Gotcha, the 3.0 standard does communicate directly with CPU, also according to spec sheet. The one I linked, (I believe) is the chipset in our motherboards. I forget the exact source to that info but that's what I dug up a week or so ago. Regardless, it was one of three possible chipset candidates and they were all virtually indistinguishable anyway (in PCI terms I was checking). I agree that all the lanes seem enabled and that makes sense because Lenovo likes to add options to build to suit (TV tuner card, anyone? haha) and the more options the merrier.
If it's not clear, in the pic with the blue X, that's just a bay. The bay itself is not exciting, a blank space of plastic. However to the left of that bay you'll notice a punch of copper leads.. here's a better pic.

You can see the scale, next to that half-mini wifi and those TINY antenna leads lol. So it would be seriously tricky solder work done with a needle tip and temperature controlled iron, but all that's missing is this.. to then have an additional mPCIe gen 2 speed 2.0x (yes I was getting those mixed up but for my purposes they were interchangeable anyway
) IF that area of the moBo is accessible to the system. I mean, it seems we have the BIOS access to ensure it's not disabled there, but the manufacturer could have omitted an smd resistor somewhere down the line and that's the major impasse. Anyway, I must respectfully disagree; it is relevant and perhaps significant as well. EDIT: is it bad/a potential security risk to have the serials and barcodes to my hardware up there? Lol
But what is the point, there will be no real gain. And yes it is bad to post S/N on net.

Not to argue, but you seem to be just the person I want to talk to about this
MMM I read 8
Not that I can guarantee I'm interpreting it properly..[ATTACH=CONFIG]13857[/ATTACH]
Meanwhile, I am also booting from 256GB mSATA (Plextor).. and it's excellent. But, I gather mSATA is recognized as IDE or SATA by our machines.. they pins look the same as mPCIE but are different standards. From wikipedia: "The connector is similar in appearance to a PCI Express Mini Card interface,[43] but is not electrically compatible; "
Therefore, I don't believe there's a PCI real estate issue! And, there's clearly a port on the MoBo which simply lacks the mPCIe header. I'm just wanting to use this extra, still mystery!!, and presumably x2.0 port as a means to not lose wiFi, or lan, or what have you.. to get an eGPU to work
I need/prefer laptop and desktop modes.I somewhat doubt that the GTX660M is using more than PCI 2.0 speed connection but that's purely conjecture! It just seems like, great gains are made with eGPU at x2.0 speed so why would that be possible if the local GPU was in x4 or x8 mode.
Anyway thanks for the great info I'm now interested in re-pasting and upping voltage for GPU. Also, very cool about 3920XM!! I was always wondering if that type of mod was possible. Best luck on your quest to unlock its full potential!! I'm gonna try to keep an eye out for the progress on that, friggin cool mod
I am 1000000% positive the 660M is 3.0 x16. Hence why it is (somewhat) necessary to disable it so that you can reserve the PCIe bandwidth for the eGPU. The eGPU must be PCIe gen 2 link because both the mPCIe port, and the PExx passive PCI adapter only support upto gen 2.0. As to whether the eGPU itself supports 3.0 speeds is irrelevant.
Secondly, I think you are mixing up PCIe link speeds and PCIe bandwidth.. There are only PCIe link speeds of gen 1, gen 2, and gen 3. Possible bandwidths are x1, x2, x4, x8, and x16 (powers of 2). PE4L can only use x2 because the actual physical connection does not fit, leaving part of the GPU pins unconnected; AFAIK, the PE4C can do x8. PCI real estate is not a concern whatsoever when you're adding an eGPU. The limitations of the external GPU is limited to the following: the GPU itself, the specific adapter you're connecting with (PE4L, PE4C, etc etc), PSU (power going to GPU), CPU (potential bottleneck), and active PCI ports along with BIOS settings. I read somewhere that using an odd numbered port (WLAN), and having its adjacent even numbered ports disabled can significantly increase bandwidth.
The reference sheet that you're referring to is specific to the chipset and limited to the motherboard. Basically when Lenovo or its manufacturer designs the motherboard, they can choose not to add all of the lanes, which in this case I'm sure they used all of them. I'm not totally sure about the existance of a "mystery port" but I am 100% positive that it completely irrelevant and insignificant in adding an eGPU to the Y580. Hope that helps

