Nvidia GPU Upgrade Help

I'm looking for someone on the forum who's very savvy about Nvidia mobile GPUs. A mostly successful MXM upgrade still requires some tweaking. If anyone is really knowledgeable, could they please PM me?

Related to this question, I've been trying to find someone who belongs to the Guru3D forum. Both I, and the technician who did the upgrade, have been trying to join that forum because of its heavy emphasis on Nvidia, but the website never responds to registration attempts, or emails to the administrator. Perhaps a member of that forum could intercede.

Thanks.

 

GPU MXM upgrades only work depending the laptop makers some allow and some don't allow. So check with them to be sure and then report back. Otherwise you will have to list the laptop specs in details so others can compare to similar or if they have the same model and tell you what you can and can't do in GPU upgrades. Just remember the ones that allow GPU upgrades are Gaming Laptop not your everyday of the mill laptop those will if the do requires complete board swap and those prices would be cost prohibited to do. And some laptops don't give you GPU upgrade options and your stuck with what they give you.

 

The upgrade is to the HDX Pavilion 9000 Dragon series laptop…a 20 inch laptop that originally came with an Nvidoa 880M GTS. It has been successfully upgraded to an Nvidia Quadro 3700M. However, the Dragon's screen is a dual lamp backlit. Presently the 3700M which comes configured in a few dual lamp display laptops apparently is only activating one of the two lamps in the Dragon's display, so that we only achieve half brightness. Whenever the reason, everything works except we are at half maximum brightness.

Thanks for your interest.

 

An update on the GPU issue. My tech friend has determined that both backlights are producing normal brightness, but somehow the screen remains somewhat dimmer than normal.

He almost describes it as being something to do with contrast, or possibly gamma, but the result is that the screen underperforms compared to the 8800M driving the screen. It's his feeling that this has something to do with the VBIOS. Curiously, loading the 8800M GTS VBIOS onto the Quadro 3700M brings the screen up to full brightness. It just doesn't enab;e other features of the 3700M

That's where we are now. Any help would be appreciated.

Thanks

 

I'm still hoping that someone with GPU and Nvidia knowledge will see this thread.

So my technician friend discovered something interesting using the related Nvidia Quadro 2700M in an HP 8730.

When the 8730 is on battery the screen only gets so bright. Even with the brightness turned all the way up it still looks significantly dimmer than on AC. Is it possible that there is a pin or sensor or something present on the 8730w that tells the 3700M MXM card it is on AC rather than battery? If this is true, is it possible that the HDX Dragon has no such pin or sensor, and that is why the 3700M remains somewhat dim?
