2Q?s [x570 Taichi]: The 2ndary GPU Slot is Connected to CPU not Chipset, Right? --- Will 4-pin 12v EPS help w/OC Stability?

Hey there my OC brethren; my title pretty much says it - I've just got a couple quick questions that someone with more experience can probably answer:






1) My Chipset is getting really hot; moving my GPU down a slot will probably help a lot, but I don't want to do that if my GPU throughput is going to be unsurreptitiously murdered. I don't see why it WOULD be connected through the chipset, but can't find any definitive information about my specific board, or x570s in general regarding their respective PCI-E trace topologies.


Edit: Or maybe I should consider getting a gpu riser?







2) I'm rocking an OC pretty hard on my 3900x; 4.4Ghz All-Core OC; which is ALMOST totally stable. I'm wondering if buying and connecting the extra 4-pin 12V motherboard connector will help at all. Most of the common information I heard regarding the subject of the 4-pin says something like, "If you aren't extremely overclocking it, you can leave out the 4-pin." or "If you aren't LN2 you don't really need the 4-pin." I don't really want to waste buying and shipping a product if 4-pin OC results are questionable at best. So, if anyone has any relevant real-world knowledge on the subject, or can maybe point me to a youtube video or maybe a tech write-up source on the subject I would be very appreciative for some guidance.




Thanks guys; keep on foldin'

Yes, 1st and 2nd PCIe are connected directly to the CPU and usually run at x16/x8 with Zen2 - so yes, you could use Slot2 without any loss.

Well 1st of all I would look into increasing airflow – as this helps all components.
2nd look into repasting changing the thermal pad from the heatsink of your chipset.

Well, you could try.
My best guess would be looking into bullzoids channel.

But at a price point for $5-$10 for such a connector - I would just try it out...