I'm asking cause that MSR is disabled for any non-unlocked SB CPU and can't be enabled in this case. Sorry.
I just recently upgraded my 3610QM to a 3920XM, but no matter what I try I can't increase its (unlocked) multipliers. I have a y580, using eGPU w/ GTX 970 & disabled 660M using a 120W charger (default is 90W). Do you think I can do something similar to what's in the OP w/o bricking? I have tried XTU, reflashing main stock BIOS, (your) main modded BIOS, Intel ME FW, and throttlestop without success. XTU provides nearly the same functionality as my locked 3610QM, only difference being the sliders for the multipliers but I can only decrease and not increase. Any help, tips, or thoughts are greatly appreciated

Oh dear lord.. I guess no one knows how to google anything anymore.
I'd like to know the answer to this as well.Ordered an Intel Ultimate-N 6300 AGN card so I can finally use the 5GHz band on my router.. just need to do the BIOS mod to remove whitelisting!
Yes you can boot to mSATA (why wouldn't you be able to?). I have an SX300 256 mSATA SSD I've been using as a main drive. You can change the boot order of your drives in BIOS (even without flashing modded version) and just have your main drive be at the top.
What's up!I have some trouble with update BIOS.
I try update, make DOS flash, but my laptop don't want load flash drive. I try on/off uefi, usb legacy, and other critical BIOS options. Just black screen couple seconds, and after jump to next position on boot list.
Maybe i mus change some setting in UEFI menu?
Boot your laptop and hit F12 on the same screen you would hit f2 to enter bios. Select your flash drive.... And revert any settings you did to get this to work.
is it possible to increase voltage for gpu in this bios?Yes it is possible, however because of the vbios being integrated with the main bios, you won't be able to change it on the fly. Send me your BIOS and I will modify the GPU voltage for you. The highest you can go is 1.2125 V, this is a hardware & driver limit by nvidia. Be warned, your idle GPU temp is going to increase significantly so make sure you repaste and use a cooler.
Can someone please help me with this item?In my work I used GPU intensively (CUDA-code). Therefore new default 1GHz clock can lead to GPU overheating...
How I can switch this item in mod BIOS to Lenovo default?
Unless your laptop came with faulty parts or you're using your laptop where the ambient temp is very hot, 1 GHz clock is not going to cause overheating. IIRC stock clocks is 800 something so ~200 extra MHz is only going to increase the GPU temperature only under load. At the very most you will probably only notice 3-5 C degree difference.

I count six thereSATA is IDE also.. It's listed that way in BIOS and IDE has other incarnations like DVD so I assume its different. Even if it isn't, there's space. I'm waiting til 14nm GPU's (or at least 20) before trying it but adding a port for this application is well worth it to me.. any insight on whether or not it's actually possible much appreciated. I know I could use the WiFi port I just added from this very helpful thread, but I'd rather not, as it turns out
- - - Updated - - -
Out of curiosity, did you swap CPU's? Like, change out the actual chip? That's cool...
I don't know if you're understanding me but just to clarify, there is no mystery port. If you check the datasheet for your CPU, you'll find the max PCI configurations are 6. Specifically, 1x16, or 2x8, or 1x8 and 2x4. Source: http://ark.intel.com/products/64887/Intel-Core-i7-3920XM-Processor-Extreme-Edition-8M-Cache-up-to-3_80-GHz
That link is for the 3820XM, but I think this is the same for all 7-series chipsets. When you say it is well worth it to you, if that is supposed to mean that you'll gain a significant increase in bandwidth/performance, you're mistaken. PE4H will use x8 lanes, regardless of how you configure it. You cannot increase bandwidth using something that isn't there to use.
&& Yes, I took out the 3610QM and replaced it with 3920XM just to prove to all those people saying the y580 can't handle a 55w cpu lol (: Just can't figure out how to increase its multipliers..
-
Does anyone know how to OC 3920XM or any other unlocked CPU on a Y580? I just bought this 3920xm thinking I'd be able to increase its unlocked multipliers but unable to in both the BIOS and Intel XTU (as well as throttlestop). I assumed the ICC registers lock in BIOS would be lifted once an unlocked CPU was detected. If you have the 3720qm or are able to help me, please reply or send me a PM. Thanks.

