this video is brought to you by the Corsair Vengeance k70 and k95 these

fully mechanical keyboards are designed for performance gaming visit Corsair.com

3
00:00:08,320 --> 00:00:16,880
vengance gaming to learn more welcome to what amounts to basically an unboxing

4
00:00:13,400 --> 00:00:19,439
and second look at the GeForce gtx770

5
00:00:16,880 --> 00:00:25,320
direct to you to from ASUS now I call it a second look because I've already had

6
00:00:21,880 --> 00:00:27,359
this card out of the box and I have

7
00:00:25,320 --> 00:00:32,960
actually already had a chance to Benchmark it so okay I'm going to spoil

8
00:00:31,039 --> 00:00:39,680
the surprise a little bit it's a GeForce GTX 770 which means it's based on the

9
00:00:35,239 --> 00:00:44,160
same GK 104 core as the gtx680 a fully

10
00:00:39,680 --> 00:00:47,360
enabled core to be more clear so okay so

11
00:00:44,160 --> 00:00:49,480
it's a GTX 680 no because it's clocked

12
00:00:47,360 --> 00:00:57,359
higher this one in particularly because it's an OC level card and it also has 7

13
00:00:53,399 --> 00:00:59,680
GHz gddr5 memory as opposed to the 6 GHz

14
00:00:57,359 --> 00:01:05,439
gddr5 memory that we found on the original GTX 680 now the first things we

15
00:01:02,480 --> 00:01:10,880
find inside are a nice black ASUS box with some gold printing on it as well as

16
00:01:08,479 --> 00:01:14,200
a bunch of accessories that we didn't get with our reference card that came

17
00:01:12,560 --> 00:01:19,159
direct from NVIDIA so it's interesting to see what ASUS includes so they've got

18
00:01:16,600 --> 00:01:23,560
a quick start guide as well as some drivers and GPU tweak software that

19
00:01:21,360 --> 00:01:30,200
you'd do well to download directly from the ASUS website and finally last but

20
00:01:26,520 --> 00:01:34,439
not least a dual six pin to single eight

21
00:01:30,200 --> 00:01:37,320
pin PCI Express power adapter next up is

22
00:01:34,439 --> 00:01:42,360
the card itself now the first thing you're going to notice about it in all

23
00:01:39,079 --> 00:01:44,799
likelihood is going to be the cooler the

24
00:01:42,360 --> 00:01:49,560
direct CU 2's cooler gets its name from The Copper heat pipes as well as the

25
00:01:47,759 --> 00:01:54,880
direct contact that they make with the GPU itself this improves thermal

26
00:01:52,040 --> 00:01:58,880
efficiency as well as improving overall performance of the card especially in an

27
00:01:56,840 --> 00:02:03,439
overclocked environment there are two fans on it Each of which is sealed

28
00:02:01,200 --> 00:02:09,280
against dust making it dust proof and adding to the longevity of the card and

29
00:02:06,280 --> 00:02:11,879
allowing them to cover a wider area of

30
00:02:09,280 --> 00:02:16,640
the card itself providing more air flow not only to cool the GPU itself because

31
00:02:14,519 --> 00:02:21,400
it's connected with these nice fat heat pipes to all of these fins but also the

32
00:02:19,239 --> 00:02:28,319
other components under the heat sink fins all over the entire PCB of the

33
00:02:25,400 --> 00:02:34,239
graphics card on the back of it we find not a whole lot that you can see except

34
00:02:31,640 --> 00:02:38,720
for a back plate this contributes to the rigidity of the card which is especially

35
00:02:36,160 --> 00:02:42,480
important when cards are get longer and heavier and they're installed in chassis

36
00:02:40,599 --> 00:02:46,920
that only really fasten them at the screws at the top here as well as the

37
00:02:44,400 --> 00:02:52,640
PCI Express slot and the last thing that we see are a couple of diagnostic LEDs

38
00:02:50,120 --> 00:02:56,400
right under the six pin and 8 Pin PCI Express connectors that tell us if

39
00:02:54,440 --> 00:03:01,480
there's any kind of a power problem causing the card to be nonfunctional

40
00:02:58,720 --> 00:03:06,200
direct cu2 cooler are also well regarded for their quiet operation and we did

41
00:03:04,319 --> 00:03:10,879
indeed have the same experience with this card so I can happily say that it

42
00:03:08,480 --> 00:03:15,280
sits proudly with the other direct cu2 cards that we've had the opportunity to

43
00:03:12,760 --> 00:03:19,599
play with here's a cool feature for liquid coolers and Tweakers and just

44
00:03:17,280 --> 00:03:24,200
generally guys who are willing to push the limits of their Hardware sort of no

