ABCDEFG Posted September 3, 2017 Share Posted September 3, 2017 @98SE Yes i have CRT monitor and i use it for first machine, for other machines i use LCD... 1Gb is max without SYSTEM.INI mods. I just tried to see what's maximum but now with SYSTEM.INI mod, i used 1GB + 256MB and for 98fe maximum is 1086MB MaxPhysPage=44000, for 98SE max is 1150MB with MaxPhysPage=48000 if i put 2x1GB - 2GB It gives me BSOD And i did some "benchmark" on this machine with Quake III Arena with different memory modules and results are: 1GB+256MB @ DDR266 - 390 fps 1GB @DDR 333 - 398 fps 2x512MB @DDR400 dual channel - 438 fps Link to comment Share on other sites More sharing options...
rloew Posted September 3, 2017 Share Posted September 3, 2017 It behaved as expected. You need my Patch to use more RAM. Link to comment Share on other sites More sharing options...
pangoomis Posted September 3, 2017 Share Posted September 3, 2017 (edited) @rloew What about the problems I had when having 1GB of RAM without the VCache patch? Without the VCache patch 3DMark2001 SE did not work and older NVIDIA drivers (4x.xx, 5x.xx) did not work either, leaving a black screen after boot screen. Both worked with 512MB of RAM. The newest NVIDIA drivers (7x.xx, 8x.xx) did work without the patch That's why I encouraged everyone to use VCache patch if they have more than 512MB. Can you explain why those would fail with more RAM? Edited September 3, 2017 by MrMateczko Link to comment Share on other sites More sharing options...
rloew Posted September 3, 2017 Share Posted September 3, 2017 The 1152MB limit is due to Kernel Memory Database issues. It is separate from the VCACHE issue. Unlike the VCACHE issue, this cannot be fixed without Patching. I described the VCACHE issue in some detail recently in another post. It can occur if you exceed around 768MB of RAM. Video drivers can make a significant difference depending on how they handle Video Memory management. Microsoft set the Maximum File Cache to 800MiB, which is too large. My RAM Limitation Patch sets the default Maximum File Cache to 512MB or to a User specified Value. It can also be set by adding a MaxFileCache entry into SYSTEM.INI. The XENO86 Patch sets it to 512MB. Link to comment Share on other sites More sharing options...
dencorso Posted September 3, 2017 Share Posted September 3, 2017 Just a small correction, sorry! Xeno86's VCache actually sets it to 384 MiB. But accepts both bigger and smaller values, if set by adding a MaxFileCache entry into SYSTEM.INI. 17 minutes ago, rloew said: The XENO86 Patch sets it to 512MB. Not that it actually does make much difference, since all that really matters is being 512 MiB or smaller. Link to comment Share on other sites More sharing options...

Try 512MB = 2 x 256MB @ DDR400 dual channel and see what fps comes up if identical? Was this a two max memory slot MB? https://en.wikipedia.org/wiki/DDR_SDRAM DDR1 Bus Clock 100–200MHz Internal Memory Clock 100–200MHz DDR2 Bus Clock 200–533.33 Internal Memory Clock 100–266.67 Edited September 4, 2017 by 98SE Link to comment Share on other sites More sharing options...