Well dunno if you've gotten these but here are a few of Video/GPU menu..
My question is, in the following pic, is there potential for soldering on an additional mPCIe port to run a PE4H diy eGPU dock? I'm fairly handy but it's more an issue of whether the port is available to the system. I notice the whitelist BIOS tells me a lot more about available ports, and was wondering if someone could determine if it's functional?
[ATTACH=CONFIG]13795[/ATTACH]
In the much improved BIOS, there ARE some good clues that it could work.. as there are 8 lanes PCIE.. presumably, 8x 2.0 configuration for PCIe for the HM76-express chipset..
[ATTACH=CONFIG]13796[/ATTACH]
All of these lanes are set to "enabled".. is there any way to determine which lane would relate to the "mystery" port?
Thanks much!!
I have personally done an eGPU setup with a GTX 970, except I used PE4L, not PE4H (I plan on upgrading to this next). With that being said, there is no need for any soldering to be done. I'm pretty sure the only difference between PE4H and PE4L is the actual interface the GPU will be connected to, where everyone else remains the same e.g. the other end of the flat, mini-HDMI cable, which is a mPCIe connector. The ports you're able to use (that I know for sure and have personally tried) are the WIFI and "LAN" ports. The LAN port is right next to the WIFI one, in your picture where you have the teal-colored X. Obviously the ideal port to use is the one for WIFI because you don't have to tape the mPCIe cable since they only come in half-length sizes and secondly the WIFI port is an odd-numbered port (which is what you want).
In regards to your comment on the "8 available PCI lanes" you have to realize that some of those are already being used by 660m, GbE port(Ethernet), WLAN port, LAN port, and I think the mSATA and SATA are the other two. BTW, when you first setup your eGPU, you will want to make sure wireless lan is enabled under configuration if you decide to use the WLAN port; for the LAN port you will want to go under advanced -> peripheral -> enable lan and disable the option underneath that pops up after enabling. Regardless of which port you use, you have to set PCIE reset and ASPM to disabled, and PEG0, 1, 2, 3 to Gen 2 under advanced->video.

First off, all of these questions you're desperately wanting the answer to have already been answered and could be located using a simple "search thread" query.
Hi Guys, one question, can i flash 5DCN90WW bios if my stock version is 5DCN40WW, just installed win8.1 do i need to do this??Hi there. I've been thinking about flashing your BIOS, but I have one doubt. Is the BIOS version kinda related to a OS ? Do I need a special BIOS version depending what OS version laptop i got ? I see there are two basic versions: 2.0x and 8.0x I don't want to brick my laptop so I need to be sure. I've got 2.07 BIOS (from Lenovo website) and originally my Y580 was without an OS. Now I am on Windows 8.1, So what BIOS version should i flash ? 'Lenovo Y580 / Y480 BIOS v2.07 (5DCN40WW) -> unlocked, whitelist removed, Nvidia 660m @ 1GHz default 3d clocks,' this one ?The 2.XX BIOS version is the default/stock for those who purchased the y580 which had Windows 7 already installed. The 8.XX BIOS is for the Y580s which came with Windows 8/8.1 installed. If you had a laptop that had Windows 7 as the stock OS and then installed Windows 8/8.1, you may or may not receive an annoying watermark and dysfunctional secure boot functionality which is a part of Windows 8/8.1. Since we're talking about any Y580 that had Windows 7 OS as stock, it will be running 2.XX BIOS version which was not made for Windows 8/8.1.The solution to this is to ofcourse flash the 8.XX BIOS version.
But be warned
Make sure you do exactly what <insert someone with a success story's name> did in order to get the results you want. There have been a lot of people who have successfully flashed an 8.XX BIOS on top of a 2.XX version. Search the thread for the how, I'm just telling you all the why.
@bORZZ, you don't necessarily need this, but it allows you to change the short and long power limit duration & TDP, able to disable hyperthreading/cores/etc/etc and if you're planning on an eGPU setup, it is absolutely necessary to unlock the bios, 2.xx or 8.xx doesn't matter.
i CANNOT CREATE THE BACKUP FILE. I CLICK ON THE BACKUP.BAT AND IT JUST OPENS AND THEN CLOSES ANY SUGGESTIONS AND NO .BIN FILE IS CREATED. NOT SURE WHAT TO DO I REALLY NEED THISHit start, type cmd, right click -> run as admin -> cd <path of backup.bat> -> backup.bat -> enter

