Help - First Time Overclock

[imported_adchac]

Hi, as u already know, I need help for my very first overclocking attempt. As you'll see i bought a "good overclocking system", but i feel some fear inside that keeps me away of do it without your advice.

This is my "new" system:
Intel Core 2 Duo E6400
ASUS P5W DH Deluxe
2x512 PC6400 Corsair Cas-4
2x250GB SATA Western Digital (RAID via Intel Matrix)
ATI Radeon X1900XT-256MB
Stock Cooling (upgrade in 10 days)
Artic Silver Ceramique
Antec Tower case with 3 80mm fans (1 in, 2 out)
Ambient Temp 20°C (-+3°C)
Stock CPU Temp : 33°C

Thanks in advance for your replies.

Follow the posted guide and you'll be golden.

With orthos blend running if your temps are below 55C (Measured with TAT which is linked above) after an hour you're fine. Some folks choose to run their systems up as high as 69C+, but i prefer to err on the side of caution. Run Orthos for 12 hours. If it doesn't get any errors, you've got a stable overclock.

My personal experience with the 6400:
Set the Core voltage to 1.375, FSB to 400. Set other options as in the posted guide.

System booted, but errored almost immediately in orthos blend. I ran the orthos CPU test, no immediate errors. Ran Orthos Mem test, errors.

So i cranked the Dimm voltage by .1 at a time until i got no more errors. Ended up at +.3 (2.1V)

Ran orthos blend for 12+ hours, no errors. Temps ~55C under load.

Cleaned up my case layout, made some extra holes for airflow. Dropped my temps down a few C.

On a tip from another post here, set my fsb to 401, and dropped Vcore to 1.325 Ran orthos again for 18 hours, no errors. Stable and my temps were around 45C under load. CPU-z however still reports my fsb at 400 though.

So 401 FSB worked and 400 didn't. Does the Gigabyte 965P-S3 have a northbridge strap?

Actually 400 was working at 1.375, and i dropped my voltage down to 1.325 at the same time as I changed to 401. Likely made no difference going to 401. I've since dropped my voltage down to 1.275 and FSB to 400 and i'm still stable.
