MXM graphics card upgrade (heatsink)
kat:
The original design with the standard heatsink was stuck using heat-resistant 3M tape - it's used for high capacitance LED's iirc so can withstand high temperatures. The copper fins were fixed using high-temp resistance slow-set epoxy (up to 260° C) - 'QuickSteel' brand (not an endorsement obviously but what was used), but any such epoxy should work in lieu of having the necessary soldering skills!

Hi again...
Will try to find the epoxy. Should get my power supply today or tomorrow so I will have the possibility to continue experimenting.
I will know if the epoxy on my broken vga card will flame up or not ; ).
I plan to use a pentium 4 cpu heatsink as a temporary heatsink to check if everything is compatible. Will post with updates...
Cheers

Yesterday I put in the AMD vga card and the computer booted well. I put my Asus temporary heatsink on and all went well. I dowloaded and installed the AMD drivers and control panel. It worked well.
But... However... the AMD gpu only works for one screen. The other screen is run by the onboard gpu. I turned off the onboard gpu and only one screen worked on the amd card. Any idea how to remedy this?
Anyways sorry to have changed the topic here a bit. The new power supply is a charm and I now have very good motivation to find the missing copper/aluminum plate. BTW i did a benchmark test on the new card and I only gained 4fps on average for the AMD 7560 a card...
Better than nothing. ; )

According to the Elitedesk 800's manual, each port is essentially assigned a graphics processor but their output can be swapped per Windows display personalisation settings - you can't run both display port outputs from the MXM board. However, when using a MXM board boot messages are shown to whatever monitor is plugged into the upper display port (although they can be swapped in BIOS iirc).
As for the FPS, you might only get a marginal boost but you will at least being using a dedicated unit to drive the connected monitors output - the 7560 is technically comparable to the Intel's 4th gen CPU's with embedded graphics - check the list above if you want a boost.

Hey KAT... long time no chat...
No use chatting until I got all my aces anyways...
So I just got my Nvidia Quadro M2000M 4GB GDDR5 MXM 3.0 vga card and... well... the computer boots but neither the original driver works nor can I boot on the new VGA... can't even access the bios...
Did I make a mistake in ordering the VGA ... was something wrong in the specs of what I ordered?
Also... built my heat sink... had to order the 2mm copper plate from China and cut the pieces out yesterday and took them to a radiator shop nearby to have them soldered... works like a charm... ugly as hell but works and the fins are 2 mm thick so it should do the job... Frankenstein thing but looks good so far...
will upload pics soon...
Lemme know about the VGA and what you think... cost a pretty penny so would be nice to get it to work...
Cheers
