Q6600 Overcloking - Are these figures safe?

Hi

I like my computing to be simple these days. I don't mess around with hardware that much. I have a box I built myself that runs OSX.

One thing I do try and keep an eye on is temperatures. I do want my hardware to last as long as possible.

I just bought a new case for my rig - a Silverstone FT02. It has a pretty good cooling system in it. I don't want to be messing around with water cooling. I do like a very quiet computer though. Fan noise annoys me. Spec of system is as follows :

FT02 Case
Q6600 2.4GHZ with an Akasa Freedom Tower Heatsink and the fan it came installed with.
4GB Corsair memory
3 hard drives
9800gtx+

The CPU, GFX and outlet 120mm fan are all on low voltage. Think they spin around 800rpm. Then the 3 huge fans in the base of the case are on their low voltage settings.

Temperatures with the CPU set at 2.4ghz were idling around 30 degrees. I thought i'd push the CPU up to 3ghz and see what happens. Surprisingly the computer booted and seems to work normally. As I am typing this I have all 4 cores on /dev/null , loading them to 100% each - and core temperatures are 61/59/55/54. Do these temperatures sound ok for full load temperatures? Keep in mind the computer is very quiet considering the number of fans in there.

Thoughts appreciated.
 
Yes, push it HIGHER. Go for 3.2 at least. set core to 366mhz, up votalge to core to 1.4v. And see if you're stable, if not, push it up .0125 at a time or whatever your smallest step is in bios. Don't go higher than 1.5v. Then enjoy.

Make sure you disable speedstep and C1E in bios.

Also, my temps peak at 70degrees under full load for 5 hours. They get there in about 30mins. So as long as they stay < 69-70 i'd be happy.
 
Just pushing it straight up to 1.4 is quite high really - a lot of Q6600's did 3.0 at stock, so you could do 3.2 with only a tiny bit more.

Would lower the temps a bit :)
 
Yeah as MooMoo says, setting to 333mhz core will give you 3.0 and likely not require any additional voltage. But for 3.2 it wouldn't boot into windows for me so upped it slowly and found I was 30min stable in prime at 1.4v.

Your milage may vary, so just test it out :)
 
I used to torture my Q6600 at 4.0Ghz at 1.6v Vcore under air cooling - load temps around 75C....

... never got it stable mind, so ended up at 3.6Ghz at 1.45v Vcore and load temps around 65-68C across the cores.

So I think you have some mileage :D

There's no need to do this, unless it's not stable. I have both enabled on my board and have done since the day it was installed and I run at 3.6ghz with zero issues.

For me, it is well worth keeping it on for the powersaving. Less power = less volts = less heat = less noise needed to cool it when just browsing or doing other basic stuff.

drop the multiplyer and have a higher fsb with same 1:1 ram :)

Dont forget to explain the point of doing this is to overclock the ram to a greater degree than you get with a higher multi and lower fsb!!

The ram clock is tied to the fsb so thats the point in dropping the multi mate.

Thats very good. What is your cpu VID? Although not sure about your cooler. You should be having temps of around 62-65C with prime 95.

mine does 356x9 @ 1.32v, and my VID is 1.325v the highest intel ever made AFAIK. (its a G0)
does that mean my chip is far more awesome than they thought? or that I am? :p

@ OP: before i had my h50 cooler i used to run 78 deg in prime, at 3.4ghz and about 1.45v or something like that, on an artic cooling freezer7pro. not saying this is advisable, but A LOT of people have run them hotter than this without killing them. I backed off to 3.2 because the difference in voltage was too great for 200mhz, and ram dividers for my board play nicer at these speeds.

61 full load is fine for a G0 stepping, some would say low, for a B3 its also fine, but you might not want to go much further, hope you find a good speed you're happy with for the temp :D
