Xevi I'd love to know how you got your boards to run anything much past 200FSB. I have one of these I bought eons ago and with it set to the 200FSB jumper setting it really loses stability around 210 ish. I've tried a load of different CPUs (eg a T5500 with a low multi), different memory modules, different voltage settings, disabled onboard devices. disabled different features on the board. Doesn't seem to matter. Usually if i try to set anything above 220 in the BIOS it'll just ignore the change and stay at 200. Firmware revision is the same as your boards.
