ERAM 2 | 3 | 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. 4 | 5 | ## Install Instructions 6 | 7 | 0. Download from the Releases section (available at https://github.com/Zero3K/ERAM/releases) 8 | 9 | x86 (32-bit) 10 | ------------ 11 | 1. Run the `ERAM_x86.exe`. 12 | 2. Follow the instructions. 13 | 14 | x64 (64-bit) 15 | ------------ 16 | 1. Run the `ERAM_x64.exe` 17 | (you might have to run the Installer with Driver Signature Enforcement Disabled for it to install without any errors). 18 | 2. Follow the instructions. 19 | 20 | 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. 21 | 22 | ## Build Instructions - 23 | 24 | 1. Download WDK (Windows Driver Kit) 7.1.0 from https://www.microsoft.com/en-us/download/details.aspx?id=11800. 25 | 2. Extract the ISO using 7-Zip, etc. to a directory of your choosing. 26 | 3. Run the KitSetup.exe located in the directory it was extracted to. 27 | 4. Click Full Development Environment. 28 | 5. Click OK. 29 | 6. 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. 30 | 7. Open the proper Environment depending on what OS and CPU architecture you are building for (Only the Checked Build Environment works for now). 31 | 8. Change the directory to the location of the source code (for example, cd C:\ERAM). 32 | 9. Type build and press Enter. 33 | 34 | ## Benchmarks - 35 | 36 | ![ERAM Benchmark done on Windows 7 64-bit](images/benchmark.png) 37 | ![ERAM Benchmark done on a Windows 7 64-bit Virtual

However v2.21 and earlier, only the RAM in the range of n ~ 4095MB for safety measures 15 | And put a check that does not use, is the memory actually available in the NOLOWMEM environment 16 | It had become something less. 17 | So, at the time of PAE NOLOWMEM specified in the flow, such as if MAXMEM = 17 is specified 18 | I tried to add a control, such as fall. Since the number MB of the top of the 4GB space is used for PCI 19 | Available about real 4000MB memory ... might. 20 | Since the hand there is no over4GB environment, I do not know whether or not actually move. 21 | 22 | We had a fine information to Ten'yume forest Nagareirodori's. Thank you very much. 23 | Wall per 1.7GB is at least Ten'yume forest Nagareirodori's environment has been surpassed in the v2.21 time. 24 | 25 | This new driver, you can install the time being in a conventional INF file. 26 | 27 | It should be noted that, for the behavior at the time of NOLOWMEM specified without PAE is still in v2.23 time 28 | We misidentified the MAXMEM = n, but solution is unknown for now. 29 | 30 | And exclusion of the ACPI of memory (going to) v2.21 or later 31 | 32 | ACPI NVS, ACPI Reclaim is placed on top of the physical RAM by the ACPI BIOS. 33 | MAXMEM If not specified, these regions Loader Reserved next, from the OS 34 | Will not be used, but, at the time of MAXMEM = n specify becomes the OS unmanaged, 35 | You had to manage on their own. 36 | However, as the ACPI of the environment is almost standard, also information to the effect that it does not work properly 37 | It has increased. 38 | Although ACPI of information must be acquired by the so-called E820 I / F in the realistic mode 39 | Because from the NT-based driver can not call the BIOS, from the table in the memory 40 | It was to guess method. 41 | Table content is going to follow the ACPI BIOS specification 2.0c (2003/8/25). 42 | 43 | But there is no ACPI machines are only two on hand. 44 | Okay at hand two, but whether all right to the general public is unknown. 45 | 46 | Even then, by reducing the capacity of the RAM disk so as not to overlap with ACPI region 47 | The problem does not occur. 48 | 49 | This new driver, you can install the time being in a conventional INF file. 50 | 51 | - Two eyes of the corresponding to the driver installation (provisional) v2.21 or later 52 | 53 | Because there was a desire to try two put on trial, two eyes forced the 54 | I tried to be able to install. 55 | 56 | The new driver is the one first and two second is common, but the file name is in eram2.sys 57 | Become. Also driver name will Eram2. Windows2000 and later, such as the one first 58 | Rather than using the hardware wizard, it will be to the right-click of the INF. 59 | INF file, but it is placed under the 2ND directory, to avoid the hazard 60 | We changed the IN_ and extension. 61 | Return the extension 62 | Install the right-click 63 | Reboot 64 | 65 | [Important] 66 | Because of the preliminary version, you will not be able to change the settings of Eram2 from the screen. 67 | And a modification of the set of Eram in the reference, it will touch the registry. 68 | 69 | [Important] 70 | Because of the preliminary version, there is no uninstaller. 71 | It will be turned off and search for Eram2 from the registry. 72 | Files will be erased the eram2.sys. 73 | -------------------------------------------------------------------------------- /eramui/eramum.mc: -------------------------------------------------------------------------------- 1 | ;// 2 | ;// Message Definitions for ERAM 3 | ;// 4 | 5 | ;// Header 6 | LanguageNames=(English=0x409:eramue) 7 | MessageIdTypedef=NTSTATUS 8 | FacilityNames=(System=0x0FF) 9 | 10 | ;// Message Definitions 11 | MessageId=0x1 12 | Severity=Error 13 | Facility=System 14 | SymbolicName=ERAM_ERROR_FUNCTIONERROR 15 | Language=English 16 | Function %2 returned a failure.%0 17 | . 18 | 19 | MessageId=0x2 20 | Severity=Error 21 | Facility=System 22 | SymbolicName=ERAM_ERROR_MAXMEM_ALREADY_FREE 23 | Language=English 24 | OS-Unmanaged Memory is already released.%0 25 | . 26 | 27 | MessageId=0x3 28 | Severity=Error 29 | Facility=System 30 | SymbolicName=ERAM_ERROR_MAXMEM_MAP_FAILED 31 | Language=English 32 | Failed to map OS-Unmanaged Memory.%0 33 | . 34 | 35 | MessageId=0x4 36 | Severity=Error 37 | Facility=System 38 | SymbolicName=ERAM_ERROR_MAXMEM_REPORT_USAGE_FAILED 39 | Language=English 40 | Failed to notify usage of OS-Unmanaged Memory.%0 41 | . 42 | 43 | MessageId=0x5 44 | Severity=Error 45 | Facility=System 46 | SymbolicName=ERAM_ERROR_MAXMEM_REPORT_USAGE_CONFLICT 47 | Language=English 48 | OS-Unmanaged Memory is being partially used by another device.
