ah, would have been good to know before i threw in 4 sticks of PC3-12800 DDR3L 1600Mhz 😄 Its maxed at memory limit, just not running at max memspeed. The hyperX 1866Mhz stuff is the fastest stuff out there so i'll get that once i sort the CPU upgrade and get all the heatsinks & heatpipes for the GPU upgrade.
I've ordered the PTM7950 for the CPU work will probably go for the 40x80mm sheet so should have enough for GPU pads too if i use the 8770W heatsink.
Question for those that have trodden the path of GPU upgrade. comparing 965M to the 980M, it seems like 980 wins on paper. within reasonable budget what is the best card to fit (aliexpress seems to have many many geforce MXM boards), based on drivers working (without need to reflash Vbios etc to see the 8570W)?
