Ask vendor for the Support Tag.Performance upgrade: mSATA SSDYes, there is a mSATA slot in the E6440, though is not visible when taking the rear cover off. It needs the left bumper cap removed. It's situated above the WWAN marking as shown in the spoiler below. In fact, this slot is WLAN(PCIe1), mSATA (SATA3 port4) and WWAN (USB 2.0)!! Sharing the PCIe and SATA lines being a new Series-8 Flexible I/O chipset feature : http://forum.techinferno.com/diy-e-gpu-projects/6882-series-8-flexible-usb3-pcie-sata-pcie-i-o-some-more-x2-2-0-possibility.html#post94382 Performance upgrade: i7-quad CPUCan effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-4610M will not void warranty while a i7-quad will void the warranty if Dell know about it as it wasn't offered with one. I'd keep the original CPU back and swap it back in if necessary. Upgraded E6440 i7-quad system examples are shown in the table above.One important consideration is whether to get a 37W i7-4702MQ (4-core turbo=2.9Ghz)to keep within the factory-configured CPU's TDP or get a faster and hotter 47W i7-4800QM/i7-4700MQ (4-core turbo=3.5/3.2Ghz). I'm of the opinion that the 37W one should be avoided. That's because (1) the 47W CPUs can be software limited to 37W (2) XTU/Throttlestop allows a negative offset voltage offset to be applied bringing TDP down and allowing higher multipliers to work and (3) the beefier dGPU-model heatsink that can handle the higher TDP and can be retrofitted to the iGPU-only model.The E6440 BIOS locks the TDP but allows extra turbo bins are accessible using either Throttlestop or XTU. Eg: a i7-4700MQ has +200Mhz unlocked turbo bins (max=3.4Ghz 4-core). A i7-4800MQ has +400Mhz unlocked turbo bins (max=3.9Gbz 4-core). Problem with the 47W TDP limit is it limits performance to 3.5Ghz during a TS 32M/1024M 4-core load test. That result being *after* voltage optimization in XTU/Throttlestop. Meaning then that max performance lies between a turbo unlocked i7-4700MQ (3.4Ghz) and i7-4800MQ (3.9Ghz). Eg: a i7-4710MQ (3.5Ghz 4-core) would be at max TDP limits. Though those newer CPUs are rarer and often pricer than a faster i7-4800MQ. Means then that for the majority of users, a i7-4800MQ gives an easy plug'n'play installation from which highest performance, within TDP and thermal limits, can then be extracted easily using Throttlestop or XTU.RECOMMENDED reading: 1. http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post951812. INFO: dGPU_heatsink - improve iGPU model cooling by retrofitting dGPU model heatsink+fanPerformance upgrade: external graphics (eGPU)RECOMMENDED reading: INFO: EC_retrofit - retrofitting an expresscard slot to a E6440An eGPU has been implemented on a E6440 using a NVidia GTX770 (Tech Inferno Fan), AMD R9 280X (Tech Inferno Fan).DIY eGPU: attach a desktop videocard via the E6440's 5Gbps expresscard slot. Provides accelerated gaming graphics, CUDA/OpenCL processing and additional HDMI/DVI outputs to drive multiple monitors. A NVidia or AMD card is a straight plug-n-play implementation on a E6440. The system must boot least once with the eGPU attached and detected by the BIOS. This lowers TOLUD from 3.49GB to 3.24GB, storing it in NVRAM thereafter. Both my GTX770 and R9 280x can then be allocated without any error 12. In addition, no PCI Reset Delay mechanism is unnecessary and is best to be disabled. Then the system and eGPU can support a sleep-resume cycle with eGPU activate on resume. NOTE: The A.02 BIOS handles the eGPU beautifully, running a Gen2 expresscard link. Unfortunately bios A.05 or newer sets the EC port to Gen1 speed if you hotplug the eGPU after BIOS boot (see details). Flash back to A.02 to get the faster Gen2 link speed OR disable any PCI Reset Delay mechanisms on the eGPU adapter so the BIOS sees the eGPU on boot. Note: E6440 iGPU-model can boot with powered eGPU powered plugged into EC