Innocent White: KFA2/Galax GTX 1070 Ti Hall of Fame under review

What is white, slightly overweight and even really fast within the framework of their genes? No, we are not writing about a full Snow White on Speed, but the Galax GeForce GTX 1070 Ti Hall of Fame, which is held in Europe for trademark reasons. KFA2/Galax uses a modified GTX 1070 Hall of Fame board for the GTX 1070 Ti Hall of Fame, but with slightly improved assembly. This, in turn, is not a cost-down, but also takes into account objections from our previous reviews similar to... Important preliminary remark We had already mentioned it at the beginning that almost exclusively the resulting boost clock rates of each GTX 1070 Ti determine the final performance and thus the so-called GPU lottery and not the manufacturer and model.... Power consumption at different loads The power consumption in the Torture Loop is pretty much exactly on the point that Nvidia set as the Power Target with 180 watts. In the gaming loop, the power consumption of 174 watts is even below the... Overclocking The limits of this card are far higher than those of the competitors with similar Power Target, which is of course also due to the already mentioned good GPU quality. however, this alone is of little use if the tension is... Cooling system and backplate Of course, the generated waste heat is directly related to the recorded power, for which the cooling solution is responsible for optimum dissipation. This rather massive cooling relies on a large lamellar... Summary White card, white vest? Almost, because the manufacturer does not make any real mistakes except for the trimmed chip (for which he can't do anything). On the contrary, it is only by changing the voltage converters to eight ech...

KFA2/Galax uses a modified GTX 1070 Hall of Fame board for the GTX 1070 Ti Hall of Fame, but with slightly improved assembly. This, in turn, is not a cost-down, but also takes into account objections from our previous reviews of similar HoF cards. The most visible change concerns the coils used, where the manufacturer now relies on better, encapsulated ferrite core coils. This will be heard later, or in this case, it is not.

On the right side we also see the small DIP switch for BIOS switching. We couldn't find out why the part is so hidden. Galax said on request that it was for internal use and was not currently needed. We'd rather assume that we could have switched to a different BIOS here and that the planning for this was already done before Nvidia's tough restrictions.

The GPU power supply is a true 8+3 phase, but doubler has been intentionally dispensed with. To achieve this, as with the GTX 1080 Ti Hall of Fame, an IR 3595A from International Rectifier is used, which, according to the graphics card manufacturer, offers more adjustment and access options. However, OpenVReg 4+ is also on board with this chip.

Due to the now larger coils, one deliberately dispenses with the phase doublers and controls the eight PowIRStage chip IR3555 directly. These highly integrated chips contain the two MOSFETs for the high and low sides, as well as a Schottky diode and the gate drivers.

The power supply of the memory is released via an uP9509 from uPI Semiconductor, which can provide the total of three phases as a buck controller. The control is applied by one MDU1514 on the high side and one MDU1511 on the low-side, both from MagnaChip.

The back is, except for some voltage converter MOSFETs for the peripherals, largely free of larger active components. The voltage converter range seems very tidy and one could have taken the opportunity to actively integrate the backplate into the cooling by means of a thermal pad. But it is enough, as we shall see in a while.
