Hey all!

 

I've been playing with this board for about a week now; just testing how the bios goes and playing with the Intel GMA HD overclocking capabilities. Haven't gone totally extreme yet (read: liquid nitrogen), so only -25°C single stage cooling for now.

VIDEOS:

 

I also put two videos up on Youtube. The first one is a quick walkthrough for the people who have never overclocked the Clarkdale IGP. Just explaining the basic stuff. The second one is a funny video of the IGP going crazy when the system memory is clocked too far.

 

Enjoy.

Awaiting the new bios with increase Vcore and Vigp limitations for higher clocks. Will be posting a performance scaling graph in the next couple of days as well :)

As expected, the Vaxg has an extremely strict OVP. Max I can run is 1.53V with the highest voltage set in the bios (1.448V). So, we'll need the OVP as well.

 

The easiest way would, however, be a bios that allows us to set ALL VID settings for the igp ...

Can others MSI's H55 follow the same resistor's values for the mods??

whats the word with the bios? wish they have an "extreme" bios

 

Nothing so far :(.

If they use the same Vreg and the stock resistance is the same - yes.

I'll check the resistances, but I'm sure that the Vreg is different.. but I know what is each pin, so I just need be lucky to be the same values...

It's really annoying this really low BIOS voltage limits...

Thanks anyway :)

Yes, I looked at the data sheet but it doesn't tell me resistance values(I guess that is MSI that should tell me that)... I think I'll try something like yours resistances if I measure similar original values among equivalent pins... I really hope it works...

Thank you

Anyone tested the Vcore mod?, anyone can change the Vcore on the Fly? i have killed my I3 560 by doing it :(.

Yes, I just tested it and the voltage goes up quite rapidly, so you might want to use a higher value for VR.

 

Were you monitoring the Vcore while increasing?

W00t! Found a new bios in my mail ... 2.081V Vaxg (IGP):D

 

Just flashed it ... works fine just stock. Hooking up the single stage tonight to see the effect :).

 

Download link: LINK

 

Be careful!

It's sad not to have one of those to E33 =(

 

But anyway, Let's try to mod something that looks to never been modded before... Hope not to kill the cpu like my (e)killer friend did =/

Any other boards that are going to be used for the IGP contest? If yes, please let me know what models and I'll try to push MSI for providing more extreme bioses :D
