I have two slots in my PC and the first slot is running a 5700XT, I want to put a 5600XT into the second but it is a 16x slot in 4x mode.  Has anyone put a 5600XT in a PCIE 16x slot that is running in 4x mode?  Will this work  for mining ETH or will it reduce hashrate?
A regular raiser works in PCIE  1X mode.
This is enough for mining.
If a coin has a dag file equal to 6GB, then you will need the same solution as was done for 4GB cards for mining Ethereum with a Dag file of more than 4GB.
This is a tuned miner and maerit board with PCIE 16x slot.
Are there motherboards that have several x16 slots on them? I belief more than one x16 slot will result in x8 mode? Correct me if I'm wrong here, I'm just trying to find a solution for zombie mode with 4gb rx570s
To answer your question, you need to study the characteristics of the motherboard.
As a rule, a regular motherboard for $ 100 has 1 GPU - x16 mode, 2 GPUs - x8 mode + x8 mode.
You need to look for a motherboard like this
ASUS X99-Deluxe
(x8 x8 x8 x8 x8)
Why do you need a zombie mode? It is no longer relevant for 4 GB of video cards for Ethereum mining, the hashrate is minimal.

There are many... for Threadripper, Epyc and Xeon processors, where proc+motherboard cost more than high end GPU

However, with $20k motherboard+proc, you can do CPU mining too

I think you're mixing 2 issues.

PCIe x1 is enough for mining, except for Nvidia LHR GPUs that include a lane test as one of their LHR triggers.

Zombie mode is a workaround for GPUs with only 4 GB of VRAM. It's a clever workaround, but only a workaround,
and it only allows mining at a significantly reduced hash rate. The solution is a GPU with more VRAM.

However, there is a connection between them. Zombie mode increases data exchange between the CPU and GPU
and requires more PCIe bandwidth. At some point it might bottleneck at x1 and reduce performance and may
work a little better at x2.

Yes 4x mode works for mining and this shouldn't bother you at all, you will still get the highest hashrate using 4x pcie slots it doesn't matter, I have 5x 5500XT in 6x pcie mobo and they work perfectly, all slots are 4x mode

Thank you
