    G750JZ - Thermal Throttling ocing gpu as well as power throttling on cpu.

    Hello ROG! Name's Sean McCargar,

    Was wondering if I could get your help with my G750JZ laptop thermal throttling and power throttling.

    When ever overclocking the GPU (880m 4gb) the laptop starts having really bad thermal throttling even tho the temps never go above 80c on the GPU. The CPU core clock drops quite a bit and constantly from the stock OC (3.4 Mhz) to 2.6 in some cases even tho the CPU is not overheating sitting around 65c.

    As well I was wondering if I could get some insight into power throttling. On stock OC for the CPU (3.4 Mhz) while
    stress testing power throttling will kick in to 100% and lower the core multiplier. I've tweaked my settings and found out that with a -60mv core voltage offset on the stock OC setting (3.4 Mhz) seems to fix this issue and no longer power throttles.

    Now the thermal throttling is the real issue here. It seems like its built into the bios to engage thermal throttling even tho the laptops not overheating. While OCing the CPU never goes over 65c and the GPU never over 80c. The GPU does not lower in performance but spikes downwards to 340Mhz in 1 second then right back up to my GPU OC.

    When monitoring the thermal throttling and the CPU, thermal is about 5% to 10% max and the CPU core is jumping all over the place, inherently causing the GPU to spike down to 340Mhz.

    Now for the G551JW a beta bios was created and released for more thermal headroom. About 5 degrees from what Ican see on the forum. Since there is no real way of me getting around it because I don't have the options in my bio
    to edit them, I was hoping for a beta bios for the G750JZ for upping the thermal limit.

    Once again the laptop is not overheating at all and runs perfect at stock settings (except for the CPU power throttling on max load, which needs to be discussed).

    If this is possible please get back to me or give me some insight into why the thermal throttling is kicking in before the 92c on the GPU and the 92c on the CPU.

    Thank you Republic of Gamers for your time!
