The master of the white PCB GPU has for a long time been KFA2 / Galax.

In my eyes historically this manufacturer in the HOF line of products not only have the best white PCB cards but also regularly the best GPU of any board partner period.

When I was asked to pull a card from our stock to review I jumped at the chance to see if there 1080 was a worthy addition to the HOF line. On unboxing the card it looks truly stunning. It has a very substantial 3 fan cooler which is 3 slot sized. This 1080 HOF can be used in a maximum of two way SLI configuration. The card comes with a full length back plate adding to the slick look of the product as well as ensuring no flexing of the PCB. This PCB is huge offering twice the Power phases to GPU than the standard 1080 Founders Edition in its 10+1 phase design.

Here are some pics of this gorgeous looking offering in my test rig.




We have established from the pics above this card looks great and the general feel of the product is quality. So lets see how it performs in my standard X99 review system.

Test System:
6950X 4.5
ASUS R5E10
16gb Team Xtreme mems 3200mhz
8Pack 2000w PSU

Stock Benchmarks









Thermals
Auto Fan

Turbo button pushed(100% fan)


Overclocked Performance.










Conclusions

Firstly looking at stock figures the HOF is producing some very impressive numbers in testing. The stock boost GPU clock is 2038mhz which is as high as I have seen of any Pascal GPU straight out of the box beating the previous best ASUS Strix OC by 13mhz. Needless to say at these clock speeds it also beat every card I tried before in pure out of the box performance across all the benchmarks. For those not wanting to OC this is the best card period.

Now lets check the performance of that huge cooler. To do this I ran Heaven at 4K res with all the details including tessellation maxed out for one hour and monitored the temps. With the fan profile at auto which was very quiet indeed and certainly inaudible over the AIO cooler fans on the CPU the peak temp of the GPU was 60C. At this temp the frequency of the GPU remained locked at its full boost speed of 2038mhz. A very impressive result. Even better thermal performance resulted in pressing the boost button on the IO. This is for benching only really as the fan noise is much greater but temps are now even more impressive. After my one hour heaven run they now peaked at a crazy low 47C which is in water cooling territory!!! In summary the cooler is looking great but cooling even better.

The 1080 HOF Overclocked to a very solid 2138mhz Core and 5580mhz mems. This produced a healthy gain in the bench marks. The HOF reached these numbers with no voltage tweaking, no power limit changes and no fan profile adjustments. What I found impressive was not only these great benching scores but the fact that the boost clock was completely stable so no power limit adjusting frequency during bench runs or games. With this performance was consistent without any kind of custom bios or tweaking. I also found that these clocks where 100% game stable when I tried several games over numerous sessions. So not just bench stable clocks but game stable too which you very rarely find on any GPU.

In short I would highly recommend the KFA2 / Galax 1080 HOF. It looks amazing, is built to the highest standard with solid PCB design and power delivery. The cooler is quiet and very effective. Finally and most importantly the performance out of the box was the best of any 1080 I have seen and the overclocked performance of a random sample also very good too with zero tweaking needed to ensure no power limiting or clock fluctuations under load. This adds extra performance to your games while not adding any noise. The HOF is a truly a class leading 1080.

Very impressive stock speeds and to maintain over 2.1GHz when overclocked with no voltage, power limit or custom fan profiles makes it even more impressive.

You should try to push 2.2+ with some tweaking and then get it under some LN2. ;)

2138mhz for £750, some of the FE cards and a lot of the random other cards have managed close or about that, what exactly are you paying for except the pimp factor?

Almost identical overclock to what I can get on my card in terms of Heaven performance but I have no doubt you'd get even more out of my card! My card was one of the much cheaper ones with a noisy cooler though. I'm not convinced with 1080 differentiation. If my own efforts can match the worlds best overclocker then somethings not quite right and that's not a slur on your skills as I'm damn sure I couldn't even come close to your CPU/other gpu oc's. it simply shows that 1080's are identical performacne wise.

To me there seems to be some sort of bios locked limit which is limiting all 1080's at present. It's not difficult to find that limit hence why some random unskilled guy can get an identical Performance from his own card.

I think we need to see more power through it to see what it can really do, like others have said its only achieving what founders cards can do, under water to keep the clock stable though of course.

beam-X. go and dodge traffic on the m1 pls.

8 pack - nice one for getting one onto the bench. not many people have posted results with this card. it's just a work of art.

any word that kfa will release a bios to allow going beyond 1.09v like Asus xoc bios ?

re: FE comments above. for air users I would still buy one of these over an FE, no contest. even at 700 sheets. serious water coolers are stuck with the Strx OC imho and you need to bribe gibbo to get one.

yes I would still buy one because it's a wonderous piece of engineering. I am going to put on the hat of shame.
