I have to concede. You are right! 5.39 would not be Samsung. Sorry for the confusion I might have created. I apologize. Yes I have CMK16GX4M2B3200C16 but upon closer inspection of the sticker, mine is actually v4.31. OP was asking for v5.39 and I ignorantly assumed these were all the same. I see from another thread someone asked about the version numbers. 5.39 is Hynix. :( Ver4.31 = Samsung 8GBit B-Die <---- This is what I have. Ver5.32 = Hynix 8Gbit CFR (they are probably either AFR or MFR, though) Ver5.39 = Hynix 8GBit MFR

I am not sure about luck getting Samsung B-Die. They seemed to have 2 different 3200 Vengeance LPX part numbers. The first 2 kits I bought were the same part number for the store and both were stamped the same from Corsair. They both turned out to be Hynix. Then I was returning the RAM and noticed they had another box there. Same product at the store level but the number on the stick was CMK16GX4M2B3200C16 5.39. I looked at two kits in the pile with this part number from this thread. Both kits tested as Samsung B-Die using Typhoon burner. Now some months later I see they now sell an AMD kit. They are samsung B-Die. I see what you did there Corsair. The AMD kit is now $20 more. The regular kit is Hynix. You just need to know which kit is which. C.

I have 2 sticks of CMK16GX4M2B3200C16 and by the way... they are verified Samsung B-Die. Since the last few BIOS updates on my MSI X370 Gaming Pro Carbon motherboard, they have ran at 3200 CAS 16 simply using XMP profile #2 in the BIOS. But a number of months ago they would only do 2933 stable which was XMP Option #1 in my BIOS. But now... #2 XMP option works no problem. Rock solid and verified stable with memtest86 and several hours of AIDA64. In fact... Now on my same board with Ryzen 5 2600X I get 3200 14 14 14 34 timings stable. On MSI boards in the BIOS, they have a list of frequency and timings you can TRY and that one also works. So I can run that or 16 18 18 36 no problem. CAS 14 settings is faster a bit but so far only in RAM benchmarks. Not in anything else. UPDATE - I apologize. Yes I have CMK16GX4M2B3200C16 but upon closer inspection of the sticker, mine is v4.31.
