Question:
I want to put CPU speed on my 'About' Form. Can you help me?

Answer:
I will give you systax for getting CPU Speed.
I think your About Form will looks nice with this.

function GetCPUSpeed: Double;
const
DelayTime = 500;
var
TimerHi, TimerLo: DWORD;
PriorityClass, Priority: Integer;
begin
PriorityClass := GetPriorityClass(GetCurrentProcess);
Priority := GetThreadPriority(GetCurrentThread);
SetPriorityClass(GetCurrentProcess, REALTIME_PRIORITY_CLASS);
SetThreadPriority(GetCurrentThread, THREAD_PRIORITY_TIME_CRITICAL);
Sleep(10);
asm
dw 310Fh
mov TimerLo, eax
mov TimerHi, edx
end;
Sleep(DelayTime);
asm
dw 310Fh
sub eax, TimerLo
sbb edx, TimerHi
mov TimerLo, eax
mov TimerHi, edx
end;
SetThreadPriority(GetCurrentThread, Priority);
SetPriorityClass(GetCurrentProcess, PriorityClass);
Result := TimerLo / (1000 * DelayTime);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
ShowMessage(Format('Your CPU speed: %f MHz', [GetCPUSpeed]));
end;
{Note:
You should call the GetCPUSpeed
function more than
one time to get a good result. }
