1
00:00:00,440 --> 00:00:08,920
well the Rampage 3 Extreme is running now but I wish I had sort of a more

2
00:00:05,960 --> 00:00:13,040
conclusive uh I wish I had something more conclusive as to what exactly was

3
00:00:11,120 --> 00:00:17,760
causing the problem because there okay there's a couple things I ran into first

4
00:00:15,040 --> 00:00:22,400
of all I couldn't get it to post until I removed the 980x that was in there I put

5
00:00:20,760 --> 00:00:30,640
in this Kingston RAM although I haven't tried any other RAM yet and I removed uh

6
00:00:25,880 --> 00:00:32,360
my GTX 26 or rather GTX 8800 GTS 64

7
00:00:30,640 --> 00:00:36,360
video card which now I've tried on another system and it seems to be dead

8
00:00:34,680 --> 00:00:41,719
which is very confusing because it was working up until exactly when I tried to

9
00:00:39,200 --> 00:00:45,960
use it with this system so that's part of why I ran into trouble it's uh really

10
00:00:44,039 --> 00:00:50,559
bad when your tester Parts your your known good components die so anyway I

11
00:00:48,079 --> 00:00:56,559
tried with this GTX 275 that's sitting here and it worked and then I tried with

12
00:00:53,320 --> 00:00:58,680
uh with an evaluation um Radeon 5000

13
00:00:56,559 --> 00:01:04,000
series card and it's working with that as well so we're finally posted into the

14
00:01:01,160 --> 00:01:08,159
BIOS but since the whole point of my original video with the Rampage 3

15
00:01:05,720 --> 00:01:13,119
Extreme was going to be seeing how it reacts with 24 gigs of RAM I thought

16
00:01:10,600 --> 00:01:18,360
before I go any further what I'll do is I'll pull out this Kingston module and

17
00:01:15,680 --> 00:01:22,320
then I will see what happens now that we've actually got the board posting

18
00:01:20,320 --> 00:01:29,560
because we've got a working video card in it I'm going to go ahead and install

19
00:01:24,560 --> 00:01:30,880
my six RAM dims okay we got one this is

20
00:01:29,560 --> 00:01:35,200
going to take take a little while so please bear with me just got the camera

21
00:01:32,759 --> 00:01:42,439
sort of hanging from my neck here I've had some complaints that it causes

22
00:01:37,880 --> 00:01:44,280
dizziness and nausea so um I guess I can

23
00:01:42,439 --> 00:01:50,880
I'll have to disclaim my show from now on that uh watching it may cause you

24
00:01:47,600 --> 00:01:53,040
know vomiting and all those other nasty

25
00:01:50,880 --> 00:01:58,280
pharmaceutical side effects it's okay you guys can handle it

26
00:01:56,079 --> 00:02:01,799
all right there we go so I got my six dims in there it looks all shiny and

27
00:02:00,280 --> 00:02:05,479
gold okay the color scheme doesn't really match but uh that's okay if

28
00:02:04,240 --> 00:02:12,720
you're buying this motherboard you should probably be buying like some Reapers or uh or Platinum Series RAM

29
00:02:09,560 --> 00:02:14,800
anyway rather than the basic gold so

30
00:02:12,720 --> 00:02:19,000
here the little post LEDs this is what actually helped me figure out it was the

31
00:02:16,319 --> 00:02:24,120
VGA card so you can see it goes CPU RAM VGA boot device boom we are booted up

32
00:02:22,400 --> 00:02:29,319
and let's see what it def detects by default for the RAM settings here so

33
00:02:26,400 --> 00:02:34,160
Target Dam frequency 1333 so it got there by default uh let me see oh okay

34
00:02:32,319 --> 00:02:38,519
extreme tweaker is the first option in this board go figure they assume someone

35
00:02:36,480 --> 00:02:44,080
buying a rampage 3 Extreme board is going to want to tweak it a little bit

36
00:02:40,720 --> 00:02:46,599
wow okay so Auto is 1333 we can set it

37
00:02:44,080 --> 00:02:51,000
up to, 1600 although I have no idea what would happen if we did that it looks

