im using:Gigabyte GA-965P-DS3(F5_bios)...Intel Core 2 Duo E6400...Stock Intel cooler...2GB Corsair DDR2 XMS2-6400C5 TwinX...7900 GTO...
...Antec True power 550wPSU...Windows XP-sp2...
i have overclocked my processor to 2.60ghz (CPU Host Freq. 325mhz, memory multiplyer 2.50, memory running at 815mhz, at 5,5,5,12. PCI Express freq @100 )
I have set Fan speed control to LEGACY to keep noise down!
and the CPU is idling @ 51c (which im a bit worried about)
With fan set to full it idles @ 46-47c

firstly, i am checking temp thru bios, what is the best temp programme, (preferably a small inobtrusive prog.)so i can check temps under stress-load.

secondly, is there any way to reduce temp, (or is this temp 51c@idle quite safe for CPU) i have read you can lower voltage on these CPUs and they still run OK? (i would prefer to keep stock cooler rather than messing around fitting new cooler)

it is currently running very stable, in fact i have had it running stable at over 3.00ghz with same voltage, just higher CPU Host freq, but Temp is higher!

also is there any other bios tweaks i can make for overclocking, ie, voltage, memory settings etc
upto now all i have done is change CPU Host Freq,(@325mhz) PCI Express Freq,(@100mhz) system memory multiplyer(@2.50), memory timings (@5,5,5,12), and disabled throtling functions-CPU enhanced halt, CPU thermal monitor 2, CPU EIST function.
and GPU is running at (core 670mhz memory 1.45ghz=725mhz!)

cheers
 
Change mem multiplier to 2.00, set FSB to 400, put +0.1V through chipset (just incase).

That'll give you a 3.2Ghz clock, your mem will be runnin @ stock so won't be a problem.

Give it some stability testing, if its not stable add 0.025V to the vcore and test again, move up in 0.025V steps until you get it stable, then start backing the vcore down in single increments until it fails, then put it back up a knotch.

As long as you are under 60C load I wouldn't be worried about your temps.

Unfortunatly the stock intel cooler is pretty crappy, so either you crank the fan up, or you buy a new cooler. I just got the el-cheepo Freezer7Pro and its keeping my 6300 @ 56C load @ 1.425V @ 3.33Ghz :)
 
you said: put +0.1V through chipset (just incase).
on the GA-965P-DS3 would i increase chipset voltage using MCH Overvoltage Control? or is there another control ?
i know there is cpu voltage control what you mentioned?
(Im a bit new to this overclocking lark you know)
oh and im gonna get a Arctic Cooling Freezer 7 Pro CPU Cooler it looks pretty easy to install ???
cheers
 
Yup MCH is the chipset.

Use Intel Thermal Analysis Tool (TAT) for core temps, i find that running stress through that kicks out more heat than say orthos. But i mainly use orthos for stress testing stability etc.

I have my E6400 @ 3.2, I'm sure it will do 3.4-3.6 i just don't need the extra umpf right now. :p
 
with good cooling, you should be able to hit 470 or 480 FSB most likely.
that would give you 3.7GHz running close to or slightly above stock CPU Volts, with good air cooling ( Scythe Ninja'ish )
your 6400C5 memory should be able to maintain 5-5-5-15 timings at RAM +0.3V (2.1V) upto 960MHz ( my 5300C4 does C5 at that speed and voltage )
also, i find ensuring you set Robust Graphics Booster to Fast helps.
You might need +1v on FSB also.

Disable Legacy Storage and the various Thermal / Virtualisation features.
