Precision M6700 supported CPUs
I have a Precision M6700 without a CPU or GPU.
I installed a Intel I7-3630qm and try to get it running. Does not seem to work. The processor works fine on a Toshiba laptop from which it came.
When I power on there is nothing in the display - he screen is blank, so is any external VGA monitor.But the power button light is on and stays on. No other beeps or lights.
I did BIST and the screen seems to be good - I get alternating RBGWB color screens without any lines etc. (As described inhttp://www.dell.com/support/article/us/en/19/sln153653/how-to-troubleshoot-a-dell-notebook-lcd-panel-issue?lang=en )
1. What are all the Intel I7 processors supported on M6700?
Prefer quad core, but I can settle for 22nm (or below) dual core/4 threads cpus also.
2. The installed CPU has integrated graphics. Why do I need an add-on GPU (MXM 3.0, I suppose) then?
I also removed and reseated the cmos battery to ensure the BIOS has the defaults assuming that doing so will default to CPU graphics capability.
Any help is greatly appreciated.
I do not do much of graphics work, need lot of cpu cycles and memory.
Thanks

That CPU will work fine on an M6700 -- less clear is whether it'll start up with a missing GPU. It WILL run if the GPU dies - on the integrated graphics -- but it may in fact not pass POST without a recognized GPU aboard. That side of things isn't clear (though your experience suggests the GPU must be there for the system to boot up -- assuming your system doesn't have a GPU.
These weren't shipped from the factory with integrated-only graphics.

Ok, thanks.
I figured out that I need a video card.
-----------------------------
Here is my current config on the M6700:
Intel cpu as above
16GB of supported memory
AMD ATI FIREPRO M5950 VIDEO CARD ( from a Dell M4600).
--------------------------
Now, the screen still passed BIST.
The screen lights up, but is completely blank.
I do not want to spend hundreds of $$ on the video card something I will not need.
How can I make this work with this video card.
Is there a way to update the BIOS (say over network) without a video card installed or update the bios to recognize this video card?
Thanks.

This is solved by myself .
Had bad incompatible memory. The memory works on a Toshiba.
Once, I replaced the memory, it was all good. No need for any graphics cards either. It used the CPU graphics features.
