Phase change cooling is a known cooling way in our day .Vapochill , prometeia , OCZ Cryo-Z and custom build are very popular , all those phase change cooling allow to reach the maximum clock frequency from cpus, video chips and motherboards .

In this case most people suggest to use the Arctic ceramique as a thermal past since this last , hold low temp ( up to -200 c ) while other silver paste are intended for + temps . Today we have tested 3 thermal paste using vapochill ls . Here is the list of thermal paste used :

1) The well Known Arctic ceramique

2) One of the best thermal paste Arctic Silver 5

3) Arctic Cooling MX-2 also very popular thermal paste

The result was really impressing , according to Arctic , the MX2 is able to handle up to -40 C  and this proved to be true . Here is how we tested . Mounted the vapochill ls (modded ) using each thermal compound and tested using prime (Small FTT) for 8 hours . Then we waited another 8 hours and tested again (1 hours test) . CPU  and evaporator temperature was checked with our digital thermometer .The CPU used was a E8500 @ 5 GHz with 1.65 v (about 200w heat load)

Here is the observed result for the first run (1 hour):

Here is the observed result for the second run (8 hour later , one hour test):

In a word the MX-2 is a leader for subzero and positive temp , Give it a try u will never get back :-) .

The commercial deliveries of 45 nm processor deneb will begin in the fourth quarter, we already reported about the engineering model witch overclock to 3.44 GHz frequency . Passage to the new technical process will bring an improvement in the energy consumption indices,  65 nm processors AMD with four core at 2.6 GHz frequency  have a TDP level , equal to 140 W. More economical processors will appear within the 65 nm technology, but the existing elder models phenom X4 are capable of experiencing problems with some motherboards .

Associate report that the engineering model 45 nm processor deneb, which works at 2.3 GHz frequency with 1.22 v, has a lower energy consumption in comparison with its 65 nm analog. Here is the engineering model 45 nm deneb processor  : it is released on 16th week 2008,  in the middle of April.

Let us recall that the cache volume in the third level for 45 nm processors deneb is increased to 6 MB. Without load this processor consumes 7 W less than its 65 nm analog . Under load this value increases to 24 W. If we speak only about the 45 nm processor, then under load it consumes 29 W more than the idle conditions.  The temperature of 45 nm processor does not exceed 31 degree Celsiuses, against 40 degree Celsiuses in 65 nm processor.

GIGABYTE UNITED company declared about the release of eP45-Extreme motherboards, oriented to the amateurs of extreme overclock. Currently this series include the model GA -EP45T-EXTREme, which supports DDR3 memory , and the model GA -EP45-EXTREme, DDR2 memory . Both models are made on base of intel p45 express.

Motherboards series EP45-EXTREME support multi-core intel processors with system bus frequency up to 1600 MHz , including the prepared on 45- nm technologies. Furthermore, those motherboards support ATI crossFireX technology , they are supplied with two interfaces PCI express 2.0 ( x 8)  and two local network interfaces .

The cooling system GIGABYTE hybrid silent-Pipe is noiseless and effectively reduce the temperature of the north , south bridges and power transistors . Moreover the cooling system GIGABYTE hybrid silent-Pipe can be also used with water cooling systems.

eP45-Extreme were supplied with light-emitting diode indicator Post codes and with signal light-emitting diode indicators of the overclocking conditions , increasing the supply voltage and temperature. When the processor and north bridge temperature are located in the range 61°C - 80°C, we have a green light-emitting diode, but when the temperature exceeds 80°C, we have a red light-emitting diode. GIGABYTE series eP45-Extreme adapt an integrated circuits for voltage regulating , which allow a wide control capabilities of supply voltage for the northern bridge and memory.  

Furthermore, those hardware regulators ensure considerably a more sensitive voltage control , making possible experienced users to regulate the supply voltage with a step of only 20 mv (0,002 c) and to increase therefore the overclock effectiveness and the accuracy of control system parameters  . EP45 extreme is equipped with 12- phase power-supply system for the processor, and by the 2- phase modules for the north bridge and memory, which allow a stable supply to all computer components in any condition .

Yesterday associate reported with the reference to information obtained from Microsoft, that DirectX 11 will be supported only by the operating system Windows vista and by its successors.

New API will ensure not only more realistic graphic in games, but also will help to use video chips for the nonstandard objectives. Obviously, following NVIDIA, AMD and Intel the urgency of video chip resources use for accelerating calculations and work will be realized by Microsoft company . 

It is important to note that DirectX 11 will support the multi threaded use of resources, and this allow to increase the productivity of computers on base of multi core processors. In the near future Microsoft will report additional details about this interface.
