In short, I’m turning some Intel components into budget gaming rigs. It was a challenging process before I started this project, but this weekend has been quite stressful. I built two systems using second-generation Intel chips on DH77EB boards. While it’s becoming harder to find older parts, I managed to get four 4GB SK Hynix HMT351U6BFR8C-H9 replacements today. However, there’s a catch—one of these isn’t quite right. The green labels match the correct part number, but the red ones show an incorrect version labeled ‘U6CFR8C’ instead of the intended ‘U6BFR8C’. This suggests a factory error, reminding me to double-check parts before installation. I’m also curious about the difference between these numbers and how they affect compatibility and stability. I was already frustrated because my power supplies took too long to arrive (after two days), which made me hesitate when choosing between 650W and 450W for future upgrades—despite the $15 price difference. Now the PSUs are still delayed, and I’m facing this new issue. Do you know what the ‘B’ versus ‘C’ stands for here? I’ve attached a comparison of the two part numbers, noting potential problems. Again, these DH77EB boards with second-gen Intel chips.

Also, it seems the main distinction is that the "C" model reaches 1866 at Cl13 latency, while the "B" model lags by .175v compared to the "C". In short, very similar performance, just the "C" version is newer with improved chips.

Considering past RAM problems, I’d prefer to stay with the QVL unless you share details about its updates or revisions. Edited October 31, 2022 by An0maly_76 Updated further

Come back and locate a different vendor. It’s probable that the person who removed the old servers and replaced the RAM created labels using the initial server as a reference, assuming uniformity across them.

Compare the MT16JTF51264AZ chip from Micron Technology with its counterpart from Micron itself.
