Is employing four 4DIMMS units paired with an Intel 285K processor detrimental?
Is employing four 4DIMMS units paired with an Intel 285K processor detrimental?
I have the Intel 285K CPU and the Gigabyte Z890 Aorus Master board.
I understand that Intel's IMC is superior to AMD's in many aspects. Will I encounter similar issues as AMD users when using 4 DIMMs?
I installed four 24GB Patriots chips, each at 8000MHz with CL36 1.4V.
Initially, I planned to activate Intel 200S boost to overclock the whole system while preserving the warranty—this is why I purchased the 8000 kits at 1.4v, as this is the highest boost allowed by the 200s feature. The low latency was a nice extra.
What are your thoughts?
What practical situation would require such a large amount of RAM at high speed? I’m currently running multiple systems—four 24GB Patriots with 8000MHz and a CL36 at 1.4V—to test how well the system handles memory pressure.
Focusing on the goal. It would be interesting to see the results after you give it a try.
No specific use case was provided. The focus is on ensuring all four RAM slots are populated and understanding the implications of purchasing RAM at a discounted price. It’s also about considering potential future resale value and passing the system to a business partner. Concerns were raised about stress on the IMC and compatibility with high-end motherboards supporting higher speeds. The question also asks whether a standard MEMTEST is sufficient to confirm success.
The specifications for the 285K on CPU World indicate it supports DDR5-6400, making it feasible to install four DIMMs at 8000MT/s.

Start by booting the system using the JEDEC default settings for RAM (no XMP), then install Windows. Gradually increase the speed to 8000MT/s, applying XMP as needed, and use MemTest86 once you surpass 6400MT/s.
Also, consider purchasing a single set of four compatible DIMMs rather than two separate pairs. Mixing them during installation could cause instability at higher speeds. Label each pair clearly when they arrive, as minor differences might reduce the overclock potential by about 200MT/s.
I was planning to order a 2 x 24GB kit at 8000MHz and 1.4V, but it's tough to find good prices. When I found one, I thought about getting two kits and seeing if they'd work together. In the worst case, I might install them elsewhere. I didn't realize they sell a 4-pack!
285K operates in dual channel mode, not quad channel.
It's a single unit, correct? Not four identical parts?
To meet specifications, all RAM must come from one matching kit.
A 2 x 48gb package should have cost half of what you paid.
But... if your goal was just for appearance then it's fine.
It's not just one kit. I placed an order for two of these (please see the link!): https://amzn.to/3GIXPPY
What exactly is being referred to as a dual channel CPU? I assumed it was a quad channel IMC.
I was searching for an 8000 kit with precise timings that could operate at 1.4V for Intel 200S boost, and this seemed like a clear choice. The others were significantly more costly.
The document lists 285K specifications and mentions a maximum of 2 memory channels.
As noted, you're exposing yourself to potential problems with two 2x24gb kits. Even if they belong to the same batch, they are made from different silicon. There are three possible outcomes:
1. They function properly without issues.
2. They operate but might struggle to reach their rated speeds, leading to instability.
3. They fail to work together.
It's a bit uncertain. I'd prefer a 4x kit or a 2x kit with higher capacity.
