Latitude 7450 Owners' Thread

@gusf1 theres no pcie 2242 ssd on market, only sata

 

If the model you ordered only has 1 SODIMM slot, then that must be difference in the chassis that allows space for the 840m, since the i7 I ordered from Dell in the US has 2 SODIMM slots. There is only one i7 model available in the US, and it has 2 x 4GB DDR3L 1600MHz SODIMMs. I'm not sure if any of the i5 or i3 models have only one SODIMM slot or not, since there's not many configuration options available.

I tried a few other settings within the BIOS and it seems there's no way (at least, no easy way) to get the WWAN PCIe slot to recognize a 42mm M.2 SSD. I tried in legacy and UEFI modes, AHCI and RAID, and disabling/enabling the WWAN settings in BIOS. In Windows and Linux, the drive was not recognized.

There are a limited number of 42mm M.2 PCIe SSDs available (Transcend, MyDigitalSSD, and ZTC to name a few). Disregard as these are SATA, not PCIe.

 

M.2 slot can connect pci-e, sata or usb card http://en.m.wikipedia.org/wiki/M.2 unfortunately those ssds are sata only. There are some pci-e on market, but 80mm long (2280 m.2)

 

Now that you mention it I can't find any for sale, although @Svnyster reckons there are, and I found this: http://us.apacer.com/products/M.2-PT42-M/SSD/ so it may be possible to find one somewhere.

Having seen a bunch of other threads about the PCIe vs SATA M.2 cards not working in whichever devices I'm not surprised the SATA one doesn't work - if I find a PCIe one on the market I'll give it a try.

However I have a 1TB mSata on order so that will keep me going for a while (I only had 256 + 512 in my last portable device) - plus I have a cheap 128GB SD card (slow but ok for local backups)

 

You're both correct. I wasn't paying attention and I thought that the M.2 form factor was strictly PCIe, but I now see that the drives from Transcend, MyDigitalSSD, etc. are SATA. Like gusf1 said, Apacer does make a PCI3 M.2 SSD, but it's maximum capacity is currently 64GB and I don't think it has been released yet.

 

No. I didn't and I didn't get one either (so Dell aren't stupid eh ?)

For the non touch version, I ordered a Full HD and as the vendor confirmed by chat, it is a wide viewing angle. So I'm pretty happy with it.
As is been mentioned before, there is noticeable light leak (for me on the bottom), but only on a full black picture. It really doesn't bother on normal usage.

 

I'd also like to know that...

 

Thanks for the internal photo. Dell realised that an mSATA + interposer sitting in a 2.5" bay wasn't the best use of the space.

I presume the fan is a size bigger than on the non-dGPU version. Does this model run very quietly when the CPU is under sustained full load (eg wPrime 1024)? My E7440 gets a bit noisy under that situation.

The picture looks very similar to the E7250 manual.

I wonder if there are 2 versions of the 7450. One without the Nvidia 840m gpu but with a 2.5" sata slot, while another model has the 840m gpu but no 2.5" sata slot, instead having a msata slot for the storage system.

 

@thenew3 yes, there are 2 versions of 7450 - nvidia with msata and just intel gpu with 2.5 sata with msata imposter
