Does My Motherboard Help Twin GPU? How To Examine


Ever questioned, ‘Does my motherboard assist twin GPU’? If that’s the case, you’ve come to the correct article.

I’ll be educating you what you could find out about twin GPU know-how and detecting its presence in your motherboard right this moment, so let’s not waste any time diving proper in!

A Transient on Twin GPU Expertise

So, twin GPU know-how is generally precisely what it appears like. It’s extra like “Multi-GPU know-how”, because it isn’t restricted to simply two GPUs, however the assist for it will be dependent in your particular motherboard.

It doesn’t assist that the 2 largest GPU distributors (AMD and Nvidia) have totally different applied sciences for dealing with multi-GPU assist, which often aren’t supported on the identical motherboard directly.

Listed here are the multi-GPU applied sciences you’ll be searching for:

  • AMD CrossFire — AMD’s tech for supporting a number of GPUs in the identical PC, with or with out interconnected shows.
  • Nvidia SLI — Nvidia’s tech for supporting a number of GPUs directly, with or with out interconnected shows.
  • Nvidia NVLink — Nvidia’s up to date multi-GPU know-how, including a bodily NVLink bridge and a efficiency enchancment in comparison with customary SLI. Wants motherboard assist like the opposite two, although.

Supply: PC Information

After all, particular workloads, like rendering in most GPU render engines, don’t require you to attach two or extra GPUs bodily. Regardless that e.g. NVLINK permits for Reminiscence / VRAM sharing throughout GPUs, this isn’t strictly obligatory, particularly if you’re engaged on easier scenes that simply match into every GPU’s personal VRAM pool.

So, Twin-GPU can consult with each, linking two or extra GPUs bodily, however also can imply you simply need to use two GPUs inside one PC.

Let’s cowl each beneath:

Does My Motherboard Help Twin GPU (Two GPUs)? How To Examine

Confirm PCI Specific x16 Slots (full-length) On Your Motherboard

Motherboard form factors

Relying in your motherboard kind issue, you’ll have a unique variety of PCI Specific slots.

Some boards might use PCIe slots as a spot for M.2/NVMe drive mounts as an alternative, which can provide a multi-GPU setup extra room to breathe so long as your bridges (if required) account for the elevated distance between playing cards.

Mini ITX merely received’t assist multi-GPU in any respect, whereas Micro ATX turns into bodily able to supporting 2 GPUs, and ATX/onward can probably use 3.

Sadly, the existence of the PCIe x16 slots doesn’t assure the presence of the Lanes or the motherboard function required for multi-GPU assist: the subsequent step requires nearer inspection.

Confirm Motherboard Mannequin

Because it seems, multi-GPU assist is a motherboard-specific factor.

You’ll have to seek out your motherboard’s mannequin quantity and lookup its specs to find out what multi-GPU know-how, if any, it helps. This data may be accessible as a sticker on the field or bullet level on the unique product web page.

I’ve even seen “SLI Enabled” and “CrossFire Prepared” textual content in plain sight on some motherboards’ precise PCBs.

Examine PCI Specific Lanes Supported

Pro vs chipset allocated lanes

When you’ve confirmed whether or not your motherboard helps SLI/NVLink/CrossFire or not, you’ll nonetheless need to double-check its PCI Specific Lanes spec.

Your most supported PCIe lanes can even add a restrict to your efficiency with a number of GPUs or probably even a number of NVMe storage drives. Multi-GPU setups additional emphasize the significance of a high-end motherboard on account of calls for like this.


Right here’s tips on how to examine in case you can run twin GPU together with your motherboard:

  1. Examine the variety of PCIe x16 slots in your motherboard (both visually, from product pictures or from the handbook / specs web page)
  2. Examine your motherboard specs to see if it allocates enough PCIe-Lanes to every of these PCIe x16 slots or if, e.g., storage units, “steal” lanes from PCIe slots
  3. If you wish to use bodily GPU connections equivalent to NVLINK or SLI, your GPUs have to assist this, in addition to your workloads


Can Intel GPUs Be Run In Twin GPU?

Sure, though there are not any devoted applied sciences like SLI or CrossFire which can be going to make them cooperate.

You’ll solely have the ability to use a multi Intel GPU setup for distributed workloads like video rendering.

Gaming with each of your Intel GPUs directly isn’t at the moment doable.

Intel Deep Link

Picture Credit score: Intel Deep Hyperlink Graphic

There’s additionally Intel Deep Hyperlink, which includes an Intel iGPU on an Intel CPU being synchronized together with your discrete Intel GPU. It solely works in choose rendering and enhancing functions, nevertheless it can enhance efficiency whether it is supported.

How Many GPUs Can You Use With out Bottlenecking?

As we’ve established on this article, dual-GPU isn’t essentially the restrict so long as your motherboard helps multi-GPU know-how to start with.

Nevertheless, it’s essential to notice that multi-GPU isn’t significantly well-supported by most functions or video games. When it’s, you typically shouldn’t count on an growing 2x, 3x scale in efficiency together with your GPU rely, however just a few significantly well-optimized titles can come shut.

Reasons for Multi-GPU Bottleneck

Anyway, for duties that can make the most of multi-GPU, the reply is generally going to rely in your motherboard.

Can You Run GPUs From Completely different Manufacturers In The Similar PC?

Separate from motherboard assist, you truly can run an AMD and Nvidia GPU in the identical PC, although your makes use of for them will likely be much more restricted than a daily dual-GPU setup.

The playing cards received’t work collectively in what few video games assist multi-GPU, rendering engines received’t run

What Sort of GPUs Are Finest For A Twin GPU Setup?

Types of GPU Coolers

Everytime you’re doing a dual-GPU setup, you may very well be better-served by “blower-style” GPUs than “open-air” GPUs.

Blower-style GPUs consult with GPUs with a blower-style cooler that primarily exhausts air instantly outdoors of the case. Many of the card is totally lined by the cooler, and there’s often just one blower fan sucking air in.

Open-air GPUs are the extra customary form of GPU cooler. They work equally to CPU coolers since they use a mixture of heatsinks and a number of followers pulling air from the remainder of the case.

Extra warmth tends to flee from an open-air GPU into the remainder of the case than with a blower-style GPU.

Does NVLink Require an SLI Motherboard?

Sure. Whereas NVLink works utilizing bodily bridges, enabling it capabilities the identical in-software (Nvidia Management Panel) as enabling SLI.

It’s even known as SLI in driver software program, nonetheless!

Over to You

And that’s all, for now!

I hope this text helped make clear tips on how to decide twin GPU assist to your PC. I simply want there have been extra sweeping solutions to offer, like each AMD motherboard supporting CrossFire or one thing (not essentially the case!).

It’s all the time finest to choose your motherboard fastidiously earlier than doing a multi-GPU setup if doable, and to confirm your current board and GPU mixture for compatibility earlier than trying an improve to multi-GPU.
