Hi...

During the last couple of days I have just built myself a nice new Intel Core 2 Duo
E6600 based pc, and I have it working great, but I would like clarification of the
settings needed to overclock the pc.

I have already got the cpu to 2.7Ghz using 9x multiplier and 300 FSB (stock setting
is 9 x 272 = 2.4Ghz) and have tested it ok (using Sandra Lite, and CPU Stress
Tester) and the max temp for the cpu never goes above 50 degrees C.

Then I tried using 8 x multiplier with 350 FSB = 2.8Ghz and the pc also worked great
(tested again with Sandra and CPU Stress Tester) and temp never got above 51
degrees C.

However, CPU-Z and Sandra Lite and Speedfan all report the cpu speed as 3.1Ghz
using these settings from the bios?

Now I know that this is a very new M/B and therefore some programs may not be
reporting the speeds / settings correctly, so I just wanted to clarify what settings
other overclockers are using?

I've read many reports that this sort of set-up should easily get over 3Ghz speeds.
But what settings should I set in the bios, specifically for the cpu multiplier? the FSB?
the memory (so far I have NOT changed any memory settings) and the DRam spec?
and the core voltage? (so far I have not cahnged any voltages).

NB: It looks like this M/B uses a 2:3 ratio for the cpu:Dram (eg: cpu clock = 300, so
DRam = 300 / 2 = 150 x 3 = 450) and this is the bit thats confusing me, I think my
Ram is rated at DDR2 800Mhz (400 x 2 ) so how come its running at faster than 400?

Any info and advice would be welcomed..... thanx

The complete PC spec is as follows:

Intel Core 2 Duo E6600 cpu (4Mb cache)
Arctic Cooling Pro 7 fan and heatsink (also used arctic silver thermal compound)
Abit AB9 Pro (WiFi) M/B
2 x Gb crucial Ballistix DDR2 ram ( 2 x 1Gb chips running in dual channel mode)
Nvidia 8800GTS graphics card (320Mb)
Arctic 600w (modular) PSU
Hitachi Deskstar 320Gb SATA H/D
LG SATA DVD/CD writer
LG 19" TFT (widescreen)
Sony 1.44Mb FDD

What does the C1E function on this M/B do? (it is set to auto by
default, but it can be disabled).

Also, what does the thermal control bit of the bios do on this M/B? eg:
should I have it enabled or disabled? (its enabled by default).

Thanx

Thanx for the info Len.

Out of interest how hot is your cpu getting when clocked? mine never
seems to go above 50 (51 max under load and around 30 at idle) but not
sure if this is good or bad? I thought the max temp for this cpu is 65,
so if I'm only getting to 50 then I thought that was ok.

Thanx

Thanx, I'll give it a try tomorrow and see how it goes, once again thanx

" Each CPU should have the same temperature."

Are you sure about that, Phil? In Intel's "TAT" and other programs, my PCU
0 is always about 4 or 5 degrees higher than CPU 1. It doesn't matter if I'm
OCd or not.

For my E4300 the two CPU cores have the same temperature for the TAT
processor 100% load and for the Orthos small FFTs 100% load (within
round-off error for the TAT temperature display.) What are the differing
temperatures and under what loads? Have you checked the thermal compound
application?

No problem with temps. It runs cool ... lower 30s when not overclocked. It
just always has a temperature difference of 3-6 degrees, depending on the
CPU being under load or not and how much overclocked.

Just ran across this at the EVGA forum. It talks about core 2 duo temps. I
guess the two cores are usually different. It also says that the Intel "TAT"
program is the stress test to use.

I tend to distrust postings that have a high word to number ratio.

For my E4300 / EVGA 680i motherboard system with the E4300 at 2.7 GHz and
1.2500 v set, 1.21 reported and memory at 1:2 CPU Clock : Memory Clock ratio
(memory at DDR2-1200 MHz) and Intel stock boxed retail heatsink fan with 23
C room ambient
I get the following temperature readings (from TAT.)

Orthos small FFTs: CPU 0 rises from 40 C to 61 C
CPU 1 rises from 40 C to 61 C
the temperature difference between the two CPUs is never more than the
roundoff error (+/- 1 for each) except when the velocity of change is high.

TAT 100%: CPU 0 rises from 40 C to 69 C
TAT 100%: CPU 1 rises from 40 C to 69 C
the temperature difference between the two CPUs is never more than the
roundoff error (+/- 1 for each) except when the velocity of change is high.

An important difference between the TAT stress test and the Orthos stress
test is that the Orthos stress test checks the results of computations, and
will halt on incorrect results. I think that makes it more useful as a
stability test that the stress test in TAT.

I get the above numbers with the polling interval for TAT set to 2000 ms.

One possibility for the different results see is that TAT is designed for
mobile versions of the Core 2 Duo and runs a different stress test according
to which version is detected (Yonah or Merom.) Your figures are from a 4
MByte L2 cache Core 2 Duo while mine are from a 2 MByte L2 cache Core 2 Duo.

One more possibility, you can start both CPUs at the same time by using the
'Start Monitor' button at the lower right hand corner of the TAT page.