45
00:03:22,159 --> 00:03:30,000
matter what the uh no matter what the risk by simply removing four screws on

46
00:03:27,480 --> 00:03:35,280
the back of the card you can remove the entire direct cu2 cooler this allows it

47
00:03:32,840 --> 00:03:40,720
to be cleaned or just completely removed and replaced with something else should

48
00:03:37,360 --> 00:03:42,239
you see fit although most people

49
00:03:40,720 --> 00:03:48,040
probably aren't going to bother with that you will have to break a seal in

50
00:03:44,360 --> 00:03:51,280
order to get the cooler off

51
00:03:48,040 --> 00:03:53,439
however that risk is entirely up to each

52
00:03:51,280 --> 00:03:59,159
individual user and check that out it comes apart just like that to reveal the

53
00:03:56,519 --> 00:04:05,120
way that the card is cooled so we get thermal go on the GPU itself no thermal

54
00:04:02,879 --> 00:04:09,720
pads present on the memory because of what I mentioned before the way that the

55
00:04:07,280 --> 00:04:13,480
direct2 cooler provides so much air flow to the rest of the card you don't really

56
00:04:11,480 --> 00:04:18,120
have to worry too much about that we can see the entire 8 plus 2phase power

57
00:04:16,000 --> 00:04:23,520
design this is compared to okay so 8 plus 2phase digital power design

58
00:04:20,759 --> 00:04:27,680
compared to the 5+ one phase analog power design that you're going to find

59
00:04:24,759 --> 00:04:31,720
on a reference card and a dedicated heat sink for the mosfets themselves that

60
00:04:29,919 --> 00:04:36,039
allows that that's the hottest part of the power delivery that allows them to

61
00:04:33,880 --> 00:04:40,680
stay cool now there's more to a custom PCB design than just designing the PCB

62
00:04:38,759 --> 00:04:44,360
you also have to use higher quality components if you're going to get any

63
00:04:42,000 --> 00:04:50,160
benefit out of it whatsoever so that's where isus is sap or super alloy power

64
00:04:47,000 --> 00:04:53,039
components come in most of the power

65
00:04:50,160 --> 00:04:58,400
delivery circuitry actually is comprised of these specially designed components

66
00:04:55,919 --> 00:05:03,720
that ASUS has engineered in order to deliver better over clocking better

67
00:05:00,880 --> 00:05:09,400
efficiency cooler operation longer Lifetime and this is sort of this hits

68
00:05:06,880 --> 00:05:13,960
pretty close to home for me less coil wine because coil wine is just annoying

69
00:05:12,199 --> 00:05:18,759
and then mind you so are dead cards and cards that consume more power for no

70
00:05:15,440 --> 00:05:20,479
reason but that was the rationale behind

71
00:05:18,759 --> 00:05:25,600
redesigning it in order to use their own components it was to achieve all of

72
00:05:22,840 --> 00:05:30,639
those things but how did it all work out in the end my final word on this card is

73
00:05:28,639 --> 00:05:34,800
going to be about GPU tweak and the actual results that we were able to

74
00:05:32,400 --> 00:05:40,360
achieve because all of this is fine in theory but what does it yield in the

75
00:05:37,360 --> 00:05:42,280
real world our direct cu2 card

76
00:05:40,360 --> 00:05:47,160
overclocked higher than our reference card take that for what it is this is a

77
00:05:44,639 --> 00:05:53,000
very small sampling but in our experience we did manage to get a

78
00:05:49,880 --> 00:05:56,360
slightly higher sustainable boost clock

79
00:05:53,000 --> 00:05:58,720
okay so it was only 35 or so some odd

80
00:05:56,360 --> 00:06:04,000
megahertz higher than this particular card but there you go higher is higher

81
00:06:02,039 --> 00:06:09,960
and we did get better performance out of a direct cu2 card than we did out of a

82
00:06:06,560 --> 00:06:12,120
reference card also using GPU tweak was

83
00:06:09,960 --> 00:06:16,800
a fairly good experience I've never used it before at least not extensively but

84
00:06:15,199 --> 00:06:21,080
it does have some special features that allows it to work better with ASUS cards

85
00:06:19,160 --> 00:06:25,039
particularly the ones that use their custom vrm designs that are pretty

86
00:06:23,160 --> 00:06:29,919
different from all the other things that are out there on the market and with the

87
00:06:27,080 --> 00:06:34,160
integrated GPU Z utility as as well as the ability to set up monitoring as a

88
00:06:31,720 --> 00:06:39,639
widget it's pretty handy thanks for checking out my unboxing and first look

89
00:06:35,919 --> 00:06:41,199
