Dell Precision 7540 and 7740 Owner's Thread

Thank you so much for the excellent inputs.

Problem is that I do not have my 7540 yet to check the BIOS. The inputs I have given on top are from the downloaded manual.

Will request if some owner of 7540 can comment on at least what is visible in the BIOS...

 

Thanks @xklis I must have been mis-remembering two M.2 SATA drives vs. three. Anyway seems likely that the 7540 will work with at least two.

 

I don't think you'll have any problems using a sata drive. There's a ton of options in the bios. It's a bit of a pain to navigate though as it just displays everything on one long vertical list.

Mine arrived last week. I loved it. Apart from a little flex in the keyboard, it's a solid laptop and the addition of a number pad is nice.

Unfortunately, I had to send mine back as they had screwed the M2 screws on the keyboard so tight that I couldn't change the 8GB memory module underneath (it was an outlet model). I tried three or four different M2 screwdrivers that I have used with several other motherboards and laptops and they couldn't budge it. The thing is, most of the screws turned easily. It was just one in the keyboard that was tightened so hard I couldn't move it at all.

The hyper X CL15 2666 mhz memory I placed in the back wouldn't register as a result of that. Nor did the Samsung RAM I borrowed from my HP ZBook Studio G3 (as the single 8GB module couldn't be removed).

I did a video showing the laptop before I returned it that shows what the laptop looks like etc.



Despite my experience, I would buy from Dell again as they didn't give me any problems with the return. They did offer to take the laptop back for a week or so to replace the screws, but I was worried I'd run into the same problem again. I guess I could have just asked someone to install the memory for me at their centre so I'd never have to deal with that.

If definitely buy the 7540 again if a model that has 64GB+ memory installed already.

 

Decided to repaste and undervolt mine too since it reached 100C and got throttled even under single thread load. Quite shocked by all the scratches on the heatsink, is this normal nowadays?

That black one is deep, can't polish it away.

 

100 degrees seems excessive. I didn't get a chance to push mine to see what temperatures went to.

I'm not sure how the heatsink would have scratches like that unless it was scratched before it was connected to the motherboard.

thank you so much System0 for the inputs.

some quick questions. request urgent responses as I have one last chance to change my order in next few hours!!

1. is the FHD UltraSharp Touch display glossy? please note I am asking about the Touch variant...
2. is the FHD UltraSharp display bright enough as compared to QHD? read in manual that they are 300 NITS vs 400 NITS respectively...
3. what is the hit on battery life on upgrading from FHD to QHD? manual says that they are 6.5 W vs 10 W respectively...
4. how much is the hit in battery life if you run the QHD on FHD resolution? i mean if i configure to run QHD on FHD resolution and similar brightness say as the FHD...

hope someone renders timely response(s). thanks in advance...

 

The touch panel is glossy. All of the non-touch panels on offer are matte.

 

Awww.... Unfortunately, my order cannot be changed now.

However, on the positive side, I would certainly like to have additional battery life and touch. So no regrets.

I just hope that the glossy panel is not too glossy, is bright enough and can be used outdoors. Inputs from members owning 7540 with FHD touch screen are solicited please...

 

so I tried to polish it to the best of my abilities, did a repaste using Noctua NT-H1 (already had it lying around) and undervolted by 120mv, CPU and cache.
Temps are now better controlled, single core stays at 4850MHz under load, 83C. I don't understand why doesn't it go all the way to 5GHz.
All cores load can keep 4.2 for a while, then stabilize at 4GHz, not too bad.
@Hopper82 : where did you get the heatsink? I can't even find the part number.

 

Man, 83 degrees at 4.85 GHz—that is seriously good.

Sometimes this tropical weather does me no good.
