Thank You! Will try it. But do I understand correctly, that this is the entire modded bios so I upload it without "-me" or other flag? Just: "fpt.exe -f vii_modded.bin" ?

May I add my own bios here, that I extracted. So somebody who has already done that so many times before, can make the changes? I have the latest A17 BIOS. https://dl.dropboxusercontent.com/u/46330482/ORIGINAL.BIN What I am looking for is the CPU OC side and x2.2 capability. Also that desritor region is unlocked. Dunno, if there are other specially needed mods. I understand if I am later choosing to use faster RAM (2133mhz) instead of 1600Mhz (2x8GB) I have now. Then the faster memory should work out of the box? Just have to make sure it has CL 12, to make sure there are no boot problems.

Well I used command "fpt.exe -d origbios.bin", to dump the entire bios. Modified it, to unlock the flash deescriptor. And now I want to apply this modified bios so that I don't have to use that paperclip mod again. But couldn't I just upload the entire bios or is there a reason for "-me" flag? Without that "-me" flag and updating - will I brick the bios?

Altough I have a question about flashing modified bios back now. Do I just use: fpt.exe -f MODBIOS.bin or like this in this unlocking guide... with that "-me" part also included? fpt -me -f E6430UCME.bin

Trying this paperclip mod to unlock bios for dumping and then flashing. But I get this error. I read about that Error nr 26 means, that I don't have great connection. Or maybe I am connecting the wrong things. Should I connect pin 5 and 9 with each other (create a bridge between them)? Or what exactly, cant figure out the picture in the first post. Weird thing is that first time I tried to dump the bios with no paperclip mod, just to see if I get that error- I did. But 2'nd time I connected the pins (at least I think I did), because now it showed that "Flash devices found", which it didn't show before... but still... Error nr 26 at the end. Added a picture. What should I connect each other? The yellow connection (pin 5 to pin 9) or red connection (ping 5 to resistor)? Much appreciate the help! PS. Do I need to maintain that connection through out the entire time, or just so far when I see a boot screen and then release the paperclip? EDIT: GOT IT! Connected the pin 5 to pin 9 (yellow line) and this time it started to dump the bios. And had to hold it only when I saw the Dell logo loading. Now starting to modify the bios.

Thank You, will try that!

How do You open the program after extraction or what else is needed to operate?

This utility is needed? https://downloadcenter.intel.com/download/18317/BIOS-Firmware-Update-Configuration-Utilities-for-Windows-Linux-WinPE-UEFI OS Independent download link?

I read this thread from the beginning many times before, thats why I decided to purchase this laptop at first place. I did not make a post about my problem without reading through the thread. There was no hint in first post to enabling Optimus through EFI shell hack... or did i miss that somehow :/ ?

Altough, when I rebooted this morning at home, the POST data was on internal screen, even the Win boot logo came up on internal screen and then when login comes, it switches to external display connected to GTX670. That indicates to me that somekind of gpu was connected during post, was it iGPU or dGPU- don't know. When I get to home, I can check if there is still POST picture on screen and win logo (after disabling NVS gpu) on internal screen when booting.

Thats correct. No NVS gpu anymore listed in Display Adapters under Device Manager. GPU-Z confirms that. Only HD4000 and GTX670 is selectable from dropdown menu. Only thing left to do is to check Optimus from Bios. If it is enabled. Can check that in 5-6 hours when back at home. Can somebody direct me to the bios submenu where I can find that? And what other Bios settings should be overwatched for best performance with e-gpu?

Cant check the bios right now, because I am at work. But managed to run FireStrike test over RDP. Disabled the Express Root Port and restarted the laptop beforehand... results are even worse. http://www.3dmark.com/compare/fs/7178582/fs/7136982#

No, I didn't set UEFI variables as I connected the EC adapter booted and it worked after 2 restart (finding hardware and installed nvidia driver). In Lenovo bios, there was a place where I could set the Gen2, but in Dell bios i didn't notice that section to be honest. Have not touched TOLUD or other boot programs as Setup 1.30 etc. Where did You notice that HD4000 is secondary graphics card in my 3Dmark link? Searched myself but could not find... Another thing I noticed, that when I apply the OC in MSI afterburner. Save the settings, then after reboot the settings are defulted back to stock. Thinking about flashing my GTX670 default bios to higher clocks, but that doesn't explain lower default clock benchmark result...

This looks OK, right? It is idling @x1 1.1 but, when I open 3D program, it changes to x1 2.0. it was same with my X230 so, I guess it is normal behavior. Running HPET timers is needed only for Win8? I am running Windows 7. In Nvidia CP all settings are same- set to performance also using High Performance mode in power managment. (In my Lenovo X230 and work T440p there are more additional plans, even Maximum Performance, but that is missing in Dell. In Dell there are only 3 main profiles- Power Saver, Balanced, High Performance). Could that be the case? Because in Lenovo there are both: Maximum Performance and High Performance.

Found another comaprison firestrike core, with equal mem clocks. Altough core clock is 5mhz different. http://www.3dmark.com/compare/fs/7139888/fs/6344859# But still massive difference in graphic score If i can't get this in line and no OC, then I have to resell e6430... which would be shame. Had big plans for it.

Oh, yes the memory oc. Missed that. it actually did no difference... How do i find the correct root port to disable the dGPU? There are 5 different ports. Port1-1E10 Port2-1E12 Port3-1E14 Port4-1E16 Port6-1E1A

Yes, I still have the X230. Will test them with CUDA-z. Also will disable the dGPU. The card run pci-e 2@ x1 .2 on both laptops. About the second link score... hmm, for me it shows both have GPU clock 1110mhz. 5190 with X230 and 4924 with E6430.

I bought E6430 (i7-3740QM and with 16GB 1600mhz memory ) also with dGPU (NVS5200). Everything works fine with PE4L 2.1b adapter. No different from booting up than with my previous Lenovo X230. Basically plug n-play. All GPU's are detected and present in Win. Weird thing is that my stock FireStrike2013 test is a lot slower than with the i5-3220M in X230. Altough physics score is doubled, but graphics score is lower :S Using same e-gpu (Gigabyte GTX670 OC with Windforce 3X). That is odd... Graphics result is around -900p less all stock clocks with E6430 :/ http://www.3dmark.com/compare/fs/6344581/fs/7136982 And the most weird thing is that I cant OC my videcard anymore. Using MSI Afterburner. I apply the clocks, GPU-Z confirms that those clocks are applied, but there is no gain in graphics score like 0 effect! With X230 i had a huge bump in graphics score when I oc'd my GTX670. Comapring my X230 best OC score with E6430 best OC score. http://www.3dmark.com/compare/fs/6345009/fs/7139888 As You can see there is massive gain in Physics score thanks to 4 vs 2 core CPU, but more than -1200 point loss in graphics score. What gives? Also tried with same graphics driver versions... no change in result. It seems that clocks are applied but not utilized by program...

Thank You Tech Inferno Fan!

So no other options than to find one from aftermarket (PE4C V2.1)?

Hi. Is it possible with PE4L V2.1b (ECard version) to get 8Gbps speed with Dell E6430 doing that hack (unlocking flash descriptor) described here: Or do I need other adapter for that mod to be successful, if even then?
