eram's Introduction

ERAM

ERAM v2.30 is an Opensource RAM Disk made by Hideaki Okubo (okubo at msh.biglobe.ne.jp) with the source code comments translated by Katayama Hirofumi MZ (katayama.hirofumi.mz at gmail.com) and some modifications made by me thanks to help from a member of community.osr.com. It has a size limit of 4 GB that uses page/non-paged/external RAM. You can use it for storing temp files, browser cache, etc. in order to speed up the programs that use those files.

Install Instructions

Download from the Releases section (available at https://github.com/Zero3K/ERAM/releases)

x86 (32-bit)

Run the ERAM_x86.exe.
Follow the instructions.

x64 (64-bit)

Run the ERAM_x64.exe (you might have to run the Installer with Driver Signature Enforcement Disabled for it to install without any errors).
Follow the instructions.

After installing, the RAM Disk will be available as the R: or Z: drive with a size of 1 GB (for 32-bit OSes) and 4 GB (for 64-bit OSes) which can be changed as you see fit by running eram.cpl by pressing Win + R.

Build Instructions -

Download WDK (Windows Driver Kit) 7.1.0 from https://www.microsoft.com/en-us/download/details.aspx?id=11800.
Extract the ISO using 7-Zip, etc. to a directory of your choosing.
Run the KitSetup.exe located in the directory it was extracted to.
Click Full Development Environment.
Click OK.
After the install has completed, you can find the Build Environments in the Start Menu in Windows Driver Kits\WDK 7600.16385.1\Build Environments.
Open the proper Environment depending on what OS and CPU architecture you are building for (Only the Checked Build Environment works for now).
Change the directory to the location of the source code (for example, cd C:\ERAM).
Type build and press Enter.

eram's Issues

Translate Source Code, etc. to English

It would be nice if someone who knew Japanese could do that.

err1501 The process cannot access the file because it is being used by another process.

After installing ERAM, with no further instruction from the installer or github, I try to execute C:\ERAM\install.bat with an administrator CMD and I get this error:

C:\ERAM>install.bat
Device node created. Install is complete when drivers are installed...
Updating drivers for *err1501 from C:\ERAM\eram.inf.
devcon failed.
The process cannot access the file because it is being used by another process.
        0 file(s) copied.

I tried to restart my computer, still the same error.
Tried to delete all the files in C:\ERAM and it worked so I guess the file that cannot be accessed is somewhere else.

How should I install this software properly?

Where is "download in the Releases section"?

Where is "download in the Releases section" noted in README ? GitHub Releases are not enabled for this project.

How to download?

A file still has Japanese text in it

subject

The file in question is at https://github.com/Zero3K/ERAM/blob/master/eramui/eram.vcxproj. Please translate it when you can. Thanks in advance.

Better translation of "OS Outside Management Memory"

"OS Outside Management Memory" is too long. Is there any better English translation?

Requesting help with getting it to work in ReactOS

I have managed to learn that the FAT16 file system that it initializes itself with when loading in ReactOS isn't working properly with it. It complains of the SysType being wrong. When I replaced fastfat.sys with the new version available in the fastfat_new source directory, it works properly. I would like it if someone could do one of the following:

Add a registry option for choosing whether to use a FAT12, FAT16 or FAT32 file system when loading.
Remove FAT12 and FAT16 file system support from it so that way it ends up using a FAT32 file system when loading.
Adding code to it for it to recognize that ReactOS is being used and use a FAT32 file system instead of a FAT16 file system.
Fix the Sector 0 that it writes to when making the disk (in other words, have it contain the info that Windows writes to it).

Compile x64 version of the Control Panel Applet in Visual Studio 2017

It would be nice if it were possible to do so.

Uninstaller doesn't remove C:\ERAM folder

After uninstalling, the C:\ERAM folder remains with all the contents inside.

Fails to install on Windows 10

I pass all installer steps for ERAM_x86.exe, it says install is ok, but new drive letter doesn't appear, I see no way to start it, no error message. C:\ERAM\install.bat doesn't help, even under Administrator.

