There was not a single point of criticism regarding the stability of the IT7 and it passed all tests without any stability problems. However, this would have surprised us, since we weren't last from any of ourtested motherboards are used to something different.
The overclocking of the IT7 is completely im Bios in place. The VCore can 'only' be adjusted between 1.1 and 1.7V in 0.025V intervals. The DIMM voltage can be used to the full and any number between 2.5 and 3.2V in 0.1V steps can be selected. With the most interesting part, namely the CPU, you can go two ways. Either you choose from a predefined range, which extends from 800MHz/100MHz-FSB up to 3200MHz/133MHz-FSB, or you choose 'User Define' and then determine the FSB, PCI and RAM clock yourself.
We can only recommend selecting 'User Define' here, because the IT7 unfortunately only operated our Pentium4 2.4/533 with an FSB of 100MHz during automatic detection and thus the DDR RAM only run at 200MHz let.
If you choose 'User Define', you can of course also try overclocking. The FSB can be freely selected between 100 and 250MHz in 1MHz intervals, the multiplier (with the appropriate CPU) from 8 - 24x and the DDR-RAM ratio to the FSB between 4: 3, 1: 1 and 'by SPD'. The possibility to fix the PCI/AGP clock in the BIOS is praiseworthy. You can choose the right one for you from five different options. You can either set the divider of the FSB to 3 or 4, or you can choose the PCI clock rate with 44, 37 or 33MHz.
The timing of the RAM can of course also be set as desired. In our test it ran smoothly to 2-2-2-5.
FSB check: Of course, the mandatory front-side bus check was also not allowed with the IT7 from Abit are missing to determine whether one or the other manufacturer would like to set itself apart from the competition with a slightly increased clock rate.
The FSB of the IT7 was 133.5MHz, which equates to a quad-pumped bus of 533, 98MHz and inConnection with our Pentium4 2.4 at a multiplier of 18 delivers a total of 2004.92MHz. So you can be completely satisfied with the timing of the FSB.
