Both boards are not significantly different and the BIOS may be used interchangeably. Clevo P157EM | NotebookReview

Kepler-BIOS-Tweaker

Simply, using a multimeter and logic. Seriously, I made a resistors mirror image of my both K5000M and GTX680M pcbs. Yes But I not proved anything yet because the card still works just like the GTX680M. Quadro drivers normally recognize both systems and start installation but only the Ge Force drivers are installed, and in SPECviewperf11 card has performance of GTX too. Unnecessarily I changed also one of the resistors because GPUZ shows that the card has Hynix GDDR5. In fact it has GDDR5 from Samsung. Edit: Resistor marked in white on the back of de card (on the right of the picture above) is a GDDR5 manufacturer ID resistor where 45K is Samsung and 35 is Hynix assigned.

Recently I got hold of GTX680M, which I was able to convert in K5000M. In front: 1. You need to unsolder the 5K (R42) resistor marked in red. 2. You need to solder the 25K (R40) resistor and 0K jumper (R49) in places marked in green. In back: 1. You need to unsolder two 100K resistors marked in red (on the left) and 35K (on the right). 2. You need to solder 35K resistor in places marked in green. Resistor marked in white (on the right) is a GDDR5 manufacturer ID resistor where 45K is Samsung and 35K is Hynix assigned. 3DMark11 stock + 135/1000MHz Only BIOS has some problem yet with the proper card recognition. Have fun.

Dell vbios and modified inf should work.

Open HWinfo64>Summary>Video Adapter>NVIDIA Quadro K5100M and check your subsystem ID: Hardware ID: PCI\VEN_10DE&DEV_11BC&SUBSYS_02711558&REV_A1

What drivers you use?

Is subsystem ID of your laptop specified in the driver inf file? %NVIDIA_DEV.11B8.0271.1558% = Section109, PCI\VEN_10DE&DEV_11B8&SUBSYS_02711558 Green-GPU device ID , Red-subsystem ID 0271-P570WM3 subsystem ID 11B8-K5100M device ID

First time, I was not able to calmly verify the intermediate stage, namely K5000M vbios and 5K ohm resistor. It was not me soldered, I leave such details skilled in the art. I'm already soldering back EEPROM with K5000M vbios but the POST or something is stuck. Tried everything and I can not repeat this scenario. I do not understand why. I saw 1,536 cores in GPUZ after driver auto-installation. GPUZ shows 1536 cores also with K5100M vbios before the drivers installing so there is no certainty that it does not do auto-refilling error? When it comes to performance of K5100M 1344 cores was only possible execution of Specviewperf11. What is normal for K5000M 1344 cores stock. Unigine Heaven barely walked. 3DMark11 barely walked and finally crashing. K5100M 1344 cores is back K5000M QS. Resistor table could by OK (if R >= 39.5K). From the beginning I knew that such a swap may not work well (redesigned PCB, 4 vs 8 GB of GDDR5, the lack of a second resistor ID). After early experiments with exchange of the GPU chip from desktop to mobile, I was almost certain that nVidia uses the same chips for almost all Kepler's GPU. One, what I've learned from Clevo, that it is not the hardware but just the license matters. Therefore, I wanted to confirm that the change of the number of cores running depend on resistors ID and vbios, not of the chip itself. Unfortunately, the experiment did not fully succeed because I am not convinced that GPUZ after soldering 5K resistor really seen 1536 cores whether, only reading K5100M device ID from resistor (11B8 instead of 11BC), automatically complement the data, but at least my K5000M QS was for a while a K5100M and it is still great.

I finally found a 5K resistor (can be 2X10K in parallel). 1. After soldering 5K Ohm resistor instead 25K Ohm on my K5000M QS with K5000M vbios, Windows automatically installs graphics drivers and GPU has 1,536 cores. However, the card is visible everywhere as the standard VGA. 2. After soldering vbios chip with Clevo K5100M vbios, the drivers are installed only after INF mod. The K5000M QS is now K5100M with 1344 cores. Without drivers With drivers

Are you tried Clevo vbios from here? http://forum.techinferno.com/clevo/7348-nvidia-quadro-k5100m-clevo-vbios.html#post104993 Do you have any pictures of your K5100M?

I find something. I cant find first byte resistor of device ID but I think that I find second. This resistor had 30K ohm (11BD) in my broken Quadro which corresponds to K4000M, 25K ohm (11BC) in K5000M QS and 45K ohm in GTX780M where it should have 40K (119F)??? I have not 5K resistor for try to change K5000M device ID for K5100M (11B8).

I'm not sure. I think it's K4000M board. BTW R49 in K5KM is a jumper 0 ohm.

R49 can be just a U505 surroundings or ID resistor like you said. I compared the values of resistors between broken K5KM and my K5KM QS. Except the number of active cores there were no differences between both cards which confirms bios, nv inspector and GPUZ. Conclusion, the card has a damaged or different power section traces on PCB. Anyway, in K5000M resistors id have no relevance to the number of active cores. Unfortunately I do not have GTX680M at home to compare.

I think that, co-creating new concepts based on the revolutionary low-cost technologies like graphene, Clevo can leave copper era and co-create future of electronics, or join to other ODM chasing own tail trying to beat the competition for better barebone for $ 100 piece. I presented the simplest possible concept-layout HCCH (Hot-Cold-Cold-Hot) for LGA + MXM 3B SLI that is HCCHCCH. Such a combination would be more efficient than previously used CHHC-layout. You can criticize everything, but first, please suggest a better cooling solution. Size does not matter. Important to attempt.

It's not so easy. Firstly, PCB of K5000M differs from GTX680M presence of the U505 and its surroundings. Secondly, I compared the resistors with my K5000M QS. I found nothing. I'm old and tired so I could have missed something, but in my opinion, that PCB is responsible for the number of active cores. At least in K5000M case.

A little too late. As I have more time I will try to put together and test. From what I remember this K5000M/K4000M with a GK104 chip from the GTX680 (desktop) had still a K4000M performance (6-7000 points in 3dmark11), same like with early 1149 A1 chip with which it got.

K5100M from Dell works well in Clevo just with moded inf. Only K5100M from HP were the problems of bios-vbios incompatibility.

I know this is not the bios only but its on connection with the power section. And what if that board id, or some stupid power phases jumper, decides the number of cores running? Perhaps my damaged K5000M is not damaged but only is K4000M board crossflashed on K5000M?

I did not notice this thread earlier. In brief. After my experience with the GK104 chip exchange in damaged K5000M for a GTX680 desktop chip (1203 A2), it seems to me that the number of total GPU active cores does not depend on the same chip, which in GK104 is almost identical for the desktop and for the mobile GPUs. It seems to me that it's only bios-power section depends.

The grey area is battery (below GPUs). Blue zones, it the PCIe/Power interfaces. Customizable Power/ I / O boards. Separate from motherboard and more or less complex depending model's size.

Really? On the other side of the mobo, you can put 2x RAM + 4x m.2 slots (in 13.3" body).

Perhaps because of some total (CPU+GPU) TDP limit?

Don't mixed up notion of feasible from a cost-effective. BTW, the scientists, considering mass and surfaces of wings they calculated, that the bumblebee could not fly. Nobody told the bumblebee about it and it's still fly.

In the P570WM was enough to redesign the motherboard. Namely, cut holes in the motherboard for the MXM GPU. It would be a thinner laptop or more efficient cooling. IMO, LGA2011 + MXM 3B SLI in 13.3" x 1" thick, this is the challenge but it's fully feasible.
