NVIDIA is working on a fix to allow the HTC Vive to be connected to the GeForce GTX 1070 and GTX 1080 over DisplayPort. The HTC Vive apparently has the choice between HDMI and Mini DisplayPort, but the headset will not be identified when connected over that connection. Currently, the two workarounds are to connect the HTC Vive over HDMI, or use a DisplayPort to HDMI adapter if your card's HDMI output is already occupied.

It has apparently been an open issue for over a month now. That said, NVIDIA's Manuel Guzman has acknowledged the issue. Other threads claim that there are other displays that have a similar issue, and, within the last 24 hours, some users have experienced luck with modifying their motherboard's settings. I'd expect that it's something the can fix in an upcoming driver, though. For now, I guess plan your monitor outputs accordingly if you were planning on getting the HTC Vive.

Getting a custom-cooled GTX 1080 (for around its MSRP) basically involves monitoring Newegg for a good business week or two, several times per day, pouncing on whatever isn't marked-up. Whether it's low supply or high demand, add-in board vendors haven't stopped announcing new models.

The MSI GTX 1080 8G DUKE is a three-fan (“TriFrozr”) design with an 8-pin and a 6-pin PCIe power connector, which provides 75W more headroom than the Founders Edition. EXPReview claims that it slides between the AERO and the GAMING lines. Although they don't claim how it matches up to ARMOR, which is also between AERO and GAMING, it looks like it's slightly above it, with its RGB LEDs. The GTX 1080 GPU is factory overclocked to 1708 MHz and boosts to 1847 MHz, and the GTX 1070 is overclocked to 1607 MHz with a 1797 MHz boost.

Launch regions are not listed for the cards, but the launch price is supposedly 5399 Chinese Yuan (which converts to $810 USD) and 3499 Chinese Yuan ($524.70 USD) for the GTX 1070. This is quite a bit higher than we would expect, but I'm not sure how regional pricing on electronics works between the USA and China.

It is rather difficult to rate the cost to performance ratio of GTX 1080's as the prices and availability are in a constant state of flux but we can certainly peg the overall performance of the cards.  [H]ard|OCP recently strapped the new ASUS ROG GTX 1080 STRIX GAMING GPU to their testbed to see how it performs.  Right out of the box the cards base clock is 1759MHz with a boost clock of 1898MHz and 10GHz GDDR5X, which [H] successfully raised to 1836MHz base, 1973MHz boost with in game frequencies reaching 2139 MHz and the GDDR5 running at 11.3GHz.  This had an effect on performance.

ASUS Responds to GTX 1080 "Reviewer VBIOS" Concerns

Subject: Cases and Cooling | June 17, 2016 - 12:52 PM |
Tagged: asus, GTX 1080, strix, vbios

Yesterday, there were several news stories posted on TechpowerUp and others claiming that ASUS and MSI were sending out review samples of GTX 1080 and GTX 1070 graphics cards with higher clock speeds than retail parts. The insinuation of course is that ASUS was cheating, overclocking the cards going to media for reviews in order to artificially represent performance.

MSI and ASUS have been sending us review samples for their graphics cards with higher clock speeds out of the box, than what consumers get out of the box. The cards TechPowerUp has been receiving run at a higher software-defined clock speed profile than what consumers get out of the box. Consumers have access to the higher clock speed profile, too, but only if they install a custom app by the companies, and enable that profile. This, we feel, is not 100% representative of retail cards, and is questionable tactics by the two companies. This BIOS tweaking could also open the door to more elaborate changes like a quieter fan profile or different power management.

There was, and should be, a legitimate concern about these types of moves. Vendor one-up-manship could lead to an arms race of stupidity, similar to what we saw on motherboards and base frequencies years ago, where CPUs would run at 101.5 MHz base clock rather than 100 MHz (resulting in a 40-50 MHz total clock speed change) giving that board a slight performance advantage. However, the differences we are talking about with the GTX 1080 scandal are very small.

  • Retail VBIOS base clock: 1683 MHz
  • Media VBIOS base clock: 1709 MHz
  • Delta: 1.5%

And in reality, that 1.5% clock speed difference (along with the 1% memory clock rate difference) MIGHT result in ~1% of real-world performance changes. Those higher clock speeds are easily accessible to consumers by enabling the "OC Mode" in the ASUS GPU Tweak II software shipped with the graphics card. And the review sample cards can also be adjusted down to the shipping clock speeds through the same channel.

strix-1080-box.jpg

ASUS sent along its official statement on the issue.

ASUS ROG Strix GeForce GTX 1080 and GTX 1070 graphics cards come with exclusive GPU Tweak II software, which provides silent, gaming, and OC modes allowing users to select a performance profile that suits their requirements. Users can apply these modes easily from within GPU Tweak II.
 
