I'd just go eBay for a 970m, I just sold mine last week....I upgraded to 980m. The 10-15% improvement was too much to resist, and it was only $50 more than what I sold my 970m for .

 

Either way, 970m is a great card for the M15x and OC's like crazy too. The 980m I had to make a dual psu (240w x 2), as any attempt to OC would trip my single psu. 

Awesome mod Mr. Fox!

 

I know this thread is dated now, but for others who are curious, a very easy and straight forward mod. Most importantly, relatively CHEAP.

 

I have a M15x (owned new since 2010) and after having a 970m for a year, I upgraded to a 980m, the 10-15% gain was enough of an itch for me. The only problem was the 980m would trip my 240 psu constantly with any attempt to OC (svl7/johnksss vbios). So I purchased another 240 psu and made the mod - now no more tripping!

 

For those with a AW M15x, a dual 240w psu mod is plenty and even easier to construct than the 330w mod, as the 240 psu's have only 1 black, 1 white, 1 green/blue wire..I didn't even have to solder anything!

 

Now my laptop has more than enough power 

Look on Ebay for similar specd latops and see what their selling for. Guessing $600-$700, obviously the gpu has most of the value. List with a "best-offer" option, and decide what your willing to let it go for.

I've read 2 sticks of 8G Crucial Ballisiix Sport 1600MT/s PC3-12800 CL9 is the best for this aging legend!

 

 

I might try older Thermatake Tide Cooler looks like very simple install.

CMOS Battery?

Anyone have success with a 980M?