I have problem with my Y580, I was accidentaly installed G580 bios for Y580. Now flashed with right original Y580 bios 5DCN90WW (V8.01), but EC version still remains for G580 5ECN96WW. Due to this fact some functions doesn't work: keyboard backlight and some functional buttons. Already tried to flash with modded bios version from first page, but EC version still remains. I think, that EC change is not included in BIOS file. Could you help me how can I get back EC version to factory?
I have attached original Y580 BIOS file 5DCN90WW (V8.01) - it's factory backup from laptop with right EC version.
Try restoring it via BIOS recovery. Search this thread for "bios recovery" and select my username in adv search, I posted a tut some pages back.

I have a Lenovo Y580 with 5DCN90WW (V8.01) BIOS and I want to remove the WL.
I want to make a copy using fdpw64 but I got an error:
"Error 104: The 2 SPI Flash devices do not have compatible command set."
The 'Error 104' - fix I have another error:
"Error 103: There are no supported SPI flash devices installed."
I remember seeing this mentioned in earlier posts. Search the thread, you should find the solution.

I have posted it before, but it seems that svl7 never comes here again.(busy maybe)
Could someone get svl7 informed?
Or someone with an SPI programmer and some BIOS modding experience*

How to setup an eGPU with Y580:
- Buy/get a PE4L-PM060A adaptor, GPU, and an appropirate PSU which is able to provide steady 12V/16A (or you can use two PSUs if your PSU can provide it but not at a steady rate.).
- Although not necessary, go ahead and download svl7's unlocked BIOS here. When I was troubleshooting my setup to get it working, I reverted to stock BIOS thinking the problem lied there, but eventually upon random startups, it would be buggy, and sometimes take a while AFTER rebooting for the display to switch from the internal LCD to an external monitor. Unlocking it lets you change an option that the stock does not allow, it also lets you tweak some other settings which may improve CPU performance.
- Go into the BIOS, and under configuration, change SWITCHABLE GRAPHICS to UMA GRAPHICS.
- If you've unlocked it, go to Advanced settings, then to Video settings, select PCI Graphics (or PCI express, ... I'm writing this from memory), then change primary display to Auto-selected. For some better CPU performance, go to the power tab, CPU settings, then disable C-States, disable MSR Lock, and set the last two settings to the maximum. You can do this by hitting f6/f5 (can't remember which) after highlighting the option. Hit F10 to save and exit. If you don't have Throttlestop 6.0 already, download it, start it, and go to TPL settings (which are now unlocked thanks to disabled MSR Lock), and change 26 to 56 for the time setting, then set the long and short TDP to however you see fit. I personally use 56 for long and 60 for short. Apply, OK. Uninstall your NVIDIA drivers (I recommend DDU) and Lenovo Power Management.
- Power down everything (duh) and plug the PE4L in the WiFi slot or the empty modem slot (WiFi slot is easier since you can screw it). Flip your laptop over so it is upright, making sure it's on a flat surface. Plug in your GPU and any necessary 6-pin cables from your PSU along with your SWEX. And last but not least the floppy molex, peripheral cable to 4 pin cable onto the PE4L adaptor itself. If you don't have SWEX, you can just grab a paperclip, cut it into a U shape, put one end on the green wire hole space thing on the 20/24 ping PSU power cable and the other end in any black one (there is a black wire right next to the green). Place electric tape over the exposed part of the paperclip to secure it.
- If by chance your PSU *should* be capable, but you are having issues (like me), you can use two PSUs by having the second PSU power the PE4L adapter using the floppy molex. Use a second SWEX if you have one, or do the paper clip method.

I'll post pics later.
6111 seems to be my max, since I can't push the clocks further than 1084/3225 core/mem, but it's probably that I don't have a "proper" PSU and/or know the right voltage.
Here's a vantage score, I only ran it once since I don't use it very often.

