Default Vengeance 64GB (32GBx2) SoDIMM Number of Ranks

I am trying to find out how many memory ranks (single or dual) each piece of Vengeance 64GB (32GBx2) SoDIMM has (part number CMSX64GX4M2A2666C18). Not having any luck so far. Does anyone know?

Pretty sure those have to dual rank, since there is no higher density chips available to build them in single rank (that would require 32gbit ICs).

Many thanks. So you think may be dual rank and 8 banks (2RX8) similar to the Crucial 32GB SODIMM?

2Rx8, yes. They might use a different kind of 16Gbit IC, though. There are other options than Micron for that from Hynix and Samsung.

Thanks emissary42. Is there any way of knowing who the OEM is for the 16Gbit IC?

The credit goes to "Idwilliams" for his post. If you bought the ram you can use Thaiphoon Burner to read the ram as well.

in it it states the following

Corsair
"Version Number"

Corsair sticks identify the IC with a 'version number' on the label such as "ver 4.31" - props to them for this as it helps even less knowledgeable users to match kits when adding more sticks retroactively. The DDR4 numbers aren't officially documented, but they follow the same pattern as DDR3.

The numbers take the for "ver X.YZ" where;
* X is IC maker - 3 for Micron, 4 for Samsung, 5 for Hynix, presumably 8 for Nanya as with DDR3
* Y seems to be capacity per rank - 1 for 2GB, 2 for 4GB, 3 for 8GB. Usually this translates directly to IC density (8GB/rank = 8Gbit), but ver 4.14 which uses half as many double width "x16" 4Gbit chips is a special case.
* Z is revision, usually starting from A=0 and usually counting up one letter per increment. Hynix's first revisions are lettered "M" which is numbered as X.Y9, samsung now do this too and it will proesumably be the same.

The known and possible version numbers are as follows;
Version Vendor IC Confirmation?
3.20 Micron 4Gbit Rev.A Presumed
3.21 Micron 4Gbit Rev.B Confirmed
3.22 Micron 4Gbit Rev.E* Speculated
3.22 Micron 4Gbit Rev.F* Confirmed
3.31 Micron 8Gbit Rev.B Confirmed
3.33 Micron 8Gbit Rev.D Presumed
3.34 Micron 8Gbit Rev.E Speculated
4.14 Samsung 4Gbit D-die (4x16) Confirmed
4.23 Samsung 4Gbit D-die Confirmed
4.24 Samsung 4Gbit E-die Confirmed
4.31 Samsung 8Gbit B-die Confirmed
4.49 Samsung 16Gbit M-die Speculated
4.40 Samsung 16Gbit A-die Speculated
5.29 Hynix 4Gbit MFR Confirmed
5.20 Hynix 4Gbit AFR Confirmed
5.21 Hynix 4Gbit BJR Speculated
5.39 Hynix 8Gbit MFR Confirmed
5.30 Hynix 8Gbit AFR Presumed
5.31 Hynix 8Gbit "BFR"??? Speculated
5.32 Hynix 8Gbit CJR Presumed
8.20** Nanya 4Gbit Rev.A Speculated
8.30** Nanya 8Gbit Rev.A Speculated

*Rev.F is confirmed to come in ver3.22 sticks, but that doesn't leave a gap for Rev.E. It's wildly guessed that they may both appear under 3.22.
**It's unknown if Corsair even use Nanya for DDR4 but the version number it would likely be if they did is included for completeness

Thanks, KILLER_K and Idwilliams. I am waiting for the sodimm to be delivered and will check the version number when it does.

Checking the version number is the easiest way to go about it. If you want to confirm it, you don't need to buy TB, that is already possible with the free demo.

Not sure I understand. How do I go about getting a free demo?

emissary42, thought I told you to buy Thaiphoon Burner Pro. When I said if you bought your ram that you could use Thaiphoon burner to read it. He took it out of context. There is a free version of Thaiphoon Burner as well as a paid version.

Thaiphoon Burner Free version:

EDIT: Corrected my post to make sure everyone knew I was talking about him buying the ram and not the program.
