Just test with V4 xb2.1 : no BSOD or crash.

Hi So once it's connected it wont do watchdog error anymore? Thanks

Ho .... I cannot confirme this !!
But I think it can help.
But be carefull, check polarity before ! It's not a PCIe power cable for GPU !

Hi itou,

Thank you so much for posting the pic! Now I see, that connector is not being used on my rig!

I remember you mentioning to be careful with the polarity? I don't know what that means but it sounds like I would be a specific type of power cable that goes into my 1600w psu? Just don't use the gpu power cables?

As I can't find this type of power cable, I have done it with PCIe 6 pin - to 2 molex adapter by rewiring only 12V and GND on the right pin. Check the pinout in the motherboard manual.
here is an explannation for this type of power cable : https://www.lifewire.com/atx-6-pin-12v- ... ut-2624580

Many thanks! I'll post the results soon. *fingers crossed*

Almost after each rendering session my pc with ASUS ROG RAMPAGE VI EXTREME (it has 3 x 1080s and a netstor box with 4 x 1080s) freezes to where nothing moves or afterburner shows no GPUs and windows says nvidia failed to start. PC must be restarted after this. It seems that the problem is even worse when rendering Phoenix fluids. I tried all the drivers and have the latest BIOS. Not sure what else can be updated. All other PCs work fine. I guess shouldn't have bought asus board. Thanks

Same issues on the RedShift forums. I have confirmation that Nvidia is aware and actively working on the problem. The cause- specifically the PLX feature in Asus X99 motherboards. Anyone else who is having trouble should send a support ticket to Nvidia to speed things up and keep the pressure on them to get this resolved soon.

Does anyone have this motherboardASUS ROG RAMPAGE VI EXTREME?
PC would just freeze while rendreing every day. Please let me know if you have same board and problem.

Thanks

coilbook I am looking for a new mobo at the moment. So I read a lot of things. That board was under my radar also but then I found the VRM cooling seems like to be a bad design decision there (asus traded the cooling power of a finned VRM heatsink against a "better looking" kind of blocky heatsink).
have you watched the vrm temperatures while rendering?
There is a ongoing discussion about the bad vrm cooling of todays "mainstream" x299 board lineup (the vrm coolers on the workstation boards like the sage seem way better).
just google "x299 vrm desaster"

have you overclocked your cpu?

if your vrm is getting too hot installing a fan somewhere on top of it and blowing down could stabilize your system.

cheers

EDIT: I just reread your config and saw you are using a nestor box. I don't know much about them but I guess there must be PLX chips involved (on the nestor board)? It's connected via the 4th pci slot? So maybe you just got the same driver issue as the other users have with PLX chips on their motherboards. have you tried the solution that works for some of them?
