Thank you I had a feeling it was that simple but was confused when I saw an old benchmark of a card someone posted that was like "1 x2.0 VS 1.2Opt" and it made me think they were different things

I'm confused, so does having the iGPU, dGPU, and eGPU all enabled at the same time have any advantage if the eGPU performance suffers?

How would I know if I'm utilizing the 1.2Opt compression? I feel like everything that comes up on the subject is 2 years old..

I couldn't find anything on this and I'm really new to this so forgive me if this is common knowledge I got an eGPU setup within the week and have been messing with it on my Sager NP5165 / Clevo W150HRM laptop, I also got eGPU Setup 1.30 I noticed that the setting enable x2 mode didnt work for my laptop or any Series 6 chipset in general because this was controlled by something called the "Flash Descriptor" Didn't even know this existed So I did some research and everything that came up said it couldn't be done or not without doing some form of "hard core hacking of the bios" whatever that means but regardless I couldn't find anything on how to enable this feature I downloaded FPTw64.exe and dumped my bios I opened the bios in FITC.exe version 7.1.20.1119 because from my understanding other versions will give an error upon opening the bios I navigated to PCH Strap 9 and modified the PCIe setting to allow x2 I built the bios but an error was spit out and the file was no good... Opening the file in UEFITool.exe showed that some offsets were changed, attempting to flash the resulting file didnt work So I dumped my Descriptor region with FPTw64.exe "FPTw64.exe -d Dec.bin -Desc" and compared it with my built bios using HxD hex editor The first time I did this there were 17 discrepancies, so I went through each and every one to see what they did Ultimately I narrowed it down to one hexadecimal that controlled the PCIe x2 settings I saved the hex change, opened the file in FITC.exe and sure enough the setting was set to PCIe x2 I used FPTw64.exe to flash the Descriptor region using "FPTw64.exe -f [FILENAME].bin -Desc" The flash was successful except my keyboard stopped working so I had to hard reset Rebooting into eGPU Setup 1.30 showed the change worked Although my understanding is this settings does nothing for me since my laptop is only equipped with a single PCIe x1 port Also my computer has USB 3.0 set to port 2 and ethernet set to port 4 so flashing the modified descriptor region disabled those on my laptop Reverting my Descriptor region required me to use MESET.exe to unlock my flash descriptor to flash back, which is weird because I didn't have to use it the first time I hope this helps someone with a Series 6 chipset who can actually utilize it

hex editing the flash descriptor worked for me but it didnt seem to be 100% effective I am currently running my default flash descriptor with pcie x1 PCI Compaction->32BitA->disablesunused->ignoredGPU->iGPU/eGPU->disabledGPU->P3 Gen2 x1 1.2->chainboot->test (<--- I think I'm doing this right?) My eGPU will idle at x1 1.1 and bounce to and from x1 2.0 Underload by clicking the ? in GPU-Z my eGPU stays at x1 1.1 I am unable to launch MSI Kombuster, "Unable to initialize the 3D window. An OpenGL 4.0 support is required." I am unable to launch 3D Mark Firestorm because it crashes Ice Storm works but barely...

Laptop Sager NP-5165 / Clevo W150HRM - BIOS: 1.09 Unlocked - EC:02SA Fan Control i7-2860QM 2.5GHz Corsair Vengeance 16GB DDR3 1600 Crucial M4 240GB SSD Nvidia Geforce GT 555M 2GB - vBIOS Overvolt Hi, So I'm trying to setup an eGPU and am not 100% sure what I'm doing, I'm really new to this so any information would be greatly appreciated I have a PE4C v3.0 that I got here on amazon, The card I have is an ATI 7870, and a brand new 500W ATX PSU that I found under my desk lol I uninstalled my dGPU drivers, disabled the dGPU in device manager, powered down, removed my WiFi card, installed the PE4C to the mPCI-e port, hooked up a 500W ATX PSU, plugged in the 7870, fired it up The card was recognized so I installed the drivers and ran a benchmark, the scores were suuuper low, worse that my dGPU, GPU-Z showed the card was only running at x1 1.1 speeds I looked into setting the mPCI-e port to Gen2 and eGPU Setup 1.30 came up, so I bought it and tried to figure that out..PCI Compaction->32bitA->ignoredGPU->iGPU/eGPU, disabled dGPU, set Gen2 1.2 on my eGPU which shows as P3, robooted The card still ran as x1 1.1 with the same horrible bottle necking even though eGPU Setup 1.30 said it was x1 1.2 I looked into setting it to x2 and read that Series 6 chipsets are unable to do this because of the "flash descriptor" and when I tried to enable this in eGPU Setup 1.30 it said this as well So downloaded FPTW64 and dumped my Descriptor, Opened it up in FITC.exe ME 7.1.20.1119, modified the PCIe function to be x2 for P1 and P3 which disabled my USB 3.0 on P2 and ethernet on P4, I was unable to build this flash descriptor because the build spit out errors for some reason, I opened the generated flash descriptor with UEFITool.exe to see that the region length was different as well as the offset was different and the me region was different..it also said everything was read write yes for some reason..so I opened the original flash descriptor and the generated flash descriptor in HxD hex editor in compare mode, there was 17 differences so I went through each difference to see what they did, I narrowed it down to one hex change that controlled the PCIe x1 x2 function so I modified the original flash descriptor with the hex edit and flashed it to my system using fptw64.exe -f desc.ben -desc it worked, aside from no longer having usb 3.0 or Ethernet my eGPU Setup 1.30 reflected 2.1 for P1 and P3 as well as 2.2 if I enabled gen2, but after booting to the OS my GPU-Z still shows the eGPU running at x1 1.1...the eGPU will occasionally idle at x1 2.0 but under load it will switch back to x1 1.1... After all that the benchmark only went up a little... I had a little panic when I was unable to flash back my original flash descriptor because of was write protected but I came across MESET.exe and was able to restore my flash descriptor re-enabling USB 3.0 and Ethernet Can anyone help me with this? I'm so lost Am I SOL because I'm running a series 6 chipset? Am I supposed to be doing something else? Thank you

Hi I have a few questions about this adapter I am interested in picking one up for my laptop Sager NP-5165 aka Clevo W150HRQ i7-2630QM 2.0 (soon to be i7-2860QM 2.5) 16GB 1333 DDR3 (soon to be 1600) Nvidia GT 555m 2GB/Intel HD 3000 Although my laptop does have a gpu it is quite dated, would I yield significant performance increases from an egpu even though it is bottlenecked at the mpcie? my laptop does not have a EC slot, only one mpcie, will that be fine or is that less than ideal? which adapter should I be considering? the EXP GDC V7 or the PE4C V3.0? From what I've briefly gathered the GTX 680 seems to be the go to card for this kinda adapter. is this the case or is there another card I should consider? Which card would yield the best performance? ati or nvidia? I briefly read that nvidia allows for use of the laptop monitor where as ati doesnt, is this still true? I briefly read that ati cards can use something called "gen2" while nvidia cannot, does this mean ati is a better card for this? or am i mistaken any information would be greatly appreciated, as soon as i feel like i have a solid grasp on this i would gladly order the parts :]

Any chance of modding the bios to a throw back Clevo? W150HRM/NP5165 Links to old mods are dead, someone had a gpu voltage increase mod but dead link as well I could upload the bios files and would be greatly appreciative
