i5 2500 strong performance around 4GHz frequency
i5 2500 strong performance around 4GHz frequency
I'm testing a MAME and similar emulator setup in a compact cabinet for my dad. I found out the processor speed is off by nearly 300 MHz. It's an H61 board running an i5 2500 non-K (SR00T) with no BCLK tweaks. Despite this, it still claims to run around 4 GHz, which seems unusual since it's a locked chip meant for a base speed of 3.3 GHz with a max turbo of 3.7 GHz. I haven't seen an Intel chip exceed its rated boost without special overclocking, which isn't expected here. Anyone have experienced this before?
Interesting. If it functions properly, perhaps it's best to leave it alone?
I didn't initially consider making that call, but CPUz indicated the clock was around 3.6. I observed it fluctuating and Windows itself seemed to confirm it. I'm planning to try to clarify this as accurately as possible, describing it in terms of a delta from the boost clock versus the base value—like if CPUz showed 3.6 while Windows reported 4.0, or vice versa. It's still intriguing and raises questions about how Windows actually obtains its timing information, though it's not quite as impressive as a fully secured chip operating beyond its limits.
