I know that there used to be a Corsair memory detection tool, but I can no longer find it. I didn't find anything when searching Google.

I would like to scan my machine to know a few things:

  1. How many memory slots I have on my motherboard.
  2. The stats per memory stick I have installed in my machine (i.e. speed and size of each stick)
  3. The maximum allowable size and speed per slot (i.e. my motherboard can manage 4GB per slot, at DDR27600 - if that is even a speed, been a while since I upgraded :|)

I am using Windows XP and 7. Any suggestions?

+1 Actually shows information about available RAM slots unlike some options below. –  User1 Feb 5 '13 at 23:59

How about going by command-line without any third party installer?

wmic MEMORYCHIP get banklabel, capacity, caption, devicelocator, partnumber

gives you something like this

BankLabel  Capacity    Caption          DeviceLocator   PartNumber
BANK 2     4294967296  Physical Memory  ChannelB-DIMM0  xxxxxxxxxx-PB

Cool! Can this tool list also the memory slots that are not used? –  Jindra Helcl Apr 15 at 8:33

For more memory info type first just wmic -> that will open wmic console, and afterwards type memorychip which will print all memory info in one big scrollable line. –  klerik May 13 at 9:34

CPU-Z offers detailed information about RAM slots, timings, XMP profiles, etc. As for max supported you normally will have to look up the limits imposed by your northbridge.

CPU-z really is the best out there, and it will suite your needs wonderfully. –  wizlog Sep 2 '11 at 22:52
    
How can I tell how many slots there are, and how many are in use? –  Martijn Mar 4 '13 at 10:12

The SPD tab shows individual slot details. –  Lunatik Aug 14 '13 at 10:17

I'd use HWiNFO for the task. Why? It's free, it's small, there is a portable version. Also, it shows a lot more if you want to.

-1 I didn't see information about available RAM slots. –  User1 Feb 5 '13 at 23:59
    
It shows a misleading "Row 0" and "Row 2" suggesting there's at least a Row 1 which would lead 4 slots, but I know there are only two. –  TWiStErRob Dec 11 '14 at 21:01

What about PowerShell, Let's check this out:

Get-WmiObject -Class Win32_PhysicalMemory | fl BankLabel, Capacity, `
  DeviceLocator, PartNumber, SerialNumber, PositionInRow, Speed, Tag

None of the solutions above truly present an accurate description of physical memory configurations including empty slots, particularly with servers running Windows due to the lack of SPD info (which most of the reporting programs freely available rely on). The ONLY solution I have found that does not cost s-tons is Belarc Advisor. It doesn't have a nice real-time interface like Speccy but the text report is mucho helpful. Just look at this, does not get any more clear:

Memory Modules Slot 'DIMM_A1 ' has 16384 MB (serial number 0D561***) Slot 'DIMM_A2 ' is Empty Slot 'DIMM_A3 ' is Empty Slot 'DIMM_A4 ' is Empty Slot 'DIMM_A5 ' is Empty Slot 'DIMM_A6 ' is Empty Slot 'DIMM_B1 ' has 16384 MB (serial number 0D561***) Slot 'DIMM_B2 ' is Empty Slot 'DIMM_B3 ' is Empty Slot 'DIMM_B4 ' is Empty Slot 'DIMM_B5 ' is Empty Slot 'DIMM_B6 ' is Empty
