Considering supply problems and the fact that you only need one bridge per SLI'd computer. Shouldn't there be a limit of 1 per household on these things to help spread the love more? I might be over thinking this but I don't see why there would be a limit of 2 on such an item.

So I just noticed something, when looking at gpu-z it shows this:
Notice how it says high-bandwidth on the SLI section. I do not have a HB sli bridge. What I have is one of the older style EVGA Pro 2-way sli bridges (http://www.memoryexpress.com/Products/MX47593)
I also noticed that even in the control panel it doesn't mention that a higher performance sli bridge could improve my experience. Any one know why it says that it is high-bandwidth?
So anyone have any idea why it is acting like I have the HB bridge when I don't? Jacob? Anyone?
It's most likely because the bridge is running at the same speed as the hb bridge. Tom Petersen @ nvidia said the older LED sli bridges are capable of running at the same speeds of the new hb bridge.
Ahh, I did not hear about that. Well in that case no need for me to spend the extra to get the HB bridge. Thanks for the help.

No problem. Yep, no reason to get the new bridge unless you're doing 4k @ 120-144Hz, 4k surround or 5k.

there are 2 other reasons to get a HB bridge, the color LEDs and that they offer a 4-slot spacing. Granted, they aren't great reasons like improved performance, but I want my SLI bridge LED to match my GPU LEDs :) (not sure if the 4 slot really does anything of note as far as cooling goes over 2 slot spacing, but I got that one because my motherboard supports that spacing and it was in stock lol) Also, quick question, would 5120x2880 (5k) from using DSR take advantage of the HB bridge? I assume it's rendered resolution that counts as far as data that needs to be shared between GPUs, not output resolution, but I'm not 100% sure on that.

Good question. Someone needs to test this.

Its not clear to me that same speed = same thruput. I would like to know if that is so, for a) 2-way old style led bridge, and b) old style 3 or 4 way led bridges.

Led bridges only connect the one SLI fingern so they have half the throughout of HB bridges. However, that extra isn't really needed until the 5k and above mark. It's been said before that the frame times in SLI will improve. Whether you notice is YMMV.

precisely. so saying they are the same speed without adding that caveat is less than the full story.

While I agree that using only one finger should mean that it has less bandwidth, why does gpu-z see it as high-bandwidth?

Because the older led bridges are running at the same 650MHz speed as the hb bridge when used with pascal video cards.

gpu-z developers probably need to differentiate between the two types of bridges that run at 650mhz since the new hb bridges have twice the data rate.

This is what I'm hoping my hb bridge will do for me , which should be sitting on my door step when I get off work today , I'm currently running a single sli ribbon cable and I'm getting right at 60 fps on ultra in the The Division , and crazy fps in Bf4 totally maxed out 140+ fps 4k not sure if the pic uploaded but it shows 57 fps in the division 4k ultra setting with a single sli ribbon about the same with dual ribbons and big jump to 73.fps with the new Hb bridge that's a big difference and what I'm hoping to see

Okay I can now confirm that in the division I was getting avg 55-60 fps at ultra setting but now with my new Hb sli bridge I am now seeing 70-80 fps that is a huge increase and I'm so happy that I got that Hb bridge not only am I getting a 20 fps increase but it's running so much smoother it even looks better The colors are more vibrant and shaper ! I only had a single ribbon sli bridge to test I didn't have 2 , I'm gonna run some more benchmarks later tonight

For $40+shipping, the HB bridge is worth it. I see smoother and higher fps running 7680x1440 at 120Hz than a single flex bridge. I actually held on to Crysis 3(unopened) until I replaced my old 3930 w/ 680SLI. Using ULMB with an Eizo with 2 PG279Q on the sides. Granted, I had to turn down AA, but everything else is on ULTRA or highest setting and I get at least 55-60fps on the most detailed levels that would normally get 27-35 using max AA settings in Crysis 3 surround gaming. This is on my new 5960x setup at 4.7GHz. I didn't think a future capped Titan would be better than 1080 SLI.
Only minor issue is FTW SLI generates some heat(72*/65*) and I got 8 case fans and an EK 360 push/pull(6 more 120s) in a Corsair 900D. Fans on 100%(gaming mode) with room ambient at ~23*c. Total system power on my UPS peaks at 860 watts load. Never thought I'd reached my capacity from my 1500va UPS with only 1 pc on it. A good problem to have...

I have an open order with Amazon for an HB bridge since June 30 all the while saying it should ship by Aug 2nd, and now Amazon says it won't arrive until Sept 1 - Oct 13! Seriously? Why is manufacturing so slow for these?

