try to enable Intel Power Balance set CPU 31 and GPU 0. It won't go over 45W no matter what? Not even for a short time?

Could you upload a screenshot of your TPL in ThrottleStop?

Long Duration Power Limit 0xB40 [Power] To get the Optimal setting (no TDP Throttling), check with Throttlestop, (Example: 0x50 = 80W) Short Duration Power Limit 0xB41 [Power] Sets short duration TDP limit of CPU. Default value is +12,5% of the original (x64=100W) What do you mean safe? I have it like this for more than 3 months and it works great. I use mainly my 90W PSU and used my 130W for my Dock at work and when I OC my NVS5200M.

You are probably TDP throttled... Set your Long and Short Duration Limit @ 80W and 100W respectively (List of UEFI vars)

Nice!!! Follow the NEWBIE GUIDE TO TWEAKING THE DELL E6430 by badbadbad. If you have problems ask here. Would be helpful for your OCed temps to operate with bottom lid open and use laptop cooling pad (or a fan pointing on the heatsink). enjoy the power... if possible supply prime95 temps and add the 4C @ 3.8GHz temperature results... It would be helpful to evaluate how efficient your CPU is as done here as described http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 it would be interesting to see where your 3740QM ranks.

I don't think it would have any problem working if your screen is already 900p. The proble is as you can see above quoted from http://forum.techinferno.com/dell-latitude-vostro-precision/6980-14-dell-latitude-e6440-owners-lounge.html, it seems like the screen may not physically fit. Contact the seller for more info on the E6430. I have never tried it. If he accepts returns you can try it and if it doesn't fit send it back. Since my E6430 came originally with 900p I would be more interested on a real upgrade such as a 14" LVDS 1080p screen or an 14" IPS LVDS screen. If you find out that it fits but yours came originally with a 768p screen you will also have to buy the 2ch LVDs cable in order for the new screen to work correctly (same applies for an 768p-->900p upgrade). Part no for HD+ cable is JTC08 or CYM5C JTC08 is stated as HD+ cable CYM5C is stated as FHD/HD+ cable although there is no version of E6430 that would come with FHD screen. You can find one of these as low as 15$ but I can't find any info on what is the difference btw the two. If you are interested I could try to find what is my part number (my laptop came with an 900p screen and it is most probably going to be a JTC08).. Seems to me that the CYM5C is the cable for the E6530 version of the cable but it will work for the E6430 too. also it is the same cable for both iGPU and dGPU models. Successful upgrade from 768p -- > 1080p on a similar hardware E6530 laptop using CYM5C cable

Interesting! Do you have any proof that disabling the NVS5200M helps with your temperatures? I remember when I applied the battery tweaks that when I disabled the dGPU completely I had bigger idle consumption than when enabled but not using it.... I thought that the same goes for heat emissions and that's why I have it enabled...

Thanks, that was my first thought but I realised that the EC on the E6430 is on the motherboard... Top left And my e6430, your e6230 and khenglish's e6530( motherboard), worked flawlessly... I am thinking to grub some gear just for testing... Although I may have to say goodbye to this beauty since they got me a new computer at work...

I really can't find any reason why this is happening other than a hardware defect either from the laptop or the eGPU hardware. And since the whole setup works great on your 2570p I can only assume it is your laptop. Is there any other GPU you could borrow and try (even older)? I use to do my first test with an old 8400 with a faulty DVI I salvaged from work. Also use your Service Tag to check on your warranty. These machines came with a Pro 3 year warranty and it is very possible that it is still under it... If you are quite sure it is a mb defect you should contact them in order to replace it. Offcourse you should find another way to prove that the EC slot is faulty (maybe test with a cheap EC-USB 3.0 chip) cause I don't think they will fall for "Hey, my eGPU is not working @ Gen2 speeds..."

I am sure that my r9-280x hold a stable x1.2 link with my EC homemade adapter, even when running a couple of benchmarks. No Nvidia card was tested though. Also other laptops from the same generation (E6230, E6530) have managed successfully to establish a Gen 2 speed link. And the same problem shows on both you dGPU model and the iGPU model... I don't think that there is a manufacturer fault on your mb and the EC can not hold Gen2 speeds... Are you running the latest Intel driver? The problem is still in W10 or W8.1?

