Thread: Over clock Pentium Extreme Edition 955

After using normally the new Pentium Extreme Edition 955 from Intel, we decided to give it a try over clocking divided into several parts. In this first part we did a test using a classic liquid-cooling system of Ybris Cooling using an icebox, water, a dozen thermal containers and 300 ice cubes. We will explain later how we have assembled this cooling system and how it works.

The processor we used is an Intel Pentium 955 Extreme Edition. This processor, with 65 nm manufacturing process, is a dual-core Presler core with default and works at a frequency of 3:46 GHz We decided to use this processor because the heat sink series, raising the multiplier to 13X at 16x we reached 4267 MHz, corresponding to 4.26 GHz

As already mentioned in the previous page we used a kit cooling Ybris Cooling. The system / kit Ybris used consists of pump Aquarius III Nj 1200, Water block Ybris One, three meters of pipe Crystal 10 x14 mm and a bracket for socket LGA 775. Here is a photo of the water block Ybris One.

With the kit described above using water without any special cooling except the radiator, the water temperature was around 15-17 ° C without support the water block on the processor. Now we will see the changes we made to our test.

In the icy water that was in the icebox of ethanol and then we added more ice to prevent water from freezing at low temperatures. The thermometer probe was fixed between the neoprene and cold plate as you can see from the picture below:
