I chuckled when i saw "explain it to me like i'm five" approach Thank you both (khenglish and nando) so much for your patience and effort in this matter!!! Short story: I can report success with running 1xE mode but it was not so straight forward and nando explained and it took some guesswork as i'll explain bit later in post. There is noticeable difference in speed between 1x and 1xE mode! Here are requested benchmarks. Long story: x1E 1. Switched delay to 15 sec on PE4H 2.4 and powered on eGPU and notebook. 2. Setup 1.1x did not recognize eGPU even after extended period of time, i noticed port3 missing in system overview section of setup 1.1x 3. Manually enabled port3 in setup 1.1x and it appeared in system overview together with recognized eGPU, didn't have to do F5 4. Seting up 1xE mode on port3 5. Did Compact and "reinitialize/hot-reset ports" to get 256 MB in system overview...Compacting did not give me 256MB (at one point it even said 64MB)....reinit/reset did 256MB 6. Executed "startup.bat", i did not run this step before..ever..didn't know it was necessary, i'll look up in docs and thread what does it do. 7. Executed chainload to resume booting to windows --- windows boots displaying on iGPU and eGPU is on but has black screen --- 8. Checking windows graphic properties gives just one single video output, "Fn+F4" does not switch to eGPU 9. Checking Device manager, seeing eGPU recognized OK but iGPU with error 10. Running setup of latest official drivers for iGPU from HP site --- After setup is finished, eGPU powers on and on question to restart i click "No" so i end up with working iGPU and eGPU and device manager looks ok now 11. Run tests as requested for 1xE 12. Restart to do x1 tests x1 Steps 1 to 7 same but without step 4 of seting up 1xE --- windows boots ok displaying with eGPU as main display --- 8. Run tests as requested for 1x 9. Shutdown Next step for me is to try to automate booting to windowsto 1xE mode. I will do my homework on this on threads and Setup 1.1x help but can you guys give me some pointers? EDIT1: Found post from nando on automating startup. EDIT2: Here are results for x1E mode in 3DMark Cheers, D

is this what i should be lookign at in AIDA-64? because it says x1?! EDIT1: This is how it looks like before going to sleep, powering on eGPU and powering on laptop back on. EDIT2: If i just power on eGPU while in windows this is how AIDA-64 looks like and this is how device manager looks like.

All tests where run fullscreen (didn't see "window" option in RE5 benchmark option), not on docking bay and laptop lid closed. Getting screenshoot on dx10 results gave me blank screen in fullscreen and [PrintScrn] so i had to play with [Alt+TAB] and [PrintScrn] to get results. I will re-check whole setup including disablement of AMD sound on eGPU and redo tests but i do have questions: 1. Are variable RE5 tests suppose to be run in full screen or window mode? 2. Do i need to verify in windows is x1E mode really engaged, if so how do i do it? 3. Regarding 1/4 expected performance, is there anything in device manager you suggest i re-check except disablement of AMD sound? Cheers, D

Here are tests for RE5, as before are same for x1 and x1E. Rest of tests will follow...

Sorry, I was not clear with "ran PCISpeedTest few times but it did not show much of difference in longer tests.". I ran tests few times on both setup x1 and x1E that is why i didn't post second results, they are almost identical and there is no indication of mode in output. Only difference i could see was when i was clicking around in windows but they where quite unresponsive during tests, values dropped from 211227771.709277 to like 210xxxx..... Cheers, D

Attaching screen shoot for verification did I manage to get x1E more correct. I ran PCISpeedTest few times but it did not show much of difference in longer tests. Im not sure was i suppose to let it run whole night but last one took a while so i stopped it every time when i say numbers got stable. Here is output from one of files but as I mentioned numbers ran almost identical every time. 0 16 89968.259142 185073.791189 0 32 264436.646707 267712.923881 0 64 508931.263730 512307.656613 0 128 1173078.852779 1100926.643814 0 256 2045374.786510 2187707.159997 0 512 4138520.159608 4754876.985195 0 1024 10220309.650590 9662560.273504 0 2048 23288073.993202 26787975.878206 0 4096 42159968.375909 47693700.448241 0 8192 72036291.644763 57129406.961026 0 16384 103872245.503618 118089197.532234 0 32768 131568111.083229 159280685.367089 0 65536 154148072.070306 188248344.810719 0 131072 165666646.810459 199187185.772590 0 262144 172923254.749798 205094538.601962 0 524288 170026410.666416 208189452.025242 0 1048576 178261843.616446 209743127.171530 0 2097152 179206636.237480 210536159.496889 0 4194304 179684994.392547 210927962.755469 0 8388608 179934116.429364 211133051.296862 0 16777216 180115474.058833 211231469.309891 0 33554432 180225310.337301 211227771.709277 0 67108864 180255012.653471 211311752.398513 0 134217728 180269109.770626 211325601.466004 0 268435456 180159762.243375 211334413.467605 0 536870912 Is there a way to check which mode is currently engaged? I did see explanation for nvidia but did not see one for amd. Also one novice question, guess i could try this one by myself but since i'm writing here goes , if i want to save all adaptations with F3 in Setup 1.1x do i have to press F3 after last command just before chainloading to windows or after each executed command? Cheers, D

Hi, I got this configuration working last nigh 1. OS: - Win7 64bit, DNA-AMD GFX 12.7B.0 - x64 2. System - HP6930p, CPU P8400 2,26 GHz, PE4H ver2.4 with EC2C 3. RAM - 3GB 4. eGPU used - HD 7770 Sapphire 5. PSU specification (especially the +12V max current) - 550W, LC POWER Silent Series, ATX V2.2 DSDT method faield but Setup 1.x worked, needed 256MB free as mentioned. 3dmark results Cheers.
