VCool v1.8 Beta 5!

Published by

This little utility will cool your Athlon/Duron processor on Via KT133 or KX133(A) (VT8363, VT8361, VT82C691/693A/694 or VT8371 +VT82C686x) chipsets during idle!! :D

What's new

Fixed a bug with the PCI options settings.

Added Halt Command Detect option for KT266 boards.

Increased the beep threads priotity to make the beeps occur even when the CPU is VERY busy.

Added L1 and L2 registry settings (HKCU/Software/MPET/VCOOL) to allow tweaking of the "smart" idle loop:

L1 - period of non-C2 idle time after that the CPU enters C2 L2 - if the C2 sleeping time is shorter than L2 when the CPU wakes up, fall back to non-C2 idle.

So basically increasing L1 and L2 (default: 400, 1000) will reduce the cooling effect but increase performance and vice versa. These settings are only active when the "smart" idle loop is activated. Please let me know what settings are optimal on your system.

You can now divide the fan rpms by modifying the FD1, FD2 and FD3 registry entries (default=1). Note: This does not change the internal hardware divisor of the chip, i.e. it won't help if you're having problems with the readout - it'll just devide the calculated rpm by FDx.
