Third ram?
Third ram?
You have two 16GB RAM modules and a third of the same size. You wanted three sticks for stability, but the setup caused crashes and blue screens. It’s possible the configuration isn’t ideal or there are compatibility issues.
This setup involves mixing RAM from different packages, which can lead to instability. Are you referring to a system with DDR4 or DDR5? Additionally, using three sticks might force your memory into single-channel mode instead of dual, resulting in reduced performance—still more RAM but slower speeds. I’m not entirely certain about that detail.
The issue involves your 2x16GB system running in dual-channel mode, while the third stick operates on a single channel. This setup may be affected by varying IC chips, memory configurations, speed settings, and timing parameters, leading to crashes, freezes, or BSODs.
Absolutely, certain DIMMs can clash with one another. On typical setups it's usually best not to use three RAM modules at once. Some HEDT CPUs handle triple channel, though this isn't widely used. Generally, the first two sticks will work in dual channel, and the third in single, which can cause a drop in performance after that point. The issue is probably due to different components or design quirks, as @CommanderAlex noted.
Only systems that enable Intel Flex Mode work well with DIMMs of various sizes. My previous experience was in 2011 with a Sandy Bridge processor. I used a 4GB module alongside a 2GB one, both running under Intel Flex Mode. I’m uncertain if this setup is fully supported or compatible with the current platform.
In the meantime I’m able to reach about 80% of the DDR2 WR (1520) p95 large FFTs in a somewhat awkward 1x3 setup. These drives are identical in specs, so it makes sense they function well. Probably just different drivers or software conflicts are at play. The third drive will operate in single channel, while the first two run in dual channel because the first 32GB are split across two channels, and the remaining 16GB use a single channel since there’s no matching drive on the other side. Even with this setup, it can still outperform a slow pagefile if you need more memory.
Maybe the timing settings were applied at JEDEC, but not XMP.
