Much thanks @Chamelleon - yeah the i7-4702 would def be a safe choice as it has the same TDP as the i5 I currently have. It would be my next choice. 

 

But i7-4800 is the same exact price as the 4702 and is about 15-17% faster,

 

If someone can confirm if there's no throttling with i7-4700/4800 or any other 47W TDP CPU while dGPU is in use, I would totally go for it..

Don't know why it disappeared off here. Found an archive at http://web.archive.org/web/20150829044909/http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html

 

I'd say stick with the i7-4702MQ. Dell E6440's cooling system isn't up to dissipating the heat if try to increase UEFI TDP values of the i7-4800MQ processors to allow function in their upper multipliers.

Hey!

 

I am about to buy a 2nd revision FHD IPS version of E6440 and of course I would exchange the i5 CPU to a quad-core i7, my only problem is that I cannot find suitable 4702MQ CPUs on the market, while there are plenty of 4700-800MQs around. I wanted to read about undervolting these CPUs, but the link is somehow dead, as it was mentioned before, but I cannot find anything even with Wayback Machine. Could you provide/re-open the topic to see your results?

 

Cheers,

Marton

Great topic that's as I'm finding the 4810MQ hits "Current Limit Throttling" very quickly (even when idling) and as a result the Package TDP never goes up above 23W with a max core frequency of 2.4Ghz and a package temperature of 70°C, which is very odd. Does anyone know of a way to remove that limitation ? Thanks !

Does any one have a problem with iGPU Boost speed? Mine never goes to 1200 under load. Only bounces between 650 and 850.

Also has any one managed to overclock the iGPU succesfully? Uefi values or Intel XTU dont seem to work.

Config is i5 4300m with iGPU only. 2 x 4GB at 1600mhz, Windows 10.

you should go to intel HD Graphics Panel and set it to Max Performance, after doing so, mine became full speed (1299 Mhz I think)

Good afternoon I'm new to the forum and also new as owner of a Dell E6440 without dgpu. I would like to put an egpu. I have some doubts More the main doubt and that my notebook has the card exprecard and the bios is updated to version A23. I would have problem with gen2  PCIe speed?

Many thanks for the reply. I'll look for a good vga for this dell e6440. I'm thinking of a RX 560. And in the eCPPU EXP GDC adapter. Any suggestions for this newbie? Thanks again for the quick reply.

Parece estar trabalhando @ v21, então, suponha que esteja funcionando também com @ v23.

 

I was happy when I saw the gpu-z PCIe x16 image. More I remembered that only the information from the left side to the current band used by the pcie. :)

Hey all! I recently got a second hand dGPU E6440 (i7 4600M) from a guy on FB marketplace, the machine looks and works all ok (after some troubleshooting), however it suffered from extreme throttling (as low as 0.4MHz)

 

After long troubleshooting I've managed to solve the issue with ThrottleStop, I think this happens as the charger he gave me is a generic one.

 

However, the machine was suffering from Thermal, Current Limit and Power Limit Throttling as reported on XTU

 

To solve Thermal I bought some Noctua NT-H1, which works for shaming periods of time, I've changed Paste easily 4 times on a month:

First time I opened it the Paste it had was horrible at the least, I cleaned it all and applied a small blob to both chips,  got temps down from 80C on Idle to high 40s, low 50s, while gaming it held a solid 97C (with its sweet dose of 97C PROCHOT), which ultimately always caused my CPU to go 0.4MHz if I gave it the time to do so, after new paste it reached 85-87C at full 3.5GHz TB)

 

Couple weeks after, I opened it up as 97C and Thermal Throttling came back, but before that I noticed CPU wasn't working on Turbo anymore while gaming, however when opened it up I noticed that the paste slid al out of the Dies, so I thought I used too little and re-cleaned and re-applied, a slight higher amount on both chips, and monitored temperature more closely.

 

Turned out the same, four days later I was pretty sure the same as before happened again, I opened it and all the paste had slid out of both chips and temperatures were going high again.

This time I applied a good bunch of paste (that's a no-no for me, always, but what else could I've tried? I'm pretty sure there's enough pressure on all screws [EXCEPT for screws 5 & 6 on the GPU part of the Heatsink, they seem to stand out while all others seem to go deeper, however, they will not go deeper despite how much force I put into, it feels like they're seated])

 

This time It lasted a couple weeks again, doing some VRAM underclocking kept *96C* everything from Thermal Throttling, however when I opened the computer to check, the paste did slid out of the Dies already, this time I only applied a regular amount into it and haven't done anything else since, but  I'm pretty sure this persists.

 

Pictures of what it looked like when I opened it the fourth time and screws that I feel like not reaching bottom:

Pictures

 

Room temperature has been around 25C max and mins of around 5C

Could this be the Noctua's paste consistency?

Might be the screw I'm mentioning?

