Project: Virgin Enthusiast Build

deejay u defo have the serial block on your cards my 470's are either the same temp or only 1c differance on load or idle
 
Yeah, I ordered the serial :) just wondering whether I should have ordered parallel.

100 during furmark, yeah. Doesn't go above 75 during gaming mind. It's because I am running my pumps and fans so slow ;)

That's with both 480s overvolted also.
 
thx for comments.

am running latest bios, makes no difference.

definately sending PSU back when i have the energy, its ridicuously loud
 
I have the Corsair 1000W PSU - seems pretty decent, not too noisy.

Noisiest thing in my PC is my 4870x2 graphics card, as soon as I can get a newer model for a decent price I am going to do so, just because I like to keep my PC running as quietly as possible.

I also gave up overclocking by any real degree, I hate having stability problems and tbh the i7 920 I have in there now runs really well anyway, currently have it clocked to 2.8GHZ which equates to 3GHZ when the speed step kicks in :)

Finally got round to taking some decent measurements!!!

the 50Hz is normal, so that can be ignored.

the 125Hz is a bit odd, I can only imagine that even with the power to the PC off, there is some sort of power going through. the mobo certainly has power, so maybe some form of electrical noise. not really bothered by that though.

the problem is the damn mid and high frequencies above 125HZ!!!!!

my fans are all fixed except in the PSU which is obviously temp controlled.

even at idle, the noise from the PSU is quite clearly the major noise source, subjectively. at load, there is no question about the noise from the PSU, something these measurements demonstrate (remembering that all other fans are fixed speed and very quiet)

for this test, I have air ducted in from outside my case directly into the PSU intake fan. the air going in is cold to the tough when putting my hand in the intake duct. the air coming out of the PSU is barely warm to touch. as a guide, the air coming out at load feels less warm than my media server!!! so I can only conclude that the PSU isnt getting pushed that hard.

this makes sense as the PC only draws about 800W from the wall with both GFX cards and CPU loaded up to 100% (using Kombuster multi-gpu extreme burn mode and prime95 multithreaded).

BeQuiet quote 20dB to 30dB at idle/load respectively.

I have sent them an email (again!) with the results of this testing, and have heard nothing.

I shall be ringing OcUK up about this, as hopefully they will get more luck with sorting the problem out (and hopefully a working replacement) than I have had to date....
 
Single figure values:


Background Average 20dB LAeq (NR18)
Idle Average 31dB LAeq (NR25)
Load Average 41dB LAeq (NR38)

Taken at about 1m from the PC case, where my head would normally be in a small living room
 
Ordered a parallel EK link to replace the serial link for my gfx cards. This will let me put some decent overclocks on those I hope.

Also ordered an EK full cover block for the UD7 mobo. Should bring the case temps down a bit and allow me to go for some higher CPU overclocks.

Will fit this all (with nice pix of course!) once I have finally got round to sending the PSU back to OCUK.

Aroogah! :D
 
finally got the SSD working on the sata3 port!

running bios F8e which updated the firmware on the gigabyte x58 ud7. have updated firmware on the crucial c300 to v0006. not sure which drivers to go for, have tried windows and intel, but settled on the intel RTS drivers for the sata/achi.

SSD on sata2 port:

and on the sata3 port:

and its been stable like this for 24 hours running all sorts of benchies and games, so am reasonably happy with the ssd now.

the latency does seem to have increased now though. only marginally but apps dont open as snapily as they used to i dont think...
 
Pushed the cpu to 4.41GHz. voltages starting to get a bit bonkers now!

gfx still at stock, and mobo waterblock sitting on desk waiting to be installed ;) oh, and PSU STILL to go back for RMA!

Furmark = 38500

Heaven score = 2528
fps 100.4
min 61 (odd, as it never visually went below 80)
max 213

cpu temps were generally 65 to 70 degrees C.
gfx 1 maxed out at 54 degrees C.
gfx2 maxed out at 70 degrees C.

pumps still at speed 1 and all fans set at minimum RPM, so plenty headroom on the temps, but the whole point of this build is quiet ;)

looking forward to changing the gfx link from serial to parallel, should bring both gfx cards to about 60 degrees C under full load, which means I have LOADS of headroom for overclocking the nuts out of them :d

whoop :)
 
I hope one day to be of such dedication and enthusiam that I might spend more on my PC than on say... a car, or a flat :p Really though I have nothing against enthusiast builds, I simply can't afford them, being a 20 year old student and all.
But I must admit, I have become somewhat addicted to benchmarks and performance comparison... at the start of term I was down at Bar3One getting drunk and grind dancing girls D: What has become of me?
 
Haha! Quality mate :)
I'm a boring 32 year old now so never go out and just sit in every night stroking my PC ;)

Couldn't keep me in when I was a 20 year old student mind! Now get off this forum, get back to the bar and grind up against more fit, taught, pert hotties before things start getting wobbly!

Merry Xmas :)
