Well the temperatures seem to top out at 65 and the Intel spec is 71 - so I guess you have a bit of headroom, though I would strongly suggest getting a decent little cooler if you really want to push it.

If you want to do a bit of overclocking, try seeing what kind of clockspeed increase you can get to stick using stock volts and keeping the temps below 71.

Do this by increasing the FSB frequency slowly. Make sure that you change the RAM frequency (ie the divider) so that the RAM isn't running faster than stock.


That all said, bear in mind that for all the hassel you will get no better performance in games. At least the system is stable now, I suggest running it for 8 hours + on OCCT stress test to ensure it is properly stable (this is the gold standard).

i was aiming for 3GHz which i believe is possible with stock volts. thing is my knowledge on which settings need to be changed and which are safe to go up to is limited, from my little experience i have only really played with upping the fsb until it BSODs and going back down to a safer fsb.

ok will try the DVI-HDMI in a bit and then set OCCT off over night when the kids wont be around to accidently press buttons and see how it gets on

Aye, 3GHz is very likely possible on stock volts. However, I'm not sure if you want to do it on stock cooling.

Your overclocking method is generally correct. This is what I do:

Increase the FSB by a small amount (maybe 5-10MHz)
Check RAM is running at spec speed or below - adjust divider if necessary
Boot into windows
Run OCCT for 5-10 minutes

If stress test is OK, rinse and repeat process. If stress test fails, back up to previous stable setting and run that for a long stress test (6 hours +). If this fails at some point, back up overclock further and retest until rock solid.

Enjoy stable, overclocked machine.

(note, this is just for stock Volts overclocking. If overclocking normally (ie with a massive 3rd party cooler) i'd be increasing the Vcore and possibly other voltages instead of backing down the OC).

Cool stuff, give me a shout if you need any pointers setting it up.

right well i left it running last night but didnt make it to the 8hours as i stopped it to do a temp test while doing 3dmark06 (couldnt get vantage to work properly) but everything seemed ok. do these look ok for the 7.5hour and 3dmark tests?

sorry for all the pics, just want to make sure everything looks ok.

also, is it normal for there to be an 8degree difference in 2 of the cores?
 
Looks good, I would be happy leaving it like that :)

As for the core temperature difference, it is a bit big but not a massive worry. You may want to reseat the heatsink, what thermal paste did you use when installing it?

Side note: Any luck on the graphics/HDMI image? Was the "resize desktop" window off-centre?

just what was on the bottom of the heatsing, didnt apply anything else as didnt think they generally needed it.
 
Ah. As you are in a computer shop do you have any good thermal paste and thermal paste remover?

The stuff that comes with them is OK, but using after-market thermal paste should drop the temps a degree or two and may even out the core temps.

haha sorry i didnt explain very well. i work in a computer shop in a small village. the company is owned by someone that believes in buying in cheap rubbish and selling for twice the price of decent stuff.

we do have some thermal paste, unbranded though which we use on builds, thing is we dont do any high end builds due to our prices, so i dont get any experience with good stuff :(
 
Right, I understand. I suggest just sticking with how it is - its perfectly safe and the OCCT test is more stressful that anything you are likely to throw at it.

If you ever want to try some overclocking, I suggest getting a tube of Decent thermal paste (MX-3 is very good) along with a new cooler.

ok kool, will keep that in mind. if im not going to gain anything other then being able to say my Q8300 is running at 3.5GHz then will give it a miss for now.

just sort out my display issues and will be sorted :D
