LegacyĬonnectix closed in 2003 after selling its flagship Virtual PC product to Microsoft. Connectix discontinued development of its Windows version as the negative publicity of the scam, combined with declining RAM prices, had effectively destroyed the market for such software. Syncronys went bankrupt in July 1998 before all its fines and rebates to customers could be paid. Lawsuits were filed and the Federal Trade Commission investigated the scam.

After selling as many as 700,000 copies, it was discovered that the software actually did nothing except write more swap data to disk with worse performance and report false memory savings, leading it to be called "placebo software". However, Syncronys Softcorp had brought a competing product into the marketplace called SoftRAM with a graphical user interface. SoftRAM - The Story of the Incredible RAM Doubling Scam (A Retrospective)Ĭonnectix attempted to bring RAM Doubler's success in the Mac market to the PC market with a version for Windows 3.x.

Version 8 was released in July 1998 and skipped version numbers to indicate its support for Mac OS 8. Even set at 1.0x, RAM Doubler's enabling of "file mapping" through the Code Fragment Manager on PowerPC-based systems would allow applications to use less memory than if no virtual memory had been turned on. The slider could be set from 1.0x to 3.0x to prioritize memory quantity vs. Version 2.0 was released in August 1996, introducing faster memory management and a new user interface that allowed users to select the amount of desired memory, up to triple beyond what was physically installed. The demand was driven by a worldwide spike in already high RAM prices driven by a factory fire in Japan. At least a Motorola 68030 processor (or a 68020 paired with a 68851 PMMU) was required to enable its memory management routines which doubled the amount of available memory over what was physically installed. Version 1.0 debuted for Mac users in January 1994 at the Macworld Expo in San Francisco. Only when all free physical memory was occupied, would it start writing swap files to disk, like virtual memory. RAM Doubler compressed less-used memory contents of background applications, and recovered free memory for use by the foreground application.