I have two 980s but I am thinking of getting two 1080s in the future. Does this new bridge work for 980s? Also, I have the band type bridge now. What is the performance difference of that and this new bridge? Is it worth getting now for me?

So the 72 C is the top card and the 65 C is the bottom card I am assuming, is this a 1 or 2 slot space setup? I have a single 1080 FTW right now and with the fan at 80% playing Witcher 3, it tops out at 71C. I have a 750D Airflow edition with 2 front 140s and 1 140 at the back and a Corsair H110i v2. Seeing how people report between 10 and 20 C added temp to the top card, I am a bit worried.

Yes, top card... after I moved (3) DP monitors to bottom card and added squirrel cage fans blowing towards the cards in my 900D at +75 core/+500 mem stayed in the mid 60s during stress tests when all case fans at 100%. Dual ftw with monitors in top card when SLI first installed made top card run in the low-mid 80s. +50core/+470 mem. That's when I moved the monitors and added the blower fans that were directed to the 100mm GPU fans. Originally, I wasn't planning to SLI FTWs, but had an opportunity. The HB does make a noticeable difference between the standard flex bridge at 7680x1440p 120Hz.

Thanks. 1-slot. Sorry, these are very old from my fan parts bin. You can search Newark, Mouser, or Digikey for centrifugal blower style 12v. Can't remember, but these were <30dB and are quiet. Main purpose to to direct focused air since SLI will generate some heat. I bought the nice $40 lighted HB bridge and didn't want to butcher the look too much. I think MSI has an older style bridge w/ a bracket for a fan above their cards. I think this would work well with FE cards. May not work as well with ACX cooling or water and block the purty lighted logos. I would buy that over that over the "L" power adapter or both ;) EVGA, How about a HB bridge with an attachable fan with programmable LED so you can create messages or pictures? The ultimate HB bridge solution or case accessory.

Did the stars line up just right that you were able to get your hands on that 1 slot hb bridge? Did you get it directly from evga since Newegg and Amazon don't seem to stock the 1 slot versions. With my luck I will find a second 1080 and won't be able to use it because I don't have an Sli bridge.

Got lucky. Day I picked up my 2nd FTW, tweeted Jacob. Signed up for auto-notify and next day, had limited stock. Almost bought the nVidia HB, but luckily I waited for EVGA. Plus, nVidia wanted +$40 shipping so I said screw them. Abouit to sign up for 1070 step-up and shipping said $71 FedEx. My FTW from EVGA shipped at $34 2nd day. Step-up shipping for FE is screwed up. I just may try the step-up for a FE and check out the OC and temps. If decent, I may sell my FTWs and go with EVGA FEs. Stupid lights don't match and ACX in SLI puts out some heat in the case.

I just may try the step-up for a FE and check out the OC and temps. If decent, I may sell my FTWs and go with EVGA FEs. Stupid lights don't match and ACX in SLI puts out some heat in the case.
After you added to squirrel fans, what temps did you land up getting and what was your fan curve like when your top card landed up running in the mid 80s? Also, does moving the monitor cables to the bottom card reduce heat on the top card?

Did the stars line up just right that you were able to get your hands on that 1 slot hb bridge? Did you get it directly from evga since Newegg and Amazon don't seem to stock the 1 slot versions. With my luck I will find a second 1080 and won't be able to use it because I don't have an Sli bridge.

100% GPU fan during stress tests for both. I wanted to see temps with all fans(AIO/case/GPU) at 100%. 900D has high and low pressure areas so I brute forced it. Dump a lot of cool air in and direct it toward the GPUs fan supply. I feel the warm air from the rear fan and perforated holes on the back. It hit in the 80s with all 1440p monitors plugged into Slot 1 GPU1 with Max 3D and surround gaming at 7680x1440. I moved all the monitors to slot 3 GPU2 and added the blower fans together. FWIW, moving to 2nd card helps temps, but you lose BIOS access. I used my DVI on my primary mon and switch inputs during boot for BIOS access. I did things so quickly after I got the HB bridge that it was probably a combo of things that increased and decreased temps. Scientific methodology and baseline references went out the window when... holy $h!+, it's in stock and tracking the shipment to my house.

Anyone else here with an SLI HB Bridge confirm that you get very strange VRAM readings from Precision X OC 6.0.4? I didn't take a screenshot but while I was testing the system noticed the precision would read some 4+ million Mb of VRAM usage which is obviously a bug, didn't happen with my ribbon bridge though. The good news is though, coming from a single ribbon cable the increase in performance is noticeable with scaling increased significantly and frametimes much more consistent. This is at 4K60Hz.

I monitor my osd very closely and I haven't noticed any unusual reading such as yours , but I can also confirm a major improvement in framerates and performance overall with the Hb bridge
