Windows limits itself to a single memory channel.
Windows limits itself to a single memory channel.
Combining mixed sticks in a single channel doesn't ensure compatibility with dual channel. Intel emphasizes the necessity of matching MHz and latency. Exceptions may exist, but reliability isn't assured.
Ensure it's single channel by running cb in its current state with all sticks inserted. Remove every stick except one and check if the score changes. If triple channel activates, the score should be nuked; otherwise, it likely won't shift much or at all. Good thing uncore runs slowly—try 3600MHz (~1.37v) or 3800-3900MHz (1.4-1.45v) with VTT/QPI for better performance. Rams are also slow, but mismatches may not trigger significant clock changes.
It might be that a CPU pin has shifted slightly, affecting the Z77 OCF. This issue could be resolved by adjusting the pin position carefully. Be sure to inspect the socket pins—there may be one that’s slightly off or misaligned. If you notice it, realign it and keep track of which pin is affected, as this could happen again if you swap chips instead of replacing them.
It's amusing because I had to adjust a few pins to make it function properly. I'll look into who or what caused the issue.
