Processors On The Rocks VOL. 2

Thermic Acceleration Results

Asetek doesn't like the term 'overclocking' in combination with its products and calls it 'thermic acceleration' instead. I know that many of you will be disappointed, but I decided against posting any benchmarks with the 'thermicly accelerated' processors, as this is not the point of this article. If you want to see some benchmark scores of an Athlon running at 1400 and 1466 MHz, you should have a look at my recent article 'Pentium 4 - Final Recount '.

Let's see how far we could get the different processors with Vapochill. To produce successful results you always need to increase the processor voltage. This is not as dangerous as usual, because it is impossible to burn a CPU that is cooled down to sub-zero temperatures. We did not modify any SocketA-motherboards to achieve voltages in excess of 1.85 V, and we doubt that the results would have improved. Modifying the voltage regulator on a motherboard goes far beyond the installation efforts required for Vapochill.

We tested with the following motherboards:

• Asus CUSL2 - Intel i815
• Asus A7V133 - VIA Apollo KT133A / VIA VT82686B (pre-release)
• Gigabyte GA-7DX - AMD 761 / VIA VT82686B (pre-release)
• Iwill KA266 - ALi MaGiK1 (pre-release)
• MSI MS-6341 - AMD 761 / VIA VT82686B (pre-release)

You can see that we only used SocketA-motherboards that allow a bus clock of 133 MHz, because otherwise it gets very difficult and pointless to overclock Athlon or Duron. The KT133A boards such as the Asus A7V133 will become available very soon.

We used the following CPUs:

• AMD Duron 750
• AMD Duron 800
• AMD Duron 850 (pre-release)
• AMD Athlon 1000
• AMD Athlon 1100
• AMD Athlon 1200
• AMD Athlon 1200/133
• Intel Celeron 566
• Intel Celeron 600
• Intel Celeron 667
• Intel Celeron 700
• Intel Pentium III 850E
• Intel Pentium III 866EB
• Intel Pentium III 933EB
• Intel Pentium III 1000EB
