- This program calculates and sets the optimum memory refresh rate for your
- machine. It will then create a short .COM file that you can run to quickly
- set the refresh rate. The memory refresh concept is from an article by
- Brian Roemmele in the 7/88 issue of PC Magazine. The .COM file produced
- is the same as the QFRESH.COM program from that article. Please see that
- article for a thorough discussion of memory refresh rates.
-
- NOTE: It is possible that your machine will 'hang' before the point
- CalcQF considers optimum is reached. This will not harm your
- machine but you will have to re-boot.
-
- Switches:
-
- /C - Calculate the optimum memory refresh rate. /I, /O and /T imply /C
- /I - change the default Increment rate of 16. In general, larger values
- will produce numerically higher optimum rates and smaller values
- will produce lower ones
- /O - don't estimate the Original refresh rate.
- /T - set the Tolerance. The default value is 0.00001. This determines what
- rate CalcQF considers optimum. Larger values (i.e. 0.01) should produce
- numerically lower optimum rates and smaller values (i.e. 0.000001)
- should produce higher ones.
- /S - Skip the calculation phase and go straight to file creation.
-
- Do not press any keys while this program is running as this can affect
- the calculations. Some TSRs and device drivers may also affect them.
- Because of this you may want (or need) to run CalcQF with nothing loaded
- into memory. The rate referred to as the original rate is the refresh
- rate in effect when CalcQF was started. The rate CalcQF says is the best
- rate is really only an approximation but it should be close to the best rate
- for any given application. At the very least it will provide you a good
- starting point for further experimenting.
