I think it wouldn't necessarily work with all CPUs which is why it only comes with 1 M.2 slot. I think LGA1700 only natively supports 2 PCI-e devices from the CPU. So x8 x8 or x8 x4... no x8 x4 x4. On AM5 it could work with 2 M.2 slots.
generally fan controllers don't have OCP. So overloading a fan header leads to physical damage.
Also on the topic of VRM quality. Sometimes the component manufacturer screws up. Sometimes the mothboard manufacturer implements the components wrong.
you don't need watercooling to shove 1.8V into B-die. Just put a fan on it. The bigger issue you'll run into is the fact that allowing the OS to access and entire B-die stick when over 1.8V causes instability. I have a few videos running B-die at 4000+ CL12 and you need to set windows to only...
Well this might be the correct crystal for the card: https://www.digikey.co.uk/en/products/detail/ecs-inc/ECS-270-18-23B-JTM-TR/9953225 but I'm not 100% sure since I don't have the original part number to try match the specs. The one I linked is the correct frequency and size but might not be...
your oscillator crystal is also missing. Honestly I'd think the card was being used as a donor card or someone already failed at fixing it.
EDIT: Have you checked any resistances on the card? It's possible the person who pulled parts of it came to the conclusion that the core is dead(low Vcore...
The Tachyon is a 10 layer(Gigabytes website has a mistake on it). The Unify-X is an 8 layer. The ASUS Apex is a 8 layer. The Z690 DARK is 12 layers. the Z690 Aqua OC is also 12 layers.
Right now the Apex Tachyon and Aqua OC dominate the competitive overclocking scene. A big part of that is...
Some strage cable choices on this one. Especially with how common 3x 8pin GPUs are these days. A 1000W PSU should have enough EPS cables for HEDT CPUs. Should've at least used 16AWG on the dual EPS.
