Hey guys, just signed up to the forum because I'm stumped. Hopefully somebody can help me out. A friend of mine just gave me an MSI PH67S-C43 (B3) motherboard with an H67 chipset, and I just can't get this thing to go any higher than 3.8ghz with a K-model i7. I know it's frequently asked, but yes, I am certain beyond the shadow of a doubt that this is a K-model. It's printed on the chip, the BIOS reads it as K-model and even shows that it's unlocked, and CPU-Z will also report that it's a K-model.
Now I think the problem is the BIOS version. It's currently running version 6.0, and per MSI's page it's only recommended if you're running an Ivy Bridge core. Obviously in this scenario I am not. I attempted to revert to the non-ivy BIOS, version 2.7, but it tells me that there is a ROM mismatch. I assume this new 6.x BIOS updates something else like the ME, so I'm kind of lost on how to revert it back. Any ideas?
Also, just to disclose my background a little, I have been overclocking since the 90's. My first successfully overclocked system was an Intel Pentium 200 MMX running at blazing 250mhz on an 83mhz bus using an Intel TX chipset. I've since had many many overclocked systems (and overclocked smartphones and tablets), so I'm no stranger to the game. My last system was an Intel Core 2 Q6600 (P35 chipset) that ran stable at 3.6ghz, so I may just be a little outdated on all of these new LGA 1155 board BIOS settings. Could there be a setting in there that's preventing me from bringing the multiplier above 38? I feel confident I should be able to run this chip ~4.5ghz with the cooling I have.
Here's a couple of BIOS screenshots. Thanks in advance for all the replies.
