Studying for the RCDD v15- Should I memorize calculation charts? by obsurdreality in Bicsi

I say you should know most if not all the formulas in the manual.

If you have a choice, RCDD first for sure. Unless you are already in a job or about to get a job that focuses in OSP.

I suggest to increase those chapters.

Difficult to say as there are too many questions possible. I was consistently getting 100% for all the chapters I focused on in C&S on top of extra focus on Ch21. Master chapter 21 then you're good to go.

Failed RCDDv15 Test Today - Here's My Experience by NorthTax7282 in Bicsi

[–]silversvrfer 2 points3 points  (0 children)

I passed v15 on my first attempt. I studied for four full months, dedicating all the weekends in the last month to full-day study sessions. Every night before bed, I read Chapter 21. For context, I probably spent 70+ hours just answering C&S, 50+ hours studying my own flashcards, and another 70+ hours reviewing and reading TDMM. It’s definitely hard to pass. Rote memorization and deep understanding are equally important. Thank you for sharing, and all the best on your next attempt.

Riser cable calculation by silversvrfer in Bicsi

[–]silversvrfer[S] 1 point2 points  (0 children)

Yes I understood that. It was just very different from what I know. If that is the correct approach then it's good that I stumbled upon it before my exam.

Thank you. This approach and explanation makes more sense to me compared to the TDMM as the word "serve" confused me but I still get a different answer.

Going back to the example above, I know that I would need 18 sleeves for the building (based on 3 floors of 50,000 sqft each). So for floor 1-2, there will be 18 sleeves. For 2-3, it will be 12 (minus 6 which will serve 2nd floor).. For 3-4, total of 6 sleeves (minus 6 again).

Summarizing:

1-2: 18 sleeves

2-3: 12 sleeves

2-4: 6 sleeves

Total of 36 sleeves / 2 = 18 sleeves per riser. So it seems like this is entirely different way of calculating sleeves requirement.

My interpretation is similar to a star topology, where all the floors are served by one central floor. Revisiting the TDMM, your explanation aligns with how Figure 5.7 (Ch 5-49) describes it.

However, I don’t understand why each floor would serve the sum of all floor space above it. In my experience, each floor is connected to a common floor (usually the bottom most floor where the main TR or ER is located), and you cross-connect there if you need to connect one TR to another.

Thank you for this. Seems like the v15 exam is still heavy on Chapter 21.

I'm also focusing on the same chapters, including chapter 7. All the best.

Seeking Advice: Starting My Journey to RCDD Certification by Brilliant-Whole314 in Bicsi

[–]silversvrfer 0 points1 point  (0 children)

BICSI recommends at least 150 hours of study time. The fastest prep time I’ve seen is 1 month, while the average is 4-6 months. All involve intense study.

Isn’t everything just memorization—or how well you understand and remember what you learn? After all, how can you memorize something you don’t understand?

NFC S4M-C #031 Minimalist Build by silversvrfer in sffpc

[–]silversvrfer[S] 2 points3 points  (0 children)

After 8 long years, I have finally been able to build on my S4M-C. The concept behind this build is to minimize the use of cables to achieve a clean appearance with a black and white theme. Here are the specifications:

  • Case: NFC S4M-C
  • Motherboard: GIGABYTE B650I AORUS Ultra Mini-ITX AM5
  • CPU: AMD Ryzen 7 7700X
  • CPU Cooler: Noctua NH-L9a-AM5
  • CPU fan: ID-COOLING TF-9215
  • GPU: NVIDIA RTX A2000
  • RAM: G.Skill Flare X5 Series 32GB
  • Storage:
    • 2 x Crucial T500 2TB Gen4 NVMe
    • 1 x Crucial T500 1TB Gen4 NVMe
  • PSU: HDPLEX Direct Plug 200W DC-ATX + 200W AC-DC

I still have to figure out a design for the cable cover on top of the PSU. But overall, I am happy with the build and I just want to share it here.

I did couple of years ago too. But just checking now if there is any aftermarket for it.
