Well I have the right EDP cable, but I can confirm the M17x R3 120hz screen won't work with the M17 R1 / P18e. Ripperino

Well this is exciting. I have the same P4000 gpu running in a M17 R1 (2014) that has the same 60hz LVDS / 120hz EDP options. It came with the 60hz screen but i have a dead M17x R3 with what should be a compatible 120hz panel. Hopefully it's not the C01 revision but i'll try it anyway. Just wish I didn't have to break it free from its glass prison.

Reporting back with results! I can confirm the OC P4000 vbios for Mac works great on the Alienware p18e (at least the 60hz version). No issues flashing, laptop booted right up and I didn't even need to re-install the NVCleanstall drivers. Bios revision shows as DE.EA.00.BE.EF 😅 - it now boosts to over 1600mhz and pulls over 100w to achieve a TimeSpy GPU score of 4800! https://www.3dmark.com/3dm/110489628 I don't know if the issues @0tohero04081988 had was just with the Precision or if they were trying to flash with software, but i'm very pleased with the results. No need to try the simpler TDP Tweaker bios files as it does not increase boost clocks. The macrumors modder m0bil who uploaded the files also included an experimental 'OC3' version that increases the boost and voltage a bit more. I don't feel any need to try it unless somebody here is curious. The next steps i might try is with the 120hz panel which might require a modded motherboard bios to allow toggling graphic modes.

Hey everyone, new to the forum but wasn't finding much active discussion on this so i'll leave some info here. I have two of the Alienware 17 r1 (2014) p18e models to mess around with. Both with 60hz screens however i do have a 120hz panel and the eDP cable to try at some point in the future. While optimus does tank some performance, having the intel iGPU available is nice to have as a backup. I recently bought a P4000 to put in one of them. With UEFI boot enabled and CSM disabled, it shows up just fine in windows. First as a generic '3D Video Controller' but worked perfectly after using NVCleanstall. The P4000 came with the 86.04.3A.00.3A vbios version installed. HWInfo claims it never pulls more than 70w under full load but it does achieve a 4003 TimeSpy score. That being said it never tops over 65c and I feel there's a lot more headroom. For 'science' I'm going to be flashing the Mac OC'd bios first to see if things boot and maybe achieve a 4200+ TimeSpy. Worst case i'll just increase the TDP limits using the Pascal TDP Tweaker and flash that to see if anything improves. For flashing I have the venerable CH341A with 1.8v adapter. Plenty of experience using it with desktop boards but realized I needed the 1.8v adapter for this kind of vbios chip. Confirmed first it's a newer revision and actually outputs 1.8v instead of 2-3v. Wish me luck! p.s. @jdngy if i'm not mistaken, you'll be fine with the 60hz screen. The fact it shows up in the bios but not windows means you probably aren't booting with UEFI or have CSM enabled. It also might mean it's showing up in device manager but under a weird category like mine did as a '3D Video Controller'
