GA-P31-DS3L oc to 400mhz fsb: Do I need extra chipset cooling?

post #1 of 2
Thread Starter 
Greetings,

I am currently using an intel E4600 on a Gigabyte GA-P31-DS3L Mobo but I am unable to clock this cpu beyond 3.0ghz (But this is not my issue) and I would like to get an E8400 instead and overclock it.
However, considering the E8400 multi only goes up to 9x I will have to up the fsb well beyond 333mhz.

Now I'm wondering how far can I safely up the FSB on this board without the need for extra chipset cooling? In the form of a NB fan or better heat sink. I've found that the NB heat sink on the P31-Ds3l is going to be a pain to remove (I tried before and was unable to remove the mounting pins)

A lot of reviews seem to confirm that the P31 chipset on my board overclocks fine well beyond 400mhz, they however fail to mention whether or not they achieved this with any additional cooling. I am not necessarily looking to hit the 4ghz, anything between 3.4-3.6 ghz would be fine methinks.

At 333mhz everest tells me the motherboard (I'm guessing it just means the NB chipset) is coasting along at 31c however I don't trust that sensor, it gives different readings with every bios update (currently running F9.)

Any help/insights/answers would be very much appreciated.

I had the same problem with my P35-DS3L. It turned out that the thermal compound for the NB was the culprit. A fan didn't do anything for the temps until I removed the NB heatsink and replaced the old, hardened thermal compound with some fresh TX-2. temps went down 6C and I was able to go from a 333 FSB to 400 with no trouble. Got my little E7300 up to 3.6GHz with a multi of 9. I haven't been able to get it stable at 4.0GHz, but I'm trying.....

About the plastic pins.... you have to squeeze the V-shaped part on the backside of the MB in order to get them out. Be careful, they tend to go flying when they pop out.
