What's the difference between TFRC and TRC? (AMD versus Intel in the 5th generation timing)
What's the difference between TFRC and TRC? (AMD versus Intel in the 5th generation timing)
At 2666MHz none of them would drop further; the device I think is a CJR appears only as Kingston DRAM in CPU-Z, whereas the G.SKILL kit shows Samsung, which is interesting since my other HyperX 3699MH CL17-19-19-39 is clearly listed under SK Hynix in CPU-Z.
Samsung E-Die behaves like Hynix CJR; however, a lower-tier B-Die still outperforms it in low-frequency scenarios.
those aren't Intel AMD components; they're different clock speeds. Intel still offers TRC and TRCF options (typically 240, 280, or 320 depending on memory), and the TRC is just the sum of the third and fourth timing settings. Regarding Ryzen, it appears to handle 1T more smoothly than Intel TLC. I thought the 16-19-19 models were problematic, but I wasn't sure about the 14-14-14—maybe they're not standard, as those often result in 16-16-16, which seems to be CJRs.
This appears to be a setup from two distinct PCs or one with dual bays. The left side shows a Hynix CJR chip, while the right side has an unspecified Samsung component. It seems unclear which exact chip it is, though the B-Die appearance suggests a B-series part.
Same PC on both Intel systems, but the setup differs: my system has 4x8GB while yours uses 2x16GB. The ASRock boards are terrible—they only support slots 1 and 3 up to 3066MHz, which is way below what you need. I upgraded to a higher capacity model because they likely can reach 3600MHz or more. XD
The issue lies in combining various chips, as the least powerful one sets the limit. With a CJR chip, you can't drop below CL13 at 2666Mhz. Since you have four sticks, verify the performance of the others.
They mentioned a single stick of GSkill or possibly others, but it wasn't clearly B-Die because details aren't confirmed. The exact chip remains uncertain.
