...my slightly different 970s are technically different right?
It's a known problem with some 970s, probably due to different memory vendors (or memory architectures) used over time.
I can use SLI now but the control panel still suggests using an SLI connector, is this normal? I've tried flipping mine around and switching between both ports multiple times to no avail. It's totally possible my bridge doesn't work but it was new and sealed while being such a simple piece it seems unlikely to be the point of failure. I haven't seen any noticeable performance change whether or not it's connected though
Probably due to the suspected difference in memory vendors / architecture used in those cards, the data exchange over the SLI-bridge fails, leading to this error message.
Which means the data gets exchanged over the PCIe bus, which is not optimal and can hinder performance in some cases.
I'm wondering if it's as easy as booting into test mode any time I want to use SLI or if it's not so simple to switch between.
Test mode is needed in order to load the patched driver. If you disable it, Windows fails to load the patched nVidia driver and falls back to a generic Windows driver.
So there's no easy way to switch back and forth between an unpatched and patched nVidia driver.

Which guide did you follow?

There's never been a patcher which works with that driver version.

Latest matching patcher and driver versions are 1.7.1 & 388.71.
Installation is outlined in this post (start reading below the video):

Newer driver versions have to patched manually, using the offsets published by volunteers in this forum.
Hi i have a answer i see you say the version of differentsli 1.7.1 i want to prove with 2 gtx 1050 same model and vram where i can find the link please and what driver i have to install i see driver in 411

YES! I very much agree with you, the bridge can really bring huge performance improvements, I hope everyone who sees should prepare a bridge, even if you don't need it!
the new patch work but with equal gpu i want to probe with 2 gtx 1050

Two identical GPUs is very likely to work.
Generally, I recommend using the following instructions:
To get patch offsets for newer drivers, backread this forum.

Can sli hack work on non sli supported cards? like nvs cards?
I want to make a fun projekt G98 GPU quad sli. I know it is a very low spec and even if it works it will be like a 5-10fps in games but i want to try it.
Two Quadro NVS 450 (dual gpu, same pcie bridge chip as the 7950GX2) all gpus have 256mb ram, cards are same vendor, same type... (was 6 usd each card, and it is works on windows 10!)

There's a small chance this might work, if the cards still run under driver 388.71 (for Win 10), which can be patched with DifferentSLIauto 1.7.1.
For 2xx drivers, there's no patch available.
