tbalazs14 Posted December 4, 2014 Share Posted December 4, 2014 System14" HP Elitebook 8440P, i5-520M 2.4Ghz, 4GB RAM, Intel HD iGPUWindows 8.1eGPU partsPE4C V2.1 expresscard eGPU kitGainward GTX 560 video card/Gigabyte GTX 660 Ti OCFSP350-60MDN - capable of 19,5A on the single 12V railDetailsHi to everyone in this forum!I just built my egpu system with the new PE4C V2.1 and i want to share my experiences. I have a HP Elitebook 8440. When i first started the system with the egpu attached (single x1 with the express card), i got a black screen, as lapytopy did. But after setting the SW2 switch to 2 (CLKREQ delay to 11.97 sec) i got a fine bootup. So no setup 1.x was required. I am using an FSP-350-60MDN ATX PSU, if that is important. Operating system is Windows 8.1 x64.

I do not know how much power PE4C requires, but I think it's time to replace my power supply. Quote Link to comment Share on other sites More sharing options...

racsodg Posted October 25, 2016 Share Posted October 25, 2016 hello could help me please. I have the code 12 on my HP 8440w ELITEBOOK and have the same components that you appointments. I do not understand is how you do this ... "after setting the SW2 switch to 2 (delay CLKREQ to 11.97 sec) I got a good start." .. I could help please Quote Link to comment Share on other sites More sharing options...
tbalazs14 Posted November 7, 2016 Author Share Posted November 7, 2016 Sorry, I don't really know anything about the 8440W (though I think it must have an Nvidia graphics chip onboard), because I had a 8440p. Since then I sold my it, and both the GTX 560 and the 660Ti GPUs as well. The SW2 switch on my adapter has 3 positions. What I did then to make it work, I set the SW2 in the middle position, then plugged the express card in the 8440p, then started it. On the picture, both switches are in the 1st position.

Splitframe Posted November 29, 2016 Share Posted November 29, 2016 Great post with all the pictures. Do you plan to build any form of case for it and use a smaller PSU? Quote Link to comment Share on other sites More sharing options...

tbalazs14 Posted December 13, 2016 Author Share Posted December 13, 2016 Sorry, I do not know the exp gdc, and how it's switches work. Try all switch positions. You can try putting the 8440p to sleep, then insert the express card, and then power it up again, if cold start does not work for you. I also got black screen at start and that is why I had to delay the CLKREQ# signal. Quote Link to comment Share on other sites More sharing options...

anternal Posted September 11, 2017 Share Posted September 11, 2017 The x1 @ 1.1 bandwith makes using internal screen absolutely imposible. Only external screen can show some acceptable framerates in many games. 8x60 or higher is recommended for EGPU setups. Quote Link to comment Share on other sites More sharing options...
