Introduction

The little ctcm program from the German ct-Magazine is an extreme helpful tool to find out about your motherboard performance. The most important thing to do for a motherboard is to transfer data as fast as possible from one device to the other. In particular this is the transfer process between CPU, L2 Cache, Main Memory and PCI Devices. Your CPU can be as fast as it wants, as long as your M/B isn't able to get the data quickly from the memory or the graphics card to the CPU and vice versa, your computer will be as slow as a slower CPU in a fast M/B.

Exactly this is measured by ctcm. It checks the speed of your L1 Cache (which only is depending on your CPU speed really), of your L2 Cache - and here it checks all the different cache conditions - and of your main memory. You are also able to check the speed of the data transfer to and from your graphics card to learn about the speed of your PCI bus, but here it is also very much depending on your graphics card itself.

When you see the results, you have to take in consideration that one of the crucial things for your cache and main memory speed is the bus tact (or bus speed). As you know from my Pentium Reference Table, the bus speed is not the same in all Pentium computers, it depends on the CPU speed. A Pentium 120 has a bus speed of 60 MHz and has therefore a slower memory and L2 cache speed than a Pentium 100. A Pentium 133 has just as a Pentium 200 the same bus speed of 66 MHz - therefore the cache and memory speed is the same, except of the L1 cache.

How to use it

You have to use this program in DOS !!! No DOS-Box, no virtual mode device manager ! You'll need an Extended Memory Driver though, HIMEM.SYS.

If you still should use Windows 3.1 (or WfW 3.11), you normally just have to leave Windows - as long as you didn't load EMM386, QEMM or any other virtual mode device manager in config.sys. If you should have, ctcm will tell you. The probably easiest way to run ctcm is to create a boot disk with nothing in the config.sys. You won't need a autoexec.bat, but if you're smart, you put the line "C:\ctcm\ctcm.exe" as only line in the autoexec.bat, where "C:\ctcm\" has to be replaced by your ctcm directory - wherever you store it on your hdd. In this case the computer will boot and straight away run ctcm.

In case you are a Windows 95 user (like me), you either anyway have a dual boot option to boot into old DOS, or you haven't (tsts !!!). If you should have the boot menu, you just choose Start in MSDOS Mode. If not, you either press F5 continuously after the BIOS POST, cause that'll get you into the boot menu, or you can get into MSDOS mode from Windows 95, via choosing Start Computer in MSDOS Mode from the shutdown menu or you'll also have to create a boot disk as described above.

The real cracks have got a boot menu for their old DOS (as myself of course ;-) ) and certainly have an option to boot with only the XMS driver, as you need it for lots of the modern games nowadays. In this case it's easiest of course, you boot this way and run ctcm, basta.

The results should speak for themselves, after all I eventually translated that nice little program ;-).

There are quite a few command line options for ctcm, but these I will explain at a later stage - or translate the readme file. You wont need any command line options for the results I would like you to send back.