The press samples for the ASUS ROG Strix GeForce GTX 1080 OC and ASUS ROG Strix GeForce GTX 1070 OC cards are set to “OC Mode” by default. To save media time and effort, OC mode is enabled by default as we are well aware our graphics cards will be reviewed primarily on maximum performance. And when in OC mode, we can showcase both the maximum performance and the effectiveness of our cooling solution.
 
Retail products are in “Gaming Mode” by default, which allows gamers to experience the optimal balance between performance and silent operation. We encourage end-users to try GPU Tweak II and adjust between the available modes, to find the best mode according to personal needs or preferences.
 
For both the press samples and retail cards, all these modes can be selected through the GPU Tweak II software. There are no differences between the samples we sent out to media and the retail channels in terms of hardware and performance.
 
Sincerely,
ASUSTeK COMPUTER INC.

While I don't believe that ASUS' intentions were entirely to save me time in my review, and I think that the majority of gamers paying $600+ for a graphics card would be willing to enable the OC mode through software, it's clearly a bad move on ASUS' part to have done this. Having a process in place at all to create a deviation from retail cards on press hardware is questionable, other than checking for functionality to avoid shipping DOA hardware to someone on a deadline. 

As of today I have been sent updated VBIOS for the GTX 1080 and GTX 1070 that put them into exact same mode as the retail cards consumers can purchase. 

We are still waiting for a direct response from MSI on the issue as well.

Hopefully this debacle will keep other vendors from attempting to do anything like this in the future. We don't need any kind of "quake/quack" in our lives today.

GeForce GTX 1080 and 1070 3-Way and 4-Way SLI will not be enabled for games

Subject: Graphics Cards | June 8, 2016 - 08:44 PM |
Tagged: sli, pascal, nvidia, GTX 1080, GP104, geforce, 4-way sli, 3-way sli

IMPORTANT UPDATE: After writing this story, but before publication, we went to NVIDIA for comment. As we were getting ready to publish, the company updated me with a shift in its stance on multi-GPU configurations. NVIDIA will no longer require an "enthusiast key" to enable SLI on more than two GPUs. However, NVIDIA will also only be enabling 3-Way and 4-Way SLI for a select few applications. More details are at the bottom of the story!

You'll likely recall that during our initial review of the GeForce GTX 1080 Founders Edition graphics card, we mentioned that NVIDIA was going to be moving people towards the idea that "only 2-Way SLI will be supported" and promoted. There would still be a path for users that wanted 3 and 4 GPU configurations anyway, and it would be called the Enthusiast Key.

As it turns out, after returning from an AMD event focused on its upcoming Polaris GPUs, I happen to have amassed a total of four GeForce GTX 1080 cards.

01.jpg

Courtesy of some friends at EVGA and two readers that were awesome enough to let me open up their brand new hardware for a day or so, I was able to go through the 3-Way and 4-Way SLI configuration process. Once all four were installed, and I must point out how great it is that each card only required a single 8-pin power connector, I installed the latest NVIDIA driver I had on hand, 368.19.

driver2.jpg

Knowing about the need for the Enthusiast Key, and also knowing that I did not yet have one and that the website that was supposed to be live to enable me to get one is still not live, I thought I might have stumbled upon some magic. The driver appeared to let me enable SLI anyway. 

driver1.jpg

Enthusiasts will note however that the green marker under the four GPUs with the "SLI" text is clearly only pointing at two of the GTX 1080s, leaving the remaining two...unused. Crap.

At this point, if you have purchased more than two GeForce GTX 1080 cards are simply out of luck and are waiting on NVIDIA to make good on it's promise to allow for 3-Way and 4-Way configurations via the Enthusiast Key. Or some other way. It's way too late now to simply say "we aren't supporting it at all." 

03.jpg

While I wait...what is there for a gamer with four GeForce GTX 1080 cards to do? Well, you could run Ashes of the Singularity. It's multi-GPU mode uses MDA mode, which means the game engine itself accesses each GPU on its own, without the need for the driver to handle anything regarding GPU load balancing. Unfortunately, Ashes only supports two GPUs today.

Well...you could run an OpenCL based benchmark like LuxMark that access all the GPUs independently as well.

lux2.jpg

I did so, and the result is an impressive score of 17,127!!

lux.jpg

How does that compare to some other products?

luxmarkgraph.jpg

The four GTX 1080 cards produce a score that is 2.57x the result provided by the AMD Radeon Pro Duo and 2.29x the score of SLI GeForce GTX 980 Ti cards. Nice!

