Find the BIOS update that enables undervolting for the Precision 7540?
I own a Dell Precision 7730 that seems to have a burnt-out VRM. It powers off before reaching the desktop screen, usually remains stable in BIOS. Sometimes it takes a long time to boot, but after entering my Windows password, it goes directly to the desktop and then shuts down without warning. This issue has persisted for two weeks following intense gaming sessions. Online sources mention this model is prone to this problem. I've replaced the CMOS battery and applied thermal grease to the CPU/GPU, yet I can't get it to load into Windows without disabling certain CPU features and overclocking settings.
In that situation, replacing the motherboard might be necessary. I noticed a 7730 motherboard is more affordable than a 7530 one. My GPU appears to be okay. I was thinking about getting a 7730 if my GPU would fit, given I still have the RAM. Google says the original 7730 came with a Quadro P3200, but it's not clear whether a 7530 motherboard would work with it. I might also need a new heatsink assembly. Thoughts?
Welcome to the forums, newcomer!
If you're swapping out the motherboard in a laptop, it's best to choose a board that matches closely. When comparing these two options:

Buy Dell Precision 7730 System Board with Motherboard V490F

The boards may share similar port locations, but the internal structures differ, so your cooling setup might also change. You could reach out to the seller and check the component and port positions against the 7730, though a clear confirmation isn't guaranteed since Dell often updates their motherboards within the same generation to avoid future compatibility issues.
Regarding your GPU inquiry:

Both spec sheets indicate they include the 6GB Quadro P3200.
Thank you for your message. I wasn't focusing on the 7730 motherboard specifically, but I was trying to determine a suitable place to relocate my graphics card to save costs. It seems it could be beneficial to either swap in under $100 for a replacement of the 7530 motherboard or purchase another 7530 or 7730 on eBay without additional OS or SSD, and simply move your SSD to them.
Additionally, it appears a 7540 will work with my Quadro P3200 GPU. Could you assist me in locating the appropriate heatsink for a Dell Precision 7540 equipped with an i9-9880H CPU when paired with the Quadro P3200?
It seems like the part number is: TW1KC
I heard the heatsinks/fans setup was special for that particular GPU/CPU pair. The one I considered had different components than the original, which is why I inquired about alternatives.
But in the end, I chose a 7740 with Xeon hex core. Now, thinking about my laptop, besides keeping the keyboard as a backup, I thought about adding some RAM inside. Perhaps I could sell the motherboard that includes the GPU.
This seems to be a backup now, unless I decide to sell it. I updated the title to match this situation.
I'm wondering about the best BIOS version for the 7540 to enable undervolting. My 7530 still has Intel XTU and most features are grayed out, which might be similar for this new model when it comes. I think I might consider slightly lowering the CPU voltage and further reducing GPU voltage since it uses more than double the power of my current card.
According to my understanding, these controls won't be unlocked through any BIOS settings.
