ABIT BX6 2.0 Motherboard

Overclocking
ABIT has always intended its mainboards for overclockers. About a month ago we were pretty sure that ABIT BX6 Rev 2.0 remained an indisputable leader in terms of overclocking, but the present situation makes us doubt the correctness of our verdict.

"... jumperless technology is much more convenient and less tiring when overclocking."


What caused this sudden uncertainty? Actually, nothing extraordinary. The thing is that ASUS managed to make a mainboard with incredible overclocking abilities. Nobody expected anything like that, especially when it turned out that this sensational mainboard is a slightly revised P2B! (By the way, AOpen and MSI also offer similar mainboards – AX6BC and MS-6163 correspondingly - but we won’t dwell on them here as they are very much like ABIT BX6 Rev 2.0) Compared to ABIT BX6 Rev 2.0, the new ASUS P2B Rev 1.10 also supports a wide range of frequencies: 66, 75, 83, 100, 103, 105, 110, 112, 115, 120, 124, 133, 140 and 150MHz. However, ASUS applied a different clock generator that is why the FSB values on ASUS P2B Rev 1.10 and on ABIT BX6 Rev 2.0 do not coincide. So, a very interesting question comes up: which is better?

We carried out a number of overclocking tests for Intel Pentium II 450. Normally, it can be overclocked up to 504MHz (4.5x112) on both motherboards. Here are the achieved results:



If you look through the following table it will be obvious that if the BX6 2 hadn't been able to up the VCORE, the ASUS P2B Rev 1.10 could have been the winner. But since the processor core voltage control on ABIT BX6 Rev 2.0 is a reality, it allows to get better overclocking results. Moreover, after having finished with ASUS I was absolutely worn out: I had to reconfigure jumper set with my own hands! So, I arrived at the conclusion that jumperless technology is much more convenient and less tiring when overclocking.

However, it is not all. We have to mention another very important detail. If you compare the FSB sets of ABIT BX6 Rev 2.0 and ASUS P2B Rev 1.10 then you will notice that ABIT’s values concentrate mainly around 124-133MHz, and the ones of ASUS around 110-112MHz. So, it means that ABIT BX6 Rev 2.0 allows overclocked CPU fine tuning in the domain where FSB frequency is over 112MHz, while ASUS P2B Rev 1.10 will allow the same thing somewhere near 100MHz. All these facts prove that 66MHz CPU (particularly, Celeron) overclocking will go much better on ASUS P2B Rev 1.10 because it permits to increase FSB frequency very slowly and smoothly in 100MHz domain. ABIT BX6 Rev 2.0 offers only standard 100, 103 and 112MHz.

But in case you overclock a 100MHz CPU above 112MHz, then ABIT B6X Rev 2.0 is exactly what you need because it offers perfectly fine CPU tuning for all values surpassing 112MHz.

Summing up everything mentioned above we have the following conclusion. ABIT suits perfectly for Pentium II overclocking, and ASUS – for Celeron. And the possibility of manual voltage control – the main argument of ABIT’s most ardent fans – loses its seeming significance, when we say that a simple piece of scotch-tape can help you change CPU voltage on any mainboard. Besides, you can carry out some mechanical reconstruction of ASUS P2B Rev 1.10 which will also allow you to take voltage control.

In conclusion, we’d like to mention once again that all the offered FSB frequencies exceeding 133MHz are nothing but a clever marketing trick. You can hardly find any memory working at such high frequencies, and mostl AGP videocards will not perform in such tough conditions.
