Hello, I have been testing this mobo how high fsb can it handle and I managed to run it on 510*6. Then I tried mutliplier 7 and it worked with fsb500 and MCH manualy raised to 1.2 Then I tried multiplier 8 and I was not able to get it over POST even with FSB 440 and vcore 1.408. When it was trying to boot and restarting itself, suddendly there was a message that BIOS checksum is bad (or something like that) and it restored BIOS from the backup chip, so I was back at version F3 (from F6). That was yesterday.
Today I tried again booting with FSB 500 and I could not do that no matter what settings I used! This settings was set by BIOS (auto settings) yesterday when FSB500 worked: CPU termination:1.6, PLL:1.85, MCH core:1.4 and ICH core:1.2 so I have set it manually today but not even FSB440 posted.
Flashing BIOS back to F6 did not help. Now it boots only with FSB less then 440, so I run it with 430*9 and it works! Interesting thing is that I can set it to 460*8 in windows via Easy Tune6 and it seems to be stable even with prime testing, but it cannot boot with these settings...vcore was all the time around 1.4
So the summary would be:
yesterday:
510*6 - boots
500*7 (MCH set to 1.2V) boots (maybe something happened to the board here:o)
500*8 does not post. I lowered the fsb gradually all the way to
430*8 and it finally boots
425*9 (3825MHz) boots and seems stable (today...)
460*8 (3680MHz) set with ET6 and seems stable, but overheats (water cooling planned...).
I have Fortron blue storm II 500 PSU.
Suggestions?
