I don't disagree one bit. If ANYTHING changes on the RAM, so should the model number, but it doesn't. For example, Thaiphoon Burner says my Corsair RAM has Samsung B-Die, which is rumored to be the holy grail of chips for AMD systems, but I can tell you the "B-Die" set I mentioned above is much less stable, more finicky, less likely to OC well, and actually slower than the SP "Value" RAM, which was kind of my point.

I also have another set of Corsair Vengeance LPX PC3000(CMK16GX4M2C3000C15S) that is reported as Hynix C-Die, that is also more sable at XMP than the "B-Die"...and that kit randomly comes with B-Die as well, but not mine.

So, even the "B-Die" holy grail ram is not always best. It seems completely random what works and at what settings and XMP is barely a "rough guide" for where to set it, and the QVL list? Can't say I have EVER found the specific RAM on the lists to be available at all, and if it was, it was 4x the cost of the next RAM or in some configuration I didn't want. Single instead of pairs, etc.]]> Thu, 22 Jun 2023 20:16:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=25971&PID=105297&title=a-memory-compatibility-report-b450-b550#105297 https://forum.asrock.com/forum_posts.asp?TID=25971&PID=105289&title=a-memory-compatibility-report-b450-b550#105289 Author: threadzipper1957

The info is nice, but as long as companies are assemblers rather than manufacturers, any kind of QVL is useless
Corsair is an assembler, wo buys PCB's and chips, from maufacturers like Elpida, nanya, Spectek, Hynix, Micron, Samsung and others, and as long as the Primary timings, speed and voltage stay the same, they keep re-using the same partnumber, over and over again.
I have a number of people, who bought 2 kits from Corsair, and Kingston, and it truend out, one kit used Micron chips, the other had hynix, and what is also possible, is that they have one kit with 2GB chips from brand A, and the next batch, contains 4GB chips from another brand.
That is why there are so many problems with memory.
XMP is overclocking for beginners (wouldn't want to say Dummies) it is supposed to work, on every existing combination of CPU (the memory controller after all, is integrated in the CPU), chipset, and motherboard, it is not optimal by far, and is not guaranteed to work.
What's the point of a QVL, when the rest is a silicon lottery

Hope this is useful to someone eyeballing any of the following for purchase.
The two boards/cpus I have used both with. Both boards behave the same with each RAM type:

ASRock B450 Fatality Gaming K4 (BIOS 5.60) / Ryzen 5 2600
ASRock B550 PRO4 (BIOS 2.71) / Ryzen 5 5600

Silicon Power Value Gaming (model: SP016GXLZU320BDAJ5)
Runs perfectly, not picky, very pleased with it.
XMP says: 3200MHz 16-18-18-38 62 1.35v ***stable
I ran at: 3200MHz 16-18-18-38 58 1.34v ***stable

Corsair Vengeance LPX (model: CMK16GX4M2B3200C16R)
A little picky about timing and NOT an overclocker.
XMP says: 3200MHz 16-18-18-36 tRC 54 1.35v ***unstable
I ran at: 3200MHz 16-18-18-36 tRC 58 1.35v ***stable

Thaiphoon Burner (not sure if accurate) shows Samsung B-die on the Corsair and Samsung unknown-die on the SP. In AIDA64 tests, the cheaper Silicon Power RAM beats the "more premium" Corsair by a little in tests done on the B450/Ryzen 5-2600 board:
