If it doesn't function, it's expected when it isn't working in dual mode.
This approach would essentially create a dual-channel setup using sticks from each pair in the specified modes. It could improve stability by ensuring symmetry between the two channels.
I believe the arrangement is reversed. 1 and 2 belong to channel A, while 3 and 4 are in channel B. Typically, using two sticks, one goes into channel A and the other into channel B. When you switch to two distinct kits and assign one pair to channels 1-2 and another to 3-4, each channel ends up with a single RAM type and a matching set of timings. This guarantees compatibility. In your situation, because both kits have the same capacity, this setup seems optimal. I’ll share some insights from my experience, though it might not fit your configuration exactly. Previously, I used an Asus Z97A with 16GB (4x4GB) DDR3 2133 9-11-10-28 1.65V. I planned to boost capacity and bought a 24GB kit, replacing two 4GB sticks. I selected RAM with similar specifications available, such as 2133 10-12-12-31 1.6V. I tried various methods for installing the RAM. Blue indicates 8GB module, Green denotes 4GB module. | In this arrangement, my motherboard detected XMP settings from the lower latency 4GB sticks and applied them to all RAM. It was unstable because the 8GB sticks couldn’t run at 9-11-10-28. || | In another setup, the board handled different timings per channel: the 8GB sticks in channel A ran at 10-12-12-31 while the 4GB sticks in channel B operated at 9-11-10-28. This was stable, though I had only 16GB of dual-channel memory plus another 8GB in single-channel mode. | | In a third case, the board read XMP from higher latency 8GB modules and set those settings for all RAM. It performed exceptionally well. With 24GB dual-channel memory (12GB each), timings set to 10-12-12-31, it functioned flawlessly for several years.
Running in 1-2, 3-4 gives each channel its own setup, which improves stability. However, this means it doesn’t use dual channel mode. This approach works better with asynchronous RAM if timing issues arise. In your examples, splitting the RAM evenly between channels was the most practical solution.
Only when the RAM has varying capacities will it operate either single-channel or mixed. When mixed, Windows will prioritize dual-channel memory first. If every RAM module shares the same capacity, it will function in dual-channel mode. Yes! Since my RAM had comparable timings, it managed to run successfully. If this is the case, proceed as planned.
