Upgrading MXM graphics card in a 600-1390 touchsmart

[OmenGamer79]

I have an HP Touch Smart that is no longer under warranty.

The mother board has a dedicated graphics slot for MXM-A 3.0 slot.

Right now I have a Nvidia Quadro K1100m with a flash v-bios compatible with HP Notebooks and Dell Notebooks.

The Nvidia Quadro K1100m doesn't have enough computation power to run newer more graphically intense games (due to driver limitations) and due to the locked v- bios feature of these graphic cards to work specifically for HP I am un able to update the driver at Nvidia's website.

For example: Doom Eternal states I need the newer quadro  k1100 driver update at Nvidias website, but the driver is incompatible with the bios of this graphics card.

I see that there is an ebay vendor selling a Nvidia 1050 TI, claims that it has a flash bios for HP and Dell Notebooks. Vendor is asking for $280 after shipping costs, from china.

Looking for any help from HP support that can release the library list of graphics cards compatible with the Notebooks, and AIO's, so it can save me a headache shipping back graphics cards until one with the correct bios works.

Any help is much appreciated.

Thanks!

Hello
sorry a very big doubt for this type of modification
If we search, hp indicates HP Retired Products Policy

https://support.hp.com/us-en/retired-products
It is that more than ten years, more manual, documentations, nothing
but given the age of the pc, i think it would not accept such a recent card, you usually need a uefi bios, which is not the case (unless the model is special?)

OK so if I de-solder the  v-bios chip from my k1100m graphics card, and de-solder the unlocked v-bios from a 1050TI. swap the v-bios chip from the k1100m onto the a 1050 TI then what would the effect of that be?

Wouldn't the the system just assume its a k1100m when infact its a 1050 ti.

I've seen in many forums and on power up there are "fake" v-bios swaps to get the systems to work on the UEFI firmware.

Frankly I am not a technician, this type of manipulation seems hazardous to me

If it works so much the better I would say
but you risk spending a small amount of money, for nothing if everything is screwed up afterwards

And you might like both definitely

After a week of research and going through HP's UEFI bios .

I found that the HP touch smart 600, touch smart 610, and the Zbook  share similar UEFI bios (with minor changes from G1 to G3). This offers a wide range of interchangeability between graphics cards even from newer generation graphics cards, that normally couldn't be used on the touchsmart 600 series. 

I was able to update the Nvidia K1100 graphics driver using the Nvidia K1100m  driver for Zbook. Driver works with no issues at all. Downloaded from this section Driver- Graphics.

https://support.hp.com/us-en/drivers/selfservice/hp-zbook-15-mobile-workstation/5387800

It appears that HP did have a V-bios specific MXM-A  Nvidia Quadro M2000M (4GB V RAM), and a Nvidia GT 1050 (4GB V RAM). I will be doing more homework to cross reference the bios systems for inter compatibility, to determine if these cards as well will be interchangeable for the touchsmart 600.

As of now I have upgraded the power supply to the zbook 200 watt power supply from the touch smart 150 watt power supply and everything appears to be operating smoothly with no significant over heating. With the Graphics card now fully powered my system with the K1100m measures at 165 watts, so I have room to add the GT 1050.

Doing more homework and will see where this goes.

Thanks for helping.

Hello
it won't change anything I don't think.
But I don't understand your comparison, how do you find that uefi bios are shared?
Your computer, for him I can not find much but it would be an old computer with windows 7, Intel Core i7-740QM processor! Normally non-UEFI bios
The link you give for the newer Zbook is a 4th Generation Intel Core i7-4900MQ laptop
Possibility Windows 8, so uefi possible
In any case, not at all the same model of motherboard
From what is to use a relatively close driver, that seems quite normal to me, but I do not see it to do with much newer graphics card models, for this model therefore ..
I could be wrong, and if you can get it to work, but it's just that here I don't understand the link about uefi motherboard bios

This isn't a standard HP touchsmart. Through the years I've been modding it.

It doesn't have a 740qm, it has a 920xm. (You can go to user bench mark and see my system is the only system with the 920xm)

This Touchsmart has windows 10 installed.

This Touchsmart originally came with a nvidia GT 260m (38 watts), upgraded to the nvidia K1100m (45 watts).

K1100M was never sold for the Touchsmart 600-1390, was actually available after the touchsmart 600 was discontinued. (My system is also the only system in user benchmark using a K1100m.)

HP uses a authentic signature for its UEFI bios which really hasn't changed so that specific cards with specific v-bios is recognized by Mother board bios.

Any HP mxm specific graphic cards have interchangeability with UEFI and windows 10 that pairs the hardware .

This is where I got your reason
Unless you have changed the motherboard, for one with uefi bios, this model should not have uefi bios, but an old bios, that's what I don't understand!
I'm curious about computers, so if I can learn something new, I take

You haven't changed the graphics card yet?
I ask because you marked your answer in solution!

[OmenGamer79]

I haven't changed the board its a pegatron board that comes with the 600-1390.

The graphics card that is updated thus far with most current driver support is the K1100m, which shouldn't be compatible with this model. I had a 2016 driver for the k1100m that was having issues, and Nvidias website wouldnt allow me to update the driver stating there was incompatibility. Then went to the driver support for the Zbook and it worked and updated to the most current driver. (You can see the results in user benchmark comparing all models of the 600-1390, mine being the only model with the 920xm, with k1100m graphics card)

I just purchased  a quadro m2000m 4GB that were used for HP zbook and dell precisions, to see if it will then accept that graphics card.

So far I have tested and can confirm the GT 260m, GT630m, Quadro K1100m are confirmed to work with this pegatron board.