slot. dGPU-model E6440 will not boot with powered eGPU plugged into EC slot and so requires hotplugging after boot. In case anybody is wondering, a x2 2.0 eGPU link is not electrically possible unless there is a USB3 port 4 on a docking connector so can use the http://forum.techinferno.com/diy-e-gpu-projects/6882-series-8-flexible-usb3-pcie-sata-pcie-i-o-some-more-x2-2-0-possibility.html#post94382 feature. The USB 3 ports on the system are 1, 2, 3 and 6. The E6440 PCIe port layout is shown in the spoiler: If want to experiment with a x2 2.0 eGPU implementation then suggest look at a one-gen older Dell E6430. It's has two mPCIe ports (port 1 + 2) as per the E6430 schematic. System mod: LCD upgradeUpdate Feb-2015: newer E6440 has eDP rather than LVDS connected on the systemboard, with a 1920x1080 LCD option. See details. The FHD LCD retrofit parts required for the 1st E6440 series are in the spoiler: NOTE: The Intel iGPU Control panel mistakenly lists the LCD as being eDP as explained in the series-1 E6440.768P->900P is possible as a user upgrade. Required is swapping the HD 1ch LVDS cable for the 2ch LVDS HD+ and of course changing the 768P LCD for a 900P one. The two different LVDS cables available for a E6440 are: The two different LCDs being: My system came from the factory with a 900P AUO B140RTN02.2 panel with Dell p/n 0M4RTT. I find brightness and viewing angles quite satisfactory. A photo of my 900P LCD's model labelling is in the spoiler below. 1080P or higher resolution : not possible since the E6440 uses a LVDS rather than eDP internal LCD interface. The max resolution available in 14" LVDS is usually 1600x900, representing 37% more viewing area than 1366x768. Though ebay has 14" 1680x945 LVDS LCDs, giving an additional 10% more viewing area over 1600x900 or 51% over 1366x768. --> 1680x945 LCD does not fit correctly as attempted here.System mods: coolingINFO: dGPU_heatsink - improve iGPU model cooling by retrofitting dGPU model heatsink+fan.

Well guys...so now we know... What are your thoughts and first initial impressions? Do you foresee the new cooling design being able to cool the 1080 better than DTR's/Clevo's? Are you going to be ditching your current AW to get the new one? Will you be buying a different brand all together? Reason for the switch? Are you willing to pay DTR prices for the new AW if it turns out that way? (AW 1070 pricing is now available) Which screen option will you be opting for? FHD, QHD, or 4K? Do you care for Tobii? How long do you normally keep your laptop? -> Do you normally upgrade every year with the latest refresh? --> If so, is having LGA/MXM really practical for you? Things that I like: "...magnesium alloy for rigidity, copper for better performance and steel...." ".....overclockable DDR4 system memory capable of up to 2667 MHz overclockable DDR4 system memory capable of up to 2667 MHz....." ".... 17" QHD 120Hz display is designed to deliver the smoothest gaming experience with 4ms response time, wide viewing angles, 400 nits of brightness, and NVIDIA G-Sync technology...." "....a thinner design, better ventilation, higher quality sound and external ports organization...." ".... larger and more effective speaker box has been installed, improving audio output for a clearer and more dramatic gaming experience....." "....Avoid excess cables and embrace the “desktop mode” design, where most of your critical connections and ports are in the back and out of the way....." "....We offer the maximum amount of battery power legally allowed with the 99 Whr battery– storing and delivering the most amount of power found in any notebook battery for longer uninterrupted game play....." Don't forget the LED lighting that unlocks the BIOS and makes the AW hover for better ventilation. On another note, this is one step in the right direction...it can breathe I take it... What we know