An easy WC solution for beginners

Threaded View


I just built a Q6600 based PC with a very specific goal : online
chess-playing-programs competitions.

The needs were : as fast as possible and stable for long (several hours)
sessions at 100% processor load but no need at all for powerful graphics.

As it was my first PC building from scratch I initally went for air
cooling but could not get satisfying results with an Arctic square unit.

I then opted for a Corsair Nautilus 500 WC kit and this is the reason
why I post this today : this unit really makes wonder while being
incredibly easy to install : no need to take off the MB and complete
installation performed in 30 minutes (they say eight minutes but I did
it slowly and prudently).

With a little tuning I have the baby running extremely stable for hours
at full load under WinXP 64 at 3.500 Ghz.
I have my chess programs performing overnight chess games analysis at
100% processors load with the hottest core at 62C.
OCCT 30 minutes test is OK with 65C maximal temperature on the hottest
core.

I just thought this could be interesting fo those who hesitate to go on
water.
Another good point : the kit is really not that expensive (180 euros)

My config :

MB :      152     Gigabyte GA-P35T-DQ6
Proc :    212     Intel Core 2 Quad Q6600  G0 stepping
Paste :     5     Arctic silver 5
Cooler :  180     Corsair Nautilus 500 watercooling kit
Mem :     459     Corsair XMS3 2x1 Go DDR3-SDRAM-1333 PC3-10666
PSU :      61     Cooler Master eXtreme Power 600W
GPU :      42     NVIDIA GeForce 7300 GS
HDD :      96     Seagate Barracuda 500 Go 7200 RPM 16 Mo SATA II
DVD :      38     Pioneer DVR-112
Case :     60     Thermaltake Soprano VB1000SNSD
Fan :       7     Antec Tricool 120 replacing one of the case ones

Total:   1312 euros

So, the computer basically plays for you?

How much of an overclock did you manage on air?  Temperatures?

Quoted text here. Click to load it

Would that be around 389 x 9 or did you lower your multiplier?   Of course
you tested on all four cores with Orthos or equivalent?

Nice.  Is it quiet?

And is the application optimized for 4 cores?

Oh yes !

I just built my PC is for being able to do some parameters optimisation
related to "chess knowledge" but the real things with which competitions
are performed are 8 or 16 core ones.
For competitions at least three teams play remotely on experimental PCs
hosted in AMD or Intel labs.
Two years ago the program who won the world championship played on a 512
processors parallel machine. In 2006 the winner ran on a 16 processors
unit in Intel labs.
Those who do the programming of these experimental programs are real
experts in parallel programming.
For what regards myself I just assist in providing advices regarding
parametrisation of the "style" of play of one of these progs.

Yes. The experimental programs with which I play have lots of tunable
parameters modifying their style of play ... and their strength.

I could not go higher than 3.2 Ghz for sustained full load and then I
had the cores around 70-72C.

yes 389 * 9.

(I had it running easily at 420 * 9 but this required much higher
voltage and higher temps resulted. I am not interested in finding
maximal speed : I need stability for long-time running at full processor
load)

Other non-default parameters :
Latencies 10/10/9/24 (did not succeed in lowering that so far)
CPU voltage 1.494
DDR3 overvoltage +0.25
FSB overvoltage : +0.10
(G)MCH overvoltage +0.075

I test with OCCT, Everest test, Fritzmark benchmark ...
... and my chess programs.

No, not at all.

The cooling system is reasonably quiet.

But I have all sorts of noises seemingly coming from the MB itself (I
don't know the words in english : a kind of high tone whistle).

And unfortunately there is also a lot of noise coming from the PSU
ventilator (as if it was touching something). I have no way to open it.
Strangely enough the PSU is quiet when the PC is lying on its side but
as soon as I put the case up PSU noise comes back :-(

Any advice ?

Very cool.  Do you play with limits on how long you can consider a
move?
