Intel has recently released a new BIOS update for its top of the line Extreme Series Desktop Board, the DX58SO.
Here is the link:
Care should be taken when updating a Desktop Board BIOS to prevent failures.
I did the update today, and although the BCLK at setup defaults remains at 135MHz the maximum Turbo multiplier now sticks at 22x instead of going to 25x with an i7-920 processor.
I applied this BIOS update earlier today (coming from 5112). Default Turbo Multiplier is now fixed (has been broken since 4598), however it seems that Intel is finally saying BCLK is intentional in the Release Notes:
Fixed issue where setting the Host Clock to 133 (default of 135) would hang the system.
Also it appears they have resolved the issue that prevents you from lowering BCLK value below 135 if you modify memory settings (in 5112 I had to apply memory changes, reboot, then set BCLK again). Why they would intentionally have default to an "incorrect" value at default is beyond me, but at least it can be changed without too much hassle now.
Otherwise it appears about as stable as the 5112 release... haven't had any issues system not properly restarting after reboot/shutdown like the 4598-5020 releases.
Kakusso how did you recover your board after 5020?.. any help? im stuck with a bricked dx58so mobo flashed with the 5020 and watchdog disabled.. (no psot, no video, no reading form usb at all)
