 Topic: Raising CPU multiplierPosted: 25 Feb 2016 at 12:31am |

Recently decided to raise my CPU speed, but unfortunatly, when i raise CPU ratio in bios, actual frequency stays 3300 MHz. For some reason my system won't allow me to run CPU faster than x33, although in bios it says, that the set speed is 4500. I think it has something to do with MEI.
My specs: i5-2500k AsRock P67 Pro3 B3 Bios ver 3.30

Before we blame the MEI software, an important question for you:
You are using BIOS 3.30 now. Did you ever apply BIOS version 3.10 on your board? We MUST know if that was done or not before we can continue diagnosing your situation. BIOS download page for your board: http://www.asrock.com/mb/Intel/P67%20Pro3/?cat=Download&os=BIOS Edited by parsec - 25 Feb 2016 at 12:43am |

I think i first upgraded to 3.30 from 1.80 (maybe 1.90 - dont remember for sure), then downgraded to 3.10, then tried 3.20 and 3.25C and then returned to 3.30.

Sounds like you could be having the same issue I had. I have the Asrock Z170 Pro4. I would set the multiplier, Vcore and on the OC Tweaker page it reported a Target of 4200MHz, but on the Easy/Boot page it said 3500MHz. Meanwhile in windows CPU-Z kept reporting 3.5GHz. I eventually download RealTemp and it reported the actual CPU speed.

My actual CPU speed is blocked on 3300.

Ok, skipping version 3.10 before changing to a version beyond 3.10 is your main problem. The 3.10 BIOS is the (important) Sandy Bridge to Ivy Bridge compatibility update that MUST be applied even if you are still using a Sandy Bridge CPU, as you are now. It must be applied ONLY if you decide to use any BIOS version beyond 3.10, or you change to an Ivy Bridge CPU. I know this is not stated clearly on the BIOS update page, but believe me it is true. I've been dealing with this situation for a long time...  The 3.10 BIOS contains an MEI firmware update that is part of the BIOS file. If that update is not done correctly, you can get problems like you have now. You said you did install 3.10 not long ago, correct? Did you also install the MEI software update that is required once the 3.10 update is done? That would be the MEI driver on this page, assuming you are using Windows 7: http://www.asrock.com/mb/Intel/P67%20Pro3/?cat=Download&os=Win764 If you have installed this driver already and have the multiplier problem, I suggest installing the 3.10 BIOS again, and immediately installing the appropriate version of the IME driver. Or at least install this IME software, running it as Administrator on the OS drive. If you still have the multiplier problem after doing all of the above, then the only fix is getting a new BIOS chip. You can get one from ASRock, or they are also sold on eBay, for ~$20 or so. The BIOS chip is user replaceable, no soldering necessary, but must be done carefully. The BIOS chips are sold with a BIOS installed, get the 3.10 BIOS if you do this. Yes, you are not the first or only person to be in this situation, there is a small business providing this fix to users like yourself, mainly people with P67 and Z68 mother boards of all manufactures. Another thing you can try, which is not a fix but will at least verify your situation, is to install the Intel Extreme Tuning Utility software: https://downloadcenter.intel.com/download/24075/Intel-Extreme-Tuning-Utility-Intel-XTU- This is Intel's over clocking program that runs in Windows. It works fine, and uses the MEI interface to change the processor settings like the multiplier. If your MEI interface is broken, that will be apparent when you try to change the multiplier. |

I've already tried all the possible combinations of BIOS, MEI firmware and IME driver. None of them seem to work. The last option is downgrading BIOS to some older version (I think 2.0 is ok) with a programmer. Anyway, thanks for the help.
PS Haven't tried Intel XTU, but AsRock XTU doesn't work either.
