The famous ram patch by rloew is now available to the public through permission of his son! Rloew has been known for his fantastic advancements onto Windows 9x that could not be imagined to be possible! His ram patch is probably the best known of his many achievements. With this, Windows 9x systems can utilize up to about 4gb of ram. Install and enjoy!

Features:
-Use up to 4gb of ram on Windows 95, 98, and ME
-Enhanced system stability >512MB ram
-Simple installation
-Compatible with any Windows 9x PC

Requirements:
Windows 95/98/ME

Instructions:
1) Unzip files
2) Open PATCHMEM.EXE
3) Reboot Windows
4) Enjoy

Components:
PATCHMEM.ZIP

Notes:
-If using a physical computer, be sure your motherboard natively supports the amount of ram you desire. The patch is ineffective if the bios cannot see all the ram.
-Windows 9x’s user memory space is limited to 2GB due to being hard-coded.

As dencorso said, right after installing 95/98SE, just run PATCHMEM.EXE /M and forget about anything else. Don’t bother with SPLIT8MB, Min/Max FileCache, or MaxPhysPage.

For many years been running 98SE without ever tweaking FileCache settings, even before the RAM patch became available to public.

«oddly» for me, i still need to use 1/24 of system ram for minfilecache and maxfilecache. at least from my testing, i noticed that when i removed the entries, even with rloew’s patch, it functioned oddly such as iexplorer.exe causing a illegal operation / page fault, and it usually was related to ole32.dll. another weird issue ( not because of not having the filecache settings ) was with using a older version of vlc player that was able to launch successfully, i don’t remember the version as i deleted them shortly after, i think it might have been 0.5.3, if not that, then .4 version that launched, and played a mpeg video shortly before making some weird slight high pitched noise and then exited and complained about a invalid page fault in directx.S0. i don’t think the vlc player .8.6d in specific is related at all to system settings or hardware, as i noticed when it tries to install, it mentions not being able to load a certain file ( this happened on other computers ), but oddly, older versions don’t seem to have this specific issue, yet still don’t run properly. the TCPMP mod player worked fine of brief testing, and i also tested winamp 2.95 without issue for a sample mp3 file. 

another strange but new issue i encountered was wmi9x failing to load certain files, cimwin32.mof, msi.mof, etc. perhaps these issues might be related to ACPI in some way? also, the reason why i mentioned the 1/24 ram and filecache settings is because without minfilecache and maxfilecache settings of 1/24 of ram, wmi9x wouldn»t even install, with GLB6362 causing a invalid page fault in ole32.dll. i then added minfilecache=86000, and maxfilecache=86000 ( having 2048 MB of ram installed ), rebooted, and was able to install wmi9x, but with the errors related to not loading cimwin32.mof, etc. there was also a invalid page fault with a certain version of vlc i tested, possibly 0.6.2, but instead of it being for ole32, it was mentioned in module <unknown>. so other than wmi9x and those vlc players, i don’t think i had any other large issues, at least presumably, i believe the explorer errors were cured from using the appropriate minfilecache and maxfilecache settings, but how other people can run their systems fine without it, i don’t know. 

ironically, for maxphyspage, i did not add the entry in this build, but what are the chances that this would have any effect on the related problems i have? i may need to test this out, despite rloew’s patch notes mentioning ( at least for 98SE ), for it be removed from system.ini settings, though not specifically mentioned for windows 95. as for patchmem itself, i’ll pass on that information to the next configuration to run patchmem.exe /m. however, i was wondering, for the part he mentioned to copy patchmem to the windows folder, is it ok if it’s copied to the c:\windows folder? also what’s the difference between using that switch command vs just double clicking the executable? reason why i ask is because i didn’t use the switch method, i simply double clicked patchmem.exe to install from c:\windows where i copied to.

Windows 3.11/9x/Me на компьютерах с оперативной памятью более 512 МБт

————————————————————————

Описание проблемы:

В 32-х битном защищенном режиме кэш-драйвер (Vcache) в Windwos пытается создать максимальный размер кэша, столько сколько доступно было при старте ОС.

Кэш-драйвер резервирует достаточно памяти адресов для доступа к максимальному размеру увеличения кэша.

Этот диапазон адресов находится в виртульном адресном пространстве от 0xC0000000 до 0xFFFFFFFF (3 to 4 гигабайт) системной области.

На компьютере с установленым большИм объемом RAM максимальный размер кэша может быть больше, чем все доступные адреса кэш-драйвера в системе, в рзультате будет недостаток доступных виртуальных адресов для нормального функционирования ОС.

Варианты решений:

а) Ограничить максимальный размер кэша в системе до 512 МБт или менее.

б) Или установить лимит максимально возможной доступной памяти в системе.

в) Или ограничить инсталированную в компьютере RAM.

—————

Решение с ограничением размера кэша:

1) Открыть System.ini в редакторе типа Notepad, либо в любом ином текстовом редакторе или из MS-DOS сессии.

2) Нати в этом файле секцию [VCache]

3) Изменить (добавить) параметры MinFileCache= и MaxFileCache= на требуемые значения. Размер указывается в килобайтах.

Например: Для большинства систем максимальный размер кэш можно установить до 32 МБт. Минимальный по усмотрению.

[VCache]

MinFileCache=4096

MaxFileCache=32768
