Asrock P67 Extreme4 UEFI & Drivers thread [Extreme6 & Pro3 owners welcome]

[mean6]

I have 1 HDD and no CD/DVD. 1 classic Compaq PS/2 keyboard and MX518 USB mice. 'll try to disconnect the mouse and I have 1 wireless dongle, will disconnect it too and see. Isn't the HECI error about wrong version of MEI on the uefi rom? The error is with 1.XX and 2.XX versions, which otherwise are working flawlessly (exept the mentioned in my case already). The error is not present on 3.XX, but I have mandatory hangs on it, and there are wrong XMP profiles -which doesn't bother me, but there are wrong value readings as well (IMHO). Furthermore, I think Asrock can't be unaware of that, they definately know for the HECI error, after rollbacks to earlier uefis. Probably they don't know how to fix it yet, or don't want to. That's why they don't responded on my problem. And the hangs in 3.XX are (I think) random Incompatibilities with some mobos, pending to be cleared (hopefully) in the next versions.

New developments:

First on the advice of unplugging anything to check if the issue with hanging with 3.XX will disapear. There is only the mouse and a wi-fi dongle. I unplugged them and.. same hangs. So, I abandon the 3.XX until those problems are figured out.
The interesting is the development in the problem with the two errors "error! system cannot get fw version!" and "heci pointer mismatch" ater the rollback from 3 to earlier. In the meantime of the fore-mentioned experiments I was with V.2.1, and decided to manualy downgrade the Intel management engine interface driver in windows, just to see what will happen. I was with 7.1.40.1161, which I downgraded from 8.0 earlier. Deleted the old one and Windows installed automatically ver. 7.0.0.1114. Then I flashed uefi to v.2.1H - I already tryed that version, but now just decided to stay with it for now. Restarted, the system turned off, turned on, posted, shuted down again, posted again and after the post screen updated the ME on the rom chip, restarted again and... no more errors with 2.XX uefi. I can't repeat the exact procedure, but obviously it is possible to rollback between 1.xx, 2.xx and 3.xx without errors. After loading windows I noticed, the ME driver version is updated to 7.0.0.1118. Now I have completely normal post and OS loading without any errors. Just a small glich - the mouse directions in uefi are turned upside-down, but don't care. Now Im clocking back.

Hey FTA7700, I was having the exact same problems as you after flashing to 3.04 or whatever it was. My previous posts are above. I had those issues, in addition, I was not able to overclock with a multi higher than 37, and the ram options were only 1066/1333. I also had the errors you had after trying to downgrade (which you are told not to). I tried everything, and nothing would get my system to recognize more than 8 gig of ram, or allow for high overclocks. I resolved my issue by purchasing a new bios chip with 2.0 preflashed onto it. It cost me about $16 on ebay. It just arrived, and took 2 seconds to install, and now everything is good. Overclocked, and ram is running as it should be. Hope this helps.

So, obviously the 3.XX are problematic in some cases. Although, my problems was with hangs (something like timeouts) with constant duration. Of course, as I mentioned I saw strange readings and fluctuations in frequencies and voltages and wrong XMP. The multiplier selector was fine by my opinion. But, in the memory settings for frequency one could see numbers like 1336mhz, 1674mhz and such nonsence. The thing with the new bios chip is good idea. But as I wrote, my problem is solved I have no error messages anymore. The real problem is Asrock are silent as a fish about that, and official way of rolling back to earlier uefis. Thanks for posting.