Compile more up to date binaries/add beta releases?

I was wondering if Zero3K could add more recent stable/beta release as the most recent is closing in on being 521 days/1.42 years old and I see much more recent changes to the source. Would that be doable?

I see some pretty significant changes this year . Are they stable enough to release binaries for them?

Improve the read/write speed of it

It would be nice if that were to be done (if possible).

Benchmarks

Please add screenshots of them to this issue. Thanks in advance.

Make the Control Panel Applet compilable by the WDK

It would be nice if the Control Panel Applet could be compiled by the WDK mentioned in the Readme so that way It'll work in all Windows versions without having to use external libraries.

How can I uninstall?

ERAM_x64.exe on Windows 10
I want to uninstall but can't find the way out.

Suggestion: GPURamDrive uses graphics card VRAM for cache; integration

Hi Zero3K

I'm not a dev.
I just want to make you aware of GPURamDrive:
It enables one to use the, mostly inactive unless gaming etc, VRAM on a graphics card as a Ram Disk.

As most people's DRAM is otherwise occupied (prefetch, superfetch, etc) using RAM that is sitting idle makes a LOT of sense..!? :)

The software is proof of concept and thus quite slow, but can probably be adapted to ERAM and optimised quite easily..??

Original software Link:
https://github.com/prsyahmi/GpuRamDrive
But it does NOT work on AMD Graphics Cards.
Here is a version that does:
https://github.com/brzz/GpuRamDrive/releases

No way to uninstal

Something installed... and i dont know what... can u take me clear instruction what i need to delete?

How would I installed the build output

Build output is the sys file, the driver. How would I install that? There is not any inf file in the project as well, which makes me wonder because there are issues about translation issues of the inf files.

How to install?

Defects found when building it

WDK 7.1.0 has found a bunch of defects in its source code when it was being compiled. The list of them is attached.

eram_defects.log

Improve GUI of its Control Panel Applet

The following improvements should be done to it:

Change the font used by it so it matches with the font used by rest of the properties of the "ERAM for Windows x86/x64" device that is listed in Device Manager.
Make the Disk size option have a radio button that lets the user switch between KB/MB/GB (Kilobytes/Megabytes/Gigabytes) to make it easier to specify how big the RAM Disk should be.
Have the currently selected options be filled in (they are blank at the moment even though they are set properly).
Split the Option key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Eram\Parameters into multiple Registry Keys so that way the Option key can be removed.

By the way, the source of the Control Panel Applet is in the eramui folder.

BSOD on Windows 7/10 64-bit

It crashes when loading the OS with it active no matter the size that was chosen.

How to uninstall?

Hello,

I tried to install it on m Windows 10 (Upgraded to Windows11) and while the installer say that it installed, I do not see any drives (R or Z) and also I do not see how to uninstall it.

Please help

Issue with compiling it with Visual Studio 2017

When I compile it for x64 architecture in Visual Studio 2017 with the attached ZIP archive which contains the project files used, the resulting driver doesn't load in Windows 7 but loads in Windows 10.

ERAM-VS2017.zip

not a issue

sry for writing here. i saw u interesting in reverse tethering (gnirethet). u can try and test my impl of reverse tethering https://github.com/vvviperrr/SimpleRT, i will be very appreciated.

Not work for me

Hello. Trying to install your program latest version. Windows10 x64 Ukrainian version

Managed to disable windows forced driver signature check, and ram disk was created after install, but when I try run options eram.cpl it writes "Cannot open registy key" (but Eram registry key exist in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eram).

When PC was restarted in normal mode ram disk was not created. Options still not reachable with "Cannot open registy key" error.

Installer instructions do not make any sense (x64)

I run the exe which downloads, I click through the wizard to the end.
Now what? Instructions here say there should now be a new mapped drive - there isn't any - and that eram.cpl can be run from the console (it can't).

Now I may have missed a step. But that isn't my fault, it is the fault of the installer, which should do all installation steps for me (it's an installer), and then start any user interface that is available.

The user experience is mystifying, all users will do is (like me) try it, fail to get it working, and move on to another ramdisk tool.
