NVIDIA GeForce GTX 780M video card benchmark result - Intel Core i7-3930K Processor,Notebook P570WM score: P8957 3DMarks My max with no OV vbios. 64 C for GPU

Everything is possible, if you are able to changes some components (keyboard, top case, both led board, keyboard connectors and resistors on mobo). I do not know if EC crossflash to P150/170 will not be required. I use both keyboards (in HM and SM) and older is better.

Change the thermal grease for PK-1 or ZM STG2. When tightening the heatsink push it (with finger) to the chip.

Does anyone have a P15x/17xSM service manuals?

With just unlocked vbios (without OV), this card overclock perfectly. However, with OV vbios the real fun begins.

Look here http://forum.techinferno.com/general-notebook-discussions/2221-quadro-card-gaming.html

After all GTX680M/K5KM is better card than GTX780M.

Clevorr, For better heat dissipation from the bottom of the card (lower memory chip) try to put across the width under the card a thick (100x100x5mm) thermo pad. With 1.075V vbios you can go easily up to 1250MHz for memory and 1120MHz for core.

I'm sorry I did not notice your answer before. My P150HM stock cooling system works well. It's full stable now up to 1100/2700MHz/1.05V for GPU and 2x4.4GHz for CPU. No Fn+1 The K5KM results were with untouched card. There is no Optimus/Enduro on P150/170HM.

I need a closer look at the GTX780M to go higher.

OK! Have you got the part number of the GPU and CPU heatsink for P177SM?

2x KBC/EC chip on board.

IMHO, You can not add freely capacitors because you limit voltage in the circuit (as did Clevo in HD7970M). Inductor R56 (with lower inductance than 1R0) pass higher current, which we have slightly suppress-filter with higher capacitors, but not with twice the value.

It seems to me that the problem may be weak connector or too thin cable in P150. I use X7200 300W/20V PSU and 4-pin mobo connector and it works well.

I'll try to going higher. I did not have the parts for changes all capacitors. But I already thought about dismantling 7970M for parts.

Changing the inductor (1R0 for R56) and capacitors (330uF for 470uF) work. Though with some artifacts. But it is rather the fault of poor quality components used and soldering. Above 2900MHz are too many artifacts and I fear for the card. http://www.3dmark.com/3dm11/6675176 For DC the inductor behaves as a resistor. But in this case we are doing with pulsating current. Here is a voltage regulator datasheet

Unfortunately I have no idea what it is. Oddly enough the GTX780M use the same memory chips like GTX680M (FC04 not FC03), but changed the inductor (1R0 for R56) and capacitors (330uF for 470uF). Maybe 3GHz memory operation mode it's not a matter of memory chip pin out but the appropriate filtering?

I used this method because it was easier for me to add a little resistor soldered on top of existing than replaced it. Moreover, it seems to me that other solutions did not provide a stable voltage. Never mind. My conclusion was that the 3GHz memory operation mode require a different memory chip pin out. At 1.5V the temperature rise became significant (+5 C) but for me did not cause throttling and exceeding Tjmax. The second voltage regulator (centrally located) is of course the core voltage controller.

I recommend that you read this: http://forum.techinferno.com/general-notebook-discussions/1847-nvidia-kepler-vbios-mods-overclocking-editions-modified-clocks-voltage-tweaks-104.html#post35831

DP (with dual link) works on both GPUs.

AUO B156HW01 V.4 (matte) and V.7 (glare) http://www.logicalblueone.com.au/docs/B156HW01_V_4.pdf

Excellent mod (idea with mSATA instead of HDD). If I can make a suggestion for future modders. What counts is not only the number and thickness of the heatpipes but also their length (see GPU1 and GPU2 temperature in P370EM). IMO it is better to divide the layout into two separate and connect (with short heatpipes) the new radiator to the CPU plate and the existing allocated exclusively to the GPU.

I was buying it in the Clevo service (Clevo Germany) in Germany. (Singatron 2MJ-3432-007) But desoldering is not easy and you have to cut a larger opening in the housing. But then you can use the X7200 300W PSU Good luck
