What is the difference between ver 4.31, 5.32, 5.39?
 
What is the difference between ver 4.31, 5.32, 5.39 etc.. on DDR4 memory?
Thanks,

The version number states which IC type is used on that specific piece. According to the Corsair version scheme, that was implemented sometime during the DDR3 days:

Ver4.31 = Samsung 8GBit B-Die
Ver5.32 = Hynix 8Gbit CFR (they are probably either AFR or MFR, though)
Ver5.39 = Hynix 8GBit MFR

Thanks for the replay. What do the abbreviations stand for, CFR, AFR, MFR?

So what is the actual difference between the versions besides which manufacture memory chips were used? isnt 5.39 newer than 5.32 and 4.31? Is one version fast or slower then the others? I assume MFR means manufacture? what do the other abbreviations mean? Thanks.

Hynix uses AFR, BFR etc do differentiate between their die revisions. Is is similar to A-die, B-die etc, just another nomenclature. The Corsair version does not state which is newer or older, like is said it just identifies the DRAM IC type used on the kit.

There is no slower or faster at XMP settings, apart from maybe the number of memory ranks that goes back to IC density, but each IC type has its own properties so undervolting or overclocking potential and platform compatibility can differ between versions.

What about Ver5.30?

Hynix 8Gbit AFR

The Samsung 8Gbit is really the best for oc huh? I'll have to try it myself

Hynix has never used such a nomenclature. It uses definition like A-die, B-die, C-die, and so on. You can check it out by yourself googling with "site:skhynix.com c-die ddr4 8gb".

Are you new to memory?

I don't need to google anything, you can just check the original IC types names yourself (in x8 retail configuration):

H5AN4G8NAFR or just 4Gb(it) AFR
H5AN8G8NMFR or just 8Gb(it) MFR
H5AN8G8NAFR or just 8Gb(it) AFR

The shortened descriptor is commonly used intern, by press and enthusiasts instead of the full IC type for many years, even back in the DDR3 days; esp for 2Gbit BFR/CFR and 4Gbit MFR (like here or here). The older datasheets did not even have the "M-die" type of naming anywhere in them, just the full IC name.

Hynix does NOT use definitions like MFR, AFR, etc for distinguishing Die Generation. The only one letter is defined for it, C-die, B-die, A-die, etc. The letters F and R do not provide information on Die Generation. I suggested you to check this out with google, but you seem to be smarter than I expected. OK, below you can find the download links to the module datasheets where is what I am talking about.

C-die https://www.skhynix.com/product/file...ad.do?seq=7742
A-die https://www.skhynix.com/product/file...ad.do?seq=7654
M-die https://www.skhynix.com/product/file...ad.do?seq=7088

I don't know if this helps or hinders but I found it on my searches

https://www.reddit.com/r/overclocking/wiki/ram/ddr4

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

Hi

Can anyone confirm what is ver 4.32?

I've seen a lot kit 2x16gb 3200mhz c16 that has version 4.32. I believe it has been manufactured April this year but there is zero reference if it's actually b-die or not

Cheers

I have a 4.32 kit. SPD says it's b-die on my modules but I don't think that's accurate or there is something else to it. When using Dram Calculator for Ryzen it seems to align more with settings generated by "Samsung OEM" but I don't really know what that means.

Hi all, sorry for bringing up this old thread, however, I'm facing some issues on my MSI B450 Gaming Plus with Ryzen 2600X. Previously, when I upgraded my PC I got the corsair ver 5.32 (2 x 8GB) which I was fortunate to set it to 3200mhz. With the recent, reduction of RAM prices, I got another 2 pcs and it came as ver 4.32.
I was then faced with issues not being able to boot up to 3200mhz. The furthest I've got was to set it as 3063Mhz (windows 10 without BSOD).
Any advise how to go about achieving to 3200mhz without any further tweaking? If I were to return the ver 4.32 to Amazon, is there a way to order v5.32 so that it'll work?

Thanks!