Great. Is that 3dmark11 score with the internal LCD? The 5213 GPU result similar to 5493 what I got on a i5-3320M + [email protected] (internal) http://forum.techinferno.com/diy-e-gpu-projects/2747-%5Bguide%5D-12-dell-e6230-gtx660@[email protected] .
If it's all working, would you mind doing a Y580 guide eGPU writeup along with full external LCD benchmarks (3dmark06, vantage, 11)? We don't have a Y480/Y580 guide as yet. Noting the modded bios capabilities would be helpful there as it might eliminate any need for Setup 1.30 software for PCIe port control as well as extract maximum CPU performance as you note.
Sure thing, and I never use the internal LCD, except for when I want to toy with BIOS, so this is all on my external tv via HDMI. I just flashed my modded BIOS, will post a score.

I tried -100/-100 on the core/memory clock with no success and gave up. If I'm going to underclock this card significantly it defeats the purpsoe of my upgrading to the 750Ti. I'm just going to use my desktop with the new card. Really appreciate your help. Thanks.
Try to do what I did. Use nvidia inspector to force the pstate which allows for custom clocks. It's different for every card, and just because we don't/didn't have the same issue doesn't mean this will/won't solve it. Worth a shot. I used this as a reference. nVIDIA mobile Kepler 6xx MASTER overclocking guide. Workaround for max clocks/OC stability.
-
Does underclocking the card get you stability? There's been problems of NVidiaGPUz being overclocked beyond what they are capable of. Lowering the clocks will also draw less power. Use MSI Afterburner or equivalent tools from Asus/EVGA to underclock.
I've been underclocking it before trying to put some load on it since the start. Only problem with that is I can't figure out what combinations of memory, core clocks, and voltage offsets to use. Too low and it will crash followed by an auto reboot. Also, I can't seem to get any undervoltage settings to stick. I'm using nvidia inspector.
928/2153 for core and memory clocks is the lowest I've gone. Along with 60% power & temp target. Also, I've successfully attached two PSUs, but I'm getting the same problem. I'm going to try the other 6+2 pin cable and some lower clocks. I'll report my results.

I finally got it working.

@anyone with a Y580 & trouble with eGPU, this might be useful
The trick was doing a -forcepstate 0,2. This bench was with identical settings as before when it was crashing, so I guess there is an issue in my BIOS which has trouble dealing with the dynamic boost clocks. My stock, default VBIOS for the 660M is integrated with my main BIOS, so I think this may be where the main issue lies. I've been using a bios I modded based on slv7's modded bios for higher 660m voltage, but changed it back to stock thinking it was the problem with my eGPU setup. The unlocked BIOS would be better to use since it allows the changing of link speeds for all the PCI ports && CPU tweaks for better performance that would not be available in stock BIOS. GLHF

Yes, use two PSUs. Use one via the floppy molex to provide the 75W slot power to the PE4L. Then plug your second one PSU with it's 6-pin pci-e power into the GTX660. I've often done this using two old 12V/16A PSUs to drive GTX770/HD7970/R9 280x all of which have the 75W slot, 75W 6-pin pcie and 150W 8-pin pcie power.
Which PSU should the SWEX be on? I'm assuming the one with the 6-pin?
Thanks for helping me out btw.
EDIT: Scratch that, I think I need two SWEX adapters to use two, otherwise one PSU would remain off.
Or would it be possible to:
--- Key ---
PSU1 = has 6-pin pcie power
PSU0 = does not
-----------
use the 20 pin power plug from PSU1 and the 4 pin from PSU2 on the SWEX switch?
-
At least then you can run the slot using one PSU and the 6pin pci-e power with your existing one.
Not sure if I understand you correctly. Do you mean use a PSU without a 6-pin pcie and one with the 6-pin together? If that's the case, I have another PSU (in fact, I have ~2-3) without 6-pin power. If that's what you meant, then how would I set it up?
-
Per advise of previous post, change your link speed from Gen2 to Gen1 and then load the system. Do you find it stable?
A GTX660 has only a 140W TDP max. I guess you might have an OC version which will be higher. I was not able to see any mention of the PSU you are using in any of your older posts. Keeping in mind that the PE4L-PM060A uses only a single rail of a PSU, hence why high watt single-RAIL PSUs like a Corsair CX430 are recommended for use with it. Pls check your PSU to ensure it has at least a 12V/16A (192W) rail to drive the GTX660. Better yet, test it with another PSU just in case your PSU is faulty. Yes, PSUs do deteriorate especially when overloaded and when they do you'll see unreliable power delivery.
I've been doing most of my troubleshooting on the gen1 x1 default 1,2 switch. I'm using an "eagle voltas" 600W PSU. Model: ET-PSVT600E.
Specs are:
DC output, max output
+3.3V, 28A
+5V, 34A
+12V1, 17A
+12V2, 19A
-12V, 1.5A
+5Vsb, 2.5A
This PSU has less than a year's worth of use, so I don't think deterioration is an issue. It's also the only PSU, with 6 pin PCI cables, I have; so I'd rather downclock/downvolt before getting another PSU. That is, if this PSU is incapable. There is also a 115V/230V red switch on the back of it, which is set to 115V (if relevant), but I'm in the US, so I think it's supposed
to be 115V.
There are also two empty ports on the PE4L adapter, one is a USB and the other is a standard circular DC port like the ones routers use. I'm assuming for my setup those two should remain empty?

