Hi guys, I own a MBPr Mid 2012 with the following specs: i7 3820QM @ 2.7ghz 16gb ram 756gb ssd nVidia 650m Windows 10 technical preview My egpu setup is: PE4L 2.1B Sapphire HD7970 6GB Overclocked Vapor-X edition (2x 8pin power) 500watt psu - 18/01 swapped to 1200watt silverstone psu to fix stability problems Sonnet Echo express pro Powered 1x to 16x molex riser - 17/01 removed due to instability - 18/01 added again because stability issues were due to $20aud psu My setup if finally working! Installed bootcamp Ran bootcamp driver installation. Ran setup 1.2 (Thanks Nando!) Compacted PCI. Ran test chainloader config Booted with egpu recognised as HD7900 series in device manager. Benchmark results Unigine Heaven 4.0 extreme preset: Score of 947 windowed mode. Max fps 75 min fps 17 Cinebench r15: OpenGL score of 77 Alien Isolation: Not a real benchmark but fps didnt drop below 60 during the 1 hr of gameplay on max settings Farcry 4: On ultra settings the game is playable not dipping below 35fps with vsync on. Very high settings see an increase to a min of 45 fps. Pretty surreal what can be done with a talented programmer (Nando) and a bit of persistence. Thanks!

Hi guys, I was wondering if you could help me overvolt/undervolt the np6165/w150erq's embedded vbios. The stock sager bios dump is here, courtesy of prema from notebookreview forums: W150ER_06_stock.rar The thing i've noticed is that the 650m's max normal voltage under stock conditions is 1.037v but for some reason it goes to 1.012v when under use. It goes back to 1.037 when the gpu is not under use. I'd like to fix that for a start pls. I've also modded my laptop by adding heat pipes and stuff. More to come soon.

So... after months of wild speculating and guessing we finally have some first official numbers regarding the new mobile GPUs of Nvidia. Here the specifications listed on the official Nvidia site: GTX 660M GTX 670M GTX 675M Graphics Clock 835MHz 598MHz 620MHz CUDA Cores 384 336 384 Texture Fill Rate (billion/sec) 30.4 33.5 39.7 Memory Interface DDR3/GDDR5 DDR3/GDDR5 DDR3/GDDR5 Memory Clock 2000MHz 1500MHz 1500MHz Memory Interface Width 128-bit 192-bit 256-bit Memory Bandwidth (GB/sec) 64 72 96 Max SLI Configuration 2-Way 2-Way 2-Way 610M GT 620M GT 630M GT 635M GT 640M LE GT 640M GT 650M Graphics Clock 900MHz 625MHz 800MHz 675MHz 500MHz 625MHz 850MHz CUDA Cores 48 96 96 144 384 384 384 Texture Fill Rate (billion/sec) 7.2 10 12.8 16.2 16 20 27.2 Memory Interface DDR3 DDR3 DDR3/GDDR5 DDR3 DDR3/GDDR5 DDR3/GDDR5 DDR3/GDDR5 Memory Interface Width 64-bit 128-bit 128-bit 192-bit 128-bit 128-bit 128-bit Memory Bandwidth (GB/sec) 14.4 28.8 32 43.2 28.8 64 64 There are seven 600m series GPUs which can be considered low- to middle-end and three which are high-end.No word on the Nvidia site about which manufacturing process is being used for these chips, but the statement telling one should assume that they really shifted to 28nm only, but I want to see this confirmed before I really believe this to be true.Anyway, looking at the specs of Nvidias new mobile flagship, the GTX 675m I can't help but to think that they just shrinked the fermi architecture... the specs and clocks are identical to the 580m. They might also have messed up the numbers they put on the site, it just seems unlikely that all GPUs from the 640m up to the 675m all have the same core count (except for the 670m).Well, I guess we will see more information in the near future, when the first systems with these GPUs are getting released. I'm definitely curious about how they perform and can't wait to see some benchmarks. Also the overclocking capability is going to be a very interesting point. So far there's no word about new features for this GPU series, so it's unclear whether the "clock boost" technology which can be found in the desktop GTX 680 will also make its way to the mobile GPUs. Here some performance graphs, also taken from Nvidias website:[ATTACH=CONFIG]3707[/ATTACH] [ATTACH=CONFIG]3708[/ATTACH] So far I'm really not that impressed, though we have yet to see the real world performance, and tbh I'm really curious about the AMD 7000m series :)
