Anyone who has been following me and my tests on igorslab.de for a while knows that whenever there is a new RAM IC on the market, I have to have it and test it immediately! After SK Hynix and Micron in particular have recently launched new memory chips on the market, Samsung is now following suit.
Background and unboxing
The 16 Gbit B-Die, which was already available at the launch of DDR5 together with Intel Alder Lake, was not bad for its time and could be moved to similar clock rates as SK Hynix 16 Gbit M-Die, only with somewhat looser timings and occasional moody instabilities.
Since then it has been pretty quiet in the Samsung DDR5 product range. There was the 16 Gbit D-Die successor sometime in 2023, if you searched long and hard on Asian trading platforms like Taobao, but this die never really made it to Europe. I had actually bought a D-Die set like this, but unfortunately the retailer had sent me the wrong B-Dies at the time and I didn’t want to deal with an exchange/return shipment to China.
Another year later, the next DDR5 die from Samsung was recently spotted in Internet forums, even in this country and installed in Corsair Vengeance DDR5 kits. When a RAM giant like Corsair installs the ICs, then a test is of course doubly interesting: firstly because the ICs can’t be complete duds and secondly because sooner or later potential buyers will be looking for tests. So, let’s test.
As this is a Corsair Vengeance DDR5 kit and we’ve already covered the design and construction in enough detail in other tests, we’ll skip this part today. Instead, we’ll look at the inner workings of the modules and, of course, the overclocking potential. By the way, I bought the kit myself from the longest South American river.
Even though it’s actually just another Corsair Vengeance DDR5 kit, some information about the kit is important. The product number of the kit is CMK36GX5M2B6000C38 and behind it is of course a 32 GB kit consisting of 2 modules with an XMP profile of DDR5-6000 with tCL 38. This relatively loose combination of clock rate and timings is apparently the niche where Corsair has recently installed the new ICs. However, as is so often the case, there is no guarantee as to which ICs you will actually get.
Only when you hold the kit in your hand and look through the window on the back of the packaging do you see the “Version Number”, which has long been used to identify the memory components in Corsair RAM kits – “4.43.19”. 4 stands for Samsung, 43 for 16 Gbit ICs and 19 for the 19th letter in the alphabet, i.e. S. So we have a DDR5 kit with Samsung 16 Gbit S-Die.
It is also interesting to note that Corsair has changed the concept of their serial number. While there used to be an individual sequence of letters and numbers, the kit now has a serial number and the modules are then given a -1 or -2 suffix. A80WT404000MBD is therefore the serial number of our test kit.
Of course, we also find the XMP profile on the sticker again, this time with all primary timings tCL 38, tRCD 44, tRP 44, tRAS 96 at 6000 MT/s or Mbps clock and 1.35 V VDD and VDDQ voltage. The rest of the kit’s structure, including the single-sided assembly, is the same as previous Vengeance DDR5 modules.
