Adding a second GPU to rig kills video output

Go to solution Solved by PhilsSoX,

SOLVED

 

I was making changes in the bios and still nothing was working until i realised non of my settings were saving. Because the Rig was a prebuilt it had some shitty custom Bios. Flashed it with the latest version and changed CSM settings to UEFI only. And it works. 

 

Thanks for all the help guys (Even if i'm £200 in the hole after the RM1000x purchase 🤣

Anyone got any idea why I get no video output at all when plugging in a second GPU to a rig?
 
I have two cards in one rig working fine. 2080super and 3060 . I have a prebuilt with a 3070 in and that works fine until I plug in my new 3060ti, then i get no video output. If I only run the 3060ti instead of the 3070 I get no issues, so the new card isn't to blame. Is it a bad PCI Slot on my mobo or something? Any help would be greatly appreciated.

it might be that those are two different cards

nvidia is very strict with sli with differnt cards

You can't sli or nvlink any of these. I think this is a multi gpu setup for different reasons.

Corsair CV550 which I realise is weak for the two cards, but I get the same result when running the cards on separate PSU's (one 750w)

Not got them in SLI, just trying to mine from the both. As I say I have one rig that's already running a 2080super and a 3060

Dual psu is always kinda hit or miss. A cv550 is not even enough to safely run a 3070 or 2080 super.

 

Best advise I can give is to start with a proper single GOOD QUALITY high power psu.

 

Pick at least a b tier unit from the psu tier list of 1000w or more.

tried one card in any slot?

My PCs: Desky | Beddie | Miney | Benchie

Things I need help with: (nothing at the moment)

Spoiler

none atm

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

Spoiler

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

Yeah one card and everything works tickateeboo. Although I haven't tried 1 card in the second PCI slot on its own yet

you can try doing that

For sure not hence why they are trying a dual psu thing but that is always a big hit or miss.

Awesome, you guys have been a big help. I'll get a beefy psu in the post and see how we go. I've just tried and 2nd slot works fine so it's 100% power delivery. Thanks again folks.

It's going to be close in being able to handle it. It is a VERY good psu but there isn't much headroom. The 3070 + 3060 config probably won't work because of the 3000 series power spiking but the 2080 + 3060 setup might work. Still I'd aim for the 1000w version.

Both cards are underclocked when mining though so power draw should be less than if i was trying to game on them? Alright I'll look at a 1000w, looks like im spending today 😅

So I bought an RM1000x and it has not solved the issue. Same behaviour. Both cards work fine individually and on either pci slot, but with both I get no video output. I hear the bios beep but it isn't getting to windows because I can't remotely connect to it. Really struggling for ideas now.

Can you connect it to a screen? Not just remote but actually connect it to a screen to see if it works?

Not sure what CPU or motherboard you are using, but have you tried turning PCIE mode to 3.0 in BIOS if you're 4.0 compatible?

I'm not actually trying to be as grumpy as it seems.
