Overclocked E6600 & P5W DH Deluxe with Incredible Results
I just overclocked my new "rig:" E6600 @ 3.2GHz (2.4GHz), P5W DH
Deluxe, Corsair XMS CL4 RAM: 2 X 1GB DIMMs & 2 X 512MB DIMMs PC2 5700
(6400) Dual-channel interleaved, etc. (Note: I just use the stock
HSF and I also mounted the included optional fan on the passive
radiator fins.)
What's incredible is how simple the 33% overclock of the E6600 & P5W
DH Deluxe was.
I read several posts and here's what I did based upon discussions in
these newsgroups:
2.4GHz (stock) - I first ran two instances of a software program I
have that utilizes each core 100%. (One instance for each core.) It
took 11 minutes and 10 seconds. The CPU temp went from 24C to 34C and
held steady.
3.0GHz - Then I went into BIOS and manually set the FSB frequency to
333MHz, the DRAM frequency to 667MHz, and the RAM voltage to 2.1V
(spec'ed) and the timings to 4-4-4-12 (spec'ed) and I guessed for the
2T parameter. I again ran the two instances of the program with both
cores at 100%. This time it took 8:58 to complete. The temps went
from 24C to 38C and held steady.
3.2GHz - For the next overclock I only raised the FSB clock to 356MHz
which automatically raised the DRAM frequency to 712MHz. I again ran
the two instances of the program with both cores at 100%. This time
it took 8:18 to complete. The temps went from 24C to 42C and held
steady.
4.0GHz - The last attempt at overclocking failed when I raised the
FSB frequency to 400MHz. I tried fiddling around with it. I finally
did get to the Windows opening screen but it took a vCore of 1.45,
etc. and still crashed. I figure at these higher voltages I best have
industrial cooling which I do not intend to get into. And 1.45 vCore
is well outside of Intel specs. And these higher settings probably
would shorten the life of my system.
So I said, "enough."
But think about this: I did not change anything else. All other
settings were left at default. And all with air cooling.
This is testament to what a great buy the Intel E6600 and the Asus P5W
DH Deluxe are. Just incredible!

The most interesting part is that your temperatures remain so low with the
stock Intel HSF.
Unless Intel includes a vastly superior HSF to that supplied with the 6420,
the results are nothing short of incredible.
My 6420, overclocked to 2.72 GHz (from 2.13), runs at 42-43C at idle to low
60's under 100% load on each core. |

Very good.
Have you tried 'Orthos' and 'TAT' to check for stability under load, and
(with 'TAT') for the two individual core temperatures? These two utilities
could give you a better idea of what is going on.
You might also try LOWERING the CPU core voltage. My E4300 @ 2.7 GHz runs
with a core voltage of 1.21 v, more than 0.1 v below the stock setting.
Even then with the Intel stock retail, boxed heatsink/fan 'TAT' reports CPU
temperatures in the 60's C when both CPUs are loaded 100%. (room ambient ~
28 C.) With a LOWER CPU voltage you might get an even higher overclock with
stock cooling.

Yep, I have been running my E6600, at 3.24 ghz, on EVGA 680i mb for about 5
months now, very happy with it.

very good OC..........but I am really amazed at your temps.
On my Gigabyte N650SLI-DS4 running with a FSB 400 and the mem @ 400x2 equals
a setting of 8x400=3200 on a E6420 with stock cooler........its hot than
hell here now reached 32celsius today.The computer is in a basement office
and shows an internal case temp of 30celsius.At Idle both cores show a temp
of 32 to 35 Celsius using RightMark CPU Clock Utility and when I run Orthos
it goes up pretty fast and reaches 58-60 after a 1/2 hour running at 100%.At
that point it remains pretty stable temp wise for the next 1/2 hour and then
goes up to63- 65celsius at which point I stop the test.
Ordered myself a Thermalright Heatsink the HR-01 with a 120mm Fan and a Fan
Duct to connect to the 120mm case fan in the back.
lets see if that will cool things down a bit.
i have a temp probe on that massive northbridge heatsink and it normally
runs at 65 and reaches 73 under full load.Still trying to find a way to cool
that thing down some.

Your temperatures are much more in line with my experience with an E4300 @
2.7 GHz / 1.21 v core (28 C ambient / mid-60s C with TAT 100% on both CPUs.)
Orthos shows a temperature about 5 C lower.
I put the difference down to the temperature reporting application.

