Five i845E mainboards in the test: who will win?

Stability

The stability of the EP-4BEAR was convincing despite the loose Northbridge cooler. We did not have to complain about instability in our test.

Overclocking

Only the DIMM voltage has to be set with the EP-4BEAR via jumper on the board. You can choose from 2.5 to 2.9 volts in 0.1V steps. The VCore can be increased in the bios by a maximum of 0.35V to 1.85V and decreased by 0.1V to 1.4V. In between, each value is available at a distance of 0.025V. The FSB can be set in 1MHz steps from 90 to 200MHz and the RAM, as already mentioned, can be operated with either the “Auto”, “DDR266” or “DDR354” option. When fixing the PCI/AGP clock, there are three options to choose from: Auto, FSB/4 and 33/66MHz. So, at least here, nothing stands in the way of successful overclocking. With the DDR-RAM-Timings you can also lend a hand with Epox. As with the IT7, timings of 2-2-2-5 did not cause any problems here either.

FSB check: With the front-side bus, Epox is a little less precise gives an FSB of 134.00MHz. This results in a QDR bus of 535.98MHz and with our Pentium4 2.4/533 a total of 2411.92MHz. Epox does not yet advance into the regions that we sometimes already know from Asus, but it should be clear that it could be more precise if you wanted to.