so far (stuff that we actually care about): * New AW17 1080 will be 180W and GDDR5X https://www.twitch.tv/alienware/v/87746534 (Thanks @DeeX for the heads up. Also confirmed from the horses mouth himself, Azor.) @ 4:46:26 …mentions 180W @ 4:49:33 ...worth watching it from here, lol... @ 4:50:10 ...takes a crack at Clevo...I love DTR's, but what he says is true. No heart behind Clevo's design, just a bunch of rebranded, rebrands. * Full on Copper heat sinks and heat pipes. * Back of display is metal. * Bottom of laptop is metal, anodized aluminum. * Laptop is very rigid. Watch them try bending it...it's solid as a rock. Lots of metal. * Keys on the keyboard are guaranteed and rated at 10 Million strokes. * Keys have a longer 2.2mm travel length. * N Key roll over technology. Able to register multiple keystrokes. * 19 Total Macro Keys. More added near the Num pad side on the 17". * The back plate of keyboard is steel enforced, all metal. * Bottom and Side air intakes. * Designed to keep the heat toward the rear and away from the front areas, keyboard / palm rest. ____________________________UPDATE (9/14/16)____________________________ Well guys: Click here Here are some early pricing (out) comparisons. I've been playing around with different configurations to get an idea of what we can expect for the overall pricing. I've noticed that it is a bit more ala carte in a way...well kinda... Note: It's possible that my numbers are off and if it is then I'll update it, but please do go price it yourself if you have a moment... Couple things I've noticed: * There is an option to get a display unit without Tobii. Thank goodness. I wonder if this is true for the up coming QHD panel? * The price for the 4K UHD w/ Frobii is outrageous. +$400?! Sheesh... Hope they offer 4K without Frobii. ____________________________UPDATE (9/23/16)____________________________ www.Alienware.com is now LIVE with pricing of the new machines, but only up to GTX 1070 configurations. --- Early Comparisons of an Alienware 17R4 (GTX 1070) vs Clevo P775DM3 (GTX1070): (Blue = Better / Red = Falls Short / Grey = Equal) ------------------------------------------- Clevo P775DM3 / Fager NP9172-S * i7-6700K * 1080 FHD w/ GSYNC * GTX 1070 * 16GB RAM DDR4 2400MHz * 256GB M.2 SSD * Killer 1535 * 2 Year Warranty …$2,114…NO TAX w/ GTX 1080: $2,502 Options: * 4K UHD w/ GSYNC is +$275 ________________________________ Alienware 17R4: * i7-6820HK * 1080 FHD w/o GSYNC * GTX 1070 * 16GB DDR4 2400MHz * 256GB M.2 SSD + 1TB Paper Weight * Killer 1525 * 2 Year Warranty $2,474 + PLUS TAX $198 (Avg. 8%) = ...$2,672... Options: * 4K UHD w/ Fobii Eye Tracking is +$400 ________________________________ Reality in terms of value to cost ratio: * 6700K (socketed lga) > 6820HK (mobile bga) * GTX 1080 for only $275 more on the DTR. How much more will GTX1080 be on the AW? * 1080FHD has GSYNC on DTR * Can paying $558 More for AW17R4 be justified? ________________________________ Current thoughts at this time and moment: Well to be honest, as for the pricing it doesn't look good if the numbers on the pricing page is anywhere near accurate. There's no way that I can justify paying ~$558 more at this point, however, that can change depending on the GTX 1080 and QHD variant. It's too early to tell. I'd like to also add that the 2 Year Warranty for Dell is "Blue," because it is far superior than Clevo's 2 Year Warranty. This is a fact (at least if you're in the US), so please let's not argue about this. As I've said before, "Do not pay DTR prices for a bga machine." This is just my opinion and everyone is entitled to their own, but please do the math and make a wise decision that best fits you and your needs. Notice that the comparison is between the AW17R4 vs the Clevo P775DM3, which is not the bulky DTR, but the more slimmer and (IMO) cleaner looking one. What are your thoughts?
