What is the Blackwell lock voltage?
Hey there,
I’m trying to figure out a solution for this issue. I have an ASUS Prime RTX 5080 and after overclocking, the core voltage maxes out at 1.045V, which is really low for stable overclocking. I’ve tried different BIOS settings like Zotac, PNY, and ASTRAL, but nothing changed. Everything still ends up the same. I’m using MSI Afterburner and locking the curve settings, yet the limit voltage stays the same. I’m a bit confused—am I missing something or is this a locked setting?
Update your post with complete hardware details and operating system information. Provide the power supply specifications, including voltage, amperage, and age, along with its condition (original, build, refurbished, or used). List the disk drive specifications such as brand, model, and capacity, noting how full they are. Include a full list of all connected peripherals.
Nvidia has restricted the voltages since the 10 series if I recall right. They transferred all BIOS functionalities to an online service, giving them control over any OEM attempting to surpass their specifications. This prompted dedicated overclockers to redirect modifications to boost power directly or take over the VRMs, adjusting voltages through I2C or SPI (though I’m unsure which protocol they use). Enhanced cooling typically improves boost performance. For those not interested in physical modifications, investing in better cooling solutions with a water block and necessary accessories is the best approach.
My setup includes:
CPU: AMD Ryezn 9 9950X3D
MB: ASUS B650E-F Gaming
CPU Cooler: Arctic liquid freezer 360
GPU: ASUS Prime RTX 5080
PSU: Corsair RM1000x
SSD: Samsung 990 Pro NVMe 4TB
RAM: 2x 48GB 6000MHz
The only new parts are the RAM and SSD.
I plan to improve cooling with conductonaut, but I risk losing warranty since removal may void it. This is my last resort. I’ll experiment with software tweaks before considering better cooling solutions.