 

Can someone provide me with a Screenshot of "Primary Plane Power Limits on TPL section on Throttlestop? As far as the program creator told me, there's one point while gaming that my Turbo needs to be shut down as my GPU isn't getting enough CURRENT, he said that the locked value (55 on mine) was what it was causing it, and if it wasn't editable I was pretty much stuck with that, in that regard I'm planning on upgrade to a 4800MQ, but I'm concerned that I will not get it's maximum E6440 potential as I'm stuck on PPL CL 55, Throttlestop author told me the ideal value should be 100. I've tried to extract my BIOS and modify Power Limits as described posts up, however I get "Error 201: [FPTw.exe] cannot be run on the current platform. Please contact your vendor." with no solution yet, I wonder if the FPTW OP uploaded was different than the one I found on the web, I looked for the same version tho)

Also, could anyone provide Gaming benchmarks using a Dual and Quad? Will it benefit framerates to get a Quad? I know on instances where CPU is at 100 and GPU lower than that it will certainly help, but how about non-bottlenecking games?  I use this machine for content creation too, so I'd get benefits from a Quad anyhow.

 

Thanks fellas!

I'm gonna answer to my previous questions and post some information for -hopefully- posterity, as there are some older posts quoting some dead links, I've digged on these subjects and found the most reliable and easy methods to do so, this is a great machine, it can stand for non-gaming battle all through 2019, I'll be updating this post over time.

 

As a note, right now the i7 4930MX is sitting at 183 Euros on Aliexpress (they price it on EUR), the 4940MX is around 300, and it's only 100MHz faster, so best price-performance relationship as of early Jan 2019 is 4930MX

 

Edit 1: First batch of info:

 

Thermal issues

 

I've managed to extend NTH1 cooling activity by leaving the paste curate (repaste, boot up, TSBench 1024 4 Threads Twice [takes about 6 mins each pass on 4600M Stock], Shut down for 1 hour, then normal use.

I'm using a cheap fan under the laptop as well, temperaures have been sitting around 48-52 idle with Clock modulation on, on Power Saving goes almost 45C, during load has peaks of 90-94 AT MOST, before used to be 97C PROCHOT (slight throttle to avoid TJuction) and around 105 on the GPU (CRITICAL TEMP)

I'm waiting for this Kootek Chill Mat 5 I ordered, it stands as the best cooler out there on several tests, reducing up to 30C internal temps, yes you read right 30C.

 

HOWEVER I DO NOT RECOMMEND NOCTUA NT-H1 for this laptop, to me it seems that there's a gap between heatsink and CPU/GPU Die

Planning on buying either liquid metal or Kryonaut, following the pasting guide by verei at NotebookReview: ThrottleStop - Overclocking Dell Precision M6800, I will update on this later on

 

Turbo Power Limits (TPL) - Removing CPU TDP Limits

 

In order to modify CPU TDP and Current constraints we need to modify the BIOS, the most reliable, fast and easy method is to use a NVRAM editor (Notice that if you want to reset these values to default you should either re-do the process entering the default values or remove your CMOS battery)

 

As of 2019 FTK8 gave me Error 201 with BIOS from A02 to A23 and wouldn't dump the bios, as the variables are already known, we're gonna skip this part of the process used by Atonus (WORKAROUND AVAILABLE)

Spoiler

It turns out that Dell did indeed turn of any RAID settings and hid it from the common user. Or rather didn't make it visible. What you have to do to enable RAID on the Dell Latitude E6440 is:

- Download https://www.sendspace.com/<wbr>file/bouk3i


It's a flash toolkit by Intel with additional batch scripts mostly for Asus boards. You can use fptw to dump your current or flash a new BIOS.
- Extract it to C:\. The new path should be "C:\FTK8_0.11\Windows"


You can extract it, where you want. However, it will be easier to handle the next steps, if it is C:\.
- Start > type "cmd" > right click > Open as Administrator.


You need full rights to run fptw.exe
- Type "cd C:\FTK8_0.11\Windows" to change your current directory to the toolkit folder

- Type "fptw.exe -D backup.rom -BIOS"


This command will create a dump (-D) of the BIOS section (-BIOS) to the file backup.rom. The Management Engine section for example is read/write protected, so it won't be possible to do a full dump.
Then you can open the dump with "UEFITool" (just search for it on Google), then search for and extract the module SetupPrep, when you find it, run it trough the "Universal IFR extractor" which will generate a text document of the input. I attached my text document down below so that you can compare. SetupPrep IFR.txt

The interesting part is in my case in line 2030. It tells us the name of the setting ("RAID0"), the hexadecimal address in the NVRAM (0x19D) and its possible values (0 - Disabled/ 1 - Enabled).

 

Spoiler

WORKAROUND

Head to verei's variables after Atonus's

 

 

In order to do so you need to download This NVRAM Editor, paste the EFI folder on the root of a FAT32 USB Stick, reboot, F12, boot from usb stick, once in there we're going to use Atonus's BIOS variables, As well I used those in the post that verei quotes on his guide.

