We could certainly do more tuning, but that was sufficient to keep temperatures in check and still wasn't overly loud. Basically, we set the fan to a 50 percent minimum and gave it a steady ramp from 50 percent at 40C up to 100 percent at 80C. That last one is critical for maintaining a stable overclock, as sticking with a default fan curve tends to lead to periodic crashes. For the GPU, 150 MHz was nearly stable but crashed in two tests, so we dropped down to a 140 MHz overclock that completed the full test suite.īesides changing the memory and GPU clocks, we also increased the power limit to the maximum 110 percent and adjusted the fan curve. Eventually, we stuck with a 1000 MHz overclock on the RAM (the best-case maximum would be in the 1000-1250 MHz range, based on our testing), giving an effective data rate of 16Gbps. Test it out for stability and if it remains stable then the temps under load should be lower than stock without sacrificing performance.We were nearly able to max out the GDDR6 overclock at 16.5-17Gbps, but the EDR feature (Error Detection and Retry) meant performance was actually slower than a lesser RAM OC.
Then pull every point on the curve to the right back down to create a flat line at 1700mhz. 0.8v, is that is representing the voltage target hits the frequency target for say 1700mhz. Hold the shift key and drag the curve up so that the point, say. To undervolt use afterburner open the performance curve. Undervolting is a form of overclocking making the gpu run at frequencies higher than stock for a given voltage level that is lower than stock. Swapping bios to make the gpu pull higher wattage can get better scores for short workloads but more watts = higher temps and higher power draw that may exceed the vrm capacity that msi implemented for the unit so swapping bios in your machine could end up bricking the laptop. If you you are now working within a strict envelope of performance due to the size of the cooler that fits in the chassis. Laptops have cooling limitations compared to a desktop that can potentially have unlimited cooling. I with a 150 boost over lock I see 2100mhz regularly I have a 130w 3060 in my Lenovo Legion 5 pro. As temps increase the frequency will start dropping back along the curves until temps flatten out in line with your cooling capacity. Lġ700 or 1800mhz sounds about right for a 75w gpu.
It is it automatically overclocks your gpu up to temp, and power limits that are defined by performance curves built into the bios. Nvidia gpus have a feature called gpu boost.
