e7400 overclock

Hi everyone
I have been following this forum on and off for several years and finally decided to sign up. I have just built a new system after running an overclocked X2 3800 socket 939 for 3 years.

My new spec is as follows:

Core 2 duo E7400 (2.8ghz stock) with Freezer 7 Pro Cooler
Asus P5Q Pro
4 gb Corsair xms6400 (rated 800mhz)
Antec 300 case with 2 120mm Xilence Redwing fans in front, and stock rear and top fans running on lowest speed settings
Sapphire Radeon 4850 with modified cooling
Thermaltake TR2 RX 550w PSU
Vista 32 bit

I have overclocked so far to 3.7 ghz (370 x 10; 1.36 vcore in cpu-z) but would like to go further. Running Prime at the moment and coretemp shows temps as 72 degrees c on each core fully loaded (after approx 45 mins running). Does this sound about right, as obviously this kind of loading represents an extreme situation not replicated in day to day gaming etc.

Alos, what kind of voltage should i be looking for to get to the magic 4ghz, and would a higher FSB have more impact on performance than a higher multiplier @ 4ghz (for example, a lower multiplier and higher fsb; or higher multiplier and lower fsb)?

Cheers

A higher FSB will have better performance.

thought so....
now trying out 400 x 10 with prime, all good so far but temps hovering around 75 degrees. might have to try it with a lower voltage!

What's your CPU cooler?

freezer 7 pro

Your cpu temp seems way too high given the cpu voltage you have set, which I would say isn`t that high and the cooler you have. I would suggest you check make sure your freezer 7 pro is fitted properly and you've put the thermal compound onto you cpu correctly as well and check your case fans.

Personally, I would stop what your doing, back down your overclock and vcore, then fix your temps first before continuing with your overclocking - That way you won`t break something because of overheating.

Yea, thats quite a high temp. How much thermal compound have you put on? It only needs to be a very thin layer. Some people think more = better, but its not the case here!

its artic silver, and as i know only a tiny amount is needed i only put a small drop on the cpu and spent about 5 mins smoothing it over the surface with an old credit card to cover it all.
@ 400x 10 idle temps on core temp are about 30 on one core and 40 on the other.
