Q6600 and P5Q mobo help

Yup, 1.55V. I have seen other posters using 1.6V+ on their 65nm Core 2 CPU's in order to obtain their desired Oc. The generally accepted max voltage for the 65nm generation on air is 1.5V. You can go higher but you will probably need better cooling to keep up with all the extra heat. Yes, my system is wattercooled. @ 3.6Ghz w/ 1.55V, I am around 65c with my hottest core in a torture test. Under real life usage, it rarely goes over 55c.

The longevity of the CPU is really dependent on all of those when taken to the extreme. Higher voltage causes higher heat and electron migration. High temps and high deltas between idle and load temps puts extra stress on the entire package. With this all in mind, running a high overclock will lower the lifespan of your CPU. Probably from 10 years at stock to 4 or 5 years overclocked. They will rarely fail before it is time to upgrade as long as you keep them within their thermal specs (max 75c would be recommended).

If you are 100% stable at 3.6Ghz and your CPU only loads to 73c with stress testing, you will be just fine. Stress testing your CPU puts an artificially high load on your system (unless you are in the professional sector where you would not be overclocking) and, as such, represents your worst case temps. In day to day operation, I would expect it to max out in the mid to upper 60's.

man thats still gonna be some hardcore stuff hahaha

now i get why ppl risk water cooling or lapping to reduce temperature
😛

but overclocking is such an art
before i was struggling to run 333 * 9 with 1.28v
and now
thanks to Lupi
all i did was turn on Line in Calibration
and its giving me no problem for 2 min running 354 * 9 with 1.28v

My Q6600 must be very similar to yours.
100% prime95 stable @ 3.0ghz with only 1.285V.
Same VID to.
Never tried for any intermediate Oc's, went straight from 2.4 => 3.0 => 3.6.

Not so much of a risk with wattercooling.
Just make sure to test the loop overnight before you install any of your components.
Lapping, on the other hand, can get a little harry.
Not a real hard procedure but some people still manage to damage their chips in the process.
Still, it is an easy way to gain 2-4c on your temps...

If you want to keep this system stable for as long as possible...
Find what settings net you a stable 3.6Ghz and, as long as the temps are fine, save it as an Oc profile in your BIOS. Leave it at 3.x Ghz, stock voltage, until you feel like playing a game. Reboot and switch on the Oc. Works like a charm!

My sister came in b/c she smelled burning....(bad?)


made some more tests and these were my experiments
pretty sure im gonna let it run at 354 * 9 (3.18GHz) at 1.28v
can you suggest me a good voltage for the North Bridge and the South bridge??
😛

If you are not going over 400Mhz FSB, I would leave it on auto.
ASUS' BIOS has settings pre-programed up to that point.

Not a bad overclock.
If you want to keep it in that area, I have a further recommendation. Change it to 400 * 8 and put the RAM at a 1:1 ratio.

Even with DDR2 1066, you will have better performance running 1:1 with lowered timings. Reason being the RAM has to use your FSB to shuffle data around. Even if it is trying to push data through at 533Mhz (it is DDR RAM so it is actually 1/2 the listed speed), you will still be pushing it through at 266Mhz, 333Mhz, 354Mhz or what ever you have your FSB set at. If you can push it through at the buses maximum rate with lower latency, you will obtain your optimal performance.

i think the multiplier on my q6600 is locked to 9 though
do you know how to change it?

 

[Lupiron]

It is unlocked from x6, to x9.

There are two areas to change it, AI tweaker/ Ratio setting, And then under advanced CPU settings has the other one. Change them both to your desired Multiplier!
