Does anyone know the answer to this? I seem to recall hearing that Windows 98 can only be used with up to 768 MB of memory. I am curious because I have 2 512 MB PC2700 (Kingston HyperX) sticks. My board (A78NX Deluxe) works fine with 1 installed but I get memory failed messages during the POST if I install the other. I really am not sure that I want to upgrade to XP or 2k as I really only play games and have heard a lot of people say that they have had problems.

The Win9x OS's only support up to 512MB, you can run WinME higher but may have problems. Window's 98SE supports up to 512MB, I've never heard of anyone able to run it with more than that for any length of time without have major problems. If you want to use 1GB XP or the 2000 series is your best bet.

Thing is that the 9x kernel does not support/cannot adress more than 512neg. You can put in 4gig, but it will still not be able to use more than 512meg.

To use more than that, you'll need a Win version based on the NT kernel, ie NT3.x and above or 2K/XP. the NT kernel also supports SMP.

Hope this helps

First off, if youíre getting memory failed messages during the POST, then it doesnít matter what OS youíre running, thatís a more low level problem. Could be a chip, slot, or BI/OS hitch.

As for your original query, this has been a serious matter for debate over the years and I think it comes down to the motherboard and the brand of RAM; and it doesnít seem to make any difference if you use decent quality kit or not. Iíve heard people swear that itís anything between 256 and 600. Itís become generally accepted over the last year or so that, in many cases, you can get it up to 512, but Iíve seen machines that have bombed out well below that. Myself, following a lot of trial-and-error (more than 30 different machines), Iíve come to the conclusion that most of the time, itís 384Mb -- thatís a 256 plus a 128. Now, I donít offer that as an all-encompassing maximum, itís just that 384 is the amount that Iíve found works most stably over the most different combinations of RAM/Mobo. If you desperately *NEED* more RAM than that, on a machine that ďmust haveĒ 98 on it, then youíre going to need to do a little trial-and-error testing yourself.

As a side note, I use 2k and I basically play games on my machine and donít do much else with it (Unreal/C&C/NWN/AvP2/Splinter Cell/WC3/Etc). The only problems are with DOS games (the ones that ran in the old 4GW shell), and some of the first DirectX dependant stuff that used to try and detect if you were running NT, which then detects 2000 as NT and decides that you canít load a high enough version of DX and bins out without giving you the option to bypass it :( The only one that springs to mind in that category is Incubation. Aside from that, it runs just fine. Add to this the fact that 2000 would make MUCH better use of your hardware, and Iíd say itís worth the upgrade.

The problem with your post is probably the asus motherboard. I've got the same one and apparently the board is not so great when it comes to memory compatibility. Check this post for asus memory issues

Once you actually boot into 98 though like everyone else said the extra memory won't help you much.
