No, i just choose this one because it was the cheaper one with external clock gen. I mod the latest bios 3801 with ME 1191 and it boot with Celeron i'll try the Xeon.

It's working on BIOS version 3801 ME 1191! Need to check if bclk is working. But i don't think it will, this BIOS version has C2 mCode revision. Edit: No bclk for now, System turn on but no video.

@dsanke Do you know what ME version it was on those mobos?

@dsanke Well i test the BIOS version 0050 that you mod, but didn't work, ME version was 11.0.0.1168. I test BIOS 1702,1801 ME 11.0.0.1168 none work. I got it working with BIOS 3801 ME 11.0.0.1191 but no BCLK OC. Do you think C2 mCode revision block the BCLK OC? Or is it the BIOS vesion?

Cool you got it working now Now all you need is to use the mcode version mentioned above and it should bclk overclock for you!

Is there a guide on how to change the mcode? Can i use MMtool to delete one and insert the other?

I manage to delete the C2 and insert 74 mCode, but i can't pass 102.5mhz. Could be BIOS version?

Is mcode 74 the one in use once in windows? Verify with AIDA64 or HWinfo. And yes, could always be BIOS version blocking too, try all same mods onto an older BIOS, early ones that next ones say you can't flash back after update

Yes, HWinfo show mcode 74. I'll try some old BIOS. Thank You @Lost_N_BIOS and @dsanke for you support.

Good, that means you changed it properly and windows has not over-ridden it yet. For the Bclk, yes try older BIOS or older ME, hopefully you'll find one.
If you see BIOS version skipped in older updates, like only 3, 4, 5, 7, 8, 9 is there, but not 1,2 or 6, then try to find on web 1, 2 and 6 and try those.

So, i tried almost all BIOS from ASUS web site. This versions (0230, 1203, 1302, 1402, 1602, 1702, 1801, 1902, 2202) all originally came with ME 11.0.0.1168 none work with the mod. This versions (3007, 3301, 3801) originally came with ME 11.6.10.1196 but i downgrade to 11.0.0.1168 and they all work, but no BLCK OC. There something on old BIOS that don't allow ME to be disable, i think.

I think ME disabled is going to disable your ability to overclock via Bclk since this is controlled via ME initially, correct? Why specifically do you have to disable ME vs use certain version ME like all the other posts in the main update thread? Due to Xeon only, I yes why?
Maybe time to sell the Xeon and purchase with those funds a CPU that will cause you less stress and hassles. Or maybe not Bclk overclock? Seems like a waste to chase this anyway for few MHz

Here, i think bclk is possible but only with external clock gen as i say on others posts. There are some BIOS that allow bclk oc but they didn't work with ME disable. But there is something weird, i flash a specific BIOS version for blck oc with no mod for disable ME and that didn't work too. I already put this board for sale, probably gonna put the Xeon too, thing is a got it for real cheap. I thought that it would work with bclk oc and make really good price/performance.

Wish it would work for you since it was a good deal. Maybe they changed something in the BIOS blocking that. So you test other non Xeon CPU and regular BIOS, that doesn't need any mod for CPU, with blck overclock BIOS and it didn't work either? If yes, then sounds like they block something in the BIOS stopping it
