About CPU cache RAM

The CPU must deliver its data at a very high speed. The regular RAM can not keep up with that speed. Therefore, a special RAM type called cache is used as a buffer - temporary storage. To get top performance from the CPU, the number of outgoing transactions must be minimized. The more data transmissions, which can be contained inside the CPU, the better the performance. Therefore,the 486 was equipped with a built in mathematical co-processor, floating point unit and 8 KB L1-cache RAM. These two features help minimize the data flow in and out of the CPU.

Cache RAM becomes especially important in clock doubled CPU's, where internal clock frequency is much higher than external. Then the cache RAM enhances the "horsepower" of the CPU, by allowing faster receipt or delivery of data. Beginning with 486 processors, two layers of cache are employed. The fastest cache RAM is inside the CPU. It is called L1 cache. The next layer is the L2 cache, which are small SRAM chips on the system board. See at the illustration below:

Increase Hard Disk speed in Windows

If you like to increase/optimize your Hard Disk I/O - read/write speed without buying expensive software utilities to do that job or changing the HD, just follow next steps. With doing these steps you will increase Hard disk speed (depends of manufacture and specification, but its worth to try). The most speed improvement is visible with IDE drives; however there are reports that this tweak also does good for SCSI disks. In any case, it won't harm your system, so try it yourself and let me know what you find! Steps: Run SYSEDIT.EXE from the start & then Run command. Expand the system.ini file window. Scroll down almost to the end of the file untill you find a line called [386enh]. Press Enter to make one blank line, and in that line type Irq14=4096 (note: This line IS CASE SENSITIVE) Click on the File menu, then choose Save. Close SYSEDIT and reboot your computer. Restart windows! The speed improvement will be noticed just after the system reboots, any system info. software can...
