MSI B75A G43 overclocking/BIOS issues
« on: 09-January-13, 11:13:44 »

Hi guys, this is my first post on MSI forums so don't judge me too hard if i'm posting in wrong section. So, before Christmas i ordered MSI Z77A G41 but shop mistakenly have sent me an MSI B75A G43. Indeed they're offering me to exchange it but that would take 2-3 weeks, so decided to stick with what i've got. So here's my issues so far:

1. I can't get any higher CPU overclock than 3.6GHz. When i set multiplier to x37 or x38 the actual CPU speed is 3.6GHz at best (sometimes it drops to 3.4GHz), though Windows  system is reporting 3.7 or 3.8GHz respectively.





I have disabled Intel Turbo Boost, EIST and C-States in BIOS. I have tried every BIOS version available for this motherboard but no luck. Am i doing something wrong or this motherboard just misbehaving? Other than that it feels stable and very fast.


2. Second issue is VCORE voltage. Overclocking CPU automatically raises VCORE voltage despite the settings i use (i have set +0.00V). Is this normal? If so, could we have negative values please, as with 1.1V other people having stable 4.2GHz+.


If you need more information feel free to ask.

Current setup:
i5 3570K
B75A G43
8GB Corsair Vengeance DDR3 RAM
GTX 670
850W PSU

B75A can't be overclocked, take the exchange.. see if they will upgrade to a z77a-gd65 for the troubles  ;-))

Ohh, but... Then why max multiplier is x38 if it sticks to x36 despite my setting? I'd be happy for now with 3.8GHz. Thanks for quick reply btw.

It isn't designed for overclocking simple as that. You can try to increase the turbo multiplier settings and might have more luck there, but if you want to do any real overclocking you will need the z77-xx