02.jpg

So there you go! We are just as eager to get our hands on the ability to test 3-Way and 4-Way SLI with new Pascal GPUs as some of the most extreme and dedicated enthusiasts out there are. With any luck, NVIDIA will finally figure out a way to allow it - no matter how it finally takes place.

IMPORTANT UPDATE: Before going to press with this story I asked NVIDIA for comment directly: when was the community finally going to get the Enthusiast Key website to unlock 3-Way and 4-Way SLI for those people crazy enough to have purchased that many GTX 1080s? The answer was quite surprising: NVIDIA is backing away from the idea of an "Enthusiast Key" and will no longer require it for enabling 3-Way and 4-Way SLI. 

Here is the official NVIDIA statement given to PC Perspective on the subject:

With the GeForce 10-series we’re investing heavily in 2-way SLI with our new High Bandwidth bridge (which doubles the SLI bandwidth for faster, smoother gaming at ultra-high resolutions and refresh rates) and NVIDIA Game Ready Driver SLI profiles.  To ensure the best possible gaming experience on our GeForce 10-series GPUs, we’re focusing our efforts on 2-way SLI only and will continue to include 2-way SLI profiles in our Game Ready Drivers.
 
DX12 and NVIDIA VR Works SLI technology also allows developers to directly implement and control multi-GPU support within their games.  If a developer chooses to use these technologies then their game will not need SLI profiles.  Some developers may also decide to support more than 2 GPUs in their games. We continue to work with all developers creating games and VR applications that take advantage of 2 or more GPUs to make sure they’ll work great on GeForce 10-series GPUs.
 
For our overclocking community, our Game Ready Drivers will also include SLI profiles for 3- and 4-way configurations for specific OC applications only, including Fire Strike, Unigine and Catzilla.

NVIDIA clearly wants to reiterate that only 2-Way SLI will get the attention that we have come to expect from the GeForce driver dev team. As DX12 and Vulkan next-generation APIs become more prolific, the game developers will still have the ability to directly access more than two GeForce GTX 10-series GPUs, though I expect that be a very narrow window of games simply due to development costs and time.

NVIDIA will enable support for three and four card configurations in future drivers (without a key) for specific overclocking/benchmarking tools only, as a way to make sure the GeForce brand doesn't fall off the 3DMark charts. Only those specific applications will be able operate in the 3-Way and 4-Way SLI configurations that you have come to know. There are no profiles to change manually and even the rare games that might have "just worked" with three or four GPUs will not take advantage of more than two GTX 10-series cards. It's fair to say at this point that except for the benchmarking crowd, NVIDIA 3-Way and 4-Way SLI is over.

We expect the "benchmark only" mode of 3-Way and 4-Way SLI to be ready for consumers with the next "Game Ready" driver release. If you happened to get your hands on more than two GTX 1080s but aren't into benchmarking, then find those receipts and send a couple back.

So there you have it. Honestly, this is what I was expecting from NVIDIA with the initial launch of Pascal and the GeForce GTX 1080/1070 and I was surprised when I first heard about the idea of the "enthusiast key." It took a bit longer than expected, and NVIDIA will get more flak for the iterated dismissal of this very niche, but still pretty cool, technology. In the end, this won't have much impact on the company's bottom line as the quantity of users that were buying 3+ GTX GPUs for a single system was understandably small.

GeForce GTX 1080s Are Available at Newegg Canada

Tagged: zotac, pascal, nvidia, GTX 1080, GP104, asus

Update @ 10:30pm, June 7th: Annnnnnnnd it's gone.

Update @ 9:45pm, June 7th: ASUS is now out-of-stock, so I crossed out the relevant links. ZOTAC is still around for now.

Update @ 8:45pm, June 7th: Turns out that it's also available on Newegg US. In fact, it's possible that both sites share from the same stock pool, at least for the US ASUS and US ZOTAC cards, given that Newegg Canada says it ships them from the US.

A couple of GeForce GTX 1080s are available at Newegg Canada at the moment. Both models, one from ASUS and one from ZOTAC, are listed at $909. This seems high, but it's actually the current US-to-Canada exchange rate from the $699 MSRP. If you were interested in the Founders Edition cards, then you have a brief moment to pick one up.

nvidia-2016-dreamhack-1080-stockphoto.png

That said, it's looking like the custom-cooled versions might be a better bet. The EVGA dual-fan GAMING SC ACX 3.0 version is listed at $824.99 CDN (~$635 USD) and, from what we've seen so far, seems to be quite a bit cooler than the Founders Edition (albeit we haven't tested sound levels yet). Those should be coming out fairly soon, and will apparently lean on the cheaper side of the Founders Edition fence.

But, if you don't care, go go go go go.