Alright, so I'm stuck now. I have a PE4L-PM060A, Gigabyte GTX 660 and a Y580. I was able to successfully detect the gtx 660 using the slot where the wifi card is usually occupying.
My problem is that whenever I put it under medium - high load, it will (sometimes) hang/freeze/BSOD or (most of the time) auto-reboot. I know the GPU isn't borked because I tested it in my desktop. I know PSU isn't the issue because I used it when I was testing the GPU in my desktop. I THINK the PE4L is fine because I was able to successfuly use my old GT 220 in benchmarks and under heavy loads, using the same PSU. I used DDU to uninstall my previous 660m driver, then installed latest drivers for the gtx 660.
I've also tried the red and black jumper cables, and both pci 6 pin cables on my PSU (one of the 6 pin cables also has what looks like an optional, 2 pin, if that matters). I disabled discrete graphics in my BIOS. The integrated graphics, Intel HD 4000, must not be disabled from what I've gathered googling, so I didn't touch any other BIOS settings. I even tried a different mpcie slot on my laptop, which is for an optional modem card I think. I have also tried ALL combinations of the two switches (for 1,2 x1 lane / 2,3 x2/4/8/16 lanes && "dealy"/delay) on the actual PE4L adapter. One last thing I tried before giving up was switching from the 4 pin peripheral ---> (smaller) 4 pin cable adapter to the natural/regular small 4 pin cable.
I've read a couple posts where an eGPU setup on the y580 was 100% working. So, I know I something isn't right. Someone please tell me what I'm doing wrong & help me out! D:
EDIT: To clarify, what I mean by medium-heavy load is anything that is not the GPU-Z render test ^^

I probably am wrong, but I would speculate that either the cable of the PE4L is maybe faulty (I had the same problem with a defective cable from an EXP GDC) or maybe something else.
But if my understanding is correct, the internal screen doesn't work, whereas the external work but whenever you run an intense GPU program, it crashes?
Yeah, it crashes. And by crashes I mean it become unresponsive to the point where a hard reboot is required.

Hey, do you think you could help me with an issue I'm having? I just bought a GTX 660 & PE4L-PM60xxA. I disabled my 660m discrete gpu through bios, and was able to have the gtx 660 detected. My problem now is, every time I go to run any 3D application, I'll either get a BSOD, or it will reboot automatically.
Also, whether or not relevant, I should add that the LCD monitor on my laptop looks like it is on, but it's black. As in, only the screen's backlight is on, but no image is displayed. I'm currently using an external display via HDMI, which is working. I have all switches on 1_2. Another point which might be worth mentioning is: after trying to run 3dmark11, it returned an error stating out-of-memory exception has occurred. I have been unable to reproduce this error, since it just BSODs or auto reboots. I am running Windows 8.1.

Also, when I try and run a benchmark, sometimes it'll return an error: "out-of-memory"... I have 8 GB of regular ram, card has 2gb. So...? Any help is appreciated.

Do you think you could try and explain exactly what it is you're uploading one more time please? I would appreciate it, thank you.
