Multiplier Stuck below max
Multiplier Stuck below max
Even when I adjust the multiplier in BIOS to 41, Windows or W/E won't allow it beyond 39. This is my i5 3550, and I'm attempting to achieve the same overclock as the link provided. Ideas? I have Windows Power Options enabled and I'm using the newest updates in Windows 10 Pro 64 bit.

It seems for a non-K model, you can reach up to 4 Ghz with a multiplier of 39 and a modified base frequency. You might have just missed out in the silicon lottery.
I don’t see any reason why I shouldn’t be able to duplicate the link I shared. I already have it at 4.1ghz. It might be my bios, or perhaps Windows, or possibly both. I set the multiplier to the highest setting, but they all operate at the lowest of the four cores—39...I’m not sure how to adjust that without getting too complicated. I also have the latest bios installed, but I’m not certain what else to try. The person in my link has a different MOBO, so maybe that’s why it works differently for them, but still, I can set the multiplier to 41. When I open Windows and check CPU-Z, it doesn’t exceed 39. I’m still unsure about the reason.
It's due to the VRM overheating. This occurred when switching from air cooling to liquid cooling. Without airflow around the VRM heatsink (which is near the socket), it becomes extremely hot and drops temperature. If you let it cool down and then reapply stress, it may function temporarily until it gets hot again. The fix I discovered was adding a small fan near the VRM heatsink. It now works well, with stable 4.5 GHz performance.
