CPU Priority and IRQ Tweak

Post by Sandells »

taken from axcel216's:<br><br>REAL TIME PRIORITY<br><br><br>... Appears courtesy of Hesham (hesham732@cs.com).<br>NOTE: To learn how to increase the level of CPU priority used for foreground/background applications in Win9x/2000/ME see "CPU PRIORITY", also in REGISTRY.TXT, part of my Win9x/2000/ME/XP + DOS 7/8 ©Tricks + Secrets files [W95-11D.ZIP].<br><br>"To boost dramatically your CPU priority in Windows 9x/ME for higher performance, run Regedit and go to:<br><br>HKEY_LOCAL_MACHINE\System\CurrentControlSet\control\PriorityControl<br><br>Create the "PriorityControl" Registry subkey if not present: right-click in the left hand pane -> select New -> Key. Name this new subkey "PriorityControl" (no quotes) -> click OK or press Enter.<br>Highlight this new subkey -> create a new DWORD Value called "IRQ#Priority": right-click in the right hand pane -> -> create a New DWORD Value named "IRQ#Priority" -> click OK -> double-click on it -> check the Decimal box -> type 1 to turn it on -> click OK or press Enter.<br>To get the actual IRQ# go to: Control Panel -> System -> Device Manager -> System Devices -> System CMOS/real time clock -> Properties -> Resources tab -> default IRQ# is 8 on all IBM PC clones [yours included <!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/im ... /smile.gif ALT=":)"><!--EZCODE EMOTICON END--> ]. Therefore you need to rename the DWORD above to read "IRQ8Priority" (no quotes).<br>Close Regedit and restart Windows to see the effect.<br>I have applied this trick to Win95 and WinME, both with great results."<br><br><br>Hope this is useful <!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/im ... /smile.gif ALT=":)"><!--EZCODE EMOTICON END--> <!--EZCODE EMOTICON START :eek --><img src=http://www.ezboard.com/intl/aenglish/im ... ns/eek.gif ALT=":eek"><!--EZCODE EMOTICON END--> <!--EZCODE EMOTICON START :rollin --><img src=http://www.ezboard.com/intl/aenglish/im ... s/roll.gif ALT=":rollin"><!--EZCODE EMOTICON END--> <br><br>Steve <p></p><i></i>

Well, I tried this and it hasn't crashed my system so far.<br><br>Haven't had enough time to evaluate the performance gains yet, but doesn't seem to be hurting things at least. Will let you know... <p></p><i></i>
