Unless you are playing a game that has all of your CPU cores running full throttle with no breaks you shouldn't see much of a performance decrease, if any at all.Īlso as an alternate suggestion, how long have you had your laptop? If you've had it a while and you've never given it a good dusting, consider doing so. This will prevent some short performance boosts but should also prevent temperature spikes from said boosts.Īnd as was mentioned before, you can lower either your reference clocks or your multipliers to lower the clock speed of your card to lower temperatures. To avoid larger spikes in temperatures, consider turning off Turnbo Boost Short Power Max Enable, or lowering the wattage of it. When you hit an instability just revert your voltage to a previously stable value. Offset your core voltage by -5mV incrementally and test for stability. I have seen elsewhere that people with an i7-4720HQ have gotten anywhere from -60mV to -100mV on their undervolting while remaining stable. The one that won't have any effect on performance will be undervolting, where you supply less power to the CPU but it (hopefully) remains completely stable without any loss in performance. There are a few things you can do to lower your CPU's temperatures using XTU. If your CPU is thermal throttling then it would explain why you would see a drop in fps while playing games.