Here I am again with another question 
When I saw your post, I went to check the voltage for my 6420 at 2.72 GHz
(Auto in the BIOS), and discovered through both Asus Probe and SpeedFan that
I was running at ~1.42v. That sounded a bit high for "Auto", so I changed it
to 1.35 in the BIOS with no perceivable result except a welcome 2C reduction
in operating temperature in normal use.
I then went to the Intel web site to see what the "normal" or default
voltage for a 6420 should be. Got mired down in page after page of details,
but didn't find what I was looking for. Do you, by chance, have a link? >> Stay informed about: Overclocked E6600 & P5W DH Deluxe with Incredible Results |

I had to RMA my P5N32-E-SLI because of a SATA controller failure.
Before I had the problem, my temps (liquid cooling) had dropped
significantly from 29c/idle and 51c/max running Orthos small ffts to 27c
and 43-44c max. I was able to get the e6600 up to 3.3 quite easily but
then the SATA controller just failed to recognize any drives at all.
Default bios settings showed no difference. MB temps were fine at 41c
pretty steady after adding a 100mm fan to blow across the MB heat pipes.
My replacement will be a Striker Extreme due to no P5N32s were available
Mon except in the 650i version. I am not familiar with the Striker
board, but will give it a go since it is also a NV 680i board. The
customer service guy said it is a new, boxed board so I don't think I
will be worried about it being a refurb.
I generally have used CoreTemp to monitor my temps on the C2Ds since
it seems to reflect pretty much the same temps as the bios and I could
compare with others here that use the same app. Temps have always been
an issue with folks using different software. The OP's temps were very
good for that OC and air cooling.

When overclocking you should use the lowest possible voltage the give a
stable overclock. Trade-off among core voltage, CPU speed, and CPU
temperature for the best stable overclock.
The CPU core voltage can be different among CPUs of the same type and
identification - it is set durning testing at the factory.
"Individual processor VID values may be calibrated during manufacturing such
that two
devices at the same core speed may have different default VID settings. This

Thanks very much, Phil.
I had no idea it was so complicated. I guess the reading from the BIOS Auto
setting was legit.
So far 1.35 is working fine (down from 1.42). I'll try a little less the
next time I restart. >> Stay informed about: Overclocked E6600 & P5W DH Deluxe with Incredible Results |

The new Intels are kind of different animals. I believe the actual
default core is something like 1.20-1.25v. I have just recently found
that when overclocking using 'Auto' for voltage that my 680i board will
give whatever voltage it thinks should keep it stable to the CPU. At
3.3ghz, the core voltage for my e6600 was set to 1.45v. I manually set
the voltage back down to 1.30v and it stayed stable.

Again, I owe you and Phil a huge THANK YOU for the insights into C2D
overclocking. With my VCore now reduced to 1.30 in the BIOS, I'm running in
the low to mid 40's C in normal use at 2.8 GHz, still using the Intel HSF.
I've run Orthos for over three hours and the CPU never exceeded 61C.
I'm very pleased with the results, especially as the PC seems 100% stable. >> Stay informed about: Overclocked E6600 & P5W DH Deluxe with Incredible Results |

The temperature monitoring program CoreTemp will tell you what voltage
is specified by your processor. It is shown in the field labeled "VID."
http://www.alcpu.com/CoreTemp/
I'd be interested to know what is your default voltage on the E6420. >> Stay informed about: Overclocked E6600 & P5W DH Deluxe with Incredible Results |

Sorry, but I don't know the default voltage at stock speed, as I left it on
Auto until I read Phil's and Ed's articles earlier in this thread. After
reading Ed and Phil, I had a look using SpeedFan and found it to be 1.42v
when I was over clocked to 2.72 GHz. Phil and Ed agree that these C2D's
adjust themselves to over clocking by upping the voltage. I set mine to 1.3v
and suffered no ill effects. The CPU is now at 2.8 GHz and runs measurably
cooler that it did at 1.42v. >> Stay informed about: Overclocked E6600 & P5W DH Deluxe with Incredible Results |

'Core Temp 0.95 reads the factory set default core voltage on the CPU (the
voltage setting code that appears on the VID pins of the CPU that the
motherboard uses to set the voltage regulator output.) Just download and
run the applet to get the factory default voltage setting.
Some motherboards have automatic overclocking features that will override
the VID and change the CPU voltage unless this automatic CPU voltage feature
is disabled in the BIOS. That is the case with the nVidia 680i motherboards
that 'Ed Medlin' and I use. For example, the factory set core voltage for
my E4300 is 1.3250 volts. I've found that the best setting for overclocking
is 1.2500 volts. The various monitoring programs that work for my
motherboard report an actual core voltage reading of 1.21 volts when I set
it manually in the BIOS to 1.2500 v.
I still have not found ANY monitoring programs that correctly report all of
the voltages, temperatures, and fan speeds for my EVGA 680i motherboard.
Even monitoring programs that recognize the Winbond W83627DHG do not report
all the voltages correctly or all the temperatures correctly or all the fan
speeds correctly. One problem with the voltages (and, I suppose, with the
temperatures) is the particular divider resistors the motherboard
manufacturer uses - the temperature conversion software software must not
only know about the particular monitoring chip used, but also the resistor
divider ratios.
