Hi... I know this is off topic, and I apologise, but you guys are just
so well informed I couldn't NOT ask in here.....and this pc will be
used as my main gaming rig, so Sims will be played on it, so its sort
of relevant....

Anyway my question...

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

Im not sure of the exact setting requires for that setup, but it varies
from component to component. Just because someone has got 3.0Ghz out of
their doesnt mean you will, and you mayve find you use different settings
to get similar speeds. I have my E4300 rated at 1.8Ghz running at 3.0Ghz
with the same HSF. Your CPU seems to be getting quite hot, is the HSF
attached correctly? I found mine to be a pain in the ass to fit and
secure properly... Also does the rest of the PC have adequate cooling,
an intake and exhaust fan on the case will help a lot.

What stress test are you running? If it runs for several hours without
crashing or showing errors I'm not sure the temprature is too much to
worry about... But don't take my word for it. :p
