problem in 98SE with a new piece of hardware...

some specifications for my computer:
- adding swapfile to ramdisk helped with 3d performance - 12.5 percent improve in 3dmark2001
- this is quite high-end gaming machine - all the best for the MOBO and Win98
- its purpose is mostly gaming and multimedia - everything fueled with overclocking

[rloew]

I have run some tests on RAMDISKs and XMSDSK in particular.

Conventional RAMDISKs use XMS memory, displacing Windows from said memory.

Windows 98SE maps this memory into the System Arena in the last GB of Virtual memory. This memory is also used for File Caching and VMs.

The larger the RAMDISK, the less File Cache is available. Looking at the list Dencorso assembled, you can see that the people who used a large XMSDSK in their setup ended up with a much lower setting for MaxFileCache. This limits RAMDISKs to not much more than 512MB so they can't be used to support 2GB of RAM without using MaxPhysPage. Some people have had problems relying on MaxPhysPage to limit memory.

XMSDSK has a bug in it that makes it work improperly above 2GB of RAM when the /T option is used.

I am working on RAMDISKs that don't use XMS Memory. One should be able to use the 64-Bit Memory in AMD Computers having 4GB or more RAM.

@RLoew: It is reassuring to see that your tests support my conclusions (in posts #21 and #25, here: link) from my own tests and also from those reported by diskless (link) on where Windows maps the memory it doesn't control and the consequences this has.

This amounts to stating that 1.5 GiB is about the maximum RAM that can be used fully by Win 98SE (without the RAM Limitation Patch) plus XMSDSK: 1158 MiB or a little less to VMM and 378 MiB or a little more to XMSDSK, because much more will leave no space for the File Cache and any DOS Boxes. It should be added that, all other things remaining the same, it is also a good idea to use HIMEMX.EXE instead of HIMEM.SYS, because this allows for more DOS Boxes (as found out by xRayeR and confirmed by vick1111, see posts #70-#82, here: link), for reasons that are still not totally clear.

Win ME probably can do better, in this respect, since it is able to detect about 2 GiB, so probably it may also accept a 512 MiB XMSDSK, to attain about 2.5 GiB of fully used RAM...

Of course, the list in post #1 of this thread shows clearly that to run Win 98Se with lots of RAM, with part of it unused, perhaps for a multibooting machine, not only is possible, but is actually being done in a day-to-day basis by some of us.

I have completed work on a 64-Bit RAMDISK as well as a 32-Bit RAMDISK, neither of which use XMS Memory.
Since Windows does not know this memory exists, it doesn't manage it or allocate precious System Arena space for it.
I have been able to create and use 2GB RAMDISKs without problems.

I haven't as yet determined the difference in behavior between HIMEM.SYS and HIMEMX.SYS, there isn't anything obvious in the source code for HIMEMX.

[rloew]

I have done some further research on HIMEMX.

HIMEM is recognized by Windows during Windows Startup, so it is hooked, letting Windows take over management of all XMS calls. Any XMS Memory that was
allocated before Windows Startup is not included in available Memory for Windows but is mapped into the System Arena so Windows can support the Programs
and Drivers that reserved the Memory. Since most RAMDISKs use XMS Memory, they tie up System Arena space. This is why a large XMS based RAMDISK
cannot be used because the System Arena runs out of space.

HIMEMX is not recognized by Windows so calls to it are executed in Virtual Mode. HIMEMX uses the BIOS Interrupt 15 call to manipulate Extended Memory.
Windows hooks this Interrupt so it can manage the Memory. Windows uses the standard XMS calls to take over the Free Memory during Startup. The difference
is that Windows does not know about XMS Memory that was Allocated before Startup so it doesn't reserve space in the System Arena for it. This is why there
seems to be more space for DOS Boxes etc. The problem is that actually using this Memory invokes the Interrupt 15 call which then causes Windows to allocate
Pages to the System Arena to manage it. Reading or Writing a Large RAMDISK quickly fills up the System Arena and leads to a crash.

You can setup a large XMS RAMDISK using HIMEMX but your system will crash if you try to fill it up.

I also observed a problem combining HIMEMX with EMM386 whenever exceeding approximately 1408MB. EMM386 appears to allocate all of the XMS memory and
then release what it doesn't need. Above 1408MB EMM386 does not release approximately twice the amount of Memory above 1408MB, so the available memory
actually decreases as the total amount of RAM increases.
