Massman Posted October 25, 2010 Posted October 25, 2010 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. PICTURES (bios V1.2) 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. VOLTAGE MODIFICATIONS OVERCLOCKING RESULTS: AIR COOLING: 1097MHZ, SINGLE STAGE COOLING: 1235MHZ [hwbot=1069611]submission[/hwbot] [hwbot=1069606]submission[/hwbot] Quote
Massman Posted October 25, 2010 Author Posted October 25, 2010 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 Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 Clarkdale coldbug modification for this board Quote
Hondacity Posted October 26, 2010 Posted October 26, 2010 i have the h57 board....i just need to look for the 750ohm resistor right? Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 Vcore and OCP modification - UNTESTED! Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 i have the h57 board....i just need to look for the 750ohm resistor right? Just look for the resistor linked to this socket pin: http://i154.photobucket.com/albums/s261/Massman-/mod.jpg Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 IGP Voltage - UNTESTED! Will test tonight. Quote
Hondacity Posted October 26, 2010 Posted October 26, 2010 Just look for the resistor linked to this socket pin: http://i154.photobucket.com/albums/s261/Massman-/mod.jpg thanks boss ..i'll post pic later on.. Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 deleted the Vaxg mod ... that was the cpu pll mod Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 Uploaded correct vIGP mod ... still untested, though! Quote
Massman Posted October 26, 2010 Author Posted October 26, 2010 IGP + Vcore voltage modification confirmed working Quote
Massman Posted October 27, 2010 Author Posted October 27, 2010 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 ... Quote
Hondacity Posted October 28, 2010 Posted October 28, 2010 whats the word with the bios? wish they have an "extreme" bios Quote
gnidaol Posted October 31, 2010 Posted October 31, 2010 (edited) Can others MSI's H55 follow the same resistor's values for the mods?? Edited October 31, 2010 by gnidaol Quote
Massman Posted October 31, 2010 Author Posted October 31, 2010 whats the word with the bios? wish they have an "extreme" bios Nothing so far . Can others MSI's H55 follow the same resistor's values for the mods?? If they use the same Vreg and the stock resistance is the same - yes. Quote
gnidaol Posted October 31, 2010 Posted October 31, 2010 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 Quote
Massman Posted October 31, 2010 Author Posted October 31, 2010 If the Vreg chip is different, you'll need to look up the datasheet of that IC. Quote
gnidaol Posted October 31, 2010 Posted October 31, 2010 (edited) 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 Edited November 1, 2010 by gnidaol Quote
e-Killer Posted November 4, 2010 Posted November 4, 2010 Anyone tested the Vcore mod?, anyone can change the Vcore on the Fly? i have killed my I3 560 by doing it . Quote
Massman Posted November 4, 2010 Author Posted November 4, 2010 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? Quote
Massman Posted November 4, 2010 Author Posted November 4, 2010 W00t! Found a new bios in my mail ... 2.081V Vaxg (IGP) Just flashed it ... works fine just stock. Hooking up the single stage tonight to see the effect . Download link: LINK Be careful! Quote
gnidaol Posted November 4, 2010 Posted November 4, 2010 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 =/ Quote
Massman Posted November 4, 2010 Author Posted November 4, 2010 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 Quote