 

Once in GRUB in the NVRAM Editor type:
setup_var VAR DV

 

Where:

VAR is the Variable I.E. 0xC9A or 0x54

DV is Desired Value I.E. 0x0 or 0x1

 

Examples:

setup_var 0xC9A 0x0 to Disable Package Power Limit

setup_var 0xC9A 0x1 to Enable Package Power Limit

 

Atonus's Variables - RED Means TARGET, BLACK Means Default Value

Spoiler

CPU TDP Variables

Package Power Limit Lock - Variable: 0xC9A
Disabled, Value: 0x0
Enabled, Value: 0x1

 

Platform Power Limit Lock - Variable: 0x54

I know this topic is years old, but the E6440 is my current laptop and I've run into a problem with an eGpu  if anybody is around to give assistance.

Basically, I have dedicated graphics of 4600 and I bought a gtx960 to get a bit more gaming juice, ive plugged it into the port closest to the Right speaker (I believe it may be 7, the express card slot in a previous picture I'd seen) Basically, the GPU is detected but has error 43. I've followed steps and downgraded to 368.81, reset and it seems to say its working correctly in the device manager, I can also use GPU-Z to get it to spin up, however it doesn't seem to appear any graphics memory is being used.

(I have disabled the dGPU)

If I try and load up any game, I think it must be running on CPU only, because I get no more than 1fps

I think you haven't lowered TOLUD, how did you disable the dGPU? error 43 (as reported on EGPU IO) doesn't affect 9xx or older GPUs, therefore you can update to the latest (or your favorite) version drivers, basically you need to do the NVRAM work to enable hotplugging, lower the TOLUD and Disable dGPU (Not recommended), however if you're using setup 1.3, I think it can be all done from there, when had my eGPU I did the old fashion, DSDT Override and NVRAM values, it was another model tho, you can head to my post (Or search for Atonus's and ****** NVRAM values at page 2, theyre linked at the first post "Enable RAID", there are the eGPU NVRAM values at the end)

Sorry, can't help You in this case. I have iGPU only version and never had dGPU in any laptop for eGPU. I can also tell You that GTX960 is very picky in case of eGPU (I heared) and it won't be working on every setup.

CrzyGK has or had seme setup as You. I have iGPU + GTX780 and it's working on every BIOS and Driver version. I can boot with eGPU attached or hot plug it. But as I said it's completely different setup than Yours so can't help this time.

Does anybody know anything about getting a gtx960 working with an e6440? If I roll back the drivers it seems to detect it and accept it, I can also put stress on the gpu to test it, however I have no idea how to make it my computers gpu as NVidia control panel doesn’t load

Well damn I'd suggest going directly to ***********, maybe ********* could bring you some advice, also if the card is reported to be eGPU unstable look and try other setup's workarounds, they might work, good luck!

      Has any company out there launched a laptop with an external MXM port? 
       
      Just curious since with the boom in the gaming laptop market and some companies launching eGPU thunderbolt enclosures, isnt the MXM faster?
       
      Is it because of licensing issues? or hardware problems?

      Hello guys ...

      i wanna make sure that everything is going to work fine with my laptop so i got some questions

      First of all my laptop is Lenovo Z51-70
      CPU: I5-5200U 2.2ghz
      iGPU Intel HD 5500
      dGPU:AMD R9 M375
      Ram: 8GB (will raise it to 16GB)
      HDD: 1TB stock one
      SSD: 120GB (for my games and windows only)

      now i investigated  a little about eGPUs and found that i need a M.2 or thunderbolt, i've found that my wifi card use a M.2 a/e key aka ngff, so i will be using the GDC Beast NGFF version

      to the bad part / question part

      What do i need to know other than the stuff above?
      what is the white-listing thing? i found on support forums that my laptop support some wifi cards only and it's bios cann't be modified according to bios modifying forums (not here)
      in same time saw some posts on reddit that says if ur bios have UMA graphic option then you will need to disable PAX / WIRELESS and enable UMA and it will work fine, the question is that true?

      i wasn't able to find anyone who did it on Z51-70 i found only 1 post on reddit for Z41-70 (which after research found that both are using same M.2 a/e key slot and also same bios... but the one who posted only replied that it's recognized with some errors and never replied back with any updates so still not sure about it.....

      Hello everyone.
       
      I put on a eGpu setup after quite a bit struggle 2 years ago and I used play games just fine. After a while I sold my graphics card gtx 970.
      Now since 2 days I am trying to put the eGpu setup back again this time with a Gtx 770.
      I couldn't understand the problem. I can shut my dGpu off with diy 1.30 setup. ( usb booted)
      And my laptop sees  gtx 770 along with my igpu Intel HD graphics 4000.
      After driver installation when I try to play a game laptop is tring to use iGpu instead of Egpu. (tried to delete and install driver few times)
      With MSI afterburner I can see  eGpu is  %0 all the time.
      Can it be power problem cause graphic cards fans ( Msi gtx 770 twinfrost ) are working all the time they dont stop.
      Or what else can it be. 
      Thx.
