Falkentyne Posted February 15, 2013 Share Posted February 15, 2013 Hi, I currently have a 1761 whitebook with a 570m (overclocked to I think 790/1600, although I forgot the exact RAM value). I heard you can drop in a 675M (basically a 580m) into the whitebook without any problems (besides needing an extra thermal pad). I have two questions, though. Do you need a BIOS update for the 1761 in order to support the 675m? Or does the stock bios already support it? Do you need a BIOS update for the 680m? If so, how would I go about this, before I spend a LOT of money and have it potentially wasted? Is there anything specific i need to know about if I do NOT have to update the BIos on the whitebook or if I do have to? There's a "MSI MS-1761 Unlocked.zip" file in the other thread but I can't download it to even see the readme because I'm new here... does this unlocked BIos allow direct support for a 680M? (I'm a working person so this is really a hassle... I feel sort of uncomfortable thinking of five "useful" thinigs to post, when all I want to do is avoid wasting hundreds of dollars on something that may not work...and I have a fever, too.... I'd appreciate any help in this matter. Thank you. 1 Quote Link to comment Share on other sites More sharing options...
canada2005 Posted February 17, 2013 Share Posted February 17, 2013 My MSI GT780 which is the 1761 had the 560m. I bought a 580m and it throttled. Some said that if you use throttlestop they could get past the throttling but I could not even with the upgraded 180w (vs stock 150w) powerbrick. The whitebooks are not much different if I remember. I have now gone to a Dell 7970m with a heatsink from the MSI GX60(hard to find unfortunately at the moment) Quote Link to comment Share on other sites More sharing options...

Pay attention to correct contact between new heatsink and not only GPU chip / MEM but voltage regulator mosfets with high temp conductive thermal pads to avoid throttling then...
