    Question Identical laptops, but one has 3x slower CPU performance?

    We have two G74SX laptops here. One has CPU cores that speed up as needed under load. The other has CPU cores that are stuck at 800 MHz, regardless of load. CPU and GPU are both showing low temp readings. This behavior is the same regardless of operating system, swapping batteries, swapping...

    Question Identical laptops, but one has 3x slower CPU performance?

    Okay, found that this is a widely-known issue with these (and many other) gaming laptops. ThrottleStop fixes it, by turning off the BD PROCHOT flag. After that, benchmarks match the other (identical) laptop. Now the question remains: Why has this BD PROCHOT issue never surfaced in the other...

    Question Identical laptops, but one has 3x slower CPU performance?

    Running CPU-Z's Stress CPU feature on both, and watching both with CPUID HWMonitor, I'm seeing the core voltage of the slow one never getting above 0.77 V per core, while the fast one goes up to 1.21 under load. CPU wattage grows, but never gets above 9 W for the slow one. Fast one climbs to...

    Question Identical laptops, but one has 3x slower CPU performance?

    Also, googling for "799.26 MHz" is returning nothing. This seems to be some kind of magic number for this CPU (the slow one has all cores pegged there, and the fast one has a core or two pegged there when not much is running).

    Question Identical laptops, but one has 3x slower CPU performance?

    We buy out-dated "monster" gaming laptops used, and have good luck with them for running lower-end games, like LOL. We had particularly good luck with an ASUS ROG G74SX that we bought a few years ago, so we just got another identical one (ironically, the market price on this machine has gone up...
