Note: As with any Win32 process, CHKCPU32 is limited to 32 Threads under 32-bit Windows. Physical CPU count, Core count per CPU, Total number of logical processors (=Threads). Use CHKCPU if 8086/8088, 80286, 386, 486, NexGen, or Vortex86 support is needed.įor most CPUs, CHKCPU will display the multiplier and busspeed in Real mode DOS only.ĬHKCPU32 shows the processor topology in a system on 3 levels: Support for NexGen and UMC CPUs has been dropped from CHKCPU32. Yes, any 32-bit or 64-bit Windows versionĬHKCPU32 has better speed indication accuracy under WinNT4 and later Windows versions.ĬHKCPU32 is 64-bit Windows aware and makes use of additional CPU Topology support of 64-bit Windows. Main differences between CHKCPU and CHKCPU32 FeatureĬHKCPU32 is the 32-bit successor of the 16-bit CHKCPU DOS version. In addition, CHKCPU32 can display the number of CPUs and Cores in a system. This is especially true under WinNT4 and all later Windows versions. Because CHKCPU32 is a true Windows program, it gives a better speed indication accuracy on high speed CPUs than the 16-bit CHKCPU when run under Windows. For most CPUs however, the Clock multiplier and Bus clock speed can only be indicated in 'Real mode' DOS.ĬHKCPU32 is designed to run in the command window of any 32-bit or 64-bit Windows version (Win95 or higher). CHKCPU is designed to run under DOS 5.0 or higher, or any 32-bit version of Windows. The programs CHKCPU can be run from the DOS prompt or from a DOS-box within Windows. You can download both programs here and in each zip a text-file is included with more information about the program and the changes I've made in this revision.īoth programs have the same update status regarding the CPU model data, and they are both freeware. Both versions give approximately the same text-based output. I've named the Win32 version CHKCPU32 to distinguish it from the DOS version.
On the other hand, CHKCPU is also useful for checking the CPU type and speed on a given machine and, due to its text-based output, information from CHKCPU can easily be used to get CPU info from each machine in a network by calling CHKCPU from the network log-on script or via a remote execution tool.ĬHKCPU comes in two flavors, a DOS version and a Win32 console mode version. I wrote a utility, called CHKCPU, to have an easy check on these settings. by Jan SteunebrinkĬPU Identification Utility - CHKCPU v1.27.1 - 25th anniversary 'Retro update' edition This CHKCPU 'Retro' update is the first version to support 16-bit CPUs, and more 386/486 CPU models as well IntroductionĪfter a CPU and/or motherboard upgrade, it can be difficult to find the correct motherboard jumper or BIOS settings for clockspeed, clock multiplier, and (for 486 only) internal cache Write-Back/Write-Through mode selection.
