I would use:
Sub Macro1()
Dim Dict_aaa, R
Dim tStart, tStop, Elapsed, tMin, tSec, msg
tStart = Timer
Set Dict_aaa = CreateObject("Scripting.Dictionary")
For R = 1 To ActiveSheet.UsedRange.Rows.Count
If (ActiveSheet.Cells(R, "A").Value & "X" <> "X") Then
If (Not Dict_aaa.Exists(ActiveSheet.Cells(R, "A").Value)) Then
Dict_aaa.Add ActiveSheet.Cells(R, "A").Value, R
End If
End If
Next R
tStop = Timer
TElapsed = tStop - tStart
tMin = TElapsed \ 60
tSec = TElapsed Mod 60
msg = "Loaded " & Dict_aaa.Count & " unique records from " &
ActiveSheet.UsedRange.Rows.Count
msg = msg & Chr(13) & "in " & tMin & " minutes and " & tSec & " seconds"
MsgBox msg
End Sub
I tested it against 135,564 records, and stored 100,200 unique values in 2
minutes 46 seconds (using Excel 2010)

Subject: $$Excel-Macros$$ Excel 2007...Experiment more than 1,048,576 values in
a 1 dimension array
Hi,
Following a query, I'm trying the code below and I find out that the "aaa"
array
is dimensionned with 1,049,574 as worksheet wsb column 1 hold 1,000 values, but
it doesn't hold values from wsb worksheet. Is there any other way to get all
the
2 columns from 2 different worksheet into a scripting dictionary for processing
unique values?
---
Sub makeData()
Dim wsa As Worksheet
Dim wsb As Worksheet
Dim ra As Range
Dim rb As Range
Dim c As Range
Dim i As Long
Dim cnt As Long
With Application
.ScreenUpdating = False
.Calculation = xlCalculationManual
.DisplayAlerts = False
End With
'ThisWorkbook.Worksheets.Add(after:=Worksheets(Worksheets.Count)).Name = "MSH1"
'ThisWorkbook.Worksheets.Add(after:=Worksheets(Worksheets.Count)).Name = "MSH2"
Set wsa = ThisWorkbook.Worksheets("MSH1")
Set wsb = ThisWorkbook.Worksheets("MSH2")
cnt = wsa.Rows.Count
'Set ra = wsa.Range(wsa.Cells(1, 2), wsa.Cells(Rows.Count, 2))
Set rb = wsb.Range(wsb.Cells(1, 2), wsb.Cells(1000, 2))
i = 0
For Each c In rb
c.Value = i
i = i + 4
Next c
With Application
.ScreenUpdating = True
.Calculation = xlCalculationAutomatic
.DisplayAlerts = True
End With
End Sub