Follow this post to keep your iGPU enabled to avoid blackscreen. Check the next post for the variables

its ok I connected my screen on the R9-280x with DVI but I can't see how this is any different than your HDMI signal. You said that the same setup (adapter+card+screen) works flawlessly @ x 1.2 with your 2570p... That's weird cause it really seems like an adapter fault... Could you pls try to set your EC port @ Gen1 speed using UEFI vars? If your gear works fine with your 2570p it could mean that the EC port is faulty and it won't hold gen 2 signal... http://forum.techinferno.com/dell-latitude-vostro-precision/9690-14-dell-latitude-e6430-performance-upgrades-system-mods-19.html#post144322 you can find instructions here @sangemaru Is there any possibility to test your adapter with an other system to check if it can hold Gen 2 signals... Mine was working but AMD drivers was proved to be more versatile than NVidia in such cases

May I give an advise? Try uninstalling nvidia drivers and plug before post. Start up your computer (it may have a blank screen it is normal but it should start up after a while. If you don't see an image on your external screen after a while (it will take a little longer than normal) try connecting a screen on the HDMI port on your laptop (it is wired directly to your NVS5200M)... I didn't have any problem my EC with my R9-280x @ x1.2 running W 8.1 so I kind of doubt there is a hardware issue (I am not sure though cause haven't tested with an Nvidia card). Code 23 seems like an unusual error... maybe something going on between the mobile and the desktop nvidia driver? Try the above and get back

That's very interesting news... Keep us posted pls

Regarding mods it's probably going to be exactly the same... but IMO the 15,6 1080p is the only gain... On the other hand, It is going to be 20% heavier starting @ 2,449kg vs 2.014kg and bulkier... Regarding the CPU cooler, I think that although on overall usage it is going to be better, the dGPU model cooler is worse when you use an eGPU, cause the two pipes are dedicated one to the CPU one to the dGPU... So you are basically using a single pipe to cool the CPU while on the E6430 you take advantage of both pipes... On specs though E6530 was designed originally for up to i7-37xxQM processors while the E6430 is designed only for up to i7-35xxM processors. My QM though works fine

Happy it worked... Seems like we have to edit every MEFW... I am maybe going to try to flash the one I edited for you on my machine to see how it goes... Glad you made it... Specs? dGPU/iGPU mem CPU

That's the same behavior in my E6430 too. At least in the changes I have made so far... I feel like every time I powerdrain my machine (remove power bla-bla-bla) everything is back to stock settings, even BIOS settings such as boot from UEFI or legacy and I have to set again multis etc... I wouldn't recommend to play with these voltage steppings though. As far as we know it has nothing to do with CPU voltage. Although powerdraining may reset settings that doesn't guarrantee that you won't brick your machine... We better play with what we know... @Khenglish Found any EFI vars? Thanks

I assume you did change the clock range in ME FW in the DIV3 settings. Where can I set the BCLK OC in NVRAM? Text: ICC Overclocking Lib Suppress If: Variable 0x3DE equals 0x0 Ref: DIV-1S, Variable: 0xFFFF Ref: DIV-2S, Variable: 0xFFFF Ref: DIV3, Variable: 0xFFFF Ref: DIV4, Variable: 0xFFFF Ref: DIV-1NS, Variable: 0xFFFF Ref: DIV-2NS, Variable: 0xFFFF That's the closest I could find but this is also Text for BIOS readings , not Setting.. What am I doing wrong?

@Khenglish Would it be possible to connect the DIV3 clock with the DIV2 clock to OC the PCIe 2.0 ports (EC, mpcie) too? Or any other way to set the DIV3 clock to a specified value (e.g.105MHz)? It would be fun to see what performance impact such an increase would have. I think you had implied that something like this is possible with NVRAM settings? Couldn't find any clues though. Could we change it inside the ME firmware setting a different clock range definition? Will this make the laptop unbootable if wrong value set?