38
00:02:48,879 --> 00:02:56,159
like the default voltage for the RAM is going to be 1.5 volts and you know what

39
00:02:54,000 --> 00:03:00,599
since we're you know here anyway why don't we boot up the system and see if

40
00:02:58,519 --> 00:03:07,640
it's actually even remote stable with 1.5 Vols because this ocz RAM is

41
00:03:03,760 --> 00:03:10,400
actually rated for 1.65 Vols at DDR3

42
00:03:07,640 --> 00:03:14,560
1333 CL 99920 so what that could mean is maybe

43
00:03:12,640 --> 00:03:20,040
we could even overclock these modules a little bit and uh and and still run them

44
00:03:18,280 --> 00:03:24,959
within their default voltage so that would be kind of cool so I'm just going

45
00:03:22,519 --> 00:03:28,360
to wait for the system to boot up here let me see if there's anything else

46
00:03:26,120 --> 00:03:34,000
interesting on my desk ooh check this out it's a magne cores but it's not a

47
00:03:32,159 --> 00:03:38,640
real one it's actually just a just a blank just to to demonstrate how large

48
00:03:36,400 --> 00:03:43,400
the CPU is let me see if I have anything else around here to show for for context

49
00:03:41,200 --> 00:03:49,599
I guess I don't really but uh yeah it's really big there I'll kind of put it

50
00:03:45,760 --> 00:03:51,080
there so now you can see how big it is

51
00:03:49,599 --> 00:03:55,159
compared to a memory module okay we're boot it up there we go now I can stop

52
00:03:52,720 --> 00:03:59,120
killing time so here we go why don't we grab Prime 95 you always want to use

53
00:03:56,879 --> 00:04:04,439
blend when you're testing RAM because otherwise it doesn't really test the RAM

54
00:04:01,640 --> 00:04:09,519
and uh let's have a look at our task manager here where it will show our

55
00:04:07,239 --> 00:04:15,919
physical memory total of well that doesn't seem right let's

56
00:04:12,280 --> 00:04:18,680
fire up CPU Zs here and see what's going

57
00:04:15,919 --> 00:04:23,840
on so hold on available free it's only showing 16 gigs of

58
00:04:21,000 --> 00:04:31,360
RAM is that a Windows limitation okay first let's check here

59
00:04:26,440 --> 00:04:32,720
so in CPU Z it shows 24 4 GB of memory

60
00:04:31,360 --> 00:04:39,000
and it shows that it is running at the correct timings except this should probably be 20 but that has almost zero

61
00:04:36,520 --> 00:04:43,800
impact on performance anyway the Tas so I wouldn't worry too much about that and

62
00:04:41,280 --> 00:04:49,600
then uh okay our CPU frequency is correct everything looks hunky dory

63
00:04:47,199 --> 00:04:54,600
except for the fact that the RAM here is only detecting a 16 gigs so you know

64
00:04:52,160 --> 00:04:59,800
what it may actually be a bio setting uh this is not something I've done before

65
00:04:56,400 --> 00:05:04,479
running 20 gigs of RAM so here or 24

66
00:04:59,800 --> 00:05:09,120
gigs of RAM rather so here let's see um

67
00:05:04,479 --> 00:05:09,120
Windows 7 memory

68
00:05:09,160 --> 00:05:15,960
limits search is always your friend when you're troubleshooting

69
00:05:13,440 --> 00:05:19,560
something Windows 7 memory limits here we

70
00:05:16,880 --> 00:05:25,680
go so let's find out what Windows 7 Ultimate is limited to Windows Vista

71
00:05:23,240 --> 00:05:32,039
Windows Vista Windows 7 Windows 7 Ultimate okay should in theory be

72
00:05:27,919 --> 00:05:34,360
limited to 19 2 gigs of RAM but is it

73
00:05:32,039 --> 00:05:39,360
possible that there's uh something else at play here you know I had really hoped

74
00:05:37,280 --> 00:05:43,639
that this video would be more conclusive than all of this but

