Frequency: 1.7–2.0 GHz; L2 cache: 2 MB (4 core) or 4 MB (8 core) L3 cache: 8 MB; Thermal design power: 25 W (4 core) or 32 W (8 core) Up to 64 GB DDR3L-1600 and up to 128 GB DDR4-1866 with ECC; SoC peripherals include 14 × SATA 3, 2 × integrated 10 GbE LAN, and eight PCI Express lanes in ×8, ×4, and ×2 configurations
However, with a multiple-level cache, if the computer misses the cache closest to the processor (level-one cache or L1) it will then search through the next-closest level(s) of cache and go to main memory only if these methods fail. The general trend is to keep the L1 cache small and at a distance of 1–2 CPU clock cycles from the processor ...
Available for Windows 7 to 11, or Windows Server from 2008 R2 to 2022; 32/64-bit x86 or 64-bit ARM. SoftPerfect RAM Disk can access memory available to Windows, i.e. on 32-bit systems it is limited to the same 4 GB as the 32-bit Windows itself, otherwise for physical memory beyond 4 GB it must be installed on 64-bit Windows.
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
Enabling PSE (by setting bit 4, PSE, of the system register CR4) changes this scheme. The entries in the page directory have an additional flag, in bit 7, named PS (for page size). This flag was ignored without PSE, but now, the page-directory entry with PS set to 1 does not point to a page table, but to a single large 4 MiB page.
The minimum cache size is 250 MB. In Vista or with FAT32 formatting of the drive, the maximum is 4 GB. In Windows 7 or later with NTFS or exFAT formatting, the maximum cache size is 32 GB per device. Windows Vista allows only one device to be used, while Windows 7 allows multiple caches, one per device, up to a total of 256 GB. [5]

The Windows Workstation version currently runs on only the 64-bit flavors of Windows 7, Windows 8.1, and Windows 10; 32-bit versions are not currently supported. The current version of CAS for Linux supports write-through, write-back, and write-around caching.