I don't really know.. I have to check this out... Thanks on your findings though

That's fair enough. Are you sure that the top bin values are valid? It seems like till x35 is has lower TDP than mine and then after x36 it takes bigger steps than mine ending at higher TDP... If this is true that possibly means that for some reason the newer chips (3740QM/3840QM) may have higher TDP on top 4 unlocked bins than the older 3720QM/3820QM series...will rerun my TDP data to confirm but we need more data for this one. Most probably with PEG...

If your original BIOS has 00 00 FF FF 00 00 FF FF 18 01 FF this means that someone before you unlocked it... Original BIOS from Dell would have locked every region of the BIOS (and make it unlockable through BIOS options for their update process). The last value FF means that the guy who unlocked it also unlocked the GbE region. We find no use and that's why we left it with the original value... There will be no issues with this region write-enabled unless you flash it with different values. If you have flashed the 6430oc.bin your ME FW should be unlocked.... Try reinstalling different/older versions of XTU... When it prompts for restart, shutdown and then start again... Just want to know to compare with mine what's your highest Voltage @ highest multipliers? If you have time test with Throttlestop as shown here link at the end of the post, to check how efficient your chip is.Thanks. You can see here that my 3720QM goes up to 1.2109V and it is much more efficient than my 3630QM. This will be a very interesting endeavour... I was about to try that myself but I didn't have an empty spare drive and enough time.. Will be happy to assist.

That's pretty nice... Maybe you should consider some of the cooling mods done on the HP 2570p... All of them showed quite an improvement in CPU Temperatures without spending too much (especially the "Anarchist" mod ) If you get your refund you will have Gen2 link and you will have much better results... That's true... I am not expecting a total cost of a 4C TB machine + Akitio + card +PSU to be under 1000$ even used... E6430 being x2.2 capable is maybe the only cheap 8GT/s solution so far with 4GHz+ 4C options!

How to keep iGPU enabled after booting with eGPU connected (Optimus Compression) UPDATE: Check next post for variables. That's great news for the E6430 community!!! This means that with the correct settings we can have both enabled iGPU and eGPU after a cold boot, no need for hot plug. This is also good news for Nvidia users since they will be able to have their card connected before boot and still enjoy Optimus compression (since iGPU is still enabled)... Also no need for manual setting of the TOLUD! Auto will work just fine. Could you pls elaborate exactly which vars you used to make this happen for other user reference? Are those from this post? What do you mean Firefox doesn't like being moved to internal screen. What is the issue? What if you set the internal screen as the main display? Still having problem? Thanks for your efforts... BTW 24" 1920x1200 16:10 rocks!!! No further change is necessary. It will automatically ramp up to the highest multi... Keep the bottom lid off, it will help a lot with the cooling. You will find out that you don't need to have the bottom screws in. The bottom lid stands there by itself... That's how I move it back and forth to my work every day for almost a year now...

I got mine from an auction @ 200$ + s/h with i3 4GB NVS 5200M 900p 320GB hdd backlit kb without a charger and in minor condition after a two-month search last year... So I think you may find if you can wait a little bit... My dGPU cooler handles an i7-3720QM 4-core @ 3.98GHz with maximum temps @ 95C with open bottom lid (running Prime95). Using something better than MX-2 may give better results... Consider also that: An OCed NVS5200M is up to 25% faster than an OCed HD4000 as discussed here http://forum.techinferno.com/dell-latitude-vostro-precision/9690-14-dell-latitude-e6430-performance-upgrades-system-mods-21.html#post144831, and (in case you are interested) a dGPU E6430 along with a docking station is capable to drive up to 3 External screens as shown here. If you decide to buy a dGPU model and you buy the charger seperately I recommend you grab the 130W adapter, since it will give you more headroom for the NVS5200M OC. You can find great deals on PR02X or PR03X docking station + 130W adapter for less than 40$ (including s/h). If going iGPU and you are planning to upgrade your RAM, seriously consider some fast 2133MHz CL12 memory to boost your iGPU graphics and general performance more, as shown here . (suggesting CL12 cause both sangemaru (3740QM) and myself (3720QM) had problems running 2133MHz @ CL11. An extreme CPU (3920XM, 3940XM) may not face such problems) IMO don't spend too much on an E6430. Consider saving money to grab a skylake TB3 equiped machine...