75
00:05:41,240 --> 00:05:48,520
um why don't we go back into the BIOS and see if there's any kind of setting

76
00:05:46,080 --> 00:05:54,199
that might obviously allow us to see all 24 gigs of RAM because you can see it is

77
00:05:51,560 --> 00:06:00,080
detected in CPU Z it's just a matter of the OS not being able to uh utilize

78
00:05:57,759 --> 00:06:04,840
it you see that all the time if you're running like a 32-bit operating system

79
00:06:02,000 --> 00:06:09,479
you'll see 4 gigs within um memory detection programs but you won't

80
00:06:06,319 --> 00:06:12,639
actually see 4 gigs of addressable

81
00:06:09,479 --> 00:06:14,479
memory space through Windows so okay

82
00:06:12,639 --> 00:06:20,360
here we go okay that's just

83
00:06:16,800 --> 00:06:22,880
frequency memory configuration protect

84
00:06:20,360 --> 00:06:27,639
allows you to lock or unlock the memory configuration well why don't

85
00:06:24,800 --> 00:06:32,599
we okay why don't we just kind of leave that the way it is in here here I don't

86
00:06:30,080 --> 00:06:38,639
see anything that looks like it pertains to

87
00:06:34,360 --> 00:06:42,199
uh H some kind of memory

88
00:06:38,639 --> 00:06:44,479
limit okay voltages are all

89
00:06:42,199 --> 00:06:50,120
good let's see if there's anything in advanc under maybe chipset or CPU which

90
00:06:47,080 --> 00:06:51,800
is where you more often find um extra

91
00:06:50,120 --> 00:06:57,879
memory settings these days because the memory controllers are on the CPUs on

92
00:06:54,440 --> 00:06:57,879
both Intel and AMD

93
00:06:58,319 --> 00:07:04,520
platforms hm

94
00:07:01,319 --> 00:07:07,560
all right well it looks like I am foiled

95
00:07:04,520 --> 00:07:10,720
yet again so once again please feel free

96
00:07:07,560 --> 00:07:12,919
to leave a comment and uh let me know if

97
00:07:10,720 --> 00:07:17,120
you can think of a way for me to get access to all 24 gigs of memory and I

98
00:07:15,400 --> 00:07:20,400
just wanted to address a couple of the ideas that other people had when I was

99
00:07:19,000 --> 00:07:24,560
trying to troubleshoot posting this board uh no I did not turn off the PCI

100
00:07:22,919 --> 00:07:30,240
Express slot although that would have been hilarious and sounds like exactly

101
00:07:27,039 --> 00:07:33,199
the kind of thing I would do um

102
00:07:30,240 --> 00:07:37,080
the problem did not end up being that I had to have a Molex plug here and here

103
00:07:35,319 --> 00:07:41,960
and I even tried with a higher powered graphics card that 275 Co-op and that

104
00:07:39,479 --> 00:07:45,800
did not fix the problem uh the problem was not clearing the

105
00:07:43,319 --> 00:07:50,400
simos um and it was not flashing the BIOS I did not need to flash the BIOS to

106
00:07:47,800 --> 00:07:54,400
get the six core working again in here and uh let me see what some of the other

107
00:07:52,479 --> 00:07:58,560
some of the other good ideas were and uh yeah no you know what I

108
00:07:57,080 --> 00:08:04,000
actually had a lot of good comments a lot of good ideas but but none of them ended up being it it ended up being a

109
00:08:01,960 --> 00:08:08,919
dead video card which is strange because I did already test with the GTX

110
00:08:06,360 --> 00:08:14,080
260 and um yeah I didn't didn't have any luck on

111
00:08:11,879 --> 00:08:18,159
that side either so you know it might be a matter of going home and testing my

112
00:08:15,720 --> 00:08:22,199
GTX 260 now as well to see if maybe that's fried too that would be just

113
00:08:20,680 --> 00:08:32,879
terrible luck so thank you for checking out my video on installing 24 gigs of

114
00:08:25,759 --> 00:08:32,879
RAM in the assus Rampage 3 extreme
